I tried getting omniORB working under BCB3 awhile back.  I ran into one =
problem
after another ... compiler bugs ... work around one, then the next one =
popped
up.  Borland tech support confirmed all but one of my reported bugs as =
bugs;
the one they didn't confirm they said they could not repeat.  I haven't =
gotten
back to them on this one yet.

The bad news ... I never got it working, after spending a lot of time on =
it.
The client changed project specs which led to my being able to avoid =
needing
CORBA for the BCB3 app.  The good news ... I'm now using omniORB quite
successfully.  Basically, the architecture was to have a CORBA server =
running
under ETS-Kernel (a realtime OS);  the BCB3 app would be the CORBA =
client,
running under NT.  The client then said they needed to be able to write =
Q&D apps
in Visual Basic;  at least back then, there were no good CORBA solutions =
for VB,
but COM was built in.  So I wrote a "mediator" to run under NT;  this is =
a COM
server & CORBA client;  apps talk to it via COM;  it translates the calls=
 to
CORBA to communicate with the ETS app.  Writing VB apps to deal with this=
 COM
interface is easy.  Likewise, it's fairly easy to use BCB3 to act as a =
COM
client ... actually, the coding is easy ... but figuring out how was a =
real bear
... the documentation is either awful or non-existent!

So, I've got things working.  Unfortunately, it doesn't help you with =
your
problem!
