It looks like you are throwing an exception in your server code that ***has
not*** been defined in your IDL interface. This is why the ORB on the
server side tell the client this is an UNKNOWN exception!

To use your own exception, define it in the IDL. Have a look at the IDL
syntax to find out how to do this.
