You can use code (though I've never tried it yet); though one of the points
of Messenger is that the JMS configuration becomes a deployment option
rather than inside your application code. Though I don't see any reason why
you can't use Java code if you wish.

Right now the MessengerManager is a little container of Messenger instances
which are looked up by name. You could manually create a MessengerManager
and register Messenger instances as you wish - or just use your own
Messenger directly and not bother with the MessengerManager class.

Putting Messenger.xml anywhere in the classpath will do the trick; or just
explicitly initialising Messenger in (say) a Servlet my getting the URL from
some location.

e.g. in a servlet you could do

    URL url = getServletContext().getResource("/WEB-INF/Messenger.xml");
    MessengerManager manager = MessengerManager.configure( url.toString() );
    ...

or do something similar in an EJB etc.


If you want to be able to hot deploy the servlet and ear independently, then
they should both have their own JMS connections & MessengerManager instance,
so that you can take down (say) the ear and the war keeps running etc.

Absolutely. There's a sample JBoss configuration file in src/conf
