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.hibernate.ejb.HibernatePersistence as the JPA provider.

I have also set the JPA properties:

jpaProperties.put("hibernate.transaction.factory_class", "org.hibernate.transaction.CMTTransactionFactory");
jpaProperties.put("hibernate.transaction.manager_lookup_class", "org.hibernate.transaction.WebSphereExtendedJTATransactionLookup");
jpaProperties.put("jta.UserTransaction", "java:comp/UserTransaction");

as outlined in this PDF presentation and in this IBM topic

My application is set to "Parent Last" class loading policy and I have included in the WEB-INF/lib directory the following JARs:

• hibernate-jpa-2.0-api-1.0.1.Final.jar
• hibernate-commons-annotations-4.0.2.Final.jar
• hibernate-core-4.2.5.Final.jar
• hibernate-entitymanager-4.2.5.Final.jar
• hibernate-envers-4.2.5.Final.jar

Despite all of this, I still get the following error on application startup:

[4/25/14 15:50:58:534 CDT] 0000007e JPAPUnitInfo  E   CWWJP0015E: An error occurred in the org.hibernate.ejb.HibernatePersistence persistence provider when it attempted to create the container entity manager factory for the fastPersistenceUnit persistence unit.

Does anyone have any idea how to get rid of this error?

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.
