Projector is a J2EE application and as such needs a J2EE 1.3-compliant application server or at least a servlet container. If you download Projector as part of the Slide/Tomcat bundle you’ll have a ready-to-run installation that will work fine for smaller projects. This installation is suited for small projects as it is sharing the same servlet container as the Slide server. If you want to serve a web application with high traffic you can install the Projector/Geronimo bundle that is preconfigured to run in a distributed environment.
