[jboss-user] [Management, JMX/JBoss] - Problem registering @Management interface for @Service class

[Renen]

Hello,

I would very much appreciate some assistance.

I am trying to create a"service" - effectively a singleton that is loaded on start-up. 

This worked in JBoss 4x. I am now trying to port the code to jboss-5.0.0.CR2...

My code is as follows:


  | public interface ProcessManager {
  | 
  | 	public void create() throws Exception;
  | 	public int getID();
  |     
  | 
  | }
  | 

And:


  | @Service (objectName="121:service=processManager")
  | @Management(ProcessManager.class)
  | @TransactionAttribute( TransactionAttributeType.NOT_SUPPORTED )
  | public class ProcessManagerMBean implements ProcessManager {
  | 	
  | 	@Override
  | 	public void create() throws Exception {
  | 		System.out.println("Process create");	
  | 	}
  | 
  | 	@Override
  | 	public int getID() {
  | 		return 2;
  | 	}
  | 	
  | 	
  | }
  | 


However, when this is deployed, JBoss complains:


  | Problem registering @Management interface for @Service class

What am I doing wrong?

Also, why does it demand an "EJBTimerService"?

Thank you very much for your time.

Renen.
