With omniORB you would use the options
-ORBendPoint to tell the orb to listen (and publish) only on this 
endpoint, -ORBendPointPublish to tell the orb to publish only this 
endpoint (but listen on all)
and -ORBendPointNoPublish to specifically not publish an endpoint

I have never worked with a JAVA ORB, but I would guess there should be 
some similar options ...
