I have a sample application I am using to learn EJB 3.0. I am having a problem accessing EJB 3.0 beans from an EJB 2.1 session bean. I can not get an EntityManagerFactory. I need an EntityManager to perform an EJB 3.0 finder from the 2.1 Session bean. I am using JBoss 4.2 CR2. Using EJB 3.0 session and entity Beans together is not a problem. What else needs to be done?
Here is the error I am getting from the EntityManagerFactory creation line. 10:52:50,799 INFO [SettingsFactory] Default entity-mode: pojo 10:52:50,799 INFO [SettingsFactory] Named query checking : enabled 10:52:50,799 INFO [SessionFactoryImpl] building session factory 10:52:50,815 INFO [SessionFactoryObjectFactory] Not binding factory to JNDI, no JNDI name configured 10:52:50,815 ERROR [LogInterceptor] RuntimeException in method: public abstract java.util.TreeSet com.ejb.UserManager.retrieveMessages(java.lang.String) throws java.lang.Exception,java.rmi.RemoteException: javax.persistence.PersistenceException: org.hibernate.HibernateException: The ch osen transaction strategy requires access to the JTA TransactionManager at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Con figuration.java:720) // Example of getting EJB 3.0 beans from EJB 2.1 Session Bean. public List findPosts(String userLogin) throws Exception { HashMap map = new HashMap(); InitialContext initialContext = new InitialContext(); EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("imEjb30", map); EntityManager entityManager = entityManagerFactory.createEntityManager(); entityManagerFactory.close(); Query query = entityManager.createNamedQuery("findPosts"); query.setParameter(0, 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=4043950#4043950 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4043950 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
