Thanks Everyone, the JIRA ticket can be closed. Thanks jaikiran! that worked when I moved the persistence.xml to the META-INF within the EJB jar. I also found that with my current structure of having persistence.xml at the top level META-INF within the ear, it works when I have the unitName for the @PersistenceContext annotation. Eg: @PersistenceContext(unitName=PERSISTENCE_UNIT_NAME) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4202576#...
