I have been trying to get the Service Desk Tomcat server to talk with the Apache ( 2.2.12) install on my Linux server by using mod_proxy_ajp. I have setup the proxy pass and the proxy reverse pass using the ajp protocol. The Tomcat server is running on port 8089 and when I point the proxy pass throughs to the port, it seems to respond prior to returning a 503 error. Has anyone been able to successfully get the Service Desk Tomcat server to communicate with an Apache server using either mod_proxy or mod_jk?
