extending class that extends ServiceMBeanSupport

[jimdwyer]

Folks,

Here is what I would like to do:

public interface TestMBean extends org.jboss.system.ServiceMBean{}

public abstract class AbstractTestService
extends org.jboss.system.ServiceMBeanSupport
implements TestMBean{

public abstract boolean testMethod();
}

public class TestService extends AbstractTestService{

public boolean testMethod(){}
}

This arrangment will not run. It throws a NotCompliantMBeanException. Class does not expose a management interface: java.lang.Object

Any ideas as to why?

You need to read the jmx spec to understand the standard mbean inheritence rules.

One solution is to make TestService implement a TestServiceMBean interface.

Thanks Guys,

I got it working. It was mostly a deployment issue.

On second thought....

Dimitris - you are correct. By having TestService implement a TestServiceMBean interface the whole things falls into place very nicely.

Thanks again.

Jim
