Hi Kiran,
Container managed transactions and tx attribute REQUIRED are the
defaults in EJB 3.0 so you shouldn't have to configure anything. If
you do want to configure them explicitly the easiest way is to use
annotations. Just add @TransactionManagement(CONTAINER) at the message
driven bean class level and @TransactionAttribute(REQUIRED) to the
onMessage method.
