The Jakarta Tomcat Connector mod_jk module is provided as a connector from Apache Tomcat source, Jetty (and obviously Tomcat) is fully compatible with this connector. This module is avaiable when you download the Tomcat source, but also is available for download separately, refer to the following URL for the proper version for your system.. Refer to http://tomcat.apache.org/download-connectors.cgi^{Image Removed} for the proper version for your system.

In addition to the mod_jk you will require a workers.properties file, also available with the Apache Tomcat source distribution. This properties file tells the mod_jk plugin how to connect to the Geronimo server. For a detailed explanation on all the available options for configuring the Jakarta Tomcat Connector visit the following URL:http://tomcat.apache.org/connectors-doc/config/workers.html^{Image Removed}.

Download the appropriate mod_jk for your platform from the Tomcat web site. For this particular example rename it to mod_jk.so and copy it into the <httpd_home>\modules directory. Download and extract the workers.properties from the Apache Tomcat source (alternatively, download it from the Attachments section) to the <httpd_home>\conf directory.

Edit the httpd.conf file located in the <httpd_home>\conf directory to load the Jakarta Tomcat Connector mod_jk module. Add the following lines at the end of the httpd.conf file.

LoadModule jk_module modules/mod_jk.so			
# Loads the Jakarta Tomcat Connector module

JkWorkersFile <httpd_home>\conf\workers.properties
# Tells the module the location of the workers.properties file

JkLogFile     <httpd_home>\logs\mod_jk.log
# Specifies the location for this module's specific log file

JkLogLevel    info
# Sets the module's log level to info

JkMount /console/* ajp13
# Sets a mount point from a context to a Tomcat worker. In this case will allow access (forward the request) to the console.

Configure workers.properties

The workers.properties, among other things, tells the HTTPd where the Geronimo server is, what version of AJP should use and the port where Geronimo is listening.

Edit the workers.properties file located in the <httpd_home>\conf directory to match your environment. The following example is an excerpt from the workers.properties file with just the variables you should focus on.

worker.ajp13.type=ajp13
# Sets the version of AJP used. The AJP listeners defined in Geronimo are AJP v13.

worker.ajp13.host=localhost
# Specifies the location of the Geronimo server. Use default localhost for single-tier scenarios. Specify the
# hostname of the Geronimo server for multi-tier environments.

worker.ajp13.port=8009
# Both Tomcat and Jetty come with a predefined AJP13 listener on port 8009

From this example note how the name of the worker is defined, look at the variables definition worker.ajp13.* , ajp13 is the worker name you specified earlier in the httpd.conf.

1. Check Geronimo connectivity by accessing http://localhost:8080/console^{Image Removed} , you should see the Geronimo Administration Console.
2. Check HTTPd connectivity by accessing http://localhost^{Image Removed} , you should see the Apache HTTPd welcome page.
3. Check the HTTPd - Geronimo request forwarding by accessing http://localhost/console/^{Image Removed} , you shoud be redirected to the Geronimo Administration Console. Note at the end of the URL there is a "/", failing to include this / will result in a Not Found error triggered by the Jakarta Tomcat Connector module.
