This works if the PERL script is actually a CGI. If it's a standalone app, see
below.

Generally, RequestDispatcher is used to access other servlets and JSPs in the
same servlet context, not external apps.

The most common mechanism for executing separate applications in your server's
OS (PERL or not makes no difference) is to use the java.lang.Runtime class's
facilities to start an external process and connect to it's input and ouput
channels. There is an example of this in the Java Language Tutorial
(http://java.sun.com/docs/books/tutorial) as well as other places.
