Then just follow this example below for your sites available in /etc/apache2, make sure rewrite and proxy are enabled in mods enabled... You can have more tomcat instances in your balancer if you wish.

This came a full day of apache research, but there was one article that helped me make the final leap with the rewrite stuff.
