8080 sounds like the default port for EPG. if you are using listener then your port should be the one of your webserver.
if you are using apex listener 2.1 then Vishal's blog: Installing SSL enabled APEX 4.1 with development environment and APEX Listener on Weblogic and standalone can be helpful. If you are on listener 2.2 then the process of installation is a little different. the process of installing apex however is the same
