jacorb client cannot resolve naming contexts

Hello,
I'm trying to get my java client talking to a jacorb server.
I have compiled the client w/ jacorb.

Now, it fails in resolving the naming context with a Cannot Proceed
exception.

The same code fragment appears to run fine under visibroker.

Any clues here would be very appreciated!!

rootContext =
NamingContextHelper.narrow(orb.resolve_initial_references("NameService"));

 NameComponent[] ncName = new NameComponent[4];

                ncName[0] = new NameComponent();

                ncName[0].id = "A";

                ncName[0].kind = "akind";

                ncName[1] = new NameComponent();

                ncName[1].id = "B";

                ncName[1].kind = "bkind";

                ncName[2] = new NameComponent();

                ncName[2].id = "C";

                ncName[2].kind = "EInstance";

                ncName[3] = new NameComponent();

                ncName[3].id = "12.0";

                ncName[3].kind = "Version";

            log.info("About to get the child root  context ....");


  myFactory = myFactory_IHelper.narrow(rootContext.resolve(ncName ));

This last line is failing. What could be wrong??
