Request dispatchers were introduced in version 2.1 of the servlet API. If Websphere
supports that, you should be able to call:
getServletContext().getRequestDispatcher("/pathname");
to get a request dispatcher instance. Whether you can get a request dispatcher for a
CGI script on a different server is dependent on the engine you are using ... request
dispatchers are
designed to access other servlets in the same servlet context.

A way to tunnel to a CGI script (or even a static web page, for that matter) that
works on any servlet engine, or in any other Java application or applet, is to use a
URLConnection.
Essentially, you become the client of the CGI script's server, making an HTTP request
to it, and then processing the results that the script sends back as you see fit.
There's good examples
of using this class in the Java Language Tutorial:
