This is the best place to post.

Not yet AFAIK - though modifying the Messenger.xml config file a little and
it should work fine with MQSeries - if you get it working let us know and we
can add the MQ config file to CVS. We've already got config files for
JBossMQ, SpiritWave and AshnaMQ.

Should be fine. Though if you're building a mostly EJB based system then
maybe MDBs might help - its worth taking a look at them. If you can't use
MDBs for any reason then Messenger is a great (simple) alternative without
requiring an EJB2.0 container - it'll work just fine in Tomcat.

No I think you're certainly barking up the right tree. Messenger should make
it a little easier to work with JMS and if you're not using MDBs then
Messenger also provides a JMS 'application server' that can be deployed in
any Servlet engine, such as Websphere, to manage your subscriptions. So it
should be a good fit.
