apache 2.0.45/tomcat 4.1.24 mod_jk trouble

Hello,

I've been trying to integrate apache and tomcat for a while, and I 
cannot seem to make it work.  I'm using the following versions on 
Redhat 8:

1.  Apache 2.0.45 compiled from source
2.  Tomcat 4.1.24
3.  mod_jk.so

For Apache:
I've added the mod_jk LoadModule calls to httpd.conf, and included the 
auto-conf file tomcat generates.

For Tomcat:
I've also edited server.xml to add listeners for the server and host.  
The auto-conf file is generated and looks to be complete.  There are 
several sections for creating the Apache Alias directives, etc.  I have 
a workers.properties file in /usr/local/tomcat/conf/jk.

Accessing /examples on port 8080 works fine.  I get a 404 "File Not 
Found" error when I try to access /examples on port 80.  It appears 
that Apache is not properly sourcing the auto-conf file (Include 
directive).  If I add a static alias in httpd.conf, I can reference 
static pages in /usr/local/tomcat, but servlet execution is not 
processed by Tomcat.  The two do not appear to be talking to each other.

I cannot find any indications from the logs for both applications as to 
what th eproblem may be.  Thanks in advance for any assistance.

nmap reports:

80/tcp     open        http
8009/tcp   open        ajp13
8080/tcp   open        http-proxy


A portion of my auto-conf file is:

  # Static files
     Alias /examples "/usr/local/tomcat/webapps/examples"

     <Directory "/usr/local/tomcat/webapps/examples">
         Options Indexes FollowSymLinks
         DirectoryIndex index.html index.htm index.jsp
     </Directory>


     # Deny direct access to WEB-INF and META-INF
     #
     <Location "/examples/WEB-INF/*">
         AllowOverride None
         deny from all
     </Location>

     <Location "/examples/META-INF/*">
         AllowOverride None
         deny from all
     </Location>

     JkMount /examples/jsp/security/protected/j_security_check  ajp13
     JkMount /examples/snoop  ajp13
     JkMount /examples/servlet/*  ajp13

Hi,

Sorry to chip in this late in the thread but if you running on a Unix box
have your tried tracing the process (Using something like the Solaris
truss command).  Process tracing has got me out of no end of sticky
situations like this.

The trace output will show you exactly the file that is trying to be
opened.

Cheers - Steve

No, mod_jk is all you need.  I am stumped.

Clay,

I think Justin is probably right. I had a lot of trouble with compiling 
mod_jk as well as mod_jk2. In fact, I still only use mod_jk-2.0.42 
(mod_jk) binary with my RedHat 7.3 setup.

There are some strange things with compiling mod_jk, such as compiling it 
always seemed to give drastically different filesizes compared to the 
binaries you can download.

If you're interested my installation setup is explained at:
http://daydream.stanford.edu/tomcat/install_web_services.html
(RH 7.3 Linux + updates/Kernel 2.4.20/jdk1.4.1_01)

I don't know what thread support is like for java in RH8.0 but, do you do
set this environment variable in your tomcat startup script?

export LD_KERNEL_ASSUME="2.2.5"
