Tomcat lbfactor weight not working

[Jared Parrish]

I'm having some issues with the lbfactor in Tomcat with Apache mod_jk. Everything seems to be working fine except for the load factor. It recognizes the sticky sessions, and it is failing over. Only problem I am having is the fact that it is not recognizing the load factor I have set in workers.properties file. It continues to go back and forth the same, no matter what load factor I have set on each server. I have two servers. I have two Tomcat instances on two different servers. Both of them are running an app on Tomcat with Apache web. Both workers.properties on both servers are identical as well as httpd.conf and server.xml.

Has anybody came across this issue where only the lbfactor was not working? Here are my files. I hate to have such a large post, but I figured you would need to see my config files. Let me know if you need any more info. Any help is appreciated. Thank you.
