JMX is the Java Management Extensions. This extension provides tools for managing and monitoring devices, applications, and service-driven networks. JE supports this extension.
The JE distribution supplies an MBean that can be deployed for monitoring a JE environment in any JMX server (such as an J2EE application server). Alternatively, applications can use JE helper classes to add JE monitoring to their own JMX MBean implementations.
For information on how to deploy the standalone JE JMX MBean, or on how to use JE helper classes to build an application-specific MBean, see:
