I am trying to integrate Tomcat6 and Apache webserver2.2.19 and the Jdk being java6.

I have added the following in the httpd.conf

LoadModule jk_module "G:/ApachWebServer/Apache Software Foundation/Apache2.2/modules/"

ProxyPass /neoapp/examples/ ajp://localhost:8009/examples/

JkWorkersFile "G:/tomcat6.0.32/Apache Software Foundation/Tomcat 6.0/conf/"

JkLogFile "G:/tomcat6.0.32/Apache Software Foundation/Tomcat 6.0/conf/from_apache_mod_jk.log"

JkLogLevel info

JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

#send servlet for context /examples to worker named ajp13

JkMount /examples ajp13

#send jsps for context /examples/* to worker named ajp13

JkMount /examples/* ajp13

The server.xml of the tomcat is as follows
<?xml version='1.0' encoding='utf-8'?>

I have copied the and renamed to and kept it at the modules folder of the apache2.2 home diretory

I ran the tomcat server . Then I tried to run the apache2.2 server from the apache service monitor but it prompts "the requested operation has failed ".

What to do ???

If you're using Tomcat6 and Apache 2.2 then there's really no need to use mod_jk. I know a lot of the literature out there is configuration for mod_jk and you CAN use it in this case, but you're creating a lot of extra work for yourself.

Here's a blog post that includes details on how to use mod_proxy which is the most current method, and is already installed in your Apache. It's focused on using this stuff with Liferay, but the connecting Apache to Tomcat stuff is universal.
