Question on Linux Tomcat Apache Server and Port Redirection for a robotics site

This question requires knowledge of Linux Apache Tomcat Server.

I have a website with domain name for instance: www.robotronics.org
However this site is only for HTML and Javascript.

I have a Java J2EE site on the same domain name but you can't get to it unless you type the port:
http://www.robotronics.org:9080/Robotronics

How can I get the domain name www.robotronics.org to point to the Java J2EE site without having to type in the port 9080 and the directory Robotronics?

I found one site that gives some ideas on how to do it -->
http://rimuhosting.com/mod_jk2_and_mod_proxy_ajp.jsp#mod_proxy

Tomcat version 5.5 and Apache HTTP Server 2.2.

Thank you,

Never mind, my question was answered from a different forum.
