I have a JBPM process that sends MEssages (communication control blocks) to a given MDB queue. these message are being translated when they are received by the bean.
My problematic is to consume messages one by one, in other words, when transaction 1 have finished, MDB must consume the next message in queue.
In normal execution, MDB open a new Transaction for each received message, so, I'm finishing with multiple concurrent sessions that may update the same data concurrently. And As a result, .... many times my data updates are lost ....
So, I have to organize message consommation by MDB
I hope being clear
