I have most recently switched from a Tomcat server with MySQL and PHP to an all in one package that has all of that and more in one simple Windows Installer (they have versions for other OS too). It is called XAMPP. This guide was created to help you get jForum up and running as fast as possible using the XAMPP engine. This guide is strictly for the Windows people but you can get an understanding on what to do if you need to use XAMPP on a different OS also.
Install XAMPP 1.6.6a Basic for Windows(you can use a different version but for this guide, this is the one im using)
