[jboss-user] [EJB/JBoss] - Problem with transaction demarcation

[moksha2007]

Using jboss 4.0.5; a callback timer method on a stateless bean with transaction attribute REQUIRED_NEW does not seem to 'isolate' the transaction when called concurrently. A org.hibernate.StaleStateException occurs and the whole thing is rolled back.


  | @Timeout
  | @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
  | public void handleTimeout(Timer timer) {
  | // pseudo code:
  | // find obj (called on a different session bean with default settings)
  | // if found delete object
  | // The delete causes the stalestate when the entire batch is committed
  | }
  | 

According to the EJB3.0 specifiation the situation above should work, but it isn't unless I am doing things wrong. Any suggestions? Thanks in advance!
