Error in connecting servant to ORB: ClassCast exception

Question

Hello,
I'm working on a software using CORBA. (i'm not sure to be on the good forum for this kind of problems)
Here is stacktrace:
Nov 3, 2008 12:07:35 PM com.sun.corba.se.impl.orb.ORBImpl connect
WARNING: "IOP02310202: (OBJ_ADAPTER) Error in connecting servant to ORB"

This happens for one user on any computer he uses.
I can't give you more code as it is part of something really big and i didn't manage to reproduce it.
Does someone as an idea of what can be the real cause ?
Thx
