Hello there, Is there a JIRA issue for the recursive error in JTATransactionFactory.getUserTransaction() in 3.3.1.GA or you want me to add one + patch? If the UserTransaction name is invalid, NamingException is thrown recursively by getUserTransaction() call (line 172) until the stack is full. You probably wanted to call getUserTransactionName() instead of getUserTransaction(). Cheers Ovidiu
