We have a client want their web application to be run on Apache Web server with tomcat as a middle tier. I need to report to my manager about this.
I have tried and successfully installed Apached and Apache Tomcat. Both works BUT I follow some document to connect Tomcat to Apache, it DOES NOT WORK.

Are there any installer I can use?
I go through the Apache document but it still does not work..I think I must miss somthing..


Let's say if I can connect Tomcat to Apache, where do I deploy my web application?
at the moment, my application is located $TOMCAT_HOMR/webappl/HR folder.

I dont know how it work.

Please help

The version i use for Apache Server is Apache 2.0.53 (win)
Apache Tomcat 5.59

Here's a (minimal) configuration example.
It dispatches all requests for the 'examples' context
to Tomcat.
My setup is Apache 1.3.x/Tomcat 4.0.x on RH7.2. The
example should also be valid for your setup.

1. In httpd.conf, tell Apache to load the module:
LoadModule jk_module modules/mod_jk.so

2. In httpd.conf, configure mod_jk:
JkWorkersFile /etc/httpd/conf/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:$S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMount /examples/* worker1

3. Configure workers for mod_jk in


4. In server.xml, configure Tomcat to talk to mod_jk:
<Service name="Tomcat-Standalone">
   <!-- this is the HTTP connector which was configured
        in the server.xml that came with Tomcat
  <Connector className="org.apache.catalina........ />

  <!-- This makes Tomcat talk to mod_jk -->
  <Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
             address="" />


If you don't want to access Tomcat directly via HTTP, you
can comment out the entry for the HttpConnector.

After a restart of Tomcat and Apache, Apache should
dispatch requests for the 'examples' context to Tomcat.

port 9009 is the internal port where web server (apache) and application server (tomcat) comunicate. so to answer your question: 9009 is tomcat's listen port is localhost where to connect on 9009, for security reason this should always be localhost ( which is not accessable from anywhere else (assuming apache and tomcat on same computer)
