Why org.hyperledger.fabric.sdk.Peer can have only one channel? We can join peer to multiple channels in Fabric.
```
/**
* The Peer class represents a peer to which SDK sends deploy, or query proposals requests.
*/
public class Peer implements Serializable {
private Channel channel;

hi all, i am a hyperledger fresher, and I was wondering, how to invoke hyperledger-fabric blockchain from my mobile (the front-end in the normal sense? ) We have node/java/python/go client for HF i know but that means they are actually backends, besides the codechain server itself. So does it mean we have 2 backends? The way it works is actually 3 tier Mobile -> A machines node code -> The machine's codechain code?

I'm not sure what your exact question is.
rickr (Wed, 13 Dec 2017 13:21:31 GMT):
If an application defines more than one orderer for the channel and you send a transaction without specifying which one explicitly we randomly pick one.
Ashish (Wed, 13 Dec 2017 13:23:15 GMT):
Hi Rick pls help, We are getting an issue while endorsing.. with 2 Orgs with AdminRole ( affiliation ) and AND condition..
We have setup a network with four Orgs, OrgA, OrgB, OrgC & OrgD.
Each organization with 1 Anchor Peer and one supporting peer.
Fabric version v1.0.3 [ docker images and binaries ]
Fabric Java SDK jar version v1.0.1 as 1.0.3 was not available. :(
Used the Cryptogen for creating the artifacts.
While defining the channel, we have specified configtx.yaml as below
OrgA - Role.Admin
OrgB - Role.Admin
OrgC - Role.Member
OrgD - Role.Member
&
Orderer : Solo.
With this setup, we started testing the endorsement policy with the help
of JavaSDK.
We have a simple chaincode, and the endorsement policy is as below.
identities: # list roles to be used in the policy
admin1: {"role": {"name": "admin", "mspId": "OrgAMSP"}} # admin role.
admin2: {"role": {"name": "admin", "mspId": "OrgBMSP"}}
user3: {"role": {"name": "member", "mspId": "OrgCMSP"}}
user4: {"role": {"name": "member", "mspId": "OrgDMSP"}}
policy: # the policy .. could have been flat but show grouping.
4-of: # signed by one of these groups can be -of where is any
digit 2-of, 3-of etc..
- signed-by: "user3"
- signed-by: "user4"
- signed-by: "admin1"
- signed-by: "admin2"
[ Note: Some portion in the read the docs mentioned to specify identities
in the reverse order of privilege and signature set in the increasing
order of privilege. But we have tried otherwise as well. ]
During the invoke from our java client, we are sending the transaction to
all the peers in the network.
We are collecting the proposal from all the nodes and the accumulated set
is being sent to the orderer.
But the transaction fails with status 10. [ TransactionEventException:
Received invalid transaction event. Transaction ID

rickr (Wed, 13 Dec 2017 13:33:42 GMT):
what is admin user ? This can not be the CA admin. That is just a ROLE memeber. If you look at the integration testcases there is a `peer admin` that user has ROLE admin

BTW if you want latest we routinely publish SNAPSHOTs see the README.md
Ashish (Wed, 13 Dec 2017 13:45:04 GMT):
Thanks Rick, will go through the README.md again.. and will dig it up.
While creating the channel, we had specified the Role.Admin and Role.Member in the *configtx.yaml as AdminPrincipal: Role.ADMIN & AdminPrincipal: Role.MEMBER*
Btw, if you mentioned the usercontext was set using the users generated as a part of the the generated crypto material.
he is similar to the guy who was setup as peerAdmin in End2End IT
the user who gets created in the /<>/crypto-config/peerOrganizations/OrgA/users when we create crypto material using the cryptogen.

Hi everyone, I've been seeing a weird issue lately. I have 2 orgs in the network, and the Java SDK is bound to org1. I also have a block listener in SDK application. In a lot of the blocks, I'm seeing data signed by both Org1MSP and Org2MSP, while I expect it to only have data from Org1MSP. Does anyone have any idea whats missing here?

If you are just starting out and learning Fabric BC I would recommend just getting the latest or use the v1.1 SNAPSHOT

I just tested locally JSDK v1.0.1 against Fabric v1.0.5 and it passed.
To get Fabric v1.0.5 before you start docker :
```
export IMAGE_TAG_FABRIC=:x86_64-1.0.5
export IMAGE_TAG_FABRIC_CA=:x86_64-1.0.5
```
to get the SDK 1.0.1:
```
git clone https://github.com/hyperledger/fabric-sdk-java.git
cd fabric-sdk-java/
git checkout tags/v1.0.1
```
Now there is a failure in the unit test just because a certificate has expired. If you're not doing development which no one is on v1.0.1 then to run the integration tests :
mvn clean install -DskipITs=true -Dmaven.test.failure.ignore=false javadoc:javadoc -Dtest=IntegrationSuite
```

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=nkRmW7xBreva5TXiB) @rickr @sanchezl Thank you so much and my take away from all your responses - use v1.1 SNAPSHOT. My use case requires me to use fabric-sdk-java to deploy chaincode developed in Go on to IBP hosted environment that is at fabric and fabric-ca v1.0.3. This is the context and I am a fabric-sdk-java newbie - however I am skilled in Go and CLI interactions. As always - there is not much margin with dates or deadlines. I believe using v1.1 SNAPSHOT probably is most future proof and the current code level is at 1.0.0-beta. This is the context. Thanks again and you helped me guide to what I am looking for. Regards.

While querying a chaincode using cli, I could see that orderer reference is not used. The result is returned even if the orderer container is down.
But while using the java sdk , channel.queryByChaincode(...) method, we have to initialize the channel and for that, the orderer has to be added to the channel object.
Is there a means to query the peers, using java sdk even if the orderer is unavailable ?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=wR9vaNSz5QyR8nPnH) @rickr Nope. There's just one SDK and all application transactions go through it.

rickr (Mon, 18 Dec 2017 15:28:47 GMT):
Odd can you use a debugger to narrow down where the sdk is initiating these transactions ? Give a stack trace ? Enable TRACE (use: https://ctrlv.it/)

Maybe first look at the difference between what is happening locally and then when remotely ?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=7zKBacgWToeT5pk5z) @rickr I have a certain logging in my SDK, wherein I track the flow of a transaction.The odd part is that the additonal transaction ID that I see in the committed block, is never seen by my SDK. The only place it is found in my system is in a committed block (received by my blockEvent listener), which breaks a certain parsing logic of mine.
rickr (Mon, 18 Dec 2017 17:13:15 GMT):
_ The odd part is that the additonal transaction ID that I see in the committed block, is never seen by my SDK. _
Don't follow : Do you mean that the SDK client never creates this? You don't see it on your client at all but then get it with the eventhub ?
chaitanya (Mon, 18 Dec 2017 17:22:45 GMT):
@rickr precisely yes!
rickr (Mon, 18 Dec 2017 17:29:16 GMT):
So you've enabled the SDK at TRACE level. When you start up and get this transaction id you don't see this transaction id anywhere till it's reported by the eventhub ?
chaitanya (Mon, 18 Dec 2017 17:29:58 GMT):
@rickr yes
rickr (Mon, 18 Dec 2017 17:38:22 GMT):
Think you'll have to paste it (https://ctrlv.it/) The SDK log at trace and the same for the peer log at trace. Orderer wouldn't hurt either. Try to have the times between the systems _relatively_ synced.
Tell us what transaction id you think is errant.

I don't really use OSX so I've not encountered that. You'll need to google it some is right now the best I can offer. That library is used for TLS support.
There is another alternative but Jetty ALPN but you'll need to google that too to figure out how to enable.

The integration test create the channel object and the do join peers to the channel. The `real` channel is created/configured with the configtxgen tool

@vijay5378 - the only way would be to build Fabric yourself and enable experimental features. Although I believe that if you pull down the 1.1-preview experimental features are enabled
vijay5378 (Thu, 21 Dec 2017 12:41:56 GMT):
@mastersingh24 I did do that, but with v1.0.5. I didn't use docker images. Would I be able to try out java chaincode if I clone the v1.1.0-preview git branch?
mastersingh24 (Thu, 21 Dec 2017 12:57:40 GMT):
You should be able to just pull down the 1.1.0-preview images as well

https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java
Once network is created :
https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric/sdkintegration/End2endAndBackAgainIT.java
Study them and better yet work with them in a debugger to follow the code ( *a live demo* ) *working code right before eyes!*
Then once you understand them you can cut and paste from there to your own application. ( _the code is done for you!_ 🙂 )

All the integration test can be enabled for TLS and are so for verification tests.
Before starting docker images:
export ORG_HYPERLEDGER_FABRIC_SDKTEST_INTEGRATIONTESTS_TLS=true
export ORG_HYPERLEDGER_FABRIC_SDKTEST_INTEGRATIONTESTS_CA_TLS=--tls.enabled
Before starting the client integration tests:
export ORG_HYPERLEDGER_FABRIC_SDKTEST_INTEGRATIONTESTS_TLS=true
Most likely you certificate is wrong or host/ip in the certifcate CN does not match.

Did you look at the orderer logs ?
docker logs orderer.example.com
enable trace on client see exactly when you send the transaction then look at what's being produced by the Orderer.

This updates a channel if you had a _template_ you could continue to update it but I'm not sure if it will allow you to change the channel name.
The other approach is possibly provide your own wrapper (maybe REST based) around _configtxgen_

This would only work too I think if you could use the same crypto artifacts for the new channels you were creating; otherwise, you also need generate that too via `cryptogen`

If I have a chaincode thats already deployed and running and I need to query the chaincode with a java application - do I need to enrol a new user for this purpose? The java application can be deployed on a mobile or a website - would it not be a very cumbersome process if every installation needs to be enrolled?

Register creates the user identity and gives a password (aka secret) The registrar would give the user that information. After that presumably that user would `enroll` with his own private/public key pair to get a certificate needed to make requests. The `enroll` function will also generate the public/private keys for the user if they're not given.

I can't answer that I don't know you're application. If your application can all use the same user identity then maybe not. If they can't I'd think you would need each mobile /website to have the admin/registrar create their own ID via HFCAClient.register and they have them enroll to persist the certificate and keys.

Did I miss understand what you're looking for ? I assume you're looking to get a signed certificate from the CA (ecert)
From the code rather obvious it first registers a user if needed. The looks if enrolled ( need a certificate from the CA). Does a ca.enroll(..) with user name and secret (gotten from the register)
That returns from the CA a HCAEnrollment. The HCAEnrollement.getCert() returns a CA signed certificate in PEM format.

Hard to tell. Best if you can go into a debugger put a BP right where the error is happening. Go to fabric console where debug msg are being output. Do a couple of enters to mark the spot or clear the terminal. Then single step on the client across this error. On fabric console you should have only what lead up to this error.

@duwenhui Just FYI. https://jira.hyperledger.org/browse/FAB-5709
Orderer of v1.0.0 has a bug in cutting a block caused by the number of transactions or by the size of transactions in a block exceeding a threshold (i.e., not the case of Time-To-Cut). According to the JIRA item, this issue is fixed in v1.0.2. I am not sure this is related to the time out you observed.

@ryokawajp Thanks for your reply, Do you know that 1.0.2 is compatible with version 1.0.0 completely? If so, I just upgraded to the next version 1.0.2 and verify.
ryokawajp (Thu, 11 Jan 2018 08:32:57 GMT):
@duwenhui I do not know very well about the compatibility. AFAIK, 1.0.2 is a bug fix release. A chaincode for v1.0.0 is compatible. For clients, fabric-sdk-java v1.0.1 have been released and this one is compatible with Fabric v1.0.2. For replacing Fabric in an existing network, I only have an experience of the case from v1.0.0 to v1.0.1 and it worked fine. However, channel artifacts files created by configtxgen tool are not compatible. When you create a new channel in v1.0.1, you need to re-create channel artifacts files.

Hi, I am going through on integrating the Chaincode deployed on the "Blockchain instance on IBM cloud" with the "java application sdk". I found few examples, struggling with the user certs/keys to construct the "User/SimpleUser" to get the connectivity to the channel/chaincode. In the "Blockchain instance on IBM cloud", I see the "credentials json" which got various certs for each peer/orders/ca's. So I got confused which one to use, as I see in couple of examples it was mentioned as "xxxx.priv" and I don't see that in that "credentials json". Any help in constructing the "user" and assigning to the "client.setUserContext(user)" is much appreciated. Thanks!

Hi, I have noticed 2 issues while trying to upgrade chaincode using Java SDK,
1.I have not installed/instantiated the chaincode, and I try to upgrade the chaincode, it is giving me the error message as "Sending proposal to peer0.org1.example.com failed because of: gRPC failure=Status{code=UNKNOWN, description=chaincode error (status: 500, message: could not find chaincode with name 'kafkachannel'), cause=null}"
Here, my chaincode name was "Test123", and I have set it correctly. The channel name is "kafkachannel". This is not meaningful as the chaincode name is not "kafkachannel".
2.I have installed the chaincode,but I haven't instantiated the chaincode, and then I try to upgrade the chaincode, it is giving me the same error as earlier: "Sending proposal to peer0.org1.example.com failed because of: gRPC failure=Status{code=UNKNOWN, description=chaincode error (status: 500, message: could not find chaincode with name 'kafkachannel'), cause=null}"
Here also the chaincode name is not meaningful,
Moroever, there is no distinction between the Upgradation errors from Fabric, whether the chaincode is not installed/instantiated?
Can someone please look into this and help me out?
[I am able to upgrade the chaincode after doing the foll:installing and instantiating the chaincode, then again installing with a diff version.]

@ancythomas Have you tried diagnosing the issue ? Turned on logging both SDK and on Fabric ( see README.md) did it give you any insight ? Best technique if you can is set a break point in debugger right before the api that has the issue, clear or do a enters to know in the logging output where the command started. Then put a break point right after and do a run. Should show you only logging for that api.

praveentalari (Sat, 13 Jan 2018 04:55:19 GMT):
even I have that doubt. With the introduction of fabric composer and the support of only javascript chaincode , I wonder if there will be updates for fabric-sdk-java. I think going forward only composer and js chaincode will be supported.
silliman (Sat, 13 Jan 2018 19:54:55 GMT):
@praveentalari the languages supported by SDKs for apps calling chaincode are decoupled from the languages that chaincode themselves run in. So, e.g., the fact that java chaincode is not currently enabled is irrelevant to the future of the java SDK. Additionally, since the core of Hyperledger Fabric is written in Go, I find it highly unlikely that Chaincode in Go would not continue to be supported for the foreseeable future.
diego88 (Sun, 14 Jan 2018 03:41:37 GMT):
Hi, i have a question. On the sdk there is a file called TestConfig.java. Inside there are some properties like
String INTEGRATIONTESTS_ORG =org.hyperledger.fabric.sdktest.integrationtests.org.
and some default properties like:
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.mspid", "Org2MSP");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.domname", "org2.example.com");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.ca_location", "http://localhost:8054");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.peer_locations", "peer0.org2.example.com@grpc://localhost:8051,peer1.org2.example.com@grpc://localhost:8056");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.orderer_locations", "orderer.example.com@grpc://localhost:7050");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.eventhub_locations", "peer0.org2.example.com@grpc://localhost:8053, peer1.org2.example.com@grpc://localhost:8058");
if i try to run the network with the example i have no issues, but if i run my own network how i have to modify these integrationtest_org?

TestConfig.java Sample* Are not part of the SDK. While the integration test show how to use the SDK they are also our tests and we need to test with multiple orgs peers etc. I really wouldn't expect anyone building an actual application would use these verbatim. If you're just trying to run against a different network that has all these defined EXACTLY like sdk has done then yes you would mostly need to make changes in TestConfig.java

The issue is when I am trying to upgrade chaincode using *sendUpgradeProposal()*
The issues are:-
1. *The response from Fabric SDK is same , even if the chaincode is not installed/instantiated.*
This does not give a proper message to the User.(it could be different to emphasise the exact reason for failure, as "not installed" when it is not installed and "not instantiated" when it is not instantiated)
2. The response from Fabric in both the cases is as:
"Sending proposal to peer0.org1.example.com failed because of: gRPC failure=Status{code=UNKNOWN, description=chaincode error (status: 500, message: could not find chaincode with name *'kafkachannel'*), cause=null}"
Here the chaincode name is wrongly referrring to the channel name. It should have been
_could not find chaincode with name *'Test123'*_

But, when we test it from SOAPUI with URL http:\localhost:7050 with HTTP METHOD GET/POST, we get an error saying ‘- ERROR GETTING RESPONSE; ORG.APACHE.HTTP.NOHTTPRESPONSEEXCEPTION: THE TARGET SERVER FAILED TO RESPOND’.
Need your inputs on how this can be rectified to run the Blockchain program? The Blockchain program is successfully registered with the Docker. We got stuck post trying from the URL.
Linked followed for the implementation: https://www.ibm.com/developerworks/library/j-chaincode-for-java-developers/index.html
File – SIMPLESAMPLE.JAVA

Each running CC produces docker instances .. try using docker log command to see if there is any more information. This is a peer endorser issue and you're more likely to find answers in #fabric-peer-endorser-committer channel

for 1.0.1, i was using netty jars of 4.1.8 and the netty-tcnative-boringssl-static-1.1.33.Fork26. They used to work just fine as long as i was deploying in a Tomcat 7.0 version.

I have the following setup - Peer1 in machine 1 (Org a) and peer2 in machine 2 (org 2). I have written a chaincode which functions as a smart contract and I have set the policy for this chaincode as follows AND ('orgs.member','org2.member') as I want both the peers to endorse any transaction.
I have also written a java application that will invoke the chaincode and will add a key, value to the ledger.
Now, how do I go about this ?
Should the java application form a transaction proposal and get endorsements from both peers? If yes, then the application would need the private key from both the peers.
Is this the right approach?

Be warned Latest Fabric master has an issue with very latest SDK IT tests. Fabric committed a feature which the SDK's implemented then changed it and merged that which broke the SDKs. This won't be fixed until https://gerrit.hyperledger.org/r/#/c/16741/ is merged.

You can turn on tracing for the SDK that shows details on what we are sending. I suggest if that looks ok take log information to #fabric-peer-endorser-committer channel and ask them what creator identity they were expecting. If they can't I think thats a worthy of opening a JIRA on that component.

Mostly. The SDK should have the public signing CA cert that the proposals have been signed aka verified when they are received. The only private key needed is the one when the proposal is created that is sent as the user context

rickr (Fri, 19 Jan 2018 18:52:57 GMT):
@hpurmann Your application needs _stay running_ for the events to keep coming in. You need to determine how it will terminate.

Thank you, so I guess a separate thread might be a good option :)
rickr (Fri, 19 Jan 2018 18:55:47 GMT):
Not sure that would really be needed .. If you register that block listener and then do a long sleep in a forever loop that would work too
rickr (Fri, 19 Jan 2018 19:05:00 GMT):
I should have said .. after you initialize the channel you could put that forever loop.

I try to get the payload of the transactions of a block. When I execute
```Common.Block block = blockEvent.getBlock();
BlockData blockData = block.getData();
System.out.println(blockData);
```
I get all of it but completely unstructured. How can I get structure in this? Is this a protobuf message? Do I somehow need to parse it?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=iZiDecDP7WyNdo8dz) @asaningmaxchain @ibmamnt For usual transactions, one of the available orderers added by addOrderer() is used. So it supports multiple orderers. While I realized that a function called Channel.initialize() also accesses an orderer to get a configuration block but it does not support multiple orderers because it calls getRandomOrderer(), as metioned by @asaningmaxchain .
rickr (Mon, 22 Jan 2018 09:16:41 GMT):
Multiple orders can be used to balance workload amoung them. Currently it does not support fail over

I have instantiated a chaincode with -P "AND ('Org1MSP.member','Org2MSp.member')". I am trying to add a key, value to the ledger using the chaincode. Now even when the transaction is endorsed by just one MSP, it still writes to the ledger...am I missing something?
rickr (Mon, 22 Jan 2018 15:16:34 GMT):
Not familiar with ` -P "AND ('Org1MSP.member','Org2MSp.member')".` but if you think it needs endorsing of two org member and it's committing it without that I would take that to the #fabric-peer-endorser-committer channel as they could probably more quickly tell you why.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=WorgpMNigPgXL49Sn) @rickr If that was in response to the AND endorsement question, the answer is yes. Two orgs in a consortium - two CAs and separate peers for each org with AND endorsement required. I think it boils down to the channel only supporting a single HFClient rather than a list (for the list of orgs that are party to the transaction - like the JS code in the corresponding node SDK). I can provide more details but this encapsulates my issue.
rickr (Wed, 24 Jan 2018 15:02:08 GMT):
It's not realistic in a single application you would credentials for both orgs. If you, wanted try this in a single application
.. create a client for org1
create the channel
join the peerOrg1 to the channel.
install CC to peerOrg1
instantiate CC to peerOrg1
.. now _pretend_ you're anther org org2
create a new Client
create new Channel (same name)
join peerOrg2 to the channel
install CC on peerOrg2
(no need to instantiate it done before by org1)
send invoke endorsement proposal to peerOrg1 and peerOrg2
send endorsed proposals to ordererer

It doesn't work.
aatkddny (Wed, 24 Jan 2018 15:16:12 GMT):
It doesn't work. That's kind of my point. When you collect the responses and submit on the channel in the way you describe you get a security exception because the channel doesn't know about the second peer and it's trying to package with the wrong certs.

This is specific to the Java SDK. It works just fine from the CLI

and exactly what are you doing when that occurs
aatkddny (Wed, 24 Jan 2018 15:31:39 GMT):
I'll rerun and post in a few. It comes when you do the sendTransaction(...) to the channel after you aggregate all the successful ProposalResponse responses.
rickr (Wed, 24 Jan 2018 15:32:19 GMT):
Hmm you got then all the correct endorsements
aatkddny (Wed, 24 Jan 2018 15:34:10 GMT):
Of course. The problem (I think) is that the channel wraps with HFClient for Org1 but there are certs for Org2 mixed in there that it doesn't know about and it doesn't like the mismatch.
rickr (Wed, 24 Jan 2018 15:37:30 GMT):
Not understand that. If you have two separate clients how anything like that is possible. When you created client2 you should have set a user context from a user with CA from org2 likewise for org1
aatkddny (Wed, 24 Jan 2018 15:38:03 GMT):
Yes but you submit to the channel. Which has one HFClient in it.
rickr (Wed, 24 Jan 2018 15:38:17 GMT):

When I originally ran this I got all the endorsements. Back in mid December. I haven't run it like this in a long time - we changed the app to require individual endorsements and invoked serially with the orgs.
Now that all worked I wanted to revisit this so I asked if anyone had done it. Now we are on a newer version of Fabric - 1.1.0 iirc and the error has changed. Mea culpa - I should have rerun it before stating that it was failing on the sendTransaction - where I left off. But it ~is~ still failing so my question stands. Has anyone actually managed to do this?

Hi everyone! I have new to fabric and am currently trying out the java-sdk. I am following the Endtoend tutorial on youtube by tuand and got stuck with an error. Would really be grateful if someone can help explain where I got it wrong.
I started running the test as suggested by the video (EndtoendIT) and got caught with this exception.
org.hyperledger.fabric.sdk.exception.EnrollmentException: Failed to enroll user admin
Caused by: org.apache.http.conn.HttpHostConnectException: Connect to localhost:7054 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused (Connection refused)

I also ran docker ps -a to see my running docker images, and true enough, the CA is not running
The docker-compose.yml file does include a CA and I can't figure out why.
Did anyone encounter the same problem?

@rickr Can you please suggest
rickr (Tue, 30 Jan 2018 20:15:47 GMT):
most likely case is your certificate is not matching hostname
rickr (Tue, 30 Jan 2018 20:16:27 GMT):
or wrong certificate
ManjeetGambhir (Tue, 30 Jan 2018 20:20:00 GMT):
what should be the cert type ?
ManjeetGambhir (Tue, 30 Jan 2018 20:20:15 GMT):
Cert or Orderer?
ManjeetGambhir (Tue, 30 Jan 2018 20:20:26 GMT):
Cert of Orderer?**
ManjeetGambhir (Tue, 30 Jan 2018 20:21:50 GMT):
or certificate of Authorized member of Channel
rickr (Tue, 30 Jan 2018 20:23:08 GMT):
If you're connecting to the correct url and tls negotiation is failing the only thing I can think off the bat is your certificate
```
ordererProperties.setProperty("pemFile", "Tried with PEM File Location for Orderer Pem File ");
```

Hi Rick , one quick question , in application code we are fetching peer object from channel but over there there is no way to set PEM file {grpc.NettyChannelBuilderOption.keepAliveWithoutCalls=[Ljava.lang.Object;@270d54ea, negotiationType=TLS, grpc.NettyChannelBuilderOption.keepAliveTimeout=[Ljava.lang.Object;@4c0ac628, grpc.NettyChannelBuilderOption.maxInboundMessageSize=99999999, sslProvider=openSSL, hostnameOverride=peer0, grpc.NettyChannelBuilderOption.keepAliveTime=[Ljava.lang.Object;@78363803}
ManjeetGambhir (Tue, 30 Jan 2018 23:05:13 GMT):
Can you please suggest how to do that ..Call is failing in blockchainInfo = channel.queryBlockchainInfo(peer);
ManjeetGambhir (Tue, 30 Jan 2018 23:05:20 GMT):
with SSL error
rickr (Tue, 30 Jan 2018 23:15:28 GMT):
I don't follow the issue. When you create the Peer from the client you can give it any connections properties the same for the orderer
ManjeetGambhir (Tue, 30 Jan 2018 23:27:48 GMT):
resolved it ..

@rickr which crypto library java SDK uses?

@rickr is the crypto lib same as described below: https://developer.android.com/reference/java/security/package-summary.html
rickr (Wed, 31 Jan 2018 18:38:09 GMT):
We make use in many cases bouncy castle because JCA?JCE does not cover what we needed. We've tried to minimize but its still present.

HI @rickr! Thanks for your reply. I have another problem now. I have two organisations say org1 and org2 and each of these orgs have 2 peers. I have create a channel name foo using peer0 of org1 and now I am trying to join the peers from both the organisations. But I am getting an error while joining peers of org2.
```java.lang.Exception: io.grpc.StatusRuntimeException: UNKNOWN: Failed to deserialize creator identity, err Expected MSP ID Org2MSP, received Org1MSP

tsnyder (Thu, 01 Feb 2018 16:03:32 GMT):
Using the E2E test code as a pattern, I have written some wrapper code around the java sdk wrapper to instantiate and maintain the channel information. After calling the channel.initialize() function I check the initialized and shutdown flags - they are fine ( true, false). Prior to invoking channel.sendTransaction() I check again and find that the initialized and shutdown flags are ( true, true). Any ideas on why the shutdown flag is subsequently being set to true?
rickr (Thu, 01 Feb 2018 17:48:54 GMT):
@tsnyder I don't see a case of that running the integration tests. I put in additional assert and ran in debugger with bkpts on when the shutdown field changed. Only times I seen was when the channel was explicitly called to shutdown or when it finalized.
rickr (Thu, 01 Feb 2018 17:50:36 GMT):
@zerppen The really is just one orderer as dockercompose only starts one. Just two reference to the same one.

Make sure if you do capture it that name is your channel name .. the sdk sometimes creates system channel under the cover that will finalize .. but should not have your name
rickr (Fri, 02 Feb 2018 20:16:26 GMT):
The only time the SDK I think calls that on it's own is if the channel is finalized

Hi, This is regarding the "Blockchain Instance on Bluemix", in the "Blockchain-GUI".
What is the purpose of the "Certificates tab under Members"?
As I could able to post a transaction or read a transaction from the client connecting to the "Peer" without even uploading the "Client side certificate" on to the "Certificates tab under Members".
So, I am not sure what is the purpose of "Certificates tab under Members". And how is it secure to control the client to Post or Read transactions from Blockchain? Thanks.
rickr (Sun, 04 Feb 2018 18:20:41 GMT):
@albert.lacambra No not really. As the application/SDK you don't know for sure what the endorsement policies are currently. Even if you created the chaincode with a specific endorsement policy there's no quarantine that someone from some other organization has modified it in the interim.

Our integration tests do check for testing purposes - that all proposals we sent got valid endorsements which may be a _little_ misleading. The application should make sure that all returned endorsements are verfied.

albert.lacambra (Sun, 04 Feb 2018 19:08:37 GMT):
wouldn't it be useful to have the possivility to "extract" the current policies, so that they could be verified before to be sent?
albert.lacambra (Sun, 04 Feb 2018 19:10:11 GMT):
how should then the client choose to which peers should be the proposal request sent?
rickr (Sun, 04 Feb 2018 19:18:27 GMT):
Knowing which other organization and peer location is currently _out of bound_ information_. Given you know what they are I would send them to all peers for endorsements. On return, select those endorsements that are successful and verified Send them to the orderer .. let it and the committing peers do their work. The future you get back will fail if there were insufficient endorsements. Or you can monitor the blocks for transactions to see if failed.
albert.lacambra (Sun, 04 Feb 2018 21:21:00 GMT):

There is a way to know anchor peers but not enough information to reliably connect. Today you should assume you need to know that before hand.
There is something planned in the future to do peer discovery

This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add

Hi, getting the below exception. Can anyone help?
krisava (Tue, 06 Feb 2018 17:25:17 GMT):
UNIMPLEMENTED: unknown service protos.Deliver
rickr (Tue, 06 Feb 2018 19:26:31 GMT):
most likely this https://github.com/hyperledger/fabric-sdk-java/blob/master/docs/release_v1.1.0_notes.md#fabric-v10-considerations

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=pdi3GkGPrzqBHFQLX) @rickr Looks like, as I was not having issues till early this week and just started seeing when I did the maven update. Also, I see compilation issues with respect to the fabric-sdk-java latest update
Channel.setTransactionWaitTime
Channel.setDeployWaitTime
Any idea on how to get this resolved, "UNIMPLEMENTED: unknown service protos.Deliver" issue?
rickr (Tue, 06 Feb 2018 19:32:13 GMT):
remove them
krisava (Tue, 06 Feb 2018 19:33:52 GMT):
yes, I have commented them. but still I get this error "UNIMPLEMENTED: unknown service protos.Deliver".
rickr (Tue, 06 Feb 2018 19:34:36 GMT):
most like your using the v1.1 client against a v1.0.x fabric

Hi @rickr ,
This is regarding the implementation of Network Profile in fabric-sdk-java mentioned in JIRA "https://jira.hyperledger.org/browse/FAB-5632".
As per the JIRA the fix version for this is v1.2, and also it is NOT mentioned as one of the release features for fabric v1.1.0-alpha at: https://github.com/hyperledger/fabric/releases/tag/v1.1.0-alpha
However, if I pull the source of fabric-sdk-java with tag "v1.1.0-alpha", I could see that Network Profile is implemented in class "org.hyperledger.fabric.sdk.NetworkConfig".
Also, there is a reference implementation in tests at: src\test\java\org\hyperledger\fabric\sdkintegration\NetworkConfigIT.java
Request you to please clarify, if this feature is available for use for fabric-sdk-java on v1.1.0-alpha?

When i check on the java SDK side with the peerAdmin context, all is fine. Do I really need to do all theses steps from the Java SDK and not from the Kubernetes scripts using the CLI ?

Yes - you need to use the network that those tests expect

I got these ports already in my virtual box

That's not enough you 'll find what you need in the vagrant session. As stated before. Take the time to read the READM.md once *fully*. Then read it again :) Will go a long way to helping you.

rickr (Fri, 16 Feb 2018 14:59:19 GMT):
But ports I don't think are your problem
huy.tranibm (Fri, 16 Feb 2018 17:26:04 GMT):
Has joined the channel.
huy.tranibm (Fri, 16 Feb 2018 17:29:58 GMT):
Hello Friends: I am running the 1.1alpha e2e test. Before i ran the test, inside of test.fixture.sdkintegration.docker-compose.yaml for ca0, i had to remove both
```${V11_IDENTITIES_ALLOWREMOVE} ${V11_AFFILIATIONS_ALLOWREMOVE}```
from the command as it wasn't recognized.
Second, after i ran the End2endIT.java test, i was successful for all of channel foo's operation but when i got to channel bar's operation things started failing. I've noticed in the readme.md of the fabric java sdk git it says : ```End to end test environment
The test defines one Fabric orderer and two organizations (peerOrg1, peerOrg2), each of which has 2 peers, one fabric-ca service.```. and when checking the logs, for channel bar, its using a fabric ca for org2

huy.tranibm (Fri, 16 Feb 2018 17:37:13 GMT):
@mujji89 inside of the docker-compose.yaml you need to get rid of ```${V11_IDENTITIES_ALLOWREMOVE} ${V11_AFFILIATIONS_ALLOWREMOVE}``` as that is what's causing your ca0 not to run. Im not sure why that is there can someone here explain?
jeffguo (Fri, 16 Feb 2018 17:37:38 GMT):
Has joined the channel.
jeffguo (Fri, 16 Feb 2018 18:24:46 GMT):
in the java sdk, is there an asset registry concept similar to composer?
rickr (Fri, 16 Feb 2018 18:34:31 GMT):
No persistence.
mujji89 (Fri, 16 Feb 2018 19:53:53 GMT):

how many orgs, peers, ca are you running?
rickr (Fri, 16 Feb 2018 19:56:09 GMT):
My gut feel is you're not running the docker-compose that's provide by the SDK
mujji89 (Fri, 16 Feb 2018 19:56:22 GMT):
default config, I am running first time. I think its 1 ca and 2 peers

can you point us to the repo you are bringing up your network?
rickr (Fri, 16 Feb 2018 19:58:27 GMT):
for the Integration test the SDK provides you need have this
https://github.com/hyperledger/fabric-sdk-java/blob/09776f0610193982cdee6ec8e00d5244bb82e65d/src/test/fixture/sdkintegration/docker-compose.yaml

mujj, are you failing on the test for channel foo or bar?
mujji89 (Fri, 16 Feb 2018 20:14:12 GMT):
where can I check that
huy.tranibm (Fri, 16 Feb 2018 20:15:01 GMT):
for the e2e test, it test first with channel foo then bar, you can see this from lines 242-270 in the End2endIT.java
huy.tranibm (Fri, 16 Feb 2018 20:16:25 GMT):
can you comment outlines 254-269(commenting out the test for channel bar), restart your networking using ./fabric.sh down, then clean then up again
huy.tranibm (Fri, 16 Feb 2018 20:17:17 GMT):
ensure that inside of your network-config.yaml has the correct credentials for org1( by default it should)
huy.tranibm (Fri, 16 Feb 2018 20:21:23 GMT):
everytime you run the test make sure you take down your network, as the user your trying to register is already registered and the ca will reject(had you ran the test already)
mujji89 (Fri, 16 Feb 2018 20:22:43 GMT):
HFCAInfo info = ca.info(); //just check if we connect at all.
mujji89 (Fri, 16 Feb 2018 20:22:53 GMT):
this is where it's breaking
mujji89 (Fri, 16 Feb 2018 20:23:17 GMT):
ok I will check
huy.tranibm (Fri, 16 Feb 2018 20:24:16 GMT):
i also just realized that you are running a windows and i won't know too much about the differences as i am on a mac
mujji89 (Fri, 16 Feb 2018 20:24:47 GMT):
Yes, sadly I am on windows
huy.tranibm (Fri, 16 Feb 2018 20:25:15 GMT):
i was able to get both channel foo and bar working(foo for org1 and bar for org2) but i had to run them separately
huy.tranibm (Fri, 16 Feb 2018 20:25:48 GMT):
at line 690&691, i had to edit that also
huy.tranibm (Fri, 16 Feb 2018 20:26:07 GMT):
so line 690 for channel foo, and 691 for channel bar
huy.tranibm (Fri, 16 Feb 2018 20:26:21 GMT):
and my network-config.yaml i replaced the org1 credentials with org2
huy.tranibm (Fri, 16 Feb 2018 22:10:14 GMT):
@mujji89 hey i was able to reproduced your error at HFCAInfo info = ca.info(); //just check if we connect at all.
huy.tranibm (Fri, 16 Feb 2018 22:10:29 GMT):
are you using testutils.properties?
mujji89 (Fri, 16 Feb 2018 22:44:45 GMT):
Hi, I did nothing on that, so I assume no
huy.tranibm (Fri, 16 Feb 2018 22:49:52 GMT):
ok nvm
mujji89 (Fri, 16 Feb 2018 22:51:39 GMT):
how were you able to reproduce?
huy.tranibm (Fri, 16 Feb 2018 22:52:14 GMT):
i accidently included the tls properties into the testutils.properties and set the value at null
huy.tranibm (Fri, 16 Feb 2018 22:52:25 GMT):
and it gave me the same error, but after removing it, it worked
mujji89 (Fri, 16 Feb 2018 22:53:48 GMT):
where do you have testutils.properties?
huy.tranibm (Fri, 16 Feb 2018 22:54:27 GMT):
i created it into test.java.org.hyperledger.fabric.sdk
huy.tranibm (Fri, 16 Feb 2018 22:54:42 GMT):
using the default values provided by TestConfig.java
mujji89 (Fri, 16 Feb 2018 22:58:05 GMT):
I don't have testutils.properties

Hi guys, when i run the network from the test.java.sdk fabric.sh, am I running peers version 1.1 alpha or 1.0.5?
schwinnez (Sat, 17 Feb 2018 15:21:21 GMT):
Hi,
I am trying to install chaincode as in https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java via Java-SDK.
Looks like installation works fine... but i can not find the chaincode in the filesystem after installation and instantiation of chaincode fails for the same reason ("...can't load package: package [CHAIN_CODE_PATH] ..."). I am having the chaincode in resources of my java project.
schwinnez (Sat, 17 Feb 2018 15:27:44 GMT):
(according to the peer logs, the peer is looking for chaincode in /chaincode/input/src/vgmchain/chaincode/[CHAINCODE_PATH] I also don't understand why it is looking there. There is even no /chaincode directory...) Any ideas?
rickr (Sat, 17 Feb 2018 15:47:30 GMT):
During install chaincode is sent to the peer you should see it there in `/var/hyperledger/production/chaincodes/'`
rickr (Sat, 17 Feb 2018 15:49:48 GMT):
I'm thinking your packaging of the chaincode and chaincode path specified is off. Double check to make sure it's similar to what's done in the integration tests.
M4rcelNo4ck (Sat, 17 Feb 2018 18:06:03 GMT):
Has joined the channel.
schwinnez (Sat, 17 Feb 2018 18:55:29 GMT):
checked it again but so far I didn't spot any major differences.

Hi guys I am back again I fixed previous errors but now I am getting this error while running End2endIT test

the foo test passes but has problem with bar
schwinnez (Sat, 17 Feb 2018 21:47:55 GMT):
okay i got a little further. The problem now is, that it looks like hyperledger fabric go libs are not installed on my peer. I am using the same docker images as for the integration test. Where should the hyperledger fabric libs be located?
schwinnez (Sat, 17 Feb 2018 21:47:55 GMT):
okay i got a little further. A refactoring changed a dependency of my chaincode :unamused: mea culpa. But the instantiation is still not getting through. I get the following error from the peer: {"message":"oci runtime error: container_linux.go:295: starting container process caused \"exec: \\\"chaincode\\\": executable file not found in $PATH\"\n"}
I found, that this might be due to a missing chaincode dependency. But I am using only the following which are quite common:
` import (
"bytes"
"encoding/json"
"fmt"
"time"
"github.com/hyperledger/fabric/core/chaincode/shim"
sc "github.com/hyperledger/fabric/protos/peer"

Hi @rickr, I ran successfully your integration test with the fabric v1.1.0-alpha network
bfuentes@fr.ibm.com (Mon, 19 Feb 2018 10:15:07 GMT):
It seems "configtxlator" from your docker-compose file is not existing in the fabric-tools image on the V1.0.0 and it throws an error

Has joined the channel.
rickr (Mon, 19 Feb 2018 12:13:41 GMT):
yes that was added later. You running I think with sdk v1.1 integration test with a docker-compose that v 1.0 level
rickr (Mon, 19 Feb 2018 12:22:20 GMT):
@chaitanya You shouldn't just replace the SDK jar it probably had other dependencies jar updates. That said, not sure its the problem here. First thoughts is the sdk is sending the invoke so it looks to be on the fabric side failing the chaincode. Have you looked at the chaincode docker instance logs ? Maybe something there. BTW latest fabric release is v1.0.5
chaitanya (Mon, 19 Feb 2018 12:23:40 GMT):
@rickr sure. The chaincode logs do not show any errrors, and the containers stay up after having instantiated chaincodes. It is the peer container which shows the above logs
rickr (Mon, 19 Feb 2018 12:27:07 GMT):
So the chaincode itself executed ok .. you have some log info in your CC that prints that out I assume. Does this happen on all invokes ? You probably need to take this to the #fabric-peer-endorser-committer channel for them to understand what's going on first .. not saying it's not an sdk issue but need to know why that's happening.
rickr (Mon, 19 Feb 2018 12:29:40 GMT):
BTW the most likely thing they'll ask is to be on the latest :wink:
rickr (Mon, 19 Feb 2018 12:32:00 GMT):
Make sure you have some log statement at the very end of your CC after all is done that states ending successfully. Something here seem to me it's not.

dave.enyeart (Tue, 20 Feb 2018 16:45:44 GMT):
@muralisr @jimthematrix @mastersingh24 When node chaincode is packaged into a tar it is packaged under a "src" directory. This is not typical for node.js in general. Is there any reason we had to automatically inject this "src" directory? Or could we remove it? That would help with the packaging that @rickr is looking at, as part of packaging up chaincode indexes during chaincode install step. ( @rickr was suggesting that user could add the src directory when they author node chaincode, but that is messy, I'd rather do away with src directory if possible for node chaincode).

you can also use the image that is generated directly , it is published on dockerhub
jimthematrix (Tue, 20 Feb 2018 17:00:51 GMT):
@dave.enyeart I can't remember a specific reason for the `src` root folder structure, might have just been a random decision to make the content checking logic (for illegal files by extension and permissions) on the peer side easier
jimthematrix (Tue, 20 Feb 2018 17:00:51 GMT):
@dave.enyeart I can't remember a specific reason for the `src` root folder structure, might have just been a random decision to make the content checking logic (for illegal files by extension and permissions) on the peer side easier to implement
jimthematrix (Tue, 20 Feb 2018 17:01:34 GMT):
in fact I think that was the only reason for the src folder
mastersingh24 (Tue, 20 Feb 2018 17:55:23 GMT):
@dave.enyeart @rickr - I think we can remove the src folder ;)
rickr (Tue, 20 Feb 2018 18:52:24 GMT):
@mastersingh24 read that to mean we should remove the need for the tar ball to have the `src` directory .. which would mean a change on the Peer
rickr (Tue, 20 Feb 2018 18:54:22 GMT):
Isn't this as easy as if node then md src and untar in src
mastersingh24 (Tue, 20 Feb 2018 19:09:51 GMT):
We don't need to do anything on the peer actually
muralisr (Tue, 20 Feb 2018 19:09:57 GMT):
@dave.enyeart I can't think of a reason for packaging under src/ for node either
mastersingh24 (Tue, 20 Feb 2018 19:10:35 GMT):
We can double check, but I'm not sure why we would need to change the peer

dave.enyeart (Wed, 21 Feb 2018 13:32:15 GMT):
@rickr I looked deeper into node chaincode docker creation. The “src” directory is used to ensure that nothing besides the intended source code gets included in the ultimate chaincode image, only the content under src gets copied:
https://github.com/hyperledger/fabric/blob/master/core/chaincode/platforms/node/platform.go#L187
META-INF and anything else that may be lingering at the top level of the package therefore get excluded from the chaincode image, as desired.
I think we need to keep the package contract as it is, and follow the existing design as mentioned in the FAB-8345 comment (separate src and META-INF directories in the chaincode package.
I think your idea of asking application for a src location and a META-INF location is a good solution.

rickr (Wed, 21 Feb 2018 13:41:42 GMT):
@dave.enyeart Where in Fabric documentation is the META-INF directory layout described ? What needs to be there and what exact format for CouchDB indices ?
dave.enyeart (Wed, 21 Feb 2018 13:43:31 GMT):
@rickr Here it is:
dave.enyeart (Wed, 21 Feb 2018 13:43:31 GMT):
http://hyperledger-fabric.readthedocs.io/en/master/couchdb_as_state_database.html#using-couchdb-from-chaincode
rickr (Wed, 21 Feb 2018 13:44:08 GMT):
To be clear too. We will package this directory but not care what's in it. SDKs will not inspect what's there
dave.enyeart (Wed, 21 Feb 2018 13:44:47 GMT):
right, we do validation of the META-INF content on the peer side. chaincode install will fail if bad content is passed in.
rickr (Wed, 21 Feb 2018 13:52:36 GMT):
why not PEER-INF ? :)

schwinnez (Wed, 21 Feb 2018 17:23:42 GMT):
In case anyone is interested. The problem i was talking about a few days ago comes from some go dependencies. The strange thing is, it only appears when intalling chaincode via Java-SDK. Could this be a bug. And how can I use the go dependencies described there? I think they are pretty basic and it should work in general, right?
https://stackoverflow.com/questions/48852755/oci-runtimer-error-when-installing-hyperledger-chaincode-via-java-sdk
rickr (Wed, 21 Feb 2018 18:33:28 GMT):
Related to this maybe ? https://github.com/hyperledger/fabric-sdk-java#go-lang-chaincode
schwinnez (Wed, 21 Feb 2018 19:46:25 GMT):
But can you explain, why this problem only occurrs when deploying chaincode via sdk? They use the same peer api, i think?
rickr (Wed, 21 Feb 2018 20:10:41 GMT):
they?
schwinnez (Wed, 21 Feb 2018 20:37:54 GMT):
sorry, i mean the cli peer tool and the java sdk.
rickr (Wed, 21 Feb 2018 21:54:11 GMT):
@muralisr ^^^
muralisr (Wed, 21 Feb 2018 21:56:43 GMT):
so if I understand it right @rickr @schwinnez ... the only non-GO packages are ```
"github.com/hyperledger/fabric/core/chaincode/shim"
"github.com/hyperledger/fabric/protos/peer"```
muralisr (Wed, 21 Feb 2018 21:59:46 GMT):
these are already in ccenv and hence don't need to be provided
muralisr (Wed, 21 Feb 2018 22:01:37 GMT):
pretty much what example02 uses
muralisr (Wed, 21 Feb 2018 22:02:48 GMT):
sure that would have worked with java SDK too ? ... not sure what you are running into @schwinnez ...the stack overflow just says ` {"message":"oci runtime error: container_linux.go:295: starting container process caused \"exec: \\\"chaincode\\\": executable file not found in $PATH\"\n"}`
muralisr (Wed, 21 Feb 2018 22:02:57 GMT):
perhaps some more infor from the peer logs will help
muralisr (Wed, 21 Feb 2018 22:02:57 GMT):
perhaps some more infor from the peer debug level logs will help
aatkddny (Thu, 22 Feb 2018 03:18:29 GMT):
So i'm just getting back to looking at a piece of channel generation logic using the sdk. I can do the newChannel using the base genesis block I get from running configtxgen no problem. What i can't see is the analog to the peer channel update calls for the anchor peers for each org msp. Do I need them? It seems to be working without them as far as I can tell. If I do actually need them, is there a sample call in the SDK?
schwinnez (Thu, 22 Feb 2018 07:13:48 GMT):
@muralisr if you're installing a chaincode which uses bytes, json and time (i'm not sure which one lead to the problem) and you do the installation/instantiation as in the End2EndIT you should run into the same problem. I tried it on several environments... same result. I am currently doing a workaround. If you can't reproduce this, then I can produce some DEBUG logs for you, okay? You can also have a look at https://stackoverflow.com/questions/47593097/oci-runtime-error-when-sending-hyperledger-fabrics-chaincode-instantiation-requ. In this case, scrypt (i think also a standard go package) caused the problem. In that thread you will have detailed log.

Hi, I want to provide an own CryptoSuite implementation. In order to achieve this, which components do I have to adopt as well? I'm wondering if the configuration transaction of a channel has to be set up in the right way, such that the right hash function is used for example. So which aspects do I have to concern about when providing an own CryptoSuite? I'm thankful for any advice.

The only time I've seen it fail is if you have configured different security providers
rickr (Fri, 23 Feb 2018 11:50:04 GMT):
@nebsterboy The *only* reason I know of to change crypto behavior is to support hardware encryption. I know one group that has done this. There was no need to replace the current crypto implementation but just provide a different java security provider.
rickr (Fri, 23 Feb 2018 11:54:00 GMT):
@SyneBlockChainTeam Here is an example of how two organization would work together on a single channel. It shows each of their own channel
object having peers of the other to do transactions. https://github.com/cr22rc/fabricSDKJavaMultiDomainSample

@rickr we want to include post quantum crypto. If i'm right, this can bei done by providing a new CrypoSuite. Do you agree?
rickr (Fri, 23 Feb 2018 12:10:38 GMT):
I don't know enough about quantum crypto to answer that. If it has a java security provider implementation I'd try that.
rickr (Fri, 23 Feb 2018 12:10:38 GMT):
I don't know enough about quantum crypto to answer that. If it has a java security provider implementation I'd try that.
Currently the encryption signing is done with elliptical curve and specific strength. This is what fabric and fabric ca expect.
They need to work together. If quantum crypto doesn't do that you'd also need to change Fabric and Fabric ca to use quantum crypto ( my gut feis it doesn't ) I think that would be quite a bit of undertaking.

Hi @rickr,
I Installed chaincode on cloud environment(AWS EC2 instance), using fabric-sdk-java default test network at fabric-sdk-java/src/test/fixture/sdkintegration/docker-compose.yaml
The End2endIT.java tests ran fine within this cloud environment.
However, when from my local laptop i tried to run the End2endAndBackAgainIT.java tests, connecting to this remote blockchain network at AWS EC2 instance got the below error:
Any idea why these errors only in case of remote connectivity from local fabric-sdk-java client to the remote blockchain network at AWS EC2 instance? I have checked connectivity, and all the necessary ports are opened in the remote cloud AWS EC2 instance.

so I followed IBM's aricle ont he same : https://www.ibm.com/developerworks/cloud/library/cl-add-an-organization-to-your-hyperledger-fabric-blockchain/index.html,
but its showing me to go to a peer docker container, and run some commands to get configuration
from peer container itself
, but I have to setup the environment on dev mode, so each peer has to be on different VM, and thet dont have access to other VMs peers,
how to configure a new peer in that scenerio.
It would be of great help if anyone has tried something of this sort

I have not read that article yet and not sure I understand your question. There is a much more basic example of how this is done by changing the channel batch size in the JSDK. Yes it's much simpler undertaking :)
It dependents on previous integration test End2endIT to have run before it that already _created_ the channel and joined the peers. It first reconstructs the object of the channel so the SDK can work with it and the goes through the steps of updating the batch size with the configtxlator

No, I have only done exactly the steps as they are described at
https://github.com/hyperledger/fabric-sdk-java/blob/master/docs/EclipseSetup.md
This is my first time trying to use fabric java sdk.
I just tried to do "Run As> Maven Generate Sources" and "Debug As> Maven Generate Sources" on eclipse and I get "build failed".
I discovered that the problem is caused by the fact that from bash I run "mvn test" as SU / Root, while on Eclipse I do not and therefore I get the following error:
fabric-sdk-java/target/protoc-dependencies/d5e526ad09e0fad2f6c8a7f40d8bcab5/google/protobuf/struct.proto unable to be deleted. -> [Help 1]
I understood this because if I write in the bash "mvn test" without using "sudo" or "sudo su", I get the same error
How can I solve this?

Did you do a maven>generate sources?
huy.tranibm (Tue, 27 Feb 2018 17:57:41 GMT):
For version 1.1 alpha, will the SDK automatically detect TSL from https and grpcs and use the tlsCaCerts property in the config file?
huy.tranibm (Tue, 27 Feb 2018 18:06:48 GMT):
or do i have to setProperties sslProvider and negotiationType manually?
aatkddny (Tue, 27 Feb 2018 18:55:40 GMT):
it fails without the openssl one for sure. not sure about detecting tls - i just set everything.
rickr (Tue, 27 Feb 2018 18:58:47 GMT):
It runs with tls enabled in our IT tests

I tried to do it but unfortunately the problem was not solved

No, I have only done exactly the steps as they are described at
https://github.com/hyperledger/fabric-sdk-java/blob/master/docs/EclipseSetup.md
This is my first time trying to use fabric java sdk.
I just tried to do "Run As> Maven Generate Sources" and "Debug As> Maven Generate Sources" on eclipse and I get "build failed".
I discovered that the problem is caused by the fact that from bash I run "mvn test" as SU / Root, while on Eclipse I do not and therefore I get the following error:
fabric-sdk-java/target/protoc-dependencies/d5e526ad09e0fad2f6c8a7f40d8bcab5/google/protobuf/struct.proto unable to be deleted. -> [Help 1]
I understood this because if I write in the bash "mvn test" without using "sudo" or "sudo su", I get the same error
How can I solve this?

So I'll confess to a basic lack of understanding - something - here.
I'm trying to do this: `BASE_CRYPTO=/crypto-config
ORDERER_CA=${BASE_CRYPTO}/ordererOrganizations/orderer.com/orderers/orderer.orderer.com/msp/tlscacerts/tlsca.orderer.com-cert.pem
CORE_PEER_LOCALMSPID="OrdererMSP"
CORE_PEER_TLS_ROOTCERT_FILE=$ORDERER_CA
CORE_PEER_MSPCONFIGPATH=${BASE_CRYPTO}/ordererOrganizations/orderer.com/users/Admin@orderer.com/msp
peer channel fetch config sys_config_block.pb -o orderer:7050 -c testchainid --tls --cafile $ORDERER_CA`
using the SDK. It fetches the system channel config block.
I'm having terrible trouble getting the peer - any peer - to join the system channel. I've tried just about every combination of parameters of joinPeer and addPeer I can think of. I've created a new peer org with the certs for the organizer and tried using that. I set up a user with the org enrolled using the same code i use to create a peer admin. Same code works to create and join any other channel. What am I missing? I can see the block is there if I step through the code in channel.java. It fails pretty much in the same spot no matter what - looking at the responses in sendProposalToPeers.
I ripped off the code from UpdateChannelIT to act as the base. It works for anything but getting the "testchainid" channel. Is there a trick I'm missing?

rickr (Wed, 28 Feb 2018 14:02:34 GMT):
Peers don't join any system channel. The code from UpdateChannelIT is updating the "foo" channel. You should join peers to channels you or some other organization is created for you.
rickr (Wed, 28 Feb 2018 14:03:51 GMT):
You should update channels you've created or again some other Org created for you to collaborate on.

Are you trying to update an existing channel ?

Or just have that new org in the consortium when you create new channels ?
rickr (Wed, 28 Feb 2018 16:19:02 GMT):
Updating the `orderer system channel` may have issues and need to look into it. However if you are trying to update an existing channel updating the `orderer system channel` will have no affect on any existing channels. You will need to update that specific channel. Loosely, think of it as the channel get's it's own copy of `orderer system channel` information when it's created.

I added the new org to the consortium so I can create new channels for it. Privacy concerns restrict my application to channels between pairs of orgs. New customers need to be integrated into the consortium and have transaction channels created. I have the code to create a channel down pat - I just needed to get them into the list.

The instructions in the link I added work just fine, so I need a way to duplicate the two peer calls from the CLI inside the SDK.
I already did a different piece of code to add an extant org to an extant channel - I ripped it off the UpdateChannelIT. That was fine - I had a peer to come in from.

Hey,
I justrealized, that when using `channel.addPeer(peer)` without specifying the peer options, that peer is given all peer roles. Especially when calling channel.initialize(), this will fail if added peer is not available yet (i think due to added eventing). I am wondering now, what roles should external peers have (if the should endorse chaincode) but i don't want something to fail, i.e. i don't want exceptions when peers are not available. In general, my question is, what channel operations assume peers to be availlable and what can savely be used even when one or the other is not available?

rickr (Sat, 03 Mar 2018 14:55:03 GMT):
You've probably hit something we need to address in the initialize. The issue with having endorsing peers with no event listening for when the transaction is committed is that you'd need to deal with inconsistent endorsements. If the peer you are listening on has committed the block with the transaction and you then send a new proposals to all peers they may not have committed the previous transaction and you'd get inconsistent endorsements. The SDK checks for that by default when you submit to the orderer but even if it didn't it would get rejected by all the committing peers .
schwinnez (Sat, 03 Mar 2018 18:37:21 GMT):
This means it should not happen that it get an exception when a peer is not available?

@schwinnez With out a single peer active there is no way to get the config block which has the certificate CAs to validate endorsements. Also there is no way to do any endorsements either. The SDK probably only right now looks for one then fails, something that should be addressed soon. If initialize and asked that a peer should be doing eventing but it's not available to do I think it's reasonable to not start the channel. Note that after the channel starts if eventing source do become unavailable the SDK continues to trying to connect to it till it does become available. I suppose another option would be to let the channel intiailze anyway and try to continue connect from the start.

I think it will be great if the SDK allows me to add peers to the channel although some of them are not available and perform the peer availability checking internally. I add 4 peers to the channel when endorsement from 2 peers are required because some of them may be down a that time.

Thanks Rick, I'll look at it today. I've been distracted by an ongoing power outage for the last few days.

Thanks Rick, I'll look at it today. I've been distracted by an ongoing power outage for the last few days. I'm assuming the green highlighted lines in the block above are the magic that makes this all happen here - the rest of the code is very similar to the stuff I was trying, albeit with an older configtx - mine doesn't have the Capabilities stuff in it - it looks like I need samples at rc1 to get this.

Actually, the reason this is coming up now, is that for the other projects we are moving to naming scheme like `release-1.0` and `release-1.1` for the maintenance branches. Can we do the same for fabric-sdk-java?

rickr (Fri, 09 Mar 2018 13:25:23 GMT):
@dave.enyeart Don't see a need for `release` When we do decide to do maintenance for a release I can see a `release-1.0` and a `release-1.1` maintenance branch stream created from the tags we have for them on the development master stream. Not sure why those are needed at this time.

dave.enyeart (Fri, 09 Mar 2018 13:30:28 GMT):
@rickr I see two reasons why the release branches are needed:
1) If you need to check-in a fix for 1.0.x or 1.1.x, it will need to be checked in on top of the last 1.0.x or 1.1.x commit.
2) CI for fabric release-1.0 does e2e tests using the SDKs. For this CI, it should utilize SDKs at the same release-1.0 level.

schwinnez (Sat, 10 Mar 2018 12:44:51 GMT):
Hi again, I just want to go into this eventing thing again, which assumes all peers to be available on channel#instantiate time.
In my application, I am maintaining many channels, say around 50, which 50 external organisation. If I only have one endorsing peer per external organisation and I restart my application (for whatever reason), I would need all 50 external peers to be available. Of course, this is very hard to guarantee and the operations of my application would not be an easy task. Since the peers are external to my application, I even have no influence on them. So the only workaround I can see now, is to change my endorsement policy (currently states one of my peers AND one of the other orgs peer) to an OR-policy and just ignore external peers. But this can't be in the sense of hyperledge right? The AND policy is much more what fits my use case and OR esentially means that I am not using endorsement feature at all. How do you think about this?

Hi again, I just want to go into this eventing thing again, which assumes all peers to be available on channel#initialize time.
In my application, I am maintaining many channels, say around 50, with 50 external organisations. If I only have one endorsing peer per external organisation and I restart my application (for whatever reason), I would need all 50 external peers to be available. Of course, this is very hard to guarantee and the operations of my application would not be an easy task. Since the peers are external to my application, I even have no influence on them. So the only workaround I can see now, is to change my endorsement policy (currently states one of my peers AND one of the other orgs peer) to an OR-policy and just ignore external peers. But this can't be in the sense of hyperledge right? The AND policy is much more what fits my use case and OR esentially means that I am not using endorsement feature at all. How do you think about this?

Of the bat I don't know of any commit time. Each committing peer writes to it's own ledger so when it's written could be different

@kiattchaip Methods that explicitly supply the user context should work fine on different threads. If there is no need to change the user context on the client all methods should also work too.

@rickr what does channel.sendTransaction(successful).get(testConfig.getTransactionWaitTime(), TimeUnit.SECONDS) returns? Our usecase: We want to submit multiple transactions from clients to load test our system. Issue is if we use "channel.sendTransaction(successful).get(testConfig.getTransactionWaitTime(), TimeUnit.SECONDS)" it only returns after the block is generated (only includes 1 transaction in block). If we only use channel.sendTransaction(successful) and continue sending more transactions in a loop, we get BAD_REQUEST from the order. What we are doing: setup: 4 peer, 4 org, 1 orderer with kafka, each org on peer! Client side: 4 threads, each thread pushes 50 transactions and each thread pushes transactions on a different org.

Sending many `sendTransaction` _should_ work. You'd need to take that first to the #fabric-orderer channel with logs and details to help out why it's not working.

rickr (Mon, 12 Mar 2018 12:34:51 GMT):
@schwinnez I thought I mentioned that's being _reworked_. The plan is to have it initialize without peers being available. The eventing services already once started would continue to try and reconnect. That said, when you send a transaction to Orderer and you want to know when it completed if the eventing services is not available the future if you specified a timeout will .. timeout. At that point your application will either accept that or go into some recovery mode that does queries (queryBlockByTransactionID) to all the peers that are important to find what the true state of whether that transaction got successfully committed. Take note that eventhubs and peer eventing service are actually on the peer it'self too, so there's a fair chance those will fail too.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=AyJgKPopougZXqJaq) @rickr Okay, sorry I thought you mean, that you are reworking only that it works when they loose their connection but that connection still needs to be available at #initialize time. So this sounds good to me =). Will it come with the 1.1 release or do you plan to include the change later? Regarding your remark: Wouldn't it be okay to be "optmistic" about the commitment? I mean, If everything is fine with that transaction and I got the endorsement, eventually it should be commited by every committing peer? Of course, if I do a transaction that changes uncommitted keys, I could have inconsistend RW-Sets. What to you think is the best practise to handle this in the application? Optimistic (is eventing then necessary?) or handlig explicitly?

@darapich92 If you want to use the SDK, you don't need to run it in your eclipse. Just create a new maven project and add the SDK dependency. The src/test/java/org/hyperledger/fabric/integration/End2endIT.java in the source that you clone from the github can be use as an example of how to you the SDK.

kiattchaip (Tue, 13 Mar 2018 06:48:10 GMT):
@darapich92 I think you misunderstand about the SDK. It is not for building a network. You have to build a fabric network first. The SDK is just a tool that helps you to interact with the fabric network such as install a chaincode, send a transaction and query data. It acts like the cli in the Building Your First Network tutorial.

I then go through all of the peers for all of the orgs and do a joinPeer (using the peer Admin for that org).
I then do a channel initialize.
It works most of the time. But then sometimes it fails with a proposal exception in getConfigBlock in the initialize.

I have multiple orgs in a consortium and want to create a channel to join three of them. I use the peer admin from one to do the client.newchannel with the channel configuration block and the sigs from all of the orgs - I build an array of getChannelConfigurationSignature signatures for each of the three org peer admins.
I then go through all of the defined peers for all of the orgs and do a joinPeer (swapping in the peer admin for that org into the HFClient) for each. I then put back the original peer admin into the HFClient and do a channel initialize.
It works most of the time, but then it sometimes fails randomly with a proposal exception in getConfigBlock in the initialize. Error is that it has the wrong MSP - it has the original one when it wanted the one for the peer that proposal is going to.
I'm wondering if joining all the channels like this is a mistake - the randomPeer in the initialize is the only thing I can come up with as to why this isn't working. Unless joinPeer is asynchronous and expects the HFClient to always have the admin for the same peer in it.
Ok, I'm grasping at straws, but if doing it this way IS my problem, how am I supposed to create a multi-org channel? If not, any hints as to what I could have messed up.

The constructChannel code in the End2EndIT sample was throwing me off.
I'll enumerate the solution I found for anyone else facing this situation, as it was an unpleasant time sink.
The code sample works for a single org because it does the newChannel with the CCB, followed by the peer joinPeer calls and then the initialize in one go.
If you want to do joins for multiple orgs you must do the newChannel with the CCB for followed by the peer joinPeer calls for all the orgs.
You then build a channel for your org using newChannel(name) and addPeer followed by initialize. You can't do newChannel with the CCB more than once - you get into the "modify a channel to add orgs" stuff that came in with the last go-around of fabric changes.
Caveat: I didn't write any of the underlying SDK. This is observed behaviour. I'm using SDK 1.1.0-alpha against Fabric 1.1.0-rc1. I'm hoping this behaviour hasn't changed.

Apologies that it took me a week to get back to this. I had no power at home and have been stuck looking at a different issue. This all works fine, although I needed to modify my peer create code to account for the different certs.
``` public Map map(String s) throws JsonParseException, JsonMappingException, IOException {
MapType type = TypeFactory.defaultInstance().constructMapType(HashMap.class, String.class, Object.class);
ObjectMapper mapper = new ObjectMapper();
Map result = mapper.readValue(s, type);
return result;
}
```
``` Map x = (Map) map(resultAsString).get("channel_group");
Map x1 = (Map) x.get("groups");
Map x2 = (Map) x1.get("Consortiums");
Map x3 = (Map) x2.get("groups");
Map x4 = (Map) x3.get("YOURCONSORTIUM");
Map x5 = (Map) x4.get("groups");
x5.put("YOURMSP", updateJson); ````

kelvinzhong (Mon, 19 Mar 2018 10:40:21 GMT):
@rickr hi, when i cloned the fabric-sdk-java into idea, there are plenty of errors, because idea default have not protobuf plugin support. I think it might be better to have a simple tutorial about protobuf config in READ ME for the people who new to the project.

@dushyantbehl Yes, but it may not have all the enablement for all the features in latest Fabric v1.1.0. For Fabric v1.1.0 I'd highly recommend if using the SDK get the latest. If using in an application use 1.1.0-SNAPSHOT. These are now _feature complete_ .

They never worked. The closest equivalent for transaction wait time set a time out on the get of the Future returned by sendTransaction . For setDeployWaitTime see Config.java see PROPOSAL_WAIT_TIME
schwinnez (Mon, 19 Mar 2018 19:33:39 GMT):
I just realized, that in my channel and orderer configuration, there is no information about anchor peers at all. I had a look into the configurations and genesis block and I couldn't find the anchor peer information. I thought, that since i configured it in the config-tx.yaml, that it is contained in the orderer genisis or channel genesis. But the it looks like anchor peers have to be configured separately by configuration updates. Looks like my network is working without the anchor peers. In the End2EndIT, I can not see AnchorPeer Updates as well.
What exactly do I need the anchor peers for? A similar question has been asekd here : https://stackoverflow.com/questions/45632859/what-is-anchor-peer-in-fabric . But i still didn't get what i need the anchors for? What am I missing or what problems might happen without any anchor peer information? What SDK method would I have to use to define Anchor Peers? ConfigUpdate for the channel?
rickr (Mon, 19 Mar 2018 20:51:19 GMT):
The SDK itself does not care about whether a peer is an anchor peer or not. The anchor peers are defined in a config block which the genesis blocks is one. The anchor peers are only there for the Fabric side where they are used to discover other peers between organizations. The SDK can change the channel as described by this:

Question about adding an anchor peer using the SDK. Has anyone done it?
It looks like a channel update, but when I try to decode the anchor peer block using protolator I get: proto: bad wiretype for field common.Config.Sequence: got wiretype 2, want 0
On a whim I tried to just use the tx bytes as an update channel and see this in the orderer log: Rejecting broadcast of config message from 172.18.0.1:46596 because of error: error authorizing update: Update not for correct channel:
I'm obviously missing a step, but wondered if anyone had a sample?
aatkddny (Thu, 22 Mar 2018 01:07:33 GMT):
s
aatkddny (Thu, 22 Mar 2018 01:07:33 GMT):
So to respond to my own question...
The anchor peer block decodes with protolator using common.Envelope rather than common.Config.
The rest of it is like adding a member to the channel but you need to update the channel config json with something more like this:
```
private Map addAnchorPeer(String msp, Map config, Map configJson) {
Map x = (Map) config.get("channel_group");
Map x1 = (Map) x.get("groups");
Map x2 = (Map) x1.get("Application");
Map x3 = (Map) x2.get("groups");
Map x4 = (Map) x3.get(msp);
Map x5 = (Map) x4.get("values");
Map y = (Map) configJson.get("payload");
Map y1 = (Map) y.get("data");

```
If anyone actually has done this then I'd appreciate a second look. This update completes normally and the channel config the second time through appears to reflect the "AnchorPeers" fragment, but I've pretty much hacked it. I'm none too sanguine that it's in the correct place and will work as I would wish it to.

No not at the moment. Gossip is only on the Fabric side and not exposed on the clients. There is work being done for a client side discovery service.

aatkddny (Mon, 26 Mar 2018 14:59:39 GMT):
You need to delete the chaincode containers manually. This will do it - substitute {NETWORK} appropriately - `docker images | awk '{ print $1,$3 }' | grep {NETWORK} | awk '{ print $2}' | xargs -I {} docker rmi -f {}`

Hi, i have question about channel initialization. For example if HF network have 2 orgs that have peers and 1 org with orderer(similar to 'fabric-ca' example), each org have 1 peer. Chaincode is installed with AND policy. When adding new peer to channel object, do we need to add peers from both orgs? For ex like:
channel.addPeer(peer from org1)
channel.addPeer(peer from org2)
If we add only one peer then trx will fail during validation with Reason code [ENDORSEMENT_POLICY_FAILURE] because trx.proposal was sent only to one peer.
kiattchaip (Tue, 27 Mar 2018 09:32:19 GMT):
@IgorSim For now, the answer is yes. In 1.2.x version, however, Fabric will have an ability to discover peers and we don't need to do this anymore.

Hi @rickr . I am upgrading our applications to fabric 1.1.0 and I wanted to upgrade the java sdk to.

What you're probably waiting on is for all the events to be seen by peer event services and event hubs in their blocks. That's not atypical
albert.lacambra (Mon, 02 Apr 2018 13:40:38 GMT):
However I am not seeing any v1.1.0 and only the alpha version is there
albert.lacambra (Mon, 02 Apr 2018 13:41:08 GMT):
is the alpha version stable enough or should I better take from master?
albert.lacambra (Mon, 02 Apr 2018 13:41:42 GMT):
there are issues if keep with version 1.0.1 if we keep working with eventhubs and are not using the peereventing feature?
rickr (Mon, 02 Apr 2018 13:43:26 GMT):
Use 1.1.0-SNAPSHOT
rickr (Mon, 02 Apr 2018 13:43:26 GMT):
Use 1.1.0-SNAPSHOT which is master/latest
albert.lacambra (Mon, 02 Apr 2018 13:44:42 GMT):
ok. thx.
albert.lacambra (Mon, 02 Apr 2018 13:47:35 GMT):
from wich mvn repo should I take it?

I did a long while back using my own code to read the network config that is provided. But you need to work through IBM channels with any issues you have with bluemix

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=ZoCZZn7RwrLvMMbGG) @huy.tranibm
When the channel is initialized it gets the root CA certs from the latest config block. The signature from the endorser needs to be in one of CAs. I'm guessing it's not.

Too many variables unknown. Was the actual name the same ?
albert.lacambra (Mon, 02 Apr 2018 14:46:04 GMT):
Until now we have gone ahead of it using our own patch.
albert.lacambra (Mon, 02 Apr 2018 14:46:18 GMT):
Is not yet fixed or is not a bug and we are doing something really wrong
albert.lacambra (Mon, 02 Apr 2018 14:46:30 GMT):
the ChaincodeID builder does not allow null values, so, ....
rickr (Mon, 02 Apr 2018 14:46:52 GMT):
Yes --- Java chaincode is not supported.
rickr (Mon, 02 Apr 2018 14:47:22 GMT):
and when it is it would NOT have a chaincode path
albert.lacambra (Mon, 02 Apr 2018 14:53:38 GMT):
well, it is not that I set it. It autmoatically set an emptyString
albert.lacambra (Mon, 02 Apr 2018 14:53:42 GMT):
""
albert.lacambra (Mon, 02 Apr 2018 14:53:53 GMT):
so there is no way to get rid of that without the patch
albert.lacambra (Mon, 02 Apr 2018 15:00:33 GMT):
I have seen on github several time the patch to be merged. Even it is not "officially" supported, we will be thankful if you just add this small fix check
albert.lacambra (Mon, 02 Apr 2018 15:00:41 GMT):
specifically if (null != this.chaincodePath && !this.chaincodePath.isEmpty()) {
throw new IllegalArgumentException("chaincodePath must be null for Java chaincode");
}
albert.lacambra (Mon, 02 Apr 2018 15:00:41 GMT):
specifically if (null != this.chaincodePath ----->&& !this.chaincodePath.isEmpty()<----) {
throw new IllegalArgumentException("chaincodePath must be null for Java chaincode");
}
albert.lacambra (Mon, 02 Apr 2018 15:01:17 GMT):
that would solve the issue
albert.lacambra (Mon, 02 Apr 2018 15:01:22 GMT):
:D
albert.lacambra (Mon, 02 Apr 2018 15:31:58 GMT):
What do you think @rickr ? If you are interesting I can even send the patch...
rickr (Mon, 02 Apr 2018 15:40:48 GMT):
I don't think I want it fixed that way.

Is this only on a query ? If you send a proposal to execute CC it fails too ?

yes its a query, when i send an invoke, i get the txId but the verify() still is false

NO -- If this only is being reproduce in BMX it needs to be addressed by them

I don't think there's anything you can do on the client side that's going to make that work

rickr (Mon, 02 Apr 2018 17:37:49 GMT):
Here is what I've seen in the past. BMX team only test Node and GO. These implementations from what I've experienced are extremely tolerant of loosely defined certificates. Java is more strict. Note we only call JCE so there's really little here for the Java SDK to do different.
You may try IBM JDK too but also from what I've *experienced* it's even more strict than Oracle and Open JDK
huy.tranibm (Mon, 02 Apr 2018 17:39:13 GMT):
man o man
rickr (Mon, 02 Apr 2018 17:41:20 GMT):
The fact that they even excepted the proposal and verified it was ok, most likely means the we are signing and using the same crypto/curve strengh and hash. So there little chance those are wrong and trying to change any of that is not IMO going to get you anywhere

I can't even get my chaincode to instantiate from the console. There's some problem that the logs aren't helping with to do with either peers not connecting properly to the orderer or to the channel. I mocked up a channel connect and after getting past the openssl and tls debacle that let me connect.

edit: There was a comment about it getting the root CA certs. This isn't related to the CA having the wrong cert by any chance is it?

Ok, I've already checked that but in my research. I was checking how to get the channel config and info according a json config that I have
davidtoro92 (Mon, 02 Apr 2018 20:09:02 GMT):
'cause the params of that method are HFClient and Channel
davidtoro92 (Mon, 02 Apr 2018 20:10:12 GMT):
In addition y see `Channel barChannel = constructChannel(BAR_CHANNEL_NAME, client, sampleOrg);`
davidtoro92 (Mon, 02 Apr 2018 20:10:40 GMT):
the assert is generating a channel "on the fly". But I have a remote channel to listen

while adding new org to existing network, how to avoid init in upgrade call?
aatkddny (Tue, 03 Apr 2018 12:43:11 GMT):
is there a formal definition of the NetworkConfig anywhere? Curious as to whether there's a problem with the SDK or IBMs implementation. In particular (or more accurately my actual issue right now) is the "registrar" field in the SDK. The ` JsonObject registrar = getJsonValueAsObject(jsonCA.get("registrar")); ` implies a single value, but IBM is returning an array. Trying to figure out which is correct, or if it's a free for all.

It looks to be dying here: ` this.filterBlock = peerOptions.isRegisterEventsForFilteredBlocks(); `
Called from here: ` PeerEventServiceClient lpeerEventingClient = new PeerEventServiceClient(this, new Endpoint(url, properties).getChannelBuilder(), properties, null); ` That's clearly wrong. The call is passing a null to the constructor.

aatkddny (Wed, 04 Apr 2018 14:27:55 GMT):
right. and its passing a null. that's not what was expected i'm sure. FAB-9333 covers it
rickr (Wed, 04 Apr 2018 18:12:06 GMT):
@kelvinzhong I'm not certain what feature you are referencing but if it's related to FAB-8718 The only support that the SDK needs for it is sending transient data with the proposals. The JSDK has had that for quite some time. You should find examples of how it's used in the End2endXX integration tests.
rickr (Wed, 04 Apr 2018 18:21:32 GMT):
@pankajcheema Many have asked for it but no one will step up to do it.
As for me I would never use it and probably not recommend it.
Look at Fabric docs to get the concepts. Each SDK should not have to provide that. Get the End2endITxx.java integration to pass. Get a debugger and spend a day walking through the code. It's like your own personal demo you can step through and observe all the variables and see whats going on. Even the asserts for testing can at times be helpful or just ignored.
You know the code and what you're looking at is up todate because it' passing :) You also then have a base of code you steal from for your own application Tutorials IMO don't get updated as the should.
I'm not opposed for someone doing a tutorial if they're so inclined and want to offer it.

If you're wanting to be on v1.1.0 of the SDK please either get the latest code or if you're already embedding in an application use the SNAPSHOT-1.1.0 for the version in your pom.xml dependencies. This will help the SDK to find bugs that are current that we have missed. If you do have issues the first thing we'll as is to move to that level.

If you are open to a suggestion - one of the things that might cut down on "how do I" questions would be to add a few more comments to the code. In particular where things changed between versions. A few lines there may save a lot here.
I'll give you a slightly contrived for instance - I see that a channel can be serialized and deserialized. Great. I'm sure it does something valuable, but I still have no idea why I'd do that over just reconstructing it. Two lines in the comment to say why would stop me having to ask.

aatkddny (Wed, 04 Apr 2018 19:32:34 GMT):
Yes. Absolutely they do. But I was looking at your suggestion to "get a debugger and step through the code". There's no substitute for knowing *why* something is going on as you see it happen as a learning tool.
rickr (Wed, 04 Apr 2018 19:37:26 GMT):
Well being close to something makes it a little more difficult at times because it's clear in your mind. I more than welcome comments to clarify or even provide gerrit patches to any of the code to just clarify something.

i have some eventing requirements that require updates on a channel to be propagated to another channel. the original user doesn't have access to the second channel.
it all works fine. my question is one of style.
is there any reason i shouldn't connect to all my channels and register my event handlers when i stand up my application, rather than piecemeal as required?
huy.tranibm (Thu, 05 Apr 2018 00:59:54 GMT):
updates as in channel configuration updates?
aatkddny (Thu, 05 Apr 2018 01:10:16 GMT):
no - adding or updating an asset.
aatkddny (Thu, 05 Apr 2018 01:10:45 GMT):

Has anyone try to run the java sdk multithreaded?
My question - to be a little more precise - is that a tight coupling between the HFClient and the Channel objects exists.
aatkddny (Thu, 05 Apr 2018 12:23:54 GMT):
Has anyone try to run the java sdk multithreaded?
My question - to be a little more precise - is that a tight coupling between the HFClient and the Channel objects exists.
The HFClient requires a user to be set in the UserContext. In a high performance environment with multiple users, must I wait until a dispatched transaction completes (which implies I'd need either a channel per thread or a synchronization or queuing mechanism) or is the whole thing already thread safe?
aatkddny (Thu, 05 Apr 2018 12:37:45 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=K3urWXXz5LEmzZRyq)
So does this imply that in a multithreaded environment that if I dispatch transactions against a predefined channel, I must wait for completion before dispatching on a new thread with a different User set in the HFClient for that Channel? Or to put it another way I either need multiple channel instances - perhaps per thread, synchronization on the client, some kind of queueing mechanism to be thread-safe?

rickr (Thu, 05 Apr 2018 13:03:20 GMT):
Not sure how you come to that conclusion. All methods for proposals endorsement allow you to specify a client context.
rickr (Thu, 05 Apr 2018 13:03:20 GMT):
Not sure how you come to that conclusion. All methods for proposals endorsement allow you to specify a user context.
Those are synchronous so they'll complete on the same thread they were issued. Many threads _should_ be able to submit proposals for endorsement independently. The sendTransaction to the orderer also has several options to give a user context and _should_ allow for many threads to submit transactions to orderer independently. For sendTransaction the Future it returns _should_ be able to be also processed (waited on) by yet another independent thread than what submitted it to the orderer.
The reason for the _should_ is that I attempted to make all of those thread safe. I had some bandwidth a long time ago to do some testing but that's been _along time ago_. I'll be the first to admit that muti-threading testing has not be done
heavily so it would be no surprise if there are *issues* yet to be found.
Just to make sure it's clear that if you create proposals on independent threads that modify on a channel/chain the same key data you'll will get alot of invalid transactions.
aatkddny (Thu, 05 Apr 2018 13:27:48 GMT):
Vis-a-vis the latter - I know. :D
It's not my code and I'm not throwing stones, but it seems that the singleton HFClient in the channel makes it implicitly unsafe. I can't see how I can safely modify the user context in a second thread while a `channel.sendTransactionProposal` is in flight. It's probably fine until I get to a multi-user multi-thread scenario. In that case do you have a recommendation between create a channel pool or synchronize?

aatkddny (Thu, 05 Apr 2018 13:42:00 GMT):
I know I can set it, but is it not set for the duration of the transaction - meaning I can't safely modify it in flight with a second Tx in a different thread that sets it. I didn't see a clone of the HFClient or even the User.

Each thread should have it's own transactionRequests
aatkddny (Thu, 05 Apr 2018 13:48:00 GMT):
NM - I see you are pulling the context in getTransactionContext. My exposure then should only between setting the UserContext in the HFClient and doing the `client.newTransactionProposalRequest()` and I can refactor to minimize that.

rickr (Thu, 05 Apr 2018 13:52:06 GMT):
Do a `client.newTransactionProposalRequest()` If you have no threading issue in your application your good.
If you do and they're switch the user context either your application needs to coordinate that (rather ugly) Or just ignore what it defaults to in your thread and always set TransactionRequest.setUserContext to the user context that your thread expects the context to be
aatkddny (Thu, 05 Apr 2018 13:53:14 GMT):
I'll adopt the brute force approach and do the latter. Thx.

Perfect. Thanks. That jibes with what I thought my issue was - the event's firing twice, once for each org with a listener - it doesn't filter by org. So I need to track it outside of the HFClient -> channel methodology that everything else uses.

Actually it's firing three times - each time for the same user/client/channel/peer in the same org for the same handler for the same transaction id. Now I'm totally stumped.

Which means events in this case need to be idempotent.
kkado (Sat, 07 Apr 2018 04:17:13 GMT):
Has joined the channel.
rickr (Sat, 07 Apr 2018 15:07:14 GMT):
yes
rickr (Sat, 07 Apr 2018 15:07:14 GMT):
yes - in a blocklistener you'll see an event (block) for each peer eventing service and each eventhub. The event has the source that received the event.
aatkddny (Sat, 07 Apr 2018 15:38:47 GMT):
So simply as a point of style.
Idempotent transactions in this case are failing with a "status 11" - which means an MVCC exception.
Which makes sense - the same transaction firing one event in the CC is triggered multiple times at the listener. This in turn dispatches the same Tx twice concurrently. One works, one fails with an MVCC exception.
I really need to only dispatch once. Or to serialize so that a Tx event can only be in flight once (if event is idempotent).
So I can either try to turn off either the event or the peer notifications. I'm guessing poking in one of those peer properties into my NetworkConfig might help there.
My second option is to keep track of the Tx Id and if I already dispatched elsewhere don't dispatch here. I'm not worried about the additional complexity but I'm not a fan of the additional external reference, even if I keep it cached and time it out rather than persistent somewhere.
My third would be similar to 2 but to latch - suspend the second dispatch until the first has completed.
My final option would be to figure out the source of the event and only dispatch from (say) a peer.
aatkddny (Sat, 07 Apr 2018 15:38:47 GMT):

A few minutes of quality time with the debugger shows the eventhub and peer are mutually exclusive (one is null if the other is set) in the BlockEvent object. Which I assume is the source you are referring to above. If that's the case, and I choose the final option, am I correct in the assumption that I"m better to trigger from the Peer - I understood that the EventHub was being deprecated. Or did I misunderstand?

If that's the case, and I choose the final option, am I correct in the assumption that I would be better served to trigger from the event that sets the Peer - I understood that the EventHub was being deprecated. Or did I misread that?
aatkddny (Sat, 07 Apr 2018 15:38:47 GMT):
So simply as a best practices question...
Idempotent transactions in this case are failing with a "status 11" - which means an MVCC exception.
Which makes sense - the same transaction firing one event in the CC is triggered multiple times at the listener. This in turn dispatches the same Tx twice concurrently. One works, one fails with an MVCC exception.
I really need to only dispatch once. Or to serialize so that a Tx event can only be in flight once (if event is idempotent).
So I can either try to turn off either the event or the peer notifications. I'm guessing poking in one of those peer properties into my NetworkConfig might help there.
My second option is to keep track of the Tx Id and if I already dispatched elsewhere don't dispatch here. I'm not worried about the additional complexity but I'm not a fan of the additional external reference, even if I keep it cached and time it out rather than persistent somewhere.
My third would be similar to 2 but to latch - suspend the second dispatch until the first has completed.
My final option would be to figure out the source of the event and only dispatch from (say) a peer.
A few minutes of quality time with the debugger shows the eventhub and peer are mutually exclusive (one is null if the other is set) in the BlockEvent object. Which I assume is the source you are referring to above. If that's the case, and I choose the final option, am I correct in the assumption that I would be better served to trigger from the event that sets the Peer - I understood that the EventHub was being deprecated. Or did I misread that?
And as a followup - since setting it up to test will be a chore. Does anyone know if an event is dispatched for *every* peer. So if I had 4 peers I'd either get 5 or 8 events? This network has one peer per org and I'm hesitant to extrapolate.
rickr (Sat, 07 Apr 2018 16:07:42 GMT):
You'll see an event for each Peer that is an event source and each event hub. My understanding is eventhubs will eventually be removed.
No shoe fit's all sizes - In general an approach I would take in a block listener is that the block numbers are increasing. Keep track of the latest block number, throw out what you've already processed. Should mean you process that block just once and you'd get redundancy if one Peer eventing service or eventhub is not reporting the block listener would continue processing the events.
I would move away from using eventhubs to just using peer eventing services
rickr (Sat, 07 Apr 2018 16:22:14 GMT):
Should note in the approach above that because a block has been committed on one peer and your blocklistener thus gets that event does not mean that any other peer has yet committed it :wink:

I have a Java SDK based client for the Hyperledger fabric and am able to connect and send transaction proposal requests, create entries in the ledger and query the ledger.
I am struggling with registering and listening to BLOCK and CHAINCODE events. I want to start a separate thread on the client that is dedicated to listening and processing these events.
What I found so far:
HFClient client = HFClient.createNewInstance();
Channel channel = client.newChannel("channel01");
EventHub eventHub = client.newEventHub("eh01", "grpc://abc.xyz.us:7053");
channel.addEventHub(eventHub);
Beyond this I am lost. Can someone please post a sample of how to do this?
rickr (Sat, 07 Apr 2018 16:33:06 GMT):

aatkddny (Sat, 07 Apr 2018 16:55:47 GMT):
There's also - as an fyi for anyone else in this situation - a retry mechanism. It singly retries if the fired event hasn't been committed after 10 minutes - meaning you don't get a second one after 20 minutes. Retry is coming from the peer. I'm waiting to see if responding to the event hub but suspending in the peer still triggers it.

Edit - it still does. So as an additional wrinkle the peer eventing has a time-based retry. Complete your events in 10 minutes or it'll refire.

Hello guys, I am just testing out the java sdk version 1.1.0-alpha. As network environment I use the provided docker images used in the integration tests however i write my own application code. I managed to create the 'foo' channel. However I cannot find it anymore with the client.getChannel("foo") method. Any ideas?
HofmT (Sun, 08 Apr 2018 16:56:15 GMT):
I found the solution. Instead of using method getChannel you have to use method newChannel(String name). This is very confusing. :D Can anybody explain me why there even is the getChannel() method?

@rickr Yes, I'm reading through the End to End Test Scenario code. But they perform all the operation with the channel once it is created. In my code I just create the channel and then when i rerun the code I want to use the previously created channel however there is no real method to get the already configured channel.

@donsonZhang The user context is used as a creator of a transaction and it is nothing to do with the endorsement policy. The transaction need to be sent to and signed by the number of peers (endorsers) depending on the endorsement policy to make it valid. However, I don't know how to assign role (member or admin) to the peer. I have asked this question at stackoverflow but it has not been answered.

@donsonZhang There is an example that shows endorsement policies being used .. see
run demo once it should work. both peers have endorsed.
do:

Now only one peer is endorsing and it fails ...
Now do:

rerun and it should work because only one endorsement is then needed.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=mp52QxkEeCtTzF3ns) @rickr I didn't had the time to check the logs peer. I had to demo my work quickly. However, I workarounded the issue. Indeed, it should be a network issue between the SDK and the peer when listening the events over the eventhub. My Java application is deployed on the same machine as the 4 peers ran by the byfn.sh. I configured the SDK (channel.addPeer) to reach the peers and the eventhub using the public DNS Name. Thus the SDK resolve the public DNS entries, to public IP addresses, go out from my Azure machine to Internet and get back to the same machine on the peers ports. As the communication is using 'grcps' protocol which seems to be a streaming protocol (I am not an expert here), the socket should be maintained. I think this is prohibited by Azure (at least in the default config).
To workaround this, I put my Java application running the SDK on a docker container running on the same network as byfn.sh. Thus, my SDK resolves the peers addresses locally (to docker network), and communicate with the locally. The grcps protocol is not interrupted anymore by Azure equipment (or policy) and the problem is gone. I had also to disable my local firewall (ufw & iptables) on my Ubunut 16.04.

Hi all, I'm creating an instatantiateProposalRequest just like in the EndtoEnd example with setFcn('init') and setArgs(new String[] {"a","100"}). However when sending the proposal to the blockchain it always keeps adding the function name to the arguments array. Inside my chaincode code I use the function: getFunctionAndParameters() in order to seperate between function name and arguments but it keeps the function name inside the arguments array. What do I forget?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=KRTDKJ4ZeFCS9KvMH) @rickr thank you for the answer, it was a maven assembly issue, switching to shade solved it.
aatkddny (Thu, 12 Apr 2018 18:14:54 GMT):
I looked in the samples and didn't find it. It's entirely possible I overlooked it. This is a clarifying question...
It appears that when you are installing a newer version of the chaincode - say 1.1 on top of 1.0 - that at the point where you would instantiate it if it were the first time, you need to check that the name matches - and only the name (ignoring version and path) - and if (and only if) there's a match, switch from `newInstantiationProposalRequest` to `newUpgradeProposalRequest`.
The reason I'm asking the clarifying question is because the checks in End2endAndBackAgainIT all seem to check the version (and optionally path). The error from fabric if you try to instantiate the 1.1 implies it only cares about the name though.
Is that expected behavior?
rickr (Thu, 12 Apr 2018 20:37:55 GMT):
yes

hi guys, just a quick question: we would like to use Java or Node SDK for our project. The main part of the system is written in Java so the easiest solution would be to use the java sdk, however it seems it is not as developed a the Node one. What do you guys think?
aatkddny (Mon, 16 Apr 2018 12:44:08 GMT):
well it doesn't have a ui and the manual is mostly follow the code, but it's certainly functional. So are you asking if it's as slick as the node version - no. does it do everything you need to interact with a fabric - yes. or at least it does everything we need it to in the application we have running. does that help?
aatkddny (Mon, 16 Apr 2018 12:44:08 GMT):

szlaci1983 (Mon, 16 Apr 2018 12:57:35 GMT):
thanks @aatkddny . Yepp I am mostly interested about functionality. and if it is deveoped in parallel with the Node version, or is it behind in terms of functionality?
aatkddny (Mon, 16 Apr 2018 13:01:17 GMT):
you'd have to ask the guys that develop it. it seems to keep pace with HL releases afaict - but I've only used it for 1.0 and 1.1.
szlaci1983 (Mon, 16 Apr 2018 13:03:19 GMT):
ok thanks @aatkddny
rickr (Mon, 16 Apr 2018 13:21:03 GMT):
From a functionality of working with Fabric there is nothing I know of that the JSDK doesn't do that Node SDK does. Outside of that the JSDK does not provide persistence that is left to the application. Given that there are so many persistent technologies to do it right (technology persistent agnostic, not enforce any schema) would mean defining numerous callback and an whole architecture/api to do so. It's just as easy for any application to do so on it's own. Having said that the Java SDK can Java serialize/deserialize channels -- I'm not certain but I don't think there's any such mechanism in the Node SDK. The JSDK when going to the orderer gives you a future/promise with now options that resolve the promise when the transaction is observed to be completed - AFAIK the node sdk leaves it to you create your own block listener. The JSDK when going to orderer or for many queries will try all orderers or peers to try to complete the request -- Last I seen the Node SDK doesn't do that. For peer eventing service the JSDK allows the definition of handler to restart the service and default will retry where it left off -- the Node SDK last I seen wont' do that it just gets the next block. There may be things the JSDK does not do that Node does that I'm not really aware of and I don't want to get in some heated debate on it. If you know that there some lacking functionality please open a JIRA for it.

I will say.. from a testing perspective the Node SDK has more thoroughly flushed out -- because it's used by hypleger composer and I know there is a lot of resources to make sure that is working --- even to the fact that it was more important to have Node CC supported while Java CC is still just experimental!

the bar to entry is higher.
szlaci1983 (Mon, 16 Apr 2018 15:15:09 GMT):
thanks @rickr next is: hands up who is using JSDK :D
rickr (Mon, 16 Apr 2018 15:23:44 GMT):
`The bar to entry is higher.` How so? I think it depends heavily on your skill and maybe how you can learn. I know of people who have followed the README.md , They know Java/ an IDE / maven and the basics of Fabric. Is that too high of a bar to ask for? They got their environment up and running in minutes and validate the the integration test were working. Then took the time in a IDE debugger to look at those examples/ I've heard about four hours to walk through the integration examples. After that they were pretty much ready to take the code from those and get their apps working.
aatkddny (Mon, 16 Apr 2018 15:31:53 GMT):
` I think it depends heavily on your skill and maybe how you can learn ` <- doesn't that pretty much define the bar to entry?
aatkddny (Mon, 16 Apr 2018 15:31:53 GMT):
` I think it depends heavily on your skill and maybe how you can learn ` <- doesn't that pretty much define the bar to entry? You can do something in composer almost instantly, knowing nothing. Here there's a certain bar you need to meet before you can do the same.

` I think it depends heavily on your skill and maybe how you can learn ` <- doesn't that pretty much define the bar to entry? You can do something in composer almost instantly, knowing nothing. They gave you a UI and a ton of pretty manuals to hand hold you through the process. Here there's a certain bar you need to meet before you can do the same.

You'll note I didn't say it was too high, just higher...
rickr (Mon, 16 Apr 2018 15:40:52 GMT):
I don't think that's a fair comparison at all. Compare both SDKs. Not some UI code generator on top of one and an SDK. Also provide a whole team for a Java Composer equivalent and then compare those.
rickr (Mon, 16 Apr 2018 15:55:33 GMT):
BTW not to knock composer at all. It's probable a GREAT interface and yes gives you a much better _initial experience_ working with Fabric. However, it's my own *general* experience that all of these code/generates work great at first but when the _rubber hits the road_ and you get more requirements for what you're doing you find what it creates won't easily meet that your left with a bunch of code that you know little of and can't really maintain or improve upon what the `framework` allows you.

i learned through the NODE sdk examples
huy.tranibm (Mon, 16 Apr 2018 15:57:08 GMT):
took those steps and applied it to Java sdk
huy.tranibm (Mon, 16 Apr 2018 15:59:06 GMT):
but rick is right, best way to learn without a manual is debug, but even with a manual, how many would really read through it?
rickr (Mon, 16 Apr 2018 16:05:29 GMT):
Exactly. How many come here asking questions that are blatantly obvious they haven't spent the ten minutes tops to read through the README.md. So what's the hope they'll what to spend that on reading a manual that may take a day or possible two? :scream:

@lmars, thanks. I've disabled TLS on peer0 and SDK is now able to connect. Any idea why would TLS prevent connectivity between host and the guest OSs?
rickr (Mon, 16 Apr 2018 16:57:47 GMT):
So TLS was enabled on both sides and then you disabled them both and it worked ?
rickr (Mon, 16 Apr 2018 17:02:32 GMT):
Also I've never seen logs or output like ``localhost/0:0:0:0:0:0:0:1:7051`` what generally is displayed in just the logs is ```loc

@asharora78 Doesn't look like the sdk is current from that stacktrace .. How about sharing what version of the SDK and Fabric you're using might be helpful. What was on the Orderer did you look at that ?
asharora78 (Mon, 16 Apr 2018 17:50:48 GMT):
@rickr java sdk version is 1.0.1, fabric version is 1.0 and I specifically put up orderer logs in follow mode and didn't see any request coming there.....:(
rickr (Mon, 16 Apr 2018 17:58:03 GMT):
Probably should put at least the Orderer in debug mode the JSDK has that set on it's docker-compose by default. In the readme.md too. You can also put the SDK into trace mode it's documented too. Maybe helpful
rickr (Mon, 16 Apr 2018 18:00:03 GMT):
Another option is to use the latest SDK it should be backward compatible
asharora78 (Mon, 16 Apr 2018 18:07:19 GMT):
@rickr - Orderer is in debug mode, I have following property set in compose file ORDERER_GENERAL_LOGLEVEL=debug, however I didn't see any log coming up when I ran java program, let me try putting SDK in trace mode if that doesn't work ... then would upgrade SDK version if it still doesn't work, would come back to you....however I thought this error " ERROR OrdererClient - Channel mychannel sendDeliver time exceeded for orderer orderer.gsa.com, timed out at 10000" might be saying something obvious which I am not able to see :(

rickr (Mon, 16 Apr 2018 18:10:34 GMT):
try to up that .. though 10 sec seems excessive.
asharora78 (Mon, 16 Apr 2018 18:11:19 GMT):
It was initially set to 3 sec, I thought it was less so I added property with 10 seconds
rickr (Mon, 16 Apr 2018 18:13:50 GMT):
Try to up it to a minute ... just for the _fun of it_

lmars (Mon, 16 Apr 2018 18:25:25 GMT):
@maxd001, you should configure TLS on client side before use. Please, see for example:
https://github.com/hyperledger/fabric-sdk-java/blob/11bd160a95fa8529d93582ec68556bb1c4652c21/src/test/java/org/hyperledger/fabric/sdk/testutils/TestConfig.java#L289
aatkddny (Tue, 17 Apr 2018 00:26:54 GMT):
Anyone have an example of configuring the HFCAClient to use TLS on the CA?
I thought it was as simple as setting up the Properties like this (so the same as for a channel). Ignore the getters - this is from a persisted definition.
``` Properties p = new Properties();
if (ca.getProtocol().equals(Protocol.HTTPS)) {
p.put("sslProvider", ca.getSslProvider());
p.put("hostnameOverride", ca.getName());
p.put("negotiationType", ca.getNegotiationType());
p.put("pemBytes", Encryption.base64Decode(ca.getPemBytes()));
}
```
But it doesn't seem to work. The PEM here is the CA cert in the org directory (ca-{org}-cert.com. It's set in the CA compose. Name is the domain name - which is the same as for a peer.
My error is: o.hyperledger.fabric_ca.sdk.HFCAClient : Certificate for doesn't match any of the subject alternative names: []
I'm sure it's something stupid, but figuring our what the stupid thing I did is will be easier with a working example to compare against.

HFCAClient has its own setupSSL() method
aatkddny (Tue, 17 Apr 2018 00:39:43 GMT):
i get that. but i'm not seeing why not. i figured localhost in the alternate names would suffice here for this test. sslprovider is the usual "openSSL".

if i was to test locally then i'd add hostnameOverride but nothing else
aatkddny (Tue, 17 Apr 2018 00:42:08 GMT):
so you are only adding the pem. not the provider or negotiation type. let me try that.
huy.tranibm (Tue, 17 Apr 2018 00:42:15 GMT):

leave your hostnameOverride, i believe that's required for local
aatkddny (Tue, 17 Apr 2018 00:44:26 GMT):
didn't make a bit of difference. tried "localhost" in my hostnameoverride. also tried the actual domain in there. neither worked.

your using docker right?
huy.tranibm (Tue, 17 Apr 2018 00:50:02 GMT):
do docker ps

huy.tranibm (Tue, 17 Apr 2018 00:50:30 GMT):
its tricky

yes

I am working with the Java SDK (v.1.1.0-alpha) to bring up a fabric network and got a question regarding Channel Initialization. In the java code from the channel initialize function, we call the parseConfigBlock func, which in turn calls the getConfigBlock, which uses a randomly selected peer (which is given by the getRandomPeer func). And eventually, we call the sendProposalToPeers function as part of channel initialization.
When there are multiple MSPs involved, how do we ensure that the peer returned by the getRandomPeer function has the same MSP as the userContext used in the HFClient when calling the sendProposalToPeers?
Is there a relevance to using a randomly selected peer? In other words, if I can tell the channel initialize function to use a specific peer, is there anything incorrect in doing so?
More detail:
My Scenario:
In my code, I am doing this (for simplicity, assuming multiple org, with each org having its own MSP and each org having one peer) :
`
for (FabricOrg org : myOrganizationCollection) {
setup-hfclient-with-org-msp-usercontext
Peer peer = define-org-peer-using-hfClient.newPeer(...)
mychannel.joinPeer(peer)
}
if (myChannel is not initialized) {
myChannel.initialize()
}
`
As you can see, when I call myChannel.initialize(), the hfClient's user context would be the user context of the last organization from the myOrganizationCollection; however, since initialize func uses a randomPeer, the MSP from hfClient UserContext may not match the random Peer's MSP.
As a test, I ended up modifying the sdk code to use a specific peer supplied by me, which works, but Is there a correct way to do this?

@aatkddny Appears to be working when integration tests are enabled for TLS. If your url hostname of server does not match the CN of the cert from the server you'll need to add that `allowAllHostNames`. Something that shouldn't be an issue in production where that should never be the case.

I wish to make a possible controversial change to Gerrit. I'm asking all the teams that use Gerrit. May I require JIRA links in all Gerrit changes? this isn't something I can enable on a per-project basis.
rickr (Tue, 17 Apr 2018 23:43:40 GMT):
Well my feedback
I'm surprised that maintainers can not be trusted to not merge a gerrit CR without there being a JIRA for it ? I'm mean if they can't do that can they really be trusted to give a reasonable code review ?
Since I've been working on the JAVA sdk I have nor has anyone else merged a change that didn't have a JIRA item associated with it. So to me this looks like a solution looking for a problem to fix.
Given that :
I don't think the should be required for draft changes put to gerrit those should be exempt. They can't be merged till published anyway.
Unlikely, but what if JIRA is out and we need to push something through ASAP (once again it seems maintainer should be able to use their discretion )
I prefer link that just have FAB-xxx then the [FAB-xxx] there's too little allowed characters on that line which is actually for a bigger issue that this.
If really really needed I think the check should be on the merge just like the build verify with maintaineers being able push come to shove override.

another project puts the JIRA in the block at the bottom, which I also think is nicer, but I also think that's a style thing.

this is what I am doing:
TransactionInfo txInfo = this.channel.queryTransactionByID(transactionId);
Payload p = Payload.parseFrom(txInfo.getEnvelope().getPayload());
String str = new String(p.getData().toByteArray());
BufferedReader bufReader = new BufferedReader(new StringReader(str));
But unfortunately, I didn't find any stuff in the SDK to parse the transaction data. I was hoping something like payload.getData(), and the returned datas should be structured as they are saved by chaincode...
We can collaborate in the SDK of course :-) to implement that if we have the structure's doc...

When I use someone else's Fabric it's all "loadFromNetworkConfig" - or more accurately the one I've used is.
Is the intent to switch over to this form so that I'll need to change my definitions to fit into that structure or will both types of initialization be supported in parallel?

huy.tranibm (Mon, 23 Apr 2018 12:50:36 GMT):
@aatkddny you may want to use both ways. Consider when you want to join a peer to another channel. When using loadFromNetworkConfig, the peers/orderers instances are already assigned to the channel object it came from. So when you get your peers/orderers from loadFromNetworkConfig and try to join them to another channel, you'll get an "**** is already in channel ****" error.

I had common code for simple things like joining a client to a channel, but if the networkconfig stuff is going to be ubiquitous i may rewrite the common to support that and have my management functions seperate.

@nikolas don't use the zip definitely use the clone. I've not heard anyone else report an issue like that
nikolas (Mon, 23 Apr 2018 13:54:38 GMT):
hi @rickr thanks for the answer. No clue what the issue with eclipse is :( it is a fresh install on a windows 10 machine
rickr (Mon, 23 Apr 2018 13:58:09 GMT):
I don't use eclipse nor windows I seen there was checked in a .project .class files which I think shouldn't be there try to delete them Look at README.md it include some eclipse instructions
rickr (Mon, 23 Apr 2018 13:58:55 GMT):
You should import the project as a maven project
rickr (Mon, 23 Apr 2018 13:59:29 GMT):
before you do that I would see the integration tests are completing
nikolas (Mon, 23 Apr 2018 14:02:25 GMT):
i will try and will report back
nikolas (Mon, 23 Apr 2018 14:02:28 GMT):
tnx
nikolas (Mon, 23 Apr 2018 14:09:41 GMT):
@rickr after removing the .project file, at least imports successfully as maven project. so this should be out of the repo
nikolas (Mon, 23 Apr 2018 14:15:15 GMT):
are there any examples of the java sdk, using user keys & certs generated by the cryptogen tools instead of enrolling via ca?
huy.tranibm (Mon, 23 Apr 2018 16:15:20 GMT):
@nikolas its mostly all using cryptos generated from cryptogen except for when registering/enrolling user1
donsonZhang (Tue, 24 Apr 2018 03:20:33 GMT):
@huy.tranibm the`channel.updateChannelConfiguration(updateChannelConfiguration, new byte[][]{client.getUpdateChannelConfigurationSignature(updateChannelConfiguration, ordererAdmin)});`
donsonZhang (Tue, 24 Apr 2018 03:20:55 GMT):
is the result of build, it is the same to
donsonZhang (Tue, 24 Apr 2018 03:21:14 GMT):
` channel.updateChannelConfiguration(updateChannelConfiguration, client.getUpdateChannelConfigurationSignature(updateChannelConfiguration, ordererAdmin));`
donsonZhang (Tue, 24 Apr 2018 03:21:53 GMT):
and my code is
donsonZhang (Tue, 24 Apr 2018 03:22:02 GMT):
`channel.updateChannelConfiguration(updateChannelConfiguration, client.getUpdateChannelConfigurationSignature(updateChannelConfiguration, ordererAdmin));`
donsonZhang (Tue, 24 Apr 2018 03:23:41 GMT):
so my question:
donsonZhang (Tue, 24 Apr 2018 03:24:08 GMT):
`set the anchor peer
`UpdateChannelConfiguration updateChannelConfiguration = new UpdateChannelConfiguration(new File("Org1MSPAnchors.tx"));
client.setUserContext(ordererAdmin);
channel.updateChannelConfiguration(updateChannelConfiguration, new byte[][]{client.getUpdateChannelConfigurationSignature(updateChannelConfiguration, ordererAdmin)});`
java client get the err:

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=wyLi9HjPtpGh8tn46) @rickr About this, dont need an exact date or something, but even an approximate idea would do, thanks! :)
amolpednekar (Tue, 24 Apr 2018 07:08:56 GMT):
Another question, in the readme, its mentioned under "Known limitations and restrictions", that "HSM not supported. JIRA FAB-3137"
But according to https://jira.hyperledger.org/browse/FAB-3137, it's marked as resolved?
rickr (Tue, 24 Apr 2018 11:28:41 GMT):
I've not personally tested HSM. I do know of a group that provided some fixes and claimed they had HSM working. Most of the function's we now use are JCE/JCA. The SDK doesn't do any key management so there should be no issues with that.
amolpednekar (Tue, 24 Apr 2018 12:03:17 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=aKyeccMaj4xJZcjhz) @rickr Thanks, are you referring to the LunaHSM group? Did they create any readme for that?
Also, I'm guessing there's no concrete idea about the 1.1.0-release date
rickr (Tue, 24 Apr 2018 12:35:31 GMT):
Yup think it was Luna
asharora78 (Tue, 24 Apr 2018 12:54:46 GMT):
If I am using a two org (peer) setup and have the endorsement policy such that both peers need to endorse the transaction, then do I need to do anything extra from my client other than just sending the request to one peer, what I mean is, do I need to send transaction to both the peers and once I get back the proposal response than I need to assemble the endorsement and send the request to transaction service?
rickr (Tue, 24 Apr 2018 13:01:53 GMT):
Mostly handled for you other than tell which peers to send to and then verify that they have been endorsed and verified .. see end2end integration tests.
rickr (Tue, 24 Apr 2018 13:05:30 GMT):
You do need to specify which endorsement you want to send to the Orderer

asharora78 (Tue, 24 Apr 2018 13:19:03 GMT):
Ok, so as a client I don't have to worry about endorsement sending to Orderer, however if any transaction needs to be endorsed by multiple peers then I do need to send request proposal to each and every peer. The reason I am asking this is, I would assume that in a multi party setup every org app client would be sending request to their org peer without worrying about the other peers,
asharora78 (Tue, 24 Apr 2018 13:19:03 GMT):
Ok, that means if a new peer has been added into the channel it follows the AND endorsement policy then app client needs to be updated as well.
rickr (Tue, 24 Apr 2018 13:20:30 GMT):
y

aatkddny (Tue, 24 Apr 2018 13:31:47 GMT):
yes
aatkddny (Tue, 24 Apr 2018 13:31:59 GMT):
you need to add all the peers
aatkddny (Tue, 24 Apr 2018 13:32:15 GMT):
which is both a pain and seems counterintuitive.
aatkddny (Tue, 24 Apr 2018 13:32:34 GMT):
since you need the addresses of them but there's no network discovery
asharora78 (Tue, 24 Apr 2018 13:34:07 GMT):
Ok, that means if a new peer has been added into the channel it follows the AND endorsement policy then app client needs to be updated as well.
aatkddny (Tue, 24 Apr 2018 13:35:22 GMT):
you mean the HFClient? You may need to reinitialize the channel from the top. I haven't tried just adding a peer to one that's already there. If you do I'd like to know if it works.
asharora78 (Tue, 24 Apr 2018 13:38:26 GMT):
There has been a sample with 1.1 release that lets you add a new org in a running network, so what I wanted to know was if a new peer has been added into the network by virtue of new org being added to the network and there are already app client being used to connect with network then do we need to upgrade the client as well if the newly added peer is a must to endorse the transaction

aatkddny (Tue, 24 Apr 2018 13:40:59 GMT):
You will need to add it if it's an AND for the endorsement. Which was my point. I don't know if *just* adding it works. You may need to start over and re-initialize the channel from scratch.
asharora78 (Tue, 24 Apr 2018 13:44:25 GMT):
Ok, got it, would try and see if that works. And for multi peer endorsement rickr suggested that I shudl have a look at end2end integration test.

It's pretty simple if you use a document oriented database. We picked MongoDB - mostly because we are using it elsewhere so it was a good fit. One tip - if you run your crypto first and save the PEMs in your orgs, the rest of the code

Actually for full disclosure we went the other way - we build the whole network from the org records - including running the cryptogens and the configtxgens and building a docker compose file for each org that participates. It's actually quite doable if you template it all out, and one touch instantiation with the ability to add an org by changing some config is a real time saver for development.

Hi All - getting an error whilst creating container dev-peer1.org1.example.com-example_cc_go-1. The error message from peer1.org1.example.com docker log is:
Failed to generate platform-specific docker build: Error returned from build: 1 "can't load package github.com/example_cc: no buildable Go source files in /chaincode/input/src/github.com/example_cc".
I am not able to figure out where the path /chaincode/input/src/github.com/example_cc is referenced or where the chaincode should be deployed, i.e. does it need to be deployed on the docker instance for peer1.org1.example.com or the orderer or the java SDK side etc. Any thoughts?

Thanks @rickr, On the client side, where SDK is running, I can see

So from this I assume that SDK is able to locate the source files successfully.
But the issue I am facing seems to originate from the peer where it is trying to create an image with hyperledger/fabric-ccenv:x86-1.0.5 but it is not able to find the source files and hence crashes

maxd001 (Thu, 26 Apr 2018 13:59:12 GMT):
no it is the CC code that came with the SDK. what is different with my setup is that I have SDK jar imported into my project and CC structure created on one host and the fabric network setup on another host. I am also re-using TestConfig classes that came supplied with the SDK, but I have had to change the folder paths to suite my project structure.

@amolpednekar You can update an identity, including changing its password, by creating an HFCAIdentity object by passing the ID of the identity you want to update in it's constructor and then you can set the new password you want on this object and call the create method and it should update the identity's password.

so i'm trying to do a roll your own connection profile - similar to the bluemix one, so I can use the code interchangeably no matter where its hosted. i'm all good apart from eventing.
bluemix is throwing both the peer event and the eventhub one. mine isn't. anyone know what controls those two triggering before I go digging in the code?
aatkddny (Fri, 04 May 2018 01:29:01 GMT):
nm - found it
rickr (Fri, 04 May 2018 01:32:44 GMT):
The Java network config code will produce an eventhub if the peer has an `eventUrl` and an peer eventing service if it has a `eventSource:true` I've told the IBM Block chain for the starter option which is 1.1.0 to not put in the eventUrl but I'm sure they didn't listen
aatkddny (Fri, 04 May 2018 01:45:25 GMT):
In the config I was copying there's always an eventUrl. As an aside, the sdk load code was failing if eventUrl is null.
I had to add both it to the config and open port 7053 on my peers before it worked.
There's also no eventSource property anywhere in the BMX return, but I for sure get both hub and peer events there. Had to write filtering code for exactly that issue.
The only thing that might be throwing mine off is when I create the channel I don't set *all* of my peers as `po.setPeerRoles(allPeerRoles());` I'd expect the ones I did to get events, but no go there. I think I'll try futzing with that to turn it on everywhere and see if that changes anything.

aatkddny (Fri, 04 May 2018 13:38:27 GMT):
Well it turns out that I have to connect all the participants to all the channels up front otherwise I miss events, something I hadn't even considered until this juncture so it was a useful exercise purely from that perspective.
I turn the network config into a java object to "fix" some of the problems before converting it back so I do it from there, but as a really nice to have feature from my perspective, all the channels for an org is more useful by far. What would be totally awesome of course would be a way to prime the pump - connect to everything for that org - automagically.

The other one that would be super useful would be all the members associated with a channel, but that's probably a bit specialized - we can load chaincode across orgs and this would simplify that process.

And BMX doesn't send out the flags - which took me some work to figure out where to shove them (I initially thought they were properties) - so the newest change will have it responding to the event hub url but not to issue peer events. This is a change from a couple of weeks ago. I don't really care now I know how to set it, but wondered if it was intended behavior.

So here's a conundrum.
Say I have a channel with three organizations A, B, C and two sets of chaincode - CC_AB and CC_BC.
Endorsement policy on CC_AB is A and B, and on CC_BC it is B AND C.
How should that be represented in a NetworkConfig for B so that the correct peers are invoked to endorse? It's simpler for A and C since they only need access to one set of CC, but I'm not sure the correct way to do it (other than manually) for B.

Don't get what you're _fixing_. Yes as stated I informed the BMX team for 1.1 they should not be including the eventUrl and should include a endorsingPeer role. Also stated that it probably went nowhere.
I'm not aware the NetworkConfig aka Connection Profile address endorsements needed on chaincode. To me it is a failure to even have any mention of chaincode at all as it is static document and chaincode is too dynamic
Version 1.2 of the SDK via service discovery will figure out a lot of the _Network_ for you and when you want to invoke chaincode it will determine what endorsers are needed. I was hoping it will tell what chaincode you can invoke to but that's still _iffy_ Basically the only thing the Network Config will be useful for is the CAs in the Network and probably which Peer(s) should be used for the initial service discovery.

The CA cert is wrong.
Also have to put in sslProvider and negotiationType into grpcOptions all over the shop or it choked.

I think FAB-9267 covered the latter, but it's been a couple of weeks since I went back and looked at it.
rickr (Fri, 04 May 2018 22:15:27 GMT):
sslProvider and negotiationType for the most part should never need any explicit setting at all anymore. They default to openSSL and TLS with config properties to change that default. Not aware of any issue with CA cert either.
rickr (Fri, 04 May 2018 22:21:13 GMT):
The most likely thing that would need tweaking are the connection properties there have been methods added to the NetworkConfig to get/set them.

Guess I should move to PeerEventing anyway since thats the preferred approach now. Btw, whats the major advantage with this? One is obviously that I need to open and connect to a single port instead of requiring a separate one for events, but anything else?

When I use .thenApply on sendTransaction as per the integration test examples, I get a compile error on ".thenApply" saying

My code is:
`channel.sendTransaction(successful, newChannel.getOrderers()).thenApply(event -> {

I'm having to end up assigning the response to a variable of CompletableFuture and then doing .get(time).getTxId() instead which isnt ideal.

Is devMode available in Java SDK?
gravity (Thu, 10 May 2018 13:00:39 GMT):
Hello
Can someone help me to understand the difference between users(created via sdk) and peers?
For example, there is an org0 with two peers (crypto materials are generated by fabric-ca).
If I create a new user using sdk, should I run a new peer for this user? Or I missunderstood the difference between users and peers?
rickr (Thu, 10 May 2018 13:39:07 GMT):
There is no devMode in the sense of running the CC locally for quick testing. There is that capability with the command line . @sanchezl should be able to help

rickr (Thu, 10 May 2018 13:48:34 GMT):
Cryptogen provides a ChannelAdmin and PeerAdmin. The channel admin can create and update the channel itself. The PeerAdmin can join the peer to the channel, update peer organization and install instantiate chaincode on the peer they're an admin on.
There is another _Admin_ that is more appropriately should be considered to be a certificate authority registrar. With regard to the channels and peers this user is just a _regular member_ except with the certificate authority can register additional _regular members_.
These _regular members_ can invoke/query chaincode.
gravity (Thu, 10 May 2018 13:59:00 GMT):
@rickr
suppose I've registered a new user and later enroll this users. As a result I retrieved an Enrollment object with keys and certs. Should I store these keys and certificates in a separate storage? Or it better to enroll a user each time I want to invoke/query chaincode?
rickr (Thu, 10 May 2018 14:01:53 GMT):
that's up to your application choice

yeah... i can explain what it means @gravity
yacovm (Thu, 10 May 2018 15:14:18 GMT):
so, imagine you have a root CA that has under it an intermediate CA
yacovm (Thu, 10 May 2018 15:14:24 GMT):
lets call the root CA - rCA
yacovm (Thu, 10 May 2018 15:14:30 GMT):
and the intermediate CA - iCA
yacovm (Thu, 10 May 2018 15:14:46 GMT):
now, in fabric - any client certificate must be issued only by iCA and not by rCA
yacovm (Thu, 10 May 2018 15:14:59 GMT):
so, in other words- if you have a tree of CAs
yacovm (Thu, 10 May 2018 15:15:13 GMT):
then all client or peer identities must be issued by the leaf CAs ;)
gravity (Thu, 10 May 2018 15:16:27 GMT):
now it makes sense. I've used a root CA to register and enroll a user.
thanks for the explanation, very helpful :)

I was struggling with my below queries. My queries might be silly. Please bear with me.
1.When a peer will be added at runtime then how to create the docker container for that and bring it up.Do we need to update the docker-compose.yaml file and run it again?
2. Is there any way to generate channel tx file from java sdk or we can only create it via configtx tool?
Thanks in advance

If I understand correctly this sample, you can create a channel via SDK

rjain0701 (Sat, 12 May 2018 13:17:56 GMT):
@gravity Thanks for your reply. I have already run this test case. We can create the channel for which we already have the tx files. Let say if I need to create channel at run time then we I need to generate tx file first and then run the channel code from java

@gravity When I am creating a new channel for which tx file is not present. Then it gives me a exception that corresponding tx file is not present. Please le me know if I am missing any of the step

Hi
I am trying to use hyperledger fabric java sdk
I am following the steps at https://github.com/hyperledger/fabric-sdk-java
To run the integration tests, I run the command "mvn clean install -DskipITs=false -Dmaven.test.failure.ignore=false javadoc:javadoc" . I get the following error: Failed to execute goal org.apache.maven.plugins:maven-failsafe-plugin:2.19.1:verify (failsafe-integration-tests) on project fabric-sdk-java: There are test failures.

Hello
Is it possible to create a new Organization via SDK?
aatkddny (Tue, 15 May 2018 14:18:34 GMT):
yes
aatkddny (Tue, 15 May 2018 14:18:46 GMT):
you need a peer that uses the orderer crypto
aatkddny (Tue, 15 May 2018 14:19:48 GMT):
then add it into the genesis block using this as a pattern:
``` private void addMemberToConsortium(String consortium, String msp, Map config, Map configJson) {
Map x = (Map) config.get("channel_group");
Map x1 = (Map) x.get("groups");
Map x2 = (Map) x1.get("Consortiums");
Map x3 = (Map) x2.get("groups");
Map x4 = (Map) x3.get(consortium);
Map x5 = (Map) x4.get("groups");
x5.put(msp, configJson);
}
```
gravity (Tue, 15 May 2018 14:40:46 GMT):
thanks for a help.
there is one more question: how to add a new organization to a network without joining existing channels? the case is to create new org in an existing network, create a new channel and join org from the previous step to this channel
gravity (Tue, 15 May 2018 14:41:37 GMT):
actually, I'm wondering is it reasonable to create single org channels?
aatkddny (Tue, 15 May 2018 14:59:20 GMT):
you need to put it into the consortium before you can create a channel for it.
aatkddny (Tue, 15 May 2018 15:01:27 GMT):
ok so i'm missing something silly. anyone hit this?

This is on a second machine. Same code works on my local machine.
I reinstalled the latest set of docker containers and binaries.
It has a build of the latest sdk 1.1.0-SNAPSHOT in the local maven repo.
did a local go install of the latest grpc (which I'm not convinced was necessary)
it still throws this exception. what did i miss?
rickr (Tue, 15 May 2018 15:15:11 GMT):

how about the chain function called (e.g., "invoke")?
rickr (Tue, 15 May 2018 20:22:27 GMT):
the setFcn ? that just comes out as an argument
```
Transaction action 1 has 4 chaincode input arguments
Transaction action 1 has chaincode input argument 0 is: move
Transaction action 1 has chaincode input argument 1 is: a
Transaction action 1 has chaincode input argument 2 is: b
Transaction action 1 has chaincode input argument 3 is: 100
```
jtrayfield (Tue, 15 May 2018 20:30:36 GMT):
for example, my first txn (block 1) is:
jtrayfield (Tue, 15 May 2018 20:30:37 GMT):
Channel = mychannel
Timestamp = Mon May 14 19:50:51 UTC 2018
TxId = 9bcfa18c29ba724937cbf302571feb76e1a50d082f9c7ce79341a2bfcc1668b3
type = TRANSACTION_ENVELOPE
Command = deploy, mychannel,
@
&github.ibm.com/xxx0.0.1
init,
Org1MSP
Org2MSP
Org1MSP
Org2MSP,
jtrayfield (Tue, 15 May 2018 20:31:20 GMT):
so I need to distinguish between deploys and invokes.

@jtrayfield when you `deploy` the transaction action with have a chaincode name of `lscc` the fist argument should be deploy , the next is the channel , then is the `ChaincodeDeploymentSpec` this is a serialized protobuf
`org.hyperledger.fabric.protos.peer.Chaincode.ChaincodeDeploymentSpec`
you need to deserialize it. Chaincode.ChaincodeDeploymentSpec.parseFrom()

Hi all
How to give an access to the channel (to read/update) for a particular user (registered and enrolled using fabric-ca) in Hyperledger?
gravity (Wed, 16 May 2018 18:20:17 GMT):
Hi @rickr
is it possible to restrict chaincode invocation for particular users?
I mean, if there is an organization, with 4 peers, peer0 and peer1 are in channel A, peer2 and peer3 are in channel B.
there are 4 users registered with fabric-ca. is it possible to allow user0 and user1 to have an access only to channel A, and user2 and user3 to have only an access to channel B?
Thanks in advance

Hi, i'm trying to set custom message in pb.Response when i return result from my chaincode(i don't use shim.Success, instead i use pb.Response). For example when chaincode return response with Status=200 i see that on Java SDK side message is always OK and message set from chaincode is missing. Is this correct behavior, bug or i'm missing something here?
Also, i tried to extend 'error handling' in the chaincode and for example return status=404 in case when some asset can't be found. But, JDK always set status=500(on ProposalResponse object) and message contains 404 but it contains other stuff, looks like this:
Sending proposal to peer failed because of: gRPC failure=Status{code=UNKNOWN, description=chaincode error (status: 404, message: {"code":500,"message":"Asset does not exist for id =: 1122334455"}), cause=null}
I was expecting ProposalResponse status (ChaincodeResponse.Status) to be set to UNDEFINED because chaincode return 404.
amolpednekar (Fri, 18 May 2018 05:38:54 GMT):
Whenever I make any transaction with JSDK (I'm guessing this'll also happen with the NodeSDK), the peer logs show this
```

Hi all, I'm a new comer to Fabric. I'm done with "Byfn.sh" example and I tried to start with Java Sdk. But I was stuck with the usage of client. I have created a channel "mychannel" by "byfn.sh", how to use this channel in Java code? I only found "newChannel", "loadChannelFromConfig" which api creates a new channel. I tried with "getChannel" but it didn't work, so which one should I used? Thanks a lot in advance!!!

kiattchaip (Mon, 21 May 2018 10:50:43 GMT):
@rickr Thank you for the SDK v1.1.0, especially the FAB-8842. It really helps me out. However, I have a question about transaction status. In case I get ExecutionException or TimeoutException from `channel.sendTransaction(responses).get(5000L, TimeUnit.MILLISECONDS)`, I now fix it by getting the transaction status from TransactionEvent (when the cause of the ExecutionException is TransactionEventException) or querying it from peers but what If I can't get the TransactionEvent or find it on any peer, how can I get the transaction status? Can I check that the transaction was already placed on the orderer and will finally be sent to the peers?
rickr (Mon, 21 May 2018 11:13:49 GMT):
If you get an exception that is not a timeout either it didn't get on the orderer or the peer committers marked it bad. The most likely reason for getting a timeout is the peers your listening for the transaction has failed. In a high fail over recovery requirement you should have more peers that your application can query to see the status of the transaction.
rickr (Mon, 21 May 2018 11:16:38 GMT):
@amolpednekar Isn't the lambda expression used in the integration tests and compile and work ? How is yours different ?
kiattchaip (Tue, 22 May 2018 03:33:14 GMT):
@rickr So, I can assume that the transaction will be invalid or not happen if I get an exception that is not a TimeoutException right?
kiattchaip (Tue, 22 May 2018 03:33:14 GMT):
@rickr So, I need to check transaction status from available peers if I get a TimeoutException and I can assume that the transaction will be invalid or not happen if I get an exception that is not a TimeoutException right?

rickr (Tue, 22 May 2018 12:56:46 GMT):
Barring any bugs I think that's generally true. If you're application needs to be certain of any transactions completion/status and the cost to query for the transaction can be tolerated it would probably best to do that for additional checking.

createNoEvents ? If all you want is to send it to the Orderer and don't care about when/if transaction is completed.

rickr (Wed, 23 May 2018 19:23:42 GMT):
I think the difference here is that verify=false turns on allowAllHostNames So all this avoids is the checking of the CN matches the hostname in the certificate. But I think what you might be seeing as the cert is being signed by a CA or no CA at all that it trusts.

So now I'm really confused.
I had an ID10T error - I was using my admin id instead of my peer admin id to try to connect to the channel.
The reason I did that was because I was extrapolating from the loadChannelFromConfig code I had for BMX, where I don't have a peer admin and I needed to stick something in there to get round the null user context issue. I've totally switched it around. From being unsure why my local wasn't working, now I have no idea now why the remote call works with the "wrong" user.

Hi all
to send a transaction via sdk, should I send it to all peers or it can be any single peer?
kiattchaip (Thu, 24 May 2018 08:02:13 GMT):
@gravity A transaction (proposal responses) will be sent to an orderer, not a peer or peers. For a transaction proposal, it depends on the endorsement policy. You don't need to send it to all peers but it isn't wrong to do that. Just meet the number of peer specified the endorsement policy is enough to make the transaction valid.

You were 100% right - I missed the most obvious thing possible. I had the wrong spring profile - which meant that I was pointing to the wrong database and so the wrong set of saved user credentials. Trying to connect to a local instance with users saved with the non-local certs doesn't work. :rolling_eyes:

@gravity no you can't generate channel tx to create the channel The readme.md states how the ones the SDK uses was created.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=6MGG6unpydhtzG46x) @gravity
Well you kind of can if you hack it and use a ProcessBuilder to run configtxgen
Something like this - `String command = String.format("%s -profile %s -channelID %s -outputBlock %s", CONFIGTXGEN, genesisprofile, genesischannel, genesisfilename);`
That one will build the genesis block for the network if you set the variables appropriately and stick it in here `ProcessBuilder pb = pb(Paths.get(fabric, channel)).command("sh", "-c", command)`.
There's a bit more to it - setting up the environment and deciding how to handle logging - but it does work.
You can do all the crypto the same so you can do everything from a java app if you want to go to all the trouble.

actually, channel creation via sdk doesn't work if admin is enrolled via fabric-ca client. orderer responds that `0xc4201f67c0 identity 0 does not satisfy principal: This identity is not an admin`

1. use `hfClient.newChannel(String channelName)` with single param. it retrieves a channel object and then you can add peers(that joined that channel previously) and orderer:
```
channel = hfClient.newChannel("mychannel");
channel.addPeer(peer);
channel.addOrderer(orderer);
channel.initialize();
```
2. login into peer container and user `peer channel list` to list channel where that peer participates

Why peer container tries to find Go files in /opt/go directory?
aatkddny (Tue, 29 May 2018 15:53:20 GMT):
that's in the container. go is served from GOPATH which defaults iirc to that. Have a line in your peer volumes like this - `- {CHAINCODE}:/opt/gopath/src/chaincode/` to set it to a local path
aatkddny (Tue, 29 May 2018 15:53:39 GMT):
{CHAINCODE} obviously being the local path

this will work if you instantiate a chaincode from a container

Hi all.
Stuck with this error. peer cannot locate a chaincode source even if I mount chaincode source folder to a peer container: `${CHAINCODE_DIR}:/opt/gopath/src/chaincode`
Any suggestions?
Thanks in advance

It makes sense If we use abac example where the vendor folder presented.
But I tried another example and getting the same error.

make your directory path inside the zip "src" like this `Path src = Paths.get("src", ccid.getPath());`. It automagically does the rest for you.
aatkddny (Wed, 30 May 2018 14:08:26 GMT):
Go has a peculiarity where it adds the "src" to stuff.

You can only register a user once. There's a setting on the Fabric CA on the limit on how many times you can enroll

rickr (Tue, 05 Jun 2018 11:36:13 GMT):
@akoenig I don't know of a way to delete the actual channel. The integration tests simply recycle fabric docker containers which just wipes everything.

but there is no option for this, because the client is new and the orderer can't give me the info because it's private and and not public
rickr (Tue, 05 Jun 2018 11:40:06 GMT):
the very same channel ?
akoenig (Tue, 05 Jun 2018 11:42:24 GMT):
My idea was to have an init method for the channel in the UnitTests (Because i can't delete it). To look if there is already a channel with this name
akoenig (Tue, 05 Jun 2018 11:43:16 GMT):
but when the client is a new instance there is no channel on this client (correct), but the orderer HAS already this channel (see the correct error above) but i can't get this info, because the method is not public
akoenig (Tue, 05 Jun 2018 11:43:21 GMT):
or am i wrong? :)
akoenig (Tue, 05 Jun 2018 11:44:19 GMT):
my UnitTests in Java are in a random orderer thats why i need to this

Integrations test store the channel in the sampestore you could do the same. Check if it's in there

rickr (Tue, 05 Jun 2018 11:49:05 GMT):
If all you're asking is reconstruct the channel on the client side.
akoenig (Tue, 05 Jun 2018 11:52:10 GMT):
I will have a look at this
akoenig (Tue, 05 Jun 2018 12:10:59 GMT):
@rickr okay, for the first Implementation this will do the trick, thanks.

I'm trying to invoke a chaincode but getting an exception:
`Caused by: org.hyperledger.fabric.sdk.exception.TransactionEventException: Received invalid transaction event. Transaction ID 54cb3b8795144a1ca775bab0555369a1c62b1e82c955fe5ee9da8bd72aa8ddb9 status 10`

Any suggestions?

Hi @rickr
could you please explain what transientMap means for query/invoke requests?
```
Map tm2 = new HashMap<>();
tm2.put("HyperLedgerFabric", "QueryByChaincodeRequest:JavaSDK".getBytes(UTF_8));
tm2.put("method", "QueryByChaincodeRequest".getBytes(UTF_8));
```
Thanks in advance
rickr (Wed, 06 Jun 2018 12:28:39 GMT):
You can pass any data/parameter you want to you chaincode without it showing up in the ledger like arguments do showing what invoke the chaincode.

Anyone come across an issue where things start having problems when you increase the number of channels in a single peer? In this case it isn't even that many - there's about 20 or so.
This is mature code - it's been working for weeks. Literally the only change is to my internal configuration file to up the number of orgs and the number of channels.

Hi, based on the E2E-Test i want to install a second chaincode. So I created a new .go-file and have written some methods. The installProposalRequest has a directory of the go-path
akoenig (Fri, 08 Jun 2018 10:59:41 GMT):
if (isFooChain) {
// on foo chain install from directory.
installProposalRequest.setChaincodeSourceLocation(Paths.get(TEST_FIXTURES_PATH, CHAIN_CODE_FILEPATH).toFile());
akoenig (Fri, 08 Jun 2018 11:01:13 GMT):
(thats from the E2E-Tests example) and then i set the installProposalRequest.chainCodeName to one of these files. But it has no effect. How can I install different chaincodes? Or must they placed in different folders?
akoenig (Fri, 08 Jun 2018 11:04:10 GMT):
and when both files are in the same folder i get exceptions like Error returned from build: 1 "can't load package: package github.com/example_cc: found packages test (minting_example_cc.go) and main (move_example_cc.go) in /chaincode/input/src/github.com/example_cc
akoenig (Fri, 08 Jun 2018 11:04:36 GMT):
so is there a way to install more than one chaincode on the peers with the current sdk?
aatkddny (Fri, 08 Jun 2018 12:51:28 GMT):
trying to load a bunch of data into a channel to use as reference data. the app doing the load is single threaded and it brought to light something i hadn't considered.
this particular job is literally persisting k,v as strings - which get cast to byte[] in the go chaincode, so it couldn't be much simpler. v is small - less than 500 bytes of text.
the r/t time is around two seconds. which makes it seem like the put to the orderer is waiting until the next block is cut until it returns.
it's not the end of the world, but it will change how we think about writing to the blockchain at scale - lots more threads than we first thought.
has anyone else noticed this or did i manage to mess up my (very simple) test somehow.
rickr (Fri, 08 Jun 2018 13:44:57 GMT):
Is that just the time to put it on the orderer itself ?
aatkddny (Fri, 08 Jun 2018 14:23:00 GMT):
No that's the total R/T. The time sending to the orderer is here - it's a little less than 2.1s so the vast majority of the time. Don't worry about the names, they've been obfuscated

No that's the total R/T. The time sending to the orderer is here - it's a little less than 2.1s so the vast majority of the time. Don't worry about the names, they've been obfuscated, the two log messages from InvokeFabric are around the `TransactionEvent te = channel.sendTransaction(successful).get(invokeTime, TimeUnit.SECONDS);` call.

@rickr hi rick, I have deploy a distributed network in docker swarm, and started the application, but if there have no transaction for a while the eventhub could not received the event any more, is there any config could set the keep alive for the eventhub?

@rickr hi rick, I have deploy a distributed network in docker swarm, and started the application, but seems the eventhub would lost the connection if there have no transaction for a while, how can I debug this? BTW, I have already set the keep alive param for the eventhub when I construct it.

So I spent a few minutes adding a line or two to the camel route that's invoking the fabric to do this particular processing to run in parallel. It looks (to me at least) like it doesn't return until a block is cut.
I see a steady procession of puts to the orderer as one would expect, and every couple of seconds a rash of completions for everything from the last couple of seconds.
Just something to be aware of if anyone is trying to push data in at scale...

rickr (Tue, 12 Jun 2018 12:28:13 GMT):
@aatkddny There is a batch time out .. The orderer will wait that number of seconds before cutting a new block. Discuss on #fabric-orderer channel to discuss the consequence of tampering with that. Can you move off of eventhub and use the peer eventing services ?

So here's the rub @rickr. I *am* using peer eventing.
I don't actually want the event hub stuff, I just get it as part of the fabric.
The `CORE_PEER_EVENTS_ADDRESS=127.0.0.1:7053` hack causes connection reset exceptions in the SDK whether I suppress the 'eventUrl: ' value in the networkConnection json or not.
Since this is in the peer rather than the client, the `"eventing" : false,` flag does nothing other than mean I don't get the messages. Which I don't want anyway.

There's also the little matter of getting same in BMX for parity. But I'll set that aside from this conversation.
The code runs fine sin gee threaded. It runs fine with 10 threads. When I step it up to 200 it blows itself out of the water after a couple of seconds. It's likely some form of buffer/queue overflow and I have a lira in for it so since this is test code I'll restrict the load until there's a better solution

@vijay5378 You need to CA TLS certs setup when you create the HFCAClient you do that with properties `pemBytes` or `pemFile` if you're just testing and your certs dont have the correct CA Name you also need to add a `allowAllHostNames` property
vijay5378 (Tue, 12 Jun 2018 12:46:02 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=xB6broEfKngiCM9jF) @rickr Thanks for the response. I have passed ca-cert.pem through a Properties file to HFCAClient while setting up (I copied it over from the fabric-ca server). CA does have TLS enabled. In the meantime, I have written a java program (without using tomcat) and it seems to work fine. I am encountering this issue only when I call caclient.enroll from within a servlet. Also, where do I need to set allowAllHostNames? In the fabric-ca-server.yaml file?
rickr (Tue, 12 Jun 2018 12:51:13 GMT):
@aatkddny Maybe not following .. but let me ask: In the neworkConnection profile to get JUST the peer eventing service you should have NO `eventUrl` set at all and have `eventSource: true` set on the peers. Does that not work ?
rickr (Tue, 12 Jun 2018 12:53:03 GMT):
@vijay5378 `allowAllHostNames` set to true as a property just like pemBytes and pemFile
rickr (Tue, 12 Jun 2018 12:59:10 GMT):
@rahulhegde Only thing that comes to mind off the bat is you're not using the correct pemFile or pemBytes needed for TLS negotiation. For IBM JDK you also need to define some Java properties. It's documented in the README.md

That doesn't work because the problem is in the peer, not the client.
There's a hack for the peer - as I said before but probably with too much brevity - that points the event address to localhost which is supposed to suppress the peer problem.
It does appear to stop the initial error in the peer docker logs, but then the java client starts erroring out, regardless of the combination of event*** properties I set in the network config that I produce to allow same client application to connect. By that time I gthrew my hands up and set threadCount=10 and let it run for a couple of hours.

Regardless of whether it is there or not though, the java client starts erroring out, regardless of the combination of event*** properties I set in the network config. Meaning whether eventUrl is there or not and whether eventSource is set true or false.

this may be obvious - but it screwed me over for a while till I traced the code. You need to set the "true" in `allowAllHostNames` as a String `"true"` rather than a boolean `true` or it doesn't work

@deep123 Is this running the SDK's integration tests with the provided docker-compose ? Running on the same system ?
amolpednekar (Fri, 15 Jun 2018 07:02:22 GMT):
Not sure if this is the right channel to ask, but I was trying out IBM Blockchain Platform starter plan, and set up a network with 2 orgs.
Was able to register, enroll users with the registrar and invoke, query chaincodes
But how to get Peer admin keystore/certs so that I can instantiate/upgrade new chaincodes? Didnt find any such info in the connection profile
@aatkddny
akoenig (Fri, 15 Jun 2018 08:51:05 GMT):
@amolpednekar the E2E-Test from the example creates a user, set the usercontext to the channel. then you can instantiate the chaincode
akoenig (Fri, 15 Jun 2018 08:51:18 GMT):
on the channel/peers of the channel

akoenig (Fri, 15 Jun 2018 11:27:28 GMT):
in which folder do you execute the the make comand?
rickr (Fri, 15 Jun 2018 12:27:05 GMT):
@MeghaGupta Please follow the README.md provided. You don't need to just starting out run `configtxgen` . A function fabric network is already set up for the integration tests which you can follow to see the SDK in action.

@rickr Is the GA date for the 1.2 SDK (as opposed to pulling a snapshot) the same as for the base Fabric - the 18th iirc?
kesavants (Fri, 15 Jun 2018 14:12:53 GMT):
It seems you cannot add peer to org.hyperledger.fabric.sdk.Channel once it is initialized. When a new organization is onboarded to existing network do we have to recreate the channel object again ?

@gravity yes: you need to provide more information. Look at the Orderer logs too.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=yD882p4A8aaZXwYoZ) @rickr Thanks @rickr. Is the orderer genesis block mandatory? If yes, would I need to use configtxgen for that alone? Any reason why it is that way? I am trying to build a web app where the channel can be created automatically once the crypto files are being generated. Any workaround/tips would be great
rickr (Mon, 18 Jun 2018 13:04:09 GMT):
The README.md states how it was created. If there was a way to do it I would have provided an example in the integration tests. The means to do that can be have your webapp invoke the fabric commands. Many argued that the SDKs should not do any channel/peer administration at all. In hindsight I'll admit that they were probably right.
vijay5378 (Mon, 18 Jun 2018 13:08:20 GMT):
@rickr thanks for the answer. Though I do not understand the rationale behind why the SDK shouldn't do channel/peer administration, I am sure you guys would have had a very valid reason. I will do as you suggested and invoke the fabric command using the webapp.

Hey I'm having trouble instantiating chaincode via the java sdk.
I keep getting the following error:
instantiation policy violation: signature set did not satisfy policy
The requesting user is the CA-Admin and should most definitely have permissions to do so.
We tried it with the default chaincode endorsement policies and changed them to even accept any member. Really tried a lot of different things and none of them seemed to work.
Help would be appreciated
IgorSim (Tue, 19 Jun 2018 07:30:12 GMT):
@tinytiny123 i'm not sure but perhaps you need Peer Admin (and not CA-Admin) to execute 'instantiate' command?
kiattchaip (Tue, 19 Jun 2018 07:49:56 GMT):
IgorSim is right. The use who has the right to install and instantiate chaincode is PeerAdmin.

IgorSim (Tue, 19 Jun 2018 07:57:33 GMT):
I have one question about 'setUserContext()' method defined on HFClient and TransactionProposalRequest. I have network with two orgs, and i used ORG admin from ORG1 during channel initialization. When sending trx. proposal using ORG admin from ORG1 it works fine but when i switch to ORG admin from ORG2 (transactionProposalRequest.setUsercontext(ORG2 Admin user)) i see 'forbidden' error reported by the orderer. It looks like i must use same user that i used during channel init. I don't think its policy issue because i use default policy that grants write permissions to every ORG Admin user. Perhaps something is mixed up on my side..i just wanted to check if switching 'user context' should work fine

@rickr In the integration tests, why do we not override hostname for CA cert?
Instead they're set to allowAllHostNames? As opposed to orderer, peer where we set hostNameOverride to CN of their respective certs?

@IgorSim It's not realistic to have two admins from different orgs using the same channel object in the same application. See https://github.com/cr22rc/fabricSDKJavaMultiDomainSample
rickr (Wed, 20 Jun 2018 11:59:41 GMT):
@amolpednekar difference is in how Apache HTTP client and GRPC client expose that feature.

Hi guys! I hope I will be able to find some answers here regarding mutual TLS between Fabric CA server and fabric Java SDK client app
diyan.filipov (Wed, 20 Jun 2018 13:21:58 GMT):
More precisely - I have a configured CA server with TLS enabled which I am able to reach via curl (providing the --key & --cert files configured in the ca-server config). But I saw that I am not able to configure and use a CA client from the Java SDK with client key and certificate, because the configuration section in `certificateAuthorities.caName.tlsCACerts.client` keyfile and certfile is not read at all from the NetworkConfig - `org.hyperledger.fabric.sdk.NetworkConfig#getTLSCerts`. So I guess mutual TLS from the SDK is not possible for now or there is some workaround you guys could point me to?
Furthermore, if I don't use the `NetworkConfig` class to load my configs and use Properties to init the `HFCAClient`, again, it is not possible to pass the props needed for mutual TLS, because HFCAClient supports only `pemFile` and `allowAllHostNames` properties (check the `HFCAClient` constructor java docs)
Marc.K (Wed, 20 Jun 2018 13:37:26 GMT):
Hey
I'm currently setting up our project with the Java SDK and I'm having problems understanding how the Channel object is supposed to be used. Let's assume I set up a channel for two orgs and install & init some chaincode on it. Now how does the second Org connect to the channel? I only found the reconstruct function within the NetworkConfig class. Would I have to provide the channel configuration as JSON to the other org for them to use the channel?

All request include credentials of the user to be authenticated using TLS server side only to make sure it's not in clear will make it secure. Mutual TLS won't provide that much of an added benefit.

Hello!
I want to dynamically create a new channel so 2 users that i have created can share info between them, that is possible without generating the .tx when the network is created?
diyan.filipov (Thu, 21 Jun 2018 14:20:08 GMT):
@rickr Thanks for the info. I just got mislead by the docs and configs in the CA server and in the java SDK which got me thinking that mutual TLS is possible. Please make sure to remove `certificateAuthorities.caName.tlsCACerts.client` keyfile and certfile` from the yaml configs as they are not currently supported. At the end, I was able to configure and accomplish a mutual TLS between the CA server and a fabric java client (with my own implementation of the HFCAClient). I would be happy to contribute the implementation :)

@amolpednekar The SDK currently does not know the endorsement policy .. All the individual endorsements may be just fine. But when they all go back via the Orderer each commiting peer see that the needed endorsement policy was not meet.
rickr (Mon, 25 Jun 2018 13:25:22 GMT):
@nikolas The hash of block itself is not in the block. The SDK has a way to calculate it as shown here : https://github.com/hyperledger/fabric-sdk-java/blob/edd54f832351452ef6aea3d9cb505b2f38b12711/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java#L900
rickr (Mon, 25 Jun 2018 13:33:25 GMT):
@dharuq Not sure I follow your question. The SDK itself does not create the orderer block nor the channel creation transaction. The README.md states how they were created for the SDK. To see how two organization would collaborate together look at https://github.com/cr22rc/BMXHyperledgerFabricJSDKIntegrationSample

I have two more questions:
1) To define access control policies I have to use Attribute-Based Access Control right? For that when I register a new user I have to do this: `rr.addAttribute(new Attribute("attr1", role, true));` right?
2) When the user is registered and enrolled for the first time and the applications is shut down and reconstrusted I reenroll the user. What is the reenroll method really doing?

@rickr yes, i want to move the method "getSignedPropsal" of the channel to some other service/interface like "signPropsal" so an other instance can sigen the propsal with the private key. So the network does not need the private key.

Question about the SDK implementation of Peer eventing.
I'm looking at improving the robustness of the stuff we have bolted onto peer eventing and need just a little clarification about the implementation in the SDK.
Without tracing the code, it looks like one gets an event inside the `ChaincodeEventListener` for each Tx inside a block for each peer that has eventing turned on.
If that's true is there a way to see that a block has been fully processed - meaning all the events for all the Tx inside it have been raised - or do I need to save down to the Tx level which ones have been sent?
And the second follow on is that apparently it's possible to set a start block for replay in case of failure.
Is that implemented? And if so is there an example of use anywhere?

The final part of the may be more a pure HL question - is the return order guaranteed. Think processing an order and revisions that then need to be applied in the order received.

@kesavants Check that all peers (excepts a peer role is set) you add to a channel are valid and connectable. After calling `channel.sendTransaction().get()`, the SDK will wait until a transaction (in a block) is added to all peers in the channel.

2. While it's replaying I too *hope* it remains ordered, but I have no idea whether the eventing model processes the blocks in parallel for efficiency - and as such may not be order preserving.
rickr (Fri, 29 Jun 2018 13:05:30 GMT):
@kesavants You'd need to enable trace. There are trace statements that say what events are being received. FWIW I just completed an eight hour run of multithread version of end2end scenario .. and seen no indications of events not being received.

There is also a _policing_ thread that runs periodically that looking for waiting transactions that are older then about 10 mins and cleans them up. This will print warnings for the peers/eventhubs that didn't report the event.
rickr (Fri, 29 Jun 2018 13:12:47 GMT):
@aatkddny The events should be processed as if you _started back in time_ :) There is one _subtlety_ I'll point out. Each chaincode event as they are encountered will be called back to any listener on it's own thread. So expect that you can be handling more than one thread at a time. :wink:

@kesavants No. I had considered providing the reverse at one point. I think it's less of a priority now given the direction is more towards using service discovery.

In fabric-ca java sdk, when a call is made to client.info().getCACertificateChain();, does it return the properly encoded pem file? I double checked and the returned certificate lacks the start "BEGIN CERTIFICATE" and "END CERTIFICATE" portion. Is it left to the user to create a proper pem certificate?

donsonZhang (Thu, 05 Jul 2018 09:35:05 GMT):
when i updating a Channel Configuration use java sdk, the BatchTimeout:timeout can be updated success and valid; but when i update BatchSize:max_message_count, also can be updated success,but not go into effect
donsonZhang (Thu, 05 Jul 2018 09:39:00 GMT):
example, begin the BatchSize:max_message_count = 10, and update it to 30, now the channel config is 30, but the block max message count is still 10
donsonZhang (Thu, 05 Jul 2018 09:39:53 GMT):
when i restart the orderer node , the new max_message_count=30 is valid
donsonZhang (Thu, 05 Jul 2018 09:40:27 GMT):
so update channel config for the BatchSize:max_message_count is a bug?

aatkddny (Thu, 05 Jul 2018 12:11:24 GMT):
Private data question. More one of style than anything else.
Looking at your example in the Go CC you've set the PD from the A and B values in the main parameter array.
I'm guessing (hoping) that was for expediency to test functionality rather than a coding example, as I *thought* one was to use the transient map for passing private data back and forth.
So my question is - are we supposed to be using the transient map for private data, or should it be extra parameter(s) in the main list?

@donsonZhang I've seen there is sometimes a delay. Can you try putting in a sleep of 10 secs or so and see if it gets updated. I think if it requires a reboot of the Orderer that should be brought to the attention of the people working on it. Try the #fabric-orderer channel.

vijay5378 (Mon, 09 Jul 2018 13:29:58 GMT):
@rickr The first issue (where the CA server was returning a different file) was resolved by decoding the returned string into a certificate. CA server was only returning a java encoded string. It might be helpful if a PEM to certificate was added to the sdk.
vijay5378 (Mon, 09 Jul 2018 13:35:06 GMT):
@rickr the second issue was because of tomcat and ALPN. I am having a servlet that tries to create a channel. This causes an issue - there are two ways in which it can be resolved. 1) Adding jetty-alpn-boot to tomcat's JRE bootstrap library (or) 2) setting tomcat's java to 9. I have tried option 1 and it seems to work. I did try to option 2 also, but I have got spotty results. In one test case, works fine, however, there were issues in another container. There also seems to be a problem with the versions - i have tested with grpc-all-1.1 and netty-all-4.1.22 with tcnative-boring-ssl-static 2.0.7 and with Java(TM) SE Runtime Environment (build 1.8.0_161-b12)

Looks like there is conflict between Spring Boot v2.0.x against this Java SDK due to dependency on snakeyaml v1.21 (which Java SDK uses).
https://github.com/spring-projects/spring-boot/issues/13191
Do you think it is safe to down grade to v1.19 which Spring Boot officially supports. Say all the configuration are passed using .json not .yaml file, then the code does not go through snakeyaml process.

Hi everyone! I have a question. I want to know how can I connect the fabric using fabric-sdk-java?
MeghaGupta (Wed, 11 Jul 2018 08:45:03 GMT):
@vijay5378 could you please give me more detail path of core.yaml . I am new to fabric-sdk. its inside hyperledger-fabric-sdk right ?
kolayuk (Wed, 11 Jul 2018 09:51:05 GMT):
@MeghaGupta i dont know where is core.yaml, but we're using env variables, it works ok. Refer to docs: ```You can also pass in docker environment variables to override core.yaml values, for example CORE_LEDGER_STATE_STATEDATABASE and CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS.```
rickr (Wed, 11 Jul 2018 12:02:27 GMT):
@vijay5378 peer admins should sign by the policy.
rickr (Wed, 11 Jul 2018 12:03:21 GMT):
@am yes should be able to use it. Probably should use the v1.2-SNAPSHOT only way you'll its working for you or bring up issues.
rickr (Wed, 11 Jul 2018 12:04:06 GMT):
@ibmamnt only test with current versions of dependencies but don't know of any issues.
rickr (Wed, 11 Jul 2018 12:04:59 GMT):
@kolayuk I would recommend using v1.2-SNAPSHOT. If you want v1.2 and see if you find issues.
rickr (Wed, 11 Jul 2018 12:06:10 GMT):
@MeghaGupta please ask on #fabric-questions . It needs to be documented somewhere.
MeghaGupta (Wed, 11 Jul 2018 14:12:54 GMT):
@kolayuk need little more help. I have given CORE_LEDGER_STATE_STATEDATABASE=CouchDB

Hey! Was trying out the v1.2 java sdk yesterday and ran into an issue with X.509 certificates on certain transactions. Top of the stack trace is: `org.hyperledger.fabric.sdk.exception.CryptoException: X.509 not found`
MikeEmery (Wed, 11 Jul 2018 15:55:23 GMT):
I'm using bouncycastle elsewhere for 509, is this just a matter of setting something for the jvm so fabric sdk can see it?

I have a scripted java process that stands up a fabric, from crypto through orderers to peers to creating channels to installing chaincode.
It was working. Until now. I just ran it and it's throwing this while trying to install chaincode. This isn't something I've seen before and I was wondering if anyone else ran across it.

can you resolve the hostname from the same machine the process is running on?
aatkddny (Thu, 12 Jul 2018 12:35:21 GMT):
Everything is local.

And I didn't turn off IP6 in the machine settings.

Do we have any other way then creating a plugin in go for plugging custom validation ?

but can you resolve or not @aatkddny ?
rickr (Thu, 12 Jul 2018 12:41:16 GMT):
Try putting on trace on the client see what it's trying to do It seems it trying to resolve `peer0.xxx.com` which is I don't is your intent .. or alternative just for a quick hackish add that to your hots file to resolve for localhost to just see that's what really happening
aatkddny (Thu, 12 Jul 2018 12:41:29 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=Wt7ABzQdJkLCXi9rL) @yacovm Sorry - I should have read your question properly. The hostname is internal to the docker cluster. I interact through localhost and an exposed port.
yacovm (Thu, 12 Jul 2018 12:41:43 GMT):
so obviously you can't do that...
yacovm (Thu, 12 Jul 2018 12:41:49 GMT):
you should try doing the following
yacovm (Thu, 12 Jul 2018 12:41:57 GMT):
edit `/etc/hosts` and add that peer
yacovm (Thu, 12 Jul 2018 12:42:03 GMT):
make it localhost
yacovm (Thu, 12 Jul 2018 12:42:06 GMT):
and then try again
yacovm (Thu, 12 Jul 2018 12:42:22 GMT):
oh that's what Rick said :)
aatkddny (Thu, 12 Jul 2018 12:43:23 GMT):
there are about a dozen of them. I interact through localhost and exposed ports. This is something inside the fabric - it's muttering about service discovery.
yacovm (Thu, 12 Jul 2018 12:43:50 GMT):
it's not inside the fabric... you can't resolve the hostname
yacovm (Thu, 12 Jul 2018 12:44:00 GMT):
I guess the previous version had an override

I don't assume you're trying to use service discovery .. maybe this is a bug that got injected
rickr (Thu, 12 Jul 2018 12:47:20 GMT):
@MikeEmery the x509 not found is most likely not likely to be the actual issue. There is buglet that when an error occurs the SDK
will still try to validate the response even though it was not signed. Look for other errors around that point.

You can see my localhost:port in there.
rickr (Thu, 12 Jul 2018 12:55:45 GMT):
Can you make sure where you're adding/joining your peers to the channel that you explicitly define their roles so they don't have a service discovery role

Is it a new default? I only have eventing/endorsing set true and filtering false. everything else is whatever the defaults are.

can you add some code once the channel is created to get all the peers and see what roles they actually have
rickr (Thu, 12 Jul 2018 13:20:32 GMT):
Should not go down the service discovery route if no peers have that role. But there could always be a hole I missed :scream:
aatkddny (Thu, 12 Jul 2018 13:28:53 GMT):
I clearly misunderstood. I thought you wanted the config when it was trying to install the chaincode. The create channel used a lovely piece of code that did this:
```
if (hp.isEventing()) {
po.setPeerRoles(allPeerRoles());
```
I'm sure you can guess what allPeerRoles() was. Forcing it off there so I got `[ENDORSING_PEER, CHAINCODE_QUERY, LEDGER_QUERY, EVENT_SOURCE]` means it now works again.
So If I may ask, can this be changed to default off at least until it's fixed?

Hello
are there any alternatices to `configtxgen` in java sdk to create channel configuration?
gravity (Thu, 12 Jul 2018 15:48:57 GMT):
the use case is to create channels dynamically with different names. and for this channel configuration file is needed. but to create it, we have to use `configtxgen`. but it's not a very convenient way as for me.
any suggestions?
thanks in advance
huy.tranibm (Thu, 12 Jul 2018 15:50:03 GMT):
you can make a channel config template and edit as needed

use configtxlator to get the channel config json

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=G2QCKLmYGqzzfpMKg) @huy.tranibm i've extracted the json config using this command `./configtxgen -inspectChannelCreateTx testchannel.tx`
if I modify this template, how to pack it back into tx file? or am I doing something wrong?
aatkddny (Thu, 12 Jul 2018 16:06:46 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=xE5gT9JekBbMHAata) If - as was suggested - you use a template, you can pass it through configtxgen to get the ccf by using a processbuilder inside the app.
```
StringBuilder sb = new StringBuilder(CONFIGTXGEN);
sb.append(" -profile ");
sb.append(channelProfile);
sb.append(" -channelID ");
sb.append(channelName);
sb.append(" -outputCreateChannelTx ");
sb.append(fileName);
log.debug("Calling configtxgen to create channel file for {}", channelName);
ProcessBuilder pb = pb(Paths.get(fabric, channel)).command("sh", "-c", sb.toString());

rickr (Fri, 13 Jul 2018 12:20:07 GMT):
@gravity If you closely follow this code (pay attention to comments) it does show setting endorsement and getting failures for incorrect endorsements depending on what is commented out.
https://github.com/cr22rc/fabricSDKJavaMultiDomainSample
It *may* at this point not work as I think I regenerated channel artifacts in the SDK and did not have time to update it yet.
AFAIK you can't directly access/modify chaincode variables from another chaincode. There is a way for one chaincode to execute another chaincode that could roughly accomplish something similar

Is there a recommendation as to best practices for using the SDK to pass private data in and out?
ISTR seeing something that said to use the transient fields, but the example just has it in the mainline code.

ISTR seeing something that said to use the transient fields, but the example just has it in the mainline code.
Then there's another one that has separate calls for private data and for regular on chain data.
It seems to be a bit ad hoc.
We are starting to think about this and were thinking we should separate the calls for PD and regular chain data and pass in the name of the PD collection as a property with the actual data as if it were a regular transaction.
Unless there's a standard way to do it.

But ok... If you say that's not a problem, its not a problem
yacovm (Fri, 13 Jul 2018 19:09:24 GMT):
You put transiwnt data into the chaincode - not back
aatkddny (Fri, 13 Jul 2018 19:15:25 GMT):
Right.
So in order to return private data, I have to return it as part of the return data in the transaction set.
Assuming there is any of course. And leaving aside any multiple collection complexity.
So to get it in there means I can
1. put it into the transient data - which means the api is asymmetric
2. add it as an extra property (or properties) to the main call
3.or have a separate call (or calls) for each pd collection that self-identifies the name of the collection.
My question was is there a recommended method - I don't want to do one flavor and then have to change it all because someone changed everything again in 1.4...
aatkddny (Fri, 13 Jul 2018 19:15:25 GMT):

Assuming there is any of course. And leaving aside any multiple collection complexity.
So to get it in there means I can
1. put it into the transient data and pull that out and save it - which means the api is asymmetric as I still have to return as part of the main object.
2. add it as an extra property (or properties) to the main call
3.or have a separate call (or calls) for each pd collection that self-identifies the name of the collection.

yacovm (Fri, 13 Jul 2018 19:16:42 GMT):
I think i'm not fully getting you... Lets go slowly
yacovm (Fri, 13 Jul 2018 19:17:00 GMT):
You want to do a query, or an "invoke"?
yacovm (Fri, 13 Jul 2018 19:17:22 GMT):
i.e - do you want to send the result to the ordere
yacovm (Fri, 13 Jul 2018 19:17:26 GMT):
?
aatkddny (Fri, 13 Jul 2018 19:17:33 GMT):
No. Let me try again.
aatkddny (Fri, 13 Jul 2018 19:19:18 GMT):
I am adding data to the BC. I'll call it an asset to save typing and to avoid mixed terms.
This asset has some private data associated with it. I need to get asset and private data into and out of my chaincode through the API to properly endorse a transaction.
aatkddny (Fri, 13 Jul 2018 19:19:54 GMT):
So with that as a given, is there a recommended way to use the SDK to pass this data back and forth.
yacovm (Fri, 13 Jul 2018 19:20:27 GMT):
So you put the private data via computing a function in the chaincode that is derived from the transient (for example)
yacovm (Fri, 13 Jul 2018 19:21:16 GMT):
To gettbe data out of the blockchain - you do a query and dont send the result to the orderer and the output is in the payload
aatkddny (Fri, 13 Jul 2018 19:22:00 GMT):
Well actually I was going to pass it in as a serialized map. Privacy here is slightly different from a general case.
yacovm (Fri, 13 Jul 2018 19:22:27 GMT):
Transient is a map 🙄
aatkddny (Fri, 13 Jul 2018 19:22:34 GMT):
I know.
aatkddny (Fri, 13 Jul 2018 19:24:32 GMT):
My private data will be turned into a map. It will be serialized and passed into the chaincode.
If I read you correctly you are saying pass it *IN* through the transient map and when time comes to read it get it *OUT* as the return object - just ignore the call to the orderer for the latter..
So I need to make two calls to get asset and private out, but one to get it in.
yacovm (Fri, 13 Jul 2018 19:25:23 GMT):
Why 2 calls?
aatkddny (Fri, 13 Jul 2018 19:27:33 GMT):
My bad - I hadn't looked at the query for a while. I -just- get the proposal response. It doesn't go to the orderer like the invoke does.
aatkddny (Fri, 13 Jul 2018 19:29:14 GMT):
One call, but in through transient and out through the return object then.
So my response object needs to account for extra data when compared to the one I put in.
aatkddny (Fri, 13 Jul 2018 19:29:14 GMT):
One call, but in through transient and out through the return object then.
So my response object needs to account for extra data when compared to the one I put in. Which is option 1 above I think.
yacovm (Fri, 13 Jul 2018 19:31:09 GMT):
I really dont understand what's the complaint about
yacovm (Fri, 13 Jul 2018 19:31:37 GMT):
So the way is assymetric.... So?
yacovm (Fri, 13 Jul 2018 19:32:21 GMT):
And it wont change in v1.4
aatkddny (Fri, 13 Jul 2018 19:33:43 GMT):
Because it's not intuitive and its inelegant. I need to wrap my responses now to account for the possibility that private data may be part of them, but I'm not to pass it in that way in the requests.
yacovm (Fri, 13 Jul 2018 19:35:58 GMT):
If think about how things work in the system and not how a pretty API would look like- it won't be weird to you 😉

aatkddny (Fri, 13 Jul 2018 19:39:51 GMT):
Nope. Not getting it. What am I missing?
The client (through the channel) calls the peers directly, no? So why can't the chaincode strip the private data out of the main asset before producing the response?
yacovm (Fri, 13 Jul 2018 19:40:33 GMT):
Because the response payload is a function of the chaincode computation
yacovm (Fri, 13 Jul 2018 19:40:50 GMT):
The infrastructure can't introspect it
yacovm (Fri, 13 Jul 2018 19:41:08 GMT):
Since it doesnt know what the computation did
aatkddny (Fri, 13 Jul 2018 19:42:33 GMT):
you lost me. i thought the output of the chaincode was a RW set. I didn't think the input was part of that output.
aatkddny (Fri, 13 Jul 2018 19:43:44 GMT):
So if the input isn't included, ought the chaincode not be free to take part of it and use it as private data while transforming the rest into regular data.
yacovm (Fri, 13 Jul 2018 19:43:47 GMT):
The output of a *query* isn't a RWset, thats just a byproduct
aatkddny (Fri, 13 Jul 2018 19:44:05 GMT):
not a query. i'm talking about sticking it into the thing in the first place.
yacovm (Fri, 13 Jul 2018 19:44:34 GMT):
I'm sorry but i just dont understand... Completely lost you
aatkddny (Fri, 13 Jul 2018 19:45:46 GMT):
i'm missing a key piece of information. i thought on an add of something to the ledger the only connection between input state and output state was contained in the chaincode.
aatkddny (Fri, 13 Jul 2018 19:46:01 GMT):
I didn't think that the input was propagated as part of the output.
aatkddny (Fri, 13 Jul 2018 19:46:01 GMT):
I didn't think that the input was propagated as part of the output.
aatkddny (Fri, 13 Jul 2018 19:47:01 GMT):
i thought the output was the set of data created by the chaincode. it's been a while since i looked at any so let me go find the call i'm talking about.
aatkddny (Fri, 13 Jul 2018 19:48:25 GMT):

shim.Putstate `err = api.PutState(fabricAware.ID, jsonBytes)`
aatkddny (Fri, 13 Jul 2018 19:48:25 GMT):
shim.Putstate `err = api.PutState(fabricAware.ID, jsonBytes)` plus - obviously - any of the other xxxState calls.
yacovm (Fri, 13 Jul 2018 19:51:14 GMT):
I didn't say the input was propagated as part of the output
aatkddny (Fri, 13 Jul 2018 19:52:41 GMT):
Right so then why can't the same object come in as go out. Why does the private data need to go in through transient?
aatkddny (Fri, 13 Jul 2018 19:52:41 GMT):
Right so then why can't the same object come in as go out. Why does the private data need to go in through transient? Given that the client calls the peers to endorse.
yacovm (Fri, 13 Jul 2018 19:53:13 GMT):
oh... because it's visible in the proposal
aatkddny (Fri, 13 Jul 2018 19:53:31 GMT):
But doesn't the proposal only go to the peers?
yacovm (Fri, 13 Jul 2018 19:53:46 GMT):
no... it's part of the final transaction
aatkddny (Fri, 13 Jul 2018 19:54:04 GMT):
So the input is *is* propagated.
aatkddny (Fri, 13 Jul 2018 19:54:04 GMT):
So the input *is* propagated.
yacovm (Fri, 13 Jul 2018 19:54:10 GMT):
not from the chaincode
aatkddny (Fri, 13 Jul 2018 19:55:05 GMT):
I'm conflating the whole chaincode:peer mess here. I don't care which bit propagates input to output, it's sufficient that it gets propagated.

i tried to setup node sdk for my blockchain application(single org and has only one peer), it is working.
As of now i am trying to setup two node js server's, one is for peer1 of org 1 and another one for peer1 of org 2.
i am ending up with the error,

i need some clarification and help on the these things,
1) Setting up of node servers for each peer should able to do. - please correct me if i am wrong.
2) If anyone has multi node server setup for blockchain application - can you please share it / guide on this.
I havent tried java sdk. But, I am trusting that somebody might tried both approaches
Can you people help on this if possible

Hi all
Why it's impossible to enroll an org admin (who can create channels and install chaincodes) via fabric-ca (using java sdk)?
I'm getting the certificates, but when I try to an admin action, I'm getting the errror that `The identity is not an admin`.

when the fabric java sdk 1.2 release?
donsonZhang (Tue, 17 Jul 2018 10:23:54 GMT):
the eventHubs and the getEventingPeers all can establish gprc to listen blockevent, so what the difference ?
donsonZhang (Tue, 17 Jul 2018 10:25:20 GMT):
and I found if not event peer,and only the eventhub, the invoke function can not recevice transactionEvent

rickr (Tue, 17 Jul 2018 11:10:29 GMT):
```The Fabric peer now implements eventing services on the same endpoint as proposal endorsements and it is no longer necessary to have an EventHub service. Using peer eventing is the preferred means for receiving events. Future releases of Fabric may not support Eventhubs.```
Adam_Hardie (Wed, 18 Jul 2018 13:07:41 GMT):
ChaincodeEventListener seems to be calling received() twice per transaction (when there is only one event per tx).. can anyone advise why this would be?
rickr (Wed, 18 Jul 2018 13:09:56 GMT):
You'll get an event for each eventhub and peer eventing service you have
Adam_Hardie (Wed, 18 Jul 2018 13:16:52 GMT):
okay thank you!
Adam_Hardie (Wed, 18 Jul 2018 13:39:12 GMT):
so going by the above, i can actually just not use an eventhub in this case, and just register an eventingpeer instead
Adam_Hardie (Wed, 18 Jul 2018 13:40:11 GMT):
im sure I only have a single eventhub, and a normal peer currently. will the 'normal' peer [channel.addPeer(peer);] cause events too?
Adam_Hardie (Wed, 18 Jul 2018 13:40:27 GMT):
when i say cause i mean call received()
Adam_Hardie (Wed, 18 Jul 2018 13:41:59 GMT):
apologies if that is cryptic :)
Adam_Hardie (Wed, 18 Jul 2018 13:42:25 GMT):
i just believe i have the most basic setup
channel.addPeer(peer);
channel.addEventHub(eventHub);
channel.addOrderer(orderer);
channel.initialize();
and then channel.registerChaincodeEventListener(
rickr (Wed, 18 Jul 2018 13:46:40 GMT):
Look at the blockEvent you receive there's a method getEventHub and getPeer on should always be null an the other the source of the event

What is the correct strategy to use HFClient with multiple users? Cache multiple instances? setUserContext for each call? Make disposable clients?
rickr (Wed, 18 Jul 2018 14:13:08 GMT):
@oborovyk You need to decide on how your application will use it. Let me point out that setting user context is not a thread safe operation. Instead if you plan on using multiple threads look at api that explicitly set thus override the usercontext set on the client.

hi, one question about channel (re)initialization. Let's say channel object is already initialized and in HLF there is new organization that has joined the network and network has been reconfigured. This means that channel should be reinitialized. Is it possible to modify already initialized channel (for example by adding peer(s) from the new org) or channel should be shutdown and initialized again ?
oborovyk (Wed, 18 Jul 2018 15:30:46 GMT):
+1. Also a problem to split the initialization and defer addition of event listeners. Is channel.initialize() idempotent ?

There are some minor bugs/enhancements looking at in that area but in *theory* there should be nothing the app should really need to do as long as the channel has an active eventing source or is using service discovery.

Hi, is there a way to get all functions of a chaincode? There is the class"ChaincodeInfo" but i can't get any methods from this class. E.g. in my ChainCode "foo" is a method "bar" with the inputs "xyz" and "zyx". Is there a way to get those infos?
akoenig (Fri, 20 Jul 2018 09:55:34 GMT):
I need this to give the user some information about the existing methods of the chaincode which he maybe wants to use
rickr (Fri, 20 Jul 2018 12:01:27 GMT):
I'm not the chaincode expert by far :) but I don't think there is a way to query running chaincode for what methods/parameters it supports ( _like Java reflection_ ). Probably better asked on #fabric-chaincode-dev channel.
rickr (Fri, 20 Jul 2018 12:02:49 GMT):
I've seen you've already done --- _please don't cross post same question on several channels!_
oborovyk (Fri, 20 Jul 2018 16:30:57 GMT):
Hi,
I can't find the code which stops the event listener thread(s) which are created in startEventQue() after channel.shutdown() or channel.unregisterBlockListener(). Is it a bug or am I missing smth?
Also if channel.initialize() is called twice it will lead to duplicated events.
rickr (Fri, 20 Jul 2018 17:03:54 GMT):
Should be no need to call initialize twice
rickr (Fri, 20 Jul 2018 17:06:12 GMT):
I think if you shutdown the channel it should stop all
oborovyk (Fri, 20 Jul 2018 17:19:55 GMT):
it should but it doesn
oborovyk (Fri, 20 Jul 2018 17:19:55 GMT):
it should but it seems it doesn't. There's client.getExecutorService().execute(() -> l.listener.received(blockEvent)); and only eventQueueThread.interrupt();. Would be probably better to have an executor service per channel
rickr (Fri, 20 Jul 2018 17:51:49 GMT):
I'll need to look closer .. but for shutdown all the block listeners are cleared. All eventhubs and peers that would be generating the events are also shutdown. Not sure how the channel would still be generating events
rickr (Fri, 20 Jul 2018 17:58:41 GMT):
Even on the loop that's tasking off events there's a check on the channels shutdown to not processes events.
oborovyk (Fri, 20 Jul 2018 18:43:31 GMT):
Well maybe it wouldn't but the possible thread leak is still a bad smell. And it would be really cool to add or remove listeners after the channel is initialized.
rickr (Fri, 20 Jul 2018 18:56:14 GMT):
There shouldn't be any thread leak either. The thread is interrupted and the the loop that's processing should break out on the shutdown set to true exiting the thread routine. The field that's holding the eventThread is also set to null so nothing should be referencing it either.
oborovyk (Fri, 20 Jul 2018 19:10:53 GMT):
Yes indeed. You're right.
rickr (Fri, 20 Jul 2018 19:11:43 GMT):
I just created class with a finalizer that printed out a message. Created an instance in that loop ... then intialized and shoutdown the channel .. The finalizer for that class printed out so it was GCed

one more question, regarding HSM.
In FABJ-308, it seems like the HSM for Java SDK has been developed already but in JavaSDK document it is written that current JavaSDK(v1.1 I presume) does not support HSM. which is correct?
or is it that HSM has been enabled but it is just not implemented in the current version? thanks!
rickr (Wed, 25 Jul 2018 23:41:07 GMT):
No. For signing and verifying the SDK is using Java JCA/JCE provided APIs ( _unless something has regressed_ ) An application would have to use a HSM Java security provider for HSM. The JSDK is not being regularly tested with any HSM so there are no guarantees it's working.

@rickr Is there anyway to get the genesis block through java sdk? Scenario: I have a channel with peer msp's configured and have started the channel. The peers are on different machines.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=oGL92Yv7o7TYyJzrN) @rickr Thanks. I did go through the code. There is one issue here - Channel newChannel = client.newChannel(name, anOrderer, channelConfiguration, client.getChannelConfigurationSignature(channelConfiguration, sampleOrg.getPeerAdmin())); creates a new channel. However in this case, assume that a channel has been created in one server. A peer on another server needs to join the channel (The new peer's MSP details have been added to the channel configuration). In the new peer, do I create a newChannel again and then join the peer to the new channel? This part is somewhat confusing.
rickr (Fri, 27 Jul 2018 11:05:00 GMT):
Don't create the channel .. and just join the peer. Seen End2endAndBackAgainIT when constructing the channel instead of adding the peer .. join it

akoenig (Tue, 31 Jul 2018 07:46:28 GMT):
@yulong12 I guess what you want to do is to call the method "move"? Because the invoke function sets inital values to "a" and "b"
akoenig (Tue, 31 Jul 2018 07:47:11 GMT):
the invoke function is just / should be just called once (After the intialiation of the chaincode)
akoenig (Tue, 31 Jul 2018 07:47:50 GMT):
you should take a look at the "E2E"-Test from the sdk
yulong12 (Tue, 31 Jul 2018 07:50:33 GMT):
no I call the method "invoke",the chaincode is in https://github.com/hyperledger/fabric-samples/blob/release-1.2/chaincode/chaincode_example02/go/chaincode_example02.go

it is different to Invoke
akoenig (Tue, 31 Jul 2018 08:06:26 GMT):
our problem is, that you just send the proposalrequest
but not the proposal it self
you have to send it like this:
Collection proposalResponses = channel.sendTransactionProposal(transactionProposalRequest);
CompletableFuture transactionEventCompletableFuture = channel
.sendTransaction(proposalResponses);

dave.enyeart (Tue, 31 Jul 2018 11:35:28 GMT):
@kelvinzhong you always need to set chaincode endorsement policy, whether using public data or private data or both. you only need to set the chaincode's collection configuration with distribution policy if you are using private data.
rickr (Tue, 31 Jul 2018 12:15:15 GMT):
@yulong12 IMO Take the time to walk through the integration tests they do a balance transfer and query results and much more. This should once you get started take half to a day tops I think .

rickr (Tue, 31 Jul 2018 12:22:50 GMT):
@kelvinzhong In general both are optional. You need a chaincode endorsement if you want to change the default. You need ChaincodeCollectionConfiguration if you intend to have private data defined.

Any suggestions on how to debug this certificate error attempting to use the Java SDK: Error handling message: event message validation failed: [failed deserializing event creator: [the supplied identity is not valid: x509: certificate signed by unknown authority]]? I've already added ca-cert.pem to the list of trusted certificates on my system.
I wonder if it's possible that there's a second relevant certificate that I don't know about.
rickr (Tue, 31 Jul 2018 16:21:00 GMT):
Double check that there is not an error prior to that. The logic is checking the response is verified but on some error the peer isn't signing
rickr (Tue, 31 Jul 2018 16:22:11 GMT):
Check the peer logs too

kelvinzhong (Wed, 01 Aug 2018 07:26:37 GMT):
@rickr @dave.enyeart thanks for the reply. And is that in V1.2 the transaction would automatically choose the endorsing peer base on the chaincode's collection configuration or endorsement policy?
kelvinzhong (Wed, 01 Aug 2018 07:33:46 GMT):
but it seems that it can't tell which collection would be used and choose the corresponding endorser...
rickr (Wed, 01 Aug 2018 11:46:14 GMT):
You either know _out of band_ what the endorsing policy is and choose peers that meet that or you can try service discovery see the latest 1.2 release notes
rickr (Wed, 01 Aug 2018 11:50:04 GMT):
Not sure I've answered your question: You either know _out of band_ what the endorsing policy is and choose peers that meet that or you can try service discovery see the latest 1.2 release notes. You combine the endorsing responses into a transaction that goes to the Orderer. From there each committing peer inspects that the endorsement policy was meet.

Hello, I have a chaincodeEventListener, which handles chaincodeEvents only when receiving from peer (and not EventHubs)
however, we seem to receive the same block twice, and therefore have a duplicate transaction handle.

kelvinzhong (Thu, 02 Aug 2018 03:19:01 GMT):
okay, I have go through the ServiceDiscoveryIT, but still have some confuses about the design of the collection.
for example: if there has a Collection a with authorize(A & B & C) and Collection b with authorize(C & D), theoretically we should not use both collection in one transaction right? otherwise the private data transaction would send to A、B、C and D.
and one more confuse, for the discovery service, if the endorsement policy is (A | B | C), and the collection authorize ( A & B), what endoser would the discovery service chose? if it is base on the endorsement policy, then the private data would expose to C

I just found that some note seems easy to be misunderstood in the docs http://hyperledger-fabric.readthedocs.io/en/latest/whatis.html
the section of "Pluggable Consensus", my colleague thought the orderer is the consensus node, and solo/kafka is consensus solution.
I think it is more like the pluggable ordering service consistency solution. and orderer is just a part of the consensus flow.
kelvinzhong (Thu, 02 Aug 2018 06:38:32 GMT):
@yacovm please correct me if i am wrong:grin:
yacovm (Thu, 02 Aug 2018 07:12:51 GMT):
long term the consensus algorithm should be pluggable too
yacovm (Thu, 02 Aug 2018 07:12:58 GMT):
right now you need to modify the code
kelvinzhong (Thu, 02 Aug 2018 08:31:40 GMT):
but it seems impossible to make the consensus algorithm pluggable unless change the transaction flow... to make the endorsement policy pluggable seems more reasonable for now...

@aatkddny If I recall correctly, you had a setup that explicitly defined peers, orderers but they switched to using service discovery with an update. You switched the roles back to just using explicitly defined chain again. Release notes has some info on service discovery.
aatkddny (Thu, 02 Aug 2018 14:08:39 GMT):
You don't recall correctly in this case.
It picked up the new service discovery role as a consequence of my not setting roles explicitly on the peer when I added it to the network configuration. It was defaulting to all roles, and failed when I upgraded 1.2 snapshot versions and picked up the new roles in the newer version.
It failed when I tried to do a channel loadFromNetworkConfig (or whatever the exact call is) inside the service discovery code. I wasn't trying to use discovery, I *just* wanted to connect to my channel so I could use the application built on top of the fabric. It went back to doing what it always did when I defined an EnumSet of peer roles that explicitly excluded the Service Discovery role and I haven't looked at it since - because it's all still working.
At the time I didn't care about service discovery - I just wanted my local fabric to work so I could do the demo I had scheduled. Silly me for upgrading versions...
Now I want to look at service discovery to see if it has any value for us. Hence I was wondering if anything had been changed that would fix whatever the original problem was before I go and change my code back to reconstitute a network with the discovery role on.
rickr (Thu, 02 Aug 2018 15:07:19 GMT):
I don't see anything other than you really should explicitly set the roles you want and when you did it worked.
If you want to move to doing service discovery as I said look at release notes

rickr (Mon, 06 Aug 2018 17:07:43 GMT):
If the peer (server) is shutdown the peer eventing service will continue to try and reconnect. If you then shutdown the channel there may be a gap in the code were it tries to reconnect but it's shutting down resulting in some things being not set. If this is it it's probably benign.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=4Gg9HRJ5WFGkfoFd2) @rickr There's clearly some miscommunication or misunderstanding here. And since I'm now back to looking at this perhaps you can help me figure out what the issue is.
I have a running fabric. It's all fine. Has been for a long old time now.
I want to now see if service discovery does anything for me.
*Assumption 1*
Having RTFM I don't see any changes to my compose files or anything else required to enable it.
*Assumption 2*
When I create my peers inside the channel reconstruct in the SDK I *think* I need to add the PeerRole.SERVICE_DISCOVERY to the EnumSet of PeerRoles to allow me to then use service discovery.
I *think* that's all I need to do differently from how it was (and is) working.
When I do this is when things go wrong. I haven't written a line of code to clone your ServiceDiscoveryIT functionality into my app yet.
I create my channels as normal.
I then try to install chaincode on the first channel I created as normal.
That's where things stop working.
The first sign things are different is this message `o.h.fabric.sdk.ServiceDiscovery : Channel xx-yy-channel doing discovery with peer: Peer peer0.xx.com url: grpcs://localhost:32001`
Followed by this one `o.h.fabric.sdk.ServiceDiscovery : Discover of chaincode names was empty.`
And then things go totally pear shaped. It starts throwing these out
`io.grpc.internal.ManagedChannelImpl : [io.grpc.internal.ManagedChannelImpl-129] Failed to resolve name. status=Status{code=UNAVAILABLE, description=Unable to resolve host peer0.xx.com, cause=java.net.UnknownHostException: peer0.xx.com: nodename nor servname provided, or not known`
I'm not really sure why setting that role as I have has caused this to go so badly wrong. I thought this was going to be simple.

For service discovery you should:
Only add peers you know .. preferably I would I think the ones in your organization. Add the all roles you want them to have and include SERVICE_DISCOVERY. Do the comparable if you are using a NetworkConfig.
For discovered peers/orderers the application can control the properties and roles they have by setting setSDPeerAddition, and setSDOrdererAddition.
For getting proposals use sendTransactionProposalToEndorsers
In a test environment where Peers and Orderers are just local you can set the system property org.hyperledger.fabric.sdk.test.endpoint_remap_discovery_host_name to 'localhost"
This is a test convenience to remap the hosts reported by service discovery to the localhost an not for example the docker internal host. This does mean your ports for fabric service need to be unique.

aatkddny (Tue, 07 Aug 2018 13:52:17 GMT):
I have full control over the entire network. I have all the definitions and all the crypto for all the orgs and all their peers. That's fairly straightforward.
I'm thinking that the problem is that I'm slavishly adding this role to all the peers when I'm installing chaincode and it's not dealing with that very graciously.
I expected the code to ignore that role until it was required and it appears it isn't. So in time-honored fashion I'll just forget about it and move on to the next thing on my list.
What I was *hoping* was that I could use SD to map my local network so I could build a NetworkConfig using it rather than the instantiation information I have inside my definition database.
This code runs inside my network creation server and is used to feed network config json to the client applications (aping the /connection_profile call inside the BMX api).
I need to keep my client application's code interoperable with BMX so I need to use the Channel.loadChannelFromConfig inside my client app.
I'll just forget about it for now until 1.2 goes GA there and I see what happens to the APIs. Thanks for the help - and I hope this means someone else with a standalone fabric doesn't go down the same rabbit hole.
rickr (Tue, 07 Aug 2018 14:08:20 GMT):
For me the *major* features service discovery provides is:
Dynamic discovery of other Peers and the Orderers in your network.
Dynamic discovery of what endorsements are need for proposals.

try a maven generate sources
mcoblenz (Tue, 07 Aug 2018 15:14:13 GMT):

mcoblenz (Tue, 07 Aug 2018 15:14:57 GMT):
but it's hard to tell which layer of things is broken. For example, 'mvn install' outputs:
mcoblenz (Tue, 07 Aug 2018 15:14:57 GMT):
[WARNING] Some problems were encountered while building the effective model for org.hyperledger.fabric-sdk-java:fabric-sdk-java:jar:1.3.0-SNAPSHOT

mcoblenz (Tue, 07 Aug 2018 15:15:30 GMT):
and 1.3.0-SNAPSHOT is odd because I'm on the release-1.2 branch. But it appears the version was changed before the tag was made…
mcoblenz (Tue, 07 Aug 2018 15:16:36 GMT):
But the 'maven install" command results in a bunch of warnings, and yet it reports 0 test failures.
mcoblenz (Tue, 07 Aug 2018 15:19:20 GMT):
But per the instructions, I am getting "BUILD SUCCESS", so I imagine I should ignore the console spew.
mcoblenz (Tue, 07 Aug 2018 15:32:20 GMT):
aha, I think a clean build and a generate-sources fixed it. Weird.

rickr (Wed, 08 Aug 2018 13:11:42 GMT):
Can you look at enabling trace documented in the readme also look at the peer logs. If that was received while getting endorsements most likely tfm05 chaincode isn't there on any peer. Make sure it is both installed AND instantiated on one peer.

FABJ-308 shows as closed
Ashish (Thu, 09 Aug 2018 08:45:04 GMT):
does this mean that we have an API which can let us keep the signing Private key in HSM and still get the transactions signed from java SDK?
Ashish (Thu, 09 Aug 2018 08:45:17 GMT):
without having to keep them in the java keystore locally ?
rickr (Thu, 09 Aug 2018 11:42:44 GMT):
No not exactly it was closed as a duplicate. There were patches made to make signing and verifying JCA/JCE complaint. But no regular testing so there is no guarantee it''s still working. HSM key management is provided by JCA/JCE via keystore so there's no need for the SDK to provide any API for that.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=B8t2dN8BNHr7zeJoX) @rickr Hey @rickr, after checking logs and other code details. I think it is related to docker compose file configuration in fabric network. Things like chainocde.address or externalendpointaddress may be one of the issue. Because if I remove the service discovery role from peer, then the invoke request is going through. Chaincode is installed on two nodes.
rickr (Thu, 09 Aug 2018 13:27:44 GMT):
If your working locally I think the ports used in the docker file should not be remapped .. look at the sdk it's docker compose for all peers are mapped direct
ports:
- 8051:8051
- 8053:8053

This makes sure its reporting the same port used internally and externally. There might be another maybe more elegant way todo that with something like CORE_PEER_GOSSIP_EXTERNALENDPOINT but I didn't have the time to go there :)

@Luke_Chen Take the time to get the End2endIT testcase in the sdk running in a debugger .. follow that code will show a lot. The eventhubs are now deprecated and you should use peers with eventing role. both monitored what blocks are actually commited and can complete the the future returned by the orderer to indicate the transactions is done on the peers being monitored

Hello! When invoking Node.js chaincode that returns an error, the Java SDK (1.2) throws this exception:
```
verify: Cannot retrieve peer identity from ProposalResponse. Error is: X.509 not found
org.hyperledger.fabric.sdk.exception.CryptoException: X.509 not found
at org.hyperledger.fabric.sdk.security.CryptoPrimitives.getX509Certificate(CryptoPrimitives.java:245)
at org.hyperledger.fabric.sdk.security.CryptoPrimitives.verify(CryptoPrimitives.java:319)
at org.hyperledger.fabric.sdk.ProposalResponse.verify(ProposalResponse.java:133)

at org.hyperledger.fabric.sdk.Channel.sendProposal(Channel.java:3515)
at org.hyperledger.fabric.sdk.Channel.sendTransactionProposal(Channel.java:3398)
```
In the `org.hyperledger.fabric.sdk.ProposalResponse#verify` method, it seems that `proposalResponse.getEndorsement()` returns an empty `endorser` attribute. The empty `endorser` is passed to the `crypto.verify` method:
```
this.isVerified = crypto.verify(endorser.getIdBytes().toByteArray(), config.getSignatureAlgorithm(),
sig.toByteArray(), plainText.toByteArray()
);
```
The `crypto.verify` method is throwing a `CryptoException` because it cannot find a SecurityProvider that can parse the empty endorser cert PEM.
The chaincode in question simply does this:
```
this.shim.error('Trade Termsheet already created. Use modify instead.');
```
I'd assume that an invalid chaincode proposal response wouldn't have an endorser so the `ProposalResponse#verify` should just bail at this point (instead of setting the `this.isVerified`):
```
public boolean verify(CryptoSuite crypto) {
if (isVerified()) { // check if this proposalResponse was already verified by client code
return isVerified();
}
if (isInvalid()) {
this.isVerified = false;
}
```

rickr (Fri, 10 Aug 2018 13:02:34 GMT):
IMO the easiest solution is to make sure docker file is not doing port remapping See the sdk example all ports external and internal are the same. There are environment settings that tell peer to listen to those ports. The same is done for the orderer

@jalmeida Too many possibilities even with that stacktrace. I think from that it got to the Orderer so you should probably enable the Orderer for debug output and begin there. Most likely if you can't figure it out the #fabric-orderer channel for asking questions is your best bet.

Hello! I'm trying to create channel using "HFClient.newChannel" and NetworkConfig. The problem is that newChannel required Orderer as parametr, but NetworkConfig keep it in private fields with no access. The same problem with channel.joinPeer, which require peer

yacovm (Mon, 13 Aug 2018 09:49:33 GMT):
yes, what is it?
yacovm (Mon, 13 Aug 2018 09:50:07 GMT):
@aatkddny what do you mean "until it's more mature" ?
yacovm (Mon, 13 Aug 2018 09:50:14 GMT):
SD is mature :(
yacovm (Mon, 13 Aug 2018 09:50:24 GMT):
the golang SDK uses it quite well
ShobhitSrivastava (Mon, 13 Aug 2018 09:58:38 GMT):
@yacovm. This is the one I am referring to. I have one docker compose file. Code is working fine when I am not using Service Discovery option for peer instead using 1.1 fashion.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=mvMiQPzAL6dS3fcLv) @yacovm Guess it was for java not for go sdk
rickr (Mon, 13 Aug 2018 10:13:56 GMT):
From where your running the client is your peer at `peer0.exporter.test` ? can you telnet to it ?

yes peer0.exporter.test is a peer. And it is reachable if I remove SD from java sdk

rickr (Mon, 13 Aug 2018 10:40:51 GMT):
removing SD from java sdk has now affect on whether from your client using tcpip it rsolves the hostname peer0.exporter.test
rickr (Mon, 13 Aug 2018 10:40:51 GMT):
removing SD from java sdk has no affect on whether from your client using tcpip it rsolves the hostname peer0.exporter.test
ShobhitSrivastava (Mon, 13 Aug 2018 10:43:54 GMT):
Correct, but thing are working absolutely fine if i remove SD from peerOption.

rickr (Mon, 13 Aug 2018 10:55:40 GMT):
to use test remapping that your ports in the dockercompose will need to be the same for both inside and outside of docker I.e the number on both sides of the colon need to be the same

rickr (Mon, 13 Aug 2018 10:59:50 GMT):
So you didn't follow it for testing to docker set the java system property org.hyperledger.fabric.sdk.test.endpoint_remap_discovery_host_name to 'localhost"
rickr (Mon, 13 Aug 2018 11:00:31 GMT):
AND as stated in docker compose you'll need to make sure your ports are NOT being remapped
ShobhitSrivastava (Mon, 13 Aug 2018 11:03:03 GMT):
hey @rickr . The only issue in that is my fabric network is on a standalone linux server. Putting local host wont solve it
rickr (Mon, 13 Aug 2018 11:04:01 GMT):
its on another machine ?
ShobhitSrivastava (Mon, 13 Aug 2018 11:04:06 GMT):
yes
rickr (Mon, 13 Aug 2018 11:04:17 GMT):
so what's thats machines hostname ?
ShobhitSrivastava (Mon, 13 Aug 2018 11:05:11 GMT):
its inside closed network. So hostname is not there instead reachable by IP
rickr (Mon, 13 Aug 2018 11:05:59 GMT):
when you create the peer manually what url do you give ?
ShobhitSrivastava (Mon, 13 Aug 2018 11:08:33 GMT):
From SDK======>
private static final String PEER1_NAME = "peer0.exporter.test";
private static final String PEER2_ADDRESS = "grpc://10.64.217.120:7051";
Peer peer2 = hfclient.newPeer(PEER2_NAME, PEER2_ADDRESS);
testChannel.addPeer(peer2);
rickr (Mon, 13 Aug 2018 11:08:54 GMT):
are ALL your peers and orderers on that system ?
ShobhitSrivastava (Mon, 13 Aug 2018 11:09:00 GMT):
yes
rickr (Mon, 13 Aug 2018 11:09:45 GMT):
on then set that system property to 10.64.217.120
ShobhitSrivastava (Mon, 13 Aug 2018 11:10:17 GMT):
is it any java variable?
rickr (Mon, 13 Aug 2018 11:10:53 GMT):
google java system propertis
ShobhitSrivastava (Mon, 13 Aug 2018 11:11:28 GMT):
okay..thanks for this. I will make the changes and get back to you
rickr (Mon, 13 Aug 2018 11:11:39 GMT):
AND it won't work if in your dockercompose your remapping ports
rickr (Mon, 13 Aug 2018 11:13:05 GMT):
@yacovm is there another way for SD to report the external host clients should connect to for service discovery ? ^^^
yacovm (Mon, 13 Aug 2018 11:13:41 GMT):
what do you mean exactly?
yacovm (Mon, 13 Aug 2018 11:13:52 GMT):
we only report the external endpoints
yacovm (Mon, 13 Aug 2018 11:14:00 GMT):
what is the use case?
rickr (Mon, 13 Aug 2018 11:15:01 GMT):
read the above
yacovm (Mon, 13 Aug 2018 11:15:14 GMT):
no TLDR? :(
rickr (Mon, 13 Aug 2018 11:16:14 GMT):
@ShobhitSrivastava explain your network layout and use case
ShobhitSrivastava (Mon, 13 Aug 2018 11:18:44 GMT):
Okay. I have a running fabric network which is working if I remove SD option from adding to peer. When I add peerOPtion as ServiceDiscovery, it does not work. All the peers and orderer are on one machine
yacovm (Mon, 13 Aug 2018 11:18:57 GMT):
do you have anchor peers?
yacovm (Mon, 13 Aug 2018 11:19:01 GMT):
do the peers see each other?
yacovm (Mon, 13 Aug 2018 11:19:10 GMT):
did you try to use https://hyperledger-fabric.readthedocs.io/en/latest/discovery-cli.html to see if the peers know each other?
ShobhitSrivastava (Mon, 13 Aug 2018 11:20:18 GMT):
yes, the peers in their Org are anchor one. No I have not used Discover command
rickr (Mon, 13 Aug 2018 11:21:24 GMT):
Is the sdk client on the at same system ?
ShobhitSrivastava (Mon, 13 Aug 2018 11:22:07 GMT):
no, it is outside the system. But it is reachable.
rickr (Mon, 13 Aug 2018 11:22:37 GMT):
but not what SD is reporting is reachable
ShobhitSrivastava (Mon, 13 Aug 2018 11:23:14 GMT):
yes. SD is not
yacovm (Mon, 13 Aug 2018 11:23:25 GMT):
please use the `discover peers` command from the manual I linked
yacovm (Mon, 13 Aug 2018 11:23:30 GMT):
and report your findings here
yacovm (Mon, 13 Aug 2018 11:23:48 GMT):
if the peers don't see each other, the discovery won't work for policies with an AND
ShobhitSrivastava (Mon, 13 Aug 2018 11:24:24 GMT):
Yeah I am doing that. But where will I have to run it. Mean in whose bash?
rickr (Mon, 13 Aug 2018 11:25:04 GMT):
it won't matter it's going to report addresses that are not reachable
rickr (Mon, 13 Aug 2018 11:26:44 GMT):
It will report hosts with peer0.exporter.test` just like the Java SDK gets but that's not reachable from your client as you stated
ShobhitSrivastava (Mon, 13 Aug 2018 11:27:44 GMT):
@rickr . Look if i fire it in like outside any bash. I am getting no command found
ShobhitSrivastava (Mon, 13 Aug 2018 11:28:21 GMT):
So it needs to be run somewhere inside any bash or is there any specific tool is required?
rickr (Mon, 13 Aug 2018 11:29:11 GMT):
@yacovm ^^
yacovm (Mon, 13 Aug 2018 11:29:47 GMT):
oh
yacovm (Mon, 13 Aug 2018 11:29:50 GMT):
you need to download it
yacovm (Mon, 13 Aug 2018 11:29:53 GMT):
https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/
yacovm (Mon, 13 Aug 2018 11:30:02 GMT):
we didn't put it as part of the CLI container in v1.2 :(
ShobhitSrivastava (Mon, 13 Aug 2018 11:30:10 GMT):
yeah okay
rickr (Mon, 13 Aug 2018 11:30:55 GMT):
run it from where you run the JSDK
rickr (Mon, 13 Aug 2018 11:31:16 GMT):
As stated I don't think this exercise is going to show anything new
ShobhitSrivastava (Mon, 13 Aug 2018 11:32:00 GMT):
@yacovm which link is needed to open on this repo? There are many link
ShobhitSrivastava (Mon, 13 Aug 2018 11:32:42 GMT):
@rick. I need to know how I can run dicover peer command on JSDK
ShobhitSrivastava (Mon, 13 Aug 2018 11:33:29 GMT):
sdk is on my local windows machine, dont think it has discover command
rickr (Mon, 13 Aug 2018 11:37:55 GMT):
that discover command has nothing to do with the JSDK
rickr (Mon, 13 Aug 2018 11:38:54 GMT):
It's going to report the same peer endpoint names as the JSDK but as you have seen already those are NOT reachable from your windows machine
ShobhitSrivastava (Mon, 13 Aug 2018 11:40:13 GMT):
Yes
ShobhitSrivastava (Mon, 13 Aug 2018 11:40:45 GMT):
I will set the java system property. And see after wards
yacovm (Mon, 13 Aug 2018 11:58:44 GMT):
@ShobhitSrivastava pick your architecture and pick v1.2
yacovm (Mon, 13 Aug 2018 11:59:03 GMT):
for example https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.2.0/
ShobhitSrivastava (Mon, 13 Aug 2018 12:09:16 GMT):
okay

hey @rickr . I am debugging the code, even after explicitly specifying protocol as grpc it is still taking grpcs(in url in Peer.java) which is causing this unavailable hostname issue

rickr (Mon, 13 Aug 2018 12:48:28 GMT):
@ShobhitSrivastava no that will not cause a unavailable hostname
ShobhitSrivastava (Mon, 13 Aug 2018 12:50:41 GMT):
I am still not sure where is this "grpc" is getting changed to "grpcs"
rickr (Mon, 13 Aug 2018 12:57:58 GMT):
Study ServiceDiscoveryIT.java
ShobhitSrivastava (Mon, 13 Aug 2018 13:02:19 GMT):
yup
leusgrif (Mon, 13 Aug 2018 13:28:40 GMT):
@rickr thx for your answer! The source you pointed to shows how to get Properties of orderer or peer. But "HFClient.newChannel" require instance of Orderer. I can't get one from NetworkConfig cause it's private. And i cant construct one using "HFClient.newOrderer(name, grpscURL, properties)" cause i can't get URL from NetworkConfig.
rickr (Mon, 13 Aug 2018 13:44:51 GMT):
And this won't work for you ?

leusgrif (Mon, 13 Aug 2018 14:02:38 GMT):
@rickr Unfortunately, no it doesn't. If i understand sdk correctly "loadChannel" supposed that the channel is already created.
leusgrif (Mon, 13 Aug 2018 14:03:30 GMT):
i want to have endpoint which allow me to create channel providing path to channel.tx in existing fabric network
rickr (Mon, 13 Aug 2018 14:03:37 GMT):
Network config does not support creating channels
leusgrif (Mon, 13 Aug 2018 14:04:20 GMT):
It's really sad. Why is it so?
leusgrif (Mon, 13 Aug 2018 14:04:50 GMT):
I suppose it doesn't support joining peers as well?
rickr (Mon, 13 Aug 2018 14:11:50 GMT):
exactly Those really are rare done by an Admin. Networkconfig purpose was to make the channel on the sdk quick to `reconstruct` an existing channel. More than like and Admin or some back end code would be created for doing Channel creation and peer joining And the networkconfig created and distributed to end user for deploying, invoking querying chaincode.
That said there is a _possible_ HACK not tried but would do what you want I think. Load the channel as I showed. You don't have to initialize it. From there you can get the peers/orderers and urls. Then shut it down.
leusgrif (Mon, 13 Aug 2018 14:29:22 GMT):
@rickr This hack was my backup plan). I will try it but i still don't understand why nodes url is private in networkConfig. Thanks for your answers!
kelvinzhong (Tue, 14 Aug 2018 07:47:35 GMT):

what might cost this?
kelvinzhong (Tue, 14 Aug 2018 08:11:56 GMT):
while using the discovery service, if the peer did not set the properties, it would cause the null-pointer exception in
if ((properties == null) || (isNullOrEmpty(properties.getProperty("clientCertFile")) &&
isNullOrEmpty(properties.getProperty("clientCertBytes")))) {
TLSCertificateBuilder tlsCertificateBuilder = new TLSCertificateBuilder();
TLSCertificateKeyPair tlsCertificateKeyPair = tlsCertificateBuilder.clientCert();
peer.setTLSCertificateKeyPair(tlsCertificateKeyPair);
}
if the properties is null, then peer would call the setTLSCertificateKeyPair, and here would cause the null-pointer exception as it set the properties to the peer properties which is null
kelvinzhong (Tue, 14 Aug 2018 08:12:32 GMT):
which is a bug here
rickr (Tue, 14 Aug 2018 10:57:31 GMT):
can you give NPE stack trace
rickr (Tue, 14 Aug 2018 10:57:31 GMT):
can you give NPE stack trace and try using :

rickr (Tue, 14 Aug 2018 10:58:32 GMT):
`Unable to resolve host peer0.platform.com,` can you resolve that from your client ?
kelvinzhong (Tue, 14 Aug 2018 11:15:16 GMT):
ok I can try to reproduce the NPE now
kelvinzhong (Tue, 14 Aug 2018 11:15:40 GMT):
but i have no idea what might cause the "Unable to resolve host peer0.platform.com"

@rickr https://ctrlv.it/id/142863/3521491506
kelvinzhong (Tue, 14 Aug 2018 11:21:27 GMT):
i have install the chaincode to each ogrs, and instantiate in one org, but only this org have create the chaincode container, and the discovery service could not find the others, then throw a warning "Unable to resolve host peer0.platform.com"
rickr (Tue, 14 Aug 2018 12:22:44 GMT):
@kelvinzhong Can you open a JIRA bug put that stack trace in there. It trying to automaically generate a certificate not sure why its null.
rickr (Tue, 14 Aug 2018 12:24:48 GMT):
include the output of `java -XshowSettings:properties -version`
rickr (Tue, 14 Aug 2018 12:31:35 GMT):
The work around to avoid that is to set properties for the peer to create tls certs add `clientKeyBytes` and `clientCertBytes`
kelvinzhong (Tue, 14 Aug 2018 12:38:40 GMT):
I think the bug is obviously....

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=qNpXwEiw7wRz2Pcu5) @yacovm then how about "until it doesn't break my working network with some ugly grpc error that i have neither the time nor the inclination to debug when i turn it on in the peer".
my channels are coming from a network config file so i know what my peers are.
until i have a use case for endorsement that i don't know which peers are required - and i write the policies, so that's not happening - i'm leaving it well alone. i have enough other stuff to keep me busy.

@rickr what could cause this... I can't find any config is different from the ServiceDiscoveryIT...
kelvinzhong (Wed, 15 Aug 2018 06:44:57 GMT):

@yacovm Is there anyway this can be done without doing this ? What happens when service discovery is behind a proxy ? Something needs to be able report the external endpoints and not the internal ones I think there is an you provide some details

Not sure what is the problem?
yacovm (Wed, 15 Aug 2018 11:04:04 GMT):
Can you clearly state the issue? I'm on mobile
yacovm (Wed, 15 Aug 2018 11:04:50 GMT):
Why are you not just generating localhost certificates?
rickr (Wed, 15 Aug 2018 11:09:59 GMT):
I don't know how to make it more simple. Your hyperledger systems peers orders is behind a proxy their internal addresses are not accessible from the clients but only through the external proxy through external endpoints . How would you get serviced discovery to report those external endpoints and not the internal ones
rickr (Wed, 15 Aug 2018 11:09:59 GMT):

Just use the external_endpoint cobfiguration parameter
yacovm (Wed, 15 Aug 2018 11:14:49 GMT):
And assign it to be the proxy endpoont
rickr (Wed, 15 Aug 2018 11:16:11 GMT):
Not urgent .. so when you get off your cellphone :) can you provide the exact ones ? Also does that work for the Orderer too ?
yacovm (Wed, 15 Aug 2018 11:17:03 GMT):
CORE_PEER_GOSSIP_EXTERNAL_ENDPOINT
yacovm (Wed, 15 Aug 2018 11:17:18 GMT):
In the docker composr file
kelvinzhong (Wed, 15 Aug 2018 11:22:06 GMT):
so i just need to config the CORE_PEER_GOSSIP_EXTERNAL_ENDPOINT to the actual peer url or set the org.hyperledger.fabric.sdk.test.endpoint_remap_discovery_host_name for test, right?
kelvinzhong (Wed, 15 Aug 2018 11:23:48 GMT):
and one more question... why discovery service can only find the peers in the same MSP? what about the peer from other MSP which also join in the same channel?
rickr (Wed, 15 Aug 2018 11:24:07 GMT):
don't do both
rickr (Wed, 15 Aug 2018 11:25:25 GMT):
the second issue I think _maybe_ due to gossip not set up right
kelvinzhong (Wed, 15 Aug 2018 11:26:40 GMT):
got it
kelvinzhong (Wed, 15 Aug 2018 11:27:28 GMT):
what is this config CORE_PEER_GOSSIP_BOOTSTRAP using for?
kelvinzhong (Wed, 15 Aug 2018 11:28:02 GMT):
i set this CORE_PEER_GOSSIP_BOOTSTRAP as the anchor peer in each MSP
kelvinzhong (Wed, 15 Aug 2018 11:28:20 GMT):
should I set it to the same peer?
yacovm (Wed, 15 Aug 2018 11:28:35 GMT):
The discovery returns all the peers the peer you ask, know about
yacovm (Wed, 15 Aug 2018 11:28:48 GMT):
To know other msps you need anchor peers
kelvinzhong (Wed, 15 Aug 2018 11:29:57 GMT):
indeed I use the anchor peer to do the discovery, but still only find the peer in the same org
kelvinzhong (Wed, 15 Aug 2018 11:30:24 GMT):
also i have successfully install and instantiate chaincode in all peers
kelvinzhong (Wed, 15 Aug 2018 11:48:02 GMT):
@rickr is there any chance to add a test for multiple MSP discovery....
kelvinzhong (Wed, 15 Aug 2018 11:49:05 GMT):
I have check all the config and can't find why the discovery can only find the orderer and the peer in the same MSP
yacovm (Wed, 15 Aug 2018 11:50:57 GMT):
Seems like the anchor peers are not properly used
kelvinzhong (Wed, 15 Aug 2018 11:53:46 GMT):
I have set the configtx.yaml AnchorPeers HOST and PORT same as the CORE_PEER_GOSSIP_EXTERNALENDPOINT,what else need to be config to make the anchor peer work?
kelvinzhong (Wed, 15 Aug 2018 11:53:46 GMT):
I have set the configtx.yaml AnchorPeers HOST and PORT same as the CORE_PEER_GOSSIP_EXTERNALENDPOINT,what else needed to be config to make the anchor peer work?
yacovm (Wed, 15 Aug 2018 11:55:38 GMT):
Nooo
yacovm (Wed, 15 Aug 2018 11:55:53 GMT):
You need to update them after the genesis block
yacovm (Wed, 15 Aug 2018 11:55:58 GMT):
As a confog update
kelvinzhong (Wed, 15 Aug 2018 11:57:22 GMT):
really?!
kelvinzhong (Wed, 15 Aug 2018 12:00:48 GMT):
the config of the anchor peer wasn't already initialize while creating a channel?
yacovm (Wed, 15 Aug 2018 12:02:20 GMT):
Nooo
yacovm (Wed, 15 Aug 2018 12:02:29 GMT):
You need to do it after
yacovm (Wed, 15 Aug 2018 12:02:34 GMT):
For each org
yacovm (Wed, 15 Aug 2018 12:02:46 GMT):
@jyellick is that correct?
kelvinzhong (Wed, 15 Aug 2018 12:30:02 GMT):
sounds not true...if in that case what is the point to set the anchor peer in the config.yaml....
albert.lacambra (Wed, 15 Aug 2018 12:58:03 GMT):
hi
some idea what this message exactly means?
ejecting broadcast of config message from 172.18.90.174:49173 because of error: error authorizing update: error validating ReadSet: readset expected key [Group] /Channel/Application at version 0, but got version 1
jyellick (Wed, 15 Aug 2018 17:43:15 GMT):
@yacovm Correct, anchor peers are not set during channel creation time (even if they are present in `configtx.yaml`, they must be updated after.
jyellick (Wed, 15 Aug 2018 17:43:35 GMT):
(Usually, this is done per org, submitted by the respective admins)
yacovm (Wed, 15 Aug 2018 17:46:34 GMT):
@kelvinzhong see? ^ I am correct!
yacovm (Wed, 15 Aug 2018 17:46:44 GMT):
thanks @jyellick
jyellick (Wed, 15 Aug 2018 17:55:22 GMT):
There are two reasons why anchor peers are not set during channel creation time:
1. A peer cannot join a channel until after the channel is created, therefore, specifying a peer as an anchor peer during channel creation would imply a period of misconfiguration, while the network believes a peer is an anchor peer for a channel, but it is not yet joined.
2. Channel creation is usually done only by a single org admin. That admin does not have authority to set the anchor peer for the other organizations, only for his own. Therefore, without collecting signatures from the other admins, the creation request would fail.
kelvinzhong (Thu, 16 Aug 2018 01:50:44 GMT):
@yacovm okay, thanks anyway :smile:
kelvinzhong (Thu, 16 Aug 2018 01:52:53 GMT):
so that is the case, do we have any tutorial relate to config the anchor peer? and what does the anchor peer used for in the config.yaml?
kelvinzhong (Thu, 16 Aug 2018 01:52:53 GMT):
i found the configtxgen has a command for anchor peer update, my mistake:grin:

is this one? Channel.queryBlockchainInfo()

GetChainInfo which is from the go client which I'm not as familar with but I think that's equivalent to queryBlockchainInfo

Not seen that before. Is that reoccurring ?
aatkddny (Fri, 17 Aug 2018 16:02:36 GMT):
One time and didn't affect operation. A few seconds of google make it appear as if it was a channel that was discarded without being shut down and subsequently GC'd. That makes sense given my program flow - I'd just never seen it before.
rickr (Fri, 17 Aug 2018 16:04:46 GMT):
So other than the ugly stack trace you suffered no ill harm :)
asaningmaxchain123 (Fri, 17 Aug 2018 16:06:30 GMT):
@rickr the java sdk can parse the chaincode endorsement policy ,and than send the tx to `possible peer` not the `all peer`?
aatkddny (Fri, 17 Aug 2018 16:10:24 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=5gCcA28bLjWqh2fJt) @rickr Well I did spend a few minutes wondering what I'd just broken. I'd been editing my peer create method when it popped up. But no, no ill effects other than a polluted log.
rickr (Fri, 17 Aug 2018 16:13:58 GMT):
@asaningmaxchain123 No the SDK may not know the endorsement policy without service discovery. Could be some other organization (another client) that installed and instantiated the CC with endorsement policy. Your client sdk wouldn't know it unless communicated out of band or using service discovery
asaningmaxchain123 (Fri, 17 Aug 2018 16:16:00 GMT):
so, i should start the service discovery in my app?
asaningmaxchain123 (Fri, 17 Aug 2018 16:18:31 GMT):
if i set the `service discovery`. that means the app would keep heart beat with the peer to test it's alive?
rickr (Fri, 17 Aug 2018 16:18:42 GMT):
Ideally but I need to get something fixed first :blush:

@rickr sorry, but do you know why most of the classes in the sdk are package private?
rickr (Tue, 21 Aug 2018 09:43:15 GMT):
What's your specific use case that you can't do with publicly available classes and methods ?
akoenig (Tue, 21 Aug 2018 10:03:35 GMT):
for example the EndorserClient, or the OrdererClient are package private. They say "example code", but to use the same methods like those clients i need to be in same package again
rickr (Tue, 21 Aug 2018 10:05:23 GMT):
As an application using the sdk I don't see any need to access those.
akoenig (Tue, 21 Aug 2018 10:06:54 GMT):
or the TransactionOptions -> public class but all properties are private. I just wanted to know if this is written so on prupose or not?
akoenig (Tue, 21 Aug 2018 10:10:55 GMT):
wrote you why we need this in sperate chat ;)
rickr (Tue, 21 Aug 2018 10:11:17 GMT):
The classes and methods that are public _should_ be adequate to address the use cases we see SDK should address. If you have a uses cases as an application using the SDK that's not meet open a JIRA
akoenig (Tue, 21 Aug 2018 10:13:34 GMT):
mhm, okay I see. I will discuss our usecase and will create a JIRA ticket. Maybe we can contribute to this or something

The SDK should purpose is mostly to deploying and executing chiancode and doing some queries. The parts of service discovery that helped facilitate that are used.

@Smit95shah you might better look into the peer's log trace

Hi @kelvinzhong Thanks for replying. May I know how can check the trace.
akoenig (Wed, 22 Aug 2018 06:45:52 GMT):
@Smit95shah you can look inside the docker-image of the peer and look at the console. Or if you have kitmatic for docker you can have a look their. Our exception is maybe a hint to wrong configuration of the peer? Name/Port or something else...
kelvinzhong (Wed, 22 Aug 2018 07:02:20 GMT):
@Smit95shah look into the peer's docker logs
kelvinzhong (Wed, 22 Aug 2018 07:02:43 GMT):
@rickr @yacovm I got a complex scenario, please help me to understand
1. can a chaincode call the function from the other chaincode which in the same channel?
2. assume 1 is yes, the discovery service could choose the peer base on endorsement policy or Collection for private data, what if a chaincode required for peerMSP A and B, and call the other chaincode which required for peerMSP A and C, then what would happened?
would it send the proposal only to A and B at first then redirect to the second chaincode only for A and C?
yacovm (Wed, 22 Aug 2018 07:19:03 GMT):
1. Yes
yacovm (Wed, 22 Aug 2018 07:19:36 GMT):
2. I have support for cc2cc queries
yacovm (Wed, 22 Aug 2018 07:21:27 GMT):
I = the peer
yacovm (Wed, 22 Aug 2018 07:21:45 GMT):
You give the peer both chaincodes and it computes it based on the combined policies
yacovm (Wed, 22 Aug 2018 07:22:05 GMT):
Not sure if Rick implemented the client side support yet though
Smit95shah (Wed, 22 Aug 2018 07:22:42 GMT):
Hi @kelvinzhong @akoenig I dont see any movements in the Kitmatic logs for that peer0. I believe, that I am unable to connect correctly?
akoenig (Wed, 22 Aug 2018 07:28:48 GMT):
Mhm, thats why I was saying the second part: "your exception is maybe a hint to wrong configuration of the peer? Name/Port or something else..."
akoenig (Wed, 22 Aug 2018 07:29:28 GMT):
would recomend to check again, which peer you are speeking, too and if your mapping between the jdk and docker-image is right (port, host name etc.)
Smit95shah (Wed, 22 Aug 2018 07:57:06 GMT):
Thanks.
Smit95shah (Wed, 22 Aug 2018 07:57:18 GMT):

Smit95shah (Wed, 22 Aug 2018 07:57:36 GMT):
is there a place where i can change http2 to http1?
kelvinzhong (Wed, 22 Aug 2018 08:07:26 GMT):
@yacovm thanks for the answer, but what if the private data required A and B can access only and the other chaincode required A and C only? for what I understand is that the proposal will send to the A、B、C at the same time or just send to A?
kelvinzhong (Wed, 22 Aug 2018 08:23:38 GMT):
one more thing...is cc2cc support query only?
yacovm (Wed, 22 Aug 2018 08:23:39 GMT):
you can also add a collection in the discovery request
yacovm (Wed, 22 Aug 2018 08:23:47 GMT):
and the discovery service would take that into account
yacovm (Wed, 22 Aug 2018 08:23:53 GMT):
and filter out peers not in the collection
kelvinzhong (Wed, 22 Aug 2018 08:24:29 GMT):

rickr (Wed, 22 Aug 2018 10:40:08 GMT):
You can get from the config block. But the SDK for that doesn't _interpret_ it for you. You'll need to parse it on your own.

Hi there, Does anyone knows how to use fabric idemix in Java SDK
rickr (Wed, 22 Aug 2018 12:28:36 GMT):
Should be integration code showing idemix being used *when it's released*. Almost no difference at all between x509 cert and id
rickr (Wed, 22 Aug 2018 12:28:36 GMT):
Should be integration code showing idemix being used *when it's released*. The short of it is: almost no difference at all between x509 cert and idemix except that you'll need to have a separate idemix user context that has an enrollment gotten with the CA that is an idemix enrollment instead of x509. The idemix user context is limited to just invoking chaincode.

Hello, is there a limit as to how big the outgoing transaction can be?
I'm trying to modify my chaincode to accept an array of JSON objects, instead of just one, but the transaction proposal fails with the following error on the peer:
`2018-08-23 12:43:12.992 UTC [chaincode] processStream -> ERRO 0b6 Error handling chaincode support stream: rpc error: code = Canceled desc = context canceled`

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=CCfopfrxBZ7Fv3zTS) If you are using kafka, I understood it to be the maximum size of the message allowable to kafka minus some overhead.
There's a formula for it, but I forgot it because my messages weren't that large. The property (again iirc) is KAFKA_MESSAGE_MAX_BYTES=103809024 in the kafka config yaml.
If you are using a local orderer it's set in a config file somewhere that requires a recompile, and it isn't very big. Ask me how I know...
There's also a further limit in config.tx `AbsoluteMaxBytes`

Ok I not sure I'm capturing your first issue but I modified the End2endIT to give a different name that was installed for instantiate and got back :
```
Not enough endorsers for instantiate :0endorser failed with cannot get package for chaincode (foome_rick:1), on peerPeer peer0.org1.example.com url: grpcs://localhost:7051
Not enough endorsers for instantiate :0endorser failed with cannot get package for chaincode (foome_rick:1), on peerPeer peer1.org1.example.com url: grpcs://localhost:7056
```
It even gave back a reasonable message that the wrong chaincode name I tried to invoke.
I also then changed the regular invoke (move) after the instantiate with a bad name and it too came back with a reasonable error

@albert.lacambra I think I may have reproduced it. If I just do a docker stop/start on the peer I see the results I showed. The connect/reconnect takes some time so the attempts are reasonable. When it reconnects it ask for the block it last seen on the channel On a docker stop/start the ledger channel is still there and it gets the block and all is _happy path from there_.
Now if I actually bring it all down destroy the containers and bring it back up the peereventing services ask for the block it last seen on the channel but the channel is no longer there . So you have
`2018-08-25 21:24:27,610 grpc-default-executor-14 TRACE PeerEventServiceClient:196 - DeliverResponse channel foo peer peer1.org1.example.com resp status value:404 status NOT_FOUND, typecase STATUS`
This causes a lot of failures fast.
This I think is not as typical as just not being able to connect. I have to figure out to best handle.
Any chance this seems what you're doing @albert.lacambra ?

is it possible to turn off these logs without decreasing overall debug level from debug to info?
rickr (Tue, 28 Aug 2018 10:33:24 GMT):
The default is INFO

@rickr i do found some warning in peers

kelvinzhong (Tue, 28 Aug 2018 10:46:32 GMT):
but what should i do? or what can sdk improve?
Krono (Tue, 28 Aug 2018 10:46:33 GMT):
Hi. I'm a pretty new to this, so I hope I'm bringing this to the right place..
We tried to reference the Java SDK as dependency in an android studio project.
However the compiler complains about the javax.json dependency of the sdk containing an illegal class file.
And now I wonder if android support is actually in the scope of this sdk?
kelvinzhong (Tue, 28 Aug 2018 10:47:23 GMT):
set keep alive to peers?
rickr (Tue, 28 Aug 2018 10:47:24 GMT):
Don't test or try on android
rickr (Tue, 28 Aug 2018 10:48:11 GMT):
@kelvinzhong if you're running through a proxy that might help
Krono (Tue, 28 Aug 2018 10:48:30 GMT):
Well, thats unambiguous. Thanks ^^
kelvinzhong (Tue, 28 Aug 2018 10:49:26 GMT):
so this would happen because i was connected by ip directly?
kelvinzhong (Tue, 28 Aug 2018 10:51:04 GMT):
would it help if i set the keep alive properties to the peers?
kelvinzhong (Tue, 28 Aug 2018 10:55:40 GMT):
but the peer is discovered by discovery service...i could not set the keep alive properties to peers...
rickr (Tue, 28 Aug 2018 11:07:16 GMT):
https://github.com/hyperledger/fabric-sdk-java/blob/master/docs/release_v1.2.0_notes.md#fab-8805-jsdk-service-discovery
kelvinzhong (Tue, 28 Aug 2018 11:17:28 GMT):
the discovery service is fine, what i try to say is peer has disconnect the client, but sdk didn't try to reconnect, therefor client could not receive the peer event of the transaction
kelvinzhong (Tue, 28 Aug 2018 11:17:28 GMT):
the discovery service is fine, what i'm trying to say is the peer has disconnect the client, but sdk didn't try to reconnect, therefor client could not receive the peer event of the transaction
rickr (Tue, 28 Aug 2018 11:20:47 GMT):
Where do you know the sdk didn't try to connect ? And you asked about setting properties on the peers discovered by service discovery
kelvinzhong (Tue, 28 Aug 2018 11:59:44 GMT):
i have open the trace log in sdk, i haven't seen the reconnect log in sdk, but i found the disconnect log in peer, so i assume the sdk didn't trigger the reconnect
kelvinzhong (Tue, 28 Aug 2018 12:00:27 GMT):
i would try to reproduce this tomorrow, and look into more detail
rickr (Tue, 28 Aug 2018 14:10:47 GMT):
If you really are connecting through a proxy I would first try and get the keep alive on the connections done.
yacovm (Tue, 28 Aug 2018 23:09:47 GMT):
@kelvinzhong if you have peer communication issues you should ask in #fabric-gossip , just saying :)
rickr (Wed, 29 Aug 2018 01:26:46 GMT):
If I think it has anything to do with gossip have no worries I'll send him there, _just saying_ :)

Hi all
Who knows, what this command `fabric-ca-client getcacert` actually do?
Not really clear from the documentation
rickr (Wed, 29 Aug 2018 14:31:26 GMT):
https://github.com/hyperledger/fabric-sdk-java/blob/master/src/main/java/org/hyperledger/fabric_ca/sdk/HFCAClient.java
rickr (Wed, 29 Aug 2018 14:31:36 GMT):
getcacert ?
gravity (Wed, 29 Aug 2018 14:53:22 GMT):
so this method returns certificates for identities that are registered on ca
how these certificates differ from certificates in Enrollment object?
rickr (Wed, 29 Aug 2018 15:44:42 GMT):
Which class is that on
gravity (Wed, 29 Aug 2018 15:48:03 GMT):
HFCAClient#getHFCACertificates()
rickr (Wed, 29 Aug 2018 15:51:41 GMT):
I think those are the same certificates .. but that API allows you manage them. @skarim
gravity (Wed, 29 Aug 2018 15:55:54 GMT):
because I'm trying to figure out how to get the admin certificates from CA (special admin who can create the channels and install chaincode). because for now I see the only way is to load them from disk/db (like it done in End2EndIT.java)
and just want to know is there any way to retrieve them from a CA?
rickr (Wed, 29 Aug 2018 16:02:53 GMT):
I don't think so. I think you should ask on #fabric-ca channel
gravity (Wed, 29 Aug 2018 16:05:02 GMT):
thanks, will ask
btw, do you know any insights why it was done in this way? that we can get (enroll) any user on a CA except that special admin?
rickr (Wed, 29 Aug 2018 16:14:07 GMT):
Well for quick development environment we use cryptogen to quickly create all the cryptography artifacts. You probably wouldn't use this for a real deployment. Maybe if you had your CA running and then generated all those from it there could be a way to do what is you're wanting but I'm betting it would quite involved if it's possible.

no the sdk is to make requests to Fabric. Just like an HTTP client to a web server. I don't see why the SDK needs to persist anything to do that.

This might be out of scope. or really simple. but I've been trying various combinations of values with no success so I'm stumped.
I'm trying to add create a channel on a fabric network I (think) I deployed into kubernetes. The first thing of note it does is `Channel channel = client.newChannel(cd.getId(), anOrderer, channelConfiguration, signatures);` and it fails here. I'm failing ultimately on this - `Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target`
I usually get round it by having a hostname override in the properties, but in this case it is not working. Security isn't my thing -

I'm trying to create a channel on a fabric network I (think) I deployed into kubernetes. Standard cryptogen self generated certificate fare. The same stuff works fine in docker.

I usually get round it by having a hostname override in the properties, but in this case it is not working. I know I'm hitting my orderer - I get this in the logs: `2018-08-31 01:34:52.673 UTC [grpc] Printf -> DEBU 1ae grpc: Server.Serve failed to complete security handshake from "127.0.0.1:36320": remote error: tls: internal erro`.
The logs seem to indicate that when this orderer comes up it is finding all the files correctly so I'm a bit out of my depth here.

@Chaos-WX Most likely your tls server cert you're connecting does not match. If this is a development env you can use hostname override.

Hi all
If I use orderer1 to create channel1, can I add orderer2 to channel1 during channel initialization?
gravity (Fri, 31 Aug 2018 12:52:21 GMT):
btw, I'm using solo mode for orderer. or am I doing something wrong?
I mean, if orderer is in solo mode, so there must be at most 1 orderer instatance, isn't it?
rickr (Fri, 31 Aug 2018 12:54:07 GMT):
There should be no reason for more than one Orderer other than for redundancy sake
gravity (Fri, 31 Aug 2018 12:58:32 GMT):
you mean for solo mode? or should it be only one orderer in kafka mode?

rickr (Fri, 31 Aug 2018 14:52:53 GMT):
can you run that with docker and see what it returns .. for me the CN as orderer0.orderer _looks odd_
rickr (Fri, 31 Aug 2018 14:54:18 GMT):
never mind that
rickr (Fri, 31 Aug 2018 14:58:35 GMT):
You may need for the s_client -servername name for the hostname override. @ashutosh_kumar ?
aatkddny (Fri, 31 Aug 2018 14:59:28 GMT):
It's set that way due to the kubernetes not allowing `.` in something or other. The config file for the orderer is amended in the same manner.
```
OrdererOrgs:
- Name: Orderer
Domain: orderer
Specs:
- Hostname: orderer0
- Hostname: orderer1
- Hostname: orderer2
```
ashutosh_kumar (Fri, 31 Aug 2018 15:00:13 GMT):
first , it looks like mutual TLS is on on Server and somehow client is not sending cert.
rickr (Fri, 31 Aug 2018 15:00:37 GMT):
need to step away
ashutosh_kumar (Fri, 31 Aug 2018 15:08:47 GMT):
so you have to use -cert <> to pass your client cert.
ashutosh_kumar (Fri, 31 Aug 2018 15:15:42 GMT):
and -CAfile <>
ashutosh_kumar (Fri, 31 Aug 2018 15:16:47 GMT):
you need to fabricate a pem file where you cut and paste from pem files related to CAs that you are using.
ashutosh_kumar (Fri, 31 Aug 2018 15:17:08 GMT):
hopefully this should work.
ashutosh_kumar (Fri, 31 Aug 2018 15:19:27 GMT):
your error is related to cert chain validation , not hostname.
ashutosh_kumar (Fri, 31 Aug 2018 15:19:43 GMT):
validation.
ashutosh_kumar (Fri, 31 Aug 2018 15:20:41 GMT):
this error : No client certificate CA names sent : Suggest that you need to send client cert to server.
aatkddny (Fri, 31 Aug 2018 15:22:09 GMT):
You've lost me with the client cert. I'm approaching this from what I do with regular fabric and without specialized ssl knowledge. We VPN everything we can...
Cryptogen creates self signed certs. I bring up the orderer with what's in the generated .../{name}.{domain}/tls directory.
To call this from the SDK requires me to set a couple of properties
I use /server.crt from the same /tls directory for the PEM.
I also pass a hostname override of {name}.

After that it just works. If I omit the hostname override it doesn't.

Ok that's docker. For k8s I had to change orderer.com to orderer and anything in a name with a . to a -
The thing comes up but I can't talk to it in the same way
ashutosh_kumar (Fri, 31 Aug 2018 15:23:05 GMT):
hmm.
ashutosh_kumar (Fri, 31 Aug 2018 15:24:42 GMT):
I am not familiar with java sdk code. I have to take a look to understand what you are doing from config perspective.
ashutosh_kumar (Fri, 31 Aug 2018 15:25:28 GMT):
so , when you do test from Java SDK , what error you get ?
aatkddny (Fri, 31 Aug 2018 15:27:18 GMT):
the original one i posted - Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
ashutosh_kumar (Fri, 31 Aug 2018 15:28:20 GMT):
so , openssl and java errors are almost same.
ashutosh_kumar (Fri, 31 Aug 2018 15:28:34 GMT):
your issue is related to cert config
aatkddny (Fri, 31 Aug 2018 15:28:43 GMT):
Right.
So here's what I pass to the env in k8s
aatkddny (Fri, 31 Aug 2018 15:28:43 GMT):
Right.
So here's what I pass to the env in k8s
```
- name: ORDERER_GENERAL_TLS_ENABLED
value: "true"
- name: ORDERER_GENERAL_TLS_PRIVATEKEY
value: /share/generated/crypto-config/ordererOrganizations/orderer/orderers/orderer0.orderer/tls/server.key
- name: ORDERER_GENERAL_TLS_CERTIFICATE
value: /share/generated/crypto-config/ordererOrganizations/orderer/orderers/orderer0.orderer/tls/server.crt
- name: ORDERER_GENERAL_TLS_ROOTCAS
value: /share/generated/crypto-config/ordererOrganizations/orderer/orderers/orderer0.orderer/tls/ca.crt
```
ashutosh_kumar (Fri, 31 Aug 2018 15:31:16 GMT):
what you have on java sdk ?
aatkddny (Fri, 31 Aug 2018 15:31:23 GMT):
It won't accept an array for `ORDERER_GENERAL_TLS_ROOTCAS` but I can't see how that affects things.
The client uses `/share/generated/crypto-config/ordererOrganizations/orderer/orderers/orderer0.orderer/tls/server.crt` as the PEM as described above.
That's the same file I was using in -CAfile in the openssl calls.

It's passed in as a byte array in a property called "PEMBYTES"
ashutosh_kumar (Fri, 31 Aug 2018 15:33:30 GMT):
i'll be back in an hour or so.
ashutosh_kumar (Fri, 31 Aug 2018 15:33:38 GMT):
going for lunch.
aatkddny (Fri, 31 Aug 2018 15:34:07 GMT):
I'm wondering if there's a hardcoded expectation somewhere down the line in security that domain requires a `.` since that's the only real change between this and the docker version. That uses orderer.com instead of orderer and works.
ashutosh_kumar (Fri, 31 Aug 2018 15:34:10 GMT):
I'll look at Java SDK code
ashutosh_kumar (Fri, 31 Aug 2018 15:34:50 GMT):
hmm. Not sure.
ashutosh_kumar (Fri, 31 Aug 2018 15:34:59 GMT):
need to look at SDK code.
aatkddny (Fri, 31 Aug 2018 15:35:14 GMT):
This is the call - `Channel channel = client.newChannel(cd.getId(), anOrderer, channelConfiguration, signatures);`
aatkddny (Fri, 31 Aug 2018 15:35:23 GMT):
client is HFClient.
ashutosh_kumar (Fri, 31 Aug 2018 15:35:28 GMT):
ok.
ashutosh_kumar (Fri, 31 Aug 2018 15:35:34 GMT):
thanks.
rickr (Fri, 31 Aug 2018 16:30:17 GMT):
There's nothing in the SDK code that checks or does anything with a `dot`
rickr (Fri, 31 Aug 2018 19:08:24 GMT):
@aatkddny I just found this looking at another issue ... maybe see if it's helps you ... when start the java vm add this property : ` -Djavax.net.debug=all` .. but please don't hold me to know what it puts out .. your on your own :)
aatkddny (Fri, 31 Aug 2018 19:51:40 GMT):
debug=ssl does just the ssl stuff - but it's not actually printing anything extra at this point for some reason.
I tried it last night.
But I do appreciate the thought though.
aatkddny (Fri, 31 Aug 2018 19:51:40 GMT):
`-Djavax.net.debug=debug=ssl` does just the ssl stuff. I tried it last night. The problem is that it doesn't actually put out anything more than the regular version does in this case - it never gets far enough into it for all the additional logging to trigger. But I do appreciate the thought though.
A little more googling this afternoon and it looks like there's a CA with a set of certificates inside the k8s cluster somewhere that needs to be appeased (or integrated). Personally I prefer appeased.
Since it's part of the security voodoo that means I'll probably have to sacrifice a goat or a chicken at a crossroads at the next full moon to get it all squared away.
On a happier note if I turn off TLS I *can* hit the orderer and it does what it's supposed to, so for purposes of what I'm actually trying to do - which is duplicate my docker network inside kubernetes so I can extend it to multiple servers - I think I'll run the whole thing without TLS until such time as it all is running happily in there and revisit it then.
@rickr @ashutosh_kumar - thanks for the assist.

No. There are settings on the channel config block that can alter the `batch` size.

so admin and peer does not work

there is some limitation in the sdk policies?
dharuq (Sat, 01 Sep 2018 16:35:27 GMT):
Hi! in the sdk is anyway to know how many transactions are done per second?
rickr (Sat, 01 Sep 2018 18:11:13 GMT):
The SDK does not track any performance measurements.
rickr (Sat, 01 Sep 2018 18:14:26 GMT):

Ok so I have some issue with this setup. Getting this ```DEBU 41b start container: aacc:1.0

Which doesn't surprise me because this whole go and shove fabric into kubernetes deal is a giant rabbit hole, but I don't see anything saying there's an issue with security per se.

Leaving aside my travails, is this an expected response? I'd have thought to see something that more closely mirrors the errors from the peer.

Hi, I have a functional application that uses Hyperledger Composer to interact with MultiOrg Fabric network. However, I want to start using java sdk for this application. I've tried searching references that could help me getting started. I found few of them that helped me understand the functions that SDK offers but not more than that. Is there any reference available that can help me understand this in a better way?

Stand up a fabric network. Create a channel. Life is good.
Stop and restart the peers. They come up. So far so good.
Try to rejoin the previously created channel. Not so good.
Channel rejoin code is the same as the reconstruct logic - join peers to channel object and do an initialize.
SDK throws an access denied exception - `Sending proposal to peer1-org failed because of: gRPC failure=Status{code=UNKNOWN, description=access denied: channel [channel] creator org [msp], cause=null}` - msp and channel here are redacted but correct.
Peer throws this `2018-09-05 15:04:30.479 UTC [protoutils] ValidateProposalMessage -> WARN 15d7 channel [channel]: MSP error: channel doesn't exist` before all hell breaks loose (it starts throwing hundreds of peer event errors).
Channel was created just fine. I can see it in my orderer logs - here's two that seem pertinent - start and (as far as I can tell) end of the create

TLS is off. Crypto is unchanged between restarts.
Peer storage persists and was untouched.
Do I need to join the channel differently in the case of a peer restart like this or is there some issue?

I'm not too bright. I'm testing using a different containerization setup and all my peers were misconfigured to have transient ledgers. Forgot a mount.
The peers were all pulled out at the same time to try a slightly different configuration. Transient ledgers in all mean there's no way I can see to reconstitute world state, so that was likely the cause.
And I was adding the peers - I wasn't precise enough in my language. The code is a direct port of the reconstruct in whichever End2End test I found it.
I deleted the original post before seeing this response. I'll retry with persistent ledger storage and hopefully that'll fix the problem.

silliman (Wed, 05 Sep 2018 19:09:41 GMT):
@kisna java chaincode was available in Fabric v0.6 but Fabric v1.x was a major rewrite with significant architectural differences from v0.6. As a result, java chaincode was removed from v1.x because it was not deemed production-ready by the release managers. It looks as if now it will return for Fabric v1.3.

when I have added BouncyCastle as a provider via java.security.Security.addProvider. AFAICT its related to the loop mechanism here: https://github.com/hyperledger/fabric-sdk-java/blob/master/src/main/java/org/hyperledger/fabric/sdk/security/CryptoPrimitives.java#L225 and the fact that an exhaustive search is done with providers, and if any throw an exception, the exception is rethrown, rather than an exception being rethrown IFF no providers are able to verify the X.509

alternatively, i'd be happy to extend TransactionRequest and provide a doVerify() {return false;}, but https://github.com/hyperledger/fabric-sdk-java/blob/master/src/main/java/org/hyperledger/fabric/sdk/Channel.java#L3410 only accepts QueryByChaincodeRequest, which extends TransactionRequest, doesn't allow doVerify config, and has a private constructor, preventing further extension.
MikeEmery (Wed, 05 Sep 2018 21:16:38 GMT):
@mrkiouak I've run into that as well, the cause appears to be a chaincode exception resulting in an empty endorser certificate PEM (since the request wasn't endorsed). Seems like the SDK should be checking before attempting to read the certificate

how do i check out 1.2.1-SNAPSHOT (it doesn't appear to be in public repos). a `mvn install` from master gives 1.3.0-SNAPSHOT, but I don't see any tags or branches that jump out to me as the 1.2.1-SNAP
mrkiouak (Wed, 05 Sep 2018 21:38:57 GMT):
ah, apologies, checking out and installing the release-1.2 branch did it

Hi All, I have a question regarding setting up a multi org endorsement client application. I want to send a transaction proposal request to 2 different organisations(since the endorsement policy is AND(Órg1MSP.member', 'ORG2MSP.member'). How is this possible when the hfclient, from which you build a channel with .newChannel(), sets the usercontext to an User which is bound to a enrollment which in turn is bound to an CA via HFCAClient?
laurensdegilde (Thu, 06 Sep 2018 12:59:06 GMT):
Do you just build multiple channels for each organisation and than collect the ProposalResponses as 1 collection after which you send that collection to the orderer?
laurensdegilde (Thu, 06 Sep 2018 12:59:15 GMT):
Seems kind of inconvenient to me....
laurensdegilde (Thu, 06 Sep 2018 13:15:16 GMT):
Sorry that is not possible either since you send the responses via a channel object to the orderer. Probably the responses than dont have the correct signature
tkg (Thu, 06 Sep 2018 13:47:46 GMT):
@laurensdegilde you send the transaction proposal request to the endorsing peers (many orgs), then the responses to the orderer

laurensdegilde (Thu, 06 Sep 2018 14:17:06 GMT):

agreed, peers pull data from Kafka instead of ordered pushing data to peers,

silliman (Fri, 07 Sep 2018 02:40:29 GMT):
@kisna 4Q) I don't know 3Q) in a properly functioning system your peers shouldn't be out of sync much more than what would be expected to be caused by network latency inherent in any distributed system- that is, it is impossible to guarantee that every peer is in the same state at the exact same point in time. Best practice in an app would be to retry a few times if you are receiving different results due to network latency. If your peers are grossly out of sync that could be indicative of larger problems. Peers do not talk to each other during the endorsing phase- each peer that your client app targets simulates its results independently. Your client app or the SDK will be the one to determine that the results match in accordance with your endorsement policy. Peers do not talk to each other during the validation phase when validating public data however with the introduction of private data peers may use gossip to get private data from other peers as appropriate and needed
kisna (Fri, 07 Sep 2018 02:41:40 GMT):
I am asking this because, isn't the fundamental premise of blockchains to keep all peers with same data after consensus?

silliman (Fri, 07 Sep 2018 03:30:25 GMT):
Peers use the gossip protocol to keep track of their block height e.g. they will at times randomly send their block height to other peers they know about, and if the receiving peer has a lower block height it may ask for the blocks it deduces it is missing. But they do not compare contents with each other within the blocks and try to reconcile any differences. I do not know the nature of your test but if you are saying that the value of key 'b' is 1004 in peer1 and is 999 in peer0 then I am saying that either your two peers were at different block heights at the point in time when these queries were made, or there is something else fundamentally wrong with either your network, or your test.
kisna (Fri, 07 Sep 2018 03:43:27 GMT):
got it, so peers do exchange missing data before "Step 6" or writing new blocks?
kisna (Fri, 07 Sep 2018 03:43:36 GMT):
to make sure they are at same height?
silliman (Fri, 07 Sep 2018 03:46:05 GMT):
peers can receive missing blocks from other peers via the gossip protocol but that process is independent of the transaction flow

@RockyRacer You need to construct the channel. IMO the best way to start out is get the integration test working. See the readme.md Read the README.md at least once, maybe twice :) Then spend a half a day with a debugger and follow the integration tests. Debugging is best as I'll be the first to admit the code is little difficult to just follow, but seeing the variables and stepping through goes a long way in helping. You can then easily copy from this code parts that can get what you need done.

Hey Folks. I'm new in here and having trouble picking up JAVA vs Node SDK. can you guys help me make a choice? Considering Fabric is written in GO? my predilection is towards java btw

anyone who has used both the SDK's your thoughts will be insightful.

kid101 (Tue, 11 Sep 2018 20:14:37 GMT):
also are there any plans to incorporate java samples in the docs as well.. It would certainly be helpful :angel_tone1:

@kid101 Read the Readme.md .. maybe read it again would be a good start.

where can i find tutoriales about building an hyperledger fabric app with java?
RockyRacer (Wed, 12 Sep 2018 06:36:54 GMT):
Seem that there is no documentation, no function reference, no tutorials, etc.... You just need to go through provided examples (https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric/) and spend hours to try to extract what you need !
RockyRacer (Wed, 12 Sep 2018 07:23:12 GMT):
well, still not able to create channel, `client.getChannelConfigurationSignature(channelConfiguration, user)` returns the following:
```
org.hyperledger.fabric.sdk.exception.InvalidArgumentException: com.google.protobuf.InvalidProtocolBufferException: While parsing a protocol message, the input ended unexpectedly in the middle of a field. This could mean either that the input has been truncated or that an embedded message misreported its own length.
```

@rickr Hi, rickr, as we know, sdk takes the user’s cryptographic credentials to produce a unique signature for transaction proposal, but sometimes we want to do this out of the sdk, it means the business app has produced a sdk external signatrue. I find there is not api to achieve my demand. Could you help me. Thanks.
rickr (Wed, 12 Sep 2018 10:46:26 GMT):
@fanjianhang The SDK purpose is *mostly* installing, invoking chaincode and then sending them to the Orderer. In the process it does sign and verify proposals and transactions. There's no API to send some _raw_ data. if that's what your suggesting.

rickr (Wed, 12 Sep 2018 10:50:04 GMT):
@RockyRacer There's javadoc and the integration tests which are really examples if you will that do almost everything the SDK is designed to do. How did you get your channel configuration ?
RockyRacer (Wed, 12 Sep 2018 11:31:38 GMT):
@rickr I generated channel configuration transaction using configtxgen, then I do the following as in the end2EndIT integration test example:
```
String fileName = "channel.tx";
ClassLoader classLoader = this.getClass().getClassLoader();
File channelTx = new File(classLoader.getResource(fileName).getFile());
ChannelConfiguration channelConfiguration = new ChannelConfiguration(channelTx);
newChannel = client.newChannel(CHANNEL_NAME, client.newOrderer(ORDERER_NAME, ORDERER_ADDRESS, properties), channelConfiguration, client.getChannelConfigurationSignature(channelConfiguration, user));
logger.info("Created channel " + newChannel.getName());
```
RockyRacer (Wed, 12 Sep 2018 11:32:49 GMT):
error is raised by `getChannelConfigurationSignature`
rickr (Wed, 12 Sep 2018 11:42:03 GMT):
Can `simplify` the code so that right now you're using the fullpath to channel.tx to make sure your referencing the right file .. just to test -- not likely but should be simple try.. Or print it out ? There is also sdk logging from the README.md
```
Logging for the SDK can be enabled with setting environment variables:
ORG_HYPERLEDGER_FABRIC_SDK_LOGLEVEL=TRACE
```
Not sure how good we did there in logging but maybe that can help ?

@rickr Do you support adding a private data definition after channel creation or is that something that I'd need to code for (like adding an org to the channel).
rickr (Fri, 14 Sep 2018 14:48:39 GMT):
I'm not sure what you mean by `private data definition` There is private data collections on chaincode. There is an example of that with ->
https://github.com/hyperledger/fabric-sdk-java/blob/ef604d1fd3bc12eeed9910036f24e4a4953156c4/src/test/java/org/hyperledger/fabric/sdkintegration/PrivateDataIT.java
aatkddny (Fri, 14 Sep 2018 15:50:14 GMT):
I meant defining a private data collection and adding it to the channel AFTER the channel has already been created. I saw the one at channel create time, but you don't always know up front who needs what.

I saw the one at channel create time, but you don't always know up front who needs what. I'm in the told it can be done - and I'm trying to find out what's involved - but I wondered if there was support for it natively in the SDK.
rickr (Fri, 14 Sep 2018 16:13:41 GMT):
I'm not aware of private data collection on a Channel. So if something like that exists .. no the SDK does not have it. -- I'll ask around. The SDK has as I pointed out an api for private data collections on chaincode.
rickr (Fri, 14 Sep 2018 16:21:32 GMT):
I think we or maybe I am getting confused on terminology :) The private data is just a hash on the ledger ( aka channel) but the way that's created and defined is when you Instantiate chaincode or upgrade. Then your chaincode uses special api to access that .. that is in the sample link above
rickr (Fri, 14 Sep 2018 16:23:52 GMT):
to be honest right now I see the JSDK we did test that on instantiate chaincode .. but probable didn't explicitly on chaincocode upgrade .. please feel free to be our gunea pig :)

@rickr Was just wondering about an architectural question. I have multiple peers running on different machines - all connecting to the same channel. After each peer joins the channel, I save the state . When I recreate the channel (say in Machine A having Peer A), is there any way that I can know about the peers in Machine B and C (Assuming that they have already joined the channel) - This is important because when we invoke ```
`Collection responses=channel.sendInstantiationProposal(instantiateProposalRequest,channel.getPeers());`
```

The other peers in the different orgs or even the same would just `add` not join to the channel
rickr (Fri, 14 Sep 2018 18:55:32 GMT):
You only ever once `join` a peer to the channel irregardless of any system you're on. After that on another system or if you reconnstructing the channel you would just ever `add` it.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=jMQ2g9uoAZKQHRqhn) I'll give it a whirl next week. Now I'm wondering what that means for collections across CC versions. Guess I'll find that out too.
yacovm (Fri, 14 Sep 2018 23:22:48 GMT):
@aatkddny - collections across chaincode versions don't mean anything special.
a chaincode "version" with respect to the channel data, is simply a means to bind the chaincode code hash to the channel.
so, when you change the chaincode version - you don't change the data, therefore the collection stays the same.

Hi folks. I am new here. I sent a mail to the mailing list and the suggestion was to ask here... I have multiple orgs setup on different servers. (Say ORG-a and ORG-B). Using the java-sdk, I create a channel (HFClient.newchannel) on ORG-A. Now in ORG-B do I need to create the channel again? Seems to defeat the purpose. HFClient.getChannel() returns null. Is there a way that I can retrieve the channel already created? Of course while creating the channel in ORGA, I have added the config for ORGB also. In the CLI this seems to be quite straightforward. I am not able to understand the same feature in java-sdk

Take a look at this first https://github.com/cr22rc/fabricSDKJavaMultiDomainSample
rickr (Sat, 15 Sep 2018 12:19:15 GMT):
You can't `query` if there is a channel. You create it once, you join the peers once. As READM.md suggest take the time to follow the End2endIT and then End2endAndBackAgainIT will help

Read through the README.md once maybe even twice will also beneficial

mattremy (Sat, 15 Sep 2018 17:50:49 GMT):
@rickr thanks for the input. I have gone through the examples that you have provided. My apologies for being pedantic in advance - I have created a channel in OrgA and then recreated the channel in orgB. However, if I query the channel in ORGB(With channel.getPeers()), it doesn't return the peers already joined from ORGA. Is that the intended way?
rickr (Sat, 15 Sep 2018 18:48:16 GMT):
That method _only_ returns the peers you've joined or added to the channel object.
mattremy (Sat, 15 Sep 2018 19:18:07 GMT):
@rickr Thanks once again. Is there any way to retrieve peers of ORGA that have joined the channel from ORGB? I have gone through both End2EndIT and Backagain. Unable to find. Would be grateful if you could even point me to any other location that might help me with the answer

@aatkddny what do you mean a new version of the collection?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=sj7Z4qy6JS2GhtXo8) @yacovm Let's say we were to close-couple the data with the representation inside the persisted object in the PD collection. Serialized object rather than a map for instance.
Then the project is updated for some reason and the developer decides to add or delete new properties to the object in a PD collection and update the chaincode so the old schema is invalid.
This would require that we change the data that's already there so this new version of the chaincode works.
Setting aside what an awful design pattern that is, that's what I mean by a new version of the collection here.

yacovm (Mon, 17 Sep 2018 14:49:53 GMT):
can't you just do a function in the chaincode that.... upgrades it?
yacovm (Mon, 17 Sep 2018 14:50:18 GMT):
you can always just do a new chaincode that exists only for that, and do a chaincode-to-chaincode write
yacovm (Mon, 17 Sep 2018 14:50:46 GMT):
btw @aatkddny - you need to realize asking about private data in java SDK is not going to give you max attention from private data developers
aatkddny (Mon, 17 Sep 2018 14:51:15 GMT):
Of course you can. But there's an explicit upgrade call in the CC when it is instantiated. My question was whether this was mirrored in the PD.
aatkddny (Mon, 17 Sep 2018 14:51:15 GMT):
Of course you can. But there's an explicit upgrade call in the CC for the regular data when it is instantiated. My question was whether this was mirrored in the PD.

I sometimes wander far into hostile channels such as this one, but not everyone does

> Of course you can. But there's an explicit upgrade call in the CC when it is instantiated. My question was whether this was mirrored in the PD.
I hate the upgrade/instantiate calls. And I'm not 100% sure that private data works in upgrade. I know it *does not* work in instantiate for sure
yacovm (Mon, 17 Sep 2018 14:52:13 GMT):
I can check for upgrade though
yacovm (Mon, 17 Sep 2018 14:52:35 GMT):
@dave.enyeart does private data works in upgrade simulations?
yacovm (Mon, 17 Sep 2018 14:52:45 GMT):
I recall we restricted it in instantiate

aatkddny (Mon, 17 Sep 2018 15:03:17 GMT):
@rickr Is there an sdk sample for creating db indices for cc with couchdb? This:
```
For example, for go chaincode (fabric-client/lib/packager/Golang.js) the packaged tar would include:
src/github.com/hyperledger/fabric/examples/chaincode/go/marbles02/marbles_chaincode.go
META-INF/statedb/couchdb/indexes/indexOwner.json
```
from here: `https://jira.hyperledger.org/browse/FABN-33` implies (assuming my adult literacy classes worked) that all I need to do is to shove the definitions in the same directory as the go code and the magic box handles it all. We zip the directory and pass in as an input stream though so I just wondered if it had been tested or if I'm going to be QA. I'm going to have to try it regardless, but knowing it works will help me to debug if I mess something up.
rickr (Mon, 17 Sep 2018 15:48:51 GMT):
There's no example of creating the indicies. I did a manual test at one time. I don't think there's any way to verify from the API that an index was placed on an entry.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=d6ZNCpPDLfYKQyYsC) You can see it in the couchDB DB - which I can get to easily. My problem is that I'm not sure what way I need to invoke it from the SDK.
I think there might be an oversight here.
I tried the path version of bundling it as described in the manual - put the definition in a file in `/META-INF/statedb/couchdb/indices` under the root go directory.
That didn't work.
It also talks about passing a `metadataPath` if you are using Node. And I do see - `setChaincodeMetaInfLocation`.
The problem is I'm passing the go code in with `setChaincodeInputStream`. The two seem incompatible based on the note for the former.
Did I misunderstand something here?

@rickr - so I didn't misunderstand and they are incompatible.
That throws a giant wrench in the works for me - out whole chaincode install pattern is based on being able to pass the go code as a stream rather than having to mount the CC in the containers.
Do you have any plans to support indices in the other instantiate method?

Looking to see if someone can point me to some documentation or clarify something when it comes to clients: What exactly is the role of a _user_ ? I know this probably seems like a stupid question - sorry about that - but I'm wondering because when read through the End2EndIT example it iterates through all organizations and enrolls an admin user as well as a regular user, but I'm not sure why this needs to be done for every single organization, or why you must have an admin and a regular user.

In the tar that SDK provides, META-INF must be the top level directory.

The SDK will handle the correct structuring of the META-INF if the application uses it's APIs to create it from the a source on disk. If the application's choice is to provide chaincode from a stream it's assumes the burden that the stream has it correctly structured. Every SDK should not need to document that structure @dave.enyeart that should be adequately documneted in the Fabric.

is there something similar in Java SDK to CLI `fabric-ca-client identity modify`?
for example, if I want to update attributes for a user, can I do this via Java SDK?

it could be done using `update` method from the `HFCAIdentity` class

Hi, suppose we have 3 eventhub registered. It looks like Java SDK wait for all events from eventhub for a single transaction complete. Is there anyway to specify any of eventhub ? I see setN() method in Channel.java code.
ibmamnt (Tue, 25 Sep 2018 03:08:09 GMT):
end2endMTIT.java tells us it might be possible by reading the comment below.
```
//Specify what events should complete the interest in this transaction. This is the default
// for all to complete. It's possible to specify many different combinations like
//any from a group, all from one group and just one from another or even None(NOfEvents.createNoEvents).
// See. Channel.NOfEvents

rickr (Tue, 25 Sep 2018 13:37:20 GMT):
You can create NOfEvents groupings. Be default all need to be completed; however, you an set `N` `setN` which is how many in that group need to show completion. So by default all, setN(1) = any
rickr (Tue, 25 Sep 2018 13:41:17 GMT):
@ibmamnt Also Eventhubs are going away, you should be using Peer eventing services. I don't know why people tend to look at the End2endMTIT as the README.md point to other examples. En2endMTIT is not necessarily kept up to date.
tballast (Tue, 25 Sep 2018 14:02:26 GMT):
@rickr Are EventHubs going away in 1.3? Or are they just being deprecated right now?
rickr (Tue, 25 Sep 2018 14:04:05 GMT):
The JSDK still has code to manage them for Fabric <1.3. But Fabric 1.3 no longer has Eventhub support.

Have not seen that error nor recall anyone else reporting. The only things come to mind is something interfering like firewall or not connecting to what you think are. You could look at that specific peer's log and see if it shows anything interesting.

tsnyder (Tue, 02 Oct 2018 06:17:22 GMT):
I have been working through the End2EndIT.java example (v1.2) and am having trouble understanding how to set up Peer Event Services for a particular Peer. The former way of setting up event hubs and registering a BlockEventListener now seems to generate responses from all the Peers. Questons - 1) I am presuming that for PeerEventServices I should no longer instantiate an EventHub. I see where PeerOptions has an EventSource but this seems to still be within the constraints of a Channel/Peer.
tsnyder (Tue, 02 Oct 2018 06:18:56 GMT):
2) Is there an example somewhere where we are setting a BlockEVentListener specific to a single Peer on all channels authorized on the Peer?
rickr (Tue, 02 Oct 2018 12:46:49 GMT):
@tsnyder Eventhub have been deprecated. They will no longer work with Fabric 1.3 peers. The blocklistners will get events from every peer. The events identify which peer so the application can filter.
tballast (Tue, 02 Oct 2018 14:54:11 GMT):

If your asking can you create the needed channel.tx from scratch . no.
rickr (Wed, 03 Oct 2018 12:21:01 GMT):
There have been others that have created a template one then used https://github.com/hyperledger/fabric-sdk-java/blob/8e631c1a70bd2e336aa76dfaf33fff7a29c08918/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java
to update that to create a new one.
aatkddny (Wed, 03 Oct 2018 22:25:57 GMT):
It is possible create it from scratch if you are willing to think outside the box a little and you can get the signatures of the orgs required to create the channel.
You can use some kind of templating setup to dynamically create your config file and then something like a process builder to run a configtxgen to create the channel.tx.
You can use that to create the ChannelConfiguration, after which you need to grab the signatures and create the channel. I'm pretty sure I remember cribbing from an example that was provided for that piece.

I'm getting a timeout trying to create a channel since I moved my network (and it grew).
aatkddny (Thu, 04 Oct 2018 12:13:46 GMT):
I'm getting a timeout trying to create a channel since I moved my network.
One of these - `org.hyperledger.fabric.sdk.exception.TransactionException: Getting block time exceeded 5 seconds for channel xxx`
I'm guessing I need to edit `org.hyperledger.fabric.sdk.channel.genesisblock_wait_time`.
Has anyone else hit this problem when they have a bigger network or is it a result of switching to a multi-server network and the additional delay involved there? I saw the comment in Channel about kafka not being ready and wondered if there was a way to make sure it's tee'd up with a heartbeat or similar.

I'm guessing I need to edit `org.hyperledger.fabric.sdk.channel.genesisblock_wait_time`, but I'm running in a spring boot environment and I'm finding it awkward to figure out how to insert it without making it a vm property.
Has anyone else hit this problem when they have a bigger network or is it a result of switching to a multi-server network and the additional delay involved there? I saw the comment in Channel about kafka not being ready and wondered if there was a way to make sure it's tee'd up with a heartbeat or similar.

No. But I only work with _toy_ networks! Given this is probably due to Fabric scaling you'd probably get better answers on one of their channels. #fabric-peer-endorser-committer #fabric-orderer

This isn't that big - it's for the pilot.
It's 18 orgs with 2 peers each. It didn't fit well inside a single docker image so I had to move it to kubernetes.
The problem is most likely the hypervisor for VMs that the cluster is running on seeing no activity and swapping everything out, but that's out of my control. I'm halfway through reconstituting it and I'll see if upping the wait property makes it go away.

rickr (Mon, 08 Oct 2018 11:24:55 GMT):
I think you changed something in the tests incorrectly. The ports are not the same as should be 7054 and 8054. The two Fabric CAs have a slightly different set up as can be seen by the docker-compose.yaml. For testing purposes ca0 is using a named instance `- FABRIC_CA_SERVER_CA_NAME=ca0` while ca1 is not. I think somehow in what changes you did you got them possibly crossed and the test would fail as shown above.

Hi! At what point can I be 100% sure that my transaction has been added to the ledger? Is it when I get a Future back and that Future report OK? Or do I need to do further checks?
What is a fast way to fetch the history of a key? Would I have to go through the whole ledger if I want if for a few keys?

In End2endIT in fabric-sdk-java, some containers failed to start after./fabirc up so that SDK ran out of operation.

Why does `blockInfo.transactionCount()` returns 0, while `blockInfo.getEnvelopeCount()` returns 1 and envelopeInfos contains transaction info ?
rickr (Tue, 09 Oct 2018 11:10:27 GMT):
Most likely an update/config block
rickr (Tue, 09 Oct 2018 11:19:48 GMT):
@emiliastk The transaction is on the ledger of the peers you're listening to with peer eventing services or eventhubs when the future is cleared. There's some chance it's not cleared yet on any other peers. You shouldn't need to do any other checks -- but wouldn't hurt :) From the SDK I think only going through the blocks and transaction would get you the history of the keys. There may be a better way to do that in chaincode ( ask on: #fabric-java-chaincode )
RockyRacer (Tue, 09 Oct 2018 11:27:56 GMT):
Ah ok it make sense, thx
rickr (Tue, 09 Oct 2018 12:13:46 GMT):
@emiliastk Was just told of `GetHistoryForKey()` chaincode api I've not done much with it so not sure if it fits your needs. You could write chaincode that calls that and returns that information.
emiliastk (Tue, 09 Oct 2018 20:48:59 GMT):

@emiliastk
I didn't write this so I'm not saying it's the best Go code ever written (but it does work). You can crib from this as a start if it helps.
```

var err error
historyIterator, err = api.GetHistoryForKey(id)
defer historyIterator.Close() // ensure to close after this function is done
if err == nil {
var v interface{}
result := make([]interface{}, 0)
for historyIterator.HasNext() {
keyModifiction, err := historyIterator.Next()
if err == nil {
assetHistory := AssetHistory{}
assetHistory.TxID = keyModifiction.GetTxId()
assetHistory.Timestamp = time.Unix(keyModifiction.GetTimestamp().Seconds, int64(keyModifiction.GetTimestamp().Nanos)).String()
assetHistory.IsDelete = keyModifiction.GetIsDelete()
json.Unmarshal(keyModifiction.Value, &v)
assetHistory.Value = v
result = append(result, assetHistory)
} else {
return jsonBytes, err
}
}
jsonBytes, err = json.Marshal(&result)

@tkg The SDK does all the signing needed for endorsing proposals and transactions.
ShobhitSrivastava (Thu, 11 Oct 2018 11:03:03 GMT):
Hey @rickr ..I am stuck in one of the issue. It is I have to get endorsement from two peers. These 2 peers are in different org. In java sdk i add two peer in one channel and invoke a code. But in "consistencyGroups" it is more then 1 and hence I am getting exception. How should i get endorsement form two peers.
rickr (Thu, 11 Oct 2018 11:28:31 GMT):
@ShobhitSrivastava I'm not sure what your exact issue is given the description. I have created an application that illustrates getting endorsements from two orgs
https://github.com/cr22rc/fabricSDKJavaMultiDomainSample
_Usually_ the inconsistency like that is not because of multiple orgs but because the chaincode on each peer is writing something different to the ledger.
ShobhitSrivastava (Thu, 11 Oct 2018 11:33:25 GMT):
thanks @rickr for the reply. I will check that, In chaincode I am actually creating time in UTC in each peer which could be giving different output as chaincodes would be getting invoked in delay of few seconds? Can this be the problem for this?
rickr (Thu, 11 Oct 2018 11:33:57 GMT):

`Caused by: java.security.cert.CertificateException: No subject alternative DNS name matching localhost found.`
I've added peers to channel using peer `crt` and `key` certificates and as long as I run an application on my local machine, peer location looks like this:
`hfClient.newPeer("peer1-default-org", "grpcs://localhost:6004", properties);`
6004 is mapped to 7051 port on peer's container.
am I doing something wrong?

https://github.com/hyperledger/fabric-sdk-java/blob/release-1.2/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java
but in my case, I've updated the `Application.groups` block by adding an information about a new organization

With Oracle moving to a paid licensing model, what are the plans for java versioning going forward? OpenJDK?
rickr (Thu, 18 Oct 2018 12:39:57 GMT):
We test with OpenJDK. The JSDK doesn't ship with any JRE . Off the bat not connecting how any Oracle licensing would impact it.
aatkddny (Thu, 18 Oct 2018 13:02:13 GMT):
because we currently use oracle's java 8 rather than openjdk. But since Larry needs a new island starting with the next major release we will be switching to an open version. I wanted to be sure we weren't going to be the guinea pigs for testing jvm compatibilities.
gravity (Thu, 18 Oct 2018 13:07:12 GMT):
currently we are running the application on OpenJDK and everything is fine, have not noticed anything wrong with it

Hi, didn't find a comment in the code. But why has the peer object in the java-sdk only one channel? When we want to join the peer to another channel it will throw an exception, because it's already in one? Because HFL without the sdk allows one peer in more channels
rickr (Thu, 18 Oct 2018 13:10:49 GMT):
yes you need a new instance of a peer object for each channel
rickr (Thu, 18 Oct 2018 13:10:49 GMT):
yes you need a new instance of a peer object for each channel .. Think of it as just the connection .. it really the same peer. :wink:

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=RLQPM2eyfc3j8j5at) @halilkalkan when you say it doesn't work you mean that the attribute is not registered for that identity or that when you enroll it does not show in the enrollment certificate?
RockyRacer (Thu, 18 Oct 2018 15:31:03 GMT):
Simply have to exclude guava dependency from the hyperledger dependency, then upgrade jaxb and javassist versions for java 11, and it seems hyperledger works great with OpenJDK 11 :)
kesavants (Thu, 18 Oct 2018 18:28:28 GMT):
In scenario where service layer using java sdk registers block listener and chaincode listener and start receiving events. But when the application shutsdown and restarts it start receiving the blocks which was already received and processed. Is this as per design if so is there a way to specify start block to listener?
rickr (Thu, 18 Oct 2018 20:10:40 GMT):
chaincode events ?
kesavants (Thu, 18 Oct 2018 20:12:55 GMT):
sorry block events
rickr (Thu, 18 Oct 2018 20:14:08 GMT):
eventing peer or eventhubs ?
rickr (Thu, 18 Oct 2018 20:14:42 GMT):
You should always just get the last block each time you connect
rickr (Thu, 18 Oct 2018 20:14:59 GMT):
for eventing peers
kesavants (Thu, 18 Oct 2018 20:18:16 GMT):
Ok thx was looking at PeerEventServiceClient given Ab.SeekPosition.Builder start = Ab.SeekPosition.newBuilder();
if (null != peerOptions.getNewest()) {
rickr (Thu, 18 Oct 2018 20:20:49 GMT):
IMO the best strategy would record the block # and only act on newer blocks

kesavants (Thu, 18 Oct 2018 20:29:52 GMT):
Is this controlled via PeerOptions I see newest set to true without any setter for this. Also there is a problem if al blocks are delievered for example if I have 100k blocks and I start my service layer it will be load on the peer to deliver all these events
kesavants (Thu, 18 Oct 2018 20:31:56 GMT):
peerOptions.getNewest() will always be Boolean.TRUE as there is no setter no?
if (null != peerOptions.getNewest()) {
start.setNewest(Ab.SeekNewest.getDefaultInstance());
} else if (peerOptions.getStartEvents() != null) {
start.setSpecified(Ab.SeekSpecified.newBuilder().setNumber(peerOptions.getStartEvents()));
} else {
start.setNewest(Ab.SeekNewest.getDefaultInstance());
}

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=ueNYsTuwwt6zdgpDT) @halilkalkan from the chaincode perspective, idemix is limited in what attributes you can get in chaincode. Right now the only attributes for idemix you can get in chaincode is 'role' and 'ou'. X509 allows for custom attributes and then you can access those in chaincode.

Hi guys, my name is Aarsh. We use Hyperledger fabric backed by CouchDB to store records with a lot of text.

I believe hyperlerdger fabric peers provide something called 'event services' which publish events every time it writes to the ledger.

@gravity My guess is the operation you're doing is with credentials that don't have reader/writer permission on that channel.
rickr (Mon, 22 Oct 2018 13:51:48 GMT):
@AsifJaved You would have to use the JSDK in a webapp that handled the HTTP requests you wanted.
rickr (Mon, 22 Oct 2018 13:59:09 GMT):
@aarshleadiq The JSDK handles both. You register a block listener which has what the source of the event was either a peer event service or an eventhub which is no longer supported in Fabric 1.3. Most everything the JSDK is done in the integration tests. https://github.com/hyperledger/fabric-sdk-java/blob/0c6ff37b5de29501f885f7b7fe22c3e491fbe323/src/test/java/org/hyperledger/fabric/sdkintegration/End2endAndBackAgainIT.java#L813-L847

Looking at java code comment for "ChaincodeEventListener should not be long lived as they can take up thread resources". Looking at source looks like the listener is called in a separate thread client.getExecutorService().execute(() -> chaincodeEventListener.received(handle, blockEvent, ce)); and the HFClient executor service is a unbounded threadpool (Integer.MAX). Does it make sense to size the threadpool via config settings so that service layer can make use of this useful feature for long lived applications

@rickr Thanks for your suggestion. I do get the block events feed now. However, I am interested in the 'asset definition' or the 'data' that was committed to the ledger so I can index it in elastic search. However, the block data in the event is just a list of bytes. Even a conversion of the entire block data to string using UTF8 returns a result with some weird symbols:
```
-----END CERTIFICATE-----
kC��I`����DD(_5��9��SBI�

However, I am interested in the 'asset definition' or the 'data' that was committed to the ledger so I can index it in elastic search. However, the block data in the event is just a list of bytes. Here's the proto definition in the sdk:
```
message Block {
BlockHeader header = 1;
BlockData data = 2;
BlockMetadata metadata = 3;
}
message BlockData {
repeated bytes data = 1;
}
```

aarshleadiq (Tue, 23 Oct 2018 06:50:37 GMT):
I can see that the 'asset definition' json I am interested in is part of the block data somewhere :
```

$265af2b1-078b-49d3-b592-a0c3130794f4�{"id":"265af2b1-078b-49d3-b592-a0c3130794f4","version":4,"name":{"first":"Aarsh","middle":"Manohar","last":"Shah","fullName":"Aarsh Manohar Shah"}...
```
aarshleadiq (Tue, 23 Oct 2018 06:51:11 GMT):
But I can't figure out how to extract that particular json from the block data and parse it. Any suggestions ? :(
aarshleadiq (Tue, 23 Oct 2018 06:51:59 GMT):
I think the block events feature is designed more around metadata consumption and use (Is transaction valid, has it been committed ?) rather than consuming the actual asset that's written to the ledger.
rickr (Tue, 23 Oct 2018 14:50:56 GMT):
@aarshleadiq Example of handling Blockevents is in the integration tests
RockyRacer (Tue, 23 Oct 2018 15:35:34 GMT):
Is there any way to specify _pemFile_ other than with the file path (from the integration tests : `testprops.setProperty("pemFile", System.getProperty("user.dir") + "/src/test/resources/keypair-signed.crt");`) ? I mean using InputStream, byte[], String, ...
RockyRacer (Tue, 23 Oct 2018 15:36:23 GMT):
From inside a Spring Boot jar it forces creating temporary file just to get a path
RockyRacer (Tue, 23 Oct 2018 15:37:30 GMT):
Also where can I find all the available properties (pemFile, hostnameOverride, sslProvider, etc.) ?
rickr (Tue, 23 Oct 2018 16:19:27 GMT):
@RockyRacer yes
RockyRacer (Tue, 23 Oct 2018 19:11:20 GMT):

Hi guys! We're developing a solutions (using JSDK) thats allows organizations trade tokens between them.
To achieve this we need check whether the organization that will receive the token is registered and is a valid member of network.
There is an API or method to check the members of network? Like the "getOrganizations" method of Node SDK?
rickr (Thu, 25 Oct 2018 00:00:00 GMT):
@fhmarino There's no conveniet api for that right now. You could get the config block and parse it or use the configtxlator api to convert it to jason and then parse that. You can open a JIRA requirement for it.

You should not have to deal with the protobuf
aarshleadiq (Thu, 25 Oct 2018 02:32:58 GMT):
Ahh.. I see. So if I am only interested in write events,
1) is there a way to only subscribe to the write events ?
2) I currently get two events for every write. I suspect one is chaincode event, other is the channel/ledger event. Can I filter out the chaincode event ?
rickr (Thu, 25 Oct 2018 02:34:04 GMT):
No no filter means
rickr (Thu, 25 Oct 2018 02:34:48 GMT):
you can register separately for blockevents and chaincodevents
aarshleadiq (Thu, 25 Oct 2018 02:36:59 GMT):
I see. So, registerBlockListener is for block events, right ? I wonder why I get two events on every write
aarshleadiq (Thu, 25 Oct 2018 02:37:10 GMT):
One event contains the data I sent to chaincode in proposal
aarshleadiq (Thu, 25 Oct 2018 02:37:37 GMT):
The other event contains data that the chaincode persists to the ledger

rickr (Sat, 27 Oct 2018 16:32:24 GMT):
@aatkddny Not really working today -- but quick thing to try: You can turn off the consistency check on the SDK side dig through config.java for how to do that. ... Let it go through see what happens.

I've changed nothing. That's what's so baffling here.
aatkddny (Sat, 27 Oct 2018 18:09:37 GMT):
I *thought* I'd changed nothing, but that's not the case. This has config and crypto generated by the configxtgen and cryptogen at level 1.3 but it's running in a 1.2 network environment. I'll revert to 1.2 for the binaries and see if that's the issue.

EDIT: It isn't. A network with 1.2 binaries is having the same issue.
aatkddny (Sat, 27 Oct 2018 18:51:38 GMT):
And to close this that's of course exactly what it was. The configuration binaries aren't backwards compatible. Have a good weekend.
albert.lacambra (Sun, 28 Oct 2018 15:36:48 GMT):
Yes @rickr . That is what it looks like. I am copying all docker parameters from your examples, however still closing the connection. I am using directly hfClient.loadChannelFromConfig(). There is some issue there that is not easy to see? Should we mount the EH instances manually like in e2e IT?
albert.lacambra (Sun, 28 Oct 2018 15:48:35 GMT):
there is some channel configuration that could produce this connection killing without to show an error/warning to the peer itself?

So do you have any idea what's causing it - is this something that ever happened before? I can provide the two byte array responses if that would help, and can recreate on demand if necessary.

@aatkddny There have been previous reports but in the end when let through the transaction was marked invalid. If you could first do this. Look at SDKUtils.getProposalConsistencySets
It's whats used under the covers. The application can call it too. So try that and verify that it reports more than one consistency set. The send to the orderer turning off the consistency check and see that the transaction is really marked valid

As I tried to say, the response from peer one is 4 bytes longer than the response from peer0. I traced the code over the weekend and since the two payload bytes are different the map in SDKUtils perforce has two values.
The orderer OTOH seems to accept them without issue - or it appears to based on this output.

The one thing I got wrong was versioning. It was all running on 1.3 rather than the 1.2 I stated.
In my defense I didn't expect someone to install the latest version (1.3) into over a perfectly good 1.2 k8s cluster and finding that fact is a pita when you don't have direct access to the images on the server. That notwithstanding it appears that either when instantiating chaincode it is possible to get different responses from peers and have them accepted by the orderer -or- I mucked something up. But if it's the latter I can't see exactly what - my code is unchanged and has worked for a long time.

what does javadoc say about `getPayload` ?

@return binary data set by the chaincode for this event. This may return null.
rickr (Tue, 30 Oct 2018 14:55:53 GMT):
Right -- the SDK has no idea what the data is that the chaincode is setting for the event. Follow the example in End2endIT `EXPECTED_EVENT_DATA` see how the chaincode is sending it.
akoenig (Tue, 30 Oct 2018 14:57:24 GMT):

TLS on fabric vs not on sdk or visa - versa .. just guessing

@rickr Hi, rick, you mentioned that persistence is not part of SDK, here are my two ways to use sdk, one is i save every member user's enrollment cert to my database, the premise is i need to generate keypair in my applications, the other way is i save every member user's userid and password, in this way i need to enroll this user every time when i invoke sdk. Which way is correct. Looking forward to your reply.

@fanjianhang I can't say for certain any specific approach is better not knowing an applications requirements or use cases. That disclaimer said; I don't image I would prefer an approach of continuously enrolling any single user.

adamhardie (Thu, 01 Nov 2018 14:59:45 GMT):
hello, I asked this in a different chat, but wondering if there is a way to solve this using java SDK.
I have a component that connects to HL and subscribes to chaincode events (using a CCEListener implementation).
When i start the appilication I receive a block. This is processed by the application and it updates its state. When I close the app, and start it again, the same block is received. The app has already processed this so actually it overwrites its old saved state. Not a huge issue, but I am wondering if the orderer or SDK is able to know which blocks have already been received by this user and therefore ignore them, without having to save the lastBlockProcessed into a DB or file.
adamhardie (Thu, 01 Nov 2018 15:14:52 GMT):
sorry if it is an obvious answer.. but i cant seem to find details on whether to expect this every time i connect my event listener; is it just by design that the listener receives the most recent block ?
adamhardie (Thu, 01 Nov 2018 15:24:46 GMT):
maybe I can use a custom peer to do this somehow, using PeerOptions? but is it possible without saving the last block processed number

rickr (Thu, 01 Nov 2018 17:24:57 GMT):
@adamhardie That's just default behavior the peer eventing service works ( get newest) . You can specify which block number you want next .. right now it will however block if that block is not there. IMO I would persist which block number that has been successfully processed. As part of defensive programming throw away any block number equal or less than what's been already processed. I would start up asking for that that block to not block(as in wait). Look at getting that block as acknowledgment you're receiving events.
kesavants (Thu, 01 Nov 2018 21:07:27 GMT):
@rickr IMHO I think the eventing service should deliver new blocks created after the service layer has connected. There is also a problem when the grpc connection gets dropped by the the Peer event service redelivers the last block even it was delivered before

akoenig (Fri, 02 Nov 2018 09:19:07 GMT):
Hi, we have a network running with the java-sdk. Now we want to restart the client again, but not the whole network. Anyone got an idea how to solve this? For example we don't want to reacate the channel. We just want that the client finds the channel by himself. But client.getChannel(name) is null because we create a new instance of the client...
akoenig (Fri, 02 Nov 2018 09:22:29 GMT):
or is the only solution to store the channel in the samplestore?
gravity (Fri, 02 Nov 2018 11:24:19 GMT):
hello
is there any way to call system chaincode?
for example, If I want to get a list of channels available for client, can I somehow call `GetChannels` function from `cscc`?
I stuck here, because a channel must be specified when invoke/call chaincode. but which one should I use in this case?

Hey @rickr , I submitted https://gerrit.hyperledger.org/r/#/c/27328/ with only two files changed, PrivateDataIT.java, and the corresponding chaincode used in it: private_data_cc.go
After implementing these changes, I ran PrivateDataIT integration test, which completely passed on my system with the lovely "Thats all folks" message
The hyperledger job builder seems to fail with what looks like an unrelated error saying "Could not find or load main class org.apache.maven.surefire.booter.ForkedBooter"; A file that I didnt even touch. Any pointers? (logs https://logs.hyperledger.org/production/vex-yul-hyp-jenkins-3/fabric-sdk-java-verify-x86_64/2508/console-timestamp.log.gz)

Hi @rickr
is it a correct behavior when a chaincode is being instantiated, the instatiate proposal is sent to three peers (where the chaincode is already installed), but 1 out of 3 peers responds with `SUCCESS`, but 2 out of 3 respond `FAILURE` because they cannot find `lib/cid` ?
it look weird, because peer succeeds with instantiation, but rest of them failed

HI My name is Anil and my company Intain, a member of Hyperledger had issues in using SDK client while trying to interact with chaincode . Our topography uses Google VPC with seperate VM for orderer and peers . We do not get any error but the orderer handshake fails . I have used CLI and it works like a charm but want to use sdk since i have to use process executions and shell scripts , json with cli ...Anybody using the sdk with a enterprise topology , i have used orderer properties, peer properties , channel initialises to true , private key and public key path set , event hub also set for properties just like in the integration test example ..... But orderer handshake fails .... Like i said we are forced to use CLI ....
anilbs (Mon, 05 Nov 2018 05:54:36 GMT):
have anybody used sdk with tls on a enterprise topology ...
rickr (Mon, 05 Nov 2018 14:02:30 GMT):
@anilbs I can't recall for certain anyone has reported success or failure with Google VPC specifically. I do know the sdk is being used with IBM blockchain. What version of the sdk? What jdk ? What version of fabric ? Unrelated but have to ask, why are you still using eventhubs ? Have you tried setting the sdk's log level to trace and looked though it a little .. maybe something you can spot? What actual error are you seeing. Have you set the fabric orderer to debug mode and seen if there was anything at all in it's logs ?

hi all. how do you store enrollment credentials (enrollmentId, enrollmentSecret) for network identities (users) in a safe way? I mean, a scret must be stored safely, because we need it as a plain text to enroll a user on a CA server. the case is, we cannot take a password from the web application and use it for the identity on CA, can we? thanks in advance

No - just that the SDK doesn't do it. Applications certainly can.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=5wtSp7jndcahoqKBW) @gravity Encrypt them before you persist them.
In our case - which suffices because we have a private cloud - passwords go straight into our encrypt routine, enrollments are turned into a hex string using the bouncy castle hex encoder and then encrypted.

aatkddny (Tue, 06 Nov 2018 13:49:53 GMT):
This'll speed things up. There's a pretty good chance I ripped it off from something Rick wrote and it's in the examples anyway, but this will turn an Enrollment into a string and back again.
`enrollmentDetails` is obviously the attribute to be encrypted and is a string.
```
private void saveEnrollmentDetails() throws IOException {
enrollmentDetails = null;
if (enrollment != null) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(enrollment);
oos.flush();
enrollmentDetails = Hex.toHexString(bos.toByteArray());
bos.close();
}
}
private void readEnrollmentDetails() throws IOException, ClassNotFoundException {
if (StringUtils.hasText(enrollmentDetails)) {
byte[] serialized = Hex.decode(enrollmentDetails);
ByteArrayInputStream bis = new ByteArrayInputStream(serialized);
ObjectInputStream ois;
ois = new ObjectInputStream(bis);
enrollment = (Enrollment) ois.readObject();
}
}
```

Hi guys!, I've been exploring the JSDK for fabric for a while and there are few things that still puzzle me. I've gone through most of the tutorials successfully, but exploring a bit further I came across the concept of connections profiles (There are also some issues closed in lira and Gerrit). Initially I thought this would be the way to go in order to provide your application information about the topology of the network that it connects to. However, I have not found any explanation or example on how to use… Additionally, I thought these connection profiles could be also the way to move away from the hardcoded urls that are used in the examples to connect to a CA or a peer… but I might be wrong here. Any idea where can I find more information about it? Many thanks in advanced.

A question about clients, and if this is the wrong channel, please let me know.
I am trying to write a client for a network that contains two organizations, each with two peers. Each network has it's own CA, and there is one orderer. I want to use the client to install chaincode on these peers, however, does each organization have to have its own client? Or is it possible to use a single client to interact with all peers?If each needs it's own, can I install the chaincode on Org1's peers using the CLI and then on Org2's with the client?

Hi all
Is it really necessary to setup mutual TLS? Is it acceptable to go into production with TLS disabled for fabric?
amolpednekar (Wed, 07 Nov 2018 15:36:32 GMT):
You should definitely enable TLS on Fabric network, else this is a major security flaw where all your data being sent will be unencrypted and be susecptible to MITM attacks.
Now mutual TLS is even more secure, since your fabric peers can now verify that the requests are coming from a client that he knows and trusts; requests sent from non-identified client will be immediately rejected. This is a feasible model when you know that there's going to be a controlled number of clients connecting to your peers (B2B apps). If you are distribting your client as mobile apps for say; a consumer application, mutual TLS may not be possible since you need to add each client's certificate to your peer(s)
gravity (Wed, 07 Nov 2018 15:45:57 GMT):
@amolpednekar are there any examples of how to setup client app (fabric java sdk) to use TLS to connect to peers and orderers?
amolpednekar (Wed, 07 Nov 2018 15:54:30 GMT):
This has folder everything you need to get up and running with most SDK basics - https://github.com/hyperledger/fabric-sdk-java/tree/release-1.2/src/test
But just to nudge you in the right direction -
How tls certs are specified in a network config file
https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/fixture/sdkintegration/network_configs/network-config.json#L77-L99
Then use the inbuilt NetworkConfig class to load this file like so:
https://github.com/hyperledger/fabric-sdk-java/blob/release-1.2/src/test/java/org/hyperledger/fabric/sdkintegration/NetworkConfigIT.java

Hi, requesting help. I am trying to build, install chaincode in dev mode (HLF1.3) for java (by following HFL 1.3 documetation for node and trying to translate same things for java). As far as i have understood, we build chaincode in instance of `hyperledger/fabric-ccenv` image and install and instantiate it on channel using `hyperledger/fabric-tools` image named cli. But ccenv image does not have gradle. Am i missing something?
rickr (Sat, 10 Nov 2018 13:47:37 GMT):
@archit90 Would ask #fabric-questions as it's not really specific to JSDK and probably get better luck with larger audience.

@gennadyl I think this really something happening in the Java chaincode execution environment ` java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer`
https://chat.hyperledger.org/channel/fabric-sdk-java?msg=XNQ7qjYqqhmQrMp3q

@gennadyl Besides finding out why it's happening probably should look into why the SDK only gets a timeout instead of something that reflects this error.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=6APWymhsfxtvzTXJA) @rickr This issue is documented here https://jira.hyperledger.org/browse/FAB-12674?workflowName=FAB%3A+Story+Workflow&stepId=2 which is in progress. I managed to solve it by checking out tag `v1.3.0` of https://github.com/hyperledger/fabric-chaincode-java and doing `./gradlew install`
archit90 (Sat, 10 Nov 2018 15:19:09 GMT):
So you will be using `fabric-chaincode-shim:1.3.0` from local maven repo. Hope it helps
archit90 (Sat, 10 Nov 2018 15:19:09 GMT):
Rebuild the chaincode and now you will be using `fabric-chaincode-shim:1.3.0` from local maven repo which is complied using java 8. Hope it helps

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=EJQRciTabCqQsnX3u) Mostly FYI to those who has the question.. This was not really needed in chaincode dev mode.. just build the fat jar and run `java -jar ` in `fabric-ccenv` image
gennadyl (Sat, 10 Nov 2018 16:16:41 GMT):
@rickr will look into it tomorrow

@archit90 odd I've not had to do that and the sdk verification builds are running fine.
archit90 (Sat, 10 Nov 2018 16:45:34 GMT):
@rickr I was facing this while building chaincode. The chaincode builds fine but fails when instantiate is called via cli. Its not for SDK, so agreed this is not correct channel for this.

Previously I read here similar messages and pointers was to add an additional dependencies `netty-tcnative-boringssl-static:2.0.6.final` and `netty-tcnative:2.0.6.final`, but it does not help.
Any advice?
thanks in advance
rickr (Sun, 11 Nov 2018 18:57:13 GMT):
Well 1.3.0-SNAPSHOT pom.xml is referencing 4.1.29.Final . IMO would look what's there and what's seems to be _playing nice together_ and stick to that.

I experience the same issue if I start a cli container and attempt to create/join the channel and install/instantiate the chaincode manually, without any java client.
gravity (Tue, 13 Nov 2018 11:20:17 GMT):
hi all
are there any use cases for generating CRL? As I can see from the SDK, it is possible to revoke a certificate without generating a CRL, but the documentations says next:
```
After a certificate is revoked in the Fabric CA server, the appropriate MSPs in Hyperledger Fabric must also be updated. This includes both local MSPs of the peers as well as MSPs in the appropriate channel configuration blocks.
```

@SudeepS 2 Yea, the End2End test will do all of that for you. The certificates and stuff have already been generated and are in the `fixture` folder.

Hi. Question about Service Discovery.
I'm currently using

3) try to mimic example (ServiceDiscoveryIT)

Hi. Question about Service Discovery.
I'm currently using
1) First Network as my network settings(but I kill org2 peers, so left with two org1 peers)
2) putting only one peer on network-config.yaml (peer1.org1.example.com)
3) try to mimic example (ServiceDiscoveryIT)
For initial discovery Peer:
Properties property =new Properties();
property.put("pemFile", "./network/fabric-samples-1.2/first-network/crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem");
property.put("ssl-target-name-override", "peer0.org1.example.com");
property.put("hostnameOverride", "peer0.org1.example.com:7051");
Peer dP = client.newPeer("peer0.org1.example.com", "grpcs://localhost:7051", property);
For rest of discovery:
sdProp.put("clientCertFile", "./network/fabric-samples-1.2/first-network/crypto-config/peerOrganizations/org1.example.com/users/User1@org1.example.com/tls/client.crt");
sdProp.put("clientKeyFile", "./network/fabric-samples-1.2/first-network/crypto-config/peerOrganizations/org1.example.com/users/User1@org1.example.com/tls/client.key");
sdProp.put("pemFile", "./network/fabric-samples-1.2/first-network/crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem");

Failed endpoint grpcs://localhost:594 to parse certificate TLS client
rickr (Tue, 13 Nov 2018 14:30:39 GMT):
@gravity Most likely your TLS certificates were signed by the wrong CA.
rickr (Tue, 13 Nov 2018 14:33:21 GMT):
@kisna I think the SDK is deploying Java chaincode just fine. The integration test which are passing are working just fine and they install and invoke chaincode. I think you'd get better audience with #fabric-chaincode-dev or #fabric-java-chaincode channel.
rickr (Tue, 13 Nov 2018 14:33:44 GMT):
@AishwaryaKudalkar channel.getPeers does give ALL channels.

gravity (Tue, 13 Nov 2018 14:34:20 GMT):
@rickr
and there is one more question about `revoke` method
one of the overrided methods has boolean `genCrl` parameter. if a method is called with `genCRL=true`, will the update channel config transaction be generated and sent to an orderer under the hood?
rickr (Tue, 13 Nov 2018 14:38:02 GMT):
@gravity did you not cross post that on the #fabric-ca channel? ... if yes, please don't do that
gravity (Tue, 13 Nov 2018 14:39:15 GMT):
yes, I did
excuse me if went wrong
rickr (Tue, 13 Nov 2018 14:41:59 GMT):
@tballast `ERRO 002 context deadline exceeded` maybe better of #fabric-peer-endorser-committer channel.
gravity (Tue, 13 Nov 2018 14:47:30 GMT):
@rickr
could you give me a clue about the `genCRL` parameter?
adamhardie (Tue, 13 Nov 2018 15:22:21 GMT):
when a chaincode call fails, my code prints the following
SEVERE: verify: Cannot retrieve peer identity from ProposalResponse. Error is: X.509 not found
adamhardie (Tue, 13 Nov 2018 15:23:21 GMT):
is there a way to handle this more gracefully? Eg i have a query function that looks up a key based on getCreator. If they have no value saved, i am receiving this errored proposal
adamhardie (Tue, 13 Nov 2018 15:24:05 GMT):
(NB if the user key exists the chaincode returns the expected value associated with the key so it is working otherwise)
adamhardie (Tue, 13 Nov 2018 15:45:15 GMT):
Part2 : some questions about PeerOptions
it seems quite random on whether the peer receives the latest block or not when subscribing to chaincode events
I have set options.StartEvent(0L) in peer options when adding to channel. however i am not receiving any blocks
adamhardie (Tue, 13 Nov 2018 15:45:28 GMT):
is 0L the genesis block? what should i do if i want to load the full chain from start
adamhardie (Tue, 13 Nov 2018 15:45:31 GMT):
thanks
aatkddny (Tue, 13 Nov 2018 18:59:29 GMT):
so i'll admit i haven't spent very long looking at it, but I'm struggling to figure out what's supposed to be in the zip if you want to run java chaincode. I expected you'd stream in a built jar, but it doesn't look like that's the case.
rickr (Tue, 13 Nov 2018 19:31:57 GMT):
@adamhardie What version of the SDK are you running? This sounds like something that was addressed.
rickr (Tue, 13 Nov 2018 19:59:54 GMT):
@chill37 I'm thinking your fabric is running in docker where does addressees resolve, but on the native vm they don't
rickr (Tue, 13 Nov 2018 19:59:54 GMT):
@chill37 I'm thinking your fabric is running in docker where those addressees resolve, but on the native vm they don't
chill37 (Wed, 14 Nov 2018 00:35:46 GMT):
@rickr yes. fabric is running in docker. is there a way to resolve this? I'm not sure how to change the 'Discovered Nodes' to have the same address type(grpc:localhost) . thanks!
AishwaryaKudalkar (Wed, 14 Nov 2018 04:17:05 GMT):
@rickr I was running the integration test for Network Config(NetworkConfigIT.java) in debug mode and channel.getPeers() was returning peers belonging to the usercontext set (say, Org1). And that should be the case otherwise you get the following error.

looks better - thanks @rickr
I am now storing last block processed on the ledger per user, and loading that at startup, then the peer listens from that block. Thank you for your guidance so far
one question - When i connect my Chaincode event listener, with PeerOptions.startEvents(100) eg, and there are 10 blocks.
It seems the listener reads from 100, but in a random order. Eg 105, 104, 109. Should the orderer not guarantee the order of receipt here

Maybe that doesn't fix it up .. have relook later .. it's either that or Networkconfig is not using v1.1 paths .. I think it only uses one channel

rickr (Wed, 14 Nov 2018 15:03:39 GMT):
no. If you are running the provided integration tests they don't reference port 594.
rickr (Wed, 14 Nov 2018 15:03:39 GMT):
no. If you are running the provided integration tests they don't reference port 594. Probably, just what the error is stating the private TLS key being provided does not parse.
rickr (Wed, 14 Nov 2018 15:33:30 GMT):
@SudeepS 2 You are right that the network-config-tls.yaml references for peer1.org1 a tlsCACerts path to v1.1 However, if you compare v1.1 with v1.3 they're the same. I don't think we reran cryptogen again for 1.3. So something that should be addressed and the network-configs should be updated when going to a new release - in the short term there's now harm being done.

gravity (Wed, 14 Nov 2018 15:58:00 GMT):
According to the example provided here
https://github.com/hyperledger/fabric-sdk-java/blob/release-1.2/src/test/java/org/hyperledger/fabric/sdk/testutils/TestConfig.java#L299
we need user certificates to use them as `clientCert` and `clientKey` to connect to an orderer and peers
at this example, an orderer is configured using Admin certificate and peers are configured using a common user's certificates.
is it done in that way in sake of simplicity of the example? or we actually should use the same certificates (an admin for orderer and a user for peers) in a production environment?
chill37 (Wed, 14 Nov 2018 16:12:32 GMT):

@gravity As long as your tls client key is signed by a tls ca cert in the certificate chain I don't see why it wouldn't work. Don't confuse TLS certs with proposal and transaction signing and verification certs.

@rickr Actually it works as expected

Hello, I've an interesting question. I'm trying private data collection and I have created a collection1 for Org1MSP. Then I've created a user for Org2MSP and send a query operation to peer0.org1 to read collection1 asset. I was expecting that the user shouldnt be able to read collection1 asset because only Org1MSP should reach this data. However it could return the data. I have debugged and cid.getmspid also returns Org2MSP. Private data collections only look for peer msp or am I missing some point the way it works?

How to register for events
Registration for events from either service is done by sending an envelope containing a deliver seek info message to the peer that contains the desired start and stop positions, the seek behavior (block until ready or fail if not ready). There are helper variables SeekOldest and SeekNewest
is this available from the SDK? in registerChaincodeEventListener i cannot see any options for this
(from https://hyperledger-fabric.readthedocs.io/en/release-1.3/peer_event_services.html )
adamhardie (Thu, 15 Nov 2018 13:30:16 GMT):
seems that this would be great for me as not all blocks have the events i am listening for; therefore i am currently replaying up to blockchain height. but if the latest block has no event it is hanging.
adamhardie (Thu, 15 Nov 2018 13:30:41 GMT):
if i could use seekNewest to find the newest block, I will know when the replay queue is complete and can start reading in order

@halilkalkan For an explanation see the doc at: https://hyperledger-fabric.readthedocs.io/en/latest/private-data-arch.html
dave.enyeart (Thu, 15 Nov 2018 14:44:04 GMT):
this bullet:
dave.enyeart (Thu, 15 Nov 2018 14:44:07 GMT):
```Note that private data collections only define which organization’s peers are authorized to receive and store private data, and consequently implies which peers can be used to query private data. Private data collections do not by themselves limit access control within chaincode. For example if non-authorized clients are able to invoke chaincode on peers that have access to the private data, the chaincode logic still needs a means to enforce access control as usual, for example by calling the GetCreator() chaincode API or using the client identity chaincode library .```
dave.enyeart (Thu, 15 Nov 2018 14:45:00 GMT):
In an upcoming release an option will be added to have the chaincode automatically enforce the access control, see: https://jira.hyperledger.org/browse/FAB-11409

@knagware9 You can't run a peer on android, but perhaps a client app based on java sdk. Any thoughts @rickr

rickr (Thu, 15 Nov 2018 15:50:50 GMT):
@knagware9 In my personal opinion I don't see value running sdk on mobil (android). I think it's to heavy for that. Design your mobile app (Android and iphone) for what it does best, the user experience. Have it's own API to a server that runs a hyperledger SDK.
halilkalkan (Thu, 15 Nov 2018 15:52:59 GMT):
@rickr @dave.enyeart Thank you for your explanations. Actually, I asked the question on SDK side because I'm invoking the chaincode with Java SDK. So as far as I understand, private data collection only looks for which peer the chaincode invoked rather than client user context. In my case, I was setting client user context as a user from Org2MSP but because I'm sending only Org1MSP's peer the private data could be visible.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=LTdiDWxHLBWHA4EKt) @rickr with your advice, I tried the following:
127.0.0.1 peer0.org1.example.com
127.0.0.1 peer1.org1.example.com
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
=> THEN it works (UnknownHostException NOT occurred)
Now, it seems that 'hostnameOverride' property should be doing this exact thing
(From EXAMPLE) sdprops.put("org.hyperledger.fabric.sdk.discovery.endpoint.hostnameOverride.localhost:7056", "peer1.org1.example.com");
but, when I try this method, (and without changing /etc/hosts) I still get UnknownHostException.
is that property setting grammar correct?

how do i make that a peer leaves a channel?
giacomo.minighin (Mon, 26 Nov 2018 13:55:58 GMT):
is there any channel creation envelope class or channel update envelope class?

Is there a channel for queries on blockchain explorer?
BhavathiReddy1 (Tue, 27 Nov 2018 11:07:08 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=GDjpPm2yHtAJft6qg) @giacomo.minighin Yes. There is an UpdateChannelConfiguration class which along with getUpdateChannelConfiguration can be used to update the channel configuration. But you need to calculate the delta of the old and new configs first as mentioned in the docs. I have a sample code for the same (adding an org called acropolis). Hope it helps:
BhavathiReddy1 (Tue, 27 Nov 2018 11:07:29 GMT):
ChannelUpdateScript
Generate crypto keys and configuration for new org:
~/fabric-samples/bin/cryptogen generate --config=./crypto-acropolis.yaml
~/fabric-samples/bin/configtxgen -printOrg AcropolisMSP > ./acropolis.json
Log into existing peer:
docker exec -it peer0.idp.nutanix.com bash
peer channel fetch config config_block.pb -o 10.142.0.12:7050 -c mychannel
exit
Copy channel config and calculate difference:
docker cp peer0.idp.nutanix.com:/opt/gopath/src/github.com/hyperledger/fabric/config_block.pb ./
~/fabric-samples/configtxlator proto_decode --input config_block.pb --type common.Block | jq .data.data[0].payload.data.config > config.json
jq -s '.[0] * {"channel_group":{"groups":{"Application":{"groups": {“AcropolisMSP":.[1]}}}}}' config.json acropolis.json > modified_config.json
~/fabric-samples/configtxlator proto_encode --input config.json --type common.Config --output config.pb
~/fabric-samples/configtxlator proto_encode --input modified_config.json --type common.Config --output modified_config.pb
~/fabric-samples/configtxlator compute_update --channel_id mychannel --original config.pb --updated modified_config.pb --output acropolis_update.pb

rickr (Tue, 27 Nov 2018 14:44:56 GMT):
@AishwaryaKudalkar Well your using service discover peer and it says peer1.org1.example.com but guessing that does not resolve for you.
rickr (Tue, 27 Nov 2018 14:45:42 GMT):
@amolpednekar you would only ever join _your own_ peer once to the channel then after if you reconstruct just add it.
rickr (Tue, 27 Nov 2018 14:46:03 GMT):
@gennadyl all direct dependencies are in the pom.xml
rickr (Tue, 27 Nov 2018 14:47:04 GMT):
@gravity The sdk does not care about any particular file name. The name is generated by crypotgen.
rickr (Tue, 27 Nov 2018 14:50:20 GMT):
@Randyshu2018 Not sure what you mean by _customer event_. The SDK has a means to register for all block events and specific chaincode events.

@rickr maybe I'm missing something:
i'm loading the network configuration from NetworkConfig like this:
```
NetworkConfig network = NetworkConfig.fromYamlFile(new File(configPath));
for (String chName : network.getChannelNames()) {
Channel channel = client.loadChannelFromConfig(chName, network);
channel.initialize();
}
```
the error happens when I initialize the channel.
My network configuration has 2 peers, one for organization that are also anchors peers:
```
peer0.org1.example.com:
url: grpc://localhost:7051
eventUrl: grpc://localhost:7053
grpcOptions:
ssl-target-name-override: peer0.org1.example.com
tlsCACerts:
path: ../devenv/network/network/channel/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

my vagrantfile is ok

if you're using tls wouldn't the url protocol be grpcs ?

I am able to add and update the chaincode

but I am having 2 issues
umershabbir (Wed, 28 Nov 2018 21:31:18 GMT):
1. when I switch the user from org1 to org2 to query the chaincode it require multiple retries the switch the user from org1 user1 to org2 user2 but eventually after few retries it successfully switches the user
umershabbir (Wed, 28 Nov 2018 21:32:13 GMT):
2. I want to include a private dataset in the chaincode in such a way that only org1 users should be able to query/update that private data but not org2 users.

Hi @rickr
As long as I can see, JSDK does not support the structure of a collection config that is documented here:
https://hyperledger-fabric.readthedocs.io/en/release-1.3/private_data_tutorial.html#build-a-collection-definition-json-file
hence the structure of the config should be like this yaml even if it passed as a JsonArray?
https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/fixture/collectionProperties/PrivateDataIT.yaml
rickr (Thu, 29 Nov 2018 14:01:40 GMT):

The sample used yaml as I tried to put some simple comments in it which Json does not allow.
rickr (Thu, 29 Nov 2018 14:06:48 GMT):
@giacomo.minighin That's right as the javadoc states it's the *raw* block . That's protobuf nothing to do with Json.
rickr (Thu, 29 Nov 2018 14:15:09 GMT):

rickr (Thu, 29 Nov 2018 22:46:47 GMT):
no -- it shows defining and using private data.
rickr (Thu, 29 Nov 2018 23:03:15 GMT):
@umershabbir if you're looking to setup up a channel used by two orgs this would help. But its a bit _fake_ having two orgs in the same application -- it's just for demonstration purposes. I think it would be a combination of the PrivateDataIT I refereed to and this. https://github.com/cr22rc/fabricSDKJavaMultiDomainSample

rickr (Fri, 30 Nov 2018 16:53:41 GMT):
The PrivateDataIT has a sample yaml file. It also invokes a GO chaincode that uses private data APIs. You need to ask on #fabric-java-chaincode for where they've documented their Java CC APIs I'm _guessing_ it has at least Javadoc.
AndresMartinezMelgar.itcl (Mon, 03 Dec 2018 09:46:16 GMT):

rickr (Mon, 03 Dec 2018 13:05:14 GMT):
@AndresMartinezMelgar.itcl The JSDK has the simple balance transfer. No specific SDK should really care about the chaincode it deploys and executes. A better place for chaincode questions would be #fabric-chaincode-dev or #fabric-java-chaincode .
rickr (Mon, 03 Dec 2018 13:12:09 GMT):
@halilkalkan The SDK has `user contexts` This is a combination of MSP ID, usually some sort of certificate, and private/public key pair. If you were embed the SDK in some other technology like Spring or HTTP/Web _session_ that corresponded with a user, your application would most likely I think need to map that _session_ with a specific user context.

The next step was to use our java client to connect to org1 and enrol some users (admin, newco-admin, test) which worked after some updates on our code to use Java SDK for Hyperledger version 1.2.1 instead of 1.1.0-alpha.
However, when trying to submit transactions to the "platform" channel that had the profile chaincode installed and running, we encountered errors such as:
"19:44:37.858 [ERROR] o.h.f.s.Channel:1772 - getConfigBlock for channel platform failed with peer org1-peer1. Status FAILURE, details: Sending proposal to org1-peer1 failed because of: gRPC failure=Status{code=UNIMPLEMENTED, description=HTTP status code 404

@rickr Does Java SDK support V1.2.1? where should I start with the error like above?

Hi everyone. I want to use Idemix so I am trying to run the integration test of fabric-sdk-java/master branch. However, I received the following errors during the run of the IT and failed at last:
- "org.hyperledger.fabric_ca.sdk.exception.EnrollmentException: Failed to get Idemix credential", and
- "Invalid nonce: Nonce is either unknown or has expired".
Does anyone know how to fix these errors or what the root cause of these errors is?
I use the following tools:
openjdk version "1.8.0_181"

@rickr Where exactly can i find the file on the peer that contains the transaction information. How is the SDK able to find the file given the transaction id.
Could you point me to the class where the SDK searches for the transaction file and reads it .
rickr (Wed, 05 Dec 2018 14:25:35 GMT):
@ApurvTandon I'm not aware of any _file_ for a transaction.
rickr (Wed, 05 Dec 2018 14:30:05 GMT):
@SandySun2000 Any SDK greater than 1.2 version should. You need to look at the peer logs. Some things to check: Are you using the correct channel name? Was that peer joined to the channel ?
ApurvTandon (Wed, 05 Dec 2018 15:07:28 GMT):
@rickr where on the system are the transaction and all information of the transactions stored
rickr (Wed, 05 Dec 2018 15:18:17 GMT):
On the ledger

@rickr ok can we see the transaction data on the ledger like under some location on the system ?
ryokawajp (Wed, 05 Dec 2018 16:23:19 GMT):
I retried the integration test with the source code which has v1.3.0 tag and I got the same error.
This time I did not need to modify pom.xml.
I just executed "mvn clean install -DskipITs=false -Dmaven.test.failure.ignore=false javadoc:javadoc" and the error was displayed about two hours later.
Any suggestions?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=3CmLW8bXF6gx3pm8J) @rickr Thanks Rick, I will look for more detail information for this issue.
rickr (Wed, 05 Dec 2018 17:36:47 GMT):
@gravity I'm running a network v1.3.0 and java sdk v1.2.2 why?
gravity (Wed, 05 Dec 2018 17:37:56 GMT):
@rickr Because I have not upgraded yet jsdk to 1.3.0. just today noticed that it was released
rickr (Wed, 05 Dec 2018 17:38:42 GMT):
you should have been running with 1.3-SNAPSHOT if you were using 1.3 fabric ..
gravity (Wed, 05 Dec 2018 17:39:51 GMT):
so that issue might be connected to the sdk version mismatch with the network version?
rickr (Wed, 05 Dec 2018 17:40:21 GMT):
I don't know -- but it's something we don't test ever
gravity (Wed, 05 Dec 2018 17:41:12 GMT):
ok, I will run the same flow with the jsdk v1.3.0 and check if the exception is thrown
ryokawajp (Thu, 06 Dec 2018 01:52:12 GMT):
Thank you, @rickr . I will retry the test with more CPUs or with a different JVM (Oracle or IBM).
ApurvTandon (Thu, 06 Dec 2018 03:39:51 GMT):
@rickr actually i was looking for the transaction and where on the system they are stored, like a location on the ubuntu machine, i wanted to see what kind of information is stored in the file or however they are stored
ryokawajp (Thu, 06 Dec 2018 03:41:14 GMT):
@rickr Thank you for the information.
I retried the integration test with IBM JDK and it successfully finished in 14 mins.
(After that, I got errors when generating javadocs, though.)
Therefore, you are right; the error was caused by a timeout. The following list shows times required to execute the IT with various JDKs.
- Open JDK 8: 2 hours (failed due to the nonce error during testGetIdemixCred ).
- Oracle JDK 8: 2 hours (failed due to the nonce error during testGetIdemixCred ).
- IBM JDK 8: 14 minutes (success).
I also observed that during the unit tests, it takes a considerable time (10-20 mins) to complete org.hyperledger.fabric.sdk.identity.IdemixIdentitiesTest if I use OpenJDK or Oracle JDK, while it takes a few seconds to complete it if I use IBM JDK.
I used Ubuntu 16.04 VM (on Virtual Box on Windows 7) with 2 cores and 8GB memory assigned for all the three cases.

adamhardie (Thu, 06 Dec 2018 12:40:02 GMT):
could someone please help me mitigate this risk from a production system :
""ChaincodeEventListener should not be long lived as they can take up thread resources""
adamhardie (Thu, 06 Dec 2018 12:41:09 GMT):
should we shutdown the listener impl periodically? or just monitor resources. we just hit a OutOfMemory exception in our test server
SEVERE: Error calling block listener BLOCK_LISTENER_HANDLE {logging stuff}
java.lang.OutOfMemoryError: unable to create new native thread
rickr (Thu, 06 Dec 2018 13:03:04 GMT):
@adamhardie I've had over 400 threads running for 8 hours creating proposals, sending transactions doing queries etc. All threads working independently against the same chaincode . I also monitored with independent jvmconsole that threads and memory leveled off as all the resources needed for them were meet. Generally, I don't see the SDK itself leaking any memory/threads. There's one scenario just brought to my attention where if the application constantly create channels/ shutsdown it leaks one thread - but I don't think applications would see that as a typical use case. The fix for that will be in the next release.
rickr (Thu, 06 Dec 2018 13:04:56 GMT):
@ApurvTandon if your trying to understand the internal workings of the Peer, I'd suggest the #fabric-peer-endorser-committer channel.
adamhardie (Thu, 06 Dec 2018 13:05:11 GMT):
thanks for clarifying - will continue my investigation
rickr (Thu, 06 Dec 2018 13:13:19 GMT):
@adamhardie You should be careful what you do in your handlers too. They should be _short lived_. Process the block information needed .. store somewhere and then return back.
adamhardie (Thu, 06 Dec 2018 13:15:36 GMT):
agreed- we merely deserialize the json, with some of the block report info; then add to a queue to be picked up by another thread

hi all
I'm running a network v1.3.0, jsdk v1.3.0
trying to set up service discovery, but stuck with the tls handshake error:

this error occurs when `channel.initialize` is called

`peer0CrtBytes` and `peer0KeyBytes` are the same certificate that are used in peer's properties.
aatkddny (Thu, 06 Dec 2018 15:02:46 GMT):
so we had a failure yesterday where a peer was evicted. when we bring it back up it won't process updates, despite them being physically on the disk for that ledger and visible in the couch db disk.
Any connection to the peer starts throwing these errors:
```Received error on peer eventing service on channel xx-xx-channel, peer xx-peer1-yy, url grpc://st-mofabric-demo02.na.rtdom.net:30031, attempts 1. UNAVAILABLE: Channel shutdownNow invoked```
I just reinstantiated this connection. The ones in the cluster are in the 10s of thousand.
Is there a way to fix this without restarting everything?

aatkddny (Thu, 06 Dec 2018 15:02:46 GMT):
so we had a failure on our cluster yesterday where a kafka and a peer were evicted. when we bring them back up it now won't process updates on one of the channels.
For clarity, the update adds - and I can see it physically on the disk for that ledger and visible in the couch db disk, but I can't read it.
Any connection to the peer starts throwing these errors:
```Received error on peer eventing service on channel xx-xx-channel, peer xx-peer1-yy, url grpc://st-mofabric-demo02.na.rtdom.net:30031, attempts 1. UNAVAILABLE: Channel shutdownNow invoked```
I just reinstantiated this connection. The error counts in the service that contacts the peers in the cluster are in the 10s of thousand - it's been running since it too was restarted yesterday.

rickr (Thu, 06 Dec 2018 15:45:43 GMT):
@aatkddny you can adjust the error warning rate by upping PEER_EVENT_RECONNECTION_WARNING_RATE see Config.java .. but not without restarting.
Not sure I follow _won't process updates_ do you mean your not getting and events ? Is the peer eventing service never connecting ?
The other error x.509 not found .. what's happening here ? Is that getting an endorsement ? The peer is no longer processing endorsements ?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=aSMed39qkzQd3Z4qo) @rickr It's a bit abstruse. I add an asset. It says it's fine. I can see it physically on the disk - i look at a hex dump of the ledger and the couch and can see my asset in the rest of it on the peers that are misbehaving.
BUT when I go to read it nothing comes back.
The only errors I can see are those eventing ones.
I'm clutching at straws - is there something in the eventing (and this is a holdover from 1.1) that the eventhub needs to serve before a transaction commits? And if so how would I "fix" it here.

When I go to try to read all the blocks in the channel the asset was added on - using a copy of the block-walker from the examples - it gives me that x509 error, but there's no new crypto generated for this thing.
rickr (Thu, 06 Dec 2018 15:59:39 GMT):
Nothing with peer eventing service or old eventhubs have anything to do with blocks actually committing. They tell the client when they're committed.

When you `read it` is that using queryBlockByNumber ?

If I have a channel setup with out event hubs and peers without `EVENT_SOURCE` role, how transactions will complete when I call `HFClient.sendTransaction(proposals)`?
Does the future that is returned from the `sendTransaction` indicate (when complented) that the transaction was not only queued on the orderer, but it was actually committed to the blockchain?
rickr (Thu, 06 Dec 2018 18:11:39 GMT):
As the end2end test shows when the future is complected the queried results are written to the block
gravity (Thu, 06 Dec 2018 18:13:42 GMT):
but if event hubs are configured and peers were joined/added to a channel with the role `EVENT_SOURCE`, then the future doesn't indicate that that the transaction was commited, right?

Any plans to validate builds using Corretto? Yeah yeah openJDK - of course there will be no incompatibilities so openJDK will suffice (garbage collection cough cough).
The pricing and their commitment to LTS means we are looking long and hard at it is why I'm asking.

ok, will try
btw, is there any way to check that channel already exists? for example, I created a channel, but didn't join peers into it. just an empty channel. in this case, I want to check if channel exists and if not - create it, if it does exists - join peers into that channel.
this can be helpful in case of setup failure. for example, I created a channel, but the application went down and join request failed. and on the next start up, I want to join peers to the channel that was created before failure

ryokawajp (Fri, 07 Dec 2018 14:40:25 GMT):
I measured the time of the unit test of v1.3.0 by running "mvn install" command on a various environments.
Fast?=TRUE means that the UT is completed within 2 minutes and Fast?=FALSE means that it takes more than 10 minutes.
In the latter case, most of the time is consumed in IdemixIdentitiesTest and the CPU utilization is almost zero at that time.
I think I can say that:
- CPU (Xeon or Core i5) does not matter.
- IBM JDK is always OK in any environment.
- Assuming that Oracle JDK and Open JDK are compatible, those JDKs work fine on Windows (native) but not on Linux VMs.
- I could not identify whether a use of VM has something to do or not because I do not have a Linux native machine.
The result could be inconsistent with the situation on @rickr 's build environment.
The result is very complicated ...:expressionless:
Unfortunately, I do not have a means to further investigate this issue, so I would like to use IBM Java as a workaround.
If someone else also experiences this phenomenon, then I am happy to create a JIRA issue and share this result.

1. for mutual tls can i use the keys generated by fabric CA?
2. just to verify, mutual tls is used between fabric client(ex. application with fabric-java-sdk) to peer or orderer right?
ryokawajp (Mon, 10 Dec 2018 06:36:50 GMT):
Thank you, @rickr .
I think I understood what happened to my systems. In a Linux system, there two random number generators:
- /dev/urandom: non-blocking but less secure.
- /dev/random: blocking but secure.
In the latter case, the initialization of the random number generator used in SecureRandom in Java "consumes" the system's entropy and might be blocked if the entropy is exhausted. Then SecureRandom waits for a system to recover the entropy by influences from external I/O devices.
As you suggested, VMs have less entropy and that is why the UTs took a long time except for the first time. If the hardware supports RNG, then one can install rng-tools and run rngd to increase the system's entropy. Recent CPUs after ivy Bridge have CPU-level RNG supports but my old Xeon machine doesn't have.
The reason why IBM Java works faster than Open JDK is that the default RNG is set to /dev/urandom, which is less secure. This can be configured in securerandom.source parameter in $JAVA_HOME/jre/lib/security/java.security
https://blogs.oracle.com/java-platform-group/thats-so-securerandom
http://giovannitorres.me/increasing-entropy-on-virtual-machines.html
ryokawajp (Mon, 10 Dec 2018 06:38:58 GMT):
Now, I installed rng-tools and executed rngd on a Linux VM on a Core i5 machine and everything is fine including IdemixIdentityTest in the unit test even in the case of Oracle JDK 8 and Open JDK 8.

@anjalinaik getting it signed by two orgs is simply send it to the two organizations orgs peers then send the signed endorsements to the orderer.
https://github.com/cr22rc/fabricSDKJavaMultiDomainSample
That shows if you follow the comments closely forcing the signing to two orgs.

hi all
are there any drawbacks in serializing channels, storing in db and deserializing them later for use?
rickr (Mon, 10 Dec 2018 16:03:22 GMT):
@giacomo.minighin I think that code walks through getting information from BlockInfo. Not helpful ?
rickr (Mon, 10 Dec 2018 16:08:56 GMT):
@gravity I would at what information you need to restore a channel in the End2endAndBackAgainIT Decided how you want the schema for your database to look like to store those artifacts. Table of Peers, Orderers with name, url, a key channel etc, Table channels, name etc.
gravity (Mon, 10 Dec 2018 16:24:51 GMT):
@rickr for example, if I have a table Channels and I want to store there channel's representation in byte + some meta info, so then I will be able to grab channel bytes from a database, deserialize, initialize and use it.
but there is one question: if I shutdown an application so the HFClient instance, that previously held the information about a channel, is destroyed and on the next startup I will deserialize a channel from bytes, will this channel object have the information about peers and orderers that were added to this channel?
or should I call `addPeer` and `addOrderer` methods to add the necessary information to a channel?
rickr (Mon, 10 Dec 2018 16:29:26 GMT):
@gravity Look at the End2endxxxxIT test they do this. Be advised that when the SDK goes to different versions there's no upgrade provided for any java serialization. I you do use that, it's something you'll have to take on. IMO I would not use that. Store what you need in your own application format.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=Xvz57RMMNXg2qFJZo) @ShobhitSrivastava exactly my point..in my understanding if one of the couchdb is tampered, then none of the transactions should occur. But its the other way around
ShobhitSrivastava (Wed, 12 Dec 2018 11:09:53 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=9iqPSe2QGDTRGRp4Y) @anjalinaik yes, you are right. Ideally what everyone thinks that if you delete one entry in a block all there will not be any new transaction as previous block has got corrupted
ShobhitSrivastava (Wed, 12 Dec 2018 11:11:27 GMT):
but deleting txns from UI does not delete the txns from block. If you clear the data directory of couch of a peer. And restart the peer and couch. Those entries will again come.
anjalinaik (Wed, 12 Dec 2018 11:14:12 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=CzQ9zftksa37poWqQ) @ShobhitSrivastava the last point which you made is putting the peer down and then bringing it back again and joining the channel, therefore it retireves blocks from other peers, correct?
anjalinaik (Wed, 12 Dec 2018 11:18:02 GMT):
so , if we have to prove tamper proof ability of fabric , how do we do it?
ShobhitSrivastava (Wed, 12 Dec 2018 11:29:56 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=Xxne4byEjkZzjiLaF) @anjalinaik I think it fetches from all the peers joined on a channel(from knowledge of gossip protocol). Measures to run ledger in restricted environment and at no cost reaveal this UI of couch. Then without endorsement deleting a data or modifying is not possible. For more details may be @rick or @dave.enyeart can provide more update.Thanks
ShobhitSrivastava (Wed, 12 Dec 2018 11:40:14 GMT):
Hey @anjalinaik . I found the same ques I asked 2 months back. Please find the @dave.enyeart answer as below " dave.enyeart October 24, 2018 3:38 PM
Clients send proposals to multiple peers and check consistency of results. If one peer doesn't match, clients won't trust that peer anymore and will not go to it anymore. Doing a verification of entire chain for each transaction is prohibitively expensive. You can do a verification of peer's blockchain using external tools instead. Think of statedb as a cache. If it's data is in doubt you can drop statedb and it will be rebuilt from the blockchain automatically upon peer restart. But I'd recommend lock down couchdb by not exposing couchdb port beyond the peer's docker network and have peer use username/password to ensure it cannot be tampered by external users in the first place."

Hello, I'm trying to connect to java sdk to a 1.3 fabric network but im stuck on the eventhub and keep getting the following error:
`2018-12-12 13:37:17.920 WARN 26841 --- [ault-executor-0] org.hyperledger.fabric.sdk.EventHub : EventHub{id: 2, name: eventhub01, channelName: mychannel, url: grpc://localhost:7053} terminated is false shutdown is false, retry count 351 has error UNAVAILABLE: Network closed for unknown reason.`
If I check how I did it in NodeJS I notice that you need to add the eventhub to the peer ( eventhub = channel.newChannelEventHub(peer) ), how can I do this in Java?
aatkddny (Wed, 12 Dec 2018 13:44:46 GMT):
isn't the eventhub deprecated in 1.3?

aatkddny (Wed, 12 Dec 2018 13:56:12 GMT):
Well my code's not as new as it could be, but I do this: `channel = client.loadChannelFromConfig(name, org.getNetworkConfig());` where `org.getNetworkConfig()` returns a cached `org.hyperledger.fabric.sdk.NetworkConfig`
aatkddny (Wed, 12 Dec 2018 13:56:12 GMT):
Well my code's not as new as it could be, but I do this: `channel = client.loadChannelFromConfig(name, org.getNetworkConfig());` where `org.getNetworkConfig()` returns a cached `org.hyperledger.fabric.sdk.NetworkConfig` that in one case I build myself from saved channel definition information and in the other I pull from the cloud provider that's hosting the network. Saved duplication and simplified vs manually joining all the peers and all that good stuff.

rickr (Wed, 12 Dec 2018 14:35:15 GMT):
@doyajii1 no way to unregistered multiple blockhandlers .. I wonder why you need to have more than one. I don't understand your second question. You get a blockevent from the Peer for each block that is committed to the channel.
rickr (Wed, 12 Dec 2018 14:38:18 GMT):
@AndresMartinezMelgar.itcl look for blockWalker in End2endIT.java for traversing the blocks in the ledger
rickr (Wed, 12 Dec 2018 14:42:18 GMT):
@Aschi EventHubs are gone in Fabric1.3 They're replaced by PeerEventingSevice see PeerRole .EVENT_SOURCE role when add a peer to a channel to get events in almost the very same way as with eventhubs.

In the cli enrollment is a one-line command involving just the ca's url, a username and a password.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=PavzBMciYHzfCdbTP) @rickr Thanks for the tip, but this test involves a very large number of different classes and files, and (from my current understanding) requires setting up config files as well as actual nodes on the network. Before moving on to that I would like to test smaller pieces of code with just the CA running.
In the cli, enrollment can be as simple as a one-line command involving the ca's url, a username and a password.

Edit: Never mind, my previous error seems to have been caused by me trying to fit the enrollment into an array, then print it.
However, I am still facing this error: ```org.hyperledger.fabric_ca.sdk.exception.EnrollmentException: Failed to get Idemix credential

Caused by: org.hyperledger.fabric_ca.sdk.exception.HTTPException: POST request to http://192.168.18.57:7054 failed request body {"request":null}. Response: 404 page not found

The X509 enrollment succeeds, so I'm sure the CA URL and connection is correct. I can see the x509 enrollment showing up in my CA's log but nothing shows up about the idemix enrollment.

Hi @rick. I was using the multi org endorsement code from your github link. But one issue in that is it only works if the creator of channel suppose Org1Msp is the request client and needs endorsement for peers from its own and peers from other organisation However if I do it otherwise like send a request from Org2Msp for endorsement to Org1 peer, it gives access denied issue. How will this thing work in production, as there would be possibility of twp Orgs requires endorsement , if they are in same channel

rickr (Tue, 18 Dec 2018 16:07:16 GMT):
@GuillaumeTong I would relook at the sample just to see if you're following the same pattern. If you still don't see the issue probably put both JSDK and Fabric CA logging on trace level and use https://ctrlv.it/ to paste them both and report it on the #fabric-ca channel so they look at why it's getting that return.

But, our main knowledge is in Java SDK which we already(successfully) used for one project, deployed in production. Is there any document regarding requirements for programming model, what does it mean from SDK point of view to support this model?

tballast (Wed, 19 Dec 2018 15:47:25 GMT):
Does the comcept of having a single client performing actions for multiple organizations make sense, or should each organization have it's own client?
For example, in the End2EndIT.java there is only one HFClient object but it works on behalf of both organizations, though each org has a separate channel and separate peers and they are not mixed. Is this just for illustration purposes?
tballast (Wed, 19 Dec 2018 15:50:45 GMT):
I suppose that if two organizations are communicating on the same channel, each one should be running it's own client, or at very minumum a client object per org?
rickr (Wed, 19 Dec 2018 15:53:24 GMT):
@tballast Well in reality, I would find it highly unlikely that even in a single application instance running on behave of an organization would be using more than one client or organization. I would think the biggest use case is each application instance is just using one organization .

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=7cfE2HdkuWSqRwEtW) @rickr Rick. I may be not clear with my question? Stating again . I have one channel created by Org1 having mspId as Org1MSP. Second Org which is Org2 have mspId as Org2Msp.
If peer of org1 as PeerOrg1 and peer of org2 as PeerOrg2 joins the channel.
Now when if we make client using Org1 crypto material and needs endorsement from peer1 and peer2. It works. However If I create client using Org2 crypto materials need endorsement from
Peer1 and peer2. I get error from peer1 as “Sending proposal to peer0.org1.example.com failed because of: gRPC failure=Status{code=UNKNOWN, description=access denied: channel [mychannel] creator org [Org2MSP], cause=null}” Is this correct behavior.
Will I not get endorsement from peer1 if peer2 from org2 needs endorsement from peer1 of Org1(The creator of channel).

@schinivision IMO take the to get the End2endIT test running with TLS and see what is they do. Best follow in a debugger - take the time a day or so and will probably go a long way to making things easier. Your url isn't even grpcs and your server seems to want TLS .

The JSDK uses what Fabric uses. As a user you set at user context the key attributes of that which identifies an identity is the MSP ID and x509 Certificate or your derived idemix credentials.

Guys, in HFCAClient.register() i don't see that caName is being used(for example like it is used in enroll method). How can i register user on CA that have multiple servers which means caName must be specified? Is this a bug?

Hi experts..if the endorsment policy is not satisfied then the block shouldnt be added to the chain, correct?However from below peer logs i see that the blocks are being added inspite of endorsement policy failure.Any explanation would be helpful.

String cert = "src/test/fixture/sdkintegration/e2e-2Orgs/FAB_CONFIG_GEN_VERS/crypto-config/peerOrganizations/DNAME/ca/ca.DNAME-cert.pem"
.replaceAll("DNAME", domainName).replaceAll("FAB_CONFIG_GEN_VERS", FAB_CONFIG_GEN_VERS);

@StefanKosc There's way to little information known, or even _exactly_ what you mean by _freezes_ . Is your code trying to wait on the future returned by the sendTransaction ? If yes, are all the peers with eventingservice enabled reporting?. The SDK trace should show that if enabled on trace level.
versus (Mon, 07 Jan 2019 17:52:31 GMT):
@rickr first, thx for leading the jsdk development. we're using it for almost a year, appreciate your work. we were looking at things in hlf roadmap (namely: token management and finalization of private data collections in 2.x) and wondering whether these functionalities would require adjustments on sdk level. if so, are these already planned to be tackled in the near future?
rickr (Mon, 07 Jan 2019 18:07:43 GMT):
@versus I don't manage the features or roadmap of the Fabric. We try to keep the SDK on par with it's functionality (best we can :) ). If you really want to know that status of those or other features you'd need to ask on the #fabric-questions channel. Right now the way I read the tea leafs is 2.0 is coming next and AFAIK the only thing there for sure now is the new chaincode lifecycle .
That will be a future impact as it changes how chaincode will be installed and instantiated ( _defined_ ).

Hi, what is the best way to check if the peer from the channel-object is available? e.g. I send my propsal to all peers. If one of the peers now will get an disconnect I will get an exception, that the peer is unavaible
akoenig (Thu, 10 Jan 2019 15:28:40 GMT):
is there a good way (e.g. the channel) check if all peers are availble? If not I can react? I saw something like the ServiceDiscoveryIT?

hi, i'm trying to execute 'getHFCAIdentities' from SDK, version 1.3. For some reason it doesn't work, i see in rca-server logs the following message: Invalid token in authorization header: Token signature validation failed
This snippet is also used in another project where 1.2 SDK version is used and it works fine. I noticed that 'getHTTPAuthCertificate' method in HFCAClient is changed a bit in 1.3 and wondering if i need to make some changes on SDK side for 1.3. Btw, fabric version is 1.4-rc2

where do we add external go dependenices so that while deploying the chaincode using fabric-java-sdk , the chaincode builder picks it up accordingly?
akoenig (Fri, 11 Jan 2019 07:19:51 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=2fcdT9HF9WsDvGENu) @giacomo.minighin okay, thanks. But I don't see any example where the test checks the status of the peer? It checks if the the transaction was successfull or not (or am I wrong?) Because if this is the common method I can call a method first (like @rickr mention it) and check if the peer is available before I call it.

Hi.

@rickr Thanks for the Reply... But if I understand the code correctly than this is how you extract the payload from the chaincode query on a Success case... If L697 throws an error (which happens if the chaincode returns a shim.error) this exception will be caught in L711... But what I am interested is in the message that the shim.error returns in the chaincode... But the SDK just throws an Exception, and within that exception the message reads "Proposal response invalid"... is this because the SDK could not decode the response that is sent within shim.error?

@schinivision I think I looked at this once before and it would mean parsing it. Something I won't do. I think your chaincode can set a response like 4xxx that won't throw an exception and would not be considered success and you can get that status code.

hi guys, how to submit multiple transaction into 1 block?
schinivision (Thu, 17 Jan 2019 13:46:12 GMT):
@rickr Hi. I looked at the implementation of the go chaincode and there is just the two option -> shim.success returns a http 200 and -> shim.error returns a 500... therefore I wanted to parse the error.. because I am limited in the stati that I could interpret.
schinivision (Thu, 17 Jan 2019 13:49:36 GMT):
@KenvinNguyen as far as i know this is determined by the configtx.yml of the hyperledger that you connect to... Either the batch timeout will determine how much transactions will be in one block... (eg. you have a batch timeout of 2 seconds -> if you submit only one transaction per 2 seconds a block will only contain that one transaction) or the max message count (e.g. if you have a max message count of 10 then a block will never contain more than 10 transactions)

Hello,
I know this question is relevant for #fabric-ca, but since I am using the fabric-sdk-java, I thought the question might be relevant here as well.
I am trying to implement the following scenario:
Org1 is creating a channel and is installing Java chaincode. Org2 and Org3 need to add a transaction, i.e. call a method of the chaincode, without revealing their identity. It is really important that no user from Org1 knows which organization created the transaction, i.e. if it is a member of Org2 or Org3. From my research I found out that this is supposed to be done with Idemix.
I am now stepping on top of the basic-network. I successfully managed to install the chaincode to the peer and am invoking it without problems. However, when I try to pass the user enrollment through the idemix `caClient.idemixEnroll`, the same scenario is not working. I have an `access denied` response. Error in the peer logs is: `ValidateProposalMessage -> WARN 056 channel [mychannel]: MSP error: could not decode the PEM structure`
I tried editing the policies in configtx.yml and in the chaincode configuration during instantiation, but without any success.
My question is, first: do you think this scenario that I described is feasable with fabric and fabric-ca, and second, what might be the problem with the Idemix enrollment?

schinivision (Mon, 21 Jan 2019 14:03:48 GMT):
@KenvinNguyen I am not that deep into the user abstraction implementation. Here is how I understood it... In your scenario, if two users have the same read rights to the same channel (ledger) then yes, both could see all the results in the block (excluding the new private data feature, I haven't looked into that.) If you want to separate it you have to use different channels or look into the private data feature... But as far as I know... every transaction that is within the same ledger can be read by all participants that have a read permission on that ledger...@rickr knows maybe more about that.
rickr (Mon, 21 Jan 2019 14:37:47 GMT):
@dan13 It depends on your CC endorsement policy. There's something of an example that demos that in https://github.com/cr22rc/fabricSDKJavaMultiDomainSample if you follow the example comment real closely (needs run with older version of sdk but same principle)
rickr (Mon, 21 Jan 2019 14:45:52 GMT):
@milko.mitropolitsky Your beyond my understanding of idemix but you scenario _I think_ is exactly what Idemix is for. I really would post the error on #fabric-ca unless there seem to be an actual JSDK api issue. @adc ^^^

@rickr thanks, I'll dig into that -- scenario is chaincode policy requiring endorsement from at least one peer in 2 (both) Orgs, when I tried this having Org 1 client with Org 1 user sending proposal to Org 1 and Org2 peers (using single HFClient and Channel object), the Org 2 peer rejected the transaction because it was signed by user from Org 1 MSP (I will have to re-set up to capture exact error and report back)

so there is no other way
rickr (Wed, 23 Jan 2019 19:03:52 GMT):
what are you trying to do ?
ManjeetGambhir (Wed, 23 Jan 2019 19:05:11 GMT):
it was observed that when eventhub disconnect with peer and reconnect after sometime, inbetween commited block got missed by eventhub
rickr (Wed, 23 Jan 2019 19:05:46 GMT):
you really should be using the peer eventing service
ManjeetGambhir (Wed, 23 Jan 2019 19:05:51 GMT):
i was to recover block events on reconnect
rickr (Wed, 23 Jan 2019 19:06:05 GMT):
2.0 is removing eventhubs
ManjeetGambhir (Wed, 23 Jan 2019 19:06:16 GMT):
I know ..but we are on production with fabric 1.0.1
ManjeetGambhir (Wed, 23 Jan 2019 19:07:01 GMT):
peer eventing model is planned later
rickr (Wed, 23 Jan 2019 19:10:06 GMT):
the peer eventing takes care of missed blocks by default
rickr (Wed, 23 Jan 2019 19:10:28 GMT):
it tries to start where it left off
rickr (Wed, 23 Jan 2019 19:10:55 GMT):
assuming the client stays up
kelvinzhong (Thu, 24 Jan 2019 02:47:44 GMT):
@rickr hi rick, i'm confusing that seems fabric try to implement a raft-based ordering service then move on to BFT-based ordering service, but as i know, the consensus of fabric is based on a transaction flow and the ordering service can't altered any transaction on it's own, why fabric care the consensus between the ordering service?

even the BFT-based ordering service is delivered, i can't tell what's the different between Kaffka-based ordering service, even worse the BFT-based ordering service might slower in ordering.

hello
are there any tools which can be used to run performance testing against sdk application?
or are there any test scenarios how do to this? I mean, should I measure the performance by sending request to an application? or are there any other ways to do this?
yulong12 (Fri, 25 Jan 2019 04:56:51 GMT):
Hi everyone. I want to ask a question. I set the endorpolicy is ```
dentities: # list roles to be used in the policy
user1: {"role": {"name": "member", "mspId": "Org1MSP"}} # role member in org with mspid Org1MSP
user2: {"role": {"name": "member", "mspId": "Org2MSP"}}
policy: # the policy each MUST sign
2-of: # signed by one of these groups can be -of where is any digit 2-of, 3-of etc..
- signed-by: "user1"
- signed-by: "user2"
``` When I execute invoke ,it doesn't work
yulong12 (Fri, 25 Jan 2019 04:57:05 GMT):
so who can help me?
rickr (Fri, 25 Jan 2019 14:17:37 GMT):
@yulong12 its not the user signing it the peers (really the org the peer belongs to)
rickr (Fri, 25 Jan 2019 14:21:57 GMT):
@kelvinzhong If you're speaking of the new Raft based instead of Kafka Orderer _option_ there is no change in how the SDK will handle. I've been _told_ the Raft based allows a more simplified installation and overhead. For a more deep discussion I would recommend #fabric-orderer channel.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=4Q5Yq5WdRT8YpJEPM) @kelvinzhong the order is still a sensitive operation, because when two transactions conflict with one another, the first one will be marked valid and the second one invalid at the time the block is committed to the ledger. so people worried about bad players on the network do care.

How do you disenroll a user? I am using golang chaincode and java sdk, fabric v 1.2
skarim (Mon, 28 Jan 2019 14:30:14 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=TpgNq2CDvkgfFuu2S) @kevinkbc You can revoke a user or a specific certificate, but if you are interested in "disenrolling" a user then you probably would like to revoke all it's certificate. See here for an example on how to revoke: https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric_ca/sdkintegration/HFCAClientIT.java#L326

rickr (Tue, 29 Jan 2019 22:58:56 GMT):
@GianlucaPinto The SDK provides examples in the integration test. IMO best to take the time with a debugger and walk through them.

hi @rickr
what format of an endorsement policy should be used to convert it bytes and use it for method `ChaincodeEndorsementPolicy#fromBytes(policyBytes)`
that format is not working
https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/fixture/sdkintegration/chaincodeendorsementpolicy.yaml
I saw it is in use with method `ChaincodeEndorsementPolicy#fromYamlFile(yamlFile)` in the End2EndIT.java, but I'm interested in method `fromBytes`
I've tried to convert a string `OR('org1MSP.member')` to bytes, chaincode is instantiated successfully, but I'm getting the error during transactions:
```
2019-01-30 14:25:52.724 UTC [committer/txvalidator] validateTx -> ERRO 25b VSCCValidateTx for transaction txId = c298e55a7b1e2b4cc65a5d9685e0ea7ae633f2750fb66b40ebe21823c7f0e836 returned error: validation of endorsement policy for chaincode common in tx 2:0 failed: Error unmarshaling to SignaturePolicy: proto: can't skip unknown wire type 7
```
rickr (Wed, 30 Jan 2019 14:57:17 GMT):
@gravity Looking at the code all methods other than fromBytes converts and sets field policyBytes. So fromBytes sets that directly
gravity (Wed, 30 Jan 2019 15:05:14 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=dkDsWRTZX5xRSCxJc) @rickr that's weird
because if I read a policy from a yaml file to bytes and set it here, it does not work
rickr (Wed, 30 Jan 2019 15:36:57 GMT):
No the bytes there would be raw protobuf not a yaml file that was read in as bytes
akoenig (Wed, 30 Jan 2019 15:44:15 GMT):
Hi, I have a peer that is in two channels. And we work with a BlockListener in the network. When we install now a chaincode we get this warning from the channel:
akoenig (Wed, 30 Jan 2019 15:44:25 GMT):
```
if (!Objects.equals(name, blockchainID)) {
logger.warn(format("Channel %s eventqueue got block event NOT FOR ME channelId %s from %s", name, blockchainID, from));
continue; // not targeted for this channel
}
```
akoenig (Wed, 30 Jan 2019 15:44:56 GMT):
are we doing something wrong/bad? Or is this the normal behaviour that one channel gets the event from another channel?
rickr (Wed, 30 Jan 2019 15:45:15 GMT):
do you have two peer objects for each channel ?
akoenig (Wed, 30 Jan 2019 15:45:21 GMT):
yes
akoenig (Wed, 30 Jan 2019 15:46:25 GMT):
we call `final Peer peer = client.newPeer(peerName, peerLocation, peerProperties);` for each peer
akoenig (Wed, 30 Jan 2019 15:46:25 GMT):
we call `final Peer peer = client.newPeer(peerName, peerLocation, peerProperties);` for each channel
rickr (Wed, 30 Jan 2019 15:47:44 GMT):
two different channles objects
akoenig (Wed, 30 Jan 2019 15:50:50 GMT):
yes, for each channel a new object with new peers
rickr (Wed, 30 Jan 2019 15:51:49 GMT):
is the channelId the other channel ?
akoenig (Wed, 30 Jan 2019 15:51:56 GMT):
yes
rickr (Wed, 30 Jan 2019 15:53:36 GMT):
are you getting all the events you expect on the respective channels ?
akoenig (Wed, 30 Jan 2019 15:53:43 GMT):
yes
akoenig (Wed, 30 Jan 2019 15:57:02 GMT):
we are using the same eventhubs might be this the failure?
akoenig (Wed, 30 Jan 2019 15:57:15 GMT):
our test org has always the same eventhubs
rickr (Wed, 30 Jan 2019 15:58:58 GMT):
you using eventhubs ?
rickr (Wed, 30 Jan 2019 15:59:25 GMT):
Please move over to peer eventing
akoenig (Wed, 30 Jan 2019 15:59:37 GMT):
thought we need eventhubs for the blockchainlistener or are they not needed?
rickr (Wed, 30 Jan 2019 15:59:57 GMT):
They've been deprecated for some time.
akoenig (Wed, 30 Jan 2019 16:00:13 GMT):
so they are not needed for blockevent-listener?
akoenig (Wed, 30 Jan 2019 16:00:16 GMT):
then i will remove them :D
rickr (Wed, 30 Jan 2019 16:00:31 GMT):
what version are you on ?
akoenig (Wed, 30 Jan 2019 16:00:35 GMT):
1.2
akoenig (Wed, 30 Jan 2019 16:00:43 GMT):
but we want to swtich to 1.4 soon
akoenig (Wed, 30 Jan 2019 16:03:31 GMT):
we have implemented a BlockListener from the Java-Sdk. And thought we need EventHubs for this (and saw them from the tutorial). But if they are not needed we can remove them.
rickr (Wed, 30 Jan 2019 16:03:48 GMT):
https://github.com/hyperledger/fabric-sdk-java/blob/master/docs/release_v1.1.0_notes.md#fabric-v10-considerations
rickr (Wed, 30 Jan 2019 16:05:58 GMT):
1.4 sdk still has eventhubs to connect back to older version but fabric 1.4 does not support them
2.0 sdk will have eventubs removed
akoenig (Wed, 30 Jan 2019 16:09:25 GMT):
Okay, thank you very much for the informatin. So I will remove the logic and will have a look if it works.
akoenig (Wed, 30 Jan 2019 16:24:25 GMT):
@rickr thanks for your help, it's working now :)
akoenig (Wed, 30 Jan 2019 16:30:03 GMT):
but do you know why the class is not annotated with "deprecated"? Or are they in 1.4?

@helpsolution I would think either the _registerChaincodeEventListener_ or _registerBlockListener_ method of your _Channel_ instance

rickr (Thu, 31 Jan 2019 13:50:58 GMT):
@fanjianhang Just googling ( https://github.com/lightbody/browsermob-proxy/issues/712 ) seem to be a bouncy castle version error.
rickr (Thu, 31 Jan 2019 13:57:52 GMT):
@helpsolution there is something that starts a channnel peer listeners at a specific block
https://github.com/hyperledger/fabric-sdk-java/blob/a2140f9bba57a63c58d9ee8579fea7164bf3beb2/src/test/java/org/hyperledger/fabric/sdkintegration/End2endAndBackAgainIT.java#L276-L296

@rickr Thanks, but it is not convenient((
helpsolution (Thu, 31 Jan 2019 14:49:04 GMT):
@rickr Is it possible to add functionality for selecting block numbers when registering event listeners as in node js sdk?
rickr (Thu, 31 Jan 2019 14:51:54 GMT):
Not on the list so far. I think you can always create a new client / channel / peer for specific block listener .. not maybe optimal but do think workable
helpsolution (Thu, 31 Jan 2019 15:52:34 GMT):
@rickr Ok, thanks)
helpsolution (Thu, 31 Jan 2019 16:04:09 GMT):
@rickr I encountered the following problem. I have 100 blocks for example, next I subscribing to events starting 0 block and back I got events without keeping order of blocks. But this very important. How solve this problem?
rickr (Thu, 31 Jan 2019 16:39:47 GMT):
that can happen cause of java thread dispatching ... -> I've used this https://ctrlv.it/id/164213/2696686186
helpsolution (Fri, 01 Feb 2019 08:44:25 GMT):
Thanks, but this is not optimal for my task... Is it possible to use 1 thread to receive events?
rickr (Fri, 01 Feb 2019 13:39:20 GMT):
Not today . Why does that not work for you ? In theory you could put in that code snippet I gave just some code that puts the events in to a queue and then have your _1 thread_ read from it.
helpsolution (Fri, 01 Feb 2019 14:38:17 GMT):
It is right, but if i have 10000000.. blocks it reduces performance
helpsolution (Fri, 01 Feb 2019 14:38:17 GMT):
It is right, but if i have 10000000.. blocks for example, it reduces performance
helpsolution (Fri, 01 Feb 2019 14:38:17 GMT):
It is right, but if I have 10000000.. blocks for example, it reduces performance
rickr (Fri, 01 Feb 2019 14:40:46 GMT):
have you tried with 10000000 blocks ? Was it not acceptable ?
helpsolution (Fri, 01 Feb 2019 14:42:25 GMT):
No, but the approach is a bit strange.
rickr (Fri, 01 Feb 2019 14:46:26 GMT):
I'm _guessing_ what ever you're doing with processing each block will more than likely be significantly slower than any queuing and will be the processing you would not want do with just _1 thread_ if possible.

The fabric sends messages with preservation of order, but on the side of sdk the order is broken due to multithreading. It's right?

hi everyone,
how can i create an purely Android App with hyperledger fabric integeration ?????
gravity (Sun, 03 Feb 2019 21:37:37 GMT):
Hi @rickr
are there any reasons in caching fabric-related objects in an application?
For example, HFClient. An object of HFClient class is created with the user context of the caller. Is it ok to create this object every time user sends query/transaction?
rickr (Mon, 04 Feb 2019 13:30:55 GMT):
@AsifJaved https://github.com/hyperledger/fabric-sdk-java#is-android-supported
rickr (Mon, 04 Feb 2019 13:34:46 GMT):
@gravity I don't think that would be optimal in general. It may be ok if your application is rarely sending work to the Fabric .. but I would think that would be atypical use
rickr (Mon, 04 Feb 2019 13:35:03 GMT):
@helpsolution Threads are created as needed.
pumicerD (Mon, 04 Feb 2019 13:58:34 GMT):
Hi, how would I use the Java SDK to register an admin user ?
Much like this example given for the CA client CLI :
`fabric-ca-client register --id.name admin2 --id.affiliation org1.department1 --id.attrs 'hf.Revoker=true,admin=true:ecert'`
I can set username and affiliation with `RegistrationRequest rr = new RegistrationRequest("admin2", "org1.department1")`
the revoker attribute with `rr.setType(HFCAClient.HFCA_ATTRIBUTE_HFREVOKER)`
what would be the way to set the admin attribute ?
rickr (Mon, 04 Feb 2019 14:01:20 GMT):
CA Admin is already registered. I don't think via the api you register another. @skarim
pumicerD (Mon, 04 Feb 2019 14:06:36 GMT):
The CA Admin is the bootstrap identity created when starting the server with `fabric-ca-server start -b :`
Isn't it different than the Admin account generated by cryptogen ? (certs under _peerOrganizations/orgX/users/Admin@orgX_)
pumicerD (Mon, 04 Feb 2019 14:07:49 GMT):
That is the account I'm trying to register via the CA server, instead of cryptogen
rickr (Mon, 04 Feb 2019 14:09:32 GMT):
AFAIK You can't create a *Peer Admin* with the SDK api
rickr (Mon, 04 Feb 2019 14:10:27 GMT):
@skarim @smithbk ^^^
pumicerD (Mon, 04 Feb 2019 14:11:16 GMT):
Ok
smithbk (Mon, 04 Feb 2019 15:10:22 GMT):
@rickr The fabric-ca-server REST API allows specifying attributes. The question is whether the java SDK APIs supports that.
rickr (Mon, 04 Feb 2019 15:11:35 GMT):
@smithbk setting those attributes will give a user peer admin capablities ? Join channels, install chaincode etc
smithbk (Mon, 04 Feb 2019 15:13:02 GMT):
@rickr No, I thought @pumicerD was attempting to do the same thing that the `fabric-ca-client` command above does
rickr (Mon, 04 Feb 2019 15:13:35 GMT):
Thanks -- just want to make sure it's clear
pumicerD (Mon, 04 Feb 2019 15:14:53 GMT):
@smithbk @rickr I was trying to register a peer admin with this yeah
rickr (Mon, 04 Feb 2019 15:16:36 GMT):
Ok - then as stated that's not possible.
pumicerD (Mon, 04 Feb 2019 15:17:35 GMT):

hi Fabric Developers
just letting you know about the "Hyperledger Fabric Developer" community call (lasts approx 30-60 mins) currently scheduled for Thursday February 7th 5pm UTC (5pm UK, 12pm ET, 9am PT).
The plan is to initially host this community call bi-weekly via Zoom webconference and is aimed at :
- helping the worldwide Fabric Developer community grow in their development journey (eg. developing applications, smart contracts, chaincode, developing clients, using the SDK etc - eg. whether its NodeJS, Java, Go etc etc)
- caters for the developer perspective and the developer community.
- help developers understand / hear more about exciting new things in Fabric,eg. features upcoming or work in progress - ie things that appeal to the developer
- to foster more interest, best practices etc in developing with Hyperledger Fabric.
- opportunity to ask questions of the Fabric team eg. you may have feedback/questions on your experiences developing with Fabric
- to share stuff you've done with the community, eg sample code / sample use cases that others may be interested in
If you wish to share content on a call, just let me know via email direct or DM me on Rocketchat (ID: mahoney1) and I'll put an item on the agenda. Provide the following:
- the topic (state whether its presentation, or demo etc)
- the full name of the presenter, and
- approx length of your pitch in minutes
The Zoom webconference ID is https://zoom.us/my/hyperledger.community and the aim is to grow interest in the Fabric developer ecosystem (this 'Fabric Developer' call clearly has a much broader scope as indicated - feel free to make suggestions too !).
The current agenda is shown here -> https://wiki.hyperledger.org/display/fabric/Fabric+Developer+-+Meeting+Agendas+
many thanks for your time - feel free to forward this email if you think it is of interest to a colleague.

I am trying to sign a query proposal with *Idemix* credentials.
Setup :
- added a MSP definition of type `idemix` in _configtx.yaml_ and added it to the profiles' _Organizations_
- generated the crypto material with both `cryptogen` and `idemixgen`, then channel artifacts with `configtxgen`
- mounted the generated _IssuerPublicKey_ and _RevocationPublicKey_ on the `fabric-ca` container I use as my organization's MSP
- get a `HFCAClient` instance for this server, enroll as the CA admin, register and enroll a regular user account (with the x509 MSP ID)
- get an `IdemixEnrollment` for this user (with the Idemix MSP ID)
- set the `HFClient` instance's user context to an `IdemixUser` created with this enrollment
- send the query proposal
I get the following error message in my _peer_'s logs :

pumicerD (Mon, 04 Feb 2019 15:54:03 GMT):
I am trying to sign a query proposal with *Idemix* credentials.
Setup :
- added a MSP definition of type `idemix` in _configtx.yaml_ and added it to the profiles' _Organizations_
- generated the crypto material with both `cryptogen` and `idemixgen`, then channel artifacts with `configtxgen`
- mounted the generated _IssuerPublicKey_ and _RevocationPublicKey_ on the `fabric-ca` container I use as my organization's MSP
- get a `HFCAClient` instance for this server, enroll as the CA admin, register and enroll a regular user account (with the x509 MSP ID)
- get an `IdemixEnrollment` for this user (with the Idemix MSP ID)
- set the `HFClient` instance's user context to an `IdemixUser` created with this enrollment
- send the query proposal
I get the following error message in my _peer_'s logs :

Looks like the peer is detecting the type of credential correctly (idemix) but the MSP id expected is _idemixMSP1_
pumicerD (Mon, 04 Feb 2019 15:57:31 GMT):
Is there something else I forgot to set here ? I can send queries and transactions just fine when using x509 credentials

Using NOfEvents to wait for transactions sent to the orderer to be commited on peers... say I have 2 peers I want to wait for but one of those peers drops offline, so will only going to get the transaction commit event from one of the two peers, is the CompletableFuture returned by `sendTransaction()` going to just hang forever (or fail with TimeoutException)? Or is there some logic in there that notices the peer dropping offline and will complete in some state with just the one (of two) events received?

Users need to put a timeout on their Futures
rickr (Tue, 05 Feb 2019 19:15:21 GMT):
Users need to put a timeout on their Futures Note that peer eventing services will continue to try and connect and start where left off. So, if it's just a glitch it should still recover
bestbeforetoday (Wed, 06 Feb 2019 10:00:26 GMT):
So if I want to notice that one of the two peers I would like to receive commit events from has dropped offline so that I can unblock after receiving the commit event from the single active peer, I need to use the peer eventing service directly instead of NOfEvents? And is there a handy code example of how that is done anywhere?

rickr (Wed, 06 Feb 2019 13:35:23 GMT):
So what do you plan on doing when you unblock ?
rickr (Wed, 06 Feb 2019 13:37:31 GMT):
How will you know when it just a temporary glitch that can recover ?
bestbeforetoday (Wed, 06 Feb 2019 13:43:08 GMT):
@rickr That link points to the NOfEvents source, right? I recall that isn't the code that actually does the listening; just that keeps track of what things events have been received from? And you mentioned already that it doesn't deal with peers going offline so I'd like to know how I can write code to deal with that. Can you help?
rickr (Wed, 06 Feb 2019 13:58:18 GMT):
I don't have code that deals with peers off line . I kind of like to understand your use case. Like I stated what do you plan to do ? I think applications should have been written to wait on the future for a specified time. If the application then gets a timeout the application can decide what's appropriate for it's own recovery. It could just give up and report the error back up. It can continue to poll the peers needed to see if the transaction is there. Decided if it sees it on one continue to assume it's good. Or some other action

bestbeforetoday (Wed, 06 Feb 2019 14:08:26 GMT):
What I'd like is to say, look for commit events from all peers in a particular org, and to unblock when for every one of those peers I have either received a commit event or the peer is observed as offline. Then, provided I have received at least one successful commit and no errors, move on. I don't want to wait some arbitrary period of time for a peer that is observed as offline to (maybe or maybe not) come back online.
rickr (Wed, 06 Feb 2019 14:09:12 GMT):
How do you determine a peer is offline ?
bestbeforetoday (Wed, 06 Feb 2019 14:09:37 GMT):
Does the peer eventing service provide any notification of a communication failure with a peer?
rickr (Wed, 06 Feb 2019 14:10:29 GMT):
It has a connect handler that makes attempts to reconnect ...
bestbeforetoday (Wed, 06 Feb 2019 14:10:48 GMT):
Will that allow me to do what I described above?
rickr (Wed, 06 Feb 2019 14:11:38 GMT):
I don't know how you can say the peer is off line as opposed to just temporarily down or a network glitch
bestbeforetoday (Wed, 06 Feb 2019 14:12:11 GMT):
Let's treat all those as the same case. Not currently communicating. Will the connect handler allow me to achieve that?
rickr (Wed, 06 Feb 2019 14:12:48 GMT):
You can overried it do what you want
bestbeforetoday (Wed, 06 Feb 2019 14:13:13 GMT):
Are there any examples of this API in use? I'm struggling to find examples and documentation to understand usage
rickr (Wed, 06 Feb 2019 14:13:47 GMT):
you see the the what default handler is doing and start from there
bestbeforetoday (Wed, 06 Feb 2019 14:14:10 GMT):
Can you point me at the right point in the code for that?
rickr (Wed, 06 Feb 2019 14:15:48 GMT):
I thought I sent it to you already in a note
https://github.com/hyperledger/fabric-sdk-java/blob/a2140f9bba57a63c58d9ee8579fea7164bf3beb2/src/main/java/org/hyperledger/fabric/sdk/Peer.java#L571
bestbeforetoday (Wed, 06 Feb 2019 14:23:40 GMT):
Thanks. So I'd need to:
1. Register a disconnect handler for all the peers.
2. Register a BlockListener with the channel to look for a specific transaction commit event.
3. Somehow tie together myself disconnects to current listening tasks.
Is that roughly correct?
bestbeforetoday (Wed, 06 Feb 2019 14:24:37 GMT):
Any way to get the current disconnect handler before calling `setPeerEventingServiceDisconnected()` so I can delegate to the original handler with my replacement safely?
bestbeforetoday (Wed, 06 Feb 2019 14:25:05 GMT):
How do I get information from the block events?
bestbeforetoday (Wed, 06 Feb 2019 14:26:42 GMT):
Am I just after `getTransactionID()` and `isValid()` on the transaction events to know I've received a successful commit?
rickr (Wed, 06 Feb 2019 15:18:13 GMT):
Sounds about right in general. Familiarize yourself with integration test they show most what the sdk has. There's in End2endIT that has blockwalker goes through a block

Hi all
is it possible to describe an endorsement policy so a transaction should be endorsed by 3 peers?
the actual question is, how an endorsement policy correlates with the number of endorser peers to which a transaction is sent?
I read the documentation about endorsement policies, but it is still quite confusing for me
thanks in advance

@gravity I don't think there's a way to pick a specific peer. Endorsements are by organization
https://github.com/hyperledger/fabric-sdk-java/blob/a2140f9bba57a63c58d9ee8579fea7164bf3beb2/src/test/fixture/sdkintegration/chaincodeendorsementpolicyAllMembers.yaml
That is an example of needing both peers organizations to sign the endorsement for the integration tests.
If the documentation is not clear I highly encourage you to bring this up in the #fabric-documentation so they can look on improving it.
rickr (Thu, 07 Feb 2019 13:48:36 GMT):
@gaijinviki and @gravity Our verification test are run with TLS enabled and pass. So I'm fairly certain the required dependencies are ok.
gaijinviki (Thu, 07 Feb 2019 14:01:19 GMT):
@rickr I had to add the dependencies to make it work. Maybe something wrong with my setup. And I am not using TLS, the error occurred during eventing initiation `org.hyperledger.fabric.sdk.Peer.initiateEventing(Peer.java:148)`

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=QmSd8F5Cth9JHchk6) @rickr Actually I do use an endorsement policy similar to this. But I confused it with the validation of transaction proposal responses from the endorsement peers. I thought that if I have a policy (now I know that this policy is invaild) `AND("org1.peer", "org1.peer", "org3.peer")`, means that a transaction proposal must be sent to at least 3 endorsement peers for the endorsement.

rickr (Thu, 07 Feb 2019 15:30:09 GMT):
Endorsements are by organization. You would need an endorsement from a peer for each organization in the case I pointed to. If you don't have that and your send your endorsements to the Orderer the committers SHOULD mark the transaction as bad.

gravity (Thu, 07 Feb 2019 18:12:18 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=HJe2RmrEh8iKzBaSr) @rickr now it's clear. transaction endorsement is done under the hood by the organization's entity that is requested in the policy.
jdfigure (Thu, 07 Feb 2019 21:06:26 GMT):
@gravity @rickr I think I've discovered why Service Discovery wasn't working (peer reporting `TLS handshake failed with error tls: client didn't provide a certificate`).
It seems there's a bug in the `org.hyperledger.fabric.sdk.Channel#addPeer(org.hyperledger.fabric.sdk.Peer, org.hyperledger.fabric.sdk.Channel.PeerOptions)`
method when using the `clientCertBytes` property instead of `clientCertFile`. This check fails to find the `clientCertBytes` property:
```
if (peerOptions.getPeerRoles().contains(PeerRole.SERVICE_DISCOVERY)) {
final Properties properties = peer.getProperties();
if ((properties == null) || (isNullOrEmpty(properties.getProperty("clientCertFile")) &&
isNullOrEmpty(properties.getProperty("clientCertBytes")))) {
TLSCertificateBuilder tlsCertificateBuilder = new TLSCertificateBuilder();
TLSCertificateKeyPair tlsCertificateKeyPair = tlsCertificateBuilder.clientCert();
peer.setTLSCertificateKeyPair(tlsCertificateKeyPair);
}
discoveryEndpoints.add(peer.getEndpoint());
}
```
Calling `properties.getProperty("clientCertBytes")` returns null because the property value is not a string. Instead, it should be using `properties.containsKey("clientCertBytes")`.
When I used `clientCertFile` instead, everything works. The reason the ServiceDiscoveryIT tests work is because they are also using cert files instead of cert bytes.

Is there a Java SDK equivalent to Go SDK Client.Execute (https://godoc.org/github.com/hyperledger/fabric-sdk-go/pkg/client/channel#Client.Execute) which "automatically chooses endorsers, service discovery, requests endorsements, signature validation, submits to the ordering service, watches events for commit, configurable retries" per https://jira.hyperledger.org/browse/FABN-692?focusedCommentId=48582&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-48582?

gaijinviki (Fri, 08 Feb 2019 05:23:47 GMT):
Hello, I am using java sdk to do service discovery during channel initiation. The peer external endpoint is set to `CORE_PEER_GOSSIP_EXTERNALENDPOINT=mycustomurl:8051` and so the sdk can connect to the peer, but the discovery peer is passing the orderer address as `orderer0.example.com`, and hence the sdk cannot resolve that. How can I change the external address of the orderer, preferably via some environment variable ?

Under the covers it's an ExecutorService and you can set the thread count in there.
You will hit the "my thread doesn't return until the orderer has cut a block" limit too if you are trying for throughput. You'll see...

@vtech I don't see from an SDK perspective it would make a difference. From the SDK the API is pretty much independent. With out any more details pointing to an SDK issue the question I think you should ask on the #fabric-peer-endorser-committer is what testing they've done prior to release that shows it's working.

rickr (Tue, 12 Feb 2019 15:39:40 GMT):
@chill37 The endorsement policy is specified when the chaincode is instantiated. It can't be expected that the SDK knows what the endorsement policy really is for any any chaincode. The chaincode could have been instantiated by some entirety different organization than the client/SDK is running in. Thus service discovery. Short of that there _may_ be out of bound knowledge/agreement/policy what is needed.

@rickr I see.
But since the chaincode has its policy written (somewhere), can't I load the policy that is lying somewhere? isn't there a way to load this? somewhere from Channel.class or ChaincodeSpec?
I know and tested the service discovery where we can load and select peers based on the policy. I was hoping I could do the same without the discovery.
For now, my setup is that I'm instantiating the Chaincode with cli. Then I use JAVA Sdk to query/invoke. But I would like to know the policy so that I can only call the necessary peers.
Thanks!

@rickr oh now I get it. I can use service discovery to get the endorsement layout only right?
At first I thought service discovery should be only used when query/invoke.
is it possible to use service discovery functions even when I don't have any peers property as "discover:true"?

@vtech can you _simplify_ ? Add to your chanincode a new function that just returns back a string "i'm good" and do that GetAttributeValue so there's no privadata involved. Also as stated I don't think the place to start here is on this channel. It's really a #fabric-chaincode-dev channel where issue rise while executing chaincode should be worked out. The experts on that should be monitoring it.

rickr (Fri, 15 Feb 2019 19:33:47 GMT):
@jjean If _you're just starting off_ I'd recommend what the README.md suggest. Have it pass the Integration test. Build Successful indicates the tests are working with the fabric configuration provided (_fabric.sh_ script) and all is setup. Then import and get everything resolved in your IDE. Debugging the integration tests shows everything you can do and lets you follow the code. Once done you have a place to start copying code for your own application.

hi @rickr
what is the point of setting up the `version` field in `ChaincodeID` for `TransactionProposalRequest` and `QueryByChaincodeRequest` when it's actually is ignored?
for example, if I install a chaincode on channel `ch1` version `1.0` and instatiate it, and later try to send transaction proposal or query request, I can put any other version to the ChaincodeID of the proposal/query, for example `1.0qwerty` and it will proceed. But, if do not put version to the `ChaincodeID`, it will throw NPE
jjean (Mon, 18 Feb 2019 12:38:53 GMT):
Hi, how could I turn off the following logs for Java SDK?

rickr (Mon, 18 Feb 2019 13:59:09 GMT):
@jjean You can control sdk logging by using log4j . That is DEBUG and by default the SDK is in WARN level which should not produce that.
rickr (Mon, 18 Feb 2019 14:14:54 GMT):
@gravity ChaincodeID mirrored protobuf structure. It was to uniquely identify the chaincode but in the early days things kept chainging. The idea was if you set it appropriately the SDK would use from it what was needed. Please submit a JIRA for the NPE case you're observing with a quick example that should not happen. It must be a non common scenario as no one as reported it. There is a change coming in 2.0 that entirely changes chaincode deployment and ChaincodeID should will not be used anymore with that.
gravity (Mon, 18 Feb 2019 16:52:12 GMT):
@rickr
ok, will report that.
there is another question: what happens after chaincode upgrade? does the chaincode with the newer version become the default chaincode to be called on all subsequent chaincode invocations?

@gravity yes only the latest.

Has anyone experienced a high number of connections from the Java SDK to an anchor peer? We're trying to track down a memory issue on our peers (seeing upwards of 20GB RAM used by our anchor peer). We're seeing that the SDK is establishing 22K connections to the anchor peer under load. It seems to be related to the default ExecutorPool settings in `HFClient`. We've turned off all event listeners. Any ideas?
rickr (Tue, 19 Feb 2019 18:11:25 GMT):
@jdfigure I've not heard of any issues. I knew one group that was creating the channel doing the request, shutting down the channel .. repeat for each request which caused problems. So what version of the SDK and when you say you turned off all event listeners .. I assume that just added info and the problem persists?
jdfigure (Tue, 19 Feb 2019 19:25:56 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=bgMisZ9Ns3SQS4BXM) @rickr Yes, the fact that we turned off event listeners was added info. We were doing something similar (i.e. creating HFClient and channel per request).
Right now we're modifying our our approach to use a singleton HFClient instance, re-using channels on that client, and using the TransactionRequest.setUserContext for transaction-level user context. I assume that's a better model?
rickr (Tue, 19 Feb 2019 20:12:05 GMT):
@jdfigure yes

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=hfoYFGEt75SMtKWmW) @gravity If the certificate is expired, you would not be able to use `reenroll` as the certificate would fail to pass validation cause it's expired. In this case, you would have to use `enroll` using your username/password. Once, you enroll you will get back a new certificate and this certificate would have to be used by the peer.
gravity (Tue, 19 Feb 2019 22:02:18 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=yRGd8WWxT9jd3zovM) @skarim for example, if a certificate is going to be expired in, let's say, 5 days, I can `reenroll` peer's certificate, and to use this reenrolled certificate a peer must be restarted, right?
and the same for the `enroll` when the certificate expired - peer must be restarted, right?
are there any other actions to be done to accept this newly enrolled or re-enrolled certificate?
skarim (Tue, 19 Feb 2019 22:33:03 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=gkcw9Y2nRCdK2rprF) @gravity If it hasn't expired yet, then yes you can use `reenroll`. After getting the new certificate, a peer restart is required. I believe that should be it.

haven't had a need to go through the sdk for a while. is there a way to tell events that haven't been
aatkddny (Tue, 19 Feb 2019 23:24:31 GMT):
haven't had a need to go through the sdk for a while, and i'll do so tomorrow, but i'm trying to save some time searching.
we've been losing events because we've had some issues with peer instability in the cloud.
is there an example of a way to tell the events that haven't been triggered on a peer and to replay them in the sdk at all, or something i can co-opt, or am i going to be walking the blocks and dummying events from the tx manually?

aatkddny (Wed, 20 Feb 2019 13:07:45 GMT):
Answering my own question - haven't been there for a while. testPeerServiceEventingReplay in End2endAndBackAgainIT.java looks like just what I need. I'll leave this here in case anyone else has this issue.
rickr (Wed, 20 Feb 2019 13:54:45 GMT):
Hi @aatkddny yes that should be where you look at. However the SDK using peereventing services should try to continue to connect and would start getting the last block it seen. You can change behavior https://github.com/hyperledger/fabric-sdk-java/blob/d2bc6d50e362a140970a509ade25f2f2c69e6c0f/src/main/java/org/hyperledger/fabric/sdk/Peer.java#L523-571
So if you're client is up and running and the peer goes down and comes back up -- it _shouldn't_ miss blocks.
Obviously this dependent on memory and if your client goes down that's not going to help. Ultimately if an application really needs to be bullet proof it needs some blocklistener that tracks the blocks it has processed and persists that somewhere so if it needs to restart it can begin at that point.
aatkddny (Wed, 20 Feb 2019 16:07:49 GMT):
@rickr and that's what it looks like i'm going to end up having to implement.
in my case this set of peers don't always necessarily going down - they have other problems too that i won't air here - and they aren't under my direct control.
what we are seeing though is that we aren't reliably getting all the events, and we need them to guarantee integrity.

@gravity you will not receive it... you only receive events as blocks/transactions are committed... a shim error doesn't get past endorsement phase

Hi all
is it a good practice to have a singleton instance of the `HFClient` and set user context on transaction level (and do not set user context directly to the `HFClient`)?
our current implementation creates `HFClient` instance per user, but it seems like overhead.
rickr (Fri, 22 Feb 2019 14:17:06 GMT):
@Jamie Have to believe something local to your environment. I run that many times daily and so do many other users. This is the first report of an issue with it that I can remember.
rickr (Fri, 22 Feb 2019 14:20:35 GMT):
@gravity Most of the API lets you directly set the usercontext. I highly recommend doing that unless you only have one user. If your application is going to be multi-threaded there's no way you can control the user context by switching it on the client.
gravity (Fri, 22 Feb 2019 14:42:09 GMT):
@rickr
So, for example, I can create, let' say, 2 instances of `HFClient` - the first one for an admin (peer admin) and set user context for it after creating it. This instance I will be using only for admin actions, like create channel, install chaincode, instantiate etc. THere should be no problems because I have only one peer admin.
Also, I will create another HFClient instance, but won't set user context, only crypto primitives. This instance will be in use only for queries/transactions where I will set user context directly to the query/transaction proposals.
is this setup more or less ok?
rickr (Fri, 22 Feb 2019 14:44:57 GMT):
Yes that will work. But a bit overkill most likely, I think you should be able to just one instance of HFClient

Is there a way to call system chaincode(LSCC to be specific) directly and without using chaincode-to-chaincode?
I see that Java SDK supports some SCC natively, (e.g. queryinstalledChaincodes...etc) but I would like to call LSCC.GetChaincodeData
But, too many methods are hidden with a private method so can't call necessary parameters (such as sendProposalToPeers() in Peer class)
Is there another way?

rickr (Mon, 25 Feb 2019 13:13:32 GMT):
@dan13 I think you should only really need one HFClient in an application instance for most cases. Each organization has it's own private credentials artifacts so it's doubtful there would be cases or sharing those. The SDK doesn't know you application requirements so how you use the client context is probably highly dependent on that. If your application is such that a single user will start it and give credentials then probable just set it on the HFClient and your done. If your application instance is going to be switching between users most all APIs have a version that accepts the usercontext and then that's probably the better way to go. There should be no problem with a usercontext that creates the channel and then another usercontext uses it. I little bit of this is sort of showed in:

@rickr because I wanted to call the LSCC.GetChaincodeData to get the ChaincodeData struct(to get the policy out of it).
I can see that I can extend the LSCCProposalBuilder to build my own LSCC caller, but I need the Channel.sendProposalToPeers() function public to actually to querying. Is there a way I could propose and fabric dev would implement it? (e.g. via JIRA)

I'm _guessing_ you're not waiting for the committer peers to write the transaction. When you send the endorsements to the Orderer you would back a Future not till that future is done (.get()) would you know it's been written. Also this assumes you have peer's with the role of event listener. Another quick (hack) is to just after sending to the Orderer do a sleep for 30 sec :(

dan13 (Thu, 28 Feb 2019 19:26:48 GMT):
@rickr can you clarify "Not till that future is done (.get()) would you know it's been written" -- what exactly is "written" when the get() returns? Block created by orderer, block processed by all peers on channel, block processed by peer(s) you are listening to, that specific transaction committed by all peers on channel, that specific transaction committed by peers you are listening to, or something else?
FlorianStoica (Thu, 28 Feb 2019 21:25:00 GMT):
@rickr something else seems to be the problem even with sleep the result is the same

@FlorianStoica I ran https://medium.com/@aleksobol/explained-java-chaincode-in-hyperledger-fabric-fc63fccc84a3 -- perhaps that example will work better for you if you need java chaincode specifically. Doesn't take very long to get through.

rickr (Fri, 01 Mar 2019 13:07:55 GMT):
@gravity I've never used `join` Basically used two method calls *.get* which will make your code wait for the future to be resolved, essentially make it synchronous, or thenApply which is like a call back.

gravity (Fri, 01 Mar 2019 13:13:53 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=agrCMmCzrXkjDvud8) @rickr so, If I use `get` or `thenApply`, there is no need to define peers with the role `event_listener`, right?
rickr (Fri, 01 Mar 2019 13:23:05 GMT):
@dan13 Your code sends endorsed proposal to the orderer (transaction) to be actually written to the ledger it gets a Future as the result. Roughly committing peers get blocks from the orderer that has that transaction and then writes them to the ledger. Between that time any query for your result will not show up. Peers your application has as PeerRole.EVENT_SOURCE get notified that the block has been written and will complete that Future. So if you are waiting for the future via _.get._ or _.thenApply_ and you query for you result it should be evident.

@anjalinaik Basically it seems the peer hostname is not resolving from what I can tell. There was a bug in grpc 1.16 https://github.com/grpc/grpc-java/issues/5032 SDK 1.4 is using 1.17 but if you're on an older version could play a role.

Hey guys, I've created a single host setup using the fabric 1.1.0 images on an AWS instance and everything works fine on that setup.
I've then transitioned into using a multi-host setup with Docker swarm overlay network with 3 AWS instances. It seems to work fine for the most part except for every 2 hours where the peer resets the connection and I receive an error in the SDK (attached below). I thought it might have been affected by the network setup so I removed all the containers except for a single peer, single orderer, and single couchDB, but I still get the same error (still in an overlay network even though the other machines aren't used). The client that connects to the network is on a remote machine and uses only the default GRPC keepalive properties. Each request reuses a single HFClient and Channel object and not shutdown after the request finishes.

daijianw (Wed, 06 Mar 2019 08:12:56 GMT):
@rickr https://jira.hyperledger.org/browse/FABN-855 fixed the problem of node sdk can't install packaged chaincode. Is fabric java sdk now able to install packaged chaincode? Thanks.

@daijianw No not for <2.0 Everything changes with version 2.0 and I have code that will install the new chaincode package that it has.

hi @rickr
I'm running a network v1.4.0 and JSDK v1.4.0
when I do initialize a channel, sometime I get this exception
https://pastebin.com/4s2a2YH1
what can cause this exception? is it critical?
thanks in advance
rickr (Wed, 06 Mar 2019 13:48:09 GMT):
@gravity When you initialize if you have any peers doing service discovery it will start that. I think in this case that peer is not ready. Service discovery should retry later or when it's services is needed and it hasn't completed. So the short answer is _I think_ it's ok.

hi guys , i have a question:
when i use java-sdk v1.4.0 to install(instantiated) a chaincode(https://github.com/hyperledger/fabric-samples/tree/release-1.4/chaincode/marbles02/go)
i find there is no index in couchdb
but when i use cli(peer chaincode) install/instantiated the same chaincode , i find index in couchdb
rickr (Wed, 06 Mar 2019 14:43:22 GMT):
@james3443112 I'm _guessing_ for the SDK you're not specifying the meta data correctly See End2endIT.java search for meta-inf
james3443112 (Wed, 06 Mar 2019 14:45:47 GMT):
thx, i will check it
Antimttr (Wed, 06 Mar 2019 15:52:21 GMT):
so theres no examples of java being used to communicate via api, what front ends to people write for the java sdk?
Antimttr (Wed, 06 Mar 2019 15:52:27 GMT):
is it all native software?
dan13 (Wed, 06 Mar 2019 17:14:18 GMT):
@Antimttr One (of a myriad) possible full stack would be something like React JS UI -> Java (Spring Boot?) UI Service APIs -> Java Fabric Services (i.e., code that calls chaincode via Java SDK) -> HLF Chaincode. It's up to you to decide how to expose your application on Fabric to other applications to want use it.
Antimttr (Wed, 06 Mar 2019 17:15:49 GMT):
right
Antimttr (Wed, 06 Mar 2019 17:16:50 GMT):
like on my current POC, i'm modifying balance transfer, so im doing Laravel Gateway -> Nodejs SDK Fabric Services API -> HLF Chaincode
Antimttr (Wed, 06 Mar 2019 17:17:32 GMT):
its allowed me to rapidly prototype, but no idemix so I'll have to start from scratch as far as the fabric services api
Antimttr (Wed, 06 Mar 2019 17:17:35 GMT):
w/java
Antimttr (Wed, 06 Mar 2019 17:18:13 GMT):
i was just hoping for some great examples on the java side similar to balance transfer
Antimttr (Wed, 06 Mar 2019 17:18:17 GMT):
but i guess that doesnt exist :/

rickr (Thu, 07 Mar 2019 13:01:10 GMT):
@anjalinaik According to our Gossip expert @yacovm, in docker-compose.yaml and peer-base.yaml the only things to be done is remove all `CORE_PEER_GOSSIP_ENDPOINT` and `CORE_PEER_GOSSIP_SKIPHANDSHAKE` lines .
Example of how to add anchor peers:
https://github.com/hyperledger/fabric-sdk-java/blob/dbc41c1a119f9567ec7b39d972663813c45e0d04/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java#L220-L249
yacovm (Thu, 07 Mar 2019 13:02:06 GMT):
Rick don't go around telling people I am expert on stuff :(
yacovm (Thu, 07 Mar 2019 13:02:28 GMT):
They will flood my private chats :rolling_eyes:
rickr (Thu, 07 Mar 2019 13:03:11 GMT):
Ok Don't @anjalinaik don't remove those lines .. I was mistaken he's not an expert! :rofl:
yacovm (Thu, 07 Mar 2019 13:03:28 GMT):
the `CORE_PEER_GOSSIP_ENDPOINT` is for overriding the internal endpoint that the peer reports to other peers
yacovm (Thu, 07 Mar 2019 13:03:36 GMT):
usually you don't need to use that at all
yacovm (Thu, 07 Mar 2019 13:04:07 GMT):
the only use case where you want to use it, is if you have a peer in docker inside a VM, and another peer in docker, in another VM, and they are all in the same org
yacovm (Thu, 07 Mar 2019 13:04:22 GMT):
in such a case- both peers would have internal endpoints that are not routable to one another
yacovm (Thu, 07 Mar 2019 13:04:38 GMT):
setting `CORE_PEER_GOSSIP_ENDPOINT` to be the VM's external interface solves this
yacovm (Thu, 07 Mar 2019 13:04:47 GMT):
because it overrides the internal endpoints they report to peers within their own org

But I'm getting this back:
```
"exceptionTrace" : "
com.mo.fabric.exception.FabricException: Not enough endorsers for invoke: createVerification. 2 endorser(s) returned with an error: Sending proposal to fabric-peer-org15-20654c failed because of: gRPC failure=Status{code=RESOURCE_EXHAUSTED, description=gRPC message exceeds maximum size 4194304: 4357851, cause=null}
```
Not really sure where this gRPC limit is set.
A few seconds of google finds this - https://stackoverflow.com/questions/39753730/java-grpc-how-to-increase-the-message-size-limit-in-a-managedchannel and this https://github.com/grpc/grpc-java/issues/4451 but I'm not sure if there's a property to increase this value this without searching through the codebase.
The only one I can see locally is grpc.NettyChannelBuilderOption.maxInboundMessageSize in the properties I create for NetworkConfig for the peers in my local test instance, but I'm not sure that's the correct value and even if it is, that doesn't help me when my production version is cloud hosted - I don't have access to edit the config (and nor imo should I be doing so).

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=sJhpfySNNC9gx5uTv) That's what I think I said I could set locally above.
My problem comes when the network properties are coming from another provider.
I don't think it's good practice for me to be editing their network configuration before trying to do a load from it.

Ok to flog my particular dead horse some more.
`grpc.NettyChannelBuilderOption.maxInboundMessageSize` is expected to be set in the properties for each of the peers/orderers et al.
It's propagated to the NettyChannelBuilder in Endpoint
Here's my problem. I call my "Enterprise Blockchain Network" provider for the NetworkConfig. It's passed back as a json payload which I coerce into a JsonObject (due to the NetworkConfig reqs).
This particular value isn't set.
Is there *really* an expectation that I go through the (multiple) JsonObjects returned - one per org - to find all of my peers/orderers and look for the properties - if there are any returned or create if not - in all of the network configurations for all of the orgs in this fabric and manually insert this value into every single one?

rickr (Tue, 12 Mar 2019 13:38:58 GMT):
Hmm -- maybe a disconnect in understanding. The link I provided showed that you could adjust the peer/ordererer properties before you create the channel from the neteworkconfig. 1) is that not what you want ? 2) is that not working ?
aatkddny (Tue, 12 Mar 2019 13:51:12 GMT):
The disconnect is this. This is our production blockchain network and it's hosted by a third party that's rather involved in same technology.
There are a number of orgs in it. We are proxying access to all of them on their behalf, so we get multiple network configurations.
I get the network configurations from this supplier by making calls for same.
It comes back as a series of json payloads. If you want the code it looks like this:
```
JsonReader reader = Json.createReader(new StringReader(json));
JsonObject jo = (JsonObject) reader.read();
org.setJo(jo);
return NetworkConfig.fromJsonObject(jo);
```
This then gets passed into the channel create code to do a loadFromNetworkObject. I don't touch it after I received it.
Yes I could go through each of these NetworkConfig objects and edit the properties associated with each peer and each orderer and inject this same value into every single one of the properties in there, but this seems like the wrong way to do this. My network is such that every peer has the potential to see the same size of message (the size that's set in configtx.yaml for max message size).
If it's set once there, it seems wrong for me to have to inject it all over the place because of a bad default in a builder. I'd expect to set a global variable and have that used.
As a more philosophical question, it also seems wrong to edit a network configuration returned from a third party network to accommodate an SDK. The whole idea (I thought) was to not have to manually build this configuration any more.

rickr (Tue, 12 Mar 2019 13:59:18 GMT):
This seems to me a very easy adjust. The common code point (function, method) where you load the network would do this adjustment. Your application could then have a *global* variable (yuck) to what it's set.
aatkddny (Tue, 12 Mar 2019 14:04:04 GMT):
The question isn't whether I can. Obviously I *can*. It's whether this is the *correct* way to do this.
There's exactly *one* maximum message size for an entire fabric network and it's set when the network is created. In this case I can't even see configtx so I'm forced to guess that they kept the default value.
I will now have to write code to edit the network definitions I get back from my provider just so I can set the same value - that can't change - in around 400 places.

rickr (Tue, 12 Mar 2019 14:43:25 GMT):
@aatkddny AFAIK there was no defined property in the netwrokconfig for max message size. Setting this is different for each SDK grpc. The networkconfig had a `grpc.keepalive_time_ms` which really Node based :( The JSDK does for that do the remap. There would need to be some agreement on how a grpc message size should be specified in the Networkconfig.
I'm not understanding why changing in 400 places - when a common method call by your application to loading a network could do that adjustment.

The 400 places is because I have a lot of nodes and a lot of channels.

Ok I added a ticket for same.
https://jira.hyperledger.org/browse/FAB-14605
In this case, the 400 places is a consequence of the node count and the way network config is returned. 400 places in the set of network configurations, not the code.

There's no "contract" that specifies max message size. irregardless of the SDK. The contract you speak of the NetworkConfig/Connection Profile as I said had no specification for setting that.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=gxLhmmAkJrf8RQpvX) But there *is* a contract between sdk and fabric.
A user shouldn't have to act as a man in the middle between these two because a required field is missing from that contract.
You either fix the contract or allow the user to pass in the field separately.

Not in any specific details so every SDK can implement uniformly and authors know what to set : nothing for the SDK to do
rickr (Wed, 13 Mar 2019 13:52:24 GMT):
Besides -- I don't think it's even right for that to be there. That document general purpose is for infrastructure providers to give to clients so they can easily construct the network with SDK of their choice to work with it. But as an infrastructure provider I have no idea what chaincode you will be deploying and what it's requirements are. Even as the chaincode author you may not know. One request may come in and produce just a few bytes of results to the client. Another request could produce 300MB.

Hi. while going through endorsement policy,
how do I get MSPID for IDENTITY/ANONYMITY of MSP Principal?
I'm not really sure how the identity/anonymity would work from User's perspective as well.
Currently I'm trying to decode the Endorsement Policy, but Identity/ANonymity of MSPPrincipal only has type value and nothing else, so I'm curious. Thanx!

Hi all
is there any difference between `HFCAClient.HFCA_TYPE_CLIENT` and `HFCAClient.HFCA_TYPE_USER`? from my observation, identities that are registered using these types are the same and they both behave like a common user
skarim (Thu, 14 Mar 2019 16:52:59 GMT):
The type of the identity ends up as an attribute in the certificate. You can then use cid library in chaincode to apply logic based on types if you'd like. Otherwise identities will behave the same.
gravity (Thu, 14 Mar 2019 17:18:30 GMT):
@skarim
got it, thanks
Antimttr (Thu, 14 Mar 2019 20:19:27 GMT):
hey @skarim ! you were responsible for writing idemix in the java sdk if i'm not mistaken?
skarim (Thu, 14 Mar 2019 21:13:00 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=6tPCYGrPBYEW8Crfh) @Antimttr I wrote the idemix end to end test case, but the actually java implementation was written by someone else
Antimttr (Thu, 14 Mar 2019 22:00:46 GMT):
@skarim ah nice, I have interest at my company to port the idemix from java to js. Right now im working on making a version of the balance transfer demo js api in java to get access to idemix
Antimttr (Thu, 14 Mar 2019 22:12:01 GMT):
In end2endIT.java theres a lot of references to SampleOrg, SampleStore, etc. So for a real implementation what data structure would these be replaced with?
Antimttr (Thu, 14 Mar 2019 22:12:10 GMT):
is there an Org and a Store class somewhere?
Antimttr (Thu, 14 Mar 2019 22:18:04 GMT):
seems like its just for staging test cases
Antimttr (Thu, 14 Mar 2019 22:18:39 GMT):
is there any non-test-case based java sdk example code anywhere?
Antimttr (Thu, 14 Mar 2019 22:19:04 GMT):
like from an actual implementation?

Antimttr (Fri, 15 Mar 2019 03:25:06 GMT):
@aatkddny ok interesting, thanks. I started with spring and it was horrifyingly complex, coming from like nodejs. I opted for jersey, way more straight forward, clean code imho
aatkddny (Fri, 15 Mar 2019 13:06:29 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=xMCxraAGa4grG2oNr) In this case the complexity is the logic, not the framework. The application I culled the user class from was custom written to build and instantiate any network from scratch (compose) or build (k8s) from a simple network definition file. It allows us to remove human error editing and submitting all the yaml files, and makes stopping and starting a fabric - something we've done a lot as we test - much quicker.
Antimttr (Fri, 15 Mar 2019 14:20:28 GMT):
@aatkddny I was just wondering what the business case was for storing all those records in perpetuity in a db? Is this to act as a backup for the ledger in case you need to rebuild corrupted data down the road?
aatkddny (Fri, 15 Mar 2019 14:22:06 GMT):
Well for the user you need to save the enrollment that the ca issues.
aatkddny (Fri, 15 Mar 2019 14:22:06 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=vTQJtPMs4N2QYZim7) @Antimttr We save the msp anchor tx - because we do them after we create the channel.
the channel.tx type records are used from disk when we create the channels, but we do that as part of creating the network.
Adding channels on the fly uses an external process.
Antimttr (Fri, 15 Mar 2019 14:22:31 GMT):
do you also save like the channel creation stuff?
Antimttr (Fri, 15 Mar 2019 14:26:40 GMT):
theres also a class they have called Sample store are you saving the data that fills up those objects?
Antimttr (Fri, 15 Mar 2019 14:28:39 GMT):
so the msp anchor is an artifact created by the use of idemix if im not mistaken?
aatkddny (Fri, 15 Mar 2019 14:31:11 GMT):
sample store is just a kv store. we save users, we load channels from a network configuration.
we have two flavors for this.
one that gets the config from our favorite blockchain service provider, and one that internally constructs a network config from our saved network properties for the stuff we have in our data center.

Antimttr (Fri, 15 Mar 2019 14:40:47 GMT):
So the configuration database is just referenced by your hyperledger management tools? (your sdk implementation)
Antimttr (Fri, 15 Mar 2019 14:41:47 GMT):

Can someone explain the below? IBM Blockchain Platform Starter (HLF 1.2): 2 Orgs, Org 1 has 1 Peer, Org 2 currently has no (zero) peers. Java SDK-based Client app uses an Org 1 user and peer, and registers persistent (i.e., outside of any transactional context) Block and Chaincode Event listeners (logged under "EventService" below) at startup and is logging every event they receive. A single transaction is sent to a simple chaincode that emits an "event1" event. The questions are
1. Why are the listeners seeing the same event repeatedly?
2. Why is the period varying?
3. Why are some blocks coming from peer "null" (Lines 3 and 5) which then stops?

Antimttr (Fri, 15 Mar 2019 14:47:16 GMT):
@aatkddny by maximum asset size you mean teh szie of any single ledger transaction? or do you mean the aggregate size of all transactions on the ledger?
aatkddny (Fri, 15 Mar 2019 14:49:47 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=ut35mcF6XeQ2vGZCQ) @Antimttr single tx - the size of the message sent to the orderer is bound.
Antimttr (Fri, 15 Mar 2019 14:50:01 GMT):
Is your UI that's slowing down tightly coupled with your SDK implementation, or are you making RESTful api calls to it from a web app?
aatkddny (Fri, 15 Mar 2019 14:50:28 GMT):
@dan13 - you get an event from each peer. there are two kinds - block and actual event. the payload differs between the two.
aatkddny (Fri, 15 Mar 2019 14:55:23 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=EkojxfnmoJvJMezzT) @Antimttr We have a dashboard. It aggregates sets of assets from more than one channel by invoking chaincode on each of the channels.
As asset count increases response time also goes up.
Yes yes I know - a blockchain is a lousy database, but until the work to fix it is scheduled this is what we have. To reduce asset count we were aggregating a specific set of periodic assets (daily metrics) into one uber asset. This hit a size limitation in our cloud instance.

Antimttr (Fri, 15 Mar 2019 14:56:52 GMT):
Ahh ok. Yeah our use case is a bit different so that (probably) wont be an issue. Our typical record size will be under 1kb and we'll only be doing a few hundred transactions a day (max). But its good to keep these things in mind
Antimttr (Fri, 15 Mar 2019 14:57:18 GMT):
Your dashboard. does it use synchronis or asynchronis calls to the hyperledger? also are you doing any caching of your hyperledger api calls?
aatkddny (Fri, 15 Mar 2019 15:00:22 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=oawJBfbiaGA3MaXgm) The calls into the fabric are async.
We self-synchronize so we can aggregate in the endpoint before it goes back to the browser. It'll get fixed when we put in something a bit more performant and the ui guys rejig the code to paginate.
Antimttr (Fri, 15 Mar 2019 15:01:49 GMT):
did you implement the pagination options in your hyperledger sdk implementation? I'm glad that they put that in there, atleast its in the node sdk
Antimttr (Fri, 15 Mar 2019 15:01:53 GMT):
hopefuly its also in the java sdk
dan13 (Fri, 15 Mar 2019 15:43:39 GMT):
@aatkddny Thanks -- the question is why am I receiving the same event -- block and chaincode -- multiple times. See the trace -- the peer is pushing the same data repeatedly.
dan13 (Fri, 15 Mar 2019 15:43:39 GMT):

aatkddny (Fri, 15 Mar 2019 15:45:22 GMT):
its not the same event. one is for the block one for each tx in the block. since default cut rate is 2s you are probably getting one of each.
dan13 (Fri, 15 Mar 2019 15:48:37 GMT):
@aatkddny see the log trace above. I have a block listener and a chaincode listener. 1 transaction occurred on the network with 1 peer. I would expect 1 block listener log (the block event), and 1 chaincode listener log (the chaincode event). I get multiple with the exact same payload (per type). It sounds like you are confirming my expectation, but that doesn't match the logs. In any event, if you are confirming my expectation, then I will research further - thanks
aatkddny (Fri, 15 Mar 2019 15:49:26 GMT):
you get an event for each peer on the channel iirc.
Antimttr (Fri, 15 Mar 2019 15:56:13 GMT):
@aatkddny do you also store this data structure in your database? https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric/sdkintegration/SampleOrg.java
Antimttr (Fri, 15 Mar 2019 15:57:43 GMT):
seems like some of this data would also reside in the network.yaml and orgX.yaml
Antimttr (Fri, 15 Mar 2019 15:58:23 GMT):
from the end2endIT file they load it using checkConfig(), so right from the config files
Antimttr (Fri, 15 Mar 2019 15:58:37 GMT):
so it would seem redundant to also store it in another db table
Antimttr (Fri, 15 Mar 2019 15:58:50 GMT):
but maybe you'd want to see all the iterations/revision of the data
aatkddny (Fri, 15 Mar 2019 16:07:55 GMT):
we do it differently. we have a very simple internal format config file that describes the network - orgs, number of peers and channel relationships.
we do everything from that.
everything as in run any crypto, run any configtxgens, generate the yaml files for docker or k8s and save what we need to allow us to build a networkconfig so we can do a channel.loadfromnetworkconfig when our real applications go to use this fabric. that's why we save stuff to the db - there's no redundancy for us. our implementation is different.

ok so basically
Antimttr (Fri, 15 Mar 2019 16:09:54 GMT):
you created your own configurator, which generates the logical hyperledger network configuration files
Antimttr (Fri, 15 Mar 2019 16:10:04 GMT):
does it also dynmically generate the docker-compose.yaml file?
aatkddny (Fri, 15 Mar 2019 16:10:11 GMT):
yes
Antimttr (Fri, 15 Mar 2019 16:10:25 GMT):
yeah i was thinking about making one of those for my administration gateway
aatkddny (Fri, 15 Mar 2019 16:11:39 GMT):
well ours has a switch - it'll do either compose or kubernetes. when you scale out more orgs compose falls flat. swarm isn't well supported so you end up moving (painfully in my case) to kubernetes.
Antimttr (Fri, 15 Mar 2019 16:11:59 GMT):
oh really?
Antimttr (Fri, 15 Mar 2019 16:12:12 GMT):
how many orgs did it take to get to that point?
Antimttr (Fri, 15 Mar 2019 16:12:21 GMT):
(and how many peers?)
Antimttr (Fri, 15 Mar 2019 16:12:57 GMT):
also were all these running on a single host server?
Antimttr (Fri, 15 Mar 2019 16:13:05 GMT):
or do you have them spread out amongst multiple servers?
Antimttr (Fri, 15 Mar 2019 16:13:34 GMT):
are the kubernetes images rolled for us like the docker images are?
Antimttr (Fri, 15 Mar 2019 16:13:38 GMT):
like by the hyperledger folks
Antimttr (Fri, 15 Mar 2019 16:13:43 GMT):
or did you have to roll your own?
Antimttr (Fri, 15 Mar 2019 16:14:17 GMT):
or can you use the docker images with kubernetes?
Antimttr (Fri, 15 Mar 2019 16:26:53 GMT):
it seems like you can
aatkddny (Fri, 15 Mar 2019 16:29:17 GMT):
we tapped out at about 8 two node orgs in docker. compose was single docker and single large server.
when we started this there were no kubernetes images - it was all roll your own. there are some published now that use helm charts so that'll make it easier, but there's still no tls in any of them.
aatkddny (Fri, 15 Mar 2019 16:29:17 GMT):

Antimttr (Fri, 15 Mar 2019 16:30:13 GMT):
so you rolled your own to get around that limitation?
aatkddny (Fri, 15 Mar 2019 16:30:26 GMT):
yes. we autogen all the files.
aatkddny (Fri, 15 Mar 2019 16:30:26 GMT):
yes. we autogen all the files from the config
Antimttr (Fri, 15 Mar 2019 16:31:21 GMT):
are you able to just modify the existing not tls images, or you have to completely start from scratch?

PradeepJaligama (Fri, 15 Mar 2019 16:33:15 GMT):
there is also something called as network launcher that supports a wide variety of options..
Antimttr (Fri, 15 Mar 2019 16:33:31 GMT):
is that in kubernetes?
PradeepJaligama (Fri, 15 Mar 2019 16:34:05 GMT):
i dont think so
PradeepJaligama (Fri, 15 Mar 2019 16:34:11 GMT):
but could be useful for local deployments

Antimttr (Fri, 15 Mar 2019 16:35:37 GMT):
says it is using codebase v1.0.0, i guess it hasnt been updated for 1.4? or does it work regardless of subversion?
aatkddny (Fri, 15 Mar 2019 16:38:14 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=oncL5AuzDmNMY5FLK) @Antimttr We started from scratch. the images didn't exist when we started this project.
Antimttr (Fri, 15 Mar 2019 16:39:01 GMT):
i wonder if theres any hyperledger docs that discuss rolling your own peer/orderer/ca nodes
Antimttr (Fri, 15 Mar 2019 16:39:13 GMT):
i've never rolled my own docker image before
aatkddny (Fri, 15 Mar 2019 16:40:24 GMT):

ya, NL is not really updated since 1.0
Antimttr (Fri, 15 Mar 2019 16:48:07 GMT):
@aatkddny thanks for the info! im checking out this now: https://kubernetes.io/docs/tutorials/configuration/configure-redis-using-configmap/ seems like this would be a good scalable solution
Antimttr (Fri, 15 Mar 2019 16:48:41 GMT):
how many orgs are you working with now on your kubernetes setup?
aatkddny (Fri, 15 Mar 2019 17:39:19 GMT):
more than 20
aatkddny (Fri, 15 Mar 2019 17:42:09 GMT):
tbh if i was starting from scratch i'd look at adapting the hlf- stuff in here https://github.com/helm/charts/tree/master/stable

Anyone hit and figure a workaround for this? `HFCAClient url does not support path portion in url remove path`
Trying to put an ingress on my CA in k8s and need to use paths - have a bunch of endpoints that I need to differentiate between.

With a path and a little rewrite voodoo something like this `http://localhost/firstca/api/v1/cainfo` becomes valid and I'm not restricted to defining NodePorts all over the place.

Hi all
are there any critical reasons why JSDK does not have a method to fetch a single identity from a CA server but have a method to fetch a collection of identities by registrar?
as I can see, fabric ca has an endpoint to fetch an identity by its enrollment id

hi all
Have anyone tried to update `channel_group.groups.Application.groups.ORG_NAME.values.MSP.value.config.revocation_list` using the java sdk?
The way I've prepared a channel updated is the same compared to this test:
https://github.com/hyperledger/fabric-sdk-java/blob/release-1.4/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java
but, I've revoked a user with flag `genCRL:true` and put a returned string to the `channel_group.groups.Application.groups.ORG_NAME.values.MSP.value.config.revocation_list`, signed a transaction using the peer admin identity and sent a transactions
I've tried to do so, but getting the error:

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=NqhdukQ42tMNThuJT) @rickr if you have any quick thoughts about this issue (probably some concept I'm missing?) it would be much appreciated!
Antimttr (Tue, 19 Mar 2019 18:09:28 GMT):
In the java sdk's TestConfig.java file there are some default properties that get loaded: ```
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.mspid", "Org1MSP");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.domname", "org1.example.com");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.ca_location", "http://" + LOCALHOST + ":7054");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.caName", "ca0");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.peer_locations", "peer0.org1.example.com@grpc://" + LOCALHOST + ":7051, peer1.org1.example.com@grpc://" + LOCALHOST + ":7056");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.orderer_locations", "orderer.example.com@grpc://" + LOCALHOST + ":7050");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.mspid", "Org2MSP");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.domname", "org2.example.com");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.ca_location", "http://" + LOCALHOST + ":8054");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.peer_locations", "peer0.org2.example.com@grpc://" + LOCALHOST + ":8051,peer1.org2.example.com@grpc://" + LOCALHOST + ":8056");
defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg2.orderer_locations", "orderer.example.com@grpc://" + LOCALHOST + ":7050");
```
Antimttr (Tue, 19 Mar 2019 18:09:42 GMT):
Which of the configuration artifacts are these defaults replacing?
Antimttr (Tue, 19 Mar 2019 18:10:50 GMT):
the keys set dont seem to quite match any of the artifacts i've found so far, (like docker-compose.yaml, network-config.yaml, orgX.yaml
dan13 (Tue, 19 Mar 2019 18:24:05 GMT):
@Antimttr as I read it it is setting default JSDK network config values (values used to connect from java client to network) regardless of anything else (it's in a finally block)
Antimttr (Tue, 19 Mar 2019 18:24:33 GMT):
well yeah, but it first tries to read it from a file
Antimttr (Tue, 19 Mar 2019 18:24:44 GMT):
i was just wondering what configuration artifact that file corresponds to
Antimttr (Tue, 19 Mar 2019 18:25:29 GMT):
maybe its config.properties
Antimttr (Tue, 19 Mar 2019 18:25:40 GMT):
but this was a bit confusing because that file is totally commented out
Antimttr (Tue, 19 Mar 2019 18:26:30 GMT):
well thats in the Config.java anyways
Antimttr (Tue, 19 Mar 2019 18:26:41 GMT):
in TestConfig it tries to load testutils.properties
Antimttr (Tue, 19 Mar 2019 18:27:19 GMT):
Which doesnt exist in the repo i dled anywhere
Antimttr (Tue, 19 Mar 2019 18:28:15 GMT):
i would think in an actual implementation of the java sdk you'd want to read from actual configuration artifacts
Antimttr (Tue, 19 Mar 2019 18:28:32 GMT):
but the keys dont quite correspond to any of the keys in a real config file
Antimttr (Tue, 19 Mar 2019 18:28:45 GMT):
for instance: `defaultProperty(INTEGRATIONTESTS_ORG + "peerOrg1.ca_location", "http://" + LOCALHOST + ":7054");`
Antimttr (Tue, 19 Mar 2019 18:29:01 GMT):
ca_location i can only find references to in this TestConfig.java file
Antimttr (Tue, 19 Mar 2019 18:29:22 GMT):
doesnt seem to be an actual property from any configuration artifact
Antimttr (Tue, 19 Mar 2019 18:31:07 GMT):
vs something like the *network-config.yaml* file from balance-transfer demo contains keys like: ```
certificateAuthorities:
ca-org1:
url: https://localhost:7054
# the properties specified under this object are passed to the 'http' client verbatim when
# making the request to the Fabric-CA server
httpOptions:
verify: false
tlsCACerts:
path: artifacts/channel/crypto-config/peerOrganizations/org1.example.com/ca/ca.org1.example.com-cert.pem
```
Antimttr (Tue, 19 Mar 2019 18:31:39 GMT):
does ca_location get translated to one of these values at some point?
Antimttr (Tue, 19 Mar 2019 18:31:58 GMT):
the logical one would be url
Antimttr (Tue, 19 Mar 2019 18:32:14 GMT):
but nothing in the sdk docs really indicates that this is the case
Antimttr (Tue, 19 Mar 2019 18:38:41 GMT):
or are these special kinds of configuration files
Antimttr (Tue, 19 Mar 2019 18:38:45 GMT):
that are specific to the java sdk?
Antimttr (Tue, 19 Mar 2019 18:39:03 GMT):
if so can they be extrapolated out of the normal configuration artifacts?
Antimttr (Tue, 19 Mar 2019 18:39:10 GMT):
if they can, is there already a tool to do so?
Antimttr (Tue, 19 Mar 2019 18:46:34 GMT):
like NetworkConfig.java seems to do that for the network-config.yaml
Antimttr (Tue, 19 Mar 2019 19:28:40 GMT):
@rickr SHOULD the java sdk implementation load configuration data from the traditional artifacts or should it implement its own configuration data like the End2EndIT test does?
Antimttr (Tue, 19 Mar 2019 19:29:01 GMT):
to compare I dont really see this behavior in the other SDKs
Antimttr (Tue, 19 Mar 2019 19:29:05 GMT):
seems to be a java thing
Antimttr (Tue, 19 Mar 2019 19:29:24 GMT):
but its not clear why the difference exists
Antimttr (Tue, 19 Mar 2019 19:55:28 GMT):
https://github.com/IBM/blockchain-application-using-fabric-java-sdk
Antimttr (Tue, 19 Mar 2019 19:55:37 GMT):
hadnt seen this yet
Antimttr (Tue, 19 Mar 2019 19:55:53 GMT):
its for an old version but atleast it gives clues on how to implement the client from the sdk
rickr (Tue, 19 Mar 2019 21:33:34 GMT):
@dan13 Not sure but what version are you using of the SDK and Eventbubs are no longer supported
rickr (Tue, 19 Mar 2019 21:41:18 GMT):
@Antimttr none of the Sample or TestConfig are part of the SDK.
https://github.com/cr22rc/fabricSDKJavaMultiDomainSample/blob/master/src/main/java/org/cr22rc/MultiDomainSample.java
that's old but maybe it can help you.
The `network-config.yaml` and NetworkConfigIT sample does the reconstructinon of the channel and CA as defined by that file.

Hi anyone knows an example of java sdk which it is implemented on kubernetes? i only found https://github.com/IBM/blockchain-application-using-fabric-java-sdk and it doesnt work for me ):
dan13 (Wed, 20 Mar 2019 14:41:50 GMT):
@rickr Sorry - HLF 1.2 (IBP Starter -- not the new v2 beta), and registration occurs via:
String eventListenerHandle = channel.registerChaincodeEventListener(Pattern.compile(".*"), Pattern.compile(Pattern.quote(eventName)), chaincodeEventListener);
This is the new way of registering, correct?
rickr (Wed, 20 Mar 2019 15:07:33 GMT):
@dan13 Not really sure there are cases where the peer eventing service reconnects (due to network issue or peer start/stops) that it could get the block again and this would happen.
rickr (Wed, 20 Mar 2019 15:08:40 GMT):
The peer = null is really odd. You could enable the SDK trace that may give some more insight ( what version of the sdk ? )
dan13 (Wed, 20 Mar 2019 15:37:43 GMT):
@rickr Thanks. fabric-sdk-java version is 1.2.1. Even after a couple days, restarting the client app resulted in the same repeated events (both block and chaincode) ad infinitum for the last block on the ledger. Theoretically any listener app needs duplicate rejection anyway if it has multiple peer event sources for the same channel (if I understand correctly).

@rickr https://ctrlv.it/id/168656/1503245437 -- I'm guessing this is the log of the cause? What is root cause, if known for this error?

rickr (Wed, 20 Mar 2019 16:50:06 GMT):
Yeah we just faithfully reprocess the block. You'd need to probably look at the peer logs see if something is going on there.
Given it's probably behind a proxy (IBM BC) you may want to add this if you haven't done so ->

httpOptions:
verify: false
```
Antimttr (Wed, 27 Mar 2019 14:40:16 GMT):
how can i apply this option to the java sdk's HFCAClient? Right now im getting an error that the host name doesnt match the certificate name

i'm assuming this option is what disables that check
Antimttr (Wed, 27 Mar 2019 14:40:45 GMT):
but im unsure about where to apply the setting, should it go into the properties that i pass into the contructor fo the hfcaclient?

When sending a transaction, I see that there are options to select specific orderers.
Does it make it more efficient(and maybe faster) to specify specific orderers when we are using multiple orderers/kafka/zookeeper?
I thought kafka/zookeeper would do all the even distribution.
MHBauer (Thu, 28 Mar 2019 03:28:01 GMT):
Has left the channel.
rickr (Thu, 28 Mar 2019 12:40:48 GMT):
Allowing you to defined multiple orderers just lets the SDK provide mostly a simple fail over if one can't be connected. There is a _simplistic_ balancing by just picking a random one to start with. However the application should be allowed to select which orderer it really wants.
gravity (Thu, 28 Mar 2019 13:14:22 GMT):

aatkddny (Thu, 28 Mar 2019 14:34:55 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=ZEkq2RWBqfsqdo8fd) Unless I completely misunderstood the question, you can attach peers to multiple channels for sure - we do it since we have a lot of channels - but you need a different channel object for each.
Caching the HFClient and the Channel objects speeds the whole process up significantly.
Of course you still have to read each channel separately, but you'd expect that from the way channels are implemented.
aatkddny (Thu, 28 Mar 2019 14:38:13 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=DXbjs6yLbG64NAK8b) You need to adjust the block cut rate and maximum message count in config.tx first.
When you tune that to your liking you'll hit the issue with threading that netty has and that'll limit you. We started failing in triple digits /s iirc, but our tx rate for the one project we care about is significantly lower. I'll search for the post about the threading issue in a minute or two. It's back in here last year somewhere

@rickr Thanks for the answer...I do have one more Q....
Is it possible to have the 2 responses of response.getChaincodeActionResponsePayload() same but get SDKUtil.getProposalConsistencySets != 1??
Few times, I do get this error and the Chaincode does not take any time-related input.
I thought since SDKUtil.getProposalConsistencySets() check for proposalResponse.getPayload(), it could be different from getChaincodeActionResponsePayload(). But I'm not really sure how that could be the case.
Could you give a hint?

@rickr @aatkddny the original question was the next: is it recommended to have peers that serve requests only for a specific channel (peer0 and peer1 join channel0 and peer2 and peer3 join channel1)? or should it be better to join all peers(peer0, peer1, peer2, peer3) to all channels (channel0, channel1) and these peers will be serving requests for these channels?
and there is one more question: if I have four peers (peer0-3) that are joined to channels multiple channels (channel0, channel1), these peers have the same chaincode installed (with the same version) and this chaincode is instantiated on both channels (channel0, channel1), will this setup work without any conflicts between chaincodes on these channels?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=HvtY4qarwKYLqCD6j) Q1 - doesn't it depend on the endorsement policy, and whether the peers need access to the data on the channel.
We for example have a bunch of contracts between pairs of orgs that must remain private only to that pair, so (say) Org1 and Org2 are parties on one channel and Org2 and Org 3 on another. Org 2 can see everything, Orgs1 and 3 can only see "their" data. Yes you can do that with a permissioned channel, but not if you can't allow Org 1 to know that Org3 is also transacting with Org2.
Q2 - it works fine. Or it does for at least as far as we tested it (multiple 10's of channels in a peer). The one caveat is that we always upgrade everything at once. Rolling updates haven't been tested.

Hello at All!
I have one question to ask.
I have a blockchain network fabric 1.4 customized with 3 Peer in one Organization with 3 CouchDB and 1 CA( MSP).
I have a Java SDK Client to connenct to blockchain network and invoke, query a chaincode and register and enroll new user.
But when I Connect with Admin Peer User, all query and invoke it works properly.
But when I Connect with a new User, registered and enrolled, I can't to do a Query Or Invoke because I have this message error:

I pass to HFCLient the User lucaclient and then invoke the chaincode

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=eojhbHw62NDJktvck) @aatkddny there is no need in caching channel objects. once it's initialized using HFClient, the latter holds a reference to a channel in a hashmap. the same is for HFClient - as long as a single instance of HFClient is enough, it can be created during application startup and reuse this object for every transaction by setting a user context directly to a transaction context. @rickr please correct me if I'm wrong

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=rw4o4bG8M8i4R97Dn) Your turnaround time is based on the block cut rate.
These 3 values in config.tx can be used to tune it. Reduce batch timeout and increase batch size.
```
# Batch Timeout: The amount of time to wait before creating a batch.
BatchTimeout: 2s
# Batch Size: Controls the number of messages batched into a block.
# The orderer views messages opaquely, but typically, messages may
# be considered to be Fabric transactions. The 'batch' is the group
# of messages in the 'data' field of the block. Blocks will be a few kb
# larger than the batch size, when signatures, hashes, and other metadata
# is applied.
BatchSize:
# Max Message Count: The maximum number of messages to permit in a
# batch. No block will contain more than this number of messages.
MaxMessageCount: 10
# Absolute Max Bytes: The absolute maximum number of bytes allowed for
# the serialized messages in a batch. The maximum block size is this value
# plus the size of the associated metadata (usually a few KB depending
# upon the size of the signing identities). Any transaction larger than
# this value will be rejected by ordering. If the "kafka" OrdererType is
# selected, set 'message.max.bytes' and 'replica.fetch.max.bytes' on
# the Kafka brokers to a value that is larger than this one.
AbsoluteMaxBytes: 10 MB
# Preferred Max Bytes: The preferred maximum number of bytes allowed
# for the serialized messages in a batch. Roughly, this field may be considered
# the best effort maximum size of a batch. A batch will fill with messages
# until this size is reached (or the max message count, or batch timeout is
# exceeded). If adding a new message to the batch would cause the batch to
# exceed the preferred max bytes, then the current batch is closed and written
# to a block, and a new batch containing the new message is created. If a
# message larger than the preferred max bytes is received, then its batch
# will contain only that message. Because messages may be larger than
# preferred max bytes (up to AbsoluteMaxBytes), some batches may exceed
# the preferred max bytes, but will always contain exactly one transaction.
PreferredMaxBytes: 512 KB
```

@aatkddny I've tried to set timeout to 1s and diferent values(30, 50, 100, 250, 300) for max-message-count, but it did not help. the higher batchsize, the lower throughput. for testing purposes I've used JMeter with 50, 75, 100, 120 threads and Constant Throughput Timer was set to 1000 tps. the resulting tps was as I said 100-170 TPS. trandactions were sent to a single channel that has 4 peers (two of them are endorsers), all peers from the same org. the endorsement polucy is `OR("ORG1.peer")`
sandy (Tue, 02 Apr 2019 07:17:04 GMT):
hi.. As all the peers of the same channel has same ledger why we are getting endorsements from all the peers ?
Is there any possibility of ledgers in the different peers of the same channel to be different?
gravity (Tue, 02 Apr 2019 07:43:59 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=jr9n9SkHf59jqoRDr) @sandy for example, you can change the data in peers world state database and in this case your peers can have different data sets, hence endorsement can fail
sandy (Tue, 02 Apr 2019 07:47:05 GMT):
@gravity why would someone changes the data in their peer? is there any use case to modify the peer data?
dave.enyeart (Tue, 02 Apr 2019 10:49:46 GMT):
No, there is no use case to modify peer data, if you do so you are essentially corrupting your own peer. Endorsements of that data on the peer will fail and the other members of the channel may ostracize you.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=Djaf8M6WGra72M2g6) @aatkddny Can you clarify? Does this mean that your single client app/service makes calls on behalf of multiple Orgs, and that the method by which you are doing that is to have a singular HFClient per Org within the app (e.g., a shared Map where String is Org ID), and based on the specific requester (or other key data) the related HFClient is used?
aatkddny (Tue, 02 Apr 2019 14:24:15 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=PetDnoShZLSNnYTej) @dan13 Yes. Multiple orgs. One HFClient per org (per calling instance). We swap in the actual user or admin as required into the user context to make the calls.
aatkddny (Tue, 02 Apr 2019 14:24:15 GMT):

We swap in the actual user or admin as required into the user context to make the calls. We don't have enough volume to worry about collisions - iirc it's thread safe after dispatch, so it's mostly in our app.
gravity (Tue, 02 Apr 2019 14:34:03 GMT):
@aatkddny Hi
How do initialize channel? From what I see, HFClient should have user context to initialize a channel correctly. But in this case the user context must be set directly to the HFClient and this makes it hard to reuse
dan13 (Tue, 02 Apr 2019 14:41:18 GMT):
@aatkddny Thank you! Can you explain "We don't have enough volume to worry about collisions - iirc it's thread safe after dispatch, so it's mostly in our app" -- where would those collisions possibly occur? I assume you build a TransactionProposalRequest applying the request-specific user context using setUserContext() and then use the matching HFClient/Channel to send the proposal and then transaction. All of that should be completely safe, right? @gravity I was told here earlier that there is no problem initializing HFClient with user A from Org 1 and then transacting with different users from Org 1 (by setting on proposal) -- is your experience different?
gravity (Tue, 02 Apr 2019 14:49:03 GMT):

@gravity sync (get) at the moment. are you using async, and if so, did you switch from sync?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=mxZvaKQ73GBHMGKgw) HFClient isn't synchronized in our app. We could (in theory) get something that overwrites the user context if we had two in flight transactions before it was sent to sdk.

Is there a way to store enrollment information in a db and reconstitute it into an Enrollment object?
gravity (Tue, 02 Apr 2019 20:20:08 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=dGRnQTJzgvJu9m6kW) @dan13 well, I'm going to. what I see now in our app, synchronous way of transaction processing holds a lot of resources while waiting for the future to complete. for example, if I receive a request from the front end to issue a transaction for a particular user, I should fetch an enrollment object from the database for this user, then send send a proposal, send a transaction and wait for it to complete. and if if I understand correctly, all these actions happen in the same thread. also, as long as we send a request to a database from this thread, the latter can hold a thread (taken from the db connection pool). that means that a db thread is also blocked by synchronous call to `get()` or `join()` and you have have high transaction arrival rate, the db connection pool will be exhausted and a connection to a database will be lost. that is my observation. please correct me if I'm wrong
Antimttr (Tue, 02 Apr 2019 20:35:52 GMT):
@Antimttr was able to generate the enrollment object by using a pem->Keypair function i found on SO: ```
public static KeyPair keyToValue(String pkcs8key) {
Reader rdr = new StringReader(pkcs8key);
KeyPair pair = null;
try {
Object parsed = new org.bouncycastle.openssl.PEMParser(rdr).readObject();
pair = new org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter().getKeyPair((org.bouncycastle.openssl.PEMKeyPair) parsed);
} catch(Exception e) {
System.out.println("ERROR: Unable to generate enrollment: " + e.getMessage());
e.printStackTrace();
return null;
}
return pair;
}
}
```

gravity (Wed, 03 Apr 2019 06:40:09 GMT):
@Antimttr and when you want to use an Enrollment object, fetch encrypted hex from db, decrypt it, decode from hex string to byte[] and deserialize using the same Kryo lib

Antimttr (Wed, 03 Apr 2019 22:07:41 GMT):
Also, do i need a separate specific peerAdmin like they use in end2endIT, or can you use the org Admin to act as the peerAdmin? What is the point of having one admin do peer stuff and the other admin be the org admin?
rickr (Wed, 03 Apr 2019 23:39:57 GMT):
In general I don't see a wide use case for have more than one client .. if any.
As for those setting try reading the README.md end2end :) .. should be pointers in there.
Your application could create as many user it likes. There are basically four general types of users used by the sdk. There is orderer admin that can create the channel and update it like adding new organizations. There is a peerAdmin that can join organizations peers to the channel, deploy chaincode to the channel etc. There is an admin for the CA that we should IMO have named registrar that can register new regular users who then enroll to get their certificate/keys. Regular user can as the SDK is setup just invoke and query chaincode. There a lot of configuration that can be changed on both CA and Peers, Orderers (Fabric) that could change that. It's not for every SDK to document that. See the fabric documentation

@Antimttr By chance are you going through some proxy/firewall. If yes, look at the README.md FAQ for properties you may need to set
Antimttr (Fri, 05 Apr 2019 19:30:11 GMT):
Yeah I read about that. I am not but I'm just in a dev environment at this point. There's certainly a possibility that someone running the client could go through firewalls
Antimttr (Fri, 05 Apr 2019 19:31:23 GMT):

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=MPGmQAfyyM8ndEkEv) I think it gets encoded into the channel genesis block from configtx.yaml - from the ChannelDefaults under Admins, no? So the default would be majority.

I may be dead wrong - we sorta cheat as I have access to *all* the channel member organization's peer admins.
I just build an array of all the `getChannelConfigurationSignature` results for all of them, so I never really have to think about it.

@adamhardie In general, the future is not done when sent to orderer. It gets completed when all eventing peers have seen the block with the transaction. Which means on those peers the transaction is on the ledger.

Or the orderer is unable to tell the committer that the block has been successfully pushed to the eventing peer

@SandySun2000 The sdk has little to do but send the update to fabric. The fact that it worked the second time and I have not heard any reported issue with the SDK doing updates makes me doubtful anything is wrong with was sent. The only way to know for sure is capture the issue with logging at debug both sdks and fabric. Then since the rejection is by the commiting peer and the SDK is just reporting it you would need to start them looking at it.

I just got channel creation working in my client implemenation. However there's a small issue. I am checking to see if the channel already exists by calling HFClient.getChannel(name), and this works fine as long as i dont restart the client. if i do this comes up empty, even though a channel exists on the hyperledger. so my question is how can i load the channel state from the hyperledger into the sdk client so this doesn't happen?
Antimttr (Wed, 10 Apr 2019 22:36:33 GMT):
OK so i solved it by serializing the channel after its created, storing it in mongo and then loading it up back into the HFClient after reloading my client.

Antimttr (Thu, 11 Apr 2019 14:57:01 GMT):
am i just missing it or is that not a thing with the java sdk?
Antimttr (Thu, 11 Apr 2019 14:57:27 GMT):
that operation would use the /artifacts/channel/Org1MSPanchors.tx file
rickr (Thu, 11 Apr 2019 15:45:23 GMT):
Updating the channel example is provided... again (re)- look over the readme.md
Antimttr (Thu, 11 Apr 2019 16:02:19 GMT):
can't find any mention of anchor peers in the readme
Antimttr (Thu, 11 Apr 2019 16:02:41 GMT):
only normal peers
Antimttr (Thu, 11 Apr 2019 16:02:44 GMT):
which i'm already writing
Antimttr (Thu, 11 Apr 2019 16:04:15 GMT):
@rickr near as i can tell constructChannel() instantiates the orderers, creates the channel and then adds regular peers, no mention of anchor peers
Antimttr (Thu, 11 Apr 2019 16:04:30 GMT):
infact I cant even find any use of the word anchor in the readme or in end2endIT
Antimttr (Thu, 11 Apr 2019 16:05:09 GMT):
that's why i was wondering if this is even a part of the java sdk implementation
Antimttr (Thu, 11 Apr 2019 16:06:05 GMT):
likewise, I can't find any equivilent of the channel.initialize() sdk call in the nodejs implementation
Antimttr (Thu, 11 Apr 2019 16:06:25 GMT):
but it seems that the initialize() call can only be made after peers have been added
Antimttr (Thu, 11 Apr 2019 16:21:44 GMT):
@rickr so i did find mention of anchor peers in https://github.com/hyperledger/fabric-sdk-java/blob/8044bac1bfe9baf9d6360b067e0d6b5445cc953d/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java

if only there was a more up to date example
Antimttr (Fri, 12 Apr 2019 02:18:38 GMT):
like do i really need to update the anchors like the nodejs sdk does
Antimttr (Fri, 12 Apr 2019 02:18:41 GMT):
not sure
Antimttr (Fri, 12 Apr 2019 02:24:32 GMT):
seems pretty straight forward updating the anchor peers by the command line, but the java example has all this code testing out the sdk so its hard to pull out from that what i actually need to execute to do it
Antimttr (Fri, 12 Apr 2019 02:26:18 GMT):
what's even more confusing is than in https://github.com/hyperledger/fabric-sdk-java/blob/d2bc6d50e362a140970a509ade25f2f2c69e6c0f/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java there's not really any reference to the configtxgen generated file Org1MSPanchors.tx which both the nodejs sdk implementation and the command line use

what's even more confusing is that in https://github.com/hyperledger/fabric-sdk-java/blob/d2bc6d50e362a140970a509ade25f2f2c69e6c0f/src/test/java/org/hyperledger/fabric/sdkintegration/UpdateChannelIT.java there's not really any reference to the configtxgen generated file Org1MSPanchors.tx which both the nodejs sdk implementation and the command line use
Antimttr (Fri, 12 Apr 2019 02:26:25 GMT):
but maybe its burried in some helper funciton somewhere
Antimttr (Fri, 12 Apr 2019 14:34:22 GMT):
In updateChannelIT.java: ```
String responseAsString = configTxlatorDecode(httpclient, channelConfigurationBytes);
```
Antimttr (Fri, 12 Apr 2019 14:34:40 GMT):
is this the same as an `Org1MSPanchors.tx"` ?
Antimttr (Fri, 12 Apr 2019 14:36:58 GMT):
i guess im confused but it seems like this updatechannelit deal doesn't actually add anchor peers to the channel
Antimttr (Fri, 12 Apr 2019 15:09:04 GMT):
having reviewed the code from updatechannelit and the channel.java from the sdk once again i think i found what i need: ```
// Get config update for adding an anchor peer.
Channel.AnchorPeersConfigUpdateResult configUpdateAnchorPeers = fooChannel.getConfigUpdateAnchorPeers(fooChannel.getPeers().iterator().next(), sampleOrg.getPeerAdmin(),
Arrays.asList(PEER_0_ORG_1_EXAMPLE_COM_7051), null);
//Now add anchor peer to channel configuration.
fooChannel.updateChannelConfiguration(configUpdateAnchorPeers.getUpdateChannelConfiguration(),
client.getUpdateChannelConfigurationSignature(configUpdateAnchorPeers.getUpdateChannelConfiguration(), sampleOrg.getPeerAdmin()));
```
Antimttr (Fri, 12 Apr 2019 15:09:31 GMT):
near as i can tell this will add t he anchor and update the channel with the new configuration block
Antimttr (Fri, 12 Apr 2019 15:10:58 GMT):
Apparently you dont use, or don't need to use a 'Org1MSPanchors.tx' to do this, unlike in the other sdk examples?
Antimttr (Fri, 12 Apr 2019 15:11:00 GMT):
dunno
Antimttr (Fri, 12 Apr 2019 15:28:12 GMT):
so in the updatechannelit.java, it uses the format: "peer0.org1.example.com:7051" to tell the sdk what anchor peer to add. my question is, does the address have to be that of the physical listener, ie: localhost:7051 or can it be the name of the peer?
Antimttr (Fri, 12 Apr 2019 15:28:35 GMT):
i'm guessing its the latter, but how does it reconsile the peer name to the physical address/url?
Antimttr (Fri, 12 Apr 2019 15:28:35 GMT):
i'm guessing its the latter, but how does it resolve the peer name to the physical address/url?
Antimttr (Fri, 12 Apr 2019 19:50:21 GMT):
that was in fact the way to do it

bilalahmed (Mon, 15 Apr 2019 14:10:13 GMT):
Okay, thanks a lot. Will follow your suggestions. To learn JAVA SDK should we start from unit tests and learn from code or is there any documentation for the development and deployment of chaincodes using JAVA SDK?
rickr (Mon, 15 Apr 2019 14:12:27 GMT):
As it says -- you should have some basic of fabric behind your belt. The integratons tests do 95% of what any application will do the sdk. Mostly just follow what's in those files ignore most of that's happening the the Sample stuff as that's not really part of the SDK
bilalahmed (Mon, 15 Apr 2019 14:16:08 GMT):

Hello, Can anyone please guide that how can we pass peer/orderers certificates in JAVA SDK while playing with grpcs when TLS is enabled. Thanks

What is the use of EndPoint class in this context?
rickr (Thu, 18 Apr 2019 12:12:37 GMT):
@bilalahmed EndPoint is internal to the SDK not public. The READEM.md states how the Integration test can be run with TLS enabled so you can follow that. https://sdkjavadocs.github.io/org/hyperledger/fabric/sdk/HFClient.html newPeer newOrderer methods have explanation of the properties. You could have seen these being used in https://github.com/hyperledger/fabric-sdk-java/blob/df422e10fa38bf8a627dd81e7ad038404d625576/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java#L813-L824
and a few lines below that for the Peer. Take the time read the README.md follow the integration tests step for step :wink:

bilalahmed (Thu, 18 Apr 2019 13:19:09 GMT):
One suggestion: Not everyone use the same names of peer/orderers/ca etc. to build network setup which are being used the tutorials. Like I did, I gave my names to peers/orderers organisations etc. So, I can't use the provided SDK intergations. So, It would have been a much better approach that proper documentation is provided instead of taking SDK understanding from code. I'll write a detailed documentation on JAVA SDK once I cross all the hurdles.
Antimttr (Thu, 18 Apr 2019 13:25:10 GMT):
@chill37 its in End2EndIT.java towards the end after runtests
rickr (Thu, 18 Apr 2019 14:17:45 GMT):
@bilalahmed Don't understand your suggestion on the names. You can walk step for step in a debugger through the integration test that show the api in *action* and in context. You *know* the code is current and because the test actually are passing it's not stale like I've seen many _tutorials_ go. If you've taken some time and familiarized yourself with those examples writing your application is really a matter of copy/paste/modify.
Antimttr (Thu, 18 Apr 2019 15:02:41 GMT):
thats what i did, and although I wouldn't say it was easy. I was able to make a completely functioning POC client by extracting the relevant bits from the end2endit files

@rickr yes. when I used channel.queryByChaincode() instead of channel.sendProposalToEndorsers() using all peers, it worked successfully.
when I did some digging, I found out that, sdChaincodeMap outputs null when called from sendProposalToEndorsers()

Initially, when called from channel.initialize(), it has the full map but when called from sendProposal() it somehow outputs null.
do you have any other suggestions? I was looking at this this whole 2 days, but haven't got any answers yet.....any ideas I appreciate it.
@yacovm unfortunately, I'm trying to make it work using the java-sdk. Thanks though!
chill37 (Tue, 23 Apr 2019 11:41:22 GMT):
@rickr yes. when I used channel.queryByChaincode() instead of channel.sendProposalToEndorsers() using all peers, it worked successfully.
when I did some digging, I found out that, sdChaincodeMap outputs null when called from sendProposalToEndorsers()

rickr (Tue, 23 Apr 2019 12:10:43 GMT):
@chill37 What version of the SDK? Can you put the SDK in logging trace mode, reproduce the error and then paste the logs using https://ctrlv.it/
chill37 (Tue, 23 Apr 2019 12:11:54 GMT):
@rickr v1.4.0 hold on....let me give you the trace log
rickr (Tue, 23 Apr 2019 12:14:02 GMT):
if you can make sure it has included the point where the channel is being initialized to error.
chill37 (Tue, 23 Apr 2019 12:17:20 GMT):
@rickr https://ctrlv.it/id/174822/755764539 will this work?
chill37 (Tue, 23 Apr 2019 12:19:16 GMT):
@rickr https://ctrlv.it/id/174824/516370265 cleaner version
rickr (Tue, 23 Apr 2019 12:48:32 GMT):
@chill37 Can you try to see if what yacovm suggests to get another point of reference. Also include the peer log of that error
This maybe the SDK not sending the request ok, or environment setup doing the above will see if env. is ok.
chill37 (Tue, 23 Apr 2019 12:50:35 GMT):
@rickr
you mean just the discover command?
e.g.
1) discover --configFile conf.yaml --MSP Org1MSP --peerTLSCA /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/User1@org1.example.com/tls/ca.crt --userKey /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/keystore/bc777711397ae659a7d87ef5c9b6c6909b39757c0559b93637d1159f79bccf6e_sk --userCert /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/signcerts/User1@org1.example.com-cert.pem saveConfig
2) discover --configFile conf.yaml peers --channel mychannel --server peer0.org1.example.com:7051
chill37 (Tue, 23 Apr 2019 12:53:37 GMT):
OUTPUT: (got the whole peers)

rickr (Tue, 23 Apr 2019 12:54:56 GMT):
check if there is an option for chaincode query
chill37 (Tue, 23 Apr 2019 12:55:03 GMT):
or did you mean the one with endorser layout

is there an option for chaincode to chaincode ?
chill37 (Tue, 23 Apr 2019 12:56:34 GMT):
mycc2: https://ctrlv.it/id/174832/1659874682
chill37 (Tue, 23 Apr 2019 12:57:45 GMT):
well I made a chaincode function that invokes mycc2.query() or mycc2.invoke() function with response := stub.InvokeChaincode(anotherCCName, chainCodeArgs, anotherChannel)
chill37 (Tue, 23 Apr 2019 12:57:45 GMT):
well I made a chaincode function that invokes mycc2.query() or mycc2.invoke() function with response := stub.InvokeChaincode(anotherCCName, chainCodeArgs, anotherChannel) in my chaincode-exmaple.go
rickr (Tue, 23 Apr 2019 12:59:00 GMT):
on the command line there must be a chaincode mycc then mycc2
rickr (Tue, 23 Apr 2019 12:59:39 GMT):
Can you also rerun the sdk with trace and include the peer trace too
chill37 (Tue, 23 Apr 2019 13:03:11 GMT):
I did the trace log with -Dlogging.level.org.hyperledger.fabric.sdk=trace so peer is there too... or did you want protos.peer/?

@rickr I have followed the method for test execution and tried commands "mvn install" and "mvn package"..

rickr (Tue, 23 Apr 2019 13:44:16 GMT):
most likely not enough entropy http://giovannitorres.me/increasing-entropy-on-virtual-machines.html
rickr (Tue, 23 Apr 2019 13:48:25 GMT):
for now you could in org/hyperledger/fabric/sdk/identity/IdemixIdentitiesTest.java add ignore :
@Ignore

rickr (Tue, 23 Apr 2019 13:49:11 GMT):
if you're not doing Idemix stuff should be ok. otherwise you'll need to fix the entropy on the machine
sejalpawar (Tue, 23 Apr 2019 13:54:18 GMT):

Antimttr (Tue, 23 Apr 2019 14:40:45 GMT):
I know how to check for installation using queryInstalledChaincodes()
rickr (Tue, 23 Apr 2019 14:49:43 GMT):
Should be covered in the integration tests
Antimttr (Tue, 23 Apr 2019 14:50:47 GMT):

it is and it isnt
Antimttr (Tue, 23 Apr 2019 14:51:00 GMT):
see the integration tests actualy send out the transaction proposals
Antimttr (Tue, 23 Apr 2019 14:51:15 GMT):
and they test to verify that the proposal was accepted by the orderer(s)
Antimttr (Tue, 23 Apr 2019 14:51:22 GMT):
but what if you dont have the proposal?
Antimttr (Tue, 23 Apr 2019 14:51:25 GMT):
how to test then?

Antimttr (Tue, 23 Apr 2019 16:16:51 GMT):
@rickr correct me if i'm wrong but if you're using nodejs chaincode, then a call to private static boolean checkInstalledChaincode(HFClient client, Peer peer, String ccName, String ccPath, String ccVersion) shoudl contain a blank ccPath, since nodejs doesnt allow you to set a chaincode path when you're installing it originally, right?
Antimttr (Tue, 23 Apr 2019 16:16:51 GMT):

Antimttr (Tue, 23 Apr 2019 16:17:35 GMT):
atleast I'm getting a blank chaincode path when i retrieve the chaincode info object from the client
Antimttr (Tue, 23 Apr 2019 16:17:49 GMT):
i assume its because im using nodejs chaincode
Antimttr (Tue, 23 Apr 2019 16:18:42 GMT):
and even though i set this: `installProposalRequest.setChaincodeSourceLocation(Paths.get(chaincodePath).toFile());` it doesn't actually mean i'm setting a chaincodePath like you would with java chaincode
yacovm (Tue, 23 Apr 2019 16:47:50 GMT):
@rickr @chill37 https://gerrit.hyperledger.org/r/#/c/31068/
rickr (Tue, 23 Apr 2019 17:18:00 GMT):
@Antimttr Not clear what your asking. When installing chaincode only GO type chaincode needs a chaincode path.
rickr (Tue, 23 Apr 2019 17:19:18 GMT):
which is really the GOPATH. Node and Java have no concept of that.
Antimttr (Tue, 23 Apr 2019 18:52:09 GMT):
@rickr when I call 'chaincodeIDBuilder.setPath(chaincodePath);' during installation of chaincode on a nodejs chaincode type it throws an exception
Antimttr (Tue, 23 Apr 2019 18:52:09 GMT):
@rickr when I call `chaincodeIDBuilder.setPath(chaincodePath);` during installation of chaincode on a nodejs chaincode type it throws an exception
Antimttr (Tue, 23 Apr 2019 18:52:16 GMT):
says that i shouldnt set the path for node chaincode
Antimttr (Tue, 23 Apr 2019 18:52:27 GMT):
so i only set the path if its not node
Antimttr (Tue, 23 Apr 2019 18:53:45 GMT):
then later, when im reading my chaincodeinfo object, for the nodejs chaincode the getPath() returns an empty string
rickr (Tue, 23 Apr 2019 19:02:21 GMT):
ok
rickr (Tue, 23 Apr 2019 19:02:55 GMT):
that's what the Fabric returns if you don't set it.
chill37 (Wed, 24 Apr 2019 00:21:13 GMT):

Hi Team, is there a sample code for adding an organization dynamically to the channel using fabric-java-sdk
yyyyyyy9 (Wed, 24 Apr 2019 07:24:07 GMT):
Has left the channel.
JorgeNavarro (Wed, 24 Apr 2019 07:34:15 GMT):
Hello, someone has a basic example that explains how to create a channel with java sdk 1.3?
AndresMartinezMelgar.itcl (Wed, 24 Apr 2019 07:36:42 GMT):
Hi, if i have a 1.3 network version,can i use 1.0v from sdk?
yacovm (Wed, 24 Apr 2019 07:45:19 GMT):
@chill37 I merged the fix to all branches from 1.2 to the latest branch
rickr (Wed, 24 Apr 2019 11:08:49 GMT):
@anjalinaik I don't think so. If there is it would be a Fabric server config. I'd ask on #fabric-questions or #fabric-peer-endorser-committer
rickr (Wed, 24 Apr 2019 11:10:51 GMT):
@JorgeNavarro Nothing has changed on the SDK side. You need to create an orderer block using configtx tool It documented in the README.md
rickr (Wed, 24 Apr 2019 11:13:00 GMT):
@AndresMartinezMelgar.itcl Nothing that's ever tested. The expectation your app moves up with SDK version to match fabric. The SDK offers some _backward_ compatibility
AndresMartinezMelgar.itcl (Wed, 24 Apr 2019 11:40:30 GMT):
@rickr Thanks

AndresMartinezMelgar.itcl (Thu, 25 Apr 2019 06:23:51 GMT):
The variable "properties" of "Peer peer = client.new Peer (name, grpc URL, properties);" To which it refers? I know I have to create an object properties, but what do I have to put inside it?
bilalahmed (Thu, 25 Apr 2019 06:48:42 GMT):
Here is sample properties object:
Properties peerProperties = new Properties();
peerProperties.setProperty("sslProvider", "openSSL");
peerProperties.setProperty("negotiationType", "TLS");
peerProperties.setProperty("trustServerCertificate", "true"); //testing environment only NOT FOR PRODUCTION!
peerProperties.setProperty("hostnameOverride", "peer0.org1.example.com");
peerProperties.setProperty("pemFile", "/Users/BAY/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt");
bilalahmed (Thu, 25 Apr 2019 06:50:24 GMT):
please update accordingly
AndresMartinezMelgar.itcl (Thu, 25 Apr 2019 06:50:25 GMT):
@bilalahmed so properties doesnt come from any file?
bilalahmed (Thu, 25 Apr 2019 06:51:16 GMT):
it depends, you can specify properties/configs in some JSON/YAML file and read from that file to populate this properties object
bilalahmed (Thu, 25 Apr 2019 06:51:42 GMT):
please refer to the SDK Integration tests
AndresMartinezMelgar.itcl (Thu, 25 Apr 2019 06:52:08 GMT):

hello everybody, today i try to instantiate Java Chaincode in the fabric java sdk 1.4.0. i got success from peers admin but when i instantiate this chaincode to Channel i receive message "Java chaincode is work-in-progress and disabled" and receive status Failure, Could you explain me Why?

@darapich92 You must be going against a later Fabric version. I think java chaincode came in 1.3. If you are running that or later then ask on #fabric-java-chaincode

I have a network config of 5 Peers with 2 channels across a differing subset of the Peers. I am using Fabric 1.4.1, Java SDK, and have Service Discovery and the Eventing Services working within the client app. My question relates to periodically refreshing the Service Discovery info. Currently the service discovery happens within .initialize(). Is there a way of refreshing the channel information without tearing it down and calling initialize again? To do this I need to shutdown the channel, remove my BlockListeners and recreate everything again.

rickr (Mon, 29 Apr 2019 11:54:51 GMT):
@ZLL I don't know of a sample. The fabric should IMO document what needs to be done as it's not specific to the any SDK. UpdateChannelIT.java does show for the most simplistic change of a channel parameter (Batch size) changing. You'd roughly be doing that with I think the system channel.

@APelser Some configuration issue I'm thinking which is hard to determine from just a description. But If you are creating the channel via the SDK then *joining* the peers via the sdk .. if this is a connection configuration issue .. how is that working ?

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=h8bnHqQHc544KKyci) @rickr I don't think I am joining the peers, I am calling `Channel.addPeer()`/`Channel.addEventhub()`, and finally `Channel.initialize()` , as is done in the example I found online. As far as I understand, this is not the same as sending a join proposal - but please correct me if I'm wrong. Also, I actually managed to get things working by mapping _all_ ports to themselves in peers (7051->7051 in peer0, 7101->7101 in peer1, and so on) in the docker-compose file. I honestly have no idea why this would work better than what I did before (7051->7051 for peer0, 7101->7051 for peer1, ...). I'm not 100% sure this is a proper solution though, since mapping ports to themselves just feels silly - but maybe that's just due a lack of knowledge, of course. Any chance you could explain/know of a resource that will teach me how the ports used in the docker environment variables (CORE_PEER_ADDRESS, CORE_PEER_CHAINCODELISTENADDRESS, and so on) should relate to the port mappings? I thought I had this covered, since it was working without the Java SDK, but I clearly missed something.

This certificate is available when I use the solution/workaround I mentioned in my previous post, so I think this explains the error - the SSL handshake can't take place.

hello everybody, today i am trying to run Junit test with End2endIT.class but when i enroll user, i got error in `HFCAInfo info = ca.info();` and got this message `org.hyperledger.fabric_ca.sdk.exception.InfoException: Url:http://localhost:7054, Failed to get info` . could anybody tell me why? or localhost:7054 is offline?
ZLL (Tue, 30 Apr 2019 04:11:53 GMT):
@rickr Thanks, I found this file, but I am using Fabric 1.0.
Although I can't use it now, thank you for your answer.
tsnyder (Tue, 30 Apr 2019 07:14:26 GMT):
@rickr Thanks. Regarding the Service Discovery. When sending a transaction Proposal do you need to be using the channel.sendTransactionProposalToEndorsers(TransactionProposalRequest transactionProposalRequest, DiscoveryOptions discoveryOptions) method, or will any sendTransactionProposal method work to use updated Service Discovery info?
rickr (Tue, 30 Apr 2019 11:55:16 GMT):
@tsnyder I you're using SD you should be using that method for your endorsements.
sejalpawar (Tue, 30 Apr 2019 13:52:52 GMT):
@rickr Hey, is there support for Auditor in Idemix in Fabric Java sdk?
vhulendamoraba (Wed, 01 May 2019 01:05:55 GMT):
Has joined the channel.
darapich92 (Wed, 01 May 2019 14:14:44 GMT):
hi everybody, i wonder when i start fabric.sh up, i saw a command `Starting server in home directory: /etc/hyperledger/fabric-ca-server` but i could not find that file in that directory. do you know where is it?
rickr (Wed, 01 May 2019 16:27:01 GMT):
Probably in the docker container running the fabric-ca
Antimttr (Wed, 01 May 2019 17:16:23 GMT):
Is there any reason why or how a registrar could successfully enroll a user, but then the same registrar user fails this call: `identities = ca.getHFCAIdentities(orgAdmin);` ?
Antimttr (Wed, 01 May 2019 17:16:45 GMT):
Got this result: `[HTTP Status Code: 401] - Error while getting all users from url 'https://localhost:8054': GET request to https://localhost:8054 failed request body . Response: {"result":"","errors":[{"code":20,"message":"Authentication failure"}`
Antimttr (Wed, 01 May 2019 17:17:06 GMT):
yet the same registrar user is able to register new users just fine
Antimttr (Wed, 01 May 2019 17:17:30 GMT):
confirmed name and secret are the same as defined in network-config.yaml
rickr (Wed, 01 May 2019 17:19:22 GMT):
@skarim ^^^
skarim (Wed, 01 May 2019 17:24:37 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=WxnMjFfaG9hFA6FKp) @Antimttr The read the docs on listing identities describes the authorization checks that are performed. Please refer to: https://hyperledger-fabric-ca.readthedocs.io/en/release-1.4/users-guide.html#dynamically-updating-identities
The two things you should check to see if you can get a particular user are type and affiliation.
Antimttr (Wed, 01 May 2019 17:35:05 GMT):
@skarim according to the javadoc for getHFCAIdentities() should ` gets all identities that the registrar is allowed to see` so in my case i tried to use the registered org admin so it should see all the registered users in the org
Antimttr (Wed, 01 May 2019 17:36:46 GMT):
atleast thats what it does when i use the same operation with the node sdk
Antimttr (Wed, 01 May 2019 19:31:10 GMT):
why would a registrar which works fine to register and enroll new identities not be allowed to list them
Antimttr (Wed, 01 May 2019 19:31:12 GMT):
it makes no sense
Antimttr (Wed, 01 May 2019 21:19:41 GMT):
@skarim so i can get the identity lists with the client this way: `/fabric-ca-client identity list -u https://admin:adminpw@ca.org2.example.com:8054 --tls.certfiles /home/mwest/go/src/github.com/hyperledger/fabric-samples/balance-transfer/artifacts/channel/crypto-config/peerOrganizations/org2.example.com/ca/ca.org2.example.com-cert.pem

Antimttr (Wed, 01 May 2019 21:19:41 GMT):
@skarim so i can get the identity lists with the client this way: ```/fabric-ca-client identity list -u https://admin:adminpw@ca.org2.example.com:8054 --tls.certfiles /home/mwest/go/src/github.com/hyperledger/fabric-samples/balance-transfer/artifacts/channel/crypto-config/peerOrganizations/org2.example.com/ca/ca.org2.example.com-cert.pem

Antimttr (Wed, 01 May 2019 21:20:20 GMT):
however doing the same command through the sdk fails
Antimttr (Wed, 01 May 2019 21:20:33 GMT):
as i detailed above
Antimttr (Wed, 01 May 2019 21:23:07 GMT):
as far as i can tell the admin user is a valid registrar
Antimttr (Wed, 01 May 2019 21:23:17 GMT):
if im interperating that correctly
Antimttr (Wed, 01 May 2019 21:28:01 GMT):
@rickr is there any way through the sdk to specify a cert file for the user like i did with the command line client?
Antimttr (Wed, 01 May 2019 21:28:30 GMT):
all the user object has is its own Enrollment object which i dunno if thats the same data as the tls cert file but perhaps that's what it needs?
Antimttr (Wed, 01 May 2019 21:30:21 GMT):
``` Enrollment enroll = caClient.enroll(orgAdmin.getName(), config.GetAdminSecret(orgNum));
orgAdmin.setEnrollment(enroll);
orgAdmin.setEnrollmentSecret(config.GetAdminSecret(orgNum));
orgAdmin.setMspId(org.getMSPID());
orgAdmin.setTlsCertPEM(enroll.getCert());
orgAdmin.setTlsKeyPEM(Crypto.getPEMStringFromPrivateKey(enroll.getKey()));
orgAdmin.setEnrolled(true);
orgAdmin.setType("CA_ADMIN");
org.setAdmin(orgAdmin);
System.out.println("Admin username: " + orgAdmin.getName() + " pass: " + orgAdmin.getEnrollmentSecret());
System.out.println("Printing Enrollment Data for Registrar: ");
LedgerUserModel.outputEnrollmentAuth(orgAdmin, CryptoSuite.Factory.getCryptoSuite());
Collection identities = null;
try {
identities = caClient.getHFCAIdentities(orgAdmin);
} catch(IdentityException ie) {
System.out.println("ERROR: ListAllUsers: Identity Exception received: "
+ ie.getMessage());
} catch(InvalidArgumentException ie) {
System.out.println("ERROR: ListAllUsers: Invalid registrar user passed: "
+ ie.getMessage());
}```
Antimttr (Wed, 01 May 2019 21:30:27 GMT):
here is the code from my client
Antimttr (Wed, 01 May 2019 21:30:51 GMT):
as you can see its literally enrolling the admin, then immediately using that enrollment object to query for identities
Antimttr (Wed, 01 May 2019 21:30:53 GMT):
and its failing
Antimttr (Wed, 01 May 2019 21:31:21 GMT):
however I can use the same user to register new identities with the same CA
Antimttr (Wed, 01 May 2019 21:37:24 GMT):
this is the result of that code: ```

Antimttr (Wed, 01 May 2019 21:37:58 GMT):
as you can see the username and password are correct, and the enrollmen data exists
Antimttr (Wed, 01 May 2019 21:38:40 GMT):
does the sdk need to be configured to use tls? i mean all the other operations i send to it work fine
Antimttr (Wed, 01 May 2019 21:38:43 GMT):
its just this one operation
rickr (Wed, 01 May 2019 22:06:01 GMT):
Nothing with TLS because you got a 401. I think if you go log at the fabric_ca logs you'll see it's processing it. So please take those logs to the #fabric-ca channel and and first find out why it's not working. If they indicate the sdk is somehow sending the wrong request then we can look at here.

by fabric_ca logs you mean the logs generated on the fabric_ca docker, correct?
rickr (Wed, 01 May 2019 22:07:46 GMT):
That would be them
Antimttr (Wed, 01 May 2019 22:07:58 GMT):
ok ill figure out how to get to them
rickr (Wed, 01 May 2019 22:09:52 GMT):
BTW make sure you're also using the latest SDK
Antimttr (Wed, 01 May 2019 22:10:21 GMT):
i think i dled it when it was 1.4.0
Antimttr (Wed, 01 May 2019 22:10:25 GMT):
i havent updated since then
Antimttr (Wed, 01 May 2019 22:10:41 GMT):

Antimttr (Wed, 01 May 2019 22:18:06 GMT):

Antimttr (Thu, 02 May 2019 16:54:12 GMT):
seems like the nodejs sdk also gets that message

but simply carries on and continues to get the requested data
Antimttr (Thu, 02 May 2019 16:54:35 GMT):
where as the javasdk just stops after that 3rd line
rickr (Thu, 02 May 2019 17:54:30 GMT):
put the jsdk in trace mode logging and the CA output full!! and paste to https://ctrlv.it/ @skarim
rickr (Thu, 02 May 2019 17:54:30 GMT):
put the jsdk in trace mode logging and the CA output full!! and paste both using https://ctrlv.it/ @skarim
Antimttr (Thu, 02 May 2019 17:56:58 GMT):
ok
rickr (Thu, 02 May 2019 17:57:57 GMT):
and you're on JSDK >= v1.4 ?
rickr (Thu, 02 May 2019 17:59:02 GMT):
if thats the case you should never see that 3rd line because only the new authentication is actually used.
Antimttr (Thu, 02 May 2019 17:59:07 GMT):
java sdk 1.4.1
Antimttr (Thu, 02 May 2019 17:59:17 GMT):
i also updated the dockerr images to 1.4.1
rickr (Thu, 02 May 2019 17:59:45 GMT):
Have looked at the JSDK examples of using that api?
Antimttr (Thu, 02 May 2019 18:00:01 GMT):
yes, thats where i got the code from,
rickr (Thu, 02 May 2019 18:00:37 GMT):
probably the problem (just kidding )
Antimttr (Thu, 02 May 2019 18:01:01 GMT):
specifically: hfcaclientit.java line 648
Antimttr (Thu, 02 May 2019 18:01:23 GMT):
its pretty straight forward
rickr (Thu, 02 May 2019 18:01:30 GMT):
Are you using the docker fabric that the SDK comes whith ... or your own ?
Antimttr (Thu, 02 May 2019 18:01:35 GMT):
just grabs the ca admin, and then uses it to call the function
Antimttr (Thu, 02 May 2019 18:02:08 GMT):
im using the docker image i just grabbed this morning from the main hyperledger repo
Antimttr (Thu, 02 May 2019 18:02:34 GMT):
and the sdk i got via maven: ```
org.hyperledger.fabric-sdk-java
fabric-sdk-java
1.4.1
```
rickr (Thu, 02 May 2019 18:02:35 GMT):
but are you using the fabric set up in the SDK our your own ?
Antimttr (Thu, 02 May 2019 18:02:49 GMT):
oh im using balance-transfer
Antimttr (Thu, 02 May 2019 18:02:53 GMT):
from samples
Antimttr (Thu, 02 May 2019 18:04:35 GMT):
and didnt really change it much besides using a slightly modified chaincode
Antimttr (Thu, 02 May 2019 19:41:52 GMT):
@rickr Do i need to export ORG_HYPERLEDGER_FABRIC_SDK_DIAGNOSTICFILEDIR in order for the sdk to output, or is it outputting to stderr? I dont see any extra output on stdout
Antimttr (Thu, 02 May 2019 19:42:11 GMT):
or does it use some sort of logging system
Antimttr (Thu, 02 May 2019 19:45:33 GMT):
ahh ok i think you set it in properties that you feed to the client object
Antimttr (Thu, 02 May 2019 19:45:35 GMT):
ill try that
rickr (Thu, 02 May 2019 19:57:04 GMT):
You don't need ORG_HYPERLEDGER_FABRIC_SDK_DIAGNOSTICFILEDIR only for fabric not fabric-ca interaction
Antimttr (Thu, 02 May 2019 20:02:27 GMT):
ok set the export ORG_HYPERLEDGER_FABRIC_CA_SDK_LOGLEVEL=TRACE in the shell running my client and in the properties for HFCAClient i set LOGGERLEVEL to TRACE
Antimttr (Thu, 02 May 2019 20:02:27 GMT):
ok set the export ORG_HYPERLEDGER_FABRIC_CA_SDK_LOGLEVEL=TRACE in the shell running my client and in the properties for HFCAClient i set 'org.hyperledger.fabric.sdk.loglevel' to TRACE
Antimttr (Thu, 02 May 2019 20:02:29 GMT):
hoping that does
Antimttr (Thu, 02 May 2019 20:10:47 GMT):
also set in my docker-compose.yaml for both the ca's: FABRIC_LOGGING_SPEC=DEBUG
Antimttr (Thu, 02 May 2019 20:11:17 GMT):
though i think balance-transfer does that already
Antimttr (Thu, 02 May 2019 20:13:50 GMT):
ok here's my ca output: https://ctrlv.it/id/176614/70646644
Antimttr (Thu, 02 May 2019 20:14:52 GMT):
i didnt notice any extra output to my java client with those options enabled but heres the output anyways: https://ctrlv.it/id/176615/3301194123
rickr (Thu, 02 May 2019 20:22:01 GMT):
where is the corresponding SDK trace ?
Antimttr (Thu, 02 May 2019 20:22:12 GMT):
where does the sdk trace show up on?
Antimttr (Thu, 02 May 2019 20:22:23 GMT):
doesnt seem to go to sdtout
rickr (Thu, 02 May 2019 20:22:27 GMT):
by default to the console
Antimttr (Thu, 02 May 2019 20:22:39 GMT):

@Antimttr would it be easy for you to change your ca name to remove the dash and see if that then works?
Antimttr (Thu, 02 May 2019 20:50:59 GMT):
i think so, its just in the artifacts config files
Antimttr (Thu, 02 May 2019 20:51:00 GMT):
let me try
Antimttr (Thu, 02 May 2019 20:58:30 GMT):

@Antimttr I think we have it reproduced. But it may be next week before get any fix out
Antimttr (Thu, 02 May 2019 21:34:19 GMT):
oh wow, its an actual bug?
Antimttr (Thu, 02 May 2019 21:34:34 GMT):
ok, i'll wait patiently, thanks for your help :D
rickr (Thu, 02 May 2019 22:43:53 GMT):
@Antimttr I'm guessing your fabric-ca is not really using multiple instance (multiple ca names configured) you could try create the hfclient w/o any caname. It defaults to the root one if there is only one and that I think will get around the issue.

hello all
I am interested on collobarate in hyperladger fabric java sdk
How i can involved? where i can get tasks to make and request pull ?
rickr (Fri, 03 May 2019 11:37:52 GMT):
@yerganat some thing to get started is doc'ed in fabric docs
https://fabric-docs-test.readthedocs.io/en/latest/CONTRIBUTING/
Is probably the place to start. Take note of the gerrit part as github is not used.
Antimttr (Fri, 03 May 2019 14:41:11 GMT):

Hi everyone, I am trying to deploy and initiate Java chaincode from Java SDK. But getting failure response. Can you please walkthrough how to deploy and initiate Java chaincode from Java client SDK?
rickr (Mon, 06 May 2019 11:53:50 GMT):
@darapich92 Starting with the SDK at _ground zero_ is not IMO the best bet. Look through the Fabric documentation to get some background first. Endorsement is done by the Peer that's in the SDK setup is running in docker. It's not http but grpc protocol that's used to communicate between SDKs and the Fabric.

Hey there, I am trying to invoke transaction using an idemix credential:
rickr (Mon, 06 May 2019 11:57:24 GMT):
@VivekAnandPanda If you follow the SDK README.md it guides you to get the Integration test running and passing. One of the integration test does deploy Java chaincode. The Readme.md does reference it. Please take the time to follow that
sejalpawar (Mon, 06 May 2019 11:57:58 GMT):
UserContext idemixUser = new UserContext();
idemixUser.setName("idemixTestUser18");
RegistrationRequest rr = new RegistrationRequest(idemixUser.getName(), "org1");
String enrollmentSecret = ca_client.register(rr, caAdmin);
String mspID = "Org1IdemixMSP";
Enrollment x509Enrollment = ca_client.enroll(idemixUser.getName(), enrollmentSecret);
Enrollment idemixEnrollment = ca_client.idemixEnroll(x509Enrollment, mspID);
System.out.println(idemixEnrollment.getCert()); //returns null
System.out.println(idemixEnrollment.getKey()); //returns null
idemixUser.setEnrollment(idemixEnrollment);
idemixUser.setMspId(mspID);
client.setUserContext(idemixUser);
sejalpawar (Mon, 06 May 2019 11:58:38 GMT):
On the SDK side, I get: Expecting a PEM-encoded X509 certificate; PEM block not found
org.hyperledger.fabric.sdk.exception.InvalidArgumentException: Proposal response is invalid.
sejalpawar (Mon, 06 May 2019 11:59:20 GMT):

Is the usercontext you're using set to a user with an Idemix mspid ?
rickr (Mon, 06 May 2019 12:02:16 GMT):
Please follow the code provided as an example in the Integration tests.
sejalpawar (Mon, 06 May 2019 12:07:49 GMT):
I have two MSPs: Org1MSP is an x509 MSP and Org1IdemixMSP is the idemix MSP
sejalpawar (Mon, 06 May 2019 12:08:05 GMT):
In the code above, I had set it to Idemix MSP
sejalpawar (Mon, 06 May 2019 12:08:18 GMT):
Is that incorrect?
rickr (Mon, 06 May 2019 12:09:53 GMT):
looks right
sejalpawar (Mon, 06 May 2019 12:17:15 GMT):
It ran once correctly and started failing thereafter. Is there some kind of default setting that I need to override on the CA side? I simply init and start the CA server fabric-ca-server start -b admin:adminpw --home $PWD
rickr (Mon, 06 May 2019 12:24:20 GMT):
You need to restart if you want to again register the same user .. ask on #fabric-ca
darapich92 (Mon, 06 May 2019 13:12:41 GMT):
@rickr thank you for your recommendation. Please correct me if i am wrong. I understand Endorsers who role to endorse the client's tx. Since i test that End2endIT java sdk, i don't know what kind of policy that endorsers check before endorse client's tx. Could you tell me how can i access to endorser's code?
sejalpawar (Mon, 06 May 2019 13:40:26 GMT):
okay I will look into it.. thanks

ranjan008 (Tue, 07 May 2019 04:55:34 GMT):
@rickr can I implement custom store to store keys and certificates through java-sdk ? If yes which interface should I override in java?
rickr (Tue, 07 May 2019 12:05:26 GMT):
No need for that
rickr (Tue, 07 May 2019 12:05:26 GMT):
No need for that. As an application store them in your own database in what ever fomat works best for your application
rickr (Tue, 07 May 2019 12:05:26 GMT):
No need for that. As an application store them in your own database in what ever format works best for your application. The SDK is IMO for interacting with Fabric. There are dozen of persistent technologies in Java that all the SDK would do is call your application back to do the actual store in whatever schema your application desired.

Hey there! I am invoking a transaction using an idemix user twice and returning the creator's public key from chaincode side which is used to raise the transaction. However, the byte[] array returned is different in the two transaction requests. Is there an issue with my implementation or is this intended?
sejalpawar (Wed, 08 May 2019 08:10:24 GMT):
This is my code to access public key of creator on chaincode side:
sejalpawar (Wed, 08 May 2019 08:10:54 GMT):
creator, err := stub.GetCreator()
if err != nil {
return shim.Error(err.Error())
}
sid := &msp.SerializedIdentity{}
err = proto.Unmarshal(creator, sid)
if err != nil {
return shim.Error("failed to unmarshal transaction invoker's identity "+err.Error())
}
idemixID := &msp.SerializedIdemixIdentity{}
err = proto.Unmarshal(sid.IdBytes, idemixID)
if err != nil {
return shim.Error("failed to unmarshal transaction invoker's idemix identity "+err.Error())
}
return shim.Success(idemixID.Nymx)

In Java SDK: byte[] res = responses.iterator().next().getChaincodeActionResponsePayload();
for(byte x: res) System.out.print(x+" ");
rickr (Wed, 08 May 2019 13:08:24 GMT):
Ok - not being the idemix guru I do think that's the intent. It should generate a new creator cert each time making it _non-linkable_

Is there anyone that could guide me on how to update a client side application using the java fabric SDK connect to an IBP enterprise service when Mutual TLS is enabled?
casstait (Thu, 09 May 2019 06:11:10 GMT):
When mutual TLS is disabled on the IBP service, the code currently written works as expected, however when mutual TLS is enabled on the IBP service, I receive an error: Response: {"result":"","errors":[{"code":0,"message":"Registration of 'casstest' failed in affiliation validation: : scode: 401, local code: 44, local msg: Caller does not have authority to act on affiliation 'PeerOrg1', remote code: 20, remote msg: Authorization failure"} ],"messages":[],"success":false}. What do I need to do to alter the existing code to establish a mutual TLS connection? I used the following tutorial as a guide: https://developer.ibm.com/tutorials/hyperledger-fabric-java-sdk-for-tls-enabled-fabric-network/
tsnyder (Thu, 09 May 2019 10:57:05 GMT):
I have working code with the java sdk with uses Service Discovery to obtain the channel information and accesses both the Peers and Orderers using TLS. The Connections to the Peers and Service Discovery works fine. Endorsement works fine. If I have a solo Orderer sending to the Orderer works fine. However, if I use etcdraft Orderers I receive a certificate validation error as follows: 1759 [grpc-default-worker-ELG-1-2] DEBUG io.netty.handler.ssl.ReferenceCountedOpenSslContext - verification of certificate failed
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
tsnyder (Thu, 09 May 2019 11:00:09 GMT):
The gossip is working, the channel creation is working, Peer connection to the Orderers is working. It is only the Client APP to the etcdraft Orderer nodes where the SSL handshake does not work. Within the Orderer I see the following series of messages - 2019-05-09 06:45:56.898 UTC [core.comm] ServerHandshake -> ERRO 0b1 TLS handshake failed with error remote error: tls: internal error server=Orderer remoteaddress=172.17.0.14:56220

Alll Fabric components including the Java SDK are 1.4.1
rickr (Thu, 09 May 2019 12:38:31 GMT):
@casstait does not appear as TLS error as it seems like it made the connection. Support for IBM IBP is through IBM you should open a support ticket.
rickr (Thu, 09 May 2019 12:48:46 GMT):
@tsnyder no way to guess from just that description. The SDK gets certs from SD so there's no way to know what it received was at fault or what it did with what it received is at fault :smile: The SDK is _clueless_ about whether Orderer is solo, kafka, or raft based. Would need complete logs at trace level for all involved SDK, orderer, and peers from the very begging to point of failure to even begin to isolate.
tsnyder (Thu, 09 May 2019 12:50:50 GMT):
@rickr I have the logs from the BasicConfiguration.configure() within the sdk. Only partial logs from the Orderer nodes. It is inside a Kubernetes environment.
tsnyder (Thu, 09 May 2019 12:51:12 GMT):
how can I send them to you? They are very long (pages)
rickr (Thu, 09 May 2019 12:52:09 GMT):
You could also override the SD add orderer and get the certificate or get the certificates from the logs and try and use openssl s_client to see if they work with it
rickr (Thu, 09 May 2019 12:52:33 GMT):
that would be insightful

HLF 1.4.0, Java SDK 1.4.0, Go Chaincode: When using ServiceDiscovery in call to channel.sendTransactionProposalToEndorsers and chaincode exits with shim.Error("message"), I cannot get access to "message", as that method call throws org.hyperledger.fabric.sdk.exception.ProposalException: org.hyperledger.fabric.sdk.exception.ServiceDiscoveryException: Could not meet endorsement policy for chaincode. If do not use ServiceDiscovery, then I receive ProposalResponses with isVerified=false containing the "message" and other error info (status, etc.) that I can then read. Am I doing something wrong? How can I get the detailed error info when using ServiceDiscovery?
rickr (Thu, 09 May 2019 20:12:42 GMT):
@dan13 What was the actual error ? Maybe need an *improvement* on that error path.
dan13 (Thu, 09 May 2019 20:20:17 GMT):
@rickr Go chaincode: return shim.Error("No data found for " + id)
where the preceding operation was a query call to another chaincode on a different channel (this call worked, just returned no results which is an application error for our use case)
rickr (Thu, 09 May 2019 20:21:31 GMT):
So I should reproduce by have SD executed some chaincode that returns an error
dan13 (Thu, 09 May 2019 20:22:39 GMT):
yes, it should be that simple. For reference, the full method call for us is:
proposalResponses = channel.sendTransactionProposalToEndorsers(proposalRequest,
createDiscoveryOptions().setEndorsementSelector(ServiceDiscovery.EndorsementSelector.ENDORSEMENT_SELECTION_RANDOM)
.setForceDiscovery(true));
dan13 (Thu, 09 May 2019 20:22:39 GMT):
yes, it should be that simple. For reference, the full method call for us is:
proposalResponses = channel.sendTransactionProposalToEndorsers(proposalRequest,
createDiscoveryOptions().setEndorsementSelector(ServiceDiscovery.EndorsementSelector.ENDORSEMENT_SELECTION_RANDOM)
.setForceDiscovery(true));
as opposed to (non-SD):
proposalResponses = channel.sendTransactionProposal(proposalRequest, channel.getPeers(EnumSet.of(Peer.PeerRole.ENDORSING_PEER)));
rickr (Thu, 09 May 2019 20:25:08 GMT):
The actual fix is probably in the SD handler which is only a _reference implementation_ and can be replaced by the application :) :)

.. was mostly _tongue in cheek_ .. still will look in to fixing it

the error seems to originate in Channel class, if I'm reading things correctly

@rickr My RTFM error: inspectResults: If service discovery does not find the the needed endorsers for a specific chaincode it will by default throw a ServiceDiscoveryException. Setting this to true will have the method return the all the endorsements it did obtained. Setting this true fixed my issue.

It's well written, easy to follow, but, I am confused about from where does they are loading properties file. I couldn't find any properties file with the name HFCSampletest.properties anywhere. Could someone point me to the required properties file to run a fabric-sdk-java.

@rickr Could you please share a sample properties file.

Hello everyone, I'm working with the java sdk at the moment and reading my connection details from a json/yaml file. However I can't seem to find how to get the peer and orderer url from the NetworkConfig class? Can anyone help me out?

I took a look at the code and file seems to be created when running the setup
nitishbhardwaj19 (Sat, 11 May 2019 13:11:55 GMT):
ohh that's great. I can't run it in my local due to some technical restrictions. Will it be possible for you to share the generated file? I am curious to know how we can use the connection.json to configure required properties in this SDK.
Jelle.Diet (Sat, 11 May 2019 13:14:38 GMT):
I think I have the connection yaml file for the basic network somewhere hold on
rickr (Sat, 11 May 2019 14:07:12 GMT):
@Jelle.Diet Not following exactly what it is you're doing. Should not be necessary. Follow the NetworkconfigIT example it loads the channel from the connection property file. Once loaded you _could_ query the channel for peers and orderers that have the URL but not sure why that is even needed.
https://github.com/hyperledger/fabric-sdk-java/blob/433432f4fb7f04251f40af0b2e1af96678169804/src/test/java/org/hyperledger/fabric/sdkintegration/NetworkConfigIT.java

rickr (Sat, 11 May 2019 14:16:37 GMT):
@nitishbhardwaj19 HFCSampletest.properties you won't find it. It's created as the test is run. Should be deleted after testing is done.
Jelle.Diet (Sat, 11 May 2019 14:39:43 GMT):
Ah I made it work, I was creating a new channel and adding a peer and orderer to it manually
tsnyder (Sun, 12 May 2019 07:23:32 GMT):
@rickr - I have isolated the problem with the Service Discovery, TLS and Raft. The issue is that when each node (Peer or Orderer) is built within the EndPoint it first does not find the SSL Context. It then goes and finds the TLS Cert. For the orderer nodes it always uses the orderer1 cert and not the orderer orgs tls cert. I ran the test using the BasicConfigure and SSL tracing. I have raised a jira item on this. I attached the console log, configtx.yaml, and crypto-config.yaml to the jira item.
nitishbhardwaj19 (Sun, 12 May 2019 14:27:12 GMT):
Thanks @rickr for your quick response.
nitishbhardwaj19 (Sun, 12 May 2019 15:42:06 GMT):
Hi @rickr What is the optimal way for creating an instance of HFCAClient and HFClient. Should it be created just once for each org or a new instance must be created for each operation?

AndresMartinezMelgar.itcl (Mon, 13 May 2019 06:29:56 GMT):
Hi, I'm using the java sdk. When I make a valid transaction a new block is created (normal behavior) but when I make a query I also create a block.
I understand that this behavior is not normal, but I do not know for sure.
I think i am not using correct function
oborovyk (Mon, 13 May 2019 11:36:47 GMT):
Hi @rickr . Are the readme params(https://github.com/hyperledger/fabric-sdk-java#firewalls-load-balancers-network-proxies) enough for grpc problem solving?
oborovyk (Mon, 13 May 2019 11:39:44 GMT):
we are using loadChannelFromConfig(...) but it can't read the keepAliveWithoutCalls boolean property. there's a workaround for keepAliveTimeout, keepAliveTime in NetworkConfig though
rickr (Mon, 13 May 2019 11:52:33 GMT):
@oborovyk NetworkConfigIT shows how you can add any propertes or change them before any channel is loaded.
rickr (Mon, 13 May 2019 11:55:58 GMT):
@AndresMartinezMelgar.itcl block should not be written if your chaincode doing the query is not changing any properties. Also if it's just a query using your chaincode it should not be sent to the Orderer by your application.
oborovyk (Mon, 13 May 2019 12:39:59 GMT):
cool that worked. Can we add a pull request to fix the loadChannelFromConfig method?
rickr (Mon, 13 May 2019 12:53:39 GMT):
nothing is broken
oborovyk (Mon, 13 May 2019 12:59:10 GMT):
I think it should work with json only without adding properties manually. Or was it intended for partial load? Look at: private Node createNode.. in NetworkConfig.java. Wdyt?
rickr (Mon, 13 May 2019 13:01:15 GMT):
The document was for network providers to tell how to configure your network for what they provided. Those properties are specific to your client. Your application may behind a firewall and need them some other application may not.
Igor-Ivaniuk (Mon, 13 May 2019 13:05:59 GMT):
The point was that the defined properties are not parsed according to JSON types, but rather are provided as Strings
Igor-Ivaniuk (Mon, 13 May 2019 13:07:09 GMT):
Which is not compatible with, for example, Netty GRPC implementation
oborovyk (Mon, 13 May 2019 13:09:41 GMT):
Indeed and there's a workaround in NetworkConfig but only for 2 props if (null != props) {
String value = props.getProperty("grpc.keepalive_time_ms");

It actually fails at hfcaClient.info() when it tries to call CA http://xx.xxx.xxx.xxx:7054/api/v1/cainfo, gets Connection Timeout. But, I can't find any logs on CA. Seems like it's not able to reachout to CA. Strange thing is that the same configuration worked with Node SDK. It would be really great if someone can help me out with this.

@AndresMartinezMelgar.itcl look at https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/java/org/hyperledger/fabric_ca/sdkintegration/HFCAClientIT.java
search for HFCAIdentity see if those APIs help
rickr (Wed, 15 May 2019 12:00:52 GMT):
@nitishbhardwaj19 The SDK tests run with TLS enabled connecting the HFCAClient and are passing. Have you followed it? As an independent connect try using `openssl s_client -connect` to see if that works
rickr (Wed, 15 May 2019 12:02:58 GMT):
Also I see a url in that one picture that looks to be url="http:/..." if this is tls I think *https* is going to work better.
nitishbhardwaj19 (Wed, 15 May 2019 12:58:03 GMT):
@rickr Thanks for replying. I have not configured TLS anywhere in HLF network. This is just a test network to check the connectivity with SDK. I am able to connect with Postman though. I am not sure why it doesn't connect with SDK client, trying to enable fiddler logs to get more information. I will update you soon.

nitishbhardwaj19 (Wed, 15 May 2019 13:16:54 GMT):
Fabric version is 1.4. I found the issue. It's because of the proxy which is being configured. The Proxy isn't allowing any http communication and I get connection timeout. Fiddler actually helped me to identify it. @rickr Thanks alot for looking into this. Though I am getting another error now, but at least the first one is resolved. :)

When you getHistory for a key you get all the transactions, timestamps and an isDelete flag

Jelle.Diet (Fri, 17 May 2019 11:49:12 GMT):
Ah yes from the blockinfo it gets the mspId and certificate of the user, can it also be used to get the name? and can the same be done from TransactionInfo instead of BlockInfo?
rickr (Fri, 17 May 2019 12:05:18 GMT):
There is no `name`, Only mspid and the signers signature Whats there is what I know is available
Jelle.Diet (Fri, 17 May 2019 12:06:08 GMT):
how would you recommend getting the signing User from that information?
dan13 (Fri, 17 May 2019 14:21:11 GMT):
@Jelle.Diet the cert contains the username, right?
SandySun2000 (Fri, 17 May 2019 16:37:15 GMT):
@rickr The tutorial "https://developer.ibm.com/tutorials/hyperledger-fabric-java-sdk-for-tls-enabled-fabric-network" helps to connect to an IBP instance where the TLS was enabled, that could help to establish mTLS, but the tutorial didn't show the steps how the IBP instance will authenticate to the app using its certificate. Do you have any doc or tutorial to explain the missing steps?
rickr (Fri, 17 May 2019 17:17:01 GMT):
Mutual TLS if that's what your asking about is done by the grpcs /ssl connection layer. The only requirement is the client/sdk/application needs to provide for the connecit is a client certificate.

Likely that you're using a new version of java where the modules were removed.

Hi guys. Is it possible (and is there any examples) for interacting with byfn network (without ca) using Java SDK?
DVasin (Mon, 20 May 2019 13:04:59 GMT):
Is is ca nessecary for accessing the network via Java SDK?
rickr (Mon, 20 May 2019 21:25:43 GMT):
No CA is strictly required for Fabric. I just connected to Fabric's BYFN load I'ts user/creds and tls/certs for the connections.

hi to all,
I'm using the java sdk to connect to my network and i received a peculiar error:

Instead of using fabric directly using SDK, can we use hyperledger composer directly for all cases ?

Randyshu2018 (Tue, 21 May 2019 07:00:35 GMT):
only org admin can submit transaction ?
nitishbhardwaj19 (Tue, 21 May 2019 07:03:41 GMT):
@Randyshu2018 Any user can submit the transaction as long as he is a part of the organization. For that, you would have to first register and enroll different users for the organization(using org admin).
Randyshu2018 (Tue, 21 May 2019 07:04:44 GMT):

nitishbhardwaj19 (Tue, 21 May 2019 07:06:46 GMT):
How are you managing your Enrollment certs? Do you use the same set of certs to create User object which is being generated at the time of enroll?
Randyshu2018 (Tue, 21 May 2019 07:08:04 GMT):
Using fabric-ca interface to register and enroll user and then save the enroment to the samplestore
Randyshu2018 (Tue, 21 May 2019 07:08:54 GMT):
when using user,I get user from samplestore and then setUserContext.
Randyshu2018 (Tue, 21 May 2019 07:10:54 GMT):
I think the user cert is invalid except admin .but I need some method to correct them,do you have any idea
Randyshu2018 (Tue, 21 May 2019 08:38:43 GMT):

This feature never returns and time-outs (despite transaction being commited to ledger)
DVasin (Tue, 21 May 2019 11:36:26 GMT):
I configure channels like this (i,e. adding event hub)
Peer peer = client.newPeer("peer0.org1.example.com", "grpc://localhost:7051");
// eventhub name and endpoint in fabcar network
EventHub eventHub = client.newEventHub("eventhub01", "grpc://localhost:7053");
// orderer name and endpoint in fabcar network
Orderer orderer = client.newOrderer("orderer.example.com", "grpc://localhost:7050");
// channel name in fabcar network
Channel channel = client.newChannel("mychannel");
channel.addPeer(peer);
channel.addEventHub(eventHub);
channel.addOrderer(orderer);
channel.initialize();
return channel;
DVasin (Tue, 21 May 2019 11:36:26 GMT):
What am I doing wrong, any ideas?
rickr (Tue, 21 May 2019 11:53:30 GMT):
@smallant Not sure how that is happening. That's the first case of that error code I've seen reported here. I can only _ guess _ you're sending the endorsement to the Orderer twice? May take that to the #fabric-peer-endorser-committer channel.
rickr (Tue, 21 May 2019 11:57:17 GMT):
@sandy There is no *composer* for Java. Work is in progress for Java programming model. It only I think covers transactions ( invoking chiancode ) https://github.com/hyperledger/fabric-gateway-java
rickr (Tue, 21 May 2019 12:01:32 GMT):
@nitishbhardwaj19 Yes the application needs to manage persisting it's data. The SampleStore and SampleOrg have a simple implementation of it.
rickr (Tue, 21 May 2019 12:04:47 GMT):
@darapich92 Depends on serveral factors like in the configblock there is a batch size that will trigger a block to be created once that's reached and a some timeout. For exact details ask on #fabric-orderer
rickr (Tue, 21 May 2019 12:08:02 GMT):
@DVasin not directly releated to your question but eventhubs have long been deprecated. What version of fabric/sdk are you using? Up the time 5min ? see what happens.
rickr (Tue, 21 May 2019 12:08:02 GMT):
@DVasin not directly releated to your question but eventhubs have long been deprecated. What version of fabric/sdk are you using? Up the time 5min ? see what happens. Also putting the sdk to logging trace mode shows if events are being received and after about 10 min there is a cleanup thread that kicks off and should report with a warning for any transactions that have not received a response.

Using the resources here: https://github.com/hyperledger/fabric-sdk-java/tree/master/src/test/fixture/sdkintegration
This is a good example of what the SDK can do. There are a lot of other examples there too, but this at least covers the basics.

Invoke hangs when peer container irrelevant to endorsing is stopped.
I’m not sure if it’s a bug, something I did wrong, or just-is by design.
Thanks for looking into it!
Current Setup: BYFN Solo Network
Simulation:
- query and invoke using service discovery
- I stop peer container (docker stop peer0.org1.example.com)
- Query still works fine
- Invoke HANGS forever
My Reasoning is:
Discovered peers are only 3 (through network discovery)
But, eventing peers are 4 (when called within channel.sendTransaction())
1 event still waiting for reply to be completed
Is this the reason or am I doing something wrong?
I believe that network discovery should also refresh the peer list of channel.getPeers()

would probably give best results
rickr (Wed, 22 May 2019 12:27:28 GMT):
@chill37 By default the sdk will listen to all eventing peers on the channel. The sendTransaction _by default_ will wait on all eventingPeers to see the block with the transaction. You can change that and specify on that method specific peers, or no peers at all just send it to the orderer. If a peer does not report like in your case the sdk continues to try to connect and block events in the case it just a network glitch or temporary issue with the peer. Given a network is involved their can't be any guarantee a peer will report. On the future can set a timeout. Your application needs to know how it should do recovery.

chill37 (Wed, 22 May 2019 12:31:17 GMT):
@rickr I see. So you are saying this result is by design.
In case one peer is lost for quite some time, wouldn't it be nice for sendTransaction() to have an option such as 'wait only on peers who participated on Proposal', namely the peers in proposal response? Just a thought.
chill37 (Wed, 22 May 2019 12:46:02 GMT):
anyway, thanks for making it clear! I wasn't so sure if I was doing anything wrong :joy:
rickr (Wed, 22 May 2019 12:48:25 GMT):
I think it's a situation where the sdk is caught in the middle. There is never IMO going to be a behavior that every application is going to like. You do know the peers that endorsed. You should be able to specify them on the sendTransaction
chill37 (Wed, 22 May 2019 12:51:51 GMT):
yes. now that I'm sure, I'll have to implement it. Thanks as always!

Is it possible to use the fabric java sdk with JDK 1.7?
Antimttr (Thu, 23 May 2019 14:40:24 GMT):
@rickr does the java sdk have any facilities to help adding an org to a channel? specifically can you create teh channel update difference pb/json files? Also can it perform the signature on those files? if there's any example code for these processes please let me know
rickr (Thu, 23 May 2019 14:45:07 GMT):
Updating a channel is listed in the README.md.
Antimttr (Thu, 23 May 2019 14:54:53 GMT):
right that has updating a channel configuration but specifically for the tasks needed to add an org to teh channel you have to use this command: `jq -s '.[0] * {"channel_group":{"groups":{"Application":{"groups": {"Org3MSP":.[1]}}}}}' config.json ./channel-artifacts/org3.json > modified_config.json` or something like it
Antimttr (Thu, 23 May 2019 14:55:16 GMT):
would i still need to run this command externally? or does the sdk provide facilities for performing the same action?
Antimttr (Thu, 23 May 2019 14:56:05 GMT):
seems like the jq command and the cryptotxgen commands will need to be run externally if im not mistaken?
Antimttr (Thu, 23 May 2019 14:56:05 GMT):
seems like the jq command and the configtxgen commands will need to be run externally if im not mistaken?
Antimttr (Thu, 23 May 2019 15:21:22 GMT):
So after reading https://hyperledger-fabric.readthedocs.io/en/release-1.4/channel_update_tutorial.html multiple times I have formulated a multi step proccess for creating a new org and joining it to a channel:
Antimttr (Thu, 23 May 2019 15:22:20 GMT):
1. create the new org's crypto artifacts using cryptogen from base artifact files
Antimttr (Thu, 23 May 2019 15:22:49 GMT):
2. modify and update the channel with the new crypto material generated in step 1
Antimttr (Thu, 23 May 2019 15:22:49 GMT):
2. modify and update the channel config with the new crypto material generated in step 1
Antimttr (Thu, 23 May 2019 15:23:56 GMT):
3. configure leader elections on the new org's peers and join them to the channel
Antimttr (Thu, 23 May 2019 15:24:44 GMT):
4. update the channels chaincode with the new policy which includes the new organization
Antimttr (Thu, 23 May 2019 15:24:44 GMT):
4. update the channels chaincode with the new policy which includes the new organization (this would constitute a new version of the chaincode on the channel)
Antimttr (Thu, 23 May 2019 15:25:32 GMT):
@rickr let me know if im missing anything
Antimttr (Thu, 23 May 2019 15:26:43 GMT):
seems like step one will still require the running of cryptogen which is not something the sdk deals with
Antimttr (Thu, 23 May 2019 15:27:42 GMT):
and step 2 modifying the json configuration would be something best left to the jq utility, in the example sdk code they make a very simple modification, replacing a value of an existing json key with a different value. but adding a new org is going to be a lot more modification than that
Antimttr (Thu, 23 May 2019 15:28:22 GMT):
@rickr have you ever performed all this with just the sdk only? or would you use the external tools as well?
rickr (Thu, 23 May 2019 15:49:21 GMT):
@Antimttr I have not. (honest!) The SDK does provides the means to send channel updates blocks which is needed. It admittedly keeps it simple (changing batch timeout) to keep the test and example simple. The change requires modifying json representation for changes. How the application does that is not up to the SDK. For any details on specific changes I don't feel its up to each SDK to document. Fabric documentations needs to provide and give help in appropriate rocket chat channel #fabric-questions .
Antimttr (Thu, 23 May 2019 15:52:28 GMT):
one thing i've noticed is that the doc i linked above uses command line configtxlator, where as the sdk example uses an RESTful API version of it running in a docker image. I'm curious how i could translate the commands in the doc to API calls that you use in the SDK example
Antimttr (Thu, 23 May 2019 15:52:47 GMT):
i suppose theres a document somewhere on how to use the configtxlator docker image api somewhere
Antimttr (Thu, 23 May 2019 15:52:47 GMT):
i suppose theres a document somewhere on how to use the configtxlator docker image api
Antimttr (Thu, 23 May 2019 15:55:37 GMT):
actualy the doc uses configtxgen not configtxlator
rickr (Thu, 23 May 2019 15:56:08 GMT):
I _think_ the REST APIs are limited to what's shown in the JSDK which is to get a json representations and update blocks which is shown to do the changes.
Antimttr (Thu, 23 May 2019 15:57:52 GMT):
ok i think i found the doc for the api here: https://hyperledger-fabric.readthedocs.io/en/release-1.4/commands/configtxlator.html

Antimttr (Thu, 23 May 2019 18:53:53 GMT):
@rickr in order to join the peers of a newly added org to the channel we have to pass it the genesis block. Using peer commands you do this: `peer channel join -b mychannel.block` I was looking for some equivalent option in
Antimttr (Thu, 23 May 2019 18:53:53 GMT):
@rickr in order to join the peers of a newly added org to the channel we have to pass it the genesis block. Using peer commands you do this: `peer channel join -b mychannel.block` I was looking for some equivalent option in `channel.joinPeer()` but i couldn't find a way to specify a block to pass in. do you know if there is a way of doing this with the jsdk?
Antimttr (Thu, 23 May 2019 18:55:23 GMT):
or does this command automatically grab the genesis block on the channel as part of its regular operation?
Antimttr (Thu, 23 May 2019 18:56:55 GMT):
looking at the decompiled byte code i do see that it is grabbing the genesis block: `this.genesisBlock = this.getGenesisBlock(orderer);`
Antimttr (Thu, 23 May 2019 18:57:22 GMT):
so maybe i dont need to pass it explicitly
rickr (Thu, 23 May 2019 19:41:00 GMT):
just use the joinPeer command the sdk has

HFClient
nitishbhardwaj19 (Fri, 24 May 2019 13:16:00 GMT):
@rickr & @Antimttr Just went through docs again and found that there is a method, * loadChannelFromConfig(String channelName, NetworkConfig networkConfig)* I guess that should do the job. Let me give it a shot
nitishbhardwaj19 (Fri, 24 May 2019 13:16:33 GMT):
Oh, the method is in HFClient class in case someone wants to know it.

kevinkbc (Fri, 24 May 2019 13:19:10 GMT):

Or there is some way to retry using chaincode?
nitishbhardwaj19 (Fri, 24 May 2019 13:51:28 GMT):
@Jelle.Diet Why does it requires to set UserContext just to load channelConfig?
nitishbhardwaj19 (Fri, 24 May 2019 13:54:05 GMT):
All I wanted is to initial HFClient first with all the configured channels and get it ready to be injected as a Bean dependency. I was planning to set the UserContext in all the subsequent requests for performing operation.
rickr (Fri, 24 May 2019 14:11:07 GMT):
There is _no magic_
You need to get enough valid endorsements and keep trying
Once enough endorsements have been obtained, send them to the Orderer.
If you don't observe via the peer eventing or querying for the transaction and fiind that the transaction is valid ... you need to start over with getting endorsements again. rinse, repeat till successfull

nmutter (Mon, 27 May 2019 09:36:34 GMT):
Hey, I want to setup Peers in different organizations. Therefore, each org will have an own client. I'm searching for instructions on how to create java-sdk-clients for this distributed setup. Like how would a channel creation work with multiple clients? Do all need to use the same serialized channel, or can they create it on their own?...? I just know samples where one client controls all the peers. Would be great if someone has experience with this :)

balamcyril (Mon, 27 May 2019 13:23:16 GMT):
In fabric-sdk-java implementation of idemix credentia, i don't see when the user is generate a fresh credential before sending the transaction to the peer or orderer. we just see when the user credential is set in user trasaction without any other generation step
Jelle.Diet (Mon, 27 May 2019 13:27:19 GMT):
The user gets his keys and certificate when enrolling, which are then used by the HFClient to send the transaction
balamcyril (Mon, 27 May 2019 13:36:38 GMT):
yes i see this step and i understand that part. but idemix credential is provide anonymity and unlinkability for user during this authentication with the MSP. i get this answer from @mastersingh24 " this credential is actually not used to submit transactions. What actually happens is that the client generates a fresh credential from the enrollment credential and uses that to submit transactions", the i want to know when and where this step is done

if i have a net with 4 peer, then one of them crash down ... how can i get him in to network again?
if this peer stand up again ( it have same name, ip, ports...) why dont login in net?
I get to join again this peer to channel, but chaincodes are not present when i put peer chaincode list --installed . Must i update my channel?
I am using java sdk 1.3
nitishbhardwaj19 (Wed, 29 May 2019 06:14:40 GMT):
It is advisable to use volume mounts such that a peer can resume from the state it went off.
AndresMartinezMelgar.itcl (Wed, 29 May 2019 06:16:59 GMT):
sure, but i dont know if is posible make a volume mounts from /
nmutter (Wed, 29 May 2019 10:26:19 GMT):
push - can someone give me a hint to where to look? I have no problem setting up a network with just one client (which knows all peers and peeradmin accounts), but in reality the parties dont give me their peeradmin account. So the setup has to work distributed and I do not know how
AndresMartinezMelgar.itcl (Wed, 29 May 2019 11:08:29 GMT):
Hi i am trying to upgrade version from 1.0 to 2.0 of my chaincode, but i am receiving this proposal--> 3 are OK and 1 failed( allways fail this one)

I have a 3 Org network. Org1 and Org3 form a PDC. When I invoke a transaction, I get the error:

sejalpawar (Thu, 30 May 2019 10:18:05 GMT):
How can I stop Org2 from getting the transaction request? Org2 is not an endorsing peer as per my endorsement policy in yaml file.
sejalpawar (Thu, 30 May 2019 10:18:52 GMT):
But channel.sendTransaction() issues transaction to all peers on channel irrespective of endorsement policy
bestbeforetoday (Thu, 30 May 2019 14:41:26 GMT):
@sejalpawar You can specify a collection of peers to which the proposal should be sent as a second argument to `Channel.sendTransactionProposal()`. Or if you have discovery enabled then perhaps `Channel.sendTransactionProposalToEndorsers()` might work better
sejalpawar (Thu, 30 May 2019 15:03:35 GMT):
@bestbeforetoday I was able to send the request to selected peers but now the block is not being persisted in the chain i.e. the changes made in the transaction are not being reflected
sejalpawar (Thu, 30 May 2019 15:05:54 GMT):
Endorsement Policy: identities:
user1: {"role": {"name": "peer", "mspId": "Org1MSP"}} # role member in org with mspid Org1MSP
user2: {"role": {"name": "peer", "mspId": "Org2MSP"}}
user3: {"role": {"name": "peer", "mspId": "Org3MSP"}}

#- signed-by: "user2"

Antimttr (Thu, 30 May 2019 15:07:51 GMT):
yeah if you want it on the chaincode you need to send it to orderers
Antimttr (Thu, 30 May 2019 15:08:00 GMT):
just like you did if you setup a channel configuration change
Antimttr (Thu, 30 May 2019 15:08:05 GMT):
send it to peers first, then orderers
sejalpawar (Thu, 30 May 2019 15:08:55 GMT):
Collection responses = mychannel.sendTransactionProposal(request, peer);
sejalpawar (Thu, 30 May 2019 15:08:57 GMT):

sejalpawar (Thu, 30 May 2019 15:09:32 GMT):
I have
Antimttr (Thu, 30 May 2019 15:12:28 GMT):
are you checking the responses to ensure its actually working?
sejalpawar (Thu, 30 May 2019 15:13:09 GMT):
yeah they return success
Antimttr (Thu, 30 May 2019 15:13:14 GMT):
you hsould be able to count the endorsements on the invocation
sejalpawar (Thu, 30 May 2019 15:23:06 GMT):
hey solved! Had to add cf.join() instead of Thread.sleep() post sendTransaction()
sejalpawar (Thu, 30 May 2019 15:23:10 GMT):
Thank you
sejalpawar (Thu, 30 May 2019 15:23:45 GMT):
I am confused though.. why does the function getEndorsingPeers() send request to add peers on the channel?
sejalpawar (Thu, 30 May 2019 15:23:45 GMT):
Endorsement Policy: identities:
user1: {"role": {"name": "peer", "mspId": "Org1MSP"}} # role member in org with mspid Org1MSP
user2: {"role": {"name": "peer", "mspId": "Org2MSP"}}

# - signed-by: "user1"
#- signed-by: "user2"
- signed-by: "user3"
sejalpawar (Thu, 30 May 2019 15:23:45 GMT):
Oh, I left it for default values. I am guessing the default is true..
sejalpawar (Thu, 30 May 2019 15:23:52 GMT):
all* peers
Antimttr (Thu, 30 May 2019 15:24:11 GMT):
are all your peers set as endorsers?
Antimttr (Thu, 30 May 2019 15:24:13 GMT):
in the network-config
sejalpawar (Thu, 30 May 2019 15:24:50 GMT):
No.. Endorsement Policy: identities:
user1: {"role": {"name": "peer", "mspId": "Org1MSP"}} # role member in org with mspid Org1MSP
user2: {"role": {"name": "peer", "mspId": "Org2MSP"}}

# - signed-by: "user1"
#- signed-by: "user2"
- signed-by: "user3"
sejalpawar (Thu, 30 May 2019 15:25:24 GMT):
this is the endorsementPolicy.yaml
Antimttr (Thu, 30 May 2019 15:25:44 GMT):
right, but what about in your network config under channel
Antimttr (Thu, 30 May 2019 15:25:50 GMT):
thats where the roles for the peers are defined
Antimttr (Thu, 30 May 2019 15:26:08 GMT):
```
peer1.org1.example.com:
endorsingPeer: false
chaincodeQuery: true
ledgerQuery: true
eventSource: false
```
Antimttr (Thu, 30 May 2019 15:26:11 GMT):
like that
sejalpawar (Thu, 30 May 2019 15:27:30 GMT):
Oh, I left it for default values
sejalpawar (Thu, 30 May 2019 15:27:37 GMT):
I am guessing the default is true
Antimttr (Thu, 30 May 2019 15:27:56 GMT):
if thats the case then all your peers on the hcannel would be defined as endorsers
Antimttr (Thu, 30 May 2019 15:28:06 GMT):
and thats why they're all getting sent the transaction
sejalpawar (Thu, 30 May 2019 15:28:37 GMT):
got it
Antimttr (Thu, 30 May 2019 15:29:02 GMT):
im still a bit confused as to what actually references the network-config.yaml
Antimttr (Thu, 30 May 2019 15:29:22 GMT):
doesnt seem like the nodes actually reference the artifacts directory, other than for cypto assets
Antimttr (Thu, 30 May 2019 15:29:30 GMT):
but maybe i just missed it
sejalpawar (Thu, 30 May 2019 15:30:12 GMT):
Can you point me to where I can find the endorsingPeer setting? as in a sample config file
Antimttr (Thu, 30 May 2019 15:30:25 GMT):
network-config.yaml
Antimttr (Thu, 30 May 2019 15:30:28 GMT):
is where i got that from
Antimttr (Thu, 30 May 2019 15:30:38 GMT):
that one is from the balance-transfer sample
Antimttr (Thu, 30 May 2019 15:31:02 GMT):
im looking for the same file in the first-network sample and i cant locate it
sejalpawar (Thu, 30 May 2019 15:31:44 GMT):
I will try adding the line in docker-compose definition peers?
sejalpawar (Thu, 30 May 2019 15:31:44 GMT):
I will try adding the line in docker-compose definition of peers?
Antimttr (Thu, 30 May 2019 15:31:59 GMT):
```
The network connection profile provides client applications the information about the target
# blockchain network that are necessary for the applications to interact with it. These are all
# knowledge that must be acquired from out-of-band sources. This file provides such a source.
```
Antimttr (Thu, 30 May 2019 15:32:09 GMT):
so thats from the top of one of the network-config's
Antimttr (Thu, 30 May 2019 15:32:22 GMT):
i guess afaict network-config isnt actually used by the nodes at all
Antimttr (Thu, 30 May 2019 15:32:27 GMT):
and is just for your client to reference
Antimttr (Thu, 30 May 2019 15:33:29 GMT):
im guesssing, not sure about this but im guessing that you're supposed to refer to them when you join a peer to a channel and give it this command:
Antimttr (Thu, 30 May 2019 15:33:33 GMT):
```
channel.joinPeer(peer, Channel.PeerOptions.createPeerOptions()
.setPeerRoles(EnumSet.of(Peer.PeerRole.ENDORSING_PEER, Peer.PeerRole.LEDGER_QUERY,
Peer.PeerRole.CHAINCODE_QUERY, Peer.PeerRole.EVENT_SOURCE)));
```
Antimttr (Thu, 30 May 2019 15:34:00 GMT):
so then you would read that network-config.yaml and figure out which of those values to set for setPeerRoles()
Antimttr (Thu, 30 May 2019 15:34:20 GMT):
i think ill need to fix that in my implementation
sejalpawar (Thu, 30 May 2019 15:35:49 GMT):
I just commented out the endorsement file line while instantiating the chaincode.. and its absense doesnt seem to make any difference
Antimttr (Thu, 30 May 2019 15:36:49 GMT):
right because i think nothing actually refers to that file
Antimttr (Thu, 30 May 2019 15:36:57 GMT):
your app is supposed to when it gives that command above
Antimttr (Thu, 30 May 2019 15:37:05 GMT):
and THAT is when the actual roles for the peers are established
Antimttr (Thu, 30 May 2019 15:37:43 GMT):
are you joining your peers via the sdk or did you one run of those sample scripts to do it?
sejalpawar (Thu, 30 May 2019 15:37:50 GMT):
sdk
Antimttr (Thu, 30 May 2019 15:38:01 GMT):
so what does your joinPeer() call look like?
sejalpawar (Thu, 30 May 2019 15:38:47 GMT):
peer[i][j] = client.newPeer(peerName, "grpcs://localhost:"+String.valueOf(portNo), peerProperties);
mychannel.joinPeer(peer[i][j]);
Antimttr (Thu, 30 May 2019 15:39:34 GMT):
so you arent setting peer options...
Antimttr (Thu, 30 May 2019 15:39:40 GMT):
or is that what you're calling peerProperties
sejalpawar (Thu, 30 May 2019 15:40:04 GMT):
No, my peer properties is just for TLS
sejalpawar (Thu, 30 May 2019 15:40:16 GMT):
I am not explicitly setting peer roles
Antimttr (Thu, 30 May 2019 15:40:20 GMT):
right, so maybe its using some defaults then
Antimttr (Thu, 30 May 2019 15:40:28 GMT):
internal defaults to the sdk
Antimttr (Thu, 30 May 2019 15:40:59 GMT):
i went off of the end2end example
Antimttr (Thu, 30 May 2019 15:41:05 GMT):
and they explicitly set peeroptions
sejalpawar (Thu, 30 May 2019 15:42:28 GMT):
Oh okay got it
sejalpawar (Thu, 30 May 2019 15:44:08 GMT):
also, maybe we can create a jira for private data example where in an org is not part of the PDC?
Antimttr (Thu, 30 May 2019 15:47:17 GMT):
yeah i havent messed around with private data much
Antimttr (Thu, 30 May 2019 15:47:30 GMT):
not sure that ill be using it in my application

@Antimttr if I send proposal requests to all peers, collect responses and send only successful responses to orderer would that work?
Antimttr (Thu, 30 May 2019 15:59:57 GMT):
yeah, i dont think sending uncessful requests to the orderers works
Antimttr (Thu, 30 May 2019 15:59:57 GMT):
yeah, i dont think sending unsuccessful requests to the orderers works
sejalpawar (Thu, 30 May 2019 16:00:27 GMT):
okay
Antimttr (Thu, 30 May 2019 16:00:39 GMT):
yeah i put all the successes into their own data structure
Antimttr (Thu, 30 May 2019 16:00:44 GMT):
and only pass those to the orderers
Antimttr (Thu, 30 May 2019 16:01:24 GMT):
though, if i get any failures that also is a breaking condition for my function
sejalpawar (Thu, 30 May 2019 16:02:30 GMT):
Hmmm... we could check for something like 2 out of 3 responses and pass it to orderer
Antimttr (Thu, 30 May 2019 16:03:04 GMT):
im not using dynamic network though
Antimttr (Thu, 30 May 2019 16:03:09 GMT):

I understand. What I don't have is an example or instructions, on how these "own clients" should be implemented to create and join a channel. My first challenge was, to test if my peer is already in a channel, if not I want to join it. But the channel may not exist, so if it does not exist I will create it. I really am doing try and error and not really know where I could find the informations/examples for how to do this best.

@nmutter You've used the examples that ship with the Java SDK right?
If you take a look at them, you'll see that the network that comes with it is a 2 org network. In the End2EndIT.java test the client basically loops through all of the organizations, however I believe that in the real world this wouldn't be possible. (Ie. https://github.com/hyperledger/fabric-sdk-java/blob/519cc0a44c90eb84276a8104b805f9053ca073c9/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java#L162)
When it runs the fabric test it actually only uses a single organization though ( https://github.com/hyperledger/fabric-sdk-java/blob/519cc0a44c90eb84276a8104b805f9053ca073c9/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java#L205 )
So, what I _think_ you can do, is basically have two different client applications where one of them uses the credentials for Org1 and the other for Org2 and then do all the transacting you want with the network. Does that make sense?
In a real world application (like Ford/GM), they wouldn't be sharing user credentials with one another. So each client would only have access to the credentials that belong to the respective organizations.
rickr (Tue, 04 Jun 2019 12:39:05 GMT):
@tballast @nmutter Just to add the new Lifecycle example better shows two different orgs cooperating but this is not at all realistic within a single instance of an application. https://github.com/hyperledger/fabric-sdk-java/blob/519cc0a44c90eb84276a8104b805f9053ca073c9/src/test/java/org/hyperledger/fabric/sdkintegration/End2endLifecycleIT.java
nmutter (Tue, 04 Jun 2019 13:06:50 GMT):
thanks @tballast I used the End2EndIT.java for most of my work till now. The End2endLifecycleIT does look more pormising as it basically uses two clients for two orgs, thanks @rickr . I searched such an example for 1.4, but could not find it (and still cant :) ).

You are right @rickr I checked the cert file. Certificates were generated with the name as orderer.example.com
nitishbhardwaj19 (Thu, 06 Jun 2019 20:13:21 GMT):
@rickr I agree, but won't these clients still shares some details about the Org? Like Peers details of different Org which needs to be joined to a channel.
nitishbhardwaj19 (Thu, 06 Jun 2019 20:25:08 GMT):
@Antimttr @rickr If we create peer on the fly(without defining config in network-config.yaml), and join those peers to the channel. Will Channel object be able to figure out who all are endorsing peers at the time of TransactionProposals being sent by its own? Or will it send the proposal to all the peers who has joined the channel?

@rickr @Antimttr @Jelle.Diet Thanks for all your help guys. I have integrated SDK with a HLF network. It's working as expected. I just have one doubt, how do I on-board a new Org? I know that we are suppose to have 1 HFClient per org, but what if I want to host a new instance of SDK for the org who is on-boarding the network. If I do so, how would I add peers of the org which is already a participant to the new orgs HFClient? It would be really great if someone can share their experience with adding a new Org, really appreciate guys

@nitishbhardwaj19 chaincodePath would be like your GO path in that input stream as if it were on a filesystem no difference.

@nitishbhardwaj19 add vs join is mentioned in the README.md

nitishbhardwaj19 (Mon, 10 Jun 2019 11:54:10 GMT):
Thanks for replying, I understand the difference between add and join. I just wanted to know what if we are running two instances of SDK, one per org. In that case, how would we enforce that HFClient is in sync with channel information about the peers.

Javi (Mon, 10 Jun 2019 14:27:18 GMT):
Hi people! :grinning: I created a chaincode that saves a struct of 6 integers, and I developed a middleware in java using the fabric sdk to write data to the ledger using spring, each request takes ~2 sec to complete, is this normal? how I can reduce this time? I'm using tls on all conections, but 2 seconds is much time for a simple write of 6 values... any idea?
rickr (Mon, 10 Jun 2019 14:50:33 GMT):
Don't follow your question. Know what peers to connect to is out of bound information. You can use service discovery to help with that but even there you'll need to know at least one peer that will be doing the service discovery
Javi (Mon, 10 Jun 2019 15:00:16 GMT):
I measured time to complete in proposal and transaction, these are the results
```
Transaction proposal takes 69 ms to finish
Send transaction takes 2250 ms to complete
```
Javi (Mon, 10 Jun 2019 15:00:36 GMT):
I'm testing with a test org with only 1 peer, in my local machine....
nitishbhardwaj19 (Mon, 10 Jun 2019 15:08:38 GMT):
Right, I am sorry for not being clear. Let me re-phrase the question. I have 1 SDK instance which has singleton HFClient. I add Peers, Orderer to HFClient and create a channel and jointhese peers to the Channel. Now, the problem is, that if I am running another instance of SDK for another ORG, how will this org can refresh it's HFClient details like peers of a channel if Org1 adds another peer to the same channel. The channel at network level will definitely have the information about joined peers, but since there are 2 copies of HFClient which has a channel representation needs to be in sync as well.
rickr (Mon, 10 Jun 2019 17:38:54 GMT):
If you don't use service discovery there's no *magic*. Another organization will need _out of bounds_ inform you it running (or not) a new peer in another location. The only reason you would care is to get an endorsment from that peer's organization. Generally just having one is sufficient. Having more than one peer form another organization would give you redundancy and/or possible load sharing.
nitishbhardwaj19 (Mon, 10 Jun 2019 19:28:45 GMT):
Sure, Thanks @rickr.

bestbeforetoday (Wed, 12 Jun 2019 09:48:32 GMT):
I think by default send transaction will, in addition to sending the transaction to the orderer, also wait to receive commit events from all the eventing peers in the network, which can take a while. You can configure different wait options (including not waiting for commits to happen on peers) depending on your performance and consistency requirements.

yes relative to where you package .. look at running end2endIT in a debugger you'll see how it's set there.
aatkddny (Thu, 13 Jun 2019 00:15:46 GMT):
@rickr - Are there any significant changes to the network configuration json for 1.4.1 vs 1.4 when moving to raft. If I self-generate the same network configuration as I have for a kafka setup will a channel.loadFromNetworkConfig still work or are there gotchas you can think of off the top of your head? I'm going to have to suck it and see, but figured I'd try to save some time.
TIA.
rickr (Thu, 13 Jun 2019 13:32:24 GMT):
@aatkddny I have not tested with Raft. The SDKs _should_ not care what's implementing the Orderer. IMO if it does, it would be a bug on the Fabric side.

I guess you need to configure all the related certs to work with TLS enabled network when you add Orderer and peers to HFclient

Hi Anyone please suggest me which SDK is best for development?
Antimttr (Fri, 14 Jun 2019 18:39:56 GMT):
well depends on what language you're comfortable with
Antimttr (Fri, 14 Jun 2019 18:40:27 GMT):
i'd say objectively the Golang sdk is going to have the most features and always most up to date, since I beleive that is the primary sdk, with node and java close behind
davidkel (Fri, 14 Jun 2019 18:50:08 GMT):
@Antimttr @hanubc7743 the Go SDK has never been officially released, there are only alpha versions. The fabric documentation does say that the only 2 official sdks are node and java. This is mentioned in several places in the docs (although the docs are obviously out of date in that respect as they mention the rest sdk which doesn't exist anymore). Node has the new fabric-network api, but java will get that soon. Java on the other hand has support for IDEMIX and is the only sdk that has that, so if you need IDEMIX then you will have to use the Java SDK.

interesting, thanks for the info
hanubc7743 (Fri, 14 Jun 2019 19:58:26 GMT):
@Antimttr @davidkel all SDK's supporting all features or is there any diffrence
Antimttr (Fri, 14 Jun 2019 19:59:26 GMT):
java for idemix, nodejs for fabric-network api. that's the main difference in feature set

bestbeforetoday (Wed, 19 Jun 2019 14:47:52 GMT):
There isn't anything different about how you use the _fabric-gateway-java_ API with TLS and non-TLS networks. And how you use TLS with _fabric-gateway-java_ is no different to how you use it with other client APIs. The differences are in the Fabric network configuration. So the connection profile needs to have appropriate certificate information, for example:
https://raw.githubusercontent.com/hyperledger/fabric-gateway-java/master/src/test/java/org/hyperledger/fabric/gateway/connection-tls.json
And appropriate tls options need to specific when using the `peer` command to create, join and update channels (e.g. `--tls true --cafile cert.pem`), and using the `peer` command for chaincode install and instantiate

rickr (Mon, 24 Jun 2019 12:29:58 GMT):
If you've written a variable in chaincode You'll need to wait for that to be sent to orderer then wait till the future is resolved before reading/modifying it again.
rickr (Mon, 24 Jun 2019 12:31:38 GMT):
Chaincode get's instantiated. I don't know what you mean by Peers and Orderers being instantiated.
balamcyril (Mon, 24 Jun 2019 12:35:45 GMT):
in my code i want to test how many initializatio transaction could be handle by the order, for that, i send several transaction to the orderer with different thread, to see if the orderer could handle all these transaction. Actulaly i'm just using 2 thread an it's not working
balamcyril (Mon, 24 Jun 2019 12:38:44 GMT):
for each thread i'm using different variable, so it not possible to have a collixion with different transaction
rickr (Mon, 24 Jun 2019 13:14:07 GMT):
I've had up to 400 threads changing and querying different values running for hours
rickr (Mon, 24 Jun 2019 13:24:24 GMT):
Also even if its the *same* variable you need to make sure any changes are committed to the peers before you try to do an endorsement using that variable again.
nitishbhardwaj19 (Mon, 24 Jun 2019 14:40:09 GMT):
@rickr Thanks for replying. I found an interesting jira ticket https://jira.hyperledger.org/browse/FAB-11834. I don't know why, but one of my peer is unreachable when I use TLS. As this Jira ticket suggests, it is expected. I am handling this at code now. Though I am still not sure about why Peer is unreachable in TLS mode. I am just using hostnames and gprcs protocols.
rickr (Mon, 24 Jun 2019 15:41:55 GMT):
Google
`openssl s_client -connect`
try to connect to the same peer with that.

Coada (Tue, 25 Jun 2019 10:49:34 GMT):
Hello! I am using the Java SDK 1.4.1 to interact with my Fabric network setup using Docker (Compose). My setup consists of 2 peers and one OSN, all part of a channel with instantiated chaincode. I am now testing what happens if one peer goes down, by stopping the docker container. I execute a function in the chaincode and get 1 valid (from the online peer) and 1 invalid (from the offline peer) proposalResponses. I send the valid response to the OSN, however *waiting on the future blocks indefinitely*. If I query the online peer, I can confirm that the transaction has gone through. Is there any way I can get the future to return?
rickr (Tue, 25 Jun 2019 11:25:56 GMT):
When dealing with networking your future should have some timeout. If it does timeout, your application can decided it's own recovery strategy. Report the error to user, Query peers for each transaction to see if it's done.
Coada (Tue, 25 Jun 2019 12:03:30 GMT):
Hello rickr, thanks for your reply. I have now added a timeout. I am also looking into adding TransactionOptions to the request, and setting the future to return when `X` peers have seen it where `X` is the size of the proposalResponses. What is the difference between `createNoEvents().setN()` and `createNofEvents().setN()`?
Coada (Tue, 25 Jun 2019 13:01:50 GMT):
Nvm I solved it. createNoEvents() is the same as _no_ events, while createNofEvents is number of events. It is clear now that I am looking at it - however perhaps some Javadoc can be added to these methods to differentiate them a bit more?

None in the core sdk. There is a Java programming model work in progress that I think has something like that. The SDK does does show storing credentials as properties files in the integration tests.

Hi Guys, anyone here know why we get only one orderer when querying the network like `mychannel.getOrderers()`. The network is running raft orderer service with 5 orderer node. Does it only consider the leader node?
yeousunn (Fri, 28 Jun 2019 02:53:21 GMT):
Even `mychannel.getPeers()` is giving me only 1 peer, it should be 4 in total and 2 per organization. Is there anything that I need to configure to get the correct result?
yeousunn (Fri, 28 Jun 2019 03:07:04 GMT):
Ok, This is based on number of orderers/peers I specify in the configuration file. not the actual count of nodes.
bestbeforetoday (Fri, 28 Jun 2019 08:07:44 GMT):
If you configure your client to use discovery (which requires the network to be configured in a suitable manner with anchor peers etc.), you should be able to specify a minimal set of peers in your common connection profile, and it should discover all the other nodes in the network when you call initialize() on the channel object.
yeousunn (Fri, 28 Jun 2019 08:10:59 GMT):
Thank you for the reply. I am using the first-network sample right now. Is there any specific document related to that?
bestbeforetoday (Fri, 28 Jun 2019 08:44:29 GMT):
The steps for set up of the first-network at https://hyperledger-fabric.readthedocs.io/en/release-1.4/build_network.html do mention configuring anchor peers, so things might be OK from that end. With the Java SDK, there needs to be a channel in the connection profile, and that channel needs to reference a peer that has `"discover": true` in its list of roles
yeousunn (Fri, 28 Jun 2019 08:46:30 GMT):

Is there a way to pull the registered users as well as their secrets from the CA?
I have a client application that, on first boot, enroll an Admin, then register and enroll a user. I can save this user locally and then reboot the client and everything is OK. However, if I don't save the user locally, then I have no way of using this user as everytime I try to enroll it to get the secret, I get an error saying it already exists. When I call `HFCAClient.getHFCAIdentities(adminUser);` I can see the user is enrolled with the network, however the secret property is empty. Is there a way to obtain it?

I'm not rick, but just as an fyi you can start it as a service locally - it comes up on 7059 as a default. Or you can use a processbuilder to run it in a shell. i'm told there's a k8s container available for it too but i haven't got round to trying that yet.

`parseGrpcUrl` in `org.hyperledger.fabric.sdk.helper.Utils` requires `throw new RuntimeException("URL must be of the format protocol://host:port. Found: '" + url + "'");` This doesn't work so well with an ingress if I set the path to /{service}.
Anyone have a workaround?

Hello Guys, I am following the service discovery from this link https://github.com/hyperledger/fabric-sdk-java/blob/release-1.4/src/test/java/org/hyperledger/fabric/sdkintegration/ServiceDiscoveryIT.java but I am unable to discover peers, I should get count 4 but I am getting only one. I noticed that it say I need to add entries into host file. is it necessary for all network? I am using the first-network for the test. I am using version 1.4

Anyone manage to get this working with TLS on? Is client TLS a requirement or have I stuffed something up?

Has anyone manage to get this working with TLS on inside Kubernetes?
I've been fine up until the 1.4.1 release using Kafka - well fine is relative. Kafka has presented some issues.
We need to move to raft ordering.
Raft requires TLS.
Fabric is moving to Kubernetes native (finally).
I can't find a way to talk to my peers with TLS on.
I can't use an ingress because of the problem I described above - note TODO:
```
Properties props = new Properties();
Pattern p = Pattern.compile("([^:]+)[:]//([^:]+)[:]([0-9]+)", Pattern.CASE_INSENSITIVE);
Matcher m = p.matcher(url);
if (m.matches()) {
props.setProperty("protocol", m.group(1));
props.setProperty("host", m.group(2));
props.setProperty("port", m.group(3));
String protocol = props.getProperty("protocol");
if (!"grpc".equals(protocol) && !"grpcs".equals(protocol)) {
throw new RuntimeException(format("Invalid protocol expected grpc or grpcs and found %s.", protocol));
}
}
else {
throw new RuntimeException("URL must be of the format protocol://host:port. Found: '" + url + "'");
}
// TODO: allow all possible formats of the URL
```
I can't get a NodePort (which is how everything is exposed now) to work. I don't believe I can use GRPCS with NodePorts.
The last resort I have is to try to stick my code inside the K8S cluster, but that restricts me to a single cluster - which isn't realistic long term.
Anyone have a workaround?
mattremy (Wed, 03 Jul 2019 17:18:15 GMT):
A very basic question... What is the difference between creating an identity and registering and enrolling an identity? Even when an identity, it does get registered?
dan13 (Wed, 03 Jul 2019 19:09:49 GMT):
Host file entries are needed to map logical names to IP addresses when there is no name server. On a real network with DNS there would be no need to set host file entries.
dan13 (Wed, 03 Jul 2019 19:16:10 GMT):
You create the identity in CA and then enroll the identity. Enrollment returns the PK and cert needed to sign transactions as that identity. This may help: https://stackoverflow.com/questions/49917351/cas-enrollment-registration-for-hyperledger-fabric

no, still have the problem. only reply I get from people is to configure anchor peer and enable discovery. I have done both and followed the example. Still not able to discover other nodes.

You have the peer your client connects to configured for service discovery? In your network config json you want to set the "discover" attribute to true for your peer. Also, Looking at org.hyperledger.fabric.sdk.Channel class and debugging into it should help you figure out what is going on.

not completely solved. from the description, you find the endorser by using service discovery. However, your problem is with raft order. it is a little strange.

I am using the default first-network sample. I have enabled discovery on all peers using the following property in docker environment `CORE_PEER_DISCOVERY_ENABLED=true` for all peers. External Endpoints are already configured in the sample.

Each orderer's container has a dedicate internal port and the same external port 7050, and i think that the setting is correct.

So the problem is an ssl issue where it eventually throws `java.io.IOException: No extension found with name NetscapeCertType`
There's a handshake failure on the peer.
The properties coming in to the endpoint have two values: `pembytes` and `org.hyperledger.fabric.sdk.peer.organization_mspid`
The properties I build to talk to a peer have a few more properties in there.
These to be precise `sslProvider, negotiationType, hostnameOverride, pemBytes, clientKeyBytes, clientCertBytes`
Since I *can* talk to a peer clearly one of them is required.

iramiller (Fri, 12 Jul 2019 16:25:26 GMT):
@aatkddny -- your experience sounds familiar to me. I rolled infrastructure scripts to manage all the cluster org/channel/chaincode management tasks instead of trying to use the Java (we are actually using Kotlin) SDK. I really recommend that you put components inside of the cluster that talk to HLF and expose services which can serve as proxies to the HLF interfaces that are designed to work well with your K8s load balancers and ingress. Essentially treat the HLF Java SDK like a 'resource' in your software architecture (similar to Postgres and the like). Oh and don't be afraid to fork things and modify for your needs. It really hasn't been too bad to maintain.
aatkddny (Fri, 12 Jul 2019 16:47:04 GMT):
@iramiller My next step forward is probably to dockerize my spring boot admin software and stick it into my cluster rather than having it run standalone. Which I wish I didn't have to do...
Hopefully that'll ameliorate *some* of my networking problems. The problem is that won't fix things when I need to join peers across multiple clusters. I really don't want to have to fork the SDK - keeping my own stuff working between fabric versions is enough of a chore.
It's a real shame that java is treated as a second class citizen when compared to node.

Thank you. I constructed basic-network. And deployed fabcar chaincode.
my hope is connecting this chaincode with fabric-java-sdk. But there is nothing simple sample client code.
Currently I made client code (below). Please give me an advice to complete this code.

iramiller (Fri, 12 Jul 2019 17:33:22 GMT):
Contributions are certainly helpful ... but when you disagree with core architecture such as how peers/chaincode are handled such that you fork and replace that (but not fully covering existing use cases) I am not sure that any useful code is going to get contributed back from that.

tballast (Wed, 17 Jul 2019 11:24:54 GMT):
When using the Java SDK, I wish to instantiate chaincode on a channel, and I have an endorsement policy that requires that it is endorsed by both Org1 and Org2.
I am running my client from the context of Org1, which will not know about the private keys of Org2. I set up my channel and attach the Org 1 peers as well as an Org2 peer, however it always fails the endorsement stage. In the logs of the docker containers I see the following:

How can I submit transactions as Org1, when endorsement is required by _both_ Org1 and Org2, without knowing the information from Org2? Am I missing something?

I wish to upgrade chaincode via a Java client. I am using Java chaincode.
I am _also_ upgrading via the cli. If I install the java chaincode on peer0, I need to specify a path so it installs correctly. When I install the chaincode on peer1 with the client, it forces me to make the path null.
Then, when I try to use the client to construct and UpgradeProposal, it complains that the two chaincodes are inconsistent. How is it possible to do this?

yeousunn (Fri, 19 Jul 2019 07:21:35 GMT):
Hi, I have a few channels and different number of peers joined to those channels, I am querying channel and retrieving all the peers that are joined to the channel. I can get all the peers if I have that channel configuration in yaml file. But what if I don't have configuration for the channels? Right now I get null for channel that has no configuration in yaml. Is there a way to do this without adding configuration for all channels?
yeousunn (Fri, 19 Jul 2019 08:53:36 GMT):
When I am querying peers with out discovery I am getting the following result
> FabricPeer(name=peer1.org1.example.com, url=grpcs://192.168.14.245:8051, protocol=grpcs, properties={pemFile=/home/thgy/work/hyperledger/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/server.crt, ssl-target-name-override=peer1.org1.example.com, grpc.http2.keepalive_time=15, hostnameOverride=peer1.org1.example.com})
But when I enable discovery I get
> FabricPeer(name=peer0.org2.example.com:9051, url=grpcs://peer0.org2.example.com:9051, protocol=grpcs, properties={pemBytes=[B@635fe6c2})
In place of pemFile I am getting pemBytes when discovery is enabled. I need pemFile information.

If you convert the byte array to string, what do you get?
yeousunn (Mon, 22 Jul 2019 02:11:37 GMT):
String value: {pemBytes=[B@6e1fe857}
dan13 (Mon, 22 Jul 2019 02:13:56 GMT):
that's just the byte array toString, which is from Object -- try String s = new String(bytes)
yeousunn (Mon, 22 Jul 2019 02:33:51 GMT):
That is "Properties" object.

yeousunn (Mon, 22 Jul 2019 02:37:46 GMT):
It's like this, When I have `discover: true` I get correct information for the anchor peer. but for other peers. the Properties field is Json value with some bytes.
yeousunn (Mon, 22 Jul 2019 02:47:21 GMT):
I think this as to do with config file. anchor peer information is taken from config file where as other peers are discovered.

yeousunn (Mon, 22 Jul 2019 03:01:36 GMT):
and this code` String p = peer.getProperties().getProperty("pemBytes");` returns `null`
yeousunn (Mon, 22 Jul 2019 05:34:49 GMT):
Is there a way to make Peer object using the names returned by `OrgInfo.getPeerNames();`?

What is the difference between Admin and PeerAdmin?

Antimttr (Mon, 22 Jul 2019 14:37:23 GMT):
i beleive admin is the admin cert for the ca, where as peeradmin is the actual admin account on the channel
Antimttr (Mon, 22 Jul 2019 14:38:12 GMT):
so one is for enrolling users, the other is for signing endorsements for channel config changes and the like
tballast (Mon, 22 Jul 2019 15:00:13 GMT):

darapich92 (Wed, 24 Jul 2019 09:42:32 GMT):
hi all, i have a question related to register a user in Java sdk. i called ca0 to register a user by setting the affiliation "Org1.department". i failed in registration and i saw the error message in the cmd is "Failed getting affiliation 'org1.department': Failed to get affiliation: sql: no rows in result set". Could you tell me where is the sql where stored the affiliations?
yuriiuhlanov (Wed, 24 Jul 2019 16:04:21 GMT):
please refer to the documentation https://hyperledger-fabric-ca.readthedocs.io/en/latest/users-guide.html#registering-a-new-identity. The first thing that comes to my mind is your registrar has different affiliation than that you are setting at the new client

Is the primary purpose of the NetworkConfig class to run a non-administrative client?
I am trying to use it, however if you want to actually stand a network up (Ie. create a channel from scratch, join peers to it, etc) then it seems that this not ideal. Anyone have experience with it?
tballast (Fri, 26 Jul 2019 08:53:06 GMT):
Or rather, not necessarily non-administrative, but at the very least it seems like one is unable to create a channel from scratch with the network config alone.
mahoney1 (Fri, 26 Jul 2019 10:14:18 GMT):
@tballast you would be using the Client to create channels, nodes, join peers etc from scratch ->https://sdkjavadocs.github.io/org/hyperledger/fabric/sdk/HFClient.html whereas NetworkConfig https://sdkjavadocs.github.io/org/hyperledger/fabric/sdk/NetworkConfig.html holds details of network and channel configurations of the running network, typically loaded from an external config file (eg. json, yaml etc).
tballast (Fri, 26 Jul 2019 10:20:16 GMT):
@mahoney1 I see. Yea, that makes sense, I was just wondering because even if you're using the NetworkConfig, you still need to have a client to interact with the network. However, if you want to do something like create it from scratch you need to join the peers to it, and create an orderer, but you can't pull all of this information from the NetworkConfig, just really basic stuff like names and properties (no locations or Peer Roles, etc.)
So in that case, the actual _initialization_ (construct channel, install/instantiate chaincode) of the network is fairly separate from the _interaction_ (invoke, query, etc). I thought that perhaps the yaml file could be used as a properties file for building the network from scratch, but it doesn't look like it.

If you look at the IBM Blockchain Platform (IBP) 2.0, you build everything (other than the k8s cluster) through a "blockchain console" web app. I think scripting (like byfn.sh) makes more sense for blockchain-based apps rather than blockchain-as-a-service providers (IBP) but strictly my opinion. Either way you start with some description of your desired network -- and the only requirement is that it has all the info necessary to be successful -- and use some means to instantiate it.

Does anyone know about how to solve this issue?
tballast (Fri, 02 Aug 2019 08:33:11 GMT):
you're trying to run the example twice in a row is my guess. If you tear down the network and do it again you probably won't see this error. On the first run through it registers `user1`, and on the second run it's trying to do the same, but it's already been done.
Rosan (Fri, 02 Aug 2019 08:53:58 GMT):
Has joined the channel.
tballast (Fri, 02 Aug 2019 11:18:21 GMT):
Has anyone written a java client that is used to construct a network from scratch (ie. create the channel from scratch, _join_ peers, instantiate chaincode, etc.) and if so, do you have a clean way of handling whether peers need to be added or joined?
aatkddny (Fri, 02 Aug 2019 13:06:29 GMT):
Yes. - I use separate records that tracks everything. Build the yaml files to instantiate the network and construct network config from them when its running too. There's a surprisingly small amount of information you need to store. In this case I have a list of peers in each channel record.
tballast (Fri, 02 Aug 2019 13:15:12 GMT):
Ahh ok so you dynamically create the network-config file? I've tried to use it but found it somewhat useless when trying to stand the network up because you cant pull the information you need from it (at least not with the NetworkConfig class).
So then if you construct the network on one PC, then can you just give those files to someone else to run from another one where they would only need to read it and then jsut add those peers?
aatkddny (Fri, 02 Aug 2019 13:21:15 GMT):
yes. i do it from scratch with what i have in the records.
tballast (Fri, 02 Aug 2019 14:06:09 GMT):
When you say "separate records" what do you mean? like, what I have now is essentially just a properties file that has the peer information and stuff, then I read this in and just join all the peers belonging to the organization. I don't have a yaml file for this. Are you using your own custom code to build the network config, or is this something provided by the SDK? Sorry for all the questions, I've spent a fair bit of time on this though, and I need a better way to handle it.
aatkddny (Fri, 02 Aug 2019 14:10:37 GMT):
Its all custom. I generate the yaml files to create the network and a set of network descriptor records (orgs, users) inside a nosql database.
i track ca enrollments there also - it gives me a place to stash the certs after i encrypt them.
when i create a channel i add a channel record and track the peers that have joined in there (actually it's orgs because I join all the peers at the same time when i create the channel, but the idea is the same).
when i go to use the network these records are then used to build the network config that allows me to do a channel.loadfromnetworkconfig to interact with the thing.
does that help?
tballast (Fri, 02 Aug 2019 14:18:27 GMT):
:ok_hand: Awesome. That sounds like a pretty great setup. So in this case, if there are no records, will you assume that you need to setup the network from scratch, or will that always be a step in which the user must be aware that they're constructing from scratch?
aatkddny (Fri, 02 Aug 2019 14:27:39 GMT):
there's a rest endpoint - you pass in a config file with the orgs and a few other pieces and it builds the yaml files and a bash script to start the network. you run scp in and run that on a server and you are gtg.

Hi, Hope everyone is doing good. I am trying to install & instantiate chaincode using JAVA-SDK. It does works perfectly fine for Node and JAVA chaincode, but I am getting a strange error with GO chaincode. I am not sure if I am missing something. Would be great if anyone could help.```
`Failed to generate platform-specific docker build: Error returned from build: 1 "can't load package: package github.com/example_cc: no Go files in /chaincode/input/src/github.com/example_cc``
```
nitishbhardwaj19 (Sun, 04 Aug 2019 14:19:57 GMT):
NOTE: GO chaincode gets instantiated if I use `setChaincodeSourceLocation` option to install chaincode. But It fails if I use option `setChaincodeInputStream`

this is a cross post from the kubernetes list. has anyone got service discovery working with k8s and the java sdk?
i thought it was a security issue brought on by my move to raft, but it fails with a plain vanilla kafka (and no tls) setup too. different errors, but at the same point in time - trying to install/instantiate chaincode.

Hello guys, I am using fabric-sdk-java to query the network and find the block details. when using `channel.queryBlockchainInfo();` I get block at height 37 and when using `channel.queryBlockByNumber(current);` The current block height is 36, for both the function returned block is the same with same block hash, but block height is different. Is it by design?

Hi Guys, I am trying to instantiate chaincode using this code `channel.sendInstantiationProposal(instantiateProposalRequest, channel.getPeers());`. The code executes without error and docker container is created for the chaincode. but when I check peer's for instantiated chaincode, it is not listed on peer. I have to manually run `peer chaincode instantiate` on peer to start using the chaincode. Is there anything else I need to do to get chaincode listed on peer using the java sdk?

There is an example in [E2E](https://github.com/hyperledger/fabric-sdk-java/blob/release-1.4/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java#L483) - I believe after you get sufficient responses from `sendInstantiationProposal` you would need to then `sendTransaction()` as shown (Instantiating a chaincode is a full transaction operation)

suspect no-one has tried this, but it's worth trying before i go down the rabbit hole.
creating a channel dynamically with raft ordering using n from m of the raft-orderers I have in hand. I have it working with m from m, but the one of the plus points of raft as i understood it was that you can use a subset for efficiency.
is just adding the n orderers (and tracking them) to the channel when I create it sufficient or are there some other hoops to jump through?

The channel definition appears only to reference the original consortium - which lists all of the orderers. i'm hoping that doesn't mean i have to partition the consortiums too.
yacovm (Thu, 08 Aug 2019 21:07:59 GMT):
@aatkddny we tried it ;)
yacovm (Thu, 08 Aug 2019 21:08:56 GMT):
it is possible to create `m out of n`, or `n out of n` , but i think that creating `n out of n` and then removing them gradually is easier. To make the `m out of n` you need to pass in a special flag in the CLI
yacovm (Thu, 08 Aug 2019 21:11:14 GMT):
It is possible

@yacovm I get that. I was more interested in the mechanics.
Let me try to explain why - or what - I'm asking.
My configtx has a consortium profile that I add all my members to, before defining channels for the inter party relationships.
Let's call it "All-Members-Consortium".
In there there's a section that looks like this - ignore the number of orderers, I know I need to up it for n from m.
```
Orderer:

When I create a channel with the SDK the code I use is cribbed from an early version of the End2End... examples. The relevant piece looks like this:
```
// Just pick the first orderer in the list to create the channel.
Orderer anOrderer = orderers.iterator().next();
orderers.remove(anOrderer);
log.debug("Calling SDK to create a new channel {}", cd.getId());
Channel channel = client.newChannel(cd.getId(), anOrderer, channelConfiguration, signatures);
log.debug("Back from SDK after creating new channel {}", cd.getId());
if (orderers.size() > 0) {
for (Orderer orderer : orderers) { // Add remaining orderers if any.
channel.addOrderer(orderer);
}
log.debug("Added {} remaining orderers - {}", orderers.size(), orderers.stream().map(o -> o.getName()).collect(Collectors.joining(" ")));
```
My question is is it sufficient to discriminate here - restrict the list of orderers to n (rather than the m that's returned now) and that's all that it requires, or do I need to have different consortium profiles - one each with the correct n orderers, or is there an override at the channel level that I can expose into the genesis block for that channel?

yacovm (Fri, 09 Aug 2019 14:56:32 GMT):
you're using the SDK and I have no clue how to use it, I never did
yacovm (Fri, 09 Aug 2019 14:56:55 GMT):
in general, to create a channel with a subset of orderers you just need to change the consenters array
yacovm (Fri, 09 Aug 2019 14:56:59 GMT):
that's it... nothing more
aatkddny (Fri, 09 Aug 2019 15:09:11 GMT):
The array in configtx.yaml?
aatkddny (Fri, 09 Aug 2019 15:10:21 GMT):
@yacovm - the array defined in the profile you use that comes from configtx.yaml that's encoded into the channel genesis block?
yacovm (Fri, 09 Aug 2019 15:10:40 GMT):
yeah...
aatkddny (Fri, 09 Aug 2019 15:11:42 GMT):
Which gets me back to my question - or part of it. Is there a way to override that on a per channel basis? It seems an awful design to have to have multiple profiles to use a subset of the orderers.
yacovm (Fri, 09 Aug 2019 15:15:24 GMT):
oh... but can't you just change the file without changing the profile?
yacovm (Fri, 09 Aug 2019 15:15:40 GMT):
these stuff are really designed to be scripted and automated
yacovm (Fri, 09 Aug 2019 15:16:22 GMT):
Fabric is eggs, flour, and a bowl. You make the cake yourself, and sometimes you even have instructions how to do that

Which file? Configtx? You mean regenerate *that* profile as required? It's the same idea as having multiple profiles.
yacovm (Fri, 09 Aug 2019 15:17:35 GMT):
yeah configtx
aatkddny (Fri, 09 Aug 2019 15:17:41 GMT):
Ugh.
yacovm (Fri, 09 Aug 2019 15:17:53 GMT):
hey... it's either multiple profiles
yacovm (Fri, 09 Aug 2019 15:17:58 GMT):
or a single one you edit
yacovm (Fri, 09 Aug 2019 15:18:12 GMT):
any way you look at it - you need to script stuff and automate stuff
yacovm (Fri, 09 Aug 2019 15:18:27 GMT):
but - creating a channel should not be done too much in your life
yacovm (Fri, 09 Aug 2019 15:18:39 GMT):
if you end up creating channels on a daily basis - you're using Fabric wrong
yacovm (Fri, 09 Aug 2019 15:18:48 GMT):
unless you're building a fabric SaaS offering
aatkddny (Fri, 09 Aug 2019 15:20:46 GMT):
I generate it already. It's just a poor (imo) design to not allow a subset of the list you provide for the genesis block to be defined in the individual channel blocks for the same consortium.
I generate the channels when I generate a new network. I do that a lot more than you'd think in dev, which is why I spent such a lot of time to make it as close to zero touch as possible. This is a refinement to allow me to specify a subset of raft orderers, and I was looking to see if there's an accepted way to do that.
yacovm (Fri, 09 Aug 2019 15:21:36 GMT):
@jyellick ^
jyellick (Fri, 09 Aug 2019 15:24:22 GMT):
Are you saking to be able to have a set of orderers tied to a consortium? I'm a little late here, and skimmed the thread, so fear I'm missing the real question/point.

yacovm (Fri, 09 Aug 2019 15:25:06 GMT):
he wants to be able to specify many channels, each with different subset of orderers, without duplicating profiles
yacovm (Fri, 09 Aug 2019 15:25:13 GMT):
@aatkddny did i get you right?
aatkddny (Fri, 09 Aug 2019 15:25:35 GMT):
yes. exactly right.
yacovm (Fri, 09 Aug 2019 15:25:54 GMT):
I guess you can use the inheritance property of the YAML and use it to inherit as much information as possible
jyellick (Fri, 09 Aug 2019 15:26:40 GMT):
That would generally be my recommendation. You're generating different channel creation txes, so, you're going to need to give the tool different inputs, no way around that. But, you should be able to use basically the same profile for every one via yaml references and only change the orderers
aatkddny (Fri, 09 Aug 2019 15:26:41 GMT):
i define the consortium in a profile in configtx and list all the orderers. i ought to be able to pick a subset for this channel - or what's the point - without having to create a new consortium profile (or bogart the original)
jyellick (Fri, 09 Aug 2019 15:27:21 GMT):
I don't follow... you can pick a subset of the orderers when creating a new channel.
aatkddny (Fri, 09 Aug 2019 15:27:26 GMT):
how?
aatkddny (Fri, 09 Aug 2019 15:27:40 GMT):
that's the genesis of this. is there an override in the channel definition?
jyellick (Fri, 09 Aug 2019 15:28:13 GMT):
By default, when generating a channel creation tx, everything outside of application section is essentially ignored. This is to keep you from shooting yourself in the foot, by overriding things that are already specified in the orderer system channel. Things like your orderer addresses, block validation policy, etc.
jyellick (Fri, 09 Aug 2019 15:29:05 GMT):
However, you can use the `-baseProfile` flag when generating your channel creation tx. This will generate a channel creation tx which is _exactly_ as specified in the profile, applying any differences from the base profile.
jyellick (Fri, 09 Aug 2019 15:29:28 GMT):
This is definitely a little dangerous and error prone, so not something we typically encourage users to do. It's usually easier to generate the channel, then update it.
jyellick (Fri, 09 Aug 2019 15:30:26 GMT):
Note, to pick a subset of orderers, you'll need the consent of the ordering admin, so they'll also need to sign your channel creation tx.
jyellick (Fri, 09 Aug 2019 15:30:57 GMT):
We almost added an example of this, but decided against it https://gerrit.hyperledger.org/r/c/fabric-samples/+/30938
aatkddny (Fri, 09 Aug 2019 15:33:32 GMT):
ok so there is a way to do it. that was what i was trying to figure out.
i have to get the orderer admin to sign anything to do with the system channels, so that's the same as everything else.
What's interesting - to me at least as an aside - was that I need to get that AND all the orgs to consent to add a new member. I figured the orderer would suffice.
One final thing. Your text above implies that it's possible to remove orderers dynamically by editing the config.
Is that considered a better route than doing it as part of the channel generate with the profile?

jyellick (Fri, 09 Aug 2019 15:36:09 GMT):
You can modify consortium membership with only an orderer signature
jyellick (Fri, 09 Aug 2019 15:36:25 GMT):
But you cannot modify existing channel membership
jyellick (Fri, 09 Aug 2019 15:36:25 GMT):
But you cannot modify existing channel membership (only a majority of app org admins can do that)
aatkddny (Fri, 09 Aug 2019 15:36:38 GMT):
not by default. It throws a sub policy not satisfied.
aatkddny (Fri, 09 Aug 2019 15:36:57 GMT):
i had to add sigs from all the other org admins to do so.
jyellick (Fri, 09 Aug 2019 15:37:17 GMT):
There is something going wrong with your update then. Perhaps you are modifying the other org definitions as well?
jyellick (Fri, 09 Aug 2019 15:37:47 GMT):
The only time you should need a consortium member signature when modifying the orderer system channel is when you try to modify a consortium org member's org definition.
aatkddny (Fri, 09 Aug 2019 15:38:01 GMT):
added a new org. created and stood up the nodes. then tried to add to the consortium.
aatkddny (Fri, 09 Aug 2019 15:38:23 GMT):
required sigs from the other admins as well as the orderer admin.
jyellick (Fri, 09 Aug 2019 15:38:41 GMT):
All I can say is that, at least with the default set of policies, this is not the case.
aatkddny (Fri, 09 Aug 2019 15:39:06 GMT):
wrote the code to do this yesterday so it's still fresh. policies are from the configtx template - those i didn't change.
jyellick (Fri, 09 Aug 2019 15:39:36 GMT):
Look at the `mod_policy` value for the `/Channel/Consortiums/` group
jyellick (Fri, 09 Aug 2019 15:39:40 GMT):
What is that set to?
aatkddny (Fri, 09 Aug 2019 15:40:44 GMT):
the default. it's not overwritten.

jyellick (Fri, 09 Aug 2019 15:42:19 GMT):
This is the default, which is `/Channel/Orderer/Admins`, which says only a quorum of ordering admins should have to sign off on updates.

Adding or removing members (sub-groups) will only trigger this policy. The only way the other member policies would need to be satisfied, is if you were also modifying the definitions of those members.

```
This is boilerplate. I'm not sure how I've got it so different.
jyellick (Fri, 09 Aug 2019 15:46:43 GMT):
It's your config update that is likely the problem. Compare the versions in the read-set for your existing orgs to the versions in the write-set of those orgs. I expect you'll find they are different.
One common mistake is not re-encoding the original config through `configtxlator` if you are pulling via an SDK. Proto marshaling is non-deterministic by default so `configtxlator` takes special steps when encoding which are necessary to safely compare when computing the update.
aatkddny (Fri, 09 Aug 2019 15:47:50 GMT):
I generate the update transaction through configtxlator.
jyellick (Fri, 09 Aug 2019 15:48:46 GMT):
Yes, but the inputs, the original config, did you generate that via configtxlator's encode function?
aatkddny (Fri, 09 Aug 2019 15:49:02 GMT):
this is the same code i use for all my system channel updates.
aatkddny (Fri, 09 Aug 2019 15:49:12 GMT):
yes.
jyellick (Fri, 09 Aug 2019 15:49:47 GMT):
Then you should compare your read-set and write-set versions for those orgs.
aatkddny (Fri, 09 Aug 2019 15:50:18 GMT):
decode the block using configtxgen. edit it. pass the two to configtxgen to generate an update and do a channel update.

If they match, and you are still requiring their signatures when updating the consortium definition, then this would be a bug that's worth investigating.
aatkddny (Fri, 09 Aug 2019 15:52:28 GMT):
i'm assuming i put the new org in the right place.
```"channel_group">"groups">"Consortiums">"groups">"All-Member-Consortium">"groups"```
aatkddny (Fri, 09 Aug 2019 15:52:42 GMT):
All-Member... is my consortium here
aatkddny (Fri, 09 Aug 2019 15:53:08 GMT):
It does let me create channels with this new org, so I *think* I got it right.
jyellick (Fri, 09 Aug 2019 15:54:14 GMT):
Yes, that's the right spot to put it. But, the `mod_policy` of `All-Member-Consortium` _should_ be `/Channel/Orderer/Admins`, which means you should be able to add and remove group members satisfying only that policy.
aatkddny (Fri, 09 Aug 2019 15:54:30 GMT):
Well it doesn't work. Sorry.

jyellick (Fri, 09 Aug 2019 15:58:16 GMT):
If you could share the artifacts from your config update flow, I expect I could get to the bottom of it.

the last gets passed into the sdk as an `UpdateChannelConfiguration` which is signed by the orderer admin (and the peer admins for each of the other orgs) through a client using the orderer admin as the user. Code looks like this
```
// Sign the update configuration - orderer needs to do this. This is a special case, unlike the channels where the members sign.
UpdateChannelConfiguration updateChannelConfiguration = new UpdateChannelConfiguration(updateBytes);
byte[] osig = client.getUpdateChannelConfigurationSignature(updateChannelConfiguration, client.getUserContext());
Collection orgs = orgs();
orgs.remove(org.getName());
// byte[][] signatures = getSignatures(orgs, updateChannelConfiguration);
Set sigs = new HashSet<>();
sigs.add(osig);

You have an `Application` section in your orderer system channel
jyellick (Fri, 09 Aug 2019 17:30:48 GMT):
And, your consortium members are in it
jyellick (Fri, 09 Aug 2019 17:31:22 GMT):
It has a `mod_policy` of `Admins`, which, as a full path is `/Channel/Application/Admins`, which requires a majority of your consortium members to sign off.
jyellick (Fri, 09 Aug 2019 17:31:50 GMT):
Your config update is modifying the `ACLs` section of your `/Channel/Application` group.

jyellick (Fri, 09 Aug 2019 17:32:57 GMT):
What you have done, is you have retrieved the original configuration as protobuf (binary), decoded it to JSON, modified it, and re-encoded it as binary. Then you have passed these two binaries to configtxlator to compute your update
jyellick (Fri, 09 Aug 2019 17:33:10 GMT):
This flow looks correct, but it's actually subtly wrong.
jyellick (Fri, 09 Aug 2019 17:34:26 GMT):
You must retrieve your original configuration as protobuf, decode it to JSON, *re-encode the original JSON to protobuf with configtxlator*, modify the JSON, and re-encode the modified JSON, and send the pair of re-encoded protos to configtxlator. _Not_ the original proto and the reencoded one.
jyellick (Fri, 09 Aug 2019 17:35:20 GMT):
This is necessary, as I mentioned before, because protobuf encoding is non-determinstic (usually), and the original proto you retrieved, was not encoded with any effort for determinism. When configtxlator encodes, it uses a special scheme for deterministically encoding protos.
jyellick (Fri, 09 Aug 2019 17:36:05 GMT):
When you computed the update with your original proto, and your re-encoded proto, the order of the ACLs were changed, because of random order map iteration. To the update computation, it looked like you had changed this field. So, it was encoded into your update erroneously.
aatkddny (Fri, 09 Aug 2019 17:40:39 GMT):
I retrieved the current channel block as binary. So this is the original here.
If I understand this correctly, I need to run it through a decode/encode pair before using it as the first file.
Then the second one is the decoded, modified, re-encoded one I have.
Yuck. That wasn't in the example I cribbed from...
Also are you saying that the Application section in the profile isn't needed at all?

jyellick (Fri, 09 Aug 2019 17:45:36 GMT):
Most of the examples are derived from the CLI, by nature of not being able to drill through the proto structures ends up doing the JSON re-encoding by side-effect.
jyellick (Fri, 09 Aug 2019 17:46:01 GMT):
But yes, for a correct config update, you need to do a wash cycle of the binary input through configtxlator before trying to compute the update.
jyellick (Fri, 09 Aug 2019 17:47:55 GMT):
As far as not needing the application section in your orderer system channel, yes, you should be able to do without this. However, unless there is an application section, you will not be able to connect peers to this channel. So, if your update flow involves pulling the channel config via a peer (which, the Java SDK does by default I believe), then you do need it.
I know that the Java SDK was looking into adding another API for pulling config direct from orderers to bypass this limiation (this is what the CLI does), but I'm not sure where that stands.
aatkddny (Fri, 09 Aug 2019 17:52:20 GMT):
You pull it via a client instance that uses the orderer admin as a user.
It creates a channel object then adds in orderers and peers as required.
It used to be that you needed an extra "orderer-peer" but that limitation seems to have been removed in either 1.3 or 1.4.
I'm now able to do this with a channel with no peers attached so I guess it's been fixed.
aatkddny (Fri, 09 Aug 2019 17:55:14 GMT):
Ok, I'll remove the application section in this profile template and see what that does when I re-gen this network.
If that's good I'll try adding a selective orderer section to define a subset of orderers in the channels. Which is what started this all...
Thanks for your help here.

How significant are the changes to the Fabric SDK Java from 1.4.2 to 2.0.0? I imagine the upgraded service discovery, chaincode lifecycle, and the new chaincode deployment model are the main changes. Is that right?
sstone1 (Tue, 13 Aug 2019 08:17:21 GMT):
Same answer as for Node.js - the major changes are chaincode lifecycle. AFAIK, new chaincode deployment model (external builders) has no SDK impact. There’s also work that will continue to be done on top of the programming model enhancements delivered in 1.4.

Hi I want to add a new org to a channel and then add a peer from the new org to the network. I'm updating the channel-config and it all looks fine. Then I want to join with the peer. With this I need to provide the genisis block. In this block there is not the new org (because the org is not there from scratch). Now the new peer get's an error "MSP error: channel doesn't exist". What I'm doing wrong?

What does GenesisBlock mean to you here?
Usually you use a peer admin to get the latest block with a `Channel#getChannelConfigurationBytes()`. Then you'd update that, have the necessary peer admins sign it and do a `Channel#updateChannelConfiguration` There's a pretty easy to follow example in one of the SDK samples somewhere.
If you are talking about what used to be called the genesis (but now iirc is system) channel - because you want to add a new channel, say - then it's the same idea but you patch in the orderer admin as the user into the client. The latest SDK version seems to have been amended to not require what I called an orderer-peer (special peer with orderer crypto) any more.
Thanks to whoever did that, it's much much cleaner...

I am trying to implement service discovery, mostly following the Service discovery example in the Integration Tests, however I am not currently using TLS, and every time it tries to fetch the genesis blocks from my peers (two orgs, two peers each) it is using the grpcs protocol, and not just just grpc. I have not specified grpcs anywhere , it seems to be doing this by default. Is there a way to force it to use grpc? I am already using the `sdprops.put("org.hyperledger.fabric.sdk.discovery.default.protocol", "grpc:");` property.
Coada (Tue, 20 Aug 2019 12:08:14 GMT):
Hello! I am trying to create a Channel object to hold everything regarding a channel that has been created outside the scope of the Java application. My starting point is to call queryChannels(peer) and from the returned string(s) construct the object. However I still don't know which orderers are part of the channel, if it is initialized, etc. Perhaps this is not the way to go - how should I proceed?
bestbeforetoday (Tue, 20 Aug 2019 12:48:37 GMT):
I think if you have multiple orgs then you will need to be using TLS. As I understand it (which might not be perfectly correct!), the discovery information is passed between orgs using the gossip protocol using TLS.

tballast (Tue, 20 Aug 2019 13:35:21 GMT):
Hmm, ok gotcha. Yea, I was under the impression that it was with the gossip protocol but didn't know that it required TLS. I was able to get it to try to stop using TLS, however then I get an error along the lines of `url: grpc://peer1.org1.example.com:8051} was shutdown.`
tballast (Tue, 20 Aug 2019 16:01:33 GMT):
Is there a reason why, when communicating with a peer with TLS (querying chaincodes, for instance), the client would simply not be able to reach a specific peer?
I try to query my peers to see which chaincodes are installed, and the client is able to easily talk to the first one at `grpcs://peer0.org1.example.com:7051`, but the second peer `grpcs://peer1.org1.example.com:8051` simply isn't reached at all.
I have both of these mapped to localhost in my `/etc/hosts` file, and the only different I can see between the actual peer objects is that one has the property `"org.hyperledger.fabric.sdk.peer.organization_mspid" -> "Org1MSP"` while the other (the ont that can't be reached) doesn't. The first peer is also enabled for service discovery and the second isn't.
mattiabolzonella1 (Wed, 21 Aug 2019 07:56:41 GMT):
Hi, I've read that the API cannot query for all channels that exist but if I use several connection profiles each defining a channel, can I set the ConnectionProfile in the NetworkConfig object several time during the application execution? If so, it's a bad practice?
mahoney1 (Wed, 21 Aug 2019 10:11:29 GMT):
Depending on your use case, for queries, your applications would query using `evaluateTransaction` (example here -> https://github.com/hyperledger/fabric-gateway-java )
using the 1.4 new programming model shown (it simply picks a peer defined in the connection profile and sends the request to it, where it is evaluated) - on subject of multiple channels see here - see https://hyperledger-fabric.readthedocs.io/en/release-1.4/developapps/application.html#network-channel and in particular how an identity would connect to the gateway (and perform an evaluateTransaction)
For multiple channels see https://hyperledger-fabric.readthedocs.io/en/release-1.4/developapps/application.html#network-channel - you would have to connect to the gateway with an identity and obviously disconnect when your unit of work is done for that gateway.

Now i think that I need some sort of tool in order to genereate wallets, am I correct?
davidkel (Thu, 22 Aug 2019 09:41:00 GMT):
You need to use the wallet api to import identities into wallets as it also generates a metadata file which is what you are missing. However it is a bug in the java implementation for getAllLabels() as it should check for the existence of the metadata file by calling the exists method itself. So would suggest raising a jira for that
mattiabolzonella1 (Thu, 22 Aug 2019 09:46:27 GMT):
The wallet API that you're referring is the class Wallet.Identity? So I need to call `createIdentity()` and the put the identity returned in the wallet using `put()`. Anyway, thanks for helping me!

I'm looking at the source code of the gateway SDk, in particulare the `submitTransaction` method, I'm using the service discovery. As I can tell if the `TransactionProposal` fails (the chaincode returns a `TransactionResponse` with status 500) in the `Channel` class of the base SDK an Exception is thrown because the `DiscoveryOption` `inspectResult` is not set to `true` which is used if all `TransactionResponse` invalid and valid are required in the application for further inspection, like get the Response message.
Instead, a generic `GatewayRuntimeException` is returned with the default message `"Could not meet endorsement policy for chaincode ... `. So my question is: Can i get the invalid response message returned by the chaincode using the gateway SDK?

When instantiating (java) chaincode with the SDK it is not possible to give it a path for the ChaincodeID. When doing it manually (ie. through the CLI) you must specify it. Thus, they end up with different chaincode IDs. If i install chaincode on Org1 peers with the SDK, and Org2 peers with the CLI, how can I get the program to realize these are the same?

how can I run End2EndIT.java in Eclipse?
tballast (Wed, 28 Aug 2019 08:34:16 GMT):
not sure, I use intelliJ, but I have it set up to run as a JUnit test. If you can do something like that it should work.
lotty02cho (Wed, 28 Aug 2019 08:45:57 GMT):
I'm using eclipse, when I click End2endIT.java and click right button, there is a Run as > Junit Test. So, I click it but it said that "No JUnit tests found."
How can you start JUnit test? Thanks for replay:)
tballast (Wed, 28 Aug 2019 08:52:14 GMT):
Again, not sure for eclipse as I've never used it, but you may have to tell it exactly where you want it to look. Like, does it as for a "Main Class" or something? In intellij there are "Run Configurations" which have all of the details required for running in what ever way you want, and the JUnit tests are all "class tests" with, for example, the End2EndIT test class specified as the class to test.
lotty02cho (Wed, 28 Aug 2019 08:57:59 GMT):
Umm.. I'm already use node-sdk, so I'm very confused. and honestly I'm not good at java. so that's why I'm asking you.
*my ultimate goal is to query data and invoke my own channel.*
Let's say I already make byfn network, using fabric-samples/first-network, I try to query and invoke someone's data in mychannel.
tballast (Wed, 28 Aug 2019 09:00:58 GMT):
I see, yea that's alright. I know that getting it to run the first time can be tricky. What I would first recommend, if you haven't already, is just figure out how to get a basic application running using Eclipse. It can be a hello world or whatever, but maybe if it uses maven and imports a package that could be useful. Then, there is an example [here](https://medium.com/@lkolisko/hyperledger-fabric-sdk-java-basics-tutorial-a67b2b898410) which I've found useful for the basics of invoking and querying.
lotty02cho (Wed, 28 Aug 2019 09:09:31 GMT):

JanKosecki (Wed, 28 Aug 2019 17:03:01 GMT):
Also, I have 3 peers in the same organization for resiliency with endorsement policy requiring only one peer to approve - it works fine using `sendTransactionProposalToEndorsers` - a proposal request is made to only one of 3 peers but then what is the best approach, when the same SDK clients wants to query chaincode?
JanKosecki (Wed, 28 Aug 2019 17:03:47 GMT):
Should I simply round-robin one of the peers, check if it's available and if yes query it? Or should I query all 3 peers (but then what if 1-2 peers are down)
nmutter (Wed, 28 Aug 2019 18:26:19 GMT):
I'm running different peers and clients on multiple servers. When executing transactions after start of a client everything is ok, but after ~3-4 minutes without activity all following requests will get timeouts. Is there some hearbeat value for the clients? If I restart the client, the connection will work again for some minutes. It feels like the connection timesout, but the sdk does not notice it?
nmutter (Wed, 28 Aug 2019 18:30:54 GMT):
Maybe I need to set the properties for peers and orderers? Like https://github.com/hyperledger/fabric-sdk-java/blob/31727ee7c44aa011b5906db102d939f1371736e6/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java#L846

This is the sample code in the latest End2endIT.java. It's been pretty much the same since 1.0 as far as I can tell.
If some of your endorsers fail - for a known reason (in my case they can't get to read from another channel) - what are you *supposed* to do here?
You can't send all the ProposalResponses - the filing ones cause this to come out of Channel
`The proposal responses have 1 inconsistent groups with 2 that are invalid. Expected all to be consistent and none to be invalid.`
Send the ones that pass to the orderer and let it figure out if that's enough to pass endorsement?

Or do you need to figure out if these responses pass yourself?
My setup is a pure OR for all the orgs (single yes from any is sufficient) so without reconstituting a network that's in use it's difficult for me to test myself. Wondering if anyone knew off the top of their head.

dan13 (Tue, 03 Sep 2019 18:09:45 GMT):
This is a great question. My assumption is that the client needs to decide how to process and then make appropriate adjustments to the transaction submitted to Orderer, or fail and return error to its caller. Likewise, if query and get different responses, figure a way to a) retry (assuming can wait for network to "settle"), b) pick the response with most instances responding (voting), or c) pick the response from the peer with the greatest block height, d) something else? Would be great to have some of these impl design patterns documented by the HLF team.

I'm slightly confused as to why there are multiple TransactionActionInfos per TransactionEvent and was hoping someone here might be able to help me out!
Each TransactionActionInfo - as I understand it - corresponds to a Collection from a particular ProposalRequest. But if there can be multiple TransactionActionInfos in a TransactionEvent, does that mean you can combine multiple Collection, from different ProposalRequests, into a single transaction to be sent to the orderer? And if so, which of the TxIDs is set within the TransactionEvent?
Apologies if this is an obvious question. I did attempt to search the docs for an answer before posting here!
bestbeforetoday (Fri, 06 Sep 2019 12:37:32 GMT):

Chaincode events are attached to TransactionActionInfos. A transaction invocation may emit multiple chaincode events so there may be multiple TransactionActionInfos in a TransactionEvent

If this is like the node SDK then I may be able to shed some light. The format required looks like this:

"name": "Org1",
"policy": {
"identities": [
{
"role": {
"name": "member",
"mspId": "Org1MSP"
}
}

"policy": {
"1-of": [
{
"signed-by": 0
}
]
}
},
"requiredPeerCount": 0,
"maxPeerCount": 1,
"blockToLive": 0,
"memberOnlyRead": true
}
]
```
awjh (Thu, 12 Sep 2019 13:43:09 GMT):
There is (to my knowledger) no members only write. Fabric allows any peer to write to a private collection so long as the peer whose private collection it is approves the transaction (simplified). It will approve the transaction if the endorsement policy for the chaincode is met. Therefore the write aspect of a private collection is controlled by the chaincode's endorsement policy rather than the collection config
awjh (Thu, 12 Sep 2019 13:46:22 GMT):
This allows fabric to cut down on the number of peers having to execute the chaincode to meet the endorsement policy. Imagine an endorsement policy of `OR('Org1MSP.peer', 'Org2MSP.peer')` on a chaincode which writes to the private collections of Org1 and Org2. If the peer for Org1 returns true then there is no need for fabric to wait on the response of Org2's peer as the OR condition is already true. If private collections were member only write then since Org2 did not execute the chaincode it wouldn't have updated its private collection and therefore would be out of step with Org1. (Note: this is a simplified version of fabric's processes)
awjh (Thu, 12 Sep 2019 13:46:22 GMT):
This allows fabric to cut down on the number of peers having to execute the chaincode to meet the endorsement policy. Imagine an endorsement policy of `OR('Org1MSP.peer', 'Org2MSP.peer')` on a chaincode which writes to the private collections of Org1 and Org2. If the peer for Org1 returns true then there is no need for fabric to wait on the response of Org2's peer as the OR condition is already true.

Forgot to mention. In the example I posted above the 0 in the signed-by refers to the index of the identity in the identities that it should be signed by
Coada (Thu, 12 Sep 2019 15:47:30 GMT):
@awjh I appreciate your extensive reply. However you highlight an important point - that it only applies if it is like the node SDK, which it isn't.
The format is different (see https://github.com/hyperledger/fabric-sdk-java/blob/master/src/test/fixture/collectionProperties/testCollection.json) and there is no mention of a memberOnly property. Even if I add a memberOnlyRead property it seems to be ignored, I can query the private data as a non-member.
As for member only write, it seems to just recently have been added so I realize I probably can't set it just yet:
https://github.com/hyperledger/fabric-protos/blob/master/common/collection.proto#L61
awjh (Thu, 12 Sep 2019 15:51:39 GMT):
Okay, I unfortunately only have experience with the Node SDK :(
Cheers for the heads up on membersOnlyWrite wasn't aware of that going in, will be useful for me once implemented in the SDKs

Hi ,class Attribute in package org.hyperledger.fabric_ca.sdk is non seriallizable. Can this be made serialisable? Is there any design consideration why attributes aren't serializable? Ideally I would want to construct a user object along with attributes, serialise it and store it somewhere to access it when needed.
jdfigure (Mon, 16 Sep 2019 16:06:49 GMT):
Hi! Is there a release date planned for Java SDK version 1.4.5?
bestbeforetoday (Tue, 17 Sep 2019 15:39:27 GMT):
No target date yet that I know of. Certainly we will want 1.4.5 published by the time the a release version of _fabric-gateway-java_ is published, since it relies on some changes that went into _fabric-sdk-java_ since 1.4.4. Is there a particular fix/change that you need published?
bestbeforetoday (Tue, 17 Sep 2019 15:41:35 GMT):
You could just serialize it yourself, either using your own de/serialization scheme or using the Attribute's `toJsonObject()` method
jdfigure (Tue, 17 Sep 2019 15:53:59 GMT):
Thanks for the update - we're trying out Java Gateway and that is the reason I asked.

vijay5378 (Wed, 18 Sep 2019 08:13:04 GMT):
I did just that. I was just wondering if there was any specific reason for not being serializable.
bestbeforetoday (Wed, 18 Sep 2019 08:29:47 GMT):
The master build is not currently passing due to an issue related to the Node chaincode container. Once that's resolved and we can see verify builds pass we can start merging changes again
SteveKIM (Thu, 19 Sep 2019 04:19:54 GMT):
thanks for your message. I can wait for the problem to be solved. Will my gerrit state change automatically when the node chaincode container problem is solved?

Coada (Fri, 20 Sep 2019 07:38:09 GMT):
I ran into the same problem. The reason is that you are most likely using Alpine as a base for your Docker image - this is a great image because it is small, but the reason it is small is because most things have been removed from it. Netty-related native artifacts are needed for grpc communication. Replace `openjdk:8-jdk-alpine` to `openjdk:8` and you should be good to go :)

Basic Service Discovery question: when SD discovers a peer, and the peer requires mutual TLS, where/how does SD set the `clientCertBytes` and `clientCertKey` when communicating with the discovered peer? I'm seeing errors in our peers where it looks like SD isn't using a TLS client cert: `TLS handshake failed with error tls: client didn't provide a certificate`
yacovm (Fri, 27 Sep 2019 17:01:10 GMT):
you need to set it in the application @jdfigure
yacovm (Fri, 27 Sep 2019 17:01:22 GMT):
in the SDK configuration
jdfigure (Fri, 27 Sep 2019 18:57:46 GMT):
@yacovm `clientCertBytes` and `clientCertKey` are being set when the app connects to the anchor/discovery peer (let's call it peer-0 in this example) to do discovery. That works fine. During transaction proposal, SD will return discovered peer-1 as an endorser. The issue is peer-1 also uses mutual TLS. When `Peer.sendProposalAsync` executes and sets up `EndorserClient.getEndorserClient()` on peer-1 there is no `clientCertBytes` or `clientKeyBytes` in the Endpoint properties for peer-1. Thus, the transaction proposal fails with TLS handshake error on the peer.

With _fabric-sdk-java_ it is the responsibility of the application to manage identity credentials. _fabric-gateway-java_ has a *Wallet* that is used as a container for client credentials used to connect to Fabric

Note that I have done some refactoring of the wallet implementation for Node SDK v2.0 (_fabric-sdk-node_), and I plan to make similar changes for v2.0 of _fabric-gateway-java_. They will look very similar from an end user point of view; just the implementation is reworked

bestbeforetoday (Thu, 03 Oct 2019 13:47:39 GMT):
From a Gateway perspective, the only thing different with discovery should be setting discovery on with `GatewayBuilder.discovery(true)`. Setting up a Fabric environment that supports discovery is a little more involved but that's nothing specific to the SDK

In my network config json file, setting an integer Netty config via `peers.grpcOptions` like `"grpc.NettyChannelBuilderOption.maxInboundMessageSize": 123456` causes `java.lang.NoSuchMethodException: io.grpc.netty.NettyChannelBuilder.maxInboundMessageSize(java.lang.String)` . The `org.hyperledger.fabric.sdk.NetworkConfig#getJsonValue` is converting the integer to its string value.

have you ever added a peer to a channel? if so the process is very similar - you stick the update payload in something like this:
```
public Map addAnchorPeer(String msp, Map config, Map configJson) {
Map x = (Map) config.get("channel_group");
Map x1 = (Map) x.get("groups");
Map x2 = (Map) x1.get("Application");
Map x3 = (Map) x2.get("groups");
Map x4 = (Map) x3.get(msp);
Map x5 = (Map) x4.get("values");
Map y = (Map) configJson.get("payload");
Map y1 = (Map) y.get("data");
Map y2 = (Map) y1.get("config_update");
Map y3 = (Map) y2.get("write_set");
Map y4 = (Map) y3.get("groups");
Map y5 = (Map) y4.get("Application");
Map y6 = (Map) y5.get("groups");
Map y7 = (Map) y6.get(msp);
Map y8 = (Map) y7.get("values");
Map y9 = (Map) y8.get("AnchorPeers");
x5.put("AnchorPeers", y9);
return config;
```
and then write it back.
this code will never win an award for elegance - it was a bit of a suck it and see that i never got round to cleaning up, but you should get the idea.

Here is the Jira I have raised: https://jira.hyperledger.org/browse/FGJ-57
Feel free to comment if I've missed any information. I can't say how soon this is likely to get to the top of my todo list
aatkddny (Fri, 11 Oct 2019 01:21:31 GMT):
The intent with the gateway seems to be to make it a per user connection - which means having a lot more of them cached than the HFClient approach (where it's thread safe and you can swap users as soon as you submit the Tx). Is the Contract you get from the gateway still thread safe or do you need to do a gateway#getnetwork#get contract every time you want to run a Tx in a multithreaded environment? We have some system users that could potentially be running Txs concurrently.
Also a suggestion for the Builder. I have a bunch of user ids that already implement User.
I could extract the msp and the cert and pk from their Enrollment, so having a builder#identity method allowing me to pass them in would be quite nice. Or better - support passing in a User directly. so I don't have to roll my own Wallet (all our ids are encrypted and stored in a DB - our security team would have conniptions if I said we were storing user identities on the filesystem).

It is possible to create an identity from an Enrollment if that's what you mean, like so : Identity identity = Wallet.Identity.createIdentity("Org1MSP", enrollment.getCert(), enrollment.getKey());
aatkddny (Fri, 11 Oct 2019 12:13:38 GMT):
That's fairly obvious.
But unless you want to stick the then created identities into a wallet on your file system (or in memory) you still need to have a way to pass them into Gateway#Builder#Identity - all the methods there seem to require a wallet.
In this case accepting the User as an alternative would - imnsho - help with integrating identities that have followed the User pattern. Or if the desire is to pretend none of that ever happened, just accepting an Identity without requiring the wallet, requiring that the implementing code build it would perform the same function. Either works.
It's not a ton of code to write something that'll act as a wallet against a DB of User objects, but then you (one) are at the mercy of keeping up with whatever the next shiny thing is.

@aatkddny The design is that a gateway represents a single users connection. It might be possible for us optimise the internals so low-level resources are shared between Gateway instances but this does not happen today and is not something I expect to happen near-term.
bestbeforetoday (Fri, 11 Oct 2019 13:20:39 GMT):
You should be able to safely call `create/submit/evaluateTransaction()` concurrently so no need to keep calling `Gateway.getNetwork().getContract()`
bestbeforetoday (Fri, 11 Oct 2019 13:22:26 GMT):
I am planning on refactoring the wallet implementation for 2.0 in-line with the refactoring I've already done in _master_ branch of the Node SDK. Right now the objective is just equivalence with the way wallets and identities are used today. So your options would be to use an in-memory wallet and populate the content with externally stored identity information, or to write a `WalletStore` implementation that acts as an adapter to wherever your identity information is held. The refactor of wallets makes this much easier and more robust that before but does mean you have to deal with the identity persistent format, which might not be ideal for you
bestbeforetoday (Fri, 11 Oct 2019 13:23:46 GMT):
Being able to just supply an identity yourself without using a wallet sounds like a reasonable feature request. Could you raise a _Story_ to capture this in Jira? https://jira.hyperledger.org/projects/FGJ
aatkddny (Fri, 11 Oct 2019 13:27:25 GMT):
It appears - since I was trying it this am and have trace enabled - that the gateway is just a wrapper around the NetworkConfig/HFClient stuff I'm using anyway rather than something completely new. Until I have time to figure out where the ClassCast error I'm getting is coming from with the config I generate (somewhere in the certs) I'll leave it alone.
I already wrote an implementation that does pretty what you said above to wrap my user service with an in memory wallet. It's not exactly rocket science, but the maintenance when something else new and shiny comes along is my concern.
I'll add a jira. Thx.
aatkddny (Fri, 11 Oct 2019 13:41:30 GMT):
Also ``The design is that a gateway represents a single users connection. It might be possible for us optimise the internals so low-level resources are shared between Gateway instances but this does not happen today and is not something I expect to happen near-term.``
I'm talking about a single user identity - created for system processes - that may be running concurrently in multiple threads. So in this case (probably) the Network instance needs to be able to support multithreading, unless it creates a new HFClient under the covers for every Contract (which won't scale well).
The HFClient (sort of) will multithread in that once you send the Tx, you can reuse it so you don't need to serialize for very long. Something that properly serializes this access internally would be helpful here.

```* There's an issue with the way client certificates are passed. The JSON Object writers won't allow you to put a byte[] in as a value. This means the client certificate bytes need to be translated from the string representations and injected into the properties objects before you can use them.

Can you clarify the multithreading issue(s) with fabric-sdk-java HFClient? Under what conditions or how used you see threads conflicting?
aatkddny (Fri, 11 Oct 2019 18:41:54 GMT):
This might be a bit involved. I'll try not to make it too tl;dr
Consider a single-threaded application where you have a single HFClient - hfc - and two Users - U1 and U2
You are already connected to the channel.
To run a Tx you can stick U1 in hfc and off you go.
You can then stick U2 in hfc and the same applies. You are free to run a Tx.
Now same actors but multithreaded.
U1 in thread1, U2 in thread2.
If they are concurrent you can collide - swapping U2 for U1 while U1 is halfway through a Tx isn't going to do what you think it should do.
So you would think you'd serialize the client for the entire Tx.
Well not exactly. It turns out that you don't need to do it for the entire Tx. Just up until it ships it off. You DO need to serialize under these conditions though to avoid collisions. I'd need to dig back into the code - or the find the conversation with Rick on here about this some time ago - to find the exact spot. It's around one of the GRPC proto calls.
So drifting back to my question here which is only tangentially related.
I have a gateway for U1. Which gets a network. Which gets a contract.
If am running multithreaded and U1 could in theory run transactions in more than one thread at the same time, what's the serialization strategy for reuse? Do I need to get a network in each thread, or a contract in each thread or can it be synchronized in the gateway code itself?

Thank you -- that was very cogently and concisely stated. I *hope* the answer to your last question is Contract (at worst). With respect to hfc, in my current situation I maintain an hfc instance per user (these are system-type users and only a few, all connected at service startup), so I'm never setting/switching the user. Seems like I avoided the multithread-user-switch issue, unless there are other problems with reusing hfc without user switch? I'll search for your previous conversation here! Thanks!

In my application I set the User on the TransactionProposalRequest itself, not switching the HFC User. Does this also avoidthe multithread issue?
HofmT (Mon, 14 Oct 2019 15:20:28 GMT):
Hi community,
I'm also facing an issue when instantiating java chaincode through the fabric java SDK. I'm able to install the chaincode but I keep failing at instantiating it via the java SDK. When sending the installProposalRequest it always returns "Undefined contract method called". I have definitely no typo in the name. On top of that, I'm even able to instantiate it via the 'peer chaincode instantiate' command. It's just the SDK that is causing troubles.
I thought it might be related to the fact that I'm using the annotation chaincode style which you can also find in the FabCar sample chaincode here: https://github.com/hyperledger/fabric-samples/tree/release-1.4/fabcar/java
Other than that I'm using container version 1.4.3 and SDK version release 1.4
I appreciate your help. Please let me know if you need any further information. Thanks!

You can use a single Contract instance to send multiple transactions concurrently. It is thread-safe. A new client is not created every time
bestbeforetoday (Tue, 15 Oct 2019 08:33:02 GMT):
I replied in another thread but... you can use a single Contract instance to invoke multiple transactions concurrently. The concurrency issue you might face is at the blockchain level if multiple in-flight transactions have overlapping read/write sets (i.e. they manipulate the same data keys). This will result in a failure but is nothing to do with the thread safety of the client API

Has anyone got the Contract#addContractListener() stuff to work in a real environment?
I'm having a problem where my contract listener isn't getting invoked - no matter which of the flavors I use.
Even something as simple as the ripped off `stubContractListener` from the test examples never seems to get called.
My GatewayImpl is cached - so I can see it just fine.
I can follow the flow through to `Listeners.transactionFromContract(Consumer listener)` and I can see my stubbed consumer in the transaction event, but it's just never getting back to the accept method therein. My visibility inside eclipse is - shall we say - limited when it comes to lambdas.
I've wasted a couple of hours on this now and its driving me nuts, which is why I'm asking if anyone has this working. At least then I'll be sure its something I messed up...
bestbeforetoday (Tue, 15 Oct 2019 13:34:02 GMT):
The scenario tests exercise the contract listeners in a real Fabric environment, and I've used it myself for demo purposes too, so it does work. The one thing to check is that you have peers marked with the _eventSource_ role as it's only those peers that the (low-level) SDK will connect to for receiving events.
aatkddny (Tue, 15 Oct 2019 13:40:48 GMT):
I can see the peers throwing block events.
`Sending block event 'Channel everything-channel eventqueue got block event with block number: 32 for channel: everything-channel, from Peer{`
As I said I can trace the thing into the Listeners class where it ends up in here:
`Consumer transactionFromContract(Consumer listener)`
and falls through to the `.forEach` in there. There has to be something strange with my Consumer. I'll look at it some more. Thx for the response.
bestbeforetoday (Tue, 15 Oct 2019 13:46:17 GMT):
In case it helps, from my demo code:
``` // Listen for block events.
network.addBlockListener(this::acceptBlockEvent);
// Listen for contract events.
contract.addContractListener(this::acceptContractEvent);
```
``` private void acceptBlockEvent(BlockEvent event) {
long blockNumber = event.getBlockNumber();
System.out.println("Received block number " + blockNumber);
}
private void acceptContractEvent(ContractEvent event) {
String message = String.format("Received contract event named %s with %s",
event.getName(),
getPayloadString(event.getPayload()));
System.out.println(message);
}
private String getPayloadString(Optional payload) {
return payload.map(bytes -> "payload: " + new String(bytes, StandardCharsets.UTF_8))
.orElse("no payload");
}

One side note... if you are creating a new checkpoint file every time and not re-connecting to the file used previously, the checkpointing is really doing nothing for you so you should just add a block listener without checkpointer

If the peer is committing blocks but you are not receiving block events at your client, check the peer has the _eventSource_ role. You could try something like:
```network.getChannel().getPeers(EnumSet.of(Peer.PeerRole.EVENT_SOURCE))
```

That is exactly what checkpointing is designed to do. You just need to make sure a given listener is using the same checkpointer. So if you are using a file to store checkpoint information (file checkpointer), your listener needs to connect to the same file every time it is started up. Something like:
```Checkpointer checkpointer = DefaultCheckpointers.file(Paths.get("contractcheckpoint.json");
contract.addContractListener(checkpointer, this::acceptContractEvent);
```

contract.addContractListener(checkpointer, this::acceptContractEvent);
```
bestbeforetoday (Tue, 15 Oct 2019 15:07:41 GMT):
The very first time that listener is added, the checkpoint file will not exist and so the listener will start listening from the current point in time
bestbeforetoday (Tue, 15 Oct 2019 15:08:04 GMT):
As soon as any block events are received, they will be recorded in the checkpoint file
bestbeforetoday (Tue, 15 Oct 2019 15:08:33 GMT):
If you take your client off-line and restart it again later, re-attaching to the same checkpoint file, the listener will start receiving events from where it left off
aatkddny (Tue, 15 Oct 2019 15:08:37 GMT):
Then wouldn't I expect to get all the blocks for this listener if the checkpointer is new. Because right now I'm not getting anything until I do an update.
I understand I need the same one - and I have a different thing than a file in mind for it. As I said this was a test.
aatkddny (Tue, 15 Oct 2019 15:08:37 GMT):

bestbeforetoday (Tue, 15 Oct 2019 15:10:24 GMT):
If you just want to play from block 0 then you could attach a listener as `contract.addContractListener(0, this::acceptContractEvent)`
aatkddny (Tue, 15 Oct 2019 15:12:35 GMT):
I don't. I want to have a real ongoing checkpointed set of blocks for trailing aggregations.
But when I attach a listener - any listener - to a channel I want it to start from 0 if this is a new checkpointer.
So it streams everything from 0->current once and once only to allow me to recreate and maintain the state at any point for any purpose.

You should be able to do that with something like this:
``` Checkpointer checkpointer = DefaultCheckpointers.file(Paths.get("contractcheckpoint.json");
if (checkpointer.getBlockNumber() == Checkpointer.UNSET_BLOCK_NUMBER) {
checkpointer.setBlockNumber(0);
}
contract.addContractListener(checkpointer, this::acceptContractEvent);
```

aatkddny (Tue, 15 Oct 2019 15:15:26 GMT):

bestbeforetoday (Tue, 15 Oct 2019 15:18:29 GMT):
You got it, the `UNSET_BLOCK_NUMBER` means this checkpointer has not yet seen any blocks. And the behaviour for checkpoint listening when no previous blocks have been seen is to start at the current block

Yeah - we see that fairly often in eventing - if the event dispatches another Tx that read assets in the original Tx.
Function of the design, but it's a shame - or at least our devs think it's a shame - you can't flag that you don't care about reads in the RW TxSet somehow. :D

It was previously stated here that "the high level [gateway] is built on top of the low level. so you can use the low level SDK to call a high level smart contract (assuming you know what args to pass in), and the high level [gateway] SDK to call a low level smart contract (Invoke will just get called)". I have no personally tested this yet.

bestbeforetoday (Fri, 18 Oct 2019 12:06:56 GMT):
The integration tests for _fabric-gateway-java_ use both a Contract-based and a plain chaincode implementation to test against. You get hold of a plain chaincode by calling `network.getContract(chaincodeId)`. If you only have a single (default) smart contract in a chaincode container then you do the same to interact with a Contract. If you have multiple (namespaced) smart contracts in a chaincode container then you get hold of them using `network.getContract(chaincodeId, contractName)`. Other than that you use them identically from the client side.
gunso (Sat, 19 Oct 2019 12:49:26 GMT):
So, the test is done. Got it. Thanks!

bestbeforetoday (Wed, 23 Oct 2019 12:56:09 GMT):
My guess would be that there is a networking issue with your docker containers. You could check whether your client container is on the same Docker virtual network as the peer and, if so, whether that is the correct IP address and port for the peer on the virtual network. If they are not connected to the same virtual network then check that all the correct port forwarding is in place to allow connections between your client container and the peer container via your host machines network layer. A simple approach to troubleshoot might be to connect to a shell terminal within the container and use the command-line to check network routing and connectivity

This may be out of scope, and I think I already know the answer but figured I'd ask if anyone else had tried it yet.
If we switch to the Gateway/Network/Contract pattern, can the constructs be serialized so they can be shared across sessions in multiple containers.
I suspect the answer is no.
And if that is the case, is there a recommended approach for scaling out - sticky sessions, multiple local copies inside each container, something else?
I was going to go the multiple local copy route unless there's a good reason not to.

bestbeforetoday (Fri, 25 Oct 2019 15:20:35 GMT):
For some reason RocketChat isn't letting me reply to your thread right now so here goes... Any instantiate proposal sent by the Java SDK will include `init` as a function name to invoke during instantiate. My guess is that your contract implementation doesn't have an `init()` function and so the instantiate is failing. You could try implementing a no-op `init()` function in your contract to see if this allows you to instantiate using the Java SDK. If this does help, please let me know and perhaps we can make some changes to help this situation

I've replied on Stack Overflow but to save people linking off there...

Hi, i want to connect my application, which use the java SDK with a connection profile and discovery service, to a remote fabric blockchain. I was wondering if i need a DNS or mapping the logical address (peer.org1.example.com) to the ip of the machine hosting the peer.. My application needs to run outside a docker container, and with this restriction also the discovery service is affected, right? This because i have no map every new address of peers and orderers which may be added to a channel
bestbeforetoday (Wed, 30 Oct 2019 10:12:10 GMT):
The peer URLs are the physical addresses so they need to be resolvable in DNS by the client. You are correct that when using discovery, the address configured in the peer will be supplied to client during network discovery and so also needs to be resolvable in DNS at the client
bestbeforetoday (Wed, 30 Oct 2019 10:13:12 GMT):
For testing purposes you could add entries to the client's local hosts file

thanks @bestbeforetoday !
> You have the option of adding a channel definition to the connection profile
I believe I do =) But I have no idea where. Is this the (java-sdk) app part or the fabric network part?
ikar (Wed, 30 Oct 2019 10:55:12 GMT):
currently trying to modify `cpp-template.yaml` inside `first-network` dir of the fabric network. is this the correct path at least?
Bolzo 1 (Wed, 30 Oct 2019 11:03:01 GMT):
I understand, thanks for the reply

Okay, this was it! The error is gone and the performance is the same. Thanks again!

Anyone use service discovery with the latest connection profile setup and know how to turn it on off the top of their head?
I thought it was as simple as setting `"serviceDiscovery":true` in the set of json values in `channels>channel>peers>peer` but it seems to not be accepting that any more.
Of the two different profile examples I have, one doesn't use the channels json at all and the other doesn't use SD so I'm not sure what changed. The peer role isn't getting set on any of the peers and it's throwing this `throw new ServiceDiscoveryException("The channel is not configured with any peers with the 'discover' role");`
The peer *is* set to turn on SD (`discovery.enabled:true`).
If anyone remembers off the top of their head it'll save me a bundle of time with the debugger.

aatkddny (Wed, 30 Oct 2019 13:04:02 GMT):
Responding to my own post - poor form, but hopefully it'll save someone else the same.
The role name has been remapped from `serviceDiscovery` to `discover` inside the `NetworkConfig` class at `roleNameRemapHash`. Not sure why.
bestbeforetoday (Wed, 30 Oct 2019 15:15:07 GMT):
I'm not sure why that remapping was done either, but it does seem to be consistent with the Node SDK behaviour at least.
If you have a `channels` section in your connection profile then to use discovery you will need to have at least one peer in there with the `discover` role. If you omit the `channels` section (using the Gateway API) then it will be assumed that all peers have all roles so discovery should work if enabled when connecting the Gateway
aatkddny (Wed, 30 Oct 2019 15:17:38 GMT):
we have channels in the network config. it's converting from a fully expressed network.
i do have peers set for discovery - rememberer you need the core.yaml switches set too or it isn't happy.
problem now is the external orderer address thing i posted about in the orderer chat group. i'll look at reconfiguring that and rebuilding my network after lunch.

bestbeforetoday (Wed, 30 Oct 2019 15:19:47 GMT):
We were thinking of removing the notion of roles for peers in 2.0 since this is really just a client-side concept and any peers obtained through discovery just get all the roles so is less useful in the discovery scenario. It seems to cause more problems that it solves

bestbeforetoday (Wed, 30 Oct 2019 19:42:29 GMT):
No, that sounds like a bug, although it _might_ be down to the client not being able to reliably distinguish between a discovered peer and one defined in the connection profile. It would be worth raising a Jira with an example of the peer entry from the connection profile and the duplicate added with discovery
aatkddny (Wed, 30 Oct 2019 19:59:57 GMT):
I'll do it tomorrow. Need to figure out what else is missing first.
It's also interesting that the names also are required to exactly match the ones generated by SD - including the port - rather than it working off something a little less ephemeral (url I'm looking at you here).

what switches? discovery is turned on by default in the peers...

because when i was trying to build myself a raft in kubernetes setup that works with the java sdk i was having terrible terrible trouble with certificates. i got past that and then service discovery was failing - and still is when i go to submit a transaction using the gateway. my network was built from my configuration and i have some code that dynamically builds it. so i didn't need it. still really don't for my setup.
my problem came to a head when trying to connect to another vendor's network, one that has now changed all their configuration so it only uses service discovery. i need to be able to switch between our setup (non production) and the self same vendor setup (production) and don't want to support two code bases.
so now i' m back looking at what i overlooked while i was shoehorning raft in, so i can go natively with the gateway and sd for everything. i'm working through figuring out what's different between sd and a self-built config (using the 1.0 style configuration) and trying to see where everything gets set.

Hence my question about the config yaml and the orderers.

Hi @rickr @bestbeforetoday Thanks for sharing thoughts on HSM integration. I am just curious to know to know more about it. I assume that things would work as expected with HSM if we create a custom cryptoSuite which can connect to HSM. But, I found that we are referring to User's enrollment down the stream when we have to sign a transaction. ```
IdentityFactory.getSigningIdentity(cryptoPrimitives, user);
``` If that's the case, I am still not clear how we can plugin HSM support. Is there a way to play around with it? I know that's it's not supported fully, but it would be great if you can point to some pointers for just an idea of the concept.

I'm inside kubernetes - apart from my client, which isn't. So I need the external names for the orderers (localhost:nodeport). I'm getting the internal ones (raft{N}-orderer:7050). I've tried - and am trying - changing my configtx generation code to put in the external name, but it seems that every time I try to change one of the Address blocks to the external address the rafts then fail to talk to one another.
I was sidetracked by the need to go to 1.4.3, so need to go try setting these more thoroughly and checking the errors better. It was late last night when I was doing this.

What errors are you getting? I wonder if you are seeing the issue that the Java SDK always sends `init` as an initialization function name when instantiating chaincode and, if you have multiple smart contracts within one chaincode, you may not have an `init` function defined for a default (non-namespaced) smart contract. If so, you could try implementing a dummy `init` function in a default (non-namespaced) smart contract

aatkddny (Mon, 04 Nov 2019 14:50:37 GMT):
where is your network running? on a local machine or a server in your data center? the ports don't look like nodeport mappings so i'm guessing it's not kubernetes. and are you using service discovery?

HIi, there are somewhere some examples on how send multiple transaction in parallel?
aatkddny (Tue, 05 Nov 2019 12:34:04 GMT):
Using the java client? Or the fabric-gateway?
Former - Setting up multiple HFClients will do it (if you want simple but possibly marginally less efficient).
Latter - I'm not 100% convinced Contract is thread safe - since the HFClient is in the Gateway - so I'd go multiple Gateways. Caveat - I didn't write it and I haven't stepped through it, so it may well be completely thread safe and I'm just being over-cautious.
Or you could self-synchronize, but I'm betting you don't want to do that.
Bolzo 1 (Tue, 05 Nov 2019 13:03:26 GMT):
I'm using java-sdk not the gateway, my goal is to send multiple transaction proposal to multiple endorsers and collect their response
bestbeforetoday (Tue, 05 Nov 2019 13:03:53 GMT):
You _should_ be able to submit multiple transactions in parallel using a single Contract instance using a multi-threaded client and the _fabric-gateway-java_ API. I have certainly done this but personally only with simple scenarios, like driving client load on a specific smart contract transaction. If anything doesn't work correctly invoking multiple transactions in parallel then please do raise a bug with as much information as you can gather to help identify the issue
aatkddny (Tue, 05 Nov 2019 13:07:14 GMT):
So look at the code in the sample to submit a tx and stick it in a thread so you can do it multiple times.
Bolzo 1 (Tue, 05 Nov 2019 13:09:38 GMT):
My approach at the moment consists in a executor service which submits multiple callables. The callable calls the sdk to send a transaction proposal. I was wondering if my approach can be improved
aatkddny (Tue, 05 Nov 2019 13:10:56 GMT):
tp to each endorser separately then you collect? or multiple discrete transactions?
Bolzo 1 (Tue, 05 Nov 2019 13:11:37 GMT):
multiple discrete transaction
aatkddny (Tue, 05 Nov 2019 13:12:27 GMT):
you have an pool of cached hfclients?
aatkddny (Tue, 05 Nov 2019 13:12:49 GMT):
one per thread in the executor service?
Bolzo 1 (Tue, 05 Nov 2019 13:13:03 GMT):
No, i have a single HFclient and i set the user context at evety call
aatkddny (Tue, 05 Nov 2019 13:13:13 GMT):
then you aren't thread safe.
Bolzo 1 (Tue, 05 Nov 2019 13:13:37 GMT):
Oh, so i must have multiple HFClients?
aatkddny (Tue, 05 Nov 2019 13:13:50 GMT):
unless it's been rewritten since we did this, yes.
aatkddny (Tue, 05 Nov 2019 13:14:34 GMT):
you can swap in another user after you dispatch the tx, but there's a window when you can collide. So a pool is simpler and safer.
Bolzo 1 (Tue, 05 Nov 2019 13:15:13 GMT):
Can you point me to some example code?
aatkddny (Tue, 05 Nov 2019 13:15:22 GMT):
if you want really shitty performance you could inline them and get an hfclient and connect every time, but that'll get old fast.
Bolzo 1 (Tue, 05 Nov 2019 13:16:40 GMT):
At the moment it takes 1 minute and a half to do 250 tx
Bolzo 1 (Tue, 05 Nov 2019 13:17:04 GMT):
So yes I need to improve the performance
aatkddny (Tue, 05 Nov 2019 13:17:36 GMT):
you can also saturate netty - in our case it was at about 25tx/s on 200 or so threads - so be warned about that too.
Bolzo 1 (Tue, 05 Nov 2019 13:20:44 GMT):
So the idea is to have a separate HFClient per thread (or per call), am I right?

at org.hyperledger.fabric.sdk.Channel.sendTransactionProposalToEndorsers(Channel.java:3879)
aatkddny (Fri, 08 Nov 2019 14:02:02 GMT):
@bestbeforetoday Was the swallowing of error responses from chaincode when validation fails using SD intentional?
Instead of our error responses now all we get is a `ServiceDiscoveryException("Could not meet endorsement policy for chaincode XXX")`
We found that in Channel.java
```
public Collection sendTransactionProposalToEndorsers(TransactionProposalRequest transactionProposalRequest, DiscoveryOptions discoveryOptions) throws ProposalException, InvalidArgumentException, ServiceDiscoveryException {
….
….
final boolean inspectResults = discoveryOptions.inspectResults; //force this to true and the behaviour reverts to what we need
```
Unfortunately we seem to have no control over the discoveryOptions. It’s created inside `TransactionImpl` and immediately passed to the channel method:
```
private Collection sendTransactionProposal(TransactionProposalRequest request) throws InvalidArgumentException, ServiceDiscoveryException, ProposalException {
if (this.endorsingPeers != null) {
return this.channel.sendTransactionProposal(request, this.endorsingPeers);
} else if (this.network.getGateway().isDiscoveryEnabled()) {
DiscoveryOptions discoveryOptions = DiscoveryOptions.createDiscoveryOptions().setEndorsementSelector(EndorsementSelector.ENDORSEMENT_SELECTION_RANDOM).setForceDiscovery(true);
return this.channel.sendTransactionProposalToEndorsers(request, discoveryOptions);
} else {
return this.channel.sendTransactionProposal(request);
}
}
```
So - was this intentional? It's a change in behavior from what happens when SD isn't on, and it means we can't react to the errors and handle appropriately.

You want to lock an HFClient to each thread for the duration of the transaction via pool, or, if you have a limited set of users you could create instances for each, store them, and re-use the appropriate one across threads.
aatkddny (Sun, 10 Nov 2019 18:59:31 GMT):
He's already using an executor service. Unless he has a HFClient per thread in that service (or a bigger pool - which is wasteful) he's likely to bottleneck on them.
Bolzo 1 (Mon, 11 Nov 2019 15:49:06 GMT):
Yeah I have a HFClient per thread.. Each HFClient has the same information. The idea is that i want to split a series of transactions sent by a user into parallel transactions using multithreading.

bestbeforetoday (Thu, 14 Nov 2019 10:14:01 GMT):
If you are storing your credentials in a database then probably the best approach is for your client application at startup to pull the required credentials from the database and stick them in an in-memory wallet. The file system wallet is useful just if you want a simple out-of-the box storage mechanism for your credentials.

I've just check... I completely missed the try-with-resources! Now all makes sense, thanks!
bestbeforetoday (Tue, 19 Nov 2019 15:05:30 GMT):
I guess that your client will be waiting until successful transaction commit events are received from peers. This is often what you want so that any subsequent transactions or queries are seeing the world state after your transaction have been applied. But for you to see the commit events the transaction must have been included in a block that is committed on the peers, which can take a little time. Under light load the round-trip time may look artificially slow as the orderer waits for more transactions for a short period of time before committing the block (likely including only your one transaction). As concurrent load increases you will start to see multiple transactions included in each block and so the average round-trip time effectively decreases as blocks are either filling up before the wait time, or your transactions are being ordered part-way through the wait time triggered by preceding transactions.
bestbeforetoday (Tue, 19 Nov 2019 15:07:09 GMT):
Alternatively... if you don't need to wait for the world state to include state changes resulting from your transaction -- perhaps you are just firing in a batch of transaction invocations that don't rely on each others' state changes -- you can not wait for the transaction commit events and see higher throughput

Hi, When I deal with fabric-sdk-java , when testing End2endIT.java file, the channel creation is not working.
Channel newChannel = client.newChannel(name, anOrderer, channelConfiguration, client.getChannelConfigurationSignature(channelConfiguration, peerAdmin));
The above function call wait for a long time. Please help

Hi @bestbeforetoday , when using channel.sendTransaction(prResponses).whenCompleteAsync((event, throwable)-> {...}); I am not getting the event back and therefore not able to understand whether the transaction is getting committed or not. Please suggest how to confirm that.
Bolzo 1 (Wed, 20 Nov 2019 15:34:32 GMT):
I want to improve the performance of my module which use the java-sdk (not gateway). Currently the function `sendTransactionProposalToEndorsers` takes about 300 ms (`forceDiscovery` and `inspectResult` set to `true` and `endorsementSelector set to ENDORMENT_SELECTION_RANDOM`). What are the factors that affect this function? What are the best practices to use in order to optimize the performance?
bestbeforetoday (Wed, 20 Nov 2019 15:51:55 GMT):
From memory there is some default waiting behaviour that means the Future won't complete until commit events have been received. To tailor this behaviour you might want to use `sendTransaction(Collection proposalResponses, Channel.TransactionOptions transactionOptions)` instead: https://sdkjavadocs.github.io/org/hyperledger/fabric/sdk/Channel.html#sendTransaction-java.util.Collection-org.hyperledger.fabric.sdk.Channel.TransactionOptions-
bestbeforetoday (Wed, 20 Nov 2019 15:52:47 GMT):
Or use the higher level _fabric-gateway-java_ API where you can select from a few different default commit handling strategies or roll your own

_fabric-sdk-java_ is a low level API while _fabric-gateway-java_ is a higher level (read: more usable) API that is built on top of _fabric-sdk-java_. The 1.4.x release of _fabric-gateway-java_ is stable, and my recommendation would be to use that wherever practical, only using the low level API for specific tasks that are not available in the high level API

Hi @bestbeforetoday I was just going through balance-transfer sample which is implemented using node-sdk. I noticed that for each operations, transaction invoke etc, they close the channel. I am not sure whether this is required in java-sdk for resource cleanup. Would be great if you can share your thoughts.

Is there any sdk to replace configtxgen configtxlator and docker operation?will be glad if sample code is shared? #fabric-sdk-java #fabric-sdk-java
bestbeforetoday (Mon, 25 Nov 2019 11:24:30 GMT):
Connecting to the channel and then closing the connection again for every transaction invocation will result in very poor performance. Ideally you want to be staying connected while you perform a series of transaction invocations and just close connections when your client application completes.

If a transaction has been endorsed correctly, the peer will attempt to apply it to the ledger. To do this, a peer must perform a ledger consistency check to verify that the current state of the ledger is compatible with the state of the ledger when the proposed update was generated.

Purbaja (Wed, 04 Dec 2019 08:13:01 GMT):
@bestbeforetoday thanks for sharing this. But as u said, with the fabric-sdk option I am receiving every event twice. Any way to avoid this?
bestbeforetoday (Wed, 04 Dec 2019 09:39:16 GMT):
Two obvious options spring to mind:
1. Write your own code to ignore duplicate events.
2. Use the high level _fabric-gateway-java_ API, which includes this deduplication logic so you don't have to write it yourself.
bestbeforetoday (Wed, 04 Dec 2019 09:43:16 GMT):
The reason you get duplicate (and out of order) events is because the event listener listens to all eventing peers on the channel. A different approach -- although I'm not sure I would recommend it -- could be to create a new Channel object based on the "real" Channel object, and populate it with only a single eventing peer object. Listeners attached to this new Channel object will only be receiving one copy of each event because it only has one eventing peer. The downside is that, if that one peer disconnects for any reason, you aren't getting any events.

Hi Ranjan.. The port number 5051 could be wrong. For my case i have misconfigured the port number.. Can you check once?
sandy (Wed, 04 Dec 2019 11:28:58 GMT):
If the configured port number is right then just check the peer logs.

Hi, anybody has an example of code to subscribe to events for the transaction that the client has just submitted? I mean... I want my client to do a putState() and be able to wait until that transaction is finished and distributed, but only to that transaction (not other transactions that may occur in at the same time).
bestbeforetoday (Thu, 05 Dec 2019 15:06:40 GMT):
Using the _fabric-gateway-java_ API, you get this behaviour (by default for your organization peers) out-of-the-box. You can select from several alternative commit handling strategies, or write your own implementation if the defaults do not suit you:
- https://fabric-gateway-java.github.io/org/hyperledger/fabric/gateway/Gateway.Builder.html#commitHandler-org.hyperledger.fabric.gateway.spi.CommitHandlerFactory-
If you do need custom behaviour, there is a sample implementation in the "See Also" links on this page:
- https://fabric-gateway-java.github.io/org/hyperledger/fabric/gateway/spi/CommitHandler.html
As mentioned on that page, you can easily listen for transaction commit events from specific peers using `Network.addCommitListener()`:
- https://fabric-gateway-java.github.io/org/hyperledger/fabric/gateway/Network.html#addCommitListener-org.hyperledger.fabric.gateway.spi.CommitListener-java.util.Collection-java.lang.String-
icordoba (Thu, 05 Dec 2019 15:24:44 GMT):
Thanks @bestbeforetoday Do I need to add any SetEvent() method in chaincode right after the putState() or it is not needed? (Just putState will do?)
bestbeforetoday (Thu, 05 Dec 2019 15:29:44 GMT):
SetEvent() is just for emitting chaincode (which the client API calls Contract) events, which you might use to send out additional information related to a transaction only when it is committed. The transaction commit events happen automatically when each peers commits the transaction. You don't have to write any code for this to happen
icordoba (Thu, 05 Dec 2019 15:39:56 GMT):
Great. Thanks @bestbeforetoday . If you can link here to some example of using addCommitListener() method in the client code that will help a lot. (I don't know how to get the Network or Gateway objects. I just have FabricClient and ChannelClient objects in my code, no Network or Gateway)
bestbeforetoday (Thu, 05 Dec 2019 15:43:45 GMT):
Are you sure you're using the Java SDK? Those object types don't look familiar to me. There is a usage example of the _fabric-gateway-java_ API in the overview page for the API documentation:
- https://fabric-gateway-java.github.io/
bestbeforetoday (Thu, 05 Dec 2019 15:44:16 GMT):
You probably won't need to add your own commit listeners as there are several default commit handling options available
icordoba (Thu, 05 Dec 2019 15:45:43 GMT):
I'm sorry, I pasted my own library classes (coded months ago). I'll check them to figure out. Again, thanks a lot.
bestbeforetoday (Thu, 05 Dec 2019 15:45:57 GMT):
If you do then there is an example of usage mentioned in my first reply in this thread, but for reference:
- https://github.com/hyperledger/fabric-gateway-java/blob/master/src/test/java/org/hyperledger/fabric/gateway/sample/SampleCommitHandler.java
icordoba (Thu, 05 Dec 2019 15:56:35 GMT):
@bestbeforetoday Sorry again. I use org.hyperledger.fabric.sdk.HFClient class to create a transaction proposal which then I use org.hyperledger.fabric.sdk.Channel to send the transaction to the channel. sorry I don't find Network or Gateway objects from there. Any directions? Thanks
bestbeforetoday (Thu, 05 Dec 2019 16:01:56 GMT):
When calling `sendTransaction` to send the proposal responses to the orderer, you can pass options, which include configuring nOfEvents:
- https://sdkjavadocs.github.io/org/hyperledger/fabric/sdk/Channel.html#sendTransaction-java.util.Collection-org.hyperledger.fabric.sdk.Channel.TransactionOptions-
This can make it wait for a certain number of commit events before the Future completes
icordoba (Thu, 05 Dec 2019 16:03:11 GMT):
OK, this means I don't need to use listener approach right? Just wait for that Completable future?
bestbeforetoday (Thu, 05 Dec 2019 16:03:53 GMT):
Alternatively you can roll your own by specifying `nofNoEvents` to have the send unblock immediately and then attach a block listener to listen for commit events that you care about using `Channel.registerBlockListener()`:
- https://sdkjavadocs.github.io/org/hyperledger/fabric/sdk/Channel.html#registerBlockListener-org.hyperledger.fabric.sdk.BlockListener-
icordoba (Thu, 05 Dec 2019 16:04:26 GMT):
The "certain number of commit events" works for me I guess. I'll try that.
bestbeforetoday (Thu, 05 Dec 2019 16:05:31 GMT):
Yes, if all you care about is receiving commit events from certain peers (or a certain number of events), you can use the nOfEvents mechanism. Just take care that it doesn't deal with peers not being available or disconnecting. The high level API does deal with these cases
icordoba (Thu, 05 Dec 2019 16:05:48 GMT):
ok cool. thanks

bestbeforetoday (Wed, 11 Dec 2019 09:57:58 GMT):
@Purbaja There should not be any timeout and your listener should continue receiving events either until it is disconnected or your client application is shut down. One thing you could try is... when you listener appears to stop receiving events, grab the result of calling `toString()` on the associated Network object, and post that in a Jira mentioning that your listener is not receiving events: https://jira.hyperledger.org/projects/FGJ

I have a question.. for a chaincodeEvent if the associated chaincode is deployed/installed in two peers, then will both the peers get the event through contractListener? Or only one peer will get the event at a time?
bestbeforetoday (Thu, 12 Dec 2019 13:54:28 GMT):
The contract listener will only get the chaincode event once

Fabric-ca using java-gateway-sdk
Requirement:
My requirement is to do the register, enroll operations in fabric-ca using java-gateway-sdk.
What I have tried:
Started the fabric-ca server in a vm(say vm1). Tried to access the fabric-ca server from another vm(say vm2). I can able to enroll the admin, register and enroll the user using api. I also got the result in server after register and enroll processes as:
POST /api/v1/enroll 201 0 "OK" (admin enrollment)
POST /api/v1/cainfo 200 0 "OK"
POST /api/v1/register 201 0 "OK" (user registration)
signed certificate with serial number 75758730054339427289657557776062433601010825862
POST /api/v1/enroll 201 0 "OK" (user enrollment)
So We can assume that, vm1 can receive the enroll and register request from vm2.
Now the problem is, the generated certificates after the enrollment of the user has got stored in the wallet in the vm2 itself(that is, from where I done the api request for register and enrollment). Actually, I need that certificates to get stored in vm1(where the fabric-ca server is running). Can anyone guide me on this? Please reply asap.
Paradox-AT (Mon, 16 Dec 2019 11:20:14 GMT):
You will get the certificate where the client is running. In your case the client is running on VM2 so it got stored there

If you need it in VM1 run your client and server on the same machine

Hi.. If I tend to use DefaultCommitHandlers in fabric gateway, how do I listen and do my own handling during commitEvents ?
sandy (Mon, 16 Dec 2019 14:55:48 GMT):
@bestbeforetoday
bestbeforetoday (Tue, 17 Dec 2019 09:51:54 GMT):
What kind of handling are you looking to do?
- If you want to take some action after the transaction has been committed on peers then just do it after the transaction submit returns.
- If you want to implement your own rules for when a transaction is considered committed from the default handlers, you can implement your own commit handler. See https://hyperledger.github.io/fabric-gateway-java/release-1.4/org/hyperledger/fabric/gateway/spi/CommitHandlerFactory.html
- Another option is to have your transactions explicitly emit events to let you know that certain things have happened. These events can include additional information. For example, a _createCar_ transaction function could emit a _carCreated_ event including the unique identifier of the newly created car. Your client can listen for these events using `Contract.addContractListener()`: https://hyperledger.github.io/fabric-gateway-java/release-1.4/org/hyperledger/fabric/gateway/Contract.html#addContractListener-java.util.function.Consumer-

In fabric-gateway-java the contract.submitTransaction() is returning only the contract response. SO, if we need the transaction hash, how to get that?
bestbeforetoday (Wed, 18 Dec 2019 09:40:45 GMT):
I would guess it timed out waiting for a service discovery response
bestbeforetoday (Wed, 18 Dec 2019 09:48:36 GMT):
Do you mean the block hash? One or more transactions get committed together in a block once they have been pushed out to committing peers by the orderer. You can add a block listener to the Network object and examine the data hash and previous block hash for each block event that arrives
Purbaja (Wed, 18 Dec 2019 09:55:58 GMT):
I need the individual transaction id
Purbaja (Wed, 18 Dec 2019 09:59:14 GMT):
like we used to get in the fabric-sdk through ProposalResponse.getTransactionID()
bestbeforetoday (Wed, 18 Dec 2019 10:46:41 GMT):
Unfortunately, as you point out, the transaction ID is not surfaced by the low level SDK until after proposal responses are received, so the high level SDK does not know in advance of the `Transaction.submit()` call what the transaction ID will be. In the Node SDK we expose this with `Transaction.getTransactionID()` because this can be generated in advance of sending the transaction proposals. In practice, this typically only gets used I to wait for commit events from that transaction, which isn't necessary because the high level SDK takes care of that for you. And if you want more control of how commit events are handled you can write your own commit handler, which gets given the transaction ID

Have you got a different use case from listening to commit events that means you need the transaction ID? If so, please could you raise a Jira describing this requirement:
- https://jira.hyperledger.org/projects/FGJ
We might be able to change the implementation so that you can get the transaction ID similar to how this is done in the Node SDK.

I am setting up a TLS enabled network on separate VMs, and testing a fabric-java-sdk based client application with this network
The network has 1 Orderer, 1 Org with 2 peers, and a Fabric - CA
I am able to register and enroll users from my client application on Fabric CA
But invoke and query fail with the error - access denied for the creator Org
I am using fabric-gateway-sdk for java
Can you please advice, how can I fix the issue?

bestbeforetoday (Fri, 20 Dec 2019 11:11:08 GMT):
It's not obvious to me what the issue is but, particularly if it does work with local docker containers, I would check all the certificates are correctly generated and configured. TLS certificates will need to correctly reflect the external host names of the nodes in the network
ShobhitSrivastava (Fri, 20 Dec 2019 12:05:31 GMT):
please check the certificate content which we received after registering via fabric-ca. We need to have signedpem. Debug the fabric sdk and check the certificate content when you are enrolling the user. I can help post christmas if you need any code snippet. Thanks
Purbaja (Fri, 20 Dec 2019 12:34:26 GMT):
Does fabric-gateway supports key externalization? i mean without using fabric-ca if we use our own CA where keys are externalized can we create wallet in fabric-gateway?
bestbeforetoday (Fri, 20 Dec 2019 14:14:16 GMT):
Wallets just hold X.509 certificates and private keys. The wallet doesn't care how the credentials are obtained. To allow connection to the network they will need to be recognised as valid network credentials, which probably means signed by whatever CA is configured for your network.

bestbeforetoday (Tue, 07 Jan 2020 11:58:51 GMT):
I am guessing that your peer is running in a Docker container on your local machine. If so, you have two options:
1. Add entries for your containers to your hosts file so they resolve to localhost, for example:
```127.0.0.1 peer1.org2.example.com
```
2. Set the environment variable `org.hyperledger.fabric.sdk.service_discovery.as_localhost` to `true` to indicate that discovered nodes should resolve as localhost

@ShrutiHK You may have a mismatch between your CA identities and your generated crypto material on the network. If you created CA Identities and then wiped and recreated your crypto-config directory without clearing out your CA Identities then using your existing CA identities would give you access denied errors.

bestbeforetoday (Fri, 17 Jan 2020 16:48:34 GMT):
Sounds like something went wrong with the install/instantiate/start of the chaincode. Perhaps the logs on the peer will give you some clues. If the peer is in a Docker container then you should be able to use `docker logs` to view them. Also look at stopped chaincode Docker containers, which might be left over if the chaincode container failed to start cleanly

After connecting to a Fabric network with `Gateway` is there a need to also add a contract listener with ` addContractListener(Consumer)` to know for sure when the transaction is complete?

Has joined the channel.
bestbeforetoday (Wed, 22 Jan 2020 09:46:33 GMT):
Absolutely not! `Contract.submitTransaction()` (and `Contract.createTransaction().submit()`) but use whatever commit handling strategy you have configured at the Gateway to wait for the transaction to be committed on peers before returning. The implementation uses `Network.addCommitHandler()` to listen for commit events (and disconnections) from relevant peers. `Contract.addContractListener()` is for listening to contract (chaincode) events emitted by transaction implementation code, so might be used to coordinate business processes or logic. For example, a transaction function that creates an order might emit an event that is received by some client code, which in turn kicks off some business process to fulfil the order
bestbeforetoday (Wed, 22 Jan 2020 09:47:24 GMT):
Do have a look at the different commit handling strategies to make sure you're using one appropriate to your situation. If none of them do exactly what you want then you can write your own custom implementation
medikent (Wed, 22 Jan 2020 18:15:46 GMT):
I suspected as much when I saw the `DefaultCommitHandlers` enum. Thank you for clarifying the behavior and purpose of `Contract.addContractListener()`.
bestbeforetoday (Thu, 23 Jan 2020 09:39:57 GMT):
You're welcome. I realise the Javadoc doesn't give any description of the context in which you might want to use each of the listener types. I figured the main Fabric docs are the place to cover these concepts since they are common to all client (and smart contract) SDKs. Now I'm wondering if the Javadoc should at least contain some context on usage. Or at the very least, the doc for `submit()` should make it clear that it will use the commit handler to determine how it will wait for commit events before returning. What do you think?
bestbeforetoday (Thu, 23 Jan 2020 09:47:17 GMT):
I've raised this Jira for the submit Javadoc anyway: https://jira.hyperledger.org/browse/FGJ-73

My chaincode running on Kubernetes has some problem and the docker instances seem to be dying frequently. After this, a new instance is started but it takes some time so first request is always lost. I am getting this error (I use Fabric Java SDK):

Until I figure out why Java chaincode Pods are respawning, how can I increase that proposal wait timeout?
I have read online that value is org.hyperledger.fabric.sdk.proposal.wait.time but how and where should I pass it to the Fabric Java SDK classes?
icordoba (Fri, 24 Jan 2020 19:16:52 GMT):
Let me ask another quesiton: I have a simple Hyperledger Fabric network with just 2 peers using Kubernetes. Peer 1 is having load issues and it periodically is respawning, which is a problem as it won't be restarted until a request is received. This first request returns timeout as it needs some time to start (I am using java chaincode) I have seen that peer2 gets no request or transaction from the orderer. How should I configure the orderer to balance transactions between both peers?
icordoba (Fri, 24 Jan 2020 19:16:56 GMT):
I also want to balance the queries to the chaincode. I am using fabric Java SDK. What is the recommended approach to distribute the queries to both peers and not just to the first one? Currently, peer 2 is completely unused by Orderer or Java SDK client.
nitishbhardwaj19 (Sun, 26 Jan 2020 08:34:15 GMT):
Have you tried enabling service discovery? It will automatically choose any available peer based on the load and availability .
nitishbhardwaj19 (Sun, 26 Jan 2020 08:37:26 GMT):
What kind of operation you are trying to perform? Is it any administration task or a simple chaincode invoke? You need to use **Admin Cert** for performing the administrative tasks like installing, instantiating chaincode
nitishbhardwaj19 (Sun, 26 Jan 2020 08:42:50 GMT):
@bestbeforetoday Thanks for your active support. Your inputs are always helpful. I am just trying to switch from fabric-sdk-java to gateway-java. I went through the API docs, looks pretty interesting and simple to use. What I couldn't find is that do we have support to perform administrative activities using Gateway? I.e. creation of channel, installation/instantiation of chaincode, join or add peers with Gateways? Or Gateways are just for invoke and query? Would be great if you can share some details about it. Thanks.

If using the _fabric-gateway_ API, you can simply select the round robin query handler when connecting your Gateway. If using the low level _fabric-sdk-java_ API then you can specify the peers a proposal should be sent to in the call to `Channel.queryByChaincode()`

Haven't heard of that. It would be cool to implement though. If it doesn't exist we should add it.
bestbeforetoday (Tue, 28 Jan 2020 16:59:47 GMT):
I don't have a very authoritative answer for you but this may help. I think the signing of proposals is all handled by the `byte[] sign(PrivateKey key, byte[] plainText)` method on the CryptoSuite set on the HFClient. Perhaps you could configure your client with your own CryptoSuite implementation with your own signing implementation. That would hook you into the `Channel.sendTransactionProposal()` flow, but it doesn't give you a mechanism to sign transaction proposals completely independently and then submit the previously signed proposals directly
nitishbhardwaj19 (Tue, 28 Jan 2020 17:02:52 GMT):

The (current) direction for Fabric as a whole seems to focus on command-line tools for administrative tasks rather than having these capabilities implemented in all of the different language SDKs.

nitishbhardwaj19 (Thu, 30 Jan 2020 04:02:52 GMT):
@medikent I think we can still do this but we have to override default _CryptoSuite_ implementation to deal with certificates and sign/verify. By overriding sign and verify we can connect to key-vault and get the transaction signed from there. Just need to make sure that we use our custom _CryptoSuite_ in transaction context other than the default one.
icordoba (Thu, 30 Jan 2020 09:58:46 GMT):
Thanks @nitishbhardwaj19 . Regarding point 1, I had joined the peers to the channel using CLI. Do I need to execute any peer channel commandto enable that service discovery in the channel? So far I have added CORE_PEER_GOSSIP_EXTERNALENDPOINT and restarted the peer.

Not that I am aware of, but the transition should be pretty seamless. The only significant changes in the low-level API are the addition of lifecycle support for administrative tasks. For the high-level API, there is a change to the Wallet API but the pattern of usage is very similar to the previous iteration. This is a good starting point for the wallet API: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Wallets.html

nitishbhardwaj19 (Mon, 03 Feb 2020 04:47:44 GMT):
Query always needs to be execute on a specific peer. If we aren't not specifying a peer then that information would be taken up from the channel object and query would be performed on all the peers of that channel. (that's what I have observed till now through java-sdk code)
nitishbhardwaj19 (Mon, 03 Feb 2020 04:48:17 GMT):
_sendTransactionProposalToENdorsers _ would be used when you try to invoke anything on the chaincode

does the java sdk have the same support for event listening that the node.js sdk does?
bestbeforetoday (Thu, 06 Feb 2020 09:32:58 GMT):
Functionally similar but the APIs are (currently) slightly different. You can add block listeners to the `Network` and contract (chaincode) event listeners to the `Contract`. All of these can be real-time, event replay or checkpointed:

ownspies (Thu, 06 Feb 2020 19:30:37 GMT):
I just did a search here but didn't find any answers. I have a Java service that talks to HLF (with Mutual TLS auth enabled). I pre-create the user in the Org CA and when the app starts it enrolls the user and receives the certificates just fine. The service can also talk to the peers just fine. When talking to the orderers, however, I receive an SSL error. I've tracked down that the service is using the TLS cert from the Org CA to do mutual TLS auth, however the orderer is expecting the certs for mutual TLS auth to be signed by the TLS CA, not the org CA. Is there a way to specify a custom key / cert pair to the Java Gateway Builder SDK for mutual TLS auth?
bestbeforetoday (Fri, 07 Feb 2020 09:18:17 GMT):
Event listening with the Gateway API you will only get each event once and in order. Checkpointing is useful if you want to resume event processing across client application invocations, so use cases might include things like:
- Resume event processing after client application crash
- Batch processing of events only at certain times of day
dan13 (Fri, 07 Feb 2020 14:13:58 GMT):
Thanks -- that approach assume there is only one listener instance for each event, right? I inadverently said "peer" instead of "client" above -- sorry for the confusion.
bestbeforetoday (Fri, 07 Feb 2020 18:05:22 GMT):
Checkpointing wasn't really designed to coordinate across multiple client application instances. Certainly the supplied file checkpointer won't work for this because it gets an exclusive lock on the file and then uses in-memory state to avoid constantly re-reading the file
bestbeforetoday (Fri, 07 Feb 2020 18:08:34 GMT):
You might be able to implement your own checkpointer to achieve the result you want. It might be worth looking at some kind of external coordination like a shared message queue or database

Hi, Im my chaincode I throw a ChaincodeException which wrap another exception. I'm working with the low level SDK and i was wondering if it is possible to get the wrapped exeception when I'm inspecting the ProposalResponse. Example: in my chaincode i have `throw new ChaincodeException("error message", new IOException("specific error")` is there a way in the SDK to access the message of the `IOException`?

The error from the peer is sent back in a message field as part of the proposal response. This is just a string. So at the client end the ChaincodeException and wrapped exception don't exist. You are just getting the exception message text.

Hi all! I'm using the Java SDK for my application, but I'm getting service discovery errors.... Any one know what happens? `Failed to discover peer endpoint information peer0.org1.example.com:7051 for chaincode`XXXXX`
Javi (Tue, 11 Feb 2020 15:13:31 GMT):
in the app, that is deployed inside a k8s cluster I'm using the `org.hyperledger.fabric.sdk.service_discovery.as_localhost``envvar as `false`
Javi (Tue, 11 Feb 2020 15:14:28 GMT):
any help would be appreciated...

icordoba (Wed, 12 Feb 2020 11:53:36 GMT):
Hello again @nitishbhardwaj19 I am still trying to have Discovery working. I have added CORE_PEER_GOSSIP_EXTERNALENDPOINT env in my peer node and restart it but I get this when I try to execute a transaction from Java SDK client: "The channel is not configured with any peers with the 'discover' role" any idea what I am missing in the node configuration? Thanks a lot
icordoba (Wed, 12 Feb 2020 12:04:18 GMT):
It seems that I need to enable the discover flat when I join a channel from a peer, how can I do this? I used the "peer join" shell command to do that, so it is already joined.

Hi, can someone please direct me a documentation link for Mutual TLS on Fabric JAVA SDK?
kmadala (Thu, 13 Feb 2020 16:10:18 GMT):
link provided in this Jira is not working. Jira URL : https://jira.hyperledger.org/browse/FABJ-513
dan13 (Fri, 14 Feb 2020 01:28:53 GMT):
also looking for same -- that link pointed to a node SDK doc anyway, which wouldn't answer the question for java
bestbeforetoday (Fri, 14 Feb 2020 14:00:11 GMT):
There is just about nothing in the way of docs for the low-level Java SDK, so this is not a great answer, but this code frmo the integration tests might help: https://github.com/hyperledger/fabric-sdk-java/blob/f97741e2bd76c7733f7f81078b4de5d42a37cf9a/src/test/java/org/hyperledger/fabric/sdkintegration/ServiceDiscoveryIT.java#L99
bestbeforetoday (Fri, 14 Feb 2020 14:01:48 GMT):
So it is setting properties on the channel that look like they define the client TLS certificate and key used by discovery for mutual auth
Antimttr (Fri, 14 Feb 2020 21:51:11 GMT):
Does the java sdk at any point directly read the network-config.yaml file?
Antimttr (Fri, 14 Feb 2020 21:51:45 GMT):
I thought not but this comment gives me a reason to question that assumption: ```
# Any properties with an "x-" prefix will be treated as application-specific, exactly like how naming
# in HTTP headers or swagger properties work. The SDK will simply ignore these fields and leave
# them for the applications to process. This is a mechanism for different components of an application
# to exchange information that are not part of the standard schema described below. In particular,
# the "x-type" property with the "hlfv1" value example below is used by Hyperledger Composer to
# determine the type of Fabric networks (v0.6 vs. v1.0) it needs to work with.
```
davidkel (Fri, 14 Feb 2020 22:20:25 GMT):
network-config.yaml is an example of a connection profile. The java-sdk will only parse a connection profile if you choose to use the apis that parse a connection profile to create your channel and peer objects. You can create the channel and peer objects yourself in your code.
Antimttr (Fri, 14 Feb 2020 22:21:33 GMT):
hmm i dont think i chose those apis? but im not really sure which api's you're referring to so I cant be sure
Antimttr (Fri, 14 Feb 2020 22:22:21 GMT):
are you talking about like that gateway thingy?
Antimttr (Fri, 14 Feb 2020 22:22:25 GMT):
i know i dont use that
davidkel (Fri, 14 Feb 2020 22:24:48 GMT):
The fabric-gateway-java probably mandates the use of a connection profile (don't know if it supports what you can do in the node sdk). However the fabric-sdk-java allows you to either use a connection profile or to create channel/peer/orderer objects programatically
Antimttr (Fri, 14 Feb 2020 22:25:30 GMT):
yes, and thats what i do
Antimttr (Fri, 14 Feb 2020 22:25:55 GMT):
the channels and chaincode are all installed using sdk calls
Antimttr (Fri, 14 Feb 2020 22:26:06 GMT):
ok thanks for clarifying!
dan13 (Sat, 15 Feb 2020 21:57:18 GMT):
@bestbeforetoday thanks for the response. So, we can do something like
```Network network = gateway.getNetwork(channelName);
Properties sdprops = new Properties();
//set mutual TLS props per https://github.com/hyperledger/fabric-sdk-java/blob/f97741e2bd76c7733f7f81078b4de5d42a37cf9a/src/test/java/org/hyperledger/fabric/sdkintegration/ServiceDiscoveryIT.java#L99
network.getChannel().setServiceDiscoveryProperties(sdprops```
?

Hi All, I am facing issue in working with 2.0 version of fabirc-sdk-java. I am making use of basic-network from fabric-sample. I am able to initialize the channel, install the chaincode, approve the chaincode, but once I execute any smart contract, it is saying my chaincode is not defined on channel. Let me know. I am using 2.0 enabled channel capabilities.

Any suggestion?

Anyone seen this: the same peer is being added the the Java Gateway SDK ServiceDiscovery list multiple times because a duplicate entry (proof below) is added under a new ID every time a new event is received from the peer (this is simple local network, single peer, HF 1.4). I have a vague recollection that it was reported before but I cannot find (if it was)

Antimttr (Thu, 20 Feb 2020 22:09:12 GMT):
When you setup an orderer object in the sdk you need to specify a few properties and pass them into the orderer constructor. I was wondering for the properties `clientCertFile` and `clientKeyFile` why in the end2endit test does it use a user's (Admin@example.com) tls cert and key instead of the orderers tls and key?
Antimttr (Thu, 20 Feb 2020 22:12:05 GMT):
there's also the `pemFile` property which is set to the orderer's tls-msp server.crt file. when i attempt to create the channel and send the envelope to the orderer i get `Caused by: java.security.cert.CertificateException: No name matching orderer1.example.com found` Now i checked the certificate specified by the pemFile ```

ownspies (Fri, 21 Feb 2020 21:03:57 GMT):
@Antimttr the CN needs to be `orderer1.example.com`, or you need `DNS:orderer1.example.com` in the `X509v3 Subject Alternative Name:` attributes
ownspies (Fri, 21 Feb 2020 21:04:52 GMT):
Also, the only `O=example.com` I see is for the issuer, not for the subject, those are two totally different things
ownspies (Fri, 21 Feb 2020 21:05:20 GMT):
one last note, the `"hf.EnrollmentID":"orderer1"` typically needs to contain the full hostname for HLF nodes, so `"hf.EnrollmentID":"orderer1.example.com"`

I've spent about four months getting it all working, have bounced between standalone CAs, AWS Private CA + HLF Hierarchy, Vault CA for TLS, and straight openSSL... Have a crazy menagerie of scripts now as a result... My way of saying "I feel you're pain"
ShrutiHK (Mon, 24 Feb 2020 04:57:00 GMT):
Hi,
We are working with java-sdk but while invoking chaincodes, sometimes we get the error - GatewayException: 'Failed to discover peer endpoint '.
What can be done to avoid this error?
ShrutiHK (Mon, 24 Feb 2020 04:57:22 GMT):
Any pointers on this are appreciated. Thanks in advance.
ShrutiHK (Mon, 24 Feb 2020 05:28:45 GMT):
Kindly let me know in case someone has encountered this error
nitishbhardwaj19 (Tue, 25 Feb 2020 07:59:03 GMT):
Hi,
Could anyone share few details about the default CryptoSuite which is being used in Java-sdk.
`public byte[] sign(PrivateKey key, byte[] data)
`
This method is being override in CryptoPrimitives which is being used to sign the transaction. I am not sure about:
1) If the *byte data is actually the transaction data byte or if it's the bytes of the hash of the tx data*.
2) *What's the default hash algorithm being used to compute tx hash.*
Would be great if someone can share their thoughts on this.

Hi All! I'm trying to use the Fabric Gateway
ascatox (Wed, 26 Feb 2020 13:16:42 GMT):
using the documentation
ascatox (Wed, 26 Feb 2020 13:17:04 GMT):

Antimttr (Wed, 26 Feb 2020 18:55:24 GMT):
hey @ownspies , so finally had a chance to revist this issue today.
Antimttr (Wed, 26 Feb 2020 18:55:52 GMT):
I went ahead and deleted all the erroneous crypto material and the fabric-ca-server databases for the servers
ownspies (Wed, 26 Feb 2020 18:55:54 GMT):
how did it work out?
Antimttr (Wed, 26 Feb 2020 18:56:01 GMT):
well i got the CN corrected
Antimttr (Wed, 26 Feb 2020 18:56:15 GMT):
but the certificates the fa-ca-server is issueing still has the O=Hyperledger
Antimttr (Wed, 26 Feb 2020 18:56:21 GMT):
instead of org1.example.com
ownspies (Wed, 26 Feb 2020 18:56:28 GMT):
ugh, my wife would kill me... should have said "I feel YOUR pain" .... not "you're pain"
Antimttr (Wed, 26 Feb 2020 18:56:41 GMT):
also the locales im setting aren't taking when i enroll
Antimttr (Wed, 26 Feb 2020 18:56:54 GMT):
i checked the root ca certificate
Antimttr (Wed, 26 Feb 2020 18:56:59 GMT):
and its all correct their
Antimttr (Wed, 26 Feb 2020 18:57:15 GMT):
i changed the CSR config section in the fabric-ca-server.yaml file
Antimttr (Wed, 26 Feb 2020 18:57:25 GMT):
to match what i want the O and locales to be
Antimttr (Wed, 26 Feb 2020 18:57:31 GMT):
but it doesnt seem to be pulling it from their
Antimttr (Wed, 26 Feb 2020 18:57:31 GMT):
but it doesnt seem to be pulling it from there
ownspies (Wed, 26 Feb 2020 18:58:12 GMT):
so are you changing the fabric-ca-server-config.yaml file ?

ownspies (Wed, 26 Feb 2020 18:59:19 GMT):
not sure that is a valid O value
ownspies (Wed, 26 Feb 2020 19:00:03 GMT):
and your custom file ... is located at `FABRIC_CA_SERVER_HOME=/etc/hyperledger/fabric-ca/fabric-ca-server-config.yaml`?
Antimttr (Wed, 26 Feb 2020 19:00:19 GMT):
right that's the volume im assigning for it
ownspies (Wed, 26 Feb 2020 19:02:08 GMT):
what command do you use to register a new entity ?
Antimttr (Wed, 26 Feb 2020 19:10:01 GMT):
sec i got my boss here
Antimttr (Wed, 26 Feb 2020 19:57:08 GMT):
ok trying to reconstruct the registration command, i have it scripted
Antimttr (Wed, 26 Feb 2020 19:57:15 GMT):
but its pretty straight forward
Antimttr (Wed, 26 Feb 2020 19:57:26 GMT):
right out of the fabric-ca-server ops guide
Antimttr (Wed, 26 Feb 2020 19:59:03 GMT):
so heres an example of the registration command for my org1's first peer: fabric-ca-client register -d --id.name peer1.org1.example.com --id.secret peer1PW --id.type peer -u https://0.0.0.0:7054
Antimttr (Wed, 26 Feb 2020 19:59:03 GMT):
so heres an example of the registration command for my org1's first peer: `fabric-ca-client register -d --id.name peer1.org1.example.com --id.secret peer1PW --id.type peer -u https://0.0.0.0:7054`
ownspies (Wed, 26 Feb 2020 19:59:32 GMT):
and you run that from inside the fabric CA container ?
Antimttr (Wed, 26 Feb 2020 19:59:54 GMT):
no i run that from host command line using fabric-ca-client
Antimttr (Wed, 26 Feb 2020 20:00:11 GMT):
but it connects to my fabric-ca-server container
ownspies (Wed, 26 Feb 2020 20:00:13 GMT):
ok
Antimttr (Wed, 26 Feb 2020 20:00:23 GMT):
the 0.0.0.0 is replaced with the proper socket
Antimttr (Wed, 26 Feb 2020 20:00:48 GMT):
could it be the fabric-ca-client config?
Antimttr (Wed, 26 Feb 2020 20:01:05 GMT):
i noticed it creates a new yaml file for the client each time i run it
ownspies (Wed, 26 Feb 2020 20:01:15 GMT):
well, the first two things I would check are a) fabric-ca-server isn't loading the config file you thought it was loading and so is missing the options you set or b) there are other ENV variables overriding the config file
Antimttr (Wed, 26 Feb 2020 20:01:37 GMT):
its actually created the server.yaml file
ownspies (Wed, 26 Feb 2020 20:02:00 GMT):
it should load the config file from the FABRIC_CA_SERVER_HOME
Antimttr (Wed, 26 Feb 2020 20:02:02 GMT):
if i remove it from the fabric-ca-server working directory it will create it from new, then i just edit the existing one and restart the container
Antimttr (Wed, 26 Feb 2020 20:02:13 GMT):
right, exactly,
Antimttr (Wed, 26 Feb 2020 20:02:33 GMT):
i have it mapped to a volume: ./ca/:/etc/hyperledger/fabric-ca
ownspies (Wed, 26 Feb 2020 20:02:51 GMT):
I would enable `FABRIC_LOGGING_SPEC=debug` and restart the CA to confirm it is loading the correct config file
ownspies (Wed, 26 Feb 2020 20:03:00 GMT):
do that env var inside the docker container
Antimttr (Wed, 26 Feb 2020 20:03:02 GMT):
already have that set
Antimttr (Wed, 26 Feb 2020 20:03:14 GMT):
i have the full log in my buffer
Antimttr (Wed, 26 Feb 2020 20:03:21 GMT):
lets see if i can find where it loads the config
ownspies (Wed, 26 Feb 2020 20:03:34 GMT):
you have both the one I sent and `FABRIC_CA_SERVER_DEBUG` from your docker-compose ?
Antimttr (Wed, 26 Feb 2020 20:03:41 GMT):
```2020/02/26 17:33:44 [DEBUG] Home directory: /etc/hyperledger/fabric-ca
2020/02/26 17:33:44 [INFO] Configuration file location: /etc/hyperledger/fabric-ca/fabric-ca-server-config.yaml
2020/02/26 17:33:44 [INFO] Starting server in home directory: /etc/hyperledger/fabric-ca
```
Antimttr (Wed, 26 Feb 2020 20:04:02 GMT):
oh i see
Antimttr (Wed, 26 Feb 2020 20:04:08 GMT):
ok they're different
Antimttr (Wed, 26 Feb 2020 20:04:10 GMT):
let me try that
ownspies (Wed, 26 Feb 2020 20:05:09 GMT):
They may do the same thing; IIRC FABRIC_LOGGING_SPEC is the go forward and all others are deprecated
ownspies (Wed, 26 Feb 2020 20:05:54 GMT):
so after you start the CA if you `cat /etc/hyperledger/fabric-ca/fabric-ca-server-config.yaml` does it include your changes? Also, I thought the CA output all the options it used, but I may be thinking of something else ....
ownspies (Wed, 26 Feb 2020 20:06:06 GMT):
if it does output the options then I would compare those against what I set
Antimttr (Wed, 26 Feb 2020 20:06:30 GMT):
it does print some stuff, but let me try it with the new flag, i didnt see like OU, O, CN stuff previously
ownspies (Wed, 26 Feb 2020 20:06:43 GMT):
I admit to having a hard time here (chat) troubleshooting - there are very often hints to the real problem scattered in the log output, and just grabbing the last few lines is misleading
Antimttr (Wed, 26 Feb 2020 20:08:36 GMT):
ok heres the whole log since restarting
Antimttr (Wed, 26 Feb 2020 20:09:02 GMT):
Antimttr - Wed Feb 26 2020 12:08:50 GMT-0800 (Pacific Standard Time).txt
Antimttr (Wed, 26 Feb 2020 20:11:41 GMT):
i dont see anything in their about loading csr section
ownspies (Wed, 26 Feb 2020 20:11:46 GMT):
question for you
ownspies (Wed, 26 Feb 2020 20:11:55 GMT):
earlier in the chat you said `i changed the CSR config section in the fabric-ca-server.yaml file`
Antimttr (Wed, 26 Feb 2020 20:11:57 GMT):
also the comments above the csr section say they're only used in generated the rootca cert
ownspies (Wed, 26 Feb 2020 20:12:04 GMT):
was that just short hand ?
ownspies (Wed, 26 Feb 2020 20:12:21 GMT):
because the config file should be called `fabric-ca-server-config.yaml` and not `fabric-ca-server.yaml`
Antimttr (Wed, 26 Feb 2020 20:12:40 GMT):
oh you're right, that is what its called
Antimttr (Wed, 26 Feb 2020 20:13:32 GMT):
```# Certificate Signing Request (CSR) section.
# This controls the creation of the root CA certificate.```
Antimttr (Wed, 26 Feb 2020 20:13:42 GMT):
see but im supplying the root certificate not creating it
Antimttr (Wed, 26 Feb 2020 20:13:55 GMT):
and the ca cert im supplying has all the correct data
ownspies (Wed, 26 Feb 2020 20:14:17 GMT):
is this a root CA or an intermediate CA ?
Antimttr (Wed, 26 Feb 2020 20:14:52 GMT):
well i mean its an openssl root but it is the highest fabric-ca-server in the chain
Antimttr (Wed, 26 Feb 2020 20:15:28 GMT):
there is no fabric-ca-server above it but theirs an openssl certificate that i call the root which is what signed the ica's cert
Antimttr (Wed, 26 Feb 2020 20:15:48 GMT):
following this guide: https://medium.com/ibm-garage/using-3rd-party-root-cas-in-hyperledger-fabric-3cafa91d1260
ownspies (Wed, 26 Feb 2020 20:15:52 GMT):
ok, so you have openssl root cert and use that to sign the cert for the HFL CA ?
Antimttr (Wed, 26 Feb 2020 20:16:01 GMT):
yes
ownspies (Wed, 26 Feb 2020 20:16:54 GMT):
and the HLF CA has the wrong O / OU ?
Antimttr (Wed, 26 Feb 2020 20:17:13 GMT):
the cert im using for it looks correct to me, ill paste it here
ownspies (Wed, 26 Feb 2020 20:18:04 GMT):
so the cert issued _by_ the HLF CA has the wrong O / OU, right?
ownspies (Wed, 26 Feb 2020 20:18:18 GMT):
meaning like the orderer cert or the peer cert, or the admin cert?
Antimttr (Wed, 26 Feb 2020 20:18:27 GMT):
right
Antimttr (Wed, 26 Feb 2020 20:18:33 GMT):
so heres my ica's cert:

ownspies (Wed, 26 Feb 2020 20:19:24 GMT):
yeah, ok, that cert looks fine and yes, it's the peer cert that has the wrong O
Antimttr (Wed, 26 Feb 2020 20:19:31 GMT):
right
Antimttr (Wed, 26 Feb 2020 20:19:45 GMT):
so the cert that ca generates has O=Hyperledger
Antimttr (Wed, 26 Feb 2020 20:19:53 GMT):
which is like the default from the config.yaml
ownspies (Wed, 26 Feb 2020 20:19:58 GMT):
yeah, ok
ownspies (Wed, 26 Feb 2020 20:20:42 GMT):
so I use this command, which is effectively the same you're using
ownspies (Wed, 26 Feb 2020 20:20:47 GMT):
``````
ownspies (Wed, 26 Feb 2020 20:20:47 GMT):
```fabric-ca-client register -d \
-u ${PROTO}://$CA_ADMIN:$CA_PASSWORD@$SERVICE_DNS \
-M "${ORG_PATH}/msp" \
--id.name peer-0${PEERID}.${ORGID}.${DOMAIN_SUFFIX} \
--id.secret ${ORGID}-peer-0${PEERID}_pw \
--id.type peer
```
ownspies (Wed, 26 Feb 2020 20:21:34 GMT):
let me check my CA
Antimttr (Wed, 26 Feb 2020 20:21:58 GMT):
yeah that looks the same as what im doing
ownspies (Wed, 26 Feb 2020 20:23:15 GMT):
yes, and I have this in my config, which does work:

Antimttr (Wed, 26 Feb 2020 20:23:22 GMT):
so i mentioned that fabric-ca-client makes a fabric-ca-client-config.yaml each time i do an enroll in the enrolling entities working dir
Antimttr (Wed, 26 Feb 2020 20:23:35 GMT):
and it seems to have all the same options as the server version
Antimttr (Wed, 26 Feb 2020 20:23:39 GMT):
but of course its all set to default
ownspies (Wed, 26 Feb 2020 20:23:44 GMT):
yeah, it's similar
ownspies (Wed, 26 Feb 2020 20:23:57 GMT):
you can override the CA and stuff on the CLI
Antimttr (Wed, 26 Feb 2020 20:24:17 GMT):
im wondering if i should configure that and specify the configured yaml when i issue a fabric-ca-client command
Antimttr (Wed, 26 Feb 2020 20:24:34 GMT):
because its just using the defaults everytime somehow overriding what ive setup on my server-config.yaml
ownspies (Wed, 26 Feb 2020 20:24:40 GMT):
I've never configured the CA client file but you can try
ownspies (Wed, 26 Feb 2020 20:24:48 GMT):
for some reason the server just isn't reading your config file properly
ownspies (Wed, 26 Feb 2020 20:24:59 GMT):
is your host OS linux or Windows ?
Antimttr (Wed, 26 Feb 2020 20:25:02 GMT):
hmm but you issue these commands in the fabric-ca-server container?
Antimttr (Wed, 26 Feb 2020 20:25:08 GMT):
that seems to be a difference
Antimttr (Wed, 26 Feb 2020 20:25:18 GMT):
my host os is centos
Antimttr (Wed, 26 Feb 2020 20:26:30 GMT):
im going to give that a shot, generate a fabric-ca-client-config.yaml and use that when issue the register and enroll commands
Antimttr (Wed, 26 Feb 2020 20:29:52 GMT):
i guess what i'd like to do is just specify this stuff in environment
Antimttr (Wed, 26 Feb 2020 20:30:24 GMT):
let me see if the docs has the env variables for the CSR config settings
ownspies (Wed, 26 Feb 2020 20:34:43 GMT):
the CSR stuff as ENV is a small PITA because it's an array, not a straight string
Antimttr (Wed, 26 Feb 2020 20:34:50 GMT):
yeah
Antimttr (Wed, 26 Feb 2020 20:35:05 GMT):
im only seeing 2: FABRIC_CA_SERVER_CSR_CN and FABRIC_CA_SERVER_CSR_HOSTS
ownspies (Wed, 26 Feb 2020 20:35:11 GMT):
I found mixed docs on how to do the array, some said comma separated some said space
ownspies (Wed, 26 Feb 2020 20:35:17 GMT):
well, try that then
Antimttr (Wed, 26 Feb 2020 20:35:50 GMT):
ok so ill try setting: FABRIC_CA_SERVER_CSR_O
Antimttr (Wed, 26 Feb 2020 20:40:06 GMT):
actually i think ill do
Antimttr (Wed, 26 Feb 2020 20:40:16 GMT):
FABRIC_CA_SERVER_CSR_NAMES_O
Antimttr (Wed, 26 Feb 2020 20:40:31 GMT):
to have it match the structure
ownspies (Wed, 26 Feb 2020 20:40:48 GMT):
that makes sense
Antimttr (Wed, 26 Feb 2020 20:52:03 GMT):
ok regenerated everything time to look at my cert
ownspies (Wed, 26 Feb 2020 20:52:41 GMT):
:fingers_crossed:
Antimttr (Wed, 26 Feb 2020 20:53:46 GMT):
no change
Antimttr (Wed, 26 Feb 2020 20:54:00 GMT):
O=Hyperledger
Antimttr (Wed, 26 Feb 2020 20:55:27 GMT):
let me look at my server logs now
Antimttr (Wed, 26 Feb 2020 20:57:05 GMT):

```
Antimttr (Wed, 26 Feb 2020 20:57:13 GMT):
thats from the server log
Antimttr (Wed, 26 Feb 2020 20:57:23 GMT):
and you can see its got the correct stuff in csr
Antimttr (Wed, 26 Feb 2020 20:57:45 GMT):
`Signing:0xc0001f73e0 CSR:{CN:ica.org1.example.com Names:[{C:US ST:California L:San Diego O:org1.example.com OU:Fabric SerialNumber:}] Hosts:[0.0.0.0 3.x.7x.136] `
Antimttr (Wed, 26 Feb 2020 20:58:05 GMT):
and thats reflected in the generated cert, the issuer O is correct
Antimttr (Wed, 26 Feb 2020 20:58:09 GMT):
just not the subject O
ownspies (Wed, 26 Feb 2020 20:59:59 GMT):
so ... that is the cert for your ICA
Antimttr (Wed, 26 Feb 2020 21:00:10 GMT):
yeah
ownspies (Wed, 26 Feb 2020 21:00:18 GMT):
that has no bearing on the cert for the peer when you run the register command
Antimttr (Wed, 26 Feb 2020 21:00:28 GMT):
apparently not
Antimttr (Wed, 26 Feb 2020 21:01:44 GMT):
but it does show that the ca-server is atleast using the correct values
Antimttr (Wed, 26 Feb 2020 21:01:59 GMT):
how to get the correct values into the enrolled certificate is the question
ownspies (Wed, 26 Feb 2020 21:02:32 GMT):
uggh, sorry, let me test something locally
ownspies (Wed, 26 Feb 2020 21:05:17 GMT):
Mine say that too .... when I enroll
Antimttr (Wed, 26 Feb 2020 21:05:34 GMT):
says what? O=Hyperledger ?
ownspies (Wed, 26 Feb 2020 21:05:42 GMT):
`Subject: C = US, ST = North Carolina, O = Hyperledger, OU = client, CN = admin`
Antimttr (Wed, 26 Feb 2020 21:05:50 GMT):
ahh
ownspies (Wed, 26 Feb 2020 21:06:08 GMT):
testing something else ...
Antimttr (Wed, 26 Feb 2020 21:06:35 GMT):
well i havent tested out anything since i changed the CN
Antimttr (Wed, 26 Feb 2020 21:06:42 GMT):
maybe that's all it needs
ownspies (Wed, 26 Feb 2020 21:08:02 GMT):
`Subject: C = US, ST = California, L = San Diego, O = Testing, OU = client, CN = Justin`
ownspies (Wed, 26 Feb 2020 21:08:43 GMT):
yes in the fabric-ca-client-config.yaml (or using the corresponding env vars) set
ownspies (Wed, 26 Feb 2020 21:09:50 GMT):
so
ownspies (Wed, 26 Feb 2020 21:10:02 GMT):
`FABRIC_CA_CLIENT_CSR_NAMES_O=...`
ownspies (Wed, 26 Feb 2020 21:10:17 GMT):
and so on
Antimttr (Wed, 26 Feb 2020 21:11:01 GMT):
oh shoot i was using FABRIC_CA_SERVER not _CLIENT :disappointed_relieved:
Antimttr (Wed, 26 Feb 2020 21:13:09 GMT):
ok got to reset all this again and ill give it another go!
ownspies (Wed, 26 Feb 2020 21:15:10 GMT):
shouldn't have to reset
ownspies (Wed, 26 Feb 2020 21:15:22 GMT):
just set the env vars and register a new user
Antimttr (Wed, 26 Feb 2020 21:20:16 GMT):
still no
Antimttr (Wed, 26 Feb 2020 21:20:27 GMT):
-.-
Antimttr (Wed, 26 Feb 2020 21:20:43 GMT):
im going to review some settings, this is so strange, you're able to get it working
Antimttr (Wed, 26 Feb 2020 21:21:26 GMT):
ah shite i had a space after the NAMES_O
Antimttr (Wed, 26 Feb 2020 21:21:31 GMT):
might make a idfference
Antimttr (Wed, 26 Feb 2020 21:25:24 GMT):
bah nope still the same
Antimttr (Wed, 26 Feb 2020 21:30:29 GMT):
ok im going to try it with a custom fabric-ca-client-config.yaml
Antimttr (Wed, 26 Feb 2020 21:34:22 GMT):
@ownspies did you set that env just when you enrolled or when you registered too?
Antimttr (Wed, 26 Feb 2020 22:08:18 GMT):
aha!
Antimttr (Wed, 26 Feb 2020 22:08:38 GMT):
i got it, used --csr.names in the arguments to fabric-ca-client
Antimttr (Wed, 26 Feb 2020 22:19:28 GMT):
thanks ownspies!
ownspies (Thu, 27 Feb 2020 13:12:11 GMT):
awesome! Sorry, I got off the bus and went straight to church
ownspies (Thu, 27 Feb 2020 13:12:11 GMT):
awesome! Sorry or not responding sooner, I got off the bus and went straight to church, yada yada yada
lzaouche (Thu, 27 Feb 2020 14:44:00 GMT):
Hello, is it possible to get the name of the peer who executed a transaction? envelopeInfo.getCreator().getName() for example?
yacovm (Thu, 27 Feb 2020 15:10:08 GMT):
it's in the endorsement
yacovm (Thu, 27 Feb 2020 15:10:13 GMT):
the certificate of the peer is there
lzaouche (Thu, 27 Feb 2020 15:29:07 GMT):
I can't see anything about the transaction creator here https://javadoc.io/doc/org.hyperledger.fabric-sdk-java/fabric-sdk-java/latest/org/hyperledger/fabric/sdk/BlockInfo.EndorserInfo.html
Antimttr (Thu, 27 Feb 2020 19:59:06 GMT):
@ownspies quick update. got everything back up and running with the corrected certs now but now im running into some sort of chaining issue: `Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target` going to try the tlsca's chain certificate instead of its main cert
ownspies (Thu, 27 Feb 2020 20:24:09 GMT):
where do you get that ?
ownspies (Thu, 27 Feb 2020 20:24:27 GMT):
should have replied here - what is returning that error?
Antimttr (Thu, 27 Feb 2020 20:34:29 GMT):
the java sdk
Antimttr (Thu, 27 Feb 2020 20:34:40 GMT):
when im attempting to send a transaction to the orderer
ownspies (Thu, 27 Feb 2020 20:34:59 GMT):
Ohhh we just went through that....
Antimttr (Thu, 27 Feb 2020 20:35:01 GMT):
org.hyperledger.fabric.sdk.OrdererClient.sendTransaction(OrdererClient.java:236)
Antimttr (Thu, 27 Feb 2020 20:35:07 GMT):
right but different error message
ownspies (Thu, 27 Feb 2020 20:35:12 GMT):
Ahh yes, the TLS CA files have to be included in the network config JSON file
Antimttr (Thu, 27 Feb 2020 20:35:14 GMT):
still a tls error though
Antimttr (Thu, 27 Feb 2020 20:35:25 GMT):
yes they are
ownspies (Thu, 27 Feb 2020 20:35:27 GMT):
yeah, sorry, I mean my team just went through that same problem
Antimttr (Thu, 27 Feb 2020 20:35:47 GMT):
but my tlsca is chained
ownspies (Thu, 27 Feb 2020 20:35:49 GMT):
is your TLS CA comprised of more than one parent, meaning is it Root -> Intermediate -> Peer Cert
Antimttr (Thu, 27 Feb 2020 20:35:56 GMT):
im wodnering if i need to supply the chain cert
ownspies (Thu, 27 Feb 2020 20:36:04 GMT):
yes you need to include the chain cert in the JSON
Antimttr (Thu, 27 Feb 2020 20:36:04 GMT):
yes
ownspies (Thu, 27 Feb 2020 20:36:17 GMT):
not the TLS cert for the server, just the chain
Antimttr (Thu, 27 Feb 2020 20:36:24 GMT):
does it use a different key name or still
Antimttr (Thu, 27 Feb 2020 20:36:26 GMT):
tlsCACerts
ownspies (Thu, 27 Feb 2020 20:37:07 GMT):
``` "orderers": {
"orderer-01.dev.example.net:7050": {
"url": "grpcs://orderer-01.dev.example.net:7050",
"tlsCACerts": {
"pem": "-----BEGIN CERTIFICATE-----\nMIICmzCCxxxxxxxxxxxxxxxxUrk=\n-----END CERTIFICATE-----\n"
}
},
```
ownspies (Thu, 27 Feb 2020 20:37:29 GMT):
you have to do that for each orderer and each peer
Antimttr (Thu, 27 Feb 2020 20:38:16 GMT):
i diff'd the cert thats in `crypto-config/ordererOrganizations/example.com/tlsca/tls.example.com.crt.pem` and the one in the orderer directory : `crypto-config/ordererOrganizations/example.com/orderers/orderer1.example.com/tls-msp/tlscacerts/cert.pem`
Antimttr (Thu, 27 Feb 2020 20:38:21 GMT):
and they are completely different certs
Antimttr (Thu, 27 Feb 2020 20:38:29 GMT):
which i was confused by because i thought they would be the same
Antimttr (Thu, 27 Feb 2020 20:38:31 GMT):
but i guess not
ownspies (Thu, 27 Feb 2020 20:38:51 GMT):
tls-msp - is that standard?
ownspies (Thu, 27 Feb 2020 20:38:56 GMT):
I've never seen that dir
Antimttr (Thu, 27 Feb 2020 20:39:07 GMT):
thats what they used in the fabric-ca-server ops guide
Antimttr (Thu, 27 Feb 2020 20:39:16 GMT):
which is what i used to build the msp
ownspies (Thu, 27 Feb 2020 20:39:20 GMT):
hmm, didn't RTFM that one
ownspies (Thu, 27 Feb 2020 20:39:39 GMT):
I use the cert from tlsca
Antimttr (Thu, 27 Feb 2020 20:39:42 GMT):
are they different in your setup to?
ownspies (Thu, 27 Feb 2020 20:39:56 GMT):
no, I have a simplified TLS setup
ownspies (Thu, 27 Feb 2020 20:39:57 GMT):
just
ownspies (Thu, 27 Feb 2020 20:40:10 GMT):
root -> intermediate -> tls parent ->
ownspies (Thu, 27 Feb 2020 20:40:10 GMT):
root -> intermediate -> tls parent ->
ownspies (Thu, 27 Feb 2020 20:41:13 GMT):
the certs have to be in a specific order too...
ownspies (Thu, 27 Feb 2020 20:41:18 GMT):
when they are chained
Antimttr (Thu, 27 Feb 2020 20:41:24 GMT):
yes according to the ops guide
Antimttr (Thu, 27 Feb 2020 20:41:36 GMT):
actually according to the medium article i used
Antimttr (Thu, 27 Feb 2020 20:41:57 GMT):
i first cat the intermediate signing cert, then the rca cert
Antimttr (Thu, 27 Feb 2020 20:42:06 GMT):
so child, parent
ownspies (Thu, 27 Feb 2020 20:42:18 GMT):
do you just have two certs above the server TLS cert ?
Antimttr (Thu, 27 Feb 2020 20:42:33 GMT):
well just one cert
Antimttr (Thu, 27 Feb 2020 20:42:37 GMT):
the root cert
ownspies (Thu, 27 Feb 2020 20:42:43 GMT):
and it signs all the TLS certs ?
ownspies (Thu, 27 Feb 2020 20:42:45 GMT):
so its
Antimttr (Thu, 27 Feb 2020 20:42:48 GMT):
then the tls fabric-server's cert
ownspies (Thu, 27 Feb 2020 20:43:06 GMT):
root -> ...
or
root -> ?
ownspies (Thu, 27 Feb 2020 20:43:06 GMT):
root -> ...
and
root -> ?
Antimttr (Thu, 27 Feb 2020 20:43:33 GMT):
rca.example.com -> tls.example.com -> orderer1.example.com
ownspies (Thu, 27 Feb 2020 20:44:05 GMT):
ok, so your TLS chain file should include (in this order) tls.example.com+rca.example.com
Antimttr (Thu, 27 Feb 2020 20:44:16 GMT):
ok
Antimttr (Thu, 27 Feb 2020 20:45:06 GMT):
i have that certificate already in my example.com/tlsca dir
Antimttr (Thu, 27 Feb 2020 20:45:29 GMT):
ill set that as the tlscacert in the network-config.yaml
Antimttr (Thu, 27 Feb 2020 20:45:31 GMT):
and try again
Antimttr (Thu, 27 Feb 2020 20:48:21 GMT):
hmm now i got `javax.net.ssl.SSLHandshakeException: error:0b000074:X.509 certificate routines:OPENSSL_internal:KEY_VALUES_MISMATCH`
Antimttr (Thu, 27 Feb 2020 20:49:30 GMT):
im wondering if in the docker environment if ORDERER_GENERAL_TLS_ROOTCAS needs to also contain this chain cert
Antimttr (Thu, 27 Feb 2020 20:49:48 GMT):
right now its pointing to the tlscacert in the orderer directory
Antimttr (Thu, 27 Feb 2020 21:43:06 GMT):
ok so set the orderers docker yaml config to point ORDERER_GENERAL_TLS_ROOTCAS to the chain cert as well, but didnt make any difference
ownspies (Fri, 28 Feb 2020 14:22:59 GMT):
So it's hard to help without combing through all the config files, but what I had to do with issues like this is I would retrieve the cert from the orderer using `openssl s_client -connect google.com:443` (obviously use the correct host/port) and I would save the cert locally
ownspies (Fri, 28 Feb 2020 14:23:21 GMT):
Then I would use the local TLS certs to verify the certificate
ownspies (Fri, 28 Feb 2020 14:23:49 GMT):
since you have chained certs, create a new directory and put each certificate into a separate file in that directory
ownspies (Fri, 28 Feb 2020 14:24:01 GMT):
and put the downloaded orderer cert into the directory above that
ownspies (Fri, 28 Feb 2020 14:24:52 GMT):
and run `openssl verify -CAfile chain/root.pem o.pem`
ownspies (Fri, 28 Feb 2020 14:24:52 GMT):
run `openssl verify -CAfile chain.pem orderer.pem`
ownspies (Fri, 28 Feb 2020 14:27:26 GMT):
e.g. I ran this locally:"
ownspies (Fri, 28 Feb 2020 14:27:26 GMT):
e.g. I ran this locally:
ownspies (Fri, 28 Feb 2020 14:28:10 GMT):
```openssl verify -CAfile tlsca/tls.sit.example.net-chain.pem orderers/orderer-01.sit.example.net/tls/orderer-01.sit.example.net-cert.pem
orderers/orderer-01.sit.champgrid.net/tls/orderer-01.sit.champgrid.net-cert.pem: OK
```
ownspies (Fri, 28 Feb 2020 14:28:10 GMT):
```openssl verify -CAfile tlsca/tls.sit.example.net-chain.pem orderers/orderer-01.sit.example.net/tls/orderer-01.sit.example.net-cert.pem
orderers/orderer-01.sit.example.net/tls/orderer-01.sit.example.net-cert.pem: OK
```
ownspies (Fri, 28 Feb 2020 14:28:59 GMT):
doing this tells you exactly which cert chain to use with your orderers
Antimttr (Fri, 28 Feb 2020 15:36:47 GMT):
oh
Antimttr (Fri, 28 Feb 2020 15:36:49 GMT):
very nice!
Antimttr (Fri, 28 Feb 2020 15:36:54 GMT):
ok im going to try that, thanks

ownspies (Fri, 28 Feb 2020 15:42:45 GMT):
yup, save that `---BEGIN CERTIFI...` to the `---END CERT...`
Antimttr (Fri, 28 Feb 2020 15:43:22 GMT):
ok saved that
Antimttr (Fri, 28 Feb 2020 15:43:43 GMT):
now ill verify
ownspies (Fri, 28 Feb 2020 15:43:47 GMT):
yup
Antimttr (Fri, 28 Feb 2020 15:44:51 GMT):
```$ openssl verify -CAfile chain.example.com.crt.pem ~/tmp/orderer.pem
/home/m____/tmp/orderer.pem: OK
```
Antimttr (Fri, 28 Feb 2020 15:44:58 GMT):
so that works
Antimttr (Fri, 28 Feb 2020 15:45:14 GMT):
i think they're the same cert if im not mistaken
Antimttr (Fri, 28 Feb 2020 15:45:17 GMT):
let me diff them
ownspies (Fri, 28 Feb 2020 15:45:29 GMT):
yeah, you don't want to verify the cert with itself
ownspies (Fri, 28 Feb 2020 15:45:33 GMT):
you want to verify the cert chain
Antimttr (Fri, 28 Feb 2020 15:45:35 GMT):
oh no they're not
Antimttr (Fri, 28 Feb 2020 15:46:26 GMT):
hmm ok well
Antimttr (Fri, 28 Feb 2020 15:46:46 GMT):
those warnings at the begining of the first openssl command were interesting
Antimttr (Fri, 28 Feb 2020 15:47:00 GMT):
but maybe they occur just because they're not signed by a real root authority
Antimttr (Fri, 28 Feb 2020 15:47:05 GMT):
so it cant verify them that way
Antimttr (Fri, 28 Feb 2020 15:48:30 GMT):
ok so i found what cert its giving me, its the orderer.example.com/tls-msp/signcerts/cert.pem
Antimttr (Fri, 28 Feb 2020 15:48:39 GMT):
which i beleive is correct
ownspies (Fri, 28 Feb 2020 15:49:34 GMT):
ohhh so you're using the CA to register then enroll a user
ownspies (Fri, 28 Feb 2020 15:49:43 GMT):
and using that users certs for TLS
ownspies (Fri, 28 Feb 2020 15:49:46 GMT):
got it
Antimttr (Fri, 28 Feb 2020 15:49:53 GMT):
i have two fabric-ca-server's per org
Antimttr (Fri, 28 Feb 2020 15:49:58 GMT):
one is the regular one, and one is the tls
Antimttr (Fri, 28 Feb 2020 15:50:07 GMT):
they both come from independent rootcas
Antimttr (Fri, 28 Feb 2020 15:51:14 GMT):
that openssl command is handy though, i love stuff like that
ownspies (Fri, 28 Feb 2020 15:51:19 GMT):
yeah, ok, so you should have the chain files inside `tls-msp/cacerts` and `tls-msp/intermediatecerts`
Antimttr (Fri, 28 Feb 2020 15:51:24 GMT):
i had no idea you could extract the cert like that
ownspies (Fri, 28 Feb 2020 15:51:39 GMT):
yeah, I've learned a LOT about openssl commands
Antimttr (Fri, 28 Feb 2020 15:51:44 GMT):
oh and intermediatecerts?
Antimttr (Fri, 28 Feb 2020 15:51:51 GMT):
i think my intermediatecerts is empty
ownspies (Fri, 28 Feb 2020 15:51:56 GMT):
you'll join all the files from those two directories
ownspies (Fri, 28 Feb 2020 15:52:34 GMT):
and that will be your chain file
Antimttr (Fri, 28 Feb 2020 15:52:37 GMT):
nm its not empty
Antimttr (Fri, 28 Feb 2020 15:52:42 GMT):
let me see if its my chain file though
Antimttr (Fri, 28 Feb 2020 15:53:06 GMT):
it is not a chain file
Antimttr (Fri, 28 Feb 2020 15:53:15 GMT):
but neither is it the same as whats in tlscacerts
ownspies (Fri, 28 Feb 2020 15:53:44 GMT):
well the file in signercerts is signed by the file in cacerts + intermediatecerts
Antimttr (Fri, 28 Feb 2020 15:54:04 GMT):
i see
ownspies (Fri, 28 Feb 2020 15:54:11 GMT):
you could validate that statement using the openssl verify command to verify the file in signercerts
Antimttr (Fri, 28 Feb 2020 15:54:14 GMT):
let me examine the cert in intermediate
ownspies (Fri, 28 Feb 2020 15:54:19 GMT):
it works a little different when you have multiple files
ownspies (Fri, 28 Feb 2020 15:54:34 GMT):
but ... basically all your TLS material you need is in that tls-msp path
Antimttr (Fri, 28 Feb 2020 15:55:12 GMT):
```$ openssl verify -CAfile tlscacerts/tls-3-14-72-136-7151.pem signcerts/cert.pem
signcerts/cert.pem: C = US, ST = California, L = San Diego, O = example.com, OU = orderer, CN = orderer1.example.com
error 20 at 0 depth lookup:unable to get local issuer certificate
```
Antimttr (Fri, 28 Feb 2020 15:55:12 GMT):
```$ openssl verify -CAfile tlscacerts/tls-3-x-72-x6-7151.pem signcerts/cert.pem
signcerts/cert.pem: C = US, ST = California, L = San Diego, O = example.com, OU = orderer, CN = orderer1.example.com
error 20 at 0 depth lookup:unable to get local issuer certificate
```
ownspies (Fri, 28 Feb 2020 15:55:56 GMT):
right - the tlsca didn't sign the signcert file
Antimttr (Fri, 28 Feb 2020 15:56:35 GMT):
should it have?
ownspies (Fri, 28 Feb 2020 15:56:46 GMT):
no
ownspies (Fri, 28 Feb 2020 15:57:01 GMT):
the files in cacerts/ and intermediatecerts/ signed that file
Antimttr (Fri, 28 Feb 2020 15:57:11 GMT):
same response if i verify the signcert with the tlscaintermediate cert
Antimttr (Fri, 28 Feb 2020 15:57:35 GMT):
i dont have any files in cacerts
Antimttr (Fri, 28 Feb 2020 15:57:38 GMT):
in the tls-msp anyways
Antimttr (Fri, 28 Feb 2020 15:57:41 GMT):
only tlscacerts
ownspies (Fri, 28 Feb 2020 15:57:49 GMT):
oh
Antimttr (Fri, 28 Feb 2020 15:58:09 GMT):
i noticed that when i enrolled tls server
ownspies (Fri, 28 Feb 2020 15:58:17 GMT):
what I output from `openssl x509 -noout -text -in signcerts/cert.pem` then ?
Antimttr (Fri, 28 Feb 2020 15:58:24 GMT):
only the tls directories in the msp it produced had anythign in them

if you do the same for the file in tlsintermediatecerts/ what do you get ?

ownspies (Fri, 28 Feb 2020 16:00:56 GMT):
ok, wasn't expecting that
Antimttr (Fri, 28 Feb 2020 16:01:29 GMT):
does that look off to you?
ownspies (Fri, 28 Feb 2020 16:06:14 GMT):
you could try
ownspies (Fri, 28 Feb 2020 16:06:48 GMT):
```openssl verify -CAfile tlscacerts/ -untrusted tlsintermediatecerts signcerts/cert.pem```
ownspies (Fri, 28 Feb 2020 16:06:48 GMT):
```openssl verify -CAfile tlscacerts/ -untrusted tlsintermediatecerts/ signcerts/cert.pem```
ownspies (Fri, 28 Feb 2020 16:07:36 GMT):
basically though the files in tlscacerts and tlsintermediatecerts are your chain - assemble those into a single file in the correct sequence and use that for your Java app
Antimttr (Fri, 28 Feb 2020 16:07:44 GMT):
`signcerts/cert.pem: OK`
ownspies (Fri, 28 Feb 2020 16:08:12 GMT):
have to jump off for a bit, but that is your chain
Antimttr (Fri, 28 Feb 2020 16:08:22 GMT):
so i just need to make it into a chain file
Antimttr (Fri, 28 Feb 2020 16:08:29 GMT):
and use that in the tlsCACerts in my network-config
Antimttr (Fri, 28 Feb 2020 16:08:34 GMT):
if i understasnd correctly
Antimttr (Fri, 28 Feb 2020 16:17:18 GMT):
ok so here's the issue, the two of those files chained together is equal to the chainfile i already have, and that file does verify the signcerts/cert.pem
Antimttr (Fri, 28 Feb 2020 16:20:24 GMT):
the error message seems to imply some sort of mismatch with the cert key file

ownspies (Fri, 28 Feb 2020 16:24:42 GMT):
so do this
ownspies (Fri, 28 Feb 2020 16:24:48 GMT):
?
Antimttr (Fri, 28 Feb 2020 16:25:05 GMT):
you know theres two other files that the sdk requires to do this transaction
Antimttr (Fri, 28 Feb 2020 16:25:13 GMT):
the clientcertfile and the clientkey file
Antimttr (Fri, 28 Feb 2020 16:25:25 GMT):
im wondering if those are off
ownspies (Fri, 28 Feb 2020 16:25:32 GMT):
https://www.ssl247.com/kb/ssl-certificates/troubleshooting/certificate-matches-private-key
Antimttr (Fri, 28 Feb 2020 16:25:38 GMT):
right now i have the clientcertfile pointing to its tlscacert
Antimttr (Fri, 28 Feb 2020 16:25:44 GMT):
which wouldnt correspond to the key file
Antimttr (Fri, 28 Feb 2020 16:25:57 GMT):
so ii tried changing it to the signcert in the Admin@example.com/tsl-msp
Antimttr (Fri, 28 Feb 2020 16:26:02 GMT):
testing now
ownspies (Fri, 28 Feb 2020 16:26:24 GMT):
compare the signcert/cert.pem with your private key in keyfiles/
Antimttr (Fri, 28 Feb 2020 16:26:37 GMT):
oh
Antimttr (Fri, 28 Feb 2020 16:26:41 GMT):
i think that did it
Antimttr (Fri, 28 Feb 2020 16:26:45 GMT):
im getting past tls handshaking now
ownspies (Fri, 28 Feb 2020 16:27:03 GMT):

hmm wondering why my admin isnt a writer

maybe i should be using the msp cert not the tls-msp cert..
Antimttr (Fri, 28 Feb 2020 16:32:29 GMT):
hmm nope didnt make a difference
Antimttr (Fri, 28 Feb 2020 16:33:06 GMT):
let me double check my genesis block config

im trying to create a new channel
Antimttr (Fri, 28 Feb 2020 16:39:44 GMT):
but i've already created a genesis block by hand outside of the sdk
Antimttr (Fri, 28 Feb 2020 16:41:44 GMT):
but thats exactly how they do it in balance-transfer
Antimttr (Fri, 28 Feb 2020 16:41:50 GMT):
and this same process works their no probllem
Antimttr (Fri, 28 Feb 2020 16:43:30 GMT):
oh shoot, they have the admin keys encoded into their first block
Antimttr (Fri, 28 Feb 2020 16:43:34 GMT):
i dont have that
Antimttr (Fri, 28 Feb 2020 16:44:21 GMT):
no nm thats their network-config not their configtx.yaml
Antimttr (Fri, 28 Feb 2020 20:45:44 GMT):
yay i finally got it!
Antimttr (Fri, 28 Feb 2020 20:45:57 GMT):
had to copy updated admin certs into my org msp's

@ownspies any chance you're about today?
ownspies (Tue, 03 Mar 2020 20:10:18 GMT):
Hey @Antimttr what's up?
Antimttr (Tue, 03 Mar 2020 20:12:23 GMT):
hey ownspies, so I'm attempting to resolve some of the crypto issues im having. When you generate your crypto do you specify the peers internal ip addresses via the SAN or via the CSR values?
Antimttr (Tue, 03 Mar 2020 20:12:55 GMT):
my peers are trying to gossip to one another but they cant resolve the hostnames: ` UTC [gossip.discovery] func1 -> WARN 37f Could not connect to Endpoint: peer1.org2.example.com:7021, InternalEndpoint: peer1.org2.example.com:7021, PKI-ID: , Metadata: : context deadline exceeded
`
Antimttr (Tue, 03 Mar 2020 20:12:55 GMT):

ownspies (Tue, 03 Mar 2020 20:13:00 GMT):
both I believe
ownspies (Tue, 03 Mar 2020 20:13:02 GMT):
let me check
ownspies (Tue, 03 Mar 2020 20:13:12 GMT):
this is the TLS for a peer, or the signer cert for a peer?
Antimttr (Tue, 03 Mar 2020 20:13:23 GMT):
both i suppose
Antimttr (Tue, 03 Mar 2020 20:13:57 GMT):
i mean i specified the public ip address of the peer in the CSR
Antimttr (Tue, 03 Mar 2020 20:14:07 GMT):
but it seems like its not using that data to try and gossip with the peer
Antimttr (Tue, 03 Mar 2020 20:14:52 GMT):
theres so much going on in the peer logs, hard to know whats normal and what needs to be addressed
Antimttr (Tue, 03 Mar 2020 20:15:53 GMT):
also seems like the peers are grabbing these ips that the host box is bound to but they're for internal use only, like in the 172.x.x.x network and it makes it so i have no idea which peer is on which ip address
ownspies (Tue, 03 Mar 2020 20:16:03 GMT):
I use the defaults for signer
ownspies (Tue, 03 Mar 2020 20:16:09 GMT):
```fabric-ca-client register -d \
-u ${PROTO}://$CA_ADMIN:$CA_PASSWORD@$SERVICE_DNS \
-M "${ORG_PATH}/msp" \
--id.name peer-0${PEERID}.${ORGID}.${DOMAIN_SUFFIX} \
--id.secret ${ORGID}-peer-0${PEERID}_pw \
--id.type peer```
ownspies (Tue, 03 Mar 2020 20:16:09 GMT):
```fabric-ca-client register -d \
-u ${PROTO}://$CA_ADMIN:$CA_PASSWORD@$SERVICE_DNS \
-M "${ORG_PATH}/msp" \
--id.name peer-0${PEERID}.${ORGID}.${DOMAIN_SUFFIX} \
--id.secret XXXXX \
--id.type peer```
Antimttr (Tue, 03 Mar 2020 20:16:15 GMT):
im thinking about just specifying a binding ip address
Antimttr (Tue, 03 Mar 2020 20:16:38 GMT):
so you dont use the -m flag at all
Antimttr (Tue, 03 Mar 2020 20:16:54 GMT):
in your SAN in the certificate do you have the hostname of the box used to run fabric-ca-client?
Antimttr (Tue, 03 Mar 2020 20:17:07 GMT):
i checked and thats what's in my SAN for all my generated certificates
ownspies (Tue, 03 Mar 2020 20:17:18 GMT):
for the TLS cert, I'm setting the SAN and the CN to the same
Antimttr (Tue, 03 Mar 2020 20:17:48 GMT):
and you're dealing with dns hostnames that actually resolve i take it?
Antimttr (Tue, 03 Mar 2020 20:17:52 GMT):
im still dealing with example.com

Antimttr (Tue, 03 Mar 2020 20:18:48 GMT):
and so what address does your gossip try and go through?
Antimttr (Tue, 03 Mar 2020 20:18:55 GMT):
does it resolve that hostname?
ownspies (Tue, 03 Mar 2020 20:18:59 GMT):
peer-01.core.sit.example.net
ownspies (Tue, 03 Mar 2020 20:19:02 GMT):
which is a load balancer
ownspies (Tue, 03 Mar 2020 20:19:14 GMT):
using TCP not HTTP/HTTPS/GPC load balancing
ownspies (Tue, 03 Mar 2020 20:19:41 GMT):
So it is LB -> K8S Service (KubeProxy) -> K8S POD
Antimttr (Tue, 03 Mar 2020 20:19:43 GMT):
so you have that hostname mapped to an ip address in the box hosting the docker containers?
Antimttr (Tue, 03 Mar 2020 20:19:46 GMT):
oh you're doing k8
ownspies (Tue, 03 Mar 2020 20:19:52 GMT):
yeah and use DNS to resolve
ownspies (Tue, 03 Mar 2020 20:20:05 GMT):
so DNS points to LB, it is updated automatically using external-dns for K8S
ownspies (Tue, 03 Mar 2020 20:20:27 GMT):
the advertised gossip address is that hostname, peer-01.sit.example.net
ownspies (Tue, 03 Mar 2020 20:20:27 GMT):
the advertised gossip address is that hostname, peer-01.sit.example.net:7051
ownspies (Tue, 03 Mar 2020 20:20:43 GMT):
Port Number may be wrong, going from mem
Antimttr (Tue, 03 Mar 2020 20:20:52 GMT):
interesting
Antimttr (Tue, 03 Mar 2020 20:21:01 GMT):
i wonder if theres some way to specify hostnames in the docker container
Antimttr (Tue, 03 Mar 2020 20:21:06 GMT):
i guess a hosts file
ownspies (Tue, 03 Mar 2020 20:21:12 GMT):
K8S automatically registers the nodes / target ports with the LB
ownspies (Tue, 03 Mar 2020 20:21:24 GMT):
you can use something, just a sec
ownspies (Tue, 03 Mar 2020 20:22:00 GMT):
https://docs.docker.com/compose/compose-file/#extra_hosts
ownspies (Tue, 03 Mar 2020 20:22:14 GMT):
you also can use the `link` option to specify a host alias
ownspies (Tue, 03 Mar 2020 20:22:31 GMT):
https://docs.docker.com/compose/compose-file/#links
ownspies (Tue, 03 Mar 2020 20:22:34 GMT):
use something like
ownspies (Tue, 03 Mar 2020 20:22:40 GMT):
```
peer:
```
ownspies (Tue, 03 Mar 2020 20:22:40 GMT):
```
peer:
links:
- orderer:orderer-01.dev.example.net
- peer-01:peer-01.dev.example.net
```
ownspies (Tue, 03 Mar 2020 20:23:24 GMT):
the left side of the colon is the service name as defined in the docker-compose, the right side is the new alias
ownspies (Tue, 03 Mar 2020 20:23:48 GMT):
this is what you use to reference other services in Docker because typically addresses are assigned dynamically, not statically
Antimttr (Tue, 03 Mar 2020 20:23:51 GMT):
ahh
Antimttr (Tue, 03 Mar 2020 20:23:52 GMT):
interesting
ownspies (Tue, 03 Mar 2020 20:24:02 GMT):
if you use static addresses in Docker, then you can use the extra_hosts option
Antimttr (Tue, 03 Mar 2020 20:24:16 GMT):
i might just do that
Antimttr (Tue, 03 Mar 2020 20:24:23 GMT):
i just want them all using the same ip address
Antimttr (Tue, 03 Mar 2020 20:24:39 GMT):
but then map that to different external hostnames
ownspies (Tue, 03 Mar 2020 20:25:29 GMT):
same IP inside docker or on the host OS ?
Antimttr (Tue, 03 Mar 2020 20:25:40 GMT):
well its the hostOS's main ip adress
ownspies (Tue, 03 Mar 2020 20:26:04 GMT):
also, for the signer certs
Antimttr (Tue, 03 Mar 2020 20:26:05 GMT):
and they all listen on it, but they seem to be trying to use their CN's to connect to eachother
Antimttr (Tue, 03 Mar 2020 20:26:34 GMT):
yeah i could add it as CSR/SAN to the signer certs
ownspies (Tue, 03 Mar 2020 20:26:49 GMT):

not sure which one it needs so ill do both
Antimttr (Tue, 03 Mar 2020 20:27:38 GMT):
its like the CSR stuff doesnt even show up in the cert
Antimttr (Tue, 03 Mar 2020 20:27:47 GMT):
is that something that just lives on fabric-ca-server db?
ownspies (Tue, 03 Mar 2020 20:28:40 GMT):
I specify custom ones
ownspies (Tue, 03 Mar 2020 20:28:45 GMT):
values for the SAN I mean
Antimttr (Tue, 03 Mar 2020 20:29:04 GMT):
yeah, im going to need to start doing that
Antimttr (Tue, 03 Mar 2020 20:29:23 GMT):
i mistakenly thought putting in ip into the CSR would put it into the SAN
ownspies (Tue, 03 Mar 2020 20:31:00 GMT):
I do set a custom CA config file
ownspies (Tue, 03 Mar 2020 20:31:08 GMT):
``` hosts:
- localhost
# K8S Service
- {{ include "hlf-ca.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
{{- if .Values.ingress.hosts }}
# Ingresses
{{- range .Values.ingress.hosts }}
- {{ . }}
{{- end }}
{{- end }}
```
ownspies (Tue, 03 Mar 2020 20:31:57 GMT):
actually, that's the CA, I need to get the peer config
ownspies (Tue, 03 Mar 2020 20:33:22 GMT):
I do set it somewhere when I register the peer, but I can't remember where I set it
ownspies (Tue, 03 Mar 2020 20:34:38 GMT):
if you need me to find that, let me know
Antimttr (Tue, 03 Mar 2020 20:34:53 GMT):
im not really sure what thats doing
Antimttr (Tue, 03 Mar 2020 20:35:05 GMT):
i mean i see it includes a new property
Antimttr (Tue, 03 Mar 2020 20:35:07 GMT):
to the certificate
Antimttr (Tue, 03 Mar 2020 20:35:26 GMT):
i havent read about those properties much yet
ownspies (Tue, 03 Mar 2020 20:35:30 GMT):
it's just Go template
ownspies (Tue, 03 Mar 2020 20:35:37 GMT):
it's just specifying the host names to use when creating a CSR
ownspies (Tue, 03 Mar 2020 20:35:37 GMT):
it's just specifying the host names to use for the SAN component when creating a CSR
ownspies (Tue, 03 Mar 2020 20:36:13 GMT):
so it includes 'localhost', the Kubernetes DNS name (that is the .svc.cluster.local part), and any hostnames assigned to the ingress
Antimttr (Tue, 03 Mar 2020 20:36:20 GMT):
so that makes it so you dont have to use the -m flag when you call fabric-ca-client ?
ownspies (Tue, 03 Mar 2020 20:36:30 GMT):
I *think* that is what I was doing
Antimttr (Tue, 03 Mar 2020 20:38:46 GMT):
did you already know k8 before you started your hlf project?
Antimttr (Tue, 03 Mar 2020 20:39:05 GMT):
im wondering if i should just bite the bullet and use k8 instead of docker-compose
ownspies (Tue, 03 Mar 2020 20:40:16 GMT):
no, learned it as I went
ownspies (Tue, 03 Mar 2020 20:40:22 GMT):
K8S and Helm charts
ownspies (Tue, 03 Mar 2020 20:40:34 GMT):
I didn't learn the install part, I'm using AWS EKS
ownspies (Tue, 03 Mar 2020 20:40:39 GMT):
but could easily be GCE
ownspies (Tue, 03 Mar 2020 20:40:57 GMT):
nice thing about K8S is portability (as much as anything can be portable)

I cleared all docker images prior and tried changing the capability version in confitx.yaml but still error, the orderer container closes immediately
theDweeb (Wed, 04 Mar 2020 15:24:52 GMT):
nvm I fixed it. The the script that pulls the images must be incorrect, I used the latest curl command from readingthedocs and it worked.

fabric-gateway - is this still the only way to override the max message size?
```
p.put("grpc.NettyChannelBuilderOption.maxInboundMessageSize", grpcMaxInboundMessageSize);
p.put("grpc.NettyChannelBuilderOption_maxInboundMessageSize", grpcMaxInboundMessageSize);
```
Antimttr (Wed, 04 Mar 2020 19:06:16 GMT):
there is one option about max message size in the orderer section of the configtx.yaml
Antimttr (Wed, 04 Mar 2020 19:06:22 GMT):
so it would be a per channel option
Antimttr (Wed, 04 Mar 2020 19:06:46 GMT):
```
# Batch Size: Controls the number of messages batched into a block
BatchSize:
# Max Message Count: The maximum number of messages to permit in a batch
MaxMessageCount: 10
# Absolute Max Bytes: The absolute maximum number of bytes allowed for
# the serialized messages in a batch.
AbsoluteMaxBytes: 98 MB
# Preferred Max Bytes: The preferred maximum number of bytes allowed for

aatkddny (Thu, 05 Mar 2020 00:27:30 GMT):

Antimttr (Thu, 05 Mar 2020 01:58:14 GMT):
ahh so its an sdk level setting
Antimttr (Thu, 05 Mar 2020 01:58:16 GMT):
gotcha
bestbeforetoday (Thu, 05 Mar 2020 09:58:04 GMT):
I guess your peers are running in local Docker containers so your client will need to resolve them as _localhost_ rather than _peer1.org2.example.com_. If you set an environment variable `org.hyperledger.fabric.sdk.service_discovery.as_localhost` to `true`, this should coerce the SDK to resolve discovered nodes to localhost instead of using their advertised host name
mauricio (Thu, 05 Mar 2020 11:41:23 GMT):
Hi, @bestbeforetoday I already tried that but I'm getting the same error :/
I'm setting `ORG_HYPERLEDGER_FABRIC_SDK_SERVICE_DISCOVERY_AS_LOCALHOST=true` in my ~/.zshrc
mauricio (Thu, 05 Mar 2020 12:48:48 GMT):
I set the `peer1.org2.example.com` to 127.0.0.1 in the `/etc/hosts` and it works, thanks @bestbeforetoday
mauricio (Thu, 05 Mar 2020 12:50:12 GMT):
Do you know why my querys are taking so long in executing, around 11seconds, and the querys are caching and aren't retrieving the last information.

bestbeforetoday (Thu, 05 Mar 2020 13:08:49 GMT):
Glad you got that sorted. The environment variable dictates how it SDK handles nodes obtained through service discovery. I guess you had your peers listed in your connection profile, in which case you just need to make sure they resolve, and adding those entries to /etc/hosts is the way I do it
bestbeforetoday (Thu, 05 Mar 2020 13:09:19 GMT):
I don't know what would be causing your queries to be so slow, or why they would be cached. The SDK doesn't cache any results
dan13 (Thu, 05 Mar 2020 13:59:52 GMT):
Have you confirmed that the block has committed to the peer you are querying?
aatkddny (Thu, 05 Mar 2020 18:07:09 GMT):
ok so after a detour through fabric-orderer i'm back to the sdk.
or more accurately fabric-gateway.
it used to be that you could set an override in the properties for each of the peers and orderers to allow a message larger than the default max for netty (which the sdk delegates to for grpc) to be used.
we used it successfully for quite some time.
then we switched to fabric-gateway.
we create a network config with the same parameters (and can see it changes the netty default) but we still can't do anything with a message that *grows* bigger than the default max as a result of the chaincode execution.
so my question is simple - has anyone managed to put a message larger than the 4M (or so) default limit?
if so, how?
Antimttr (Thu, 05 Mar 2020 21:32:57 GMT):
I'm trying to instantiate chaincode on mychannel using the Java sdk, and im calling channel.sendInstantiationProposal(), to my set of peers, I get all proposal responses back failed, however they dont have anything in their message so im kind of at a loss as to how to trouble shoot this, has anyone ever gotten back failed proposal responses with no message?
Antimttr (Thu, 05 Mar 2020 21:54:10 GMT):
so i just enumerated all the messages not just the first one
Antimttr (Thu, 05 Mar 2020 21:54:33 GMT):
now the message for sending the transaction to my first peer on org 1 is still empty, but all the other peers (i sent out 3 proposals) failed due to timeout

Hello, I have a question please, I want to select a random ordered to send a normal e transaction, I configured a service discovery with one peer with a discovery rule. I had one ordered in my config file and I add it to the channel.... but after adding the discovery, I tried to delete the order and I saw that it doesn't cause problems and the transaction passed normally, and while checking logs, the order of my hyperledger is known.. so I want to know is this a normal behaviour and when I add many orderers, did it know them all and the transaction is sent normally?

Any fabric-gateway guys here? I am trying version 2.0 of gateway, found a bit different with 1.4. There is no method to get cert and key in the Identity got from wallet. There was Identity.getCertificates() and Identity.getPrivateKey() in the old version. How can I do now? Thanks.
bestbeforetoday (Wed, 01 Apr 2020 08:03:35 GMT):
Although the Wallet returns an Identity object, it will actually be an X509Identity, which has methods to get the Certificate and PrivateKey objects for the identity: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/X509Identity.html
bestbeforetoday (Wed, 01 Apr 2020 08:05:53 GMT):
Also look at the Identities class for utility methods for translating Certificate and PrivateKey objects to/from PEM strings: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Identities.html
bestbeforetoday (Wed, 01 Apr 2020 08:09:10 GMT):
The reason the Wallet returns the base Identity type is we hope to get other identity types supported (for example HSM-managed identities) that do not necessarily have a Certificate and PrivateKey
bestbeforetoday (Wed, 01 Apr 2020 08:12:24 GMT):
Would it be helpful to avoid your client code having to cast the Identity if the wallet had an overload of the get method something like:

```
T get(String label, Class type)
```
bestbeforetoday (Wed, 01 Apr 2020 08:17:20 GMT):
Then you would call: ```
X509Identity identity = wallet.get(“username”, X509Identity.class);
```
qubing (Wed, 01 Apr 2020 09:51:32 GMT):
I got it. Under your strong support, I successfully upgraded my application program to new version. Thank you so much. Because the main difference between 1.4 and 2.0 in SDK is wallet management, I suggest to provive more samples or test case around it. It will be helpful for developers.:beers:

I just started using fabric-gateway-java coming from using the nodejs sdk. First thing I noticed is that the CLI container is generating everything instead of having the binaries downloaded on local machine (i.e. like test-network). Which approach is best practices? Is the CLI just for testing?

Hi, I'm trying to understand if it possible to get certificate of an already enrolled user from Fabric CA through the SDK. The idea is to avoid storing all certificates on the server which is running the sdk and get the user certificate from the CA when the user needs to call a chaincode. It is possible?

you can use `createTransaction' instead of 'submitTransaction'. After creating a transaction set the endorsing peers and then do transaction.submit(..args)

bestbeforetoday (Tue, 21 Apr 2020 08:20:02 GMT):
Yes, you can (and absolutely should!) use the same Gateway, Network or Contract instances for multiple requests from the same client identity
bestbeforetoday (Tue, 21 Apr 2020 08:29:27 GMT):
The peers used to evaluate (rather than submit) transactions is dictated by the query handler. The default will continue to use the first responsive peer it finds in the same organisation as the client identity. There is another default query handler implementation that will round-robin requests across all peers in the same organization as the client identity. You can also write your own query handler implementation if you want specific behaviour or to use specific peers. See here for details: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Gateway.Builder.html#queryHandler-org.hyperledger.fabric.gateway.spi.QueryHandlerFactory-

Hey Guys,
I am facing issues with API connecting with multiple orderers for queries and transactions.
I have three orderers for our network. All the three orderers are on the same machine so we're using port forwarding for orderer1(8050:7050) and orderer2(9050:7050)
These are the orderer defaults in configtx.yml:
- Host: orderer0.example.com
Port: 7050
...
- Host: orderer1.example.com
Port: 7050
...
- Host: orderer2.example.com
Port: 7050
...
These are the orderer details in connection-profile.jon:
"orderers": {
"orderer0.example.com": {
"url": "grpcs://localhost:7050",
...
"grpcOptions": {
"hostnameOverride": "orderer0.example.com"

},
"orderer2.example.com": {
"url": "grpcs://localhost:9050",
...
"grpcOptions": {
"hostnameOverride": "orderer2.example.com"
}
},
},
I am using NodeJS fabric gateway to create and do transactions on channels.
When the gateway configuration parameter "asLocalhost" is set to true all the queries and transactions are happening through orderer0. This becomes an issue if orderer0 goes down as the gateway doesn't automatically connect to the remaining orderers.
When the gateway configuration parameter "asLocalhost" is set to false the gateway has the information for all the three orderers unlike when asLocalhost is set to true, but all the channel orderers point to 7050 port instead of their respective ports. It looks like the orderers are being retrieved from consortium. Since we need to connect to orderer1 and orderer2 at 8050 and 9050 ports respectively the API is unable to connect to them at 7050 port.

When the gateway configuration parameter "asLocalhost" is set to false the gateway has the information for all the three orderers unlike when asLocalhost is set to true, but all the channel orderers point to 7050 port instead of their respective ports. It looks like the orderers are being retrieved from consortium. Since we need to connect to orderer1 and orderer2 at 8050 and 9050 ports respectively the API is unable to connect to them at 7050 port.

@bestbeforetoday Hope you are doing good. I just got to know that administrative capabilities would be discontinued from 2.1 version for Node SDK. Is there a plan to deprecate for JAVA sdk as well? I am sure there would be a big reason for this. If you don't mind, could you please share the thought process for this decision.

The thinking across Fabric in general seems to be that administrative tasks should be performed using the admin command-line tools. Perhaps to ensure consistency with a single admin client implementation and to save re-implementing the same admin capability in all the language SDKs every time anything changes, which is quite a bit of work. When the internals of the Node SDK were re-written for v2.0 we didn't re-implement all the admin capability using the new internal structure. I don't know of any plan right now to remove the admin capability that is there in the Java SDK but I also don't currently expect it to get extended with any new admin features. I did hear some talk of chaincode lifecycle operations possibly being reimplemented in the Node SDK, either as an npm package (within the SDK repository) or as a sample (based on the _fabric-network_ API). I don't have any firm details or timescale for that work though

Can someone help me with a chaincode querying couchDb ?
When calling the CouchDB from a java chaincode for a rather not large data collection (150), the process of the result takes 50 seconds.
I can see that the ChaincodeInvocationTask.invoke got the response rather quick but when it is passed as a response that is taking a long time to process.
This class is created from the response, QueryResultsIteratorImpl in the InvocationStubImpl. Anyone had this when calling InvocationStubImplgetQueryResult

So will there be any way to automate this or to script a more complex scenario?
Adding (say) a half dozen orgs and 20 channels when you stand up a new environment is not a trivial task. And we stand up and tear down environments more than you'd think.
It's fairly easy to automate using the SDK - we've been doing it for quite some time. I shudder to think of the time sink to do the same actions manually through a CLI.
bestbeforetoday (Wed, 06 May 2020 10:08:27 GMT):
I would try also posting this question on the #fabric-java-chaincode channel
bestbeforetoday (Wed, 06 May 2020 10:19:30 GMT):
Set up, configuration and chaincode deployment can all be automated using the CLI commands, either using scripting or launching the CLI commands from code. The SDK integration tests do this. I appreciate that it's a change if you already have the automation in place using the SDK though. The relevant parts of the Java SDK build are:
- https://github.com/hyperledger/fabric-gateway-java/blob/master/src/test/fixtures/generate.sh
- https://github.com/hyperledger/fabric-gateway-java/blob/67864d8316201ac96286ae8e7afb696ef6483c3e/src/test/java/scenario/ScenarioSteps.java#L113

Hi, I'm running a multi-channel multi-contract application, where the contracts make cross-contract as well as cross-channel invocations. I'm getting a weird error in one of my intermediate transactions where the proposal fails with the error `The proposal responses have 2 inconsistent groups with 0 that are invalid.`. Clearly, this indicates that though each proposal response (from an endorsing peer each) is valid, the two responses are not identical.
The problem is: when I look at the contract container logs, both containers that simulated the transaction show a successful run, exactly what I would have expected them to. Then where could the inconsistency have risen from? How would I go about debugging this?
An even weirder thing: when I add another endorsing peer to the above contract while keeping the rest of the network exactly the same, I get a similar failure but in an earlier stage of my workflow for a different transaction on a different contract (one that succeeded in the earlier run.)
bestbeforetoday (Thu, 07 May 2020 19:00:26 GMT):
Best guess is either:
- The transaction function is non-deterministic so different peers may produce different read/write sets or return values
- The ledger state is not consistent between peers
You would need to dig into the proposal responses to see exactly what is different
Mms 11 (Thu, 07 May 2020 19:34:07 GMT):
Exactly what @bestbeforetoday mentioned. Usually I'm getting this when passing a collection and two or more peers return elements in different order or when your serialization mechanizm return elements in unordered manner.
Mms 11 (Thu, 07 May 2020 19:35:23 GMT):
For example, I created a Jackson based SerializationInferface that is used by the contract I need to specify the order of each property or make it return props in a given order (like alphabetic).
vramaiitkgp (Thu, 07 May 2020 20:46:45 GMT):
You both were exactly right, thanks! I'm calling `putState` on a JSON serialized to a string, and the serialization turns out to be non-deterministic. I found out only when I turned on debug-level logging for the sdk package.

Unless you are on an extremely old version of Fabric, I suspect you don't want to be using EventHub at all. These were superseded in the low-level SDK by the peer eventing service. Ideally use the event listening capabilities of the _fabric-gateway-java_ API, which are much easier to use for both realtime listening and event replay. Simply pass in a listener / callback function and events get delivered to you:
- Attach block (or transaction commit) listeners to a Network (analogous to a Channel): https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Network.html
- Attach contract listeners to a Contract to receive chaincode events: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Contract.html

Hi @bestbeforetoday ..I was trying to test the 2.1 version of fabric, using one endorser and orderer. I am getting around 10 Transaction per second. Is there I can do to increase the performance?
bestbeforetoday (Fri, 15 May 2020 16:37:17 GMT):
It's worth understanding the flow. On submit the client is:
1. Gathering endorsements from peers and sending the endorsed proposals to the orderer
2. Orderer gathers transactions until it is ready to cut a block and send it to the peers
3. Peers commit the transactions in the block and emit a block event
4. Client receives block events containing successful transaction events from some number of peers, then returns from the submit call
bestbeforetoday (Fri, 15 May 2020 16:39:53 GMT):
There are several points in the flow that can impact performance:
- Orderer typically waits for a sufficient number of transactions or a time period before cutting a block
- The number of commit events the submit waits for, and from which peers
- Whether the client waits at all for events
- The number of concurrent client invocations
bestbeforetoday (Fri, 15 May 2020 16:43:06 GMT):
If subsequent transactions don't rely on the ledger updates of previous transactions, you can probably gain a big chunk of performance by disabling the commit waiting. Set the commit handler on the gateway to be `NONE`: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Gateway.Builder.html#commitHandler-org.hyperledger.fabric.gateway.spi.CommitHandlerFactory-
bestbeforetoday (Fri, 15 May 2020 16:44:28 GMT):
A scenario where this might be appropriate is a batch process just adding new assets to the ledger. It doesn't affect any of the existing ledger content
bestbeforetoday (Fri, 15 May 2020 16:45:23 GMT):
Another approach might be running more client load in parallel. So multiple threads all submitting transactions
bestbeforetoday (Fri, 15 May 2020 16:47:25 GMT):
Since you only have a single peer, the commit handler type you pick (other than `NONE`) shouldn't affect your performance, but in a larger network then it might. It's a trade-off between performance and the consistency of ledger state you need for subsequent application work
bestbeforetoday (Fri, 15 May 2020 16:48:36 GMT):
If you're really maxing those things out then you might also want to look at the core Fabric configuration. So the wait time before the orderer cuts a block, and also the maximum number of transactions to include in a block
bestbeforetoday (Fri, 15 May 2020 16:50:24 GMT):
You probably want to get quite a lot of transactions in a single block for maximum throughput, but there's a balance to be had between block size and latency before transactions are included in a block and committed on peers
ShobhitSrivastava (Mon, 18 May 2020 06:38:09 GMT):
Thanks @bestbeforetoday for your detailed answer, I optimized java sdk a bit and reached around 125 TPS. I also updated the orderer configuration to decrease the latency of commitTime to be 1 second and number of messages to be 5.
ShobhitSrivastava (Mon, 18 May 2020 06:39:00 GMT):
Also can you confirm if I increase the number of ordering node, will the TPS increase?
ShobhitSrivastava (Mon, 18 May 2020 06:40:04 GMT):
I also set logs to FATAL in peer and orderer config file,
bestbeforetoday (Mon, 18 May 2020 10:15:07 GMT):
I would expect you to be able to get a higher throughput (TPS) with a larger number of messages per block. The optimum numbers are going to be dependent on your workload and performance requirements though
ShobhitSrivastava (Mon, 18 May 2020 10:16:53 GMT):
sure. I will change the configuration.

Hi @bestbeforetoday ..is there a way in fabric to get the exact time when a transaction reaches Orderer and comes out of the orderer ?
bestbeforetoday (Wed, 20 May 2020 08:16:22 GMT):
Just a heads up since a couple of people requested the changes included... v2.1.2 of _fabric-gateway-java_ has been released:

bestbeforetoday (Wed, 20 May 2020 08:27:48 GMT):
If the top of my head I can't think of anything (except perhaps inspecting logs on the orderer). Transaction events emitted after transactions are committed include a timestamp but I think this is the client timestamp when the transaction was created rather than anything to do with the orderer. Somebody else might have better information

If you are doing development and running a Fabric network in Docker containers on your local machine, the nodes in the network will likely have addresses such as _peer1.org1.example.org_, which won't resolve in DNS for a client application running on your local machine (outside of the Docker network). One solution is to add those node addresses to your machine's local _hosts_ file so that they are treated as the loopback (locoalhost) address for your machine, e.g. `127.0.0.1`. Another approach if using service discovery to set the environment variable `ORG_HYPERLEDGER_FABRIC_SDK_SERVICE_DISCOVERY_AS_LOCALHOST=true`, which tells the client to treat all the addresses received through service discovery as localhost

_fabric-gateway-java_ doesn't provide administrative capabilities. You would need to use the fabric-ca CLI, _fabric-sdk-java_ or something else to enroll with the CA. Once you get credentials back from enrollment then you can use _fabric-gateway-java_ to create an Identity object and either store that identity in a wallet or use it directly to connect the Gateway:

Hi, I'm interested in the feature for signing a transaction offline. I found this feature in node sdk but not in sdk java. Someone already created the jira issue(https://jira.hyperledger.org/browse/FABJ-445) regarding this. Is there any update for this or any plan in the future?
bestbeforetoday (Thu, 04 Jun 2020 08:36:18 GMT):
The signing is done by calling `CryptoSuite.sign(PrivateKey, byte[])`. Instead of setting the default CryptoSuite implementation on the HFClient, perhaps you could set your own CryptoSuite implementation that does signing by other means when `sign(PrivateKey, byte[])` is called on it. I think the User object will still need to have a dummy private key assigned to it to prevent some of the SDK code complaining it was missing, but this would be ignored as you are supplying your own signing implementation. Would that satisfy your requirement?
KyoungsunPark (Thu, 04 Jun 2020 10:21:36 GMT):
Thank you for your reply. :) Actually end users don't want to share their private key. They want to sign the transaction in user's device without sharing the private key. I need to pass unsigned proposal and unsigned transaction to end user then get signed proposal and transaction from the user. But as I know, signing is done by private key on user object when sendTransaction is executed so I cannot split the transaction process. How can I create the unsigned proposal(transaction) and send signed proposal to peers(orderers) step by step?

Would it be workable for your CryptoSuite implementation to pass the data to be signed to the client when CryptoSuite.sign() is invoked on it, and then wait for them to return the signed data to you before returning that from the call to CryptoSuite.sign() ?

KyoungsunPark (Fri, 05 Jun 2020 02:07:51 GMT):
Yes, you're right. It is possible to pass the data to sign by CryptoSuite.sign(PrivateKey, byte[]). I'm using Channel.queryByChaincode(QueryByChaincodeRequest queryByChaincodeRequest) when querying the chaincode. Instead of queryByChaincode, I sent the date to the client and return back signed data then tried to send signed proposal to peers. But sendProposalToPeers() is private so I could not send the data to peers. Is there any accessible function for sending proposal to peers? Similarly the function for sending transaction to orderers is not accessible. Signing by CryptoSuite.sign() is workable but it failed to send it peers and orderers using Channel class. Thanks.
bestbeforetoday (Fri, 05 Jun 2020 07:57:35 GMT):
Do you know why and at what point the signed proposal was rejected? Getting the signing correct is not trivial. I would suggest looking at the default CryptoSuite signing implementation: https://github.com/hyperledger/fabric-sdk-java/blob/a66d7080f99846a230a69eeedf115c68167bef86/src/main/java/org/hyperledger/fabric/sdk/security/CryptoPrimitives.java#L756
KyoungsunPark (Mon, 08 Jun 2020 02:20:18 GMT):
Hmm.. signing is no problem as CryptoSuite.sign that you suggested. My problem is that signed proposal cannot be sent to peer by channel.sendProposalToPeers because this is the private function. In node sdk, Channel.sendSignedProposal() is supported and you can find it on https://github.com/hyperledger/fabric-sdk-node/blob/0d24cec10f7a3e0153fcf3f0158a89c5eaa0cfab/docs/tutorials/sign-transaction-offline.md. I need the function to send signed proposal to peers. Thanks.
bestbeforetoday (Mon, 08 Jun 2020 07:58:08 GMT):
I don't think you're understanding what I am suggesting, which is that you:
1. Set your own CryptoSuite implementation on HFClient, with a CryptoSuite.sign() implementation that does your offline signing.
2. Call Channel.sendTransactionProposal() as normal to send the transaction proposal, which will invoke your CryptoSuite.sign() implementation at the appropriate point.
So you use continue to use Channel.sendTransactionProposal() but it uses your signing implementation.

hi may I ask fabric-gateway-java question here?
SamYuan1990 (Tue, 09 Jun 2020 10:23:11 GMT):
Recently I am coding fabric client application via java.
I am noticed that there seems no connection pool feature provided by either fabric-gateway-java or fabric-sdk-java.
As application developer point of view, I suppose there should be a connection pool, as a sub-system responsible for connecting to fabric.
1) Performance. As it's well known that connection pool is good for performance.
2) Maintainability. Code will be easier to maintain than if each component connected to the fabric itself.
3) Diagnostics. It becomes easier to diagnose and analyze fabric connection usage.
Is there any plan to have a connection pool feature for fabric-gateway-java?
bestbeforetoday (Tue, 09 Jun 2020 10:47:23 GMT):
You should definitely use a Gateway for multiple requests by the same client identity. There is significant overhead associated with connecting to the network so you don't want to be connecting and closing on every request. On the other hand, if you are not going to make any further requests with that client identity, either for the lifetime of the client application or for some significant period of time, it is beneficial to close the connection rather than leave them hanging open. It's difficult for any caching scheme implemented in the SDK to know what your application is going to do in the future and so it's difficult for any caching scheme in the SDK to behave appropriately for your application. It's not very difficult for your application to keep hold of a Gateway instance and reuse it for subsequent requests if it knows that will be required.
bestbeforetoday (Tue, 09 Jun 2020 10:48:04 GMT):
So right now, I don't have any plans to try to implement a caching scheme within the SDK
bestbeforetoday (Tue, 09 Jun 2020 10:53:50 GMT):
It might be possible to optimise the number of gRPC connections created by client applications using the Gateway, by doing some sharing of the underlying connections between Gateway instances. I don't know of any near-term plan to implement those optimisations in the current SDK versions
SamYuan1990 (Tue, 09 Jun 2020 11:10:22 GMT):
Well, I tested and understand that currently to use gateway for multiple requests as your said above.
To have a high thoughput for client application in multiple request scenario.
I received output for gateway query via stringbuffer. with query A or query B, but some error happens as query A with result 210 and query B with result 90.
What I expected, or questioned is that is there any way for safety multiple thread?
I hope by a "pooled feature" can implments that kind of safety multiple thread.
SamYuan1990 (Tue, 09 Jun 2020 11:12:13 GMT):

The API should be thread safe. If you find any cases where fabric-gateway-java doesn't behave in a thread safe manner, please raise a bug in Jira. However, the Fabric blockchain network is a distributed ledger and so you should get eventual consistency but not the same kind of consistency you might expect from a centralised system such as a sing instance database. Different peers in the network may be at different block heights and so their world state may be different at any given point in time. The result you get from a query depends on the state of whichever peer the query executes on. The commit and query strategies provided by the Gateway are intended to mitigate this by allowing you to wait for submitted transactions to be committed on peers before subsequently going on to evaluate transactions (query) those peers

I think the value returned should be a transaction event if you have chosen to wait for commit the transaction to commit on peers and it completes successfully. If you have set NOfEvents.nofNoEvents (so not waiting for commit on peers) then it will just return null after a successful send to the orderer

Hi guys, could anyone help with batch uploads?
I'm trying to upload around 200-400 records to the blockchain via a java chaincode.
This process takes about 3 -4 minutes which is taking a bit. While uploading around 40-50 records, that takes 5-8 seconds. I identified that such a long time is because of the proposal time response.
Is this a normal speed or is there a way using configuration to speed it up? Is there any „Bulk import features” that I could use ?

Just so I understand what you are doing... do you mean 200 - 400 records in a single transaction, or do you submit a separate transaction for each record? I think in general (and within message size limits) it's more performant to batch multiple records up into a single transaction and do all the putState operations for those records in a single transaction. Another thing to seriously consider is whether these records (or transactions) are independent of each other. If they are independent (so don't touch the same ledger entries) then you can probably get much better performance by executing them in parallel using a multi-threaded client application. Submitting transactions sequentially likely means you'll get one per block and all the latency involved in the block cutting whereas in parallel you will likely get many transactions per block. Another factor (usually determined by whether your transactions and independent or not) is whether you need to wait for transactions to be committed by peers for submitting subsequent transactions. You will get the highest throughput if you don't need to wait for the commits (or possibly optimise by waiting for the commits asynchronously)

The comparative performance numbers between these two pages might help. They are using a Node.js client but I would expect the performance trends to be consistent.

Thanks @bestbeforetoday, I'm pushing these messages all in one transaction. The db response time is quick but for some reason the time the client waits for the proposal transaction confirmation to be returned accepted or not takes long minutes (I'm not sure what is the reason as I didn't check detailed debug logs yet). I will have a look at the examples you have send - thx!

Hi, yesterday I finally moved to fabric gateway 2.1.3 and I have some question about the transaction process. @bestbeforetoday
So, as I understood, when I call `submitTransaction()` the returned byte array is the payload returned by the chaincode.. But, is the transaction successfully committed to the ledger or the call return as the transaction is submitted to the orderer?
Second question: how can I get the transaction Id of a submitted transaction? I need to attach a listener right? But what type? And there is a code example of this?

bestbeforetoday (Fri, 26 Jun 2020 08:10:09 GMT):
By default `submitTransaction()` will return only after seeing successful commit events from all your organisation peers. You can select alternative default behaviour by setting a different commit handler when connecting the Gateway, or provide your own custom implementation if none of the default options suit you:
- https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Gateway.Builder.html#commitHandler-org.hyperledger.fabric.gateway.spi.CommitHandlerFactory-
If you want different behaviour for different transactions then you can override the default commit handling behaviour on a per-transaction bases:
- https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Transaction.html#setCommitHandler-org.hyperledger.fabric.gateway.spi.CommitHandlerFactory-
In some cases you might want to get the transaction result immediately after the transaction is successfully sent to the orderer but still listen asynchronously (or in another process) for that transaction to commit on peers. You can achieve this by:
1. Use the `NONE` commit handler: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/DefaultCommitHandlers.html#NONE
2. Get the transaction ID prior to submitting the transactions: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Transaction.html#getTransactionId--
3. Also before submitting the transaction (so you don't miss the commit), add a commit listener to the Network to observe commit events for that transaction: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Network.html#addCommitListener-org.hyperledger.fabric.gateway.spi.CommitListener-java.util.Collection-java.lang.String-
There is an example of a commit listener being used in a custom commit handler implementation here: https://github.com/hyperledger/fabric-gateway-java/blob/master/src/test/java/org/hyperledger/fabric/gateway/sample/SampleCommitHandler.java
bestbeforetoday (Fri, 26 Jun 2020 08:32:47 GMT):
Unless you are really pushing the boundaries of transaction throughput or have very strict responsiveness requirements, probably keeping your application code simple and just letting `submit()` deal with any commit event handling you need is a good option
Bolzo 1 (Fri, 26 Jun 2020 08:43:48 GMT):

You can add a block listener with replay starting at the first block: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Network.html#addBlockListener-long-java.util.function.Consumer-
bestbeforetoday (Tue, 30 Jun 2020 12:43:01 GMT):
You can access all the transaction events within the block event pretty easily
bestbeforetoday (Tue, 30 Jun 2020 13:20:15 GMT):
If you are replaying a large number of blocks then you might consider using a checkpointer to maintain the current block number the replay has reached in case the client fails and needs to resume from the last processed block: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Network.html#addBlockListener-org.hyperledger.fabric.gateway.spi.Checkpointer-java.util.function.Consumer-

So I had a few minutes to look into this.
I’m definitely not exceeding the volumes that the report is saying (going with around 150-300 records) which is a very small value in contrast to what it was presented in the report.
Is there some configurations that would be causing such long executions ? With around 220 records I’m reaching blockchain timeout connection limits
(2020-07-01 17:45:04.380 UTC [endorser] SimulateProposal -> ERRO 195 failed to invoke chaincode poc-services, error: timeout expired while executing transaction

c0deh0use (Thu, 02 Jul 2020 09:44:17 GMT):
Can anyone help with tweaking the performance of the process of uploading a number of records to the blockchain?
I have around 300 records to upload, nothing complex. The TransactionProposal takes so long it is getting timeout by the blockchain
I have been trying to change both the BatchTimeout - set to 10s and BatchSize.MaxMessageCount to 500, but nothing helped with the proposal times. It takes so long that there always is a timeout on the blockchain side.
I’m doing one putState per record, as I couldn’t find a putStates method, can this be the problem ?
I'm running on HLF 2.1.1, with two orgs, one raft orderer.
bestbeforetoday (Thu, 02 Jul 2020 19:25:23 GMT):
It sounds to me like you need some instrumentation (or at least analysis of timestamps in existing logs) to identify exactly where the time is being spent. It's difficult to know what the problem might be without knowing which part of the flow is taking all the time
bestbeforetoday (Thu, 02 Jul 2020 19:30:28 GMT):
One thing to experiment with might be to run a single batch transaction invocation to see what the latency is like. If a single transaction invocation performs well and you are running many transaction invocations in parallel then it might be that something is bottlenecking under load and you start to see failures. If so, it might be you can identify and work to remove that bottleneck, or it might be a case of tuning the rate of transactions to get optimum performance

I would recommend using the latest 1.4.x release of the Node SDK for 1.4.x releases of Fabric. The patch versions of the SDK and Fabric are not aligned; just the major/minor numbers. Also... the #fabric-sdk-node channel is a better place for Node SDK questions :)
bestbeforetoday (Tue, 14 Jul 2020 09:13:03 GMT):
The submit will use whatever commit handling behaviour is configured; by default the one specified when connecting the gateway (which itself defaults to MSPID_SCOPE_ALLFORTX). If you don't want the submit to block waiting for commits because you are doing your own listening for commits then use the NONE commit handler. If you want all transaction submits to behave this way by default, set this on the GatewayBuilder when connecting the Gateway. If you just want specific transaction submits to not wait for commits, set the NONE commit handler explicitly on those Transaction objects before calling submit:
- https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Transaction.html#setCommitHandler-org.hyperledger.fabric.gateway.spi.CommitHandlerFactory-
- https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/DefaultCommitHandlers.html#NONE
bestbeforetoday (Tue, 14 Jul 2020 09:55:32 GMT):
From very vague memory... there is some unit and integration testing of Idemix done in the Azure pipelines build; just not that one very long unit test piece since it takes so long to run in the Azure pipelines environment that the builds fail with timeouts. The test drives something like 2500 Idemix operations with many operations running in parallel, I presume to try to flush out any concurrency issues. If you're changing the Idemix code then it would be a good idea to set the appropriate environment variable to enable that test when running tests locally but it's way too long running to be a regularly run unit test

Hi, Q: We have a fabric setup where we deploy Go chaincode from source, now i notice that in the SDK the folder "src" is a hardcoded prefix for chaincodeSource location I give of the Go code. The go code I work with doesn't conform to this structure. So i was wondering why the decision was made to put the prefix in it?
(Yes, I know the method is called fromSource :wink: )
This is where the prefix, or to be perfectly correct insertion is added:
https://github.com/hyperledger/fabric-sdk-java/blob/032aa59356575f2d6d2210983c755b5acd0fca38/src/main/java/org/hyperledger/fabric/sdk/LifecycleChaincodePackage.java#L255
bestbeforetoday (Tue, 21 Jul 2020 18:03:16 GMT):
I don't know why it was conceived this way. At first glance, this doesn't look ideal to me. Possibly it was due to limitations of the structure expected on the server side prior to Go modules. I've raised this Jira to capture the request for more flexibility: https://jira.hyperledger.org/browse/FABJ-529

Hello, I'm trying to measure the throughput of a network that I created using the fabcar chaincode. I have started from the example java application in the fabric-samples repository (https://github.com/hyperledger/fabric-samples/blob/master/fabcar/java/src/main/java/org/example/ClientApp.java) and tried to generate transactions and add commit event listeners to check if the transactions are commited or not. However, all the examples that are present in the documentation require a transaction ID which I cannot obtain. What is the proper way to listen to a commit event using the java gateway?
bestbeforetoday (Wed, 22 Jul 2020 13:02:56 GMT):
Transaction.submit() already waits for commit events before returning (assuming you haven't set the commit handler to `NONE`)
NickName (Thu, 23 Jul 2020 06:35:44 GMT):

By default, contract.submitTransaction() will wait for until a submitted transaction is committed on peers before returning. So with one single-threaded client you will get one transaction per block and you can expect transaction rate to be slow. One approach to driving higher load is to run multiple concurrent clients (or client threads). Another approach is to not wait for transactions to be committed on the submit, which you can achieve by setting the `NONE` commit handler (either as the default when connecting the Gateway or on a per-transaction basis). Just be aware that any subsequent queries or transactions will not see ledger changes resulting from earlier transactions until those earlier transactions are committed

That's not an error I recall seeing before so I really don't know what the problem is.

bestbeforetoday (Wed, 05 Aug 2020 16:50:54 GMT):
If it is the second issue then you might need to import the CA certificate into your client's trust store, either programmatically or using the keytool utility. I'm not an expert in this area though

My interpretation of the documentation would be that it returns the point in time at which the key was modified to have the value specified in that KeyModification instance.

bestbeforetoday (Thu, 06 Aug 2020 10:42:25 GMT):
I'd guess that modification time is actually the timestamp of the transaction that updated the key, since different peers will commit to their local copies of the ledger at different times
ongchinkai (Thu, 06 Aug 2020 10:44:49 GMT):
So in the context of getting the history of the key via stub.getHistoryForKey(...), the last action would be committing the block, and the timestamp would be for that action, I suppose?

inconclusive because they don't say anything that points to an issue anywhere.
the peers still run transactions on other channels just fine - it's only when we try to upgrade chaincode that it's an issue. (and the chaincode is at something like V2.63 in increments of 0.01 so it's nothing new here).

If the logs don't point to an obvious issue, it might also be useful to know whether the same chaincode upgrade works using the CLI commands, to try to isolate whether the issue is client (SDK) side or server-side
aatkddny (Mon, 10 Aug 2020 00:12:06 GMT):
As an fyi:
We don't use the CLI. There's too many channels to look after so it's all been automated through the SDK.
I am in no hurry at all to move to the version where that support has been dropped...

Whisper it but the API to deploy chaincode is still there in fabric-sdk-java v2.2. It was only the v2 Node SDK where this got lost when all the internals were reworked for v2. There is a community proposal to contribute a Node admin package for v2 (raised on last week's contributor meeting)
aatkddny (Tue, 11 Aug 2020 18:54:17 GMT):
What about all the other stuff?
We stand up a network soup to nuts using the APIs.
Creating channels, adding anchors, installing and instantiating chaincodes, the lot. With an egg on top.

In the Node.js sample, when you run `node query` you are running a client application contained in the `query.js` file. From memory, that client application just runs a query and prints the results
bestbeforetoday (Wed, 12 Aug 2020 15:43:53 GMT):
There isn't an exactly equivalent sample Java application. Instead there is a sample application that does several pieces of work: queries and transactions
bestbeforetoday (Wed, 12 Aug 2020 15:44:55 GMT):
The Java/Maven equivalent to the `node fileName` command to launch the sample client application is the Maven command-line above
bestbeforetoday (Wed, 12 Aug 2020 15:46:12 GMT):
The samples are just examples of how to code a client application
bestbeforetoday (Wed, 12 Aug 2020 15:56:25 GMT):
If you want a command-line utility that can be used to submit or evaluate (i.e. query) arbitrary transactions then there are the `peer chaincode invoke` and `peer chaincode query` commands: https://hyperledger-fabric.readthedocs.io/en/latest/commands/peerchaincode.html

Mornings to the community . Which is the best way to store identity secret so i can use it afterwords ?
pkirkinezis (Tue, 18 Aug 2020 07:01:13 GMT):
For example would it be a best practice to create table on the database and save userId , certificate, private key (string) , hashed identity secret ?
pkirkinezis (Tue, 18 Aug 2020 07:02:04 GMT):
i mean the enrollment secret ..
bestbeforetoday (Tue, 18 Aug 2020 09:50:16 GMT):
If you have the certificate and private key you don't need the enrolment secret. It is just used to obtain the certificate from the CA. Best practice is probably for the CA to be configured to only allow enrollment to happen only once. That way, if you try to retrieve your certificate using enrollment and it fails, you know somebody else has obtained your enrollment secret and retrieved your certificate before you, so the identity has been compromised. It also prevents somebody from discovering your secret after you have retrieved your certificate and grabbing it from the CA after you, also compromising the identity.
pkirkinezis (Tue, 18 Aug 2020 10:02:59 GMT):
Thanks for you reply . How i can store private key on a database ? Because i dont want to store a wallet neather haveing keyfile to a filesystem path and retrieve them .
bestbeforetoday (Tue, 18 Aug 2020 10:04:51 GMT):
There is a CouchDB wallet store implementation if you want to use a Wallet to store to CouchDB: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Wallets.html#newCouchDBWallet-java.net.URL-java.lang.String-
pkirkinezis (Tue, 18 Aug 2020 10:05:32 GMT):
My concept is to use a Maria DB database(already exists on main app) in which every API will query to get the certs or credentials needed to enroll a user and execute query
bestbeforetoday (Tue, 18 Aug 2020 10:07:38 GMT):
Other alternatives are to:
1. Write your own WalletStore implementation to store at a location of your choosing; or
2. (If you don't want to use the wallet data format) you can just store the certificate and private key PEM from your Identity however you want, the create an Identity object using those credentials when you need to connect.
You can connect the Gateway using just an Identity and no Wallet: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Gateway.Builder.html#identity-org.hyperledger.fabric.gateway.Identity-
There are some helper function for converting certificates and private keys in the Identities class: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Identities.html

pkirkinezis (Tue, 18 Aug 2020 10:12:07 GMT):
My registration process is the bellow :
RegistrationRequest registrationRequest = new RegistrationRequest(username);
registrationRequest.setAffiliation(env.getProperty("affiliation"));
registrationRequest.setEnrollmentID(username);
registrationRequest.setSecret(secret);
String eSecret = caClient.register(registrationRequest, adminUserContext);
enrollment = caClient.enroll(username, eSecret);
final PrivateKey privateKey = enrollment.getKey();
pkirkinezis (Tue, 18 Aug 2020 10:13:09 GMT):
After the registration I enroll a user and call gateway builder to execute queries
pkirkinezis (Tue, 18 Aug 2020 10:13:09 GMT):
After the registration is success for every api call I enroll a user and call gateway builder to execute queries
pkirkinezis (Tue, 18 Aug 2020 10:20:02 GMT):
After enrollment with secret and userid i create a Enrolement object that then used to create a identity like bellow
pkirkinezis (Tue, 18 Aug 2020 10:20:03 GMT):
X509Identity userIdentity = newX509Identity(env.getProperty("mspid"), Identities.readX509Certificate(enrollment.getCert()), enrollment.getKey());
pkirkinezis (Tue, 18 Aug 2020 10:21:45 GMT):
So i can save Cert as string to database , but how I can save privatekey as string to database because toString() creates the string with curves X,Y.
bestbeforetoday (Tue, 18 Aug 2020 10:22:48 GMT):
It might be simpler to call the method to create directly from an enrollment: `X509Identity userIdentity = Identities.newX509Identity("mspId", enrollment);`
bestbeforetoday (Tue, 18 Aug 2020 10:23:55 GMT):
There are also `Identities.toPemString()` methods that will convert both Certificate and PrivateKey objects to PEM strings
bestbeforetoday (Tue, 18 Aug 2020 10:25:25 GMT):
And you can read those PEM strings back in using the `readX509Certificate()` and `readPrivateKey()` methods on Identities
bestbeforetoday (Tue, 18 Aug 2020 10:25:30 GMT):

Do you know how long the chaincode install operation is typically taking? I am wondering if the operation is sometimes taking longer than the default proposal wait timeout. In which case you could set a larger number on your request object

i cant upgrade at the moment. would you have any other pointers?
danilofaria (Tue, 18 Aug 2020 10:51:52 GMT):
it usually takes around 20 seconds. but sometimes it just takes forever and times out
bestbeforetoday (Tue, 18 Aug 2020 10:51:53 GMT):
I actually thought the default timeout was 120 seconds rather than the 60 seconds that you are seeing. Maybe that changed at some point though
danilofaria (Tue, 18 Aug 2020 10:54:27 GMT):
i older versions this step was a lot faster and never timed out
danilofaria (Tue, 18 Aug 2020 10:54:27 GMT):
in older versions this step was a lot faster and never timed out
bestbeforetoday (Tue, 18 Aug 2020 10:55:04 GMT):
It might also be worth checking the peer logs so see if the chaincode install is running successfully there
danilofaria (Tue, 18 Aug 2020 10:55:40 GMT):
sometimes this bit shows up:
```
peer0.org1.example.com_1 | 2020-08-12 17:08:18.657 UTC [endorser] SimulateProposal -> ERRO 03d failed to invoke chaincode _lifecycle, error: timeout expired while executing transaction

```
danilofaria (Tue, 18 Aug 2020 10:57:09 GMT):
i also noticed that when this happens, retry attempts also fail
bestbeforetoday (Tue, 18 Aug 2020 11:08:12 GMT):
I think there is a configurable peer timeout you can set too. It might be `CORE_CHAINCODE_EXECUTETIMEOUT`, which you set as an environment variable on the peer Docker container. Something like: `CORE_CHAINCODE_EXECUTETIMEOUT=300s`
danilofaria (Tue, 18 Aug 2020 11:57:30 GMT):
is it common for that step to take that long?
bestbeforetoday (Tue, 18 Aug 2020 12:06:43 GMT):
From memory, the install step does a fair bit of work, like building a chaincode docker container, so it might take some time to download and assemble dependencies. I guess it is also possible there is an issue so it might be worth looking into more logs of what is going on in the `_lifecycle` chaincode

Hello guys, can you help suggest what the best practice is to query a specific peer with java sdk.
Nick (Mon, 24 Aug 2020 01:08:37 GMT):
With service discovery, it seems we lost the capability to limit the peer that sdk can see, which was done in connection profile in previous release.
bestbeforetoday (Tue, 25 Aug 2020 08:43:42 GMT):
You can provide your own plugin logic for picking the peer(s) used to evaluate queries by setting a query handler when connecting the Gateway: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Gateway.Builder.html#queryHandler-org.hyperledger.fabric.gateway.spi.QueryHandlerFactory-
I don't think there is a sample query handler with the Java SDK but the implementation should be pretty straightforward. The QueryHandlerFactory function you supply as part of the Gateway connect gets called with the Network when it is first required. It should pick the required peer(s) and then return a QueryHandler instance, which again is just a functional interface that will be invoked (with a Query object parameter) each time a transaction is evaluated. All you have to do in your code is tell the Query object which peer to use and return the results.

I think setting the environment variable as for _fabric-sdk-java_ will also toggle trace for _fabric-gateway-java_. Alternatively, since the SDKs use Log4J by default, you can include a `log4j.properties` configuration file in your classpath, similar to this: https://github.com/hyperledger/fabric-gateway-java/blob/master/src/test/resources/log4j.properties

@bestbeforetoday Thanks for the suggestion. Do you know where can I store this idemix identity so that I can reuse it again
bestbeforetoday (Thu, 27 Aug 2020 09:07:22 GMT):
That looks like an error message from the CA related to enrolment. It might be worth exploring why your application is re/enrolling identities to obtain certificates if it's been running for 1.5 months. You could also try the #fabric-ca channel to see if anyone has better information on why the CA might be generating that error

@bestbeforetoday I have actually successfully enrolled idemix user. I am not sure how to use the instance of idemix user. Can you navigate me to the documentation of java sdk and tell me how do I invoke a transaction using this idemix user?
bestbeforetoday (Thu, 27 Aug 2020 10:35:39 GMT):
You just set the Idemix user as the user context on your HFClient, the same as you would for a regular X509 identity
bestbeforetoday (Thu, 27 Aug 2020 10:43:30 GMT):
When it comes to storing the Idemix credentials, that's not something I've played with. Possibly you can just store your certificate and private key from the first step of enrollment with the CA and then use those credentials to make the call to `ca.idemixEnroll()` each time you restart your application
bestbeforetoday (Thu, 27 Aug 2020 10:52:31 GMT):
Yes, in as much as you likely need some admin credentials to register a new user identity. Once you've enrolled an identity and obtained their credentials (certificate and private key) you should probably keep those credentials and not re-enroll with the CA each time you want to get them

Within your code you have `caClient.enroll(registerar.getName(), registerar.getEnrollSecret())`, which gives you an `Enrollment` object. You are then attaching this to your admin `User` object with `adminUserContext.setEnrollment()`. You can get the `Enrollment` object back from your admin `User` object with `adminUserContext.getEnrollment()`. The `Enrollment` has the methods `getKey()` and `getCert()`, which are the credentials you should probaby be storing rather than re-enrolling with the CA every time you need to use them
bestbeforetoday (Thu, 27 Aug 2020 14:54:11 GMT):
`getCert()` gives you a String with is the X.509 certificate in PEM encoding. `getKey()` gives you a Java `PrivateKey` object. The _fabric-gateway-java_ API has some utility functions for translating between PrivateKey and X509Certificate objects to/from PEM encoded data: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Identities.html
bestbeforetoday (Thu, 27 Aug 2020 14:54:27 GMT):

[ ](https://chat.hyperledger.org/channel/fabric-sdk-java?msg=5vSnTBWhqFTAyNcoh) @bestbeforetoday I was trying to use java gateway. Do you know if we can use it with gateway?
bestbeforetoday (Thu, 27 Aug 2020 16:21:27 GMT):
The Gateway doesn't have explicit support for Idemix identities. _However_, I think you can probably get it to work by:
1. Build/connect a Gateway instance using an X509Identity (so containing the MSP ID, real certificate and private key)
2. Before using the Gateway for *anything* else, set your Idemix User context on the underlying HFClient using `gateway.getClient().setUserContext(yourIdemixUser)`
bestbeforetoday (Thu, 27 Aug 2020 16:29:59 GMT):
Ah, just remembered that `getClient()` isn't exposed on the Gateway interface to protect users from the implementation details that might change. It's a bit of a hack (and so isn't guaranteed to continue to work in the future) but you can cast the `Gateway` instance to a `GatewayImpl` instance to get access to the `getClient()` method. I'd be interested to hear if it works. If so, maybe proper Idemix support could be added to _fabric-gateway-java_ in the future relatively easily

Yeah to create adminUserContext is easy and then get enrolment . But this is not persistant i have to run caClient.enroll(registerar.getName(), registerar.getEnrollSecret()) in every register http request . I am not using sessions so i can't persist between request the adminUserContext . The best way is to user private key and pemcert to create enrollment

Something else . Enroll creates new keys everytime or it gives you the same keys ?
bestbeforetoday (Fri, 28 Aug 2020 10:24:55 GMT):
I think argument 2 is a serialized ChaincodeDeploymentSpec protobuf, and argument 3 is a serialized SignaturePolicyEnvelope protobuf: https://github.com/hyperledger/fabric/blob/ddffd901a677c0b284a9e0e0608f00290ebf4430/core/scc/lscc/lscc.go#L983
bestbeforetoday (Fri, 28 Aug 2020 10:25:02 GMT):
I would probably look to use the compiled protobuf Java implementation classes to work with them, e.g. `org.hyperledger.fabric.protos.peer.Chaincode.ChaincodeDeploymentSpec.parseFrom()`
bestbeforetoday (Fri, 28 Aug 2020 10:38:15 GMT):
Enrollment is about getting the CA to issue a signed certificate for your identity. You can supply an existing public/private key pair to the enrollment request. If you don't supply a public/private key pair then enrollment will generate a new key for you client-side every time, and then request a signed certificate for this key pair from the CA
pkirkinezis (Fri, 28 Aug 2020 10:39:30 GMT):
Thank for you reply i mean when i enroll with "username" and "secret" new keys are being generated ?
bestbeforetoday (Fri, 28 Aug 2020 10:40:37 GMT):
Yes
pkirkinezis (Fri, 28 Aug 2020 10:41:45 GMT):
So to get the same cert and private key and not generate new ones i have to "reenroll " and not "enroll" ?
bestbeforetoday (Fri, 28 Aug 2020 10:47:35 GMT):
You should just keep hold of your certificate and private key. Once you have them you don't need to talk to the CA anymore. The CA doesn't have your private key
pkirkinezis (Fri, 28 Aug 2020 10:50:10 GMT):

Hi, is it possible to change the Identity Enrollment Secret with HFCAClient object? It seems possible with CLI tool, but it's not clear with fabric-sdk-java
bestbeforetoday (Tue, 01 Sep 2020 09:53:30 GMT):
If you enroll using the HFCAClient in _fabric-sdk-java_ you will get back an Enrollment object, which contains an X.509 certificate and a private key. This can be turned into a Gateway Identity that can be stored in a wallet using `Identities.newX509Identity()`: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Identities.html#newX509Identity-java.lang.String-org.hyperledger.fabric.sdk.Enrollment-
bestbeforetoday (Tue, 01 Sep 2020 09:57:03 GMT):
If you already have an X.509 certificate and private key, perhaps from some other method of (or previous) enrollment, there are other methods on the `Identities` class to help you build a Gateway identity from `X509Certificate` and `PrivateKey` objects, and to convert to/from PEM-encoded forms on these objects: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Identities.html
bestbeforetoday (Tue, 01 Sep 2020 09:58:24 GMT):
There are methods on the `Wallets` class to allow you to create new or reference existing wallets backed by various types of storage: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Wallets.html
bestbeforetoday (Tue, 01 Sep 2020 09:59:38 GMT):
So after enrollment, you create an Identity and Wallet object and then just `put()` the Identity into the Wallet: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Wallet.html#put-java.lang.String-org.hyperledger.fabric.gateway.Identity-
bestbeforetoday (Tue, 01 Sep 2020 10:01:08 GMT):
If you have some other mechanism for storing and retrieving identity information, you have the option to connect a Gateway with a specific identity and not use a wallet at all: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Gateway.Builder.html#identity-org.hyperledger.fabric.gateway.Identity-
bestbeforetoday (Tue, 01 Sep 2020 10:03:34 GMT):

bestbeforetoday (Tue, 01 Sep 2020 10:13:00 GMT):
Not sure I 100% understand what you're trying to do but... you can specify the desired enrollment secret on the RegistrationRequest passed to `HFCAClient.register()`
YangMiranda (Tue, 01 Sep 2020 17:27:48 GMT):
Thanks fo answer the question.
Today i can register a user using some admin credentials and the method you told. I'm thinking in a case that user want to change his password used to enroll certs in a procedure implemented with SDK. It seems possible with CLI command, but it's not clear with SDK. (https://hyperledger-fabric-ca.readthedocs.io/en/release-1.4/users-guide.html?highlight=modify#modifying-an-identity)
bestbeforetoday (Wed, 02 Sep 2020 08:36:37 GMT):
I'm not sure what that CLI command is doing under the covers (might be worth asking on #fabric-ca, since I guess it might just be calling _register_ again) but I don't know of a modify operation provided by HFCAClient
bestbeforetoday (Wed, 02 Sep 2020 08:38:27 GMT):
Be wary of viewing this as changing the user's password though. The enrollment secret is just some arbitrary secret used to allow the user to be securely issued a certificate by the CA. Once they have the certificate (and corresponding private key), they should be storing and using that certificate and private key, not enrolling again. So the secret should generally be a one time thing

The tests look like they use a admin identity to register the user with the CA, then the user enrolls using their secret, then there is an idemixEnroll with the user's enrollment and Idemix MSP ID. That Idemix enrollment replaces the user's enrollment, but it still keeps the user's actual MSP ID. The Idemix MSP ID looks to only be used for idemixEnroll(): https://github.com/hyperledger/fabric-sdk-java/blob/655639204cefa9515cd27b8c4a9a4109da574b29/src/test/java/org/hyperledger/fabric/sdkintegration/End2endIdemixIT.java#L121

Can anyone explain the difference between channel.addPeer() and channel.joinPeer()?
bestbeforetoday (Thu, 10 Sep 2020 10:37:08 GMT):
I believe `addPeer()` is just adding it your client channel configuration, similar to including it in the connection profile. So just making your client aware of a peer that is already a member of the channel. `joinPeer()` is actually trying to make a new peer a member of a channel
ckong (Fri, 11 Sep 2020 02:40:41 GMT):
Since there seems to be a functional difference between the two, after I create a new Channel object and before I do channel.initialize(), which is the correct way to add peers - addPeer() or joinPeer()?
bestbeforetoday (Fri, 11 Sep 2020 07:39:56 GMT):
If the peer is already a member of the network and you just want to make your client aware of it then `addPeer()`. If the peer is not a member of a network and you want to join it as an additional node, `joinPeer()`

_fabric-gateway-java_ is focused enabling client applications to interact with the ledger through transactions and events. It doesn't provide administrative functions. Where practical, I would recommend using the `peer` CLI for administrative tasks
bestbeforetoday (Fri, 11 Sep 2020 12:04:37 GMT):
The lower level _fabric-sdk-java_ has administrative capability, and you are fine to use that, but how well it stays in step with future admin capabilities is likely to be determined by how much development effort the community is able to put into updating it

Not today, no. You would probably need to use `setEndorsingPeers()` on the Transaction to achieve a similar thing: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Transaction.html#setEndorsingPeers-java.util.Collection-
bestbeforetoday (Tue, 15 Sep 2020 12:15:32 GMT):
That does rely on you to identify the peers that need to be used for endorsement. If a collection is available to all peers in given organization(s) then you could use `network.getChannel().getPeersForOrganization()` to get candidate peers

Hi!
lupass93 (Thu, 17 Sep 2020 23:37:24 GMT):
I'm studying connection profile in hyperledger fabric. I would learn to define and make a connection profile for Java sdk for production network. But In the docs there is only guidelines for a test/development mode. I ask if you have a guidelines for define and make it for production mode. Thank you very much! 😊
bestbeforetoday (Fri, 18 Sep 2020 10:24:51 GMT):
There is no fundamental difference between a connection profile used to connect to a production or test/development network. The connection profile simply describes nodes (peers and orderers) to which the client can connect. My advice would be to configure your network to use discovery and minimise the nodes in the connection profile to peers the client should use to for initial connection and the discover the rest of the network nodes. That way you don't need to push new connection profiles out to all of your clients if the network topology changes
bestbeforetoday (Fri, 18 Sep 2020 10:26:55 GMT):
The only thing that springs to mind that is sometimes an issue in a production environment is idle gRPC connections getting more aggressively closed by ingress controllers or firewalls in the cloud deployment. You might want to specify gRPC connection properties like keep-alives, and the connection profile is a place this can be done
lupass93 (Fri, 18 Sep 2020 11:38:13 GMT):
Thank you very much for the answer.
About information like tlsCAcerts pem file, Is it safe to expose this information in connection profile file?

An X.509 certificate is essentially a public key and digital signature to prove the validity of that public key, so it should be safe to distribute
bestbeforetoday (Fri, 18 Sep 2020 15:45:51 GMT):
I haven't looked closely at that scenario but it would be worth looking at the logs for the chaincode Docker containers to see what happened in each organization, and perhaps also looking at the proposal responses attached to the ContractException thrown at the client end. From the error I'm guessing that the proposal was not endorsed by one of the organizations

ckong (Mon, 21 Sep 2020 03:30:48 GMT):
Regarding channel.sendTransactionProposal() vs channel.sendTransaction(), correct me if my understanding is wrong but the former only simulates the transaction in the peers with the chaincode, while the latter is where the actual transaction is processed. In that case, how necessary is it for a client calling channel.sendTransaction() to handle the results returned?
amolpednekar (Mon, 21 Sep 2020 06:04:48 GMT):
@bestbeforetoday Thanks for the pointers. So I noticed that chaincode logs on org2 are not getting updated, so its not executing.
Then I checked the proposal response on the client as you mentioned, and I see this
"CreateAsset cannot be performed: Error client from org Org1MSP is not authorized to read or write private data from an org Org2MSP peer"
But as per the collection details, both "memberOnlyRead": false, "memberOnlyWrite": false,
So it should work, no?
amolpednekar (Mon, 21 Sep 2020 06:29:22 GMT):
Update: Issue fixed
There was a function on the chaincode which checks whether clientMSP matches peerMSP, and this was returning and error response. Disabling this fixed it.
https://github.com/hyperledger/fabric-samples/blob/master/asset-transfer-private-data/chaincode-go/chaincode/asset_transfer.go#L561
@bestbeforetoday Can you tell how this function is different from what memberOnlyRead/memberOnlyWrite property in collections config does?

I strongly recommend you use the high-level 'gateway' API to submit transactions (https://github.com/hyperledger/fabric-gateway-java), much less code to write. It handles the gathering of endorsements, sending to ordering service, awaiting commit events, etc for you
ckong (Mon, 21 Sep 2020 10:50:51 GMT):
This is one of the things which I will have to look at soon, but for now I'm bound by constraints. How should the result from channel.sendTransaction() be handled, if at all?
bestbeforetoday (Tue, 22 Sep 2020 09:46:58 GMT):
If the CompletableFuture it returns completes exceptionally then something went wrong: either the send to the orderer failed or (if your transaction options say it should wait for commit events) then the required number of commits were not observed within a timeout period.
bestbeforetoday (Tue, 22 Sep 2020 09:49:05 GMT):
If it completes successfully then it successfully sent the transaction to the orderer and, if your transaction options say you wanted to wait for commit events, it also received the required number of events. If it waited for events then an event is returned
bestbeforetoday (Tue, 22 Sep 2020 09:50:25 GMT):
But as mentioned above, using the higher level Gateway API (which layers on top of the low-level API, so you can use them in combination) is preferred

bestbeforetoday (Thu, 24 Sep 2020 10:49:26 GMT):
Not right now, no. Probably the best you can do right now is, if you know the organizations needed for endorsement, get the peers for those organizations (from `network.getChannel()`) and set them as the endorsing peers on the Transaction: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Transaction.html#setEndorsingPeers-java.util.Collection-

My guess from the `SSLV3_ALERT_BAD_CERTIFICATE` is that your client didn't like the peer TLS certificate. Possibly because the signing CA certificate is not in the client JDKs trust store

There looks to be an option that can be added to a peer definition in a connection profile to tell it the CA certificate: https://github.com/hyperledger/fabric-gateway-java/blob/7133cf423dc07092d2ad0b0e418b88191e4e385a/src/test/java/org/hyperledger/fabric/gateway/connection-tls.json#L106

The Node.js sample _asset-transfer-private-data_ application sets the collections required for endorsement using the contract.addDiscoveryInterest() call available in the Node SDK: https://hyperledger.github.io/fabric-sdk-node/release-2.2/tutorial-discovery-fabric-network.html
bestbeforetoday (Thu, 01 Oct 2020 09:09:10 GMT):
There is not (yet) an equivalent in the Java SDK so the discovery-based endorsement is only considering the chaincode endorsement policy and not considering the required data collections

The workaround is to set the peers of the organizations that have access to the required data collections as the endorsing peers for the transaction
bestbeforetoday (Thu, 01 Oct 2020 09:32:57 GMT):
The status code just indicates to the SDK whether the proposal was successfully processed by the peer. It isn't an HTTP status code and isn't used to send application level information. What you get back is the payload or error message associated with a successful or unsuccessful transaction invocation

Hi to all is there a way to change password for user that are not registar? I am currently using the above logic for password uupdate
HFCAIdentity ide = caClient.newHFCAIdentity(user); // In newHFCAIdentity an EnrollmentID is passed
ide.setSecret(newPassword); // Here is the new password set
ide.update(userctx); // Here the user is updated.

Hello, can anyone tell if there is a way of skipping these steps each time you want to access the blockchain? 'Cause every HTTP Request I do, always takes around 16 mad seconds! It's inconceivable for any application performance
Path walletPath = Paths.get("wallet");
Wallet wallet = Wallets.newFileSystemWallet(walletPath);
// load a CCP
Path networkConfigPath = Paths.get("src", "crypto-material", "peerOrganizations", "org1.example.com", "connection-org1.json");
Gateway.Builder builder = Gateway.createBuilder();
builder.identity(wallet, "appUser").networkConfig(networkConfigPath).discovery(true);
try (Gateway gateway = builder.connect()) {
gateway.getNetwork("mychannel").getContract("basic", "AssetTransfer").submitTransaction("DeleteAsset", assetID);
return 1;
} catch (Exception e) {
}
bestbeforetoday (Wed, 07 Oct 2020 15:48:17 GMT):
If you are submitting subsequent requests with the same client identity, keep hold of the Gateway instance for that identity and use it for multiple requests instead of closing after every request
deployer21 (Thu, 08 Oct 2020 09:20:53 GMT):
Do you think that a queue + a thread implementation would do it or you have a better suggestion?

@bestbeforetoday can i only check the status of transaction by catching exceptions?
bestbeforetoday (Fri, 09 Oct 2020 08:22:15 GMT):
Typically we expect submitted transactions to work (end return the transaction response). If they fail endorsement, fail to send to the orderer, or (if you haven't turned off commit waiting) fail to see successful commit events within a timeout period, you will get an exception. The ContractException will have the proposal responses attached so you can look at any information contained within them, including the error response payload

Hi to anyone . I have a question about speed perfomance and invoke query . Is a good practice to open a gateway everytime i want to run a query or a invoke ? Or is there any other way?
mbwhite (Mon, 12 Oct 2020 07:53:02 GMT):
Hello as @bestbeforetoday suggested in the previous thread - hold on to the gateway (and other objects if at all possible)
Recreating the objects each time is inefficient.
For queries make sure it's a evaluate not a submit.
pkirkinezis (Mon, 12 Oct 2020 08:59:17 GMT):
Yeah i am trying to find a way to keep specific gateway (with chaincode and channel) persistent in every request
pkirkinezis (Mon, 12 Oct 2020 08:59:28 GMT):
is that a good aproach ?
mbwhite (Mon, 12 Oct 2020 09:39:21 GMT):
yes if you can do that..
pkirkinezis (Mon, 12 Oct 2020 13:27:56 GMT):
It is hard to persist an object in java with specific user input . Bean is not working in my case
bestbeforetoday (Tue, 13 Oct 2020 08:32:41 GMT):
Persisting sounds to me like serializing it, either to some persistent storage or perhaps to something like an HTTP session. You definitely *don't* want to do this with a Gateway or Network object
bestbeforetoday (Tue, 13 Oct 2020 08:35:52 GMT):
A simple example of where you would want to keep hold of a Gateway is a client application that is going to submit (or evaluate) multiple transactions. Create the Gateway, Network and Contract once, use them for all of your transactions, then close the Gateway at the end
pkirkinezis (Tue, 13 Oct 2020 08:37:12 GMT):
How can i persist of the Gateway/ contact ?
bestbeforetoday (Tue, 13 Oct 2020 08:37:36 GMT):
If you are running an intermediary, like a REST server, which is submitting transactions driven by client requests, you're probably either:
1. Using a single Fabric client identity for the REST server; or
2. Using different Fabric client identities for each "user" driving REST requests into the system
pkirkinezis (Tue, 13 Oct 2020 08:37:51 GMT):
Simply how can i create a gateway/contract once and use it in every HTTP api request
bestbeforetoday (Tue, 13 Oct 2020 08:38:27 GMT):
If your intermediary using a single "system" Fabric identity, just have it create a Gateway instance with that identity, and keep hold of that Gateway for use by all the requests that arrive at your intermediary
pkirkinezis (Tue, 13 Oct 2020 08:39:07 GMT):
After login success I use the the specific user who logged in to interact
pkirkinezis (Tue, 13 Oct 2020 08:39:25 GMT):
So i have one hyperledger fabric user for every application user .
pkirkinezis (Tue, 13 Oct 2020 08:40:08 GMT):
I don't use one identity to create only a sigle instance of gateway .
bestbeforetoday (Tue, 13 Oct 2020 08:40:30 GMT):
If you have different Fabric identities for each user then you've got to find the right balance. For a very low transaction rate it might be OK to just create and close a Gateway around every request
pkirkinezis (Tue, 13 Oct 2020 08:41:12 GMT):
Yes I do it this way but its a little slow that way .
bestbeforetoday (Tue, 13 Oct 2020 08:41:27 GMT):
For any kind of transaction load you probably want to save those Gateway instances and reuse them. So you might need to have some kind of cache of Gateway instances keyed by client identity
pkirkinezis (Tue, 13 Oct 2020 08:41:40 GMT):
it takes around 2s for gateway to connect for every user.
bestbeforetoday (Tue, 13 Oct 2020 08:42:53 GMT):
Something as simple as a Map of identity name to Gateway instance might be sufficient
pkirkinezis (Tue, 13 Oct 2020 08:44:21 GMT):
xm yeah good idea i will try to create a global mapper of id/conctact and retrive when needed
bestbeforetoday (Tue, 13 Oct 2020 08:44:30 GMT):
As usual with caches, getting things in there is the easy part. Depending on your system and workload, you might need to put some work into taking out of the cache things that don't need to be there anymore
bestbeforetoday (Tue, 13 Oct 2020 08:44:54 GMT):
I expect there are some pre-written caching libraries out there that might be useful but I don't have any recommendations
pkirkinezis (Tue, 13 Oct 2020 08:45:39 GMT):
Yeah i tried it with @bean springboot . Maybe i will try @autowire a map
pkirkinezis (Tue, 13 Oct 2020 08:46:18 GMT):
I use a network resolver and tried to autowire it but it doesn't work as we described
bestbeforetoday (Tue, 13 Oct 2020 08:47:00 GMT):
Just remember that it is the Gateway that needs to eventually have `close()` called on it, so don't lose your Gateway objects
pkirkinezis (Tue, 13 Oct 2020 08:47:45 GMT):
Yeah so gateway is not closing by it self?
pkirkinezis (Tue, 13 Oct 2020 08:47:55 GMT):
after maybe somtime of inactivity?
pkirkinezis (Tue, 13 Oct 2020 08:48:28 GMT):
Maybe i will have to craete /logout api call to run .close()
bestbeforetoday (Tue, 13 Oct 2020 09:28:22 GMT):
The underlying gRPC connection may get closed after some idle period, but the Gateway objects themselves don't have any kind of timeout where they clean up resources

pkirkinezis (Wed, 14 Oct 2020 06:02:08 GMT):
Thats the best way i can thing of for now
bestbeforetoday (Wed, 14 Oct 2020 08:06:34 GMT):
For a TLS connecton to nodes, you just need a `grpcs` rather than `grpc` endpoint URL, and for the CA certificates for your network to be trusted by your client. One option for making the CA certificates available is to include them in your connection profile, as in this connection profile: https://github.com/hyperledger/fabric-gateway-java/blob/master/src/test/java/org/hyperledger/fabric/gateway/connection-tls.json
bestbeforetoday (Wed, 14 Oct 2020 08:14:54 GMT):
I don't know what's best for your application design. If you have the concept of them being logged in or out then a logout seems reasonable, and the cleanup of the Gateway instance could be done when their login session is ended, either by explicit logout or a session timeout. Im sure there are plenty of other approaches that would be viable too, such as a timeout on cached Gateway entries based on when they were last accessed. Or you could wrap the Gateway instance in your own Gateway implementation where a call to `close()` doesn't actually close the wrapped Gateway but is used to track when it is no longer in use by client code. Whatever works for you

Hi to the community . Is there a way to change the secret (used in registration ) of a registered user in hyperledger fabric via SDK?
pkirkinezis (Thu, 15 Oct 2020 13:11:39 GMT):
A similar functionality like change password on a regular application
pkirkinezis (Fri, 16 Oct 2020 09:03:52 GMT):
I can guess there is no way to change password then ? I 've searched to the java sdk code to find something without a luck
bestbeforetoday (Fri, 16 Oct 2020 09:34:03 GMT):
It's important to understand that this is not a password in the conventional sense -- as in a user ID / password used as your credentials. The enrollment secret is a (one-time) secret that grants you the ability to enroll an identity with the certificate authority. So it allows you to get the CA to issue a signed certificate corresponding to your private key. Your private key is your "password" in the user ID / password sense
pkirkinezis (Mon, 19 Oct 2020 08:18:32 GMT):
So is there a good practice to change secret? For my application secret is the same as user password .
pkirkinezis (Mon, 19 Oct 2020 08:19:59 GMT):
I understood what you are describing . But I don't save anywhere the secret phrase only the user password so i if a user change his password i will have to change the secret also ./

It sounds like what you are doing is, every time a user connects, generate a new private key for that user and get a new signed certificate for that key from the CA. This sounds kinda wasteful, and means that if somebody steals that enrollment secret they can generate their own private keys and have them signed by the CA as being valid credentials for the user
pkirkinezis (Tue, 20 Oct 2020 09:03:06 GMT):
Νο . Not at all . I am generating once keys priv and pem adn save them in database . Also o keep the secret on database to .
pkirkinezis (Tue, 20 Oct 2020 09:03:51 GMT):
Then when the user changes password on the app I call my blockchain api and change only the secret from blockchain and database
bestbeforetoday (Tue, 20 Oct 2020 09:04:14 GMT):
Ah, OK. So you are not calling enroll() again. In which case, why do you need to change the enrollment secret?
pkirkinezis (Tue, 20 Oct 2020 09:04:45 GMT):
because i want for convinient the enrollment secret to be the same as the password the user has in the application
bestbeforetoday (Tue, 20 Oct 2020 09:05:10 GMT):
If you are never going to use the enrollment secret, why does it matter if they are the same?
pkirkinezis (Tue, 20 Oct 2020 09:07:40 GMT):
Yeah I was very so and so for this solution . Because everything is encrypted and then decrepted I can keep the secret once the first time user is registered/enrolled and kleep it the same as long as possible
pkirkinezis (Tue, 20 Oct 2020 09:08:38 GMT):
And use it only when the priv_sk and pem are invalidated or something to enroll the user again.

I tried this in a way to load the generated anchros.tx and create a UpdateChannelConfiguration object and then call `channel.updateChannelConfiguration()` method and pass the respective parameters. However, I get a 400 bad request error. On the orderer log I found this error: "error authorizing update: proto: field "common.ConfigUpdate.channel_id" contains invalid UTF-8".

We have an application that run on the top Fabric 1.4.8 with Java SDK (1.4.8 )
nkl199 (Tue, 10 Nov 2020 13:22:32 GMT):
the recommendation is to move to the gateway
conanoc (Wed, 11 Nov 2020 02:05:21 GMT):
You seem to use fabric-node-sdk. I'm looking for a solution with java-sdk.

Hey to the communit when gateway reply "Transaction commit was rejected by peer" what that means ? Where I have to start debugging on chaincode level or network level?
bestbeforetoday (Thu, 12 Nov 2020 16:12:19 GMT):
Just as background, what has happened is that:
1. The transaction proposal has obtained endorsement(s)
2. The endorsed transaction submitted to the orderer
3. Orderer has committed the transaction to a block and distributed to peers
4. Peer has failed to validate the transaction so it has not updated the ledger
5. Client has received the block event containing the transaction, noticed that it is marked invalid, and thrown an exception back to your application
bestbeforetoday (Thu, 12 Nov 2020 16:14:45 GMT):
The reason for the commit failure might be an MVCC failure, where the ledger state touched by the transaction is different to the state when endorsement occurred. So two or more concurrent transactions accessed and/or modified the same ledger keys
bestbeforetoday (Thu, 12 Nov 2020 16:15:23 GMT):
It might be that it didn't meet the endorsement requirements for the operation performed
bestbeforetoday (Thu, 12 Nov 2020 16:15:47 GMT):
The place to look is the peer logs to get more details on the cause
bestbeforetoday (Thu, 12 Nov 2020 16:17:11 GMT):
At the client end, the ContractException thrown should have all the proposal responses attached to the exception, which might help in diagnosing the problem, particularly once the cause is clear from the peer logs
pkirkinezis (Thu, 12 Nov 2020 16:18:25 GMT):
my peers are on multiple different serversbut on my network config i have only the peers of the node i enrolled
bestbeforetoday (Thu, 12 Nov 2020 16:21:08 GMT):
If you are using discovery, the client will discover (at runtime) all of the network nodes, even if they are not in your connection profile
pkirkinezis (Thu, 12 Nov 2020 16:22:31 GMT):
how i can check that?
bestbeforetoday (Thu, 12 Nov 2020 16:23:11 GMT):
If you are not using discovery and your configuration profile doesn't contain enough peers (or peers from enough different organizations) to meet endorsement requirements, that might result in submitted transactions failing to successfully commit
bestbeforetoday (Thu, 12 Nov 2020 16:24:12 GMT):
You need to find the reason for the failure in the peer logs to know how to resolve the issue. All the network peers receive the same committed blocks so you should be able to look in the logs of any network peer
pkirkinezis (Thu, 12 Nov 2020 16:24:27 GMT):
is discovery mode set to channel config ?

Hi All!
How Java sdk Client can get the payload of an Exception that is generated from Chaincode via ChaincodeException?
The Chaincode throw a ChaincodeException with a String Message and String payload.
I can get Message of the ChaincodeException from Client sdk java but I miss how I can get the payload Exception for do operations relied upon the payload
Thanks very much
bestbeforetoday (Thu, 19 Nov 2020 12:06:41 GMT):
Using _fabric-gateway-java_ the `ContractException` thrown should have all the proposal response objects attached:
https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/ContractException.html#getProposalResponses()
bestbeforetoday (Thu, 19 Nov 2020 12:11:37 GMT):
You should be able to pick the payload bytes from them, something along the lines of:
```
byte[] payload = e..getProposalResponses().stream()
.map(ProposalResponse::getProposalResponse)
.map(FabricProposalResponse.ProposalResponse::getPayload)
.filter(Objects::nonNull)
.findFirst()
.map(ByteString::toByteArray)
.orElse(null);
```
bestbeforetoday (Thu, 19 Nov 2020 12:11:37 GMT):

.findFirst()
.map(ByteString::toByteArray)
.orElse(null);
```
lupass93 (Thu, 19 Nov 2020 12:41:34 GMT):
I tried this way, but unfortunately the payload is empty, although in the Chaincode it actually passes to the Constructor of ChaincodeException both the String Message and the String payload.
lupass93 (Thu, 19 Nov 2020 12:42:54 GMT):
As if the payload did not reach Contractexception
bestbeforetoday (Fri, 20 Nov 2020 10:38:09 GMT):
I could easily be missing something but, having a quick look at the Java chaincode implementation, I don't think the payload from the ChaincodeException is being included in the proposal response. It might be worth raising a bug report in Jira: https://jira.hyperledger.org/projects/FABCJ

HI all, Is fabric-java-sdk compatible with the new features available in 2.3.0?(Specifically removing the need for a system channel)?
yacovm (Mon, 30 Nov 2020 15:16:02 GMT):
It's a REST API... you don't need SDK to support it
vijay5378 (Mon, 30 Nov 2020 15:41:10 GMT):
When you try HFClient.newChannel(), you get an error : "channel001 expected config block type CONFIG_UPDATE, but got: MESSAGE". The same code executes normally when there was a system channel and a channel configtx was created using -outputCreateChannelTx.

Hi to the community i would like to ask a question . On my API implementation i have a /logout that also runs gateway.close() . The function gateway.close() takes around 3-5 seconds to run and makes my logout functionality slow.
pkirkinezis (Tue, 01 Dec 2020 06:50:24 GMT):
Any suugestions?
bestbeforetoday (Tue, 01 Dec 2020 09:23:19 GMT):
I suspect the time is being spent closing down the lower-level SDK Channel(s) underpinning the Gateway implementation: https://github.com/hyperledger/fabric-sdk-java/blob/ee596ea3786958a30852eda1987511080d49b2b8/src/main/java/org/hyperledger/fabric/sdk/Channel.java#L6257
bestbeforetoday (Tue, 01 Dec 2020 09:24:28 GMT):
The Gateway calls this shutdown with the `force` argument as `false`. It might be we could speed things up by changing it to a force shutdown but I'm not sure if this is preferable to letting things shutdown gracefully
bestbeforetoday (Tue, 01 Dec 2020 09:26:08 GMT):
I guess ideally it would be good to pin exactly what piece within that channel shutdown is causing the delay and see if that can be changed to make it faster
bestbeforetoday (Tue, 01 Dec 2020 09:27:58 GMT):
Perhaps as a workaround from your application level you could use an `ExecutorService` to run the `gateway.close()` on a separate thread and complete your shutdown as soon as the close has been scheduled to run rather than waiting for it to complete
bestbeforetoday (Tue, 01 Dec 2020 09:29:55 GMT):
Feel free to raise an issue in Jira to record this issue though: https://jira.hyperledger.org/projects/FGJ

sijo.c (Thu, 03 Dec 2020 22:13:27 GMT):
Can this happen due to unstable network etc, or can this be an app issue resulting in write conflict?
bestbeforetoday (Fri, 04 Dec 2020 10:25:19 GMT):
If the transaction fails to commit (i.e. the client receives a block event containing the transaction and it is marked as unsuccessful) then I would expect to get an exception reading something like:
> Transaction commit was rejected by peer peer1.example.org
bestbeforetoday (Fri, 04 Dec 2020 10:27:17 GMT):
I suspect that the gRPC event stream to all of the peers has failed and so the client has given up trying to observe the commit
bestbeforetoday (Fri, 04 Dec 2020 10:27:38 GMT):
So definitely this could be caused by an unstable network
bestbeforetoday (Fri, 04 Dec 2020 10:28:21 GMT):
The transaction may have in fact committed fine. The client just doesn't know because it failed to observe either a commit success or failure

can any one help with my questions above? As may I modify security related config items in config.properties file to change settings such as using other curve for encrypt and decrypt works?
bestbeforetoday (Wed, 09 Dec 2020 18:22:03 GMT):
@SamYuan1990 all the signing should be done by the `CryptoSuite` implementation set on the `HFClient` using `setCryptoSuite()`. So I guess you should be able to just construct your own implementation of the `CryptoSuite` interface that does signing by whatever method you choose when its `sign()` method is called with the user context's private key and message bytes to sign
bestbeforetoday (Wed, 09 Dec 2020 18:30:41 GMT):
As we're developing the multi-language _fabric-gateway_ API, I'm trying to make this easier by just having the client application explicitly pass in a signing implementation function, with default signing implementations provided for standard methods such as P-256 with EC private key:
https://github.com/hyperledger/fabric-gateway/blob/c4f708d09c7525ca689fc7116119de134c60cca8/java/src/main/java/org/hyperledger/fabric/client/Gateway.java#L103

Hello, I am a little bit confused on how to store data in the ledger. Basically, I read the fabric-sdk-java documentation, and the sample they were using was something like this:
...
try (Gateway gateway = builder.connect()) {
Network network = gateway.getNetwork("mychannel");
Contract contract = network.getContract("fabcar");
...
However, the theory says that, first, a proposal must be validated by the committing peers, and then, it should be submitted to the orderer node. Something like this:
...
Collection transactionPropResp = channel.sendTransactionProposalToEndorsers(transactionProposalRequest);
Collection transactionPropResp = channel.sendTransactionProposal(transactionProposalRequest, channel.getPeers());
...
I would like someone to tell what's the difference, because I am trying to figure it out why I am getting a consistency responses problem.
Sorry If this is a newbie question,
thanks in advance

The filesystem is not read every time you submit a transaction. The identity is read from the wallet at the point you connect the Gateway. You should not be throwing away your Gateway and re-connecting on every transaction. This will be a much bigger performance impact that reading a small (likely cached) file from the filesystem as it will discard and re-establish gRPC network connections on every transaction
bestbeforetoday (Tue, 19 Jan 2021 11:23:27 GMT):
You've also got the option of reading the wallet identity into memory as an Identity object and connecting Gateway using only that in-memory object: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Gateway.Builder.html#identity(org.hyperledger.fabric.gateway.Identity)
bestbeforetoday (Tue, 19 Jan 2021 11:24:59 GMT):
Or if it's easier to manage a collection of in-memory Identity objects then you can stick them into an in-memory wallet for the lifetime of your application: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Wallets.html#newInMemoryWallet()
bestbeforetoday (Tue, 19 Jan 2021 11:28:15 GMT):
A singe call to `contract.submitTransaction("txName", "arg1", "arg2")` will do the following:
1. Send a proposal to peers for endorsement
2. Submit a transaction (including endorsments) to the orderer
3. Wait for transaction events from peers to confirm the transaction committed successfully
bestbeforetoday (Tue, 19 Jan 2021 11:37:19 GMT):
The _fabric-sdk-java_ API has some Lifecycle-related functions on `HFClient` and `Channel`:

This error suggests that the transaction was successfully sent to the orderer for commit but all the peers the client expected to receive events from disconnected before the client received block events including the committed transaction
bestbeforetoday (Thu, 04 Feb 2021 14:16:36 GMT):
One possible cause is that idle connections are being closed very aggressively between the client and peers. If this is the case then changing the default gRPC keep-alive times may help to prevent the event listening connections from being closed

Unfortunately not but you can work around this by explicitly specifying the set of peers to use for endorsement using `Transaction.setEndorsingPeers()`: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Transaction.html#setEndorsingPeers(java.util.Collection)

ndr_brt (Fri, 26 Feb 2021 08:06:28 GMT):
hi to everyone, I can't find a channel for fabric-gateway so I will ask here.
there's a way, in fabric gateway, to catch concurrent modification exceptions? the `contract.submitTransaction` method exits with a `ContractException` that does not contains references to the kind of error.
I know that this is possible in fabric-sdk-java (catching CompletionException and extracting its cause TransactionEventException that contains the `11` validation code), but would be nice if this could be possible also in fabric-gateway.
bestbeforetoday (Fri, 26 Feb 2021 10:50:43 GMT):
Right now that transaction validation code is getting swallowed by the fabric-gateway code. I agree that would be useful information to pass back to the caller. I guess you've just raised the feature request in Jira? https://jira.hyperledger.org/browse/FGJ-103
bestbeforetoday (Fri, 26 Feb 2021 10:51:00 GMT):
If so, thank you for raising that :thumbsup:
bestbeforetoday (Fri, 26 Feb 2021 11:05:13 GMT):
There is actually a work-around you could employ, which is to implement your own commit handler so you deal with the committed transactions directly and can pull out whatever information you need: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/spi/CommitHandlerFactory.html
bestbeforetoday (Fri, 26 Feb 2021 11:05:25 GMT):
There is sample code linked there that you can just cut & paste
bestbeforetoday (Fri, 26 Feb 2021 11:06:27 GMT):
You register the default handler on the Gateway connect: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Gateway.Builder.html#commitHandler(org.hyperledger.fabric.gateway.spi.CommitHandlerFactory)
bestbeforetoday (Fri, 26 Feb 2021 11:06:58 GMT):
Or you can register a specific handler to use per transaction invocation: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Transaction.html#setCommitHandler(org.hyperledger.fabric.gateway.spi.CommitHandlerFactory)
bestbeforetoday (Fri, 26 Feb 2021 11:07:52 GMT):
But again I think having the exception thrown from the submit include this information for you would be nicer
ndr_brt (Fri, 26 Feb 2021 11:10:15 GMT):
Thanks for the reply, I'm creating a pull request for the case.
In the meantime I will try with the CommitHandler approach.
bestbeforetoday (Fri, 26 Feb 2021 11:23:19 GMT):
If you want to make the code change, that's great. It might be worth defining a `CommitException` as a subclass of the `ContractException`, and which includes the `BlockEvent.TransactionEvent`. Calling code can pull the transaction status and any other information they might want from that event object
bestbeforetoday (Fri, 26 Feb 2021 11:23:55 GMT):
I think the only code you'll need to change is in `CommitHandlerImpl.onTxEvent()`
bestbeforetoday (Fri, 26 Feb 2021 11:27:51 GMT):
I would also declare the exception explicitly on `Contract.submitTransaction()` and `Transaction.submit()` along with accompanying Javadoc
bestbeforetoday (Fri, 26 Feb 2021 11:28:39 GMT):
If you're working on it, assign the Jira to yourself and move it into working state

bestbeforetoday (Tue, 09 Mar 2021 11:55:34 GMT):
Is there any context to stack trace around that? It doesn't ring any bells as a client-side error, so is that something you're seeing from the peer end? If so, one of the other channels might get more visibility from core Fabric contributors and maintainers

bestbeforetoday (Tue, 09 Mar 2021 12:07:08 GMT):
That NoClassDefFoundError looks bad. I wonder if some versions of gRPC / Netty packages are out of step. It might be worth clearing out your local Maven repository cache and trying again. Also check if any of your code has direct (or indirect) dependencies on those Netty packages. `mvn dependency:list` and `mvn dependency:tree` might help. If you can't get to the bottom of it and it's easily reproducible then you could raise a bug report in Jira with all the dependency and version information (including the SDK version): https://jira.hyperledger.org/browse/FGJ
pkirkinezis (Tue, 09 Mar 2021 12:35:11 GMT):

bestbeforetoday (Fri, 26 Mar 2021 14:30:42 GMT):
I would recommend not using the SDK to create the network. Instead, look at the example of creating and configuring a network in the Fabric samples: https://hyperledger-fabric.readthedocs.io/en/latest/test_network.html
bestbeforetoday (Fri, 26 Mar 2021 14:32:11 GMT):
When it comes to developing a client application using the SDK, there is a section in the main Fabric docs on developing applications that describes all the concepts, although I think the code examples are all JavaScript. The asset-transfer-basic sample might be a good place to start for Java: https://github.com/hyperledger/fabric-samples/blob/main/asset-transfer-basic/application-java/src/main/java/application/java/App.java

But why not using the SDK to create a network? What if I want to create and manage a network programmatically?
I am aware of the client application using SDK. That's about invoking a transaction, right?

You should add extra host in you docker-compose file. where you can bridge the your IP address and your domain name for example. extra_hosts:
- "peer0.example.com:172.x.x.x"
-"peer1.example.com:172.x.x.x"
cmhacker (Mon, 29 Mar 2021 17:40:17 GMT):
Similarly you can do this for orderer

Hi Everyone, Using contract.submitTransaction() is taking more time by waiting for commit events. So, Is there is a way to improve the performance using fabric sdk java?
cmhacker (Tue, 20 Apr 2021 10:27:21 GMT):
check your configtx.yaml file and changed if BatchTimeout: 2s then changed it to BatchTimeout: 0.1s
cmhacker (Tue, 20 Apr 2021 10:27:21 GMT):
check your configtx.yaml file and changed BatchTimeout: 2s to BatchTimeout: 0.1s
bestbeforetoday (Tue, 20 Apr 2021 10:37:55 GMT):
You'll find that as you push more concurrent load into the system the blocks get cut faster as you hit the setting for maximum transactions in a block quicker than the the batch timeout
bestbeforetoday (Tue, 20 Apr 2021 10:39:15 GMT):
I'd be wary of setting the batch timeout very low as this may mean that under load you don't have time to get so many transactions batched into each block. Although some benchmarking would help find the best trade-off for your case
bestbeforetoday (Tue, 20 Apr 2021 10:41:21 GMT):
If your transactions don't touch the same ledger keys so it's safe to submit subsequent transactions before previous ones commit, you can use multiple threads at the client end to submit multiple transactions concurrently
bestbeforetoday (Tue, 20 Apr 2021 10:42:44 GMT):
Or if you don't want to wait for the commits to be confirmed, you can use the `DefaultCommitHandlers.NONE` commit handler: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/DefaultCommitHandlers.html#NONE
bestbeforetoday (Tue, 20 Apr 2021 10:43:31 GMT):
You can specify either a default commit handler for all transactions when connecting the Gateway: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Gateway.Builder.html#commitHandler(org.hyperledger.fabric.gateway.spi.CommitHandlerFactory)
bestbeforetoday (Tue, 20 Apr 2021 10:44:07 GMT):
Or specify the commit handler to use for each transaction: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Transaction.html#setCommitHandler(org.hyperledger.fabric.gateway.spi.CommitHandlerFactory)

Bolzo 1 (Mon, 26 Apr 2021 15:05:34 GMT):
Hi all! Is there a way to determine if the network (endorsing peer) is down? I create a Gateway connection the usal way then with my Gateway object I do this `Network channel = gateway.getNetwork(channelName);`
This logs this error `ERROR org.hyperledger.fabric.sdk.Channel - Channel Channel{id: 1, name: mychannel1} Sending proposal with transaction: 0a65bd570e0dcc1e78199d5540c05339072f0eaa95e1a5e4cb6ade6a0e6508b7 to Peer{ id: 2, name: peer0.org2.mydomain.com, channelName: mychannel1, url: grpcs://peer0.org2.mydomain.com:YYYY1, mspid: Org2MSP} failed because of: gRPC failure=Status{code=UNAVAILABLE, description=io exception, cause=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: peer0.org2.mydomain.com/x.x.x.x:YYYY

But it seems that is not rethrown to my call so I cannot catch it in my try catch block.
My problem is that after that call to get the channel i start doing parallel work using `commitListener` and my calls go on timeout as expected.
I wonder if there is a way to understand when the gateway can't connect to the network and avoid useless instructions.
My understanding of this behaviour (logging and not throwning) is that maybe the connection it's restablished after the error log, dunno if I'm wrong on this

If I use evaluateTransaction it works without any error.
konda.kalyan (Mon, 31 May 2021 06:22:46 GMT):
My guess is that, Submittransaction is not run succssfully on required number of peers (as per the endorsement policy). Check if the transaction/chaincode has run all required number of peers or not. On the other hand, it is sufficient that evaluateTransaction is required to run any one endorsing peer and don't need to satisfy the endorsement policy.
bestbeforetoday (Tue, 01 Jun 2021 09:42:34 GMT):
Strange that evaluate is working but submit is failing during endorsement, as the evaluate is effectively just an endorsement. Is there a stacktrace to help pinpoint where the error is coming from?

They are actually wrapper objects around the actual protobuf classes, and are defined by the low-level (fabric-sdk-java) SDK. They loosely mirror the protobuf structure (which is fairly convoluted) but should provide methods for you to navigate down to all the information you need: https://javadoc.io/doc/org.hyperledger.fabric-sdk-java/fabric-sdk-java/latest/org/hyperledger/fabric/sdk/BlockEvent.html

Under https://github.com/hyperledger there are many Java Client SDK projects like fabric-gateway / fabric-gateway-java / fabric-sdk-java...
why are there so many Java clients ?
how do I choose which one to use ?
bestbeforetoday (Tue, 08 Jun 2021 09:08:11 GMT):
I appreciate it could be more obvious. The README for each repo does give some guidance though. From *fabric-sdk-java*
> This project provides a low-level API for interacting with Hyperledger Fabric blockchain networks, and is used by the high-level Hyperledger Fabric Gateway SDK for Java
bestbeforetoday (Tue, 08 Jun 2021 09:08:36 GMT):
So that points to *fabric-gateway-java* as the API to use
bestbeforetoday (Tue, 08 Jun 2021 09:12:08 GMT):
The *fabric-gateway* API (https://github.com/hyperledger/fabric-gateway) is still under development. It provides a consistent client API in Java, Go and Node, with much of the heavy-lifting moved to a server-side Fabric Gateway component, implemented in the peer. This capability does not exist in any released version of Fabric, only in development builds. So this will likely become the preferred API in the future but is not the one to pick for applications you want to deploy right now. Feedback and suggestions on the Fabric Gateway API are very welcome

@indranil32 This is a bit worrying. The builds for both _fabric-gateway-java_ and the low-level _fabric-sdk-java_ on which it is built are both showing their tests passing. I see that the _fabric-gateway-java_ v2.2.x tests are running with _fabric-sdk-java_ v2.2.6 against Fabric v2.2 nodes. Since this looks at first glance to be a purely client-side error, I'm not sure why the Fabric version should be a factor. My suspicion would be some kind of conflict in versions of SDK and/or gRPC/protobuf library versions in your environment compared to what are running in the automated builds. Could you raise a bug report in Jira including as much information as you can on the problem (full stack trace of the errors, `mvn dependency:tree` output, and _ideally_ an extremely simple client project, perhaps using one of the sample networks, that can be used to reproduce the error): https://jira.hyperledger.org/projects/FGJ

Why does this limitation exist in Fabric? It limits the development of smart contracts that can be called by other contracts. Listening to events defined in the called-contract is not possible and it requires to listen to the outer-most contract, which could be complicated if there are multiple ones. Anyone has an idea how to overcome this?
https://hlf.readthedocs.io/en/latest/developapps/transactioncontext.html#stub
setEvent(): Smart contracts use this API to add an event to a transaction response. *Note that only a single event can be created in a transaction, and must originate from the outer-most contract when contracts invoke each other via invokeChaincode. * ...

Currently, PeerEventServiceClient connects to all the peers on the network (even the one not from my organisations). If a peer is down due to some reason, it leads to increase in CPU usage due to connection retries.
1. Can we have a mechanism to restrict PeerEventServiceClient to only connect to peers from my organization or something?
2. Also do we have some docs around Event service features. We are banking on it, I want to read on recommeded practices for delivery guarantees and everything
bestbeforetoday (Mon, 14 Jun 2021 08:37:14 GMT):
You're right that the Java SDK maintains eventing connections to all network peers. It would be possible to change this behaviour but I suspect it would be quite a lot of work, and it's not something I am likely to have time to do, but anyone can contribute changes. It looks like the config property `org.hyperledger.fabric.sdk.peer.retry_wait_time` (or as the environment variable `ORG_HYPERLEDGER_FABRIC_SDK_PEER_RETRY_WAIT_TIME`) should set the wait time between connection attempts, so setting that higher than the default 500ms might help
bestbeforetoday (Mon, 14 Jun 2021 08:41:54 GMT):
The fabric-gateway-java API should ensure that you receive events in order and without duplication, regardless of whether peers being used for eventing go down or come back online: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Network.html#addBlockListener(java.util.function.Consumer)
bestbeforetoday (Mon, 14 Jun 2021 08:44:38 GMT):
You an use a Checkpointer for either block or contract/chaincode event listening. This makes it easier to track the last processed event and allow your client application to resume listening from where it left off after a restart: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Contract.html#addContractListener(org.hyperledger.fabric.gateway.spi.Checkpointer,java.util.function.Consumer)
bestbeforetoday (Mon, 14 Jun 2021 08:46:15 GMT):
There is a Checkpointer implementation provided that writes its state to a local file, or you can provide your own Checkpointer implementation: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/DefaultCheckpointers.html#file(java.nio.file.Path)

bestbeforetoday (Tue, 22 Jun 2021 10:44:23 GMT):
You attach a listener function that will get invoked when your chaincode emits events using the Contract's `addContractListener()` methods: https://hyperledger.github.io/fabric-gateway-java/release-2.2/org/hyperledger/fabric/gateway/Contract.html

Sorry for not getting back to you more quickly. I'm just getting to this now. Perhaps you could start by creating a story in Jira with a description of the behaviour you want to implement and we can refine from there? https://jira.hyperledger.org/projects/FGJ/
bestbeforetoday (Tue, 22 Jun 2021 11:09:48 GMT):
The Node SDK is implemented differently and only tries to pull events from a single peer at a time. It may be a bit ambitious to try to make such a big change to the Java SDK
bestbeforetoday (Tue, 22 Jun 2021 11:11:20 GMT):
The pool of peers selected for eventing by the Node SDK is limited to the peers in the client's org (unless there are no peers in their org, in which case all network peers are considered). An approach similar to this might be more practical for the Java SDK
bestbeforetoday (Tue, 22 Jun 2021 11:12:49 GMT):
So only peers in the client's org are marked as having the `PeerRole.EVENT_SOURCE` role, and that role is not included for peers in other orgs
bestbeforetoday (Tue, 22 Jun 2021 11:13:49 GMT):
So the SDK would still be actively receiving events from multiple peers, but only peers in the client's org
bestbeforetoday (Tue, 22 Jun 2021 11:15:30 GMT):
Just need to consider the case where the client's org does not have any peers, and how to deal with that. A simple option might be to have a configuration flag, but this makes it much easier for clients to get it wrong and be confused why eventing isn't working. Better would be to be able to detect that condition automatically and react appropriately

Hi, I am looking at the old questions about the functionality to sign transactions (payload) offline and the proposed solutions to use a custom CryptoSuite class that implements the sign() method. Reading this recommendation I'm asking myself if the SDK will tolerate a couple of remote calls (for example a request to a remote Wallet/HSM device to sign the payload in a secure environment). Is this use case scenario not considered as a possible one, during the design of the fabric-sdk-java? Thanks.

I don't know the intent of the people who designed and developed the low-level fabric-sdk-java but, from the presence of the CryptoSuite as a pluggable element, I think there was an intention to allow alternative signing implementations to be provided. I don't see why using an HSM for signing shouldn't be included in that, and it is supported in a similar manner in the Node SDK
bestbeforetoday (Tue, 29 Jun 2021 09:11:22 GMT):
I don't see any reason why HSM signing can't be made to work with the Java SDK. It's just a question of time and effort to implement it
bestbeforetoday (Tue, 29 Jun 2021 09:14:13 GMT):
The CryptoSuite itself is quite a large interface to implement so just support signing, so it's not necessarily the easiest job, but perhaps some elements of it not used purely for signing can be either delegated to the existing CryptoSuite implementation or just not supported (throw `UnsupportedOperationException`) to make it easier to implement if you only need signing and not the CA operations like enrollment
bestbeforetoday (Tue, 29 Jun 2021 09:17:44 GMT):
The _fabric-gateway_ API being developed right now was designed to better decouple the signing implementation from the SDK itself and make it very easy to build and use new signing implementations
bestbeforetoday (Tue, 29 Jun 2021 09:18:48 GMT):
The signing implementation is a simple function that you can implement however you want: https://hyperledger.github.io/fabric-gateway/main/api/java/org/hyperledger/fabric/client/identity/package-summary.html
bestbeforetoday (Tue, 29 Jun 2021 09:19:14 GMT):
And this is then just passed in when connecting the Gateway client (see code example here): https://hyperledger.github.io/fabric-gateway/main/api/java/index.html
bestbeforetoday (Tue, 29 Jun 2021 09:35:39 GMT):
For "off-line signing", where the client application doesn't have the client signing credentials and needs to go back to a remote client (e.g. that mobile user) who holds the signing keys, the future Fabric Gateway API has a specific asynchronous flow designed to support that. See Off-line signing examples here: https://hyperledger.github.io/fabric-gateway/main/api/java/org/hyperledger/fabric/client/Contract.html

I couldn't commit to any exact timescale but the current intention is to have a Fabric release supporting a first stable version of that client API late this year. I would guess end of 3Q or later. But that really is purely a statement of intent, not any kind of firm date. It depends on how quickly development progresses, feedback / requirements and any issues we might run into a long the way

At that directory, however the Paths.get() will resolve for where the code is executing. The wallet file must be created by some code, see: https://hyperledger.github.io/fabric-gateway-java/master/org/hyperledger/fabric/gateway/Wallets.html

Hi, I have a question about peer connection using Fabric Gateway. I have a connection profile in which i specify 2 peer of my organization (these peer are also endoring peer, only they have the chaincode installed). Time to time happens that the Gateway automattically tries to send transaction to a peer of another organization in the channel, and that peer is not an endorsing peer. The problem that I face is the fact that the gateway when tries to connect to the other org peer, it uses the logic address (i.e. peer0.otherOrg.com) which cannot be resolved by the dns, so this results in a unknow host exception.
Any thoughts on this? The desired outcome is that my gateway connects only to my org endorsing peers for the submit transaction part.
conanoc (Thu, 05 Aug 2021 01:43:11 GMT):
The behavior seems normal. Clients should connect to peers of other organizations.
What's the endorsement policy of your channel?

Hello, I've a question concerning data loss after rolling back blocks after a transaction error occurs. I'm using a high-throughput ledger, and from time to time the submitted transaction can throw a ContractException due to a IllegalArgumentException.
This happens nearly 1 time in 500 submitted ones, but It causes the ledger to rollback the last 5/6 blocks to a certain security point, causing the loss of data contained in those blocks. I mean, after I catch the exception, surrounding the submitTransaction with a try/catch, I'm able to resend the failed payload and it is processed successfully. However, the data from the previous transactions is lost. What can I do to prevent this?
bestbeforetoday (Tue, 17 Aug 2021 17:30:20 GMT):
If the peer is discarding previously committed blocks, that sounds to me like it could be a more serious issue with the peer itself. You might want to raise an issue
bestbeforetoday (Tue, 17 Aug 2021 17:33:15 GMT):
If it's a client-side SDK failure that shouldn't be happening then it would help to raise an issue against the SDK with as much diagnostic information as you can get, including at the very least the stack trace of the exception being generated, a snippet of the failing client code, and any information on particular inputs/parameters supplied by your client application that trigger the error

The problem causing these errors is related to when a peer has generated a block in pos X and receives from gossip a different block in same position X. Which causes him to discard the received block, losing that information.
Warning Message from peer logs (docker):
2021-08-18 11:12:53.630 UTC [gossip.state] func1 -> WARN c38 Block [681] received from gossip wasn't added to payload buffer: Ledger height is at 682, cannot enqueue block with sequence of 681
deployer21 (Wed, 18 Aug 2021 11:59:38 GMT):
Another question I got is why does blocks are constantly generated with only one transaction in it? I've configured a batch timeout of 1s and a BatchSize.MaxMessageCount of 100. I was expectng that, to generate a new block, I'd have to send 100 messages or something, however, in my network, If I send like 10 new transactions in a second, it generates 10 new blocks in the ledger, with the message: "Committed block [1698] with 1 transaction(s) in 24ms";
ckong (Thu, 19 Aug 2021 03:41:53 GMT):
I have a question about using Fabric Gateway. How can I obtain the transaction ID from contract.submitTransaction()? I tried the longform Transaction t = contract.createTransaction(name), but Transaction doesn't have any ways to return me the transaction ID either.
ckong (Thu, 19 Aug 2021 03:45:02 GMT):
I see Transaction#getTransactionId() in release-2.2, but I'm using release-1.4 because I'm working on Fabric v1.4.x. Is there any other way for me to get the transaction ID?
ckong (Thu, 19 Aug 2021 04:47:41 GMT):
Can I use Gateway release-2.2 to connect to a Fabric network running Fabric v1.4.x? @bestbeforetoday
bestbeforetoday (Thu, 19 Aug 2021 09:22:29 GMT):
That sounds like maybe peer ledgers have somehow diverged. I'm not sure exactly how this might have happened or the best way to fix it, but it doesn't sound good
bestbeforetoday (Thu, 19 Aug 2021 09:29:10 GMT):
If you just want to capture all the transaction IDs submitted then one hack might be to implement your own CommitHandlerFactory, which is set on Gateway connect: https://hyperledger.github.io/fabric-gateway-java/release-1.4/org/hyperledger/fabric/gateway/Gateway.Builder.html#commitHandler-org.hyperledger.fabric.gateway.spi.CommitHandlerFactory-
bestbeforetoday (Thu, 19 Aug 2021 09:31:05 GMT):
Your CommitHandlerFactory implementation could capture the transaction ID and then just defer to one of the default handlers so you don't actually need to implement a complete handler: https://hyperledger.github.io/fabric-gateway-java/release-1.4/org/hyperledger/fabric/gateway/DefaultCommitHandlers.html
bestbeforetoday (Thu, 19 Aug 2021 09:31:34 GMT):
If you can possibly move to v2.2 then your life will be much easier though
ckong (Thu, 19 Aug 2021 09:31:58 GMT):
But would v2.2 be compatible with Fabric v1.4.x?
bestbeforetoday (Thu, 19 Aug 2021 09:34:04 GMT):
Good question. I have seen the v2.2 Node SDK used successfully with v1.4 Fabric (provided you don't use an v2.2-specific features). It's not something I've tried with the Java SDK but you could give it a try. The protobuf and gRPC definitions used for communication between client and peer typically have pretty good compatibility

yacovm (Thu, 19 Aug 2021 09:34:45 GMT):
this doesn't mean it's a different block
yacovm (Thu, 19 Aug 2021 09:35:08 GMT):
it just means that we pulled block 681 but we somehow got block 682 via a different manner so no need for it
yacovm (Thu, 19 Aug 2021 09:35:14 GMT):
it's benign, ignore this warning
bestbeforetoday (Thu, 19 Aug 2021 09:37:58 GMT):
@yacovm Thanks for weighing in! In earlier post @deployer21 says that the peer is actually rolling back / discarding previously committed blocks. This sounds to me like something that shouldn't be possible. I can't say whether it's really happening on the log messages above are just giving a false impression that it is.

yacovm (Thu, 19 Aug 2021 09:38:21 GMT):
what kind of storage is the peer using ?
yacovm (Thu, 19 Aug 2021 09:38:30 GMT):
Is it using an NFS mount?
deployer21 (Thu, 19 Aug 2021 11:03:58 GMT):
@yacovm @bestbeforetoday thank you for your help.
deployer21 (Thu, 19 Aug 2021 11:05:24 GMT):
@yacovm peers are docker containers with volumes being mapped at docker network .yamls.

deployer21 (Thu, 19 Aug 2021 11:13:41 GMT):
@yacovm I don't know why then, some updates that I send to the ledger are being ignored or lost somehow.. I'm saving negotiation results both in application memory and to the ledger, and some assets at the ledger are 100% equal to the ones in memory, while others are like 95% or something..
deployer21 (Thu, 19 Aug 2021 11:15:27 GMT):
I don't see any other error/warning in peer logs that could justify it
deployer21 (Thu, 19 Aug 2021 11:17:28 GMT):
To contextualise you, the values after B(blockchain) should match the values after C(application)

yacovm (Thu, 19 Aug 2021 16:54:57 GMT):
maybe some updates are ignored because they are invalid transactions due to MVCC conflicts?
yacovm (Thu, 19 Aug 2021 16:55:25 GMT):
if this is a high throughput network it makes sense no?
bestbeforetoday (Tue, 24 Aug 2021 16:56:04 GMT):
I suspect your client application isn't driving enough concurrent transaction load for your block cutting configuration. I certainly can observe large numbers of transactions in a single block with a multi-threaded client driving load

And after some 31000 retry's the Txn timeout causes it to stop the flow. But Instantiation happens just fine.

How to reproduce :
1, Clone the fabrice samples,
2, goto fabricsamples\fabcar and start the network.
3, Copy the relevant files and the connection files, fabcar\java- src, pom.xml
4, Run the java client for fabcar from a different machine. ( in may case windows )
Response :
Able to add the Wallets, but getting below grpc comm error.
Steps tried :
Added the org2 peer in connection.yaml file still not resolving..
Added DNS entries, no improvement
expecting: Grpcs should take the hostname/fqdn peer name from the configured variable from the docker-compose file.
Any alternate options to override the setting ? How can i override the hostname setting from the grpcs://localhost:9051 ?

A v0.2.0 pre-release version of the new *fabric-gateway* client API for use with Fabric v2.4 has been published/tagged. This makes use of the new Fabric Gateway service in v2.4 peers, and provides completely consistent functionality to applications written in Go, Node and Java. Provided no stop-ship issues are identified, this is what we are planning to release alongside Fabric v2.4 as a supplement to the existing SDKs so please feel free to try it out and provide feedback.
