If you are including mod_jk.conf, then comment out include section and use the following: # C:/.../apache-tomcat/conf/auto/mod_jk.conf # Load mod_jk # LoadModule jk_module modules/mod_jk.s

have a web server such as the Apache HTTP Server forwarding servlet requests to a Tomcat process (the worker) running behind it. The scenario described above is a very simple one; in fact one can configure multiple Tomcat workers to serve servlets on behalf of a certain web server. The reasons for such configuration can be: We want different contexts to be served by different Tomcat workers to provide a development environment where all the developers share the same web server but own a Tomcat worker of their own. We want different virtual hosts served by different Tomcat processes to provide a clear separation between sites belonging to different companies. We want to provide load balancing, meaning run multiple Tomcat workers each on a machine of its own and distribute the requests between them. There are probably more reasons for having multiple workers but I guess that this list is enough... Tomcat workers are defined in a properties file dubbed workers.properties and this tutorial explains how to work with it. Configuration File Basics Defining workers to the Tomcat web server plugin can be done using a properties file (a sample file named workers.properties is available in the conf/ directory). Format, Comments, Whitespace The lines in the file define properties. The general format is
