[omniORB] incoming LOCATE_REQUEST, how to satisfy it

Orbix's bind is a proprietary extension to CORBA. It will not work
with omniORB. You could try to second-guess what Orbix is trying to
do, but that isn't very pleasant. Orbix is inventing an object key, in
the hope that it is the correct thing. It isn't.

No. LOCATE_REQUEST simply asks the question "does the object with this
key exist?"  Orbix has made the key up, so omniORB answers "no". If
Orbix was using a valid key extracted from an omniORB IOR, omniORB
would answer "yes".

The only proper solution is to steer clear of proprietary extensions
to CORBA.

Cheers,

Duncan.
