On a project last year, a team I was on built a CORBA-based distributed
event mechanism. We didn't base it on JMS, since that was just a twinkle
in somebody's eye. Instead we simply made a JavaBeans-style event
mechanism that was extended for additional event types, and used Support
classes that took care of all the ugly details (distribution, threads,
conversion to & from CORBA Any types, communication with an event broker
at such time as we needed one, whatever). The event producers &
consumers didn't have to know about that stuff. It wasn't a difficult
thing and was pretty successful. Project failed, though, so regrettably
I do not have access to any of the technology or even documentation.
In terms of WebLogic and JMS, I've been talking to them about that and
their next release (4.1) is due out "any day now" with JMS support. For
my money, I'd get ahold of them and see if/when you can get 4.1 access.
They have been explicitly holding off on JMS support before now because
they already had a workable event mechanism, and they didn't want to
start implementing a new one until the Sun spec stabilized more. There
are some things about their proprietary mechanism that I like, and I
hope they don't get lost in the switch to JMS.
