Sun's ORB isn't promised to be complient as far as I know. At least it
doesn't work as a server end, I think. I've been using JacORB 1.3.30 and
they play nicely (although there were some problems way back with R7B-0/1,
with marshalling) together. Now I'm using P8A (Orber 3.2.9) and happy with

Are you quite sure, you want to use Sun's ORB as it doesn't implement POA
and such compliantly? There's the JacORB (www.jacorb.org) and OpenORB
(www.openorb.org) that both are open source.
I might be wrong about the Sun's latest ORB, though.
