Jetty Installation

• Download and install Jetty. It's usually as simple as unzipping it in a directory. Let's call this directory [JETTY_HOME].
• Extract the XWiki WAR into a directory named xwiki/ in [JETTY_HOME]/webapps/. The reason you're expanding the WAR is because you'll need to modify one configuration file from inside the WAR later on when you configure the database access.
• (optional) If you want to modify the port on which Jetty will run, edit [JETTY_HOME]/etc/jetty.xml. Search for "8080" and replace with the port value you wish to use.
