Jetty6 now has support for XBean. This allows you to use a neat compact XML format to customize Jetty within an XBean configuration file along with configuring other Geronimo projects like ActiveMQ or ServiceMix.

e.g. the following shows how to configure Jetty inside an XBean configuration file.

  <jetty xmlns="">
      <nioConnector port="8181" />

      <webAppContext contextPath="/" resourceBase="/tmp/webapp" parentLoaderPriority="false" />


There is also an auto-generated XSD and HTML reference for the XML configuration language
