Monte,
There doesn't seem to be a compelling reason to use a servlet in your
application since a browser doesn't seem to be involved. Have you
considered using RMI? It may be a more direct solution. You would just
invoke a class method on the server with an int as a parameter. The method
would then return an int.

Richard
