Hi,

Jay SenSharma

An application represents a J2EE Enterprise application packaged in an EAR file or EAR exploded directory. The EAR file or directory contains a set of components such as WAR, EJB, and RAR connector components, each of which can be deployed on one or more targets. A target is a server or a cluster.

ApplicationRuntimeMBean encapsulates runtime information about a deployed Enterprise application.

Here is a Sample JMX code to display the State of all the Applications deployed on All the Servers…
