Issue in OMM Consumer creation - timeout (New to Refinitiv api)

badal.vishal

I am using following code to test connect to contrib server to publish data.

This is part of sample I got from a link shared by support team. It is failing at OMM Consumer creation.

Can someone please guide what needs to be corrected here?

Output ::

Code ::

AppClient appClient = new AppClient();

System.out.println("Starting encrypted connection...");

// Create an OMM consumer

.password("xxxxxx") // password shared by Refinitiv

.tunnelingKeyStoreFile("C:\\Users\\xxxx\\trcc.jks") //generated jks with *.cer file provided by Refinitiv

.tunnelingKeyStorePasswd("xxxxx"));

.guarantee(EmaFactory.createCosGuarantee().type(CosGuarantee.CosGuaranteeType.NONE));

System.out.println("Starting tunnel stream...");

Hi @badal.vishal

I recall this issue was down to a combination of factors including invalid credentials and also lack of data dictionary files.

With the correct credentials and data dictionary files in the right location, you were able to connect and contribute.

Please confirm if my recollection is correct - if so, accept this post as a correct answer.

Thanks

Hi @badal.vishal

Can you please confirm where you downloaded the sample source code from?

I am comparing your above snippet with the EMA Java RCC Contribution tutorial code from here and your code looks quite different in terms of the OMMConsumer initialisation

Looking at the above tutorial, the OMMConsumer creation code is:

OmmConsumer consumer = EmaFactory.createOmmConsumer(EmaFactory.createOmmConsumerConfig().tunnelingKeyStoreFile("KEYSTORE_FILE_NAME")
       .tunnelingKeyStorePasswd("KEYSTORE_PASSWORD"));

and the username + password are not submitted until a StatusMsg is received confirming the tunnel stream is open.

Also, please confirm with your Refinitiv account team that the username and password you are using are RCC specific.

Hi @umer.nalla,

Earlier I used that only, but that was throwing same error, so I added these.

Both have same error, and yes, I am using the same sample code.

Please help.

Hi @badal.vishal

Using the original unchanged sample please carry out the Troubleshooting steps detailed at the end of the above tutorial.

First, if you have not already done so, verify the Comodo CA using the keytool command as described.

Then, enable the EMA Java logging and the JDK network logging as described.

Once enabled, please capture the log output to a file and upload the file here as an attachment - removing any private credential information.

@umer.nalla.nalla Please check the uploaded log, and suggest please.

I used following commands to create keystore and jks :

"c:\Program Files\Java\jdk-11.0.8\bin\keytool.exe" -genkey -alias trcc -keyalg RSA -keystore trcc -storepass yourpassword

"c:\Program Files\Java\jdk-11.0.8\bin\keytool.exe" -list -v -keystore trcc -storepass yourpassword

"c:\Program Files\Java\jdk-11.0.8\bin\keytool.exe" -printcert -v -file COMODORSAOrganizationValidationSecureServerCA.crt

"c:\Program Files\Java\jdk-11.0.8\bin\keytool.exe" -import -trustcacerts -alias trccnew -file COMODORSAOrganizationValidationSecureServerCA.crt -keystore trcc -storepass yourpassword

"c:\Program Files\Java\jdk-11.0.8\bin\keytool.exe" -list -v -keystore trcc -storepass yourpassword -alias trccnew

Hello @badal.vishal
We cannot download the "logs.txt" file, could you please enable the network log as described in the Troubleshooting section of the tutorial, and re-upload the file (please remove your personal credential detail from the file first).

Additionally, do you run the application behind a firewall or any VPN?

badal.vishal

Hi @wasin.w I am running it from my local office machine.

I am reuploading the file if that works.

ServerHello, ClientHello happens, trcc found and then PKIX path building issue.

Snippet from log file :

"throwable" : {

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
