Did the Naming Service start up successfully?

> Run main method above and get "org.omg.CORBA.INITIALIZE: Could not create server socket (4689): java.net.BindException: Address already in use: JVM_Bind" error on "org.omg.CORBA.Object rootPOA = orb.resolve_initial_references("RootPOA");"

What command line options did you provide to the demo server with the
above main method?  In particular, did you provide a different port
number than 4689 to the -DOAPort option?

If the Naming Service is up listening on port 4689, you can't start
another server and have it try to listen on the same port number on the
same host.  Make sure you try a different port number for OAPort for the
demo server.
