Note: these instructions assume that you have JRE 1.5 or better installed on your computer (most Mac and Linux distributions already have one.) If you don't have one, you can get one from http://java.sun.com/javase/downloads/.

Installing the Jetty Servlet Container

The official site for Jetty is http://jetty.mortbay.org/. You can download the latest distribution at http://dist.codehaus.org/jetty/. At the time of writing, the latest version was 6.1.18, but you're probably safe just downloading the latest release (not prerelease) version. The download will be a ZIP file, which you should unzip wherever you want to run Jetty - there is no installation procedure. Now, go to the directory where you unzipped Jetty and type "java -jar start.jar". You should see something like this:
$ java -jar start.jar

Visit http://localhost:8080 in your web browser and you should see a welcome page confirming that you successfully installed Jetty. Go back to your prompt and hit Ctrl- C to stop it.

Installing the Sesame Web Application

There should be a directory within the archive called war. This directory contains two files, openrdf-sesame.war and openrdf-workbench.war, which are web archives for your Java server. Simply copy these files into the webapps directory of your Jetty installation. When you restart Jetty, you should see a message telling you that these two war files were detected and installed as new applications.

Now visit http: //localhost:8080/openrdf-workbench with your web browser and you should see the Sesame Workbench pages.
