Whilst reading the news concerning the previously commercial JMX implementation “XMOJO being open sourced”:http://www.theserverside.com/home/thread.jsp?thread_id=20791 over at “The Serverside”:http://www.theserverside.com/, I found (due to the post’s helpful comments) that its far from being the only one:

* “MX4J”:http://mx4j.sf.net is currently being used in “Tomcat”:http://jakarta.apache.org/tomcat. MX4J supports the JMX 1.1 specification, and the team are working on the 1.2 specification (XMOJO only supports 1.0)
* “MC4J”:http://mc4j.sourceforge.net/ has some nice management features
* And finally, whilst not an implementation of the JMX API, the “Jakarta commons-modeler”:http://jakarta.apache.org/commons/modeler.html project simplifies the often complex creation process for MBeans.
