In this "switching port" issue; you should use mod_proxy and/or
mod_rewrite to tell apache when a user is requesting tomcat and when
standard webpages. This is beyond a mapserver topic and should be
addressed to communities involved with Apache.

You'd normally never use Tomcat to serve files in the way you'd use Apache httpd. You'd normally delegate such a task to a webserver. And there really isn't much of an issue about having the two servers installed, we sorted out the port conflict issues a while back.

You can also access these via PHP, Python and others even Java it seems, using mapscript. But being able to script in Java is still a long way from being able to deploy to a servlet container like Tomcat.
