I ended up using the InitialContext to lookup the EntityManagerFactory. Not sure if this is the correct way or not but it works. Below is the new code. // Example of getting EJB 3.0 beans from EJB 2.1 Session Bean. public List findPosts(String userLogin) throws Exception { InitialContext initialContext = new InitialContext(); Object obj = initialContext.lookup("java:/imEjb30Factory"); EntityManagerFactory entityManagerFactory = (EntityManagerFactory)obj; EntityManager entityManager = entityManagerFactory.createEntityManager(); Query query = entityManager.createNamedQuery("findPosts"); query.setParameter(1, userLogin); List list = query.setMaxResults(10).setFirstResult(0).getResultList(); return(list); } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043997#...
