The Basic Components

There are a few important components you need to set this up as a framework

1. An MBeanConnection

2. A type-safe proxy generator

3. An applicable JMX service URL, Port, Hostname

To export mbeans to the client

1. ObjectName that can be connected to if they are services

2. Ports for those services where applicable (i.e. a broker)

3. Interfaces to proxy

I. The Goal: export mbean data by remoting to the client

I created a service which is mirrored as a Flex actionscript class for remoting which encapsulates the calls for various system monitoring data via jmx: This I registered for remoting in the framework of choice, in my case it was Flex. I have a custom annotation that handles this which I don’t include in this snippet.

public class ClientMBeanService implements IClientMBeanService { ..view the code… }

II. The Delegate

With the idea of each component to be exported create a Delegate class that implements the interface dictating the contract that it must implement a method to provide the port, the ObjectName and export the mbean:

public class BrokerDelegate implements IMBeanDelegate { ..view the code… }

All Delegates must implement

public interface IMBeanDelegate { ..view the code… }

III. For Remote and Local MBeanConnections

public class MBeanConnection { ..view the code… }

IV. The Cool Part: Get a Typesafe Proxy Intance of The MBean

public final class MBeanProxyInstance { ..view the code… }

V. Typesafing: I did not originally write this class, only modified it for Java 6, but the crux is:

public class TypeSafeMBeanProxy { ..view the code… }
