I am trying to access IBM FileNet P8 V5 datastore from a servlet and need help in getting the WebSphere configuration correct.
I have a fresh install of FN P8 on a RedHat 7 server with IBM WebSphere.
I tried the example code given on https://www.ibm.com/support/knowledgecenter/en/SSNW2F_5.0.0/com.ibm.p8.ce.dev.ce.doc/ss_ecl_cews.htm
It works fine from a plain Java class; connects to the server and retrieves the datastore name.
I copied the code over to a servlet but getting the error: " com.filenet.api.exception.EngineRuntimeException: FNRCS0005E: SECURITY_INVALID_CREDENTIALS: Access to the Content Engine was not allowed because the Content Engine API library or the Web Service Interface (WSI) Listener could not find the required security context information. Expected credentials were not found in the security context"
As per the tutorial, I need to set the runtime environment. That's where I'm stuck at. I tried adding jaas.conf.WebSphere in via the WebSphere console in the JVM settings but am obviously not doing it correctly.

The application with the servlet is installed on the same server.
