OpenJMS and EJB MDBs
A couple years ago I attempted to use OpenJMS to create a MDB container
system for OpenEJB. I couldn't do it because OpenJMS at that time did not
support JTA resource API - this predates J2EE Connectors 1.5. Does OpenJMS
support this now? Specifically can it act as a 2pc resource? If so, than
perhaps the best approach to building a MDB container is to create a J2EE
Connector for OpenJMS. That would allow it to be totally plugable rather
than tightly coupled - I figure that's the way we would go anyway, but I
wanted to raise the issue of OpenJMS not supporting (in the past) 2pc.

The OpenJMS folks (largely me :), are strapped
for time at the moment, but your wishlist is noted.
Of course, if anyone wants to contribute JCA support,
to OpenJMS, they're welcome.

Tim

Actually, I think all you need to do is to build a MDB container that supports J2EE
Connector Architecture 1.5 facilities for asynchronous messaging. If you build it
right, the MDB container would be capable of supporting any JMS implementation that
properly implemented J2CA 1.5. Not just JMS, you can support any async messaging
system like SMTP, SOAP, and what have you.
OpenJMS works and is available, so if those folks build a J2CA 1.5 adapter, then we
could just plug them into Geronimo and have support for JMS-based MDBs. I would
also, as mentioned before, like to do the same or something similar with an e-mail
system ... like James.

Hello Richard,
Is OpenJMS primary JMS implementation for Geronimo?
