JavaIdl client with omniNames?

To my knowlege, the answer is "no".JavaIDL's resolve_initial_references uses a
bootstraping protocol which is
specific to Sun's JavaIDL. It works only with JavaIDL servers and clients.

I checked CORBA 2.1 specs and it seems that they do not provide a standard way
of resolving
initial references.

So do I.

This cannot help because JavaIDL's ORBInitialPort is a port where JavaIDL's
bootstraping service(com/sun/CosNaming/BootstrapServer object) is expected to
be.
And for omniNames, the port in log file is the port where
org/omg/CosNaming/NamingContext
itself is available.

The only solution I know is to obtain IOR from onmiORB.cfg (java client can do
this via HTTP or FTP).
