This will fail in Servlet API 2.1, getServlet() is deprecated.
In 2.1 you have to find the servlet yourself, use Class.forName(),
etc.
The replacement for getServlet() is ResourceDispatcher(), but it can't
handle such usage ( and there is a good reason for this - security ).

Use an URL, pass whatever request you want ( use the "Java Servlet Programming"
for examples of
posting).
If you are using sessions - you are in trouble ( and if you find a solution
for that, please let me know - I had
no luck getting an answer to this question ).
