Folks- I'm trying (for the past 2+ weeks) to make a hello world type application work with this environment:
Websphere 6.1 (EJB 3 Feature pack)
Hibernate 3.5.3
Rational Application Developer (RAD) 7.5
I keep getting the following error:
Code:
[11/18/10 13:36:49:193 EST] 00000027 JPAPUnitInfo E CWWJP0009E: The server cannot create an EntityManangerFactory factory for the TestPersistenceUnit persistent unit from the org.hibernate.ejb.HibernatePersistence provider in file:/C:/ws_workspace/HibernateWAS_EJB/ejbModule/ module.
Followed by this exception:
Code:
