[wildfly-dev] Handling @TransactionAttribute exceptions

Hello, I need to handle exception when either TransactionAttributeType.MANDATORY or TransactionAttributeType.NEVER requirement is not met. It is not a problem for MANDATORY, because EJBTransactionRequiredException is thrown. However, general EJBException exception is thrown if unexpected transaction was on the thread. I wanted to ask what is the best way to detect that EJBException was caused because of unnecessary transaction? Error code given by the exception is JBAS014163, but I am not sure if it is safe to rely on message codes... Thanks, Gytis
