Yes, I saw that later.

Doesn't make any sense to me. What does wanting to be a CORBA client
have to do with JBoss supporting CORBA?

Are you talking about having an MBean that binds the ORB into JNDI? I can
see how that would be useful.

I have to admit that you lose me at this point. I will leave this part
of the discussion to people who know about such things.

Or did you mean "seamless"?
Are you saying that we should propagate the transaction and security
contexts directly over the IIOP invocation rather than going through
the JCA interfaces? That makes sense for CORBA services that are aware
of such things, in fact it makes a lot of sense.
For CORBA services that are simply a way of exposing some external
legacy system the JCA approach would make more sense.

I can see this turning into an involved technical thread where the
original poster is left without a solution to his immediate problem.
Andreas - please do reply with an exact description of what you're doing
and what's going wrong.
Toby.
