(Author's original, you can reprint, please indicate the source) http://blog.9cbs.net/zmxj This simple MBean only has a property and a method, startbeandemomain calls the following three methods in the MAIN method, the code There are detailed notes: sbean.doMladbean (); sbean.domanagebean (); sbean.Reghtmladaptor (); After running, you can see the information printed by the console, Register Standmbean Sucess..attribute: State -init ValueAttribute: State 2 -new StateMy Service Start ..... Due to the start of HTMLADAPTOR, the program has been running, (HTMLADAPTOR is a Adapter that comes with the SUN JMX) Test can be accessed in the browser: http: // localhost: 8082 You can manage MBean in your browser. Press STARVICE button under List of MBean Operations to see the information you play in the console, indicating that the StartService method is called. JDK1.4 requires jmxri.jar and jmxtools.jar two packages, and JDK50 already includes JMX's API.
