Parallel processing of JMS messages?

Is it possible to create a pool of Message Listeners or a Message Driven Beans to process messages from a JMS queue or topic in parallel ?

I am using JBoss and JBoss's JMS

Absolutely. I've done it with JMS queues to create a multi-server pool of listeners in order to process large numbers of transactions. You can use the Competing Consumers pattern. I used a modified one, since we needed to process messages in order within accounts. We used a lease mechanism to allocate servers to account number ranges, providing failover and scalability.

We were using Tibco's JMS provider, but it works with any JMS provider.

Yes, if the MDB pool size is greater than one, JBoss should create multiple MDBs to process the messages in parallel.
