How can I use getLocalPort to get backend port instead of the front httpd port?

Solution Unverified - Updated -

Issue

  • Having a test on EAP to make sure which port does the http request come from, http connector on 8080, or ajp on 8009. And I take mod_jk/mod_cluster on apache httpd as frontend. The httpd listen on 80.
  • In my servlet I try to use getServerPort() or getRemotePort(), but all the result is 80. The getLocalPort() is 0 or -1. Is there someway to get the correct port number?

Environment

  • JBoss Enterprise Application Platform (EAP)
    • 4.3
    • 5
