Hi,
Problem Description:
Invoking methods on a CORBA server (C++) that uses omniORB 2.8 from
a java client (JDK 1.1.7)

Yes, args[0] is the IOR on the nameservice.

I have also tried the same thing passing to a java-client the IOR of my server
instance instead of the IOR of the NameService. In this way it works fine.
When I pass the IOR of the nameservice and then I try to narrow it to a
NamingContext I always get a null value.
Any suggestion?
cheers
