III. Basic Concepts1: mbeanIt is usually a Java class that provides interfaces to make this class have management functions (such as standard mbean, methods defined in the interface make mbean have management functions ).2: mbean ServerMbean is a Java class for mbean management. You need to register an mbean with mbean server before mbean can be managed. mbean server also provides the query function and listener registration function, sun only provides interfaces, and mbean Server impl

If you've checked the class in the example, you can now run the example. In this example, the jconsole is used to interact with the Mbean. Save the JMX example of the compressed package Jmx_examples.zip to your working directory Work_dir. At the command line or terminal, use the following command to extract the package: Unzip Jmx_examples.zip. Compile the example in the Work_dir directory for all classes: Javac Com/example/*.java. If y
start with a simple review of the JMX API, Spring Framework, and spring JMX, and then move on to the development extension. The first extension allows me to configure MBean metadata in an external XML format, which, like Hibernate mapping files, can be stored with Java objects in the classpath. My second extension adds a simple naming convention for the Modelmbean class to transparently configure custom no

JMX is becoming increasingly popular in various technical journals, white papers, and reports, although it is no longer a buzzword. Not just sun ?, Many vendors have recently announced that they are or are preparing to support this technology. Not only are large vendors such as IBM, Bea, HP, and marcomedia (JRun), but also many small software companies and open-source projects, incl
