Hey all, I also got this error when using the TransactionManager, which is about the same as the UserTransaction.
The problem was that I was using the the TM while it was still busy with another transaction, you have to check the status of the TM first. heres how I fixed it. | EntityManager EM = EMF.createEntityManager(); | TransactionManager TM = (TransactionManager)ctx.lookup("java:TransactionManager"); | boolean suspended = false; | Transaction t = null; | | if(TM.getStatus() == Status.STATUS_NO_TRANSACTION || TM.getStatus() == Status.STATUS_UNKNOWN) | { | TM.begin(); | EM.joinTransaction(); | } | if(TM.getStatus() == Status.STATUS_ACTIVE) | { | suspended = true; | t = TM.suspend(); | TM.begin(); | EM.joinTransaction(); | } | else | { | throw new Exception("Transaction status invalid: "+TM.getStatus()); | | } | | //Do Actual Work with DB | | EM.persist(Entity); | EM.flush(); | TM.commit(); | | if(suspended == true) | { | TM.resume(t); | } | | TM = null; | EM = null; | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4195868#4195868 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4195868 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
