JellyMBean is a Jelly library for creating, configuring and registering beans and MBeans with a JMX server. JellyMBean uses the JellyBean library to create and configure beans and extends it to support JMX operations.

JellyMBean is similar to the MLET parser in mx4j and JBoss and the Ant tasks in commons-modeler

There is an example JellyBean deployment descriptor file here.
