How to get PerformanceProfiler/DMS/JMX for TopLink working on GlassFish

Question

Greetings, all
I'm trying to configure Toplink 11.1.1.0 (instead of Toplink Essentials) as JPA provider to run on GlassFish V1 UR1 with performance monitoring via PerformanceProfiler and cache invalidation when needed, with the following configuration
persistence.xml
- <provider>oracle.toplink.ejb.cmp3.EntityManagerFactoryProvider</provider>
code extract 1
em = (EntityManager)emf.createEntityManager();
session = em.getServerSession();
PerformanceProfiler pp = new PerformanceProfiler(session);
session.setProfiler(pp);
code extract 2
session.getIdentityMapAccessor().invalidateClass(clazz);
(A) However, I got the following exception and would appreciate any advice of any correction(s) needed and how to get it working.
Internal Exception: Exception [TOPLINK-28007] (Oracle TopLink - 11g Release 1 (11.1.1.0.0) (Build 070502)): oracle.toplink.exceptions.EntityManagerSetupException
Exception Description: Failed to instantiate ServerPlatform of type [oracle.toplink.essentials.platform.server.sunas.SunAS9ServerPlatform] specified in [toplink.target-server] property.
Internal Exception: java.lang.NoSuchMethodException: oracle.toplink.essentials.platform.server.sunas.SunAS9ServerPlatform.<init>(oracle.toplink.sessions.DatabaseSession)].
com.sun.enterprise.admin.event.AdminEventListenerException: javax.persistence.PersistenceException: Exception [TOPLINK-28018] (Oracle TopLink - 11g Release 1 (11.1.1.0.0) (Build 070502)): oracle.toplink.exceptions.EntityManagerSetupException
Exception Description: (There is no English translation for this exception.)
(B) Btw, it seems :
a. oracle.toplink.platform.server.sunas.SunAS9ServerPlatform does not exist in toplink.jar
b. oracle.toplink.essentials.platform.server.sunas.SunAS9ServerPlatform exists in toplink-essentials.jar but not in toplink.jar
So my questions are :
a. Only TopLink Essential (but not TopLink 11.1.1.0 JPA) currently support GlassFish ?
b. But TopLink Essential does not not support for PerformanceProfiler/DMS monitoring?
c. Hence, there is no way to get PerformanceProfiler/DMS/JMX monitoring for JPA for TopLink on GlassFish. If that's the case, when will PerformanceProfiler/DMS/JMX monitoring be supported with GlassFish?
d. Is TopLink 11.1.1.0 JPA compliant? If yes, we should be able to get it working on GlassFish. Is there a sample application to show how this is actually done?
Welcome and appreciate much any correction / advice if I've missed anything how to get PerformanceProfiler/DMS/JMX monitoring on TopLink (also TopLink cache) working on GlassFish / pointers to information in case it was documented, or discussed before.
Btw, it seems that I was able to get session cache (per class/object/all) invalidation working using TopLink Essentials with GlassFish, but again, no performance monitoring (e.g. using JMX) there (as also mentioned on http://www.oracle.com/technology/products/ias/toplink/jpa/resources/faq.html#13)
Thanks a lot !!
Best regards.

Hello David,
The problem seems to be with,
MBeanServer mbeanServer = MBeanServerFactory.createMBeanServer();
This does not get the MBeanServer that weblogic server uses. Try getting
the MBeanServer from MBeanHome and register your MBean in this server.
Check out
http://e-docs.bea.com/wls/docs81/jmx/basics.html
to lookup MBeanHome and getting the MBeanServer.
Thanks,

Like other people reading this group, I'm trying to get started with JMX in WebLogic (8.1) despite the apparent lack of useful information.
I'll eventually be writing an mbean which is intended to run on each managed server (registered by a servlet) which will read and write a particular file on each managed server (contention problems are unavoidable).
In the beginning, however, I'm just trying to build a simple POC, with a servlet that creates and registers a simple mbean. That part was deceptively easy, but I'm not sure I did it right, as I'm not sure of the best way to look at the results of what I did.
I found the "wlshell" tool, which is a jmx client for WebLogic. After my servlet registers the mbean, I tried reloading the wlshell display, but I don't see anything new. I'm sure I'm misunderstanding something (probably in the "ObjectName" constructor).
The "init()" method of my servlet looks like this:
public void init()
MBeanServer mbeanServer = MBeanServerFactory.createMBeanServer();
Sample sample = new Sample();
try
ObjectName objectName = new ObjectName("Sample:name=sample");
mbeanServer.registerMBean(sample, objectName);
The Mbean and impl look like:
public interface SampleMBean
public void setFlag(boolean flag);
public boolean getFlag();
public class Sample implements SampleMBean
private boolean flag;
public void setFlag(boolean flag) { this.flag = flag; }
public boolean getFlag() { return (flag); }
