Hoiw about this:
http://docs.jboss.org/jbossmessaging/docs/userguide-1.4.5.GA/html/examples.html
You will need to download JBoss Messaging to get the examples, but you do not need to install it - JBoss AS 5.x comes with JBoss Messaging already installed.
I also have another resource, but it is not free. I can provide a URL if you are interested.
