Failed to run demo java code for contribution

Hi, I am trying to run this tutorial: https://developers.refinitiv.com/en/api-catalog/refinitiv-real-time-opnsrc/rt-sdk-java#ema-consumer-posting-data-to-contribution-channel

I think the code with problem is this line: 

OmmConsumer consumer = EmaFactory.createOmmConsumer(EmaFactory.createOmmConsumerConfig()
                 .tunnelingKeyStoreFile("clientkeystore")
                 .tunnelingKeyStorePasswd("test123"));

I got following error message:

Contributing to TR Contributions Channel

Starting encrypted connection...

Oct 29, 2018 10:44:53 AM com.thomsonreuters.ema.access.ChannelCallbackClient reactorChannelEventCallback WARNING: loggerMsg

Severity: Warning

Text: Received ChannelDownReconnecting event on channel Channel_1 RsslReactor Channel is null

Error Id 0 Internal sysError 0

Error Location Reactor.processWorkerEvent

Could you please help? Thanks

Zhe

Hi @zhe.wang, For TRCC contribution, try service name DDS_TRCE. You should have receive this along with the login credentials.

Hello @zhe.wang. Have you tried the troubleshooting steps in the tutorial? Specifically the ones about turning on JDK network logging, and adding the CA certificate to your keystore.

Hi Gurpreet, with your help, now I can build the encrypted.

The next problem I got is, what kind of CONTRIBUTION_SERVICE_NAME should I input to run the tutorial? It is related to following code: 

// Create a request for a tunnel streamTunnelStreamRequest tsr = EmaFactory.createTunnelStreamRequest()
   .classOfService(cos)
   .domainType(EmaRdm.MMT_SYSTEM)
   .name("TUNNEL1")
   .serviceName("CONTRIBUTION_SERVICE_NAME");
