[omniORB] OmniORB and JAVAorb, trying to use corbaloc

[Brenneis, Steve]

I have only been able to get the corbaname URI to work with omniORB and the
JDK 1.4 ORB and I haven't seen any problems with an IOP version mismatch. As
far as I have tracked, the problem seems to be in the JDK ORB. As an
interesting side note, the JDK 1.3 ORB was documented as supporting the
corbaname/corbaloc URI's, but as Duncan pointed out, it didn't really work.
