Re: Distribued JOTM transaction between 2 jonasses

Hi Son Tung,

If i understood correctly, the behavior is normal as there're two 
different transactions when the requests goes across queues or topics :
/Transaction T1)/ is about the request processing in WebAp1. This 
transaction puts information in db and creates a message in the joram2's 
queue. This transactions is finishing at this point.
/Transaction T2) /is about the message processing (onMethod()). I'm not 
sure where is located this code (likely WebAp2).

If T2 rollbacks, it doesn't cause a rollback for T1 !

Regards
