Websphere HibernatePersistence incompatible with PersistenceProvider

Question

Websphere v8.5.5 supports JPA 2.0 out of the box.

I am trying to deploy a WAR to a Websphere v8.5.5 application server. My persistence.xml specifies org.hibern

Answer 1

The problem was hibernate-jpa-2.0-api-1.0.1.Final.jar.

My understanding of the linked articles was that I should be including this JAR with my application. However, by removing this JAR the class cast exception has gone away.

Answer 2

The only option (aside from not overriding javax.persistence) is to disable container-managed JPA altogether for this application. See the documentation in PM26361.
