Explanation/Reference:
The Java EE Management specification (JSR 77) provides a standard model for managing a J2EE Platform and describes a standard data model for monitoring and managing the runtime state of any Java EE Web application server and its resources.
Note: The J2EE Management specification includes standard mappings of the model to the Common Information Model (CIM), to an SNMP Management Information Base (MIB), and to the Java object model through a server-resident Enterprise JavaBeans (EJB) component, known as the J2EE Management EJB Component (MEJB). The MEJB provides interoperable remote access to the model from any standard J2EE application.
