Need Help with Servlets & JSP Pages

I have had Apache2 setup on my home server, and I recently setup Tomcat 5 for my Java project. I would like to run Java Servlets and JSP pages. I used the tutorial found at http://ubuntuforums.org/showthread.php?t=219985.

The problem is, I don't want to run files located in the /var/lib/tomcat... directory. Can't I run the scripts from the user's public_html folder like other scripting languages? I searched the Internet for a solution with no luck.
