java.lang.UnsatisfiedLinkError: cqjnilinuxproxy (Not found in java.library.path)

Question

I have webservices deployed on WAS that use Clearquest jars to connect to Clearquest. At runtime, I get the following errors.

java.lang.Exception: Cannot parse the output since it has an error. Error = ReasonCode = conflictCRVAP0049E (internal-error):  Cannot instantiate protocol provider: cqjnilinuxproxy (Not found in java.library.path) 
  ...java.lang.reflect.InvocationTargetException:

I followed the technote https://www-304.ibm.com/support/docview.wss?uid=swg21515079 - "An exception occurs on 64-bit WebSphere servers when running reports from ClearQuest data sources that require the Java Native Interface (JNI).

As suggested, WAS 32-bit was installed instead on 64 bit. But the error still occurs. Can you please let me know where this library is or what is going wrong?

Thanks, Aarthi

Answer 1

The ClearQuest libraries and jars need to be placed on the path so WebSphere can pick them up. Did you source cq_setup.csh prior to starting the WebSphere profile? You would need to source cq_setup.csh and then start the profile in the same shell.
