[jboss-user] [Beginners Corner] - Starting/Stopping MDB via JMX

[pbaker01]

First I know that the questions below has been asked many times.  I have seen several posts where the replies say: "Search for the Answer".  I have searched and I can't find it... 

Problem:
I have a queue and a listener.  The listener is configured as an MDB.  I want to be able to:

o Start/Stop the Queue via JMX
o Start/Stop the Queue progrmatically


I cannot find an answer for either.  First the JMX issue

Environment:
JBoss: Jboss-5.0.0 GA
JDK:    jdk1.6.0_10

Below is the code for my MDB:
import javax.ejb.ActivationConfigProperty;
  | import javax.ejb.MessageDriven;
  | import javax.jms.JMSException;
  | import javax.jms.Message;
  | import javax.jms.MessageListener;
  | import javax.jms.TextMessage;
  | 
  | @MessageDriven(mappedName = "jms/SSMListener", activationConfig = {
  | 		@ActivationConfigProperty(propertyName="messagingType", propertyValue="javax.jms.MessageListener"),
  | 		@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
  | 		@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
  | 		@ActivationConfigProperty(propertyName="destination",propertyValue="queue/SSMQueue") })
  | public class SSMListener implements MessageListener {
  | 
  | 	public void onMessage(Message arg0) {
  | 		// TODO Auto-generated method stub
  | 		TextMessage tm = (TextMessage) arg0;
  | 		try {
  | 			System.out.println("I'm alive - " + tm.getText());
  | 		} catch (JMSException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}
  | 	}
  | }

JBoss.xml:
<jboss>
  |  <enterprise-beans>
  |  <message-driven>
  |  <ejb-name>SSMListener</ejb-name>
  |  <local-jndi-name>jms/SSMListener</local-jndi-name>
  |  <destination-jndi-name>queue/SSMQueue</destination-jndi-name>
  |  </message-driven>
  |  </enterprise-beans>
  | </jboss>
  | 

destinations-service.xml
  <mbean code="org.jboss.mq.server.jmx.Queue"
  | 	 name="jboss.mq.destination:service=Queue,name=SSMQueue">
  |     <depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
  |   </mbean>
  | 

Here is are two snapshots of my JMX console.

I don't see any JMX controls for startDelivery or stopDelivery. 
o What am I doing wrong here? 
o Do I need to configure the MDB as an mbean?  

Remember - beginner... 

For start/stoping programatically I have the following code:
		ObjectName objectName;
  | 		try {
  | 			objectName = new ObjectName(
  | 					"jboss.j2ee:binding=message-driven-bean, jndiName=jms/SSMListener, plugin=invoker,service=EJB");
  | 			MBeanServer server = MBeanServerLocator.locateJBoss();
  | 			server.invoke(objectName, "stopDelivery", new Object[] {}, null);
  | 		} catch (MalformedObjectNameException e1) {
  | 			// TODO Auto-generated catch block
  | 			e1.printStackTrace();
  | 		} catch (NullPointerException e1) {
  | 			// TODO Auto-generated catch block
  | 			e1.printStackTrace();
  | 		} catch (InstanceNotFoundException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		} catch (MBeanException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		} catch (ReflectionException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}

This code generates exception:
anonymous wrote : 10:55:55,157 ERROR [STDERR] javax.management.InstanceNotFoundException: jboss.j2ee:binding=message-driven-bean, jndiName=jms/SSMListener, plugin=invoker,service=EJB is not registered.
  | 10:55:55,158 ERROR [STDERR] 	at org.jboss.mx.server.registry.BasicMBeanRegistry.get(BasicMBeanRegistry.java:529)
  | 10:55:55,158 ERROR [STDERR] 	at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:662)
  | 10:55:55,158 ERROR [STDERR] 	at com.sita.wab.service.SsimService.startLoad(SsimService.java:65)
  | 10:55:55,158 ERROR [STDERR] 	at com.sita.wab.ejb.ssim.SsimEjbBean.startLoad(SsimEjbBean.java:32)

I suspect once I get the JMX issue resolved the answer to this problem will be obvious. 

Other than the starting/stopping the queue, everything else works well.

Please be cognizant that I have posted this on the "Beginners Corner" forum and I am not that familure with the details of JMX.

Any help will be greatly appreciated.
