When I try http://my_web_server/abc, it shows "HTTP 400-Bad Request"
BUT when I try http://my_web_server/pqr, it shows "HTTP 404 - File Not Found"
BUT when I try http://my_web_server, it works fine...which means that APACHE IS NOT SENDING THE REQUEST to TOMCAT....wonder why.
I've added workers.properties in my conf directory on Web Server. I also have MOD_JK.CONF file there.
-------------------- WORKERS.PROPERTIES -------------------- worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=102.103.103.1 #the above is IP of my App Server worker.ajp13.type=ajp13
-------------------- mod_jk.conf -------------------- Include "conf/mod_jk.conf" JkWorkersFile "conf/workers.properties" Include "conf/mod_jk.conf" JkLogFile "logs/mod_jk.log" JkLogLevel debug JkMount /examples ajp13 JkMount /examples/* ajp13 JkMount /abc ajp13 JkMount /abc/* ajp13

Your workers.properties should be on your webserver where apache is located. I typically place the workers.properties in the same directory where httpd.conf is located.
workers.properties is needed for mod_jk so it makes sense that it needs to be in the same machine where mod_jk and apache are installed. At least far as I know anyways. Sometimes apache has a difficult time finding it. I have used this line to tell apache where to find the workers.properties. You might try
including a line like this in your apache configuration file:
<IfModule mod_jk.c> JkSet config.file /etc/apache2/conf/workers.properties Include /etc/apache2/conf/mod_jk2.conf </IfModule>
If anyone else has anything to add to this or correct me on, please feel free because I am still learning to, but then again who isn't??
I hope that helps.

Thanks Randall for your reply... appreciate that!
My MOD_JK.CONF file is AUTOGENERATED on my AppServer. I start my App Server
FIRST which AUTOGENERATES "mod_jk.conf" file. So, how can I reference this
file on my HTTPD.CONF ("Include conf/mod_jk.conf") - which is indeed located
on a different machine?Where should I place my workers.properties? should it be on App Server or Web Server?
Should I first start App Server or Web Server or it does'nt matter?
In my HTTPD.CONF I have different mount points (example 'abc') so when I type http://IPADDRESS/abc it shows "HTTP 400 Bad Request" on my browser Howevere, when I type http://IPADDRESS/lmn it shows "HTTP 404 Page Not Found" (Note: lmn is not added a JKMount in my Httpd.conf)
My MOD_JK.log file shows it added all the JKMounts. My ACCESS_LOG file shows: [23/Mar/2004:08:44:05 -0700] "GET /abc HTTP/1.1" 400 0 [23/Mar/2004:08:50:24 -0700] "GET /lmn HTTP/1.1" 404 301
My ERROR_LOG file shows: [Tue Mar 23 08:41:46 2004] [notice] Apache/2.0.47 (Unix) mod_jk/1.2.2 configured -- resuming normal operations
Any related information on above is appreciated.
THANKS again!

I would leave your httpd.conf file the same as you have it shown below. I would also confirm in you logs that everything is working ok. However, Apache should not even startup if the included configuration file, mod_jk.conf is not present.
------------------------------ httpd.conf (on Web Server) ------------------------------ LoadModule jk_module modules/mod_jk.so ServerName xyz.com
Include conf/mod_jk.conf
JkWorkersFile "conf/workers.properties" JkLogFile "logs/mod_jk.log"
JkLogLevel debug
JkMount /examples ajp13 JkMount /examples/* ajp13
The trick here is to make some changes to your workers.properties in order to connect to another box. It looks as if your are trying to configure a load balancer. If you are connecting to only one instance of tomcat this is not necessary. Also you need to look in your server.xml and see that you have the coyote connector running on port 8009. I would exclude the line: worker.ajp13.lbfactor=5 from this configuration. Besides, you have not defined a worker for load balancer, so i believe this line is not necessary. I would probably write your workers.properties files the following way:
------------------------------------ workers.properties (on Web Server) ------------------------------------
workers.CATALINA_HOME=/usr/local/tomcat4 workers.java_home=$(JAVA_HOME) ps=/
worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=101.102.103.104 #above is IP address of abc.com worker.ajp13.type=ajp13 #Remove the following line. #worker.ajp13.lbfactor=5
I am going to send you my workers.properties for reference. IF AND ONLY IF you do configure a load balancer, then make sure in your server.xml to change following line from: <Engine name="Standalone" defaultHost="localhost" debug="0">
to
<Engine name="Standalone" defaultHost="localhost" debug="0" jvmRoute="worker2" > This is necessary for load balancing. The value of jvmRoute should be equal to the worker that you want to connect to that particular instance of tomcat.

SUBJECT: Apache+Tomcat + MOD_JK on different machine
I am using Apache 2.0.47 and Tomcat 4.1.27 on my SuSE Linux. I had configured my mod_jk and it works just great! (My Web and App Server were on same box)
Now I have a Web Server and App Server on a different box and was wondering what changes do I have to make to "MOD_JK" for the Integration to work.
My old settings were: ---------- httpd.conf ---------- LoadModule jk_module modules/mod_jk.so ServerName abc.com
Include /usr/local/tomcat4/conf/auto/mod_jk.conf
JkWorkersFile "/usr/local/apa2047/conf/workers.properties" JkLogFile "/usr/local/apa2047/logs/mod_jk.log"
JkLogLevel debug
JkMount /examples ajp13 JkMount /examples/* ajp13
-------------------- workers.properties --------------------
workers.CATALINA_HOME=/usr/local/tomcat4 workers.java_home=$(JAVA_HOME) ps=/
worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=101.102.103.104 #above is IP address of abc.com worker.ajp13.type=ajp13 worker.ajp13.lbfactor=5
Now that I have both APACHE and TOMCAT on DIFFERENT Boxes, I was wondering what changes do I have to make for the above to work.
My Web Server is "xyz.com" and my App Server is "abc.com". I have mod_jk configured in my Web Server.
My new HTTPD.CONF file is: My NEW settings are: ------------------------------ httpd.conf (on Web Server) ------------------------------ LoadModule jk_module modules/mod_jk.so ServerName xyz.com
Include conf/mod_jk.conf
JkWorkersFile "conf/workers.properties" JkLogFile "logs/mod_jk.log"
JkLogLevel debug
JkMount /examples ajp13 JkMount /examples/* ajp13
------------------------------------ workers.properties (on Web Server) ------------------------------------
workers.CATALINA_HOME=/usr/local/tomcat4 workers.java_home=$(JAVA_HOME) ps=/
worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=101.102.103.104 #above is IP address of abc.com worker.ajp13.type=ajp13 worker.ajp13.lbfactor=5
