Seems I solved it, it was a problem with a "throw" clause.
The throw clause contained ::CORBA::SystemException only. I
assumed that then any ::CORBA::UserException and thus any self
defined exception would be included.

Now I made a test with TAO (which uses "throw" in the generated
servant base sources) and got a similar problem. I simply copied
all throw-clauses (were just 478 lines to change :() for all
prototypes and TAO was working.

With those fixed throw clauses Omni now also works. So it was
just a problem of the _impl-Sources.

Now I saw in omniORB4/CORBA_Exception.h that UserException is
/not/ a specialisation of SystemException.

BTW, I think (unless other ORBs should be supported), in general
the best is not to use the "throw" clause in C++ at all.

oki,
