So I have a web application that runs on Tomcat, but I also have Apache running, so I can't forward Tomcat to use port 80, so now its just sitting at 8080. Is there anyway I can configure the two of them to kinda "work together" so if I put in http://app.domain.com/ it would go to the Tomcat application? Thanks!
Apache's Name-Based Virtual Host configuration will allow you to accomplish this fairly easily: set up a name-based vhost for your Tomcat app and configure it to use mod_jk to talk to Tomcat.
