{{Jetty Feature | introduction =

The Jetty JMX integration is based on the ObjectMBean implementation of DynamicMBean. This implementation allows an arbitrary POJO to be wrapped in an MBean and for meta data to be provided by properties files

The creation of MBeans is coordinated by the MBeanContainer implementation of the Container.Listener interface. The Jetty Server and it's components use a Container to maintain a containment tree of components and to support notification of changes to that tree. The MBeanContainer class listens for Container events and creates and destroys MBeans as required to wrap all Jetty components.

Using Jetty MBeans

The simplest way to use Jetty MBeans is to use the JConsole utility supplied with Sun's Java Virtual Machine. An internal HTTP agent can also be used (see jetty-jmx.xml config file comments).

See Jetty/Howto/Run_Jetty_with_JConsole for instructions on how to configure jmx for use with JConsole.

Jetty Standalone

The MBeanContainer instance can be configured for a Jetty server by the jetty-jmx.xml configuration file. This can be run with the standard configuration file as follows:
java -jar start.jar etc/jetty-jmx.xml etc/jetty.xml
Jetty 7 requires -DOPTIONS=jmx to be used when starting up Jetty. That is, instead of the above, use this: <source lang="text">
java -DOPTIONS=jmx -jar start.jar etc/jetty-jmx.xml etc/jetty.xml
== Jetty Maven Plugin  ==
If you are using the [http://jetty.mortbay.org/maven-plugin/index.html Jetty Maven plugin] you should copy the etc/jetty-jmx.xml file into your webapp project somewhere, such as src/etc, then add a &lt;jettyconfig&gt; element to the plugin &lt;configuration&gt;: <source lang="xml">
