Never tried it in the way you've outlined. You can, however, store the EntityManager and EntityManagerFactory in JNDI and look up from there by putting the following in your persistence.xml: <property name="jboss.entity.manager.jndi.name" | value="java:/entityManager/yourName" /> | <property name="jboss.entity.manager.factory.jndi.name" | value="java:/entityManagerFactory/YourName" /> S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3992936#...
