I have seen a stack trace like this before. Aren't you using an older
JacORB version at the client side by any chance?
JBoss requires JacORB 1.4. Neither JacORB 1.3.X or 1.4.betaX will work.
JacORB 1.4 was not yet publicly available when we released JBoss 3.0,
which went out with an unofficial "sneak preview" of JacORB 1.4's
library (jacorb.jar).
Please use at the client side the jacorb.jar file in the JBoss 3.0
distribution. Or else get JacORB 1.4, which was just released.
(I didn't test the official JacORB 1.4 GA release with JBoss yet.
This is the first thing in my todo list. It should work, unless
there is some last minute surprise.)
Another thing: you should not need any CORBA code in your RMI/IIOP
clients. Unless you are doing more CORBA stuff, you can remove the
ORB.init() call from your RMI/IIOP clients. There is no need to set the
"java.naming.corba.orb" property before you construct an InitialContext.
The initial context factory and the provider URL are enough.
Let me know if the problem persists. I was away from this list for a
few days, but should be able to respond quicker now.
Best,
Francisco
