Project overview

This enhancement will add JMX MBean support to EclipseLink 1.0 by exposing runtime and

Goals:

Concepts

Based on JMX 1.2 and JMX Remote API 1.0

References

ELUG Documentation JMX MBeans in WebLogic 10

Requirements

Phase 1: WebLogic 10 MBean support

  • R1: Enable JMX MBean Support for WebLogic
    • R1.1: Enable predeploy MBean registration
    • R1.2: Enable application managed lazy-load MBean registration (post-deploy)

Phase 2: Generic MBean support

    • R2: Enable JMX MBean support for generic J2EE servers


Design Constraints

Use Cases

Design / Functionality

Predeploy Registration

Lazy Registration

Here the application can manage registration/deregistration of the MBeans by using a SessionCustomizer in conjunction with a listener on either a servlet or session bean within the JEE application.

  • SessionCustomizer
  • Listener

You must configure the EclipseLink Mbeans in the EAR/meta-inf via a weblogic-application.xml descriptor entry.

<!DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN"  "http://java.sun.com/dtd/application_1_3.dtd">
<weblogic-application xmlns="http://www.bea.com/ns/weblogic/10">
    <listener>
       <listener-class>org.eclipse.persistence.example.unified.integration.ApplicationLifecycleListenerImpl</listener-class>
    </listener>
</weblogic-application>


Testing

A formal JMX J2SE client test suite is required.
