jbpmDS is configured on WAS 7. Friends any ideas about the root cause?

I have configured my persistence.xml in the following way to resolve the issue :

Solution

<jta-data-source>java:comp/...</jta-data-source> does not work well with container-managed Hibernate JPA. WebSphere Application Server needs to call createContainerEntityManagerFactory prior to doing nearly everything else in the application because that call might register a ClassFileTransformer that needs to modify entity bytecodes.

Your options are:

  1. Remove the use of <jta-data-source>java:comp/...</jta-data-source> and use a JNDI name from the server namespace (e.g., <jta-data-source>jdbc/myds</jta-data-source>).

  2. Disable container-managed JPA for the application as described in APAR PM26361. (This APAR describes performance issues caused by the call to createContainerEntityManagerFactory during application start, but the property can also be used to avoid this problem.) Of course, disabling container-managed JPA means you can no longer use @PersistenceUnit/@PersistenceContext annotations or <persistence-unit-ref>/<persistence-context-ref>.

OTHER TIPS

It seems related with names of the datasources as this post said.. try that first and see if you get the second error: https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014210826

I agree with @bkail on this.
I was facing similar problem while running on WAS 7. Resolved it following the 1st option in the answer. 2nd option is not recommended since client uses the same server to host multiple applications.
In addition to that I also removed the jar file jbpm-test-5.4.0.Final.jar from EAR -> Deployment Assembly as well as WEB-INF/lib in the WAR Project. Otherwise it does not work with the first option only since Websphere detects a data source inside the jar.
