[jboss-user] [EJB 3.0] - My MdB receives the same message again and again

[schausson]

I'm currently setting up a MdB that is in charge of long-running processes : 
basically, when it receives a message, it might cause many objects (up to thousands) to be persisted in the database, which can last dozens of minutes in some cases.

When this process lasts less than 5 minutes (approximately), everything works fine.
When this process lasts more than 5 minutes, onMessage() is invoked again (with redelivery_count increase) and the previous processing stops without any warning/logs !

I first suspected that it was a transaction timeout issue, and added following annotations on the onMessage() method of the MdB :
	@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
	@TransactionTimeout(value=100000)

(I also tried to set a NOT_SUPPORTED transaction mode, but the entityManager (container  injected one) just failed to persist my object outside of any transactional context)

I also tried to remove the code that invoke the entityManager to isolate from DB issues.

Finally, it always behaves in the same manner and I couldn't figure out what I can change to make it work...

Any idea ?

Many thanks,

Sebastien
