Hi,

I am writing a portion of a J2EE application and would like to perform asynchronous processing. Following are some questions i have:

How does JMS process message, queue and Message-Driven-Beans? I mean when a message is send to a queue, how does it know which MDB should be receiving the message?

I am using JBoss and WebLogic App servers which has JMS Under normal circumtances, is it all right to use the default queue that comes with

the JMSProvider (i.e. the application server in this case)? Or should we write some other codes for create queue?

In terms of design, should one MDB only performs a single function? The reason for this is that a MDB seems to only have a single 'onMessage' method?

The following is what my application tries to achieve: Servlet will call a method in a StatelessSessionBean. SessionBean perform first some

processing. And since part of the process does not require to be done at the same time, i would like it to happen asynchronously. I actually

intend to have that part of the processing happens in an MDB. Is that the correct way to use JMS & MDB? How else could i perform asynchronous processing?

Thanks,
