I am using a WAS7 with a DB2 and I want to change the persistence provider from openjpa 1.2.2 (provided with WAS7) to hibernate 3.3.2.GA (the last JPA 1.0 implementation?).
But it doesnt work, I get following error:
Code:
Caused by: javax.ejb.EJBTransactionRolledbackException: nested exception is: javax.ejb.EJBException: Injection failure; nested exception is: java.lang.IllegalStateException: EntityManagerFactory has not been created for PU : PuId=ZWREar#ZWRService.jar#zwr+

at com.ibm.ws.jpa.management.JPAPUnitInfo.getEntityManagerFactory(JPAPUnitInfo.java:1352)
I can't make head or tail of it:

<property name="hibernate.transaction.manager_lookup_class"

</properties>
</persistence-unit>
</persistence>
Do I need really to declare a jta-data-source
and a property with a datasource?
Quote:
<jta-data-source>jdbc/asdf</jta-data-source>
Code:
<property name="hibernate.connection.datasource" value="
java:/comp/env/jdbc/asdf" />
Could someone tell me what I have to do that an alternative persistence provider works?
