Tomcat's HTTP server is not made to handle high traffic volumes where Apache is. You can use mod_jk to integrate Apache and Tomcat so that Apache serves up all the static content (HTML, graphics, etc) and passes control to Tomcat when a JSP is requested. Apache and Tomcat can run on the same machine or different machines. I have Apache running in a DMZ and talking to a Tomcat machine behind the firewall.
