Hi,

I'm doing a project on jBPM and JBoss Messaging. Right now I'm just trying to get an understanding of why you would use JBoss Messaging. Unfortunately the 1.4 User's Guide does not go into the basics.

I understand that you can send async messages to queues and topics, I don't quite understand exactly what these are but this is not the questions I want to ask, its more basic then that...

My question is...

Why would you use JBoss Messaging?
What real examples would it be useful for?
Are they used to invoke other processes? Any examples?

Your help would be greatly appreciated! :)
