Re: AJP 1.3 Connector
I'll continue to top-post, since you do. (Note that this is not the most logical way to have a conversation; it is easier when questions and responses follow a logical top-down order). Summary : - your Apache httpd configuration looks OK - your Tomcat AJP Connector looks OK - you can connect with a browser to the HTTP port of Tomcat, and with the URI /, you get the Tomcat homepage - you can ping the Tomcat server from the Apache httpd server - from the Apache httpd server, you can telnet to port 8009 of the Tomcat server - if you remove the JkMount directive from the Apache httpd configuration, you get the expected Apache httpd page - if you insert the JkMount directive, you get a message saying that Tomcat cannot be reached ... Obviously, something is wrong in the above list. If, from the command-line on the Apache httpd host, you can establish a TCP connection to the Tomcat host on port 8009 using telnet, then there is no immediate reason why mod_jk should not be able to do the same. Unless mod_jk is trying to connect to some other host than the one running Tomcat. The thing which causes a bit of doubt there, is that in your workers.properties file, you use the hostname server2.ourlab.com for Tomcat, while in all your other checks and messages, you use the hostname tomcatappserver. Is this just a matter of typing and censoring, or are these really two different names ? Or are they really two different hosts ? That they /should/ be the same host, does not necessarily mean that they /are/. Can you confirm that using the /same/ hostname in your workers.properties file and in your ping and telnet tests, everything goes as you have described it so far ? Note that you can also use the JkLogFile and JkLogLevel directives, to get more explicit error messages from mod_jk. But seen the above, it would probably just tell you that it cannot connect to server2. Troy-McKoy, Vickie wrote: Yes.

Re: AJP 1.3 Connector
I'm having doubts that mod_jk is actually loading. You say httpd.conf contains this line: LoadModule jk_module modules/mod_jk.so Unless you have a 'modules' directory under your ServerRoot that line should probably be /usr/local/lib/apache/mod_jk.so or something similar. Try this command and see what it turns up: find /usr -name mod_jk.so Use the full path in the LoadModule directive and force httpd to reload its config.

Thank you all for your responses; but my issue was in my testing. My configuration was fine; however, I was testing in my browser using the wrong port number. Thanks again...

Try the following : From the Apache httpd server (command-line), 1) enter : ping server2.ourlab.com If you get regular messages showing that the ping packets are being answered, it's fine. If you get error messages, then you have a basic network problem accessing server2.ourlab.com from your Apache host.
