404 error with mod_jk

Michael Powe <michael@xxxxxxxxxxxx> · Tue, 13 Jul 2010 11:37:14 -0400

Hello,

I have installed mod_jk (current version built locally) in IBM httpd
(IBM_HTTP_Server/6.0.2 Apache/2.0.47 (Unix) mod_jk/1.2.30 Server at
localhost Port 80).

I used the autoconfig option in tomcat to build the mod_jk.conf file
and added an include for it to httpd.conf.

I'm trying to configure this to work with virtual host in Apache.

Include /usr/share/tomcat6/conf/auto/mod_jk.conf

Contents of this file:

<IfModule !mod_jk.c>
  LoadModule jk_module "/opt/IBMIHS/modules/mod_jk.so"
</IfModule>

<VirtualHost localhost>
    ServerName localhost

    JkMount /manager ajp13
    JkMount /manager/* ajp13

    JkMount /helloworld ajp13
    JkMount /helloworld/* ajp13

    JkMount /docs ajp13
    JkMount /docs/* ajp13

    JkMount /host-manager ajp13
    JkMount /host-manager/* ajp13

    JkMount /TlTaggerTest ajp13
    JkMount /TlTaggerTest/* ajp13
</VirtualHost>

"JSESSIONID=CD3138FAB2C9059650B395B15B8BA3EA"

If I go to the page http://localhost:8080/TlTaggerTest/target.jsp, the
page displays.  Only if I go through port 80, the 404 is generated in
Apache.

mod_jk.log entries:

Thus, it appears to me that mod_jk is doing is job, and yet the "page
not found" error is generated.  Yet, tomcat finds the page if I go
through port 8080. I followed first the instructions for "quick start"
in the tomcat docs and then followed up with other accounts of setting
this up.

Also, FWIW, if I go to the page via port 8080, then afterward the
jsessionid shows up in the apache log, even though I'm going through
port 80.

Additionally, I may add that I used ProxyPass first to connect the two
servers and that did work.  But, I need mod_jk so that Apache will
handle the requests rather than just forward them.

Any help in troubleshooting and resolving this would be much
appreciated. I need to have this working in order to test a new Apache
module (which is what I'm _really_ supposed to be working on!)

Thanks.
