>From your source code, I guess you used bitronix. You have to make bitronix initialize it, and by this, bind java:comp/UserTransaction to the transaction manager, So, to do this: You should try: bitronix.tm.TransactionManagerServices.getTransactionManager().begin(); (actually, bitronix.tm.TransactionManagerServices.getTransactionManager() should do it)
