[jboss-user] [EJB 3.0] - Bean Managed Transaction: No JTA transaction found

I am resorting to BMT due to the need to launch persistence operations in worker threads. I am using the BMT format as described here http://www.hibernate.org/hib_docs/entitymanager/reference/en/html/transac... So, I have | @PersistenceUnit EntityManagerFactory m_emf; | @Resource UserTransaction m_ut; | And my worker threads do the equivalent of | public Result call() { | EntityManager em = factory.createEntityManager(); | try { | | // do some work | ... | | m_ut.commit(); | } | catch (RuntimeException e) { | if (m_ut != null) m_ut.rollback(); | throw e; // or display error message | } | finally { | em.close(); | } | I observe that any entities I create aren't being written to the database. Looking in JBoss logs from the EntityManager creation point, I see: | 2008-05-24 12:39:10,911 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] Looking for a JTA transaction to join | 2008-05-24 12:39:10,911 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] No JTA transaction found | Also, When I look at what happens when I am creating and persisting entities, I see: | 2008-05-24 12:40:05,036 DEBUG [org.hibernate.event.def.AbstractSaveEventListener] delaying identity-insert due to no transaction in progress^M | Am I making some obvious mistake? Is launching persistent operations from separate threads not supported? Thanks. -Raj View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153175#...
