[<dim...@jb...>]

Where is this code taken from? Can you provide more context?

Please check the doStart() of the ServerImpl , here it goes

I'm not following your question then. The MBeanProxyExt is simply used to obtain a typesafe proxy on the jmx bean whose management interface is MainDeployerMBean. The standard jmx equivalent is to use the javax.management.MBeanServerInvocationHandler:


  |       ObjectName mainDeployer = ...;
  |       MBeanServer server = ...;
  |       MainDeployerMBean proxy = (MainDeployerMBean) MBeanServerInvocationHandler.newProxyInstance(
  |          server, mainDeployer, MainDeployerMBean.class, false);
  |

Scott,
Why can't we have 

  | Object[] args = //URL
  | String[] sig =    //void 
  | server.invoke(mainDeloyer,"deploy",args,sig);
  | 
instead of this 

  | MainDeployerMBean md = (MainDeployerMBean)
  |          MBeanProxyExt.create(MainDeployerMBean.class, mainDeployer, server);
  |       try
  |       {
  |          md.deploy(config.getServerConfigURL() + config.getRootDeploymentFilename());
  |       }
  |       catch (IncompleteDeploymentException e) {
  |          log.error("Root deployment has missing dependencies; continuing", e);
  |       }
  | 
This is what I am trying to say , as the code becomes more understandable .

Regards
Vicky

The reason for using the typed proxy is that we believe that code is more readable/understandable when the proxy is used. Otherwise you are using a reflective type call every time an invocation is done, as opposed to a typed proxy.

Yes, got it now!!!!
I think my understanding about the usage of the MBeanProxyExt was wrong, I initilly though that this was used for optimization as I could see the invocation to getter/setter handled by simply invoking the corresponding attributes.
Yes now I realize that this make code more readable/understandable than simply keeping the reflective calls in the code.
