Thanks everyone, some more info:
1. Note that over the last week I've submitted to GlassFish forum here: http://www.java.net/forum/topic/glassfish/glassfish/need-help-glassfish-install-front-ended-apache2-modjk#comment-822040 to serverfault here: http://serverfault.com/questions/359218/mod-jk-log-error-message-what-does-it-hint-might-be-the-issue to stackoverflow here: http://stackoverflow.com/questions/9220969/access-web-container-through-apache-webserver-port-80-using-mod-jk but didn't get much feedback. I submitted here because I was hoping someone with mod_jk experience could interpret the log file lines below as to what it means, and brainstorm what could potentially be causing such an error. I don't know if the GlassFish folks would be as knowledgeable here. For example, if a socket connection is established and AJP transmission occurs, even though it's only one way, would GlassFish have to be listening for this to happen? Would GlassFish have to reply via AJP to establish a socket? That sort of thing. What does the log file tell us about the communication between Apache and GlassFish, and what does it not tell that we would need to know to pinpoint the problem, etc.? 2. Note that port 4850 is an administrator port open simply for web-console administration of GlassFish (it can also be accessed from command line). 3. Note that I can use netstat to verify tcp connection status ESTABLISHED in both directions (Apache to GlassFish, and GlassFish to Apache). ----- Original Message ----- From: "Pid *" <p...@pidster.com> To: "Tomcat Users List" <users@tomcat.apache.org> Sent: Saturday, February 11, 2012 4:10:54 PM Subject: Re: desperate for help to set up straightforward mod_jk connection between Apache2 webserver and web container On 12 Feb 2012, at 00:03, "modjkl...@comcast.net" <modjkl...@comcast.net> wrote: > Hi Pid, > > > 1.

As your minimal mod_jk config looks OK at first glance I'd suggest you need help from the Glassfish community. Or you could install Tomcat instead. p > 3.
