8.5.0.1: WebSphere Application Server V8.5 Fix Pack 1
8.5.0.2: WebSphere Application Server V8.5 Fix Pack 2

APAR status

• Closed as program error.

Error description

• When JPA persistence units are defined in a persistence.xml
  contained in a jar file within the /lib directory of a WAR
  file, the persistence units cannot be found by the
  application. The symptom is that dependency injection of the
  EntityManager or EntityManagerFactory will fail similar to the
  following:

  The symptom is that dependency injection of the EntityManager
  or EntityManagerFactory will fail similar to the following:
  [6/11/12 14:38:21:565 CDT] 0000003b
  com.ibm.ws.jpa.management.JPAApplInfo                        E
  CWWJP0029E: The server cannot find the MyPU
  persistence unit in the MyAppModule module and the
  MY_APP application.

  javax.persistence.EntityManagerFactory for the null component

  application cannot be resolved.
  

Problem conclusion

• The product code was incorrectly setting the persistence unit
  archive name to that of the fragment jar rather than the
  name of the WAR that contains it.  This has been corrected.
