I use Apache’s Forrest tool, which uses internally the Jetty engine. I wanted to make Jetty listen to instead of, so my computer wouldn’t show up in a enterprise port scan.

I had trouble finding the information. I went looking for the link again without any success. So I am posting it here, where I will always be able to find it !

Update 2008-01-25 : You must add this XML to the file $FORREST_HOME/main/webapp/jettyconf.xml

<Call name="addListener">
    <New class="org.mortbay.http.SocketListener">      <!-- Add this next line -->
      <Set name="Host"><SystemProperty name="jetty.host" default="localhost"/></Set>
      <Set name="Port"><SystemProperty name="jetty.port" default="8888"/></Set>
      <Set name="MinThreads">5</Set>
      <Set name="MaxThreads">100</Set>
      <Set name="MaxIdleTimeMs">30000</Set>
      <Set name="LowResourcePersistTimeMs">5000</Set>

You know its working when you see this in the Forrest window:

21:05:11.864 EVENT  Apache Cocoon 2.2.0-dev is up and ready.
21:05:11.864 EVENT  Started SocketListener on
