Mani,
Here's what you could do.
Set up a JMS queue.
Create an MDB which has the queue as its selected destination.
Write your MDB so that its 'onMessage' method never returns.
Send a single message to the queue.
Your MDB should now be always active trying to 'complete' processing
of the singleton message that you sent (the send must be once-only,
the message should never be received by a client or fully processed
by the MDB).
You are permitted to call session beans from an MDB.
