At the moment we don't support IIOP as a transport in the ESB, though of course it's there in the application server. CORBA is something that we've considered, but there hasn't been enough interest for it to push it up the priority list. Maybe you want to help :-)?
As for Orbacus, I'll have to take a look at that because the last time I used Orbacus was just before OOC was acquired by IONA.
Thanks for the prompt reply.
I guess without CORBA we wont be using JBossESB.
In case we do decide to go ahead with it I will let you know and I will definitely put my hand up for contributing to the CORBA component of ESB.
Thanks. We'll probably be looking to add CORBA support in the ESB 5 timeframe.
