I've updated the Jamp! All packages are updated to the latests stable version available, the "Server" and "Service" commands are added for Tomcat 6.0, Jamp.hta UI is updated

Jamp! is a single-click installer for PHP/Java/Apache/MySQL to make installing them (and getting them working together) simple.
