Jetty6 ServiceAgent exposing JMX

In Jetty6 it is possible to configure an SLP ServiceAgent that exposes the MBeanServer where Jetty registers its MBeans.
Follow these steps to configure Jetty6 or Jetty7:

• Create directory $JETTY_HOME/lib/ext/slp. Jetty6 will scan all subdirectories under $JETTY_HOME/lib/ext for additional jars.
• Place livetribe-slp-2.y.z.jar in the $JETTY_HOME/lib/ext/slp directory.
• Create the following Jetty configuration file, that contains the JMX and SLP configuration for Jetty:

  <?xml version="1.0" encoding="UTF-8" ?>
