But writing a RPG app that talks servelet language is probably harder
than writing a java app that listens for basic requests.

Another option is to use data queues to transfer the requests ... simply
create a keyed data queue based on client IP address, have the webfaced
app add the request to the data queue, and have the java server
application (running on the client PC) simply wait on the data queue.
No socket coding required on either side.

IMHO, Tomcat is overkill in just about any client application ...
although I know it's used by a few client applications.

The client registers itself on the server and simply polls for activity.
  It doesn't broadcast it's IP, because 9 times out of 10 the remote
system isn't exposed on the internet.  The remote PC is a client that
connects to the remote server.
