java.lang.Object | +--mx4j.tools.jython.JythonRunner
This MBean enables you to run scripts written in jython. Scripts can be run using the managed operation runScript or by listening notifcations from another MBean. To us it you need to install jython 2.1 or higher from <a href="http://www.jython.org">here</a> If you want to use a jython library remember to add the jython jar to the classpath in the right location or modify the python.path address The scripts have always the "server" embedded variable which points to the current server. It also automatically import some JMX modules as:
