JMX API Enhancements

Enhancements in Java SE 7

There were no API changes to JMX in Java SE 7.

Generification.
The JMX API now fully supports Generics.
ObjectName supports wildcards.
key=* wildcards are now supported in ObjectName. Previously, "domain:key1=value1,*" could be used to match MBeans that have key1=value1 in their name, but "domain:key1=*" could not be used to match MBeans that have key1 in their name. This is now possible.
New JMX class.
A new class, javax.management.JMX, has been added to house constants and static methods.
MBean Descriptors added.
MBean Descriptors have been added. Descriptors allow you to give additional information about MBeans to management clients. See MBean Descriptors in the JMX Technology Tutorial for information.
MXBeans added.
MXBeans have been added. MXBeans are MBeans that provide a convenient way to bundle related values together without requiring clients to be specially configured to handle the bundles. A defined set of MXBeans already existed in the J2SE 5.0 platform, but Java SE 6 introduces an API to allow you to program your own custom MXBeans. See Introducing MXBeans in the JMX Technology Tutorial for information.

JMX Monitor API now supports complex types.
Improvements have been made to the JMX Monitor API to support complex types. Previously, only attributes of simple types could be monitored, but often, the value to be monitored is buried inside a more complex type. See the JMX Specification, version 1.4, for details of the behavior of monitors.

For the full list of JMX API enhancements added in the Java SE platform, version 6, see the Java SE 6 JMX API enhancements.

The Java Management Extensions (JMX) technology became a part of the Java platform in the Java 2 Platform, Standard Edition (J2SE) 5.0.
