Unable to call Functions from a JAR file

[Rafiq_123]

Hi,

I have a JAR file to call user-defined functions from Server A(Dev version) which I need to call in my Report Studio. This works fine as long as I'm calling the function from my Dev Cognos RS. But when, placing the same JAR file pointing to Server B(QA version) into my QA environment, the function gets executed successfully (no error thrown) but output is not returned (or null value returned). I have tried re configuring the JAR file(in QA environment) to point to Server A, still no output.

PS: Cognos 10.2.2 is being used, Linux 64 bit for Cognos server. The Package was built in DQM mode.

How do I ensure/confirm that the DQM mode is still retained in QA after exporting the package to QA server.

Appreciate your help.
