/*             The "This actually works" CORBA Example:

use 

  idlj -fall cbtest.idl

to compile idl file (not java file!)

Compile all .java files

start orb with

  orbd -ORBInitialPort 10001

start server:  (assume same host as orb)

  java test1server -ORBInitialPort 10001

start client: (if on same machine as orbd)

  java test1client -ORBInitialPort 10001
