With 5.0.x:
You can't use the CGI servlet. You would need to write your own
servlet that wraps the .exe using java.lang.Runtime.exec()
should provide some pointers on how to wrap exec() (search the source
for "exec" and remember that most of the CGIServlet is unnecessary for
what you want to do.

With 5.5.x:
You *might* have some luck setting the new executable init parameter.
I would try "" or "cmd".
