I have a Message Producer that creates a QueueSession with AUTO_ACKNOWLEDGE as the acknowledgement mode.

I don't want to hold on to a MDB instance while waiting to re-transfer the file, and from what i have read, it isn't recommended to start threads in the EJB Container. I would like to do something like this:
onMessage
1: Determine message type,
2: Call the appropriate helper class/Session Bean, and
3: Return without waiting.
Can anyone help?
Also, can someone tell me when an AUTO_ACKNOWLEDGE message is actually acknowledged? Is it as soon as the message is retrieved, or when onMessage has completed successfully?
Thankyou!
