Apache and Tomcat together on the same port?

Hi Friends. We have CetOS 5.5, Im working on setting a server up, that is supposed to be able to parse html, JSP,CGI, SWf, JPEG, png. I'm actually quite unexperienced in the use of Tomcat and Apache, since Ive always been working under an Windows platform, along with IIS. The problem for me when Im setting Tomcat up is that I cant get it to co-work with Apache, so that the regular apache mounted directories (/var/lib/apache/htdocs/) can parse JSP. I would have to connect to port 8080 first, then put my JSP pages under the Tomcat root directories. So, what I would like some help with is: How do I get Apache and Tomcat to work together by any connector (on the regular port 80)? All help appreciated!
