JAMP: an ultra portable PHP, web server and database stack in Java – This tutorial describes how to set up the PHP and database stack in the Jetty web server. First we set up a web application (webapp for short) in Java which can interpret .php files using Quercus. Then we setup the H2 database engine. Last, we setup the part where PHP can connect to H2 while actually thinking it is MySQL that it's connecting to (using H2's MySQL compatibility mode, because PHP does not have support for H2). Here we go!
