Nigel,
Very kind of you to respond. I hear you might know a thing or two about
JMS! ;-)
I'm happy to report that the source of my issues was chiefly, as you
suggest, in getting the WebSphere-specific bindings right. IBM's
documentation is formidable, in both positive and negative ways. It lays
out quite a bit of information about both the standard bindings and
non-standard bindings, but doesn't give a lot of help understanding in
which cases one applies vs. the other. Further, much of WebSphere's JMS JCA
and MDB related documentation assumes you're using either MQ or WebSphere's
internal messaging (with even more non-standard binding/notation!),
therefore the examples require some translation as well.
Once I sorted out the fact that <jmsActivationSpec> is the exclusive way to
specify the binding parameters in the server.xml, and sorted out the
non-standard notation in ibm-ejb-jar-bnd.xml, I was able to drive my
request-reply MDB via GenericJMSRA (and EMS) without issue.
As the steps for configuring for WebSphere Liberty Profile are a bit
different from those for JBoss, SJSAS/GlassFish, and even WebSphere "Full"
Profile, I will submit my configuration steps in a separate posting so they
can (I hope) be included in the site and/or SVN.
Thanks again for the thoughtful response.
Cheers,
Larry
