That looks fine to me.

Though I've never actually tried Messenger with JBossMQ, it should work fine
though. I've been thinking we should start committing to the project various
config files for different JMS configurations.

Mmm there's not much to go on here. Actually this is the wrapped exception
that is being reported - the underlying exception is inside the
JMSException.getLinkedException() method which isn't being displayed by the
program.

I've patched the code in the 3 sample programs, Caller, Producer, Consumer
to display the underlying exception, not the wrapped exception - which
should help. Also I've added the undelying exception discription to the
JMSException that gets thrown.

These changes are now in CVS so if you take another snapshot - or download
the next daily build and try run it again we should at least see the reason
for your problem! Then we can try fix it :)

Great!
