How to expose attribute object as JMX

[timfox]

Hi-

I have an object MessagingServer which is instantiate by the MC and declared in our jbm-beans.xml file.

This object has an attribute MessagingServerManagement which is itself an interface that provides the management interface of the messaging server.

That interface contains a set of operations, e.g.

interface MessagingServerManagement
{
 void foo();
 void bar();
}

I want the MC to automatically expose those management operations as JMX operations.

I know how to do this in the case the actual MessagingServerManagement is declared as a top level bean in its own right. (I.e. with @org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.messaging:service=JMSServerManager",exposedInterface=org.jboss.messaging.jms.server.JMSServerManager.class))

But in this case the interface I want to expose is an attribute of a bean, not a top level bean.

Any ideas how to do this?

Create a simple wrapper/delegate around MsgServerMgmnt interface, where all invocations delegate the work to MsgServer::getMsgServerMgmnt attribute.
And then simply do @JMX as you already know.

Yeah, I thought of this, but it seems pretty ugly. Would be nice if MC could do this automatically - an ability to use the JMX annotation on an attribute too.

Sounds reasonable to me.
