I found the following thread, but no response as yet:

We are busy with a jbas4.2.2 -> 5.1.0.GA migration, and have an mbean:
MyMBeanService.java:
| @Service(objectName = "mycompany:service=MyMBeanService")
| @Management(MyMBeanServiceMBean.class)
| public class MyMBeanService extends ServiceMBeanSupport implements
MyMBeanServiceMBean {}
|
MyMBeanServiceMBean.java:
| public interface MyMBeanServiceMBean {}
|
It is being mapped as an mbean, via jboss-service.xml:
| <mbean code="com.mycompany.mypackage.management.MyMBeanService"
| name="mycompany:service=MyMBeanService">
| </mbean>
|
When I deploy this to JBAS 5, I get the following error:
| ERROR [org.jboss.management.j2ee.MBean] (main) Could not destroy JSR-77
MBean: mycompany:service=MyMBeanService
| javax.management.MBeanRegistrationException: preDeregister
| at org.jboss.mx.server.registry.BasicMBeanRegistry.unregisterMBean
| ....
| Caused by: javax.management.RunimeOperationsException
| at org.jboss.mx.server.MBeanServerImpl.removeNotficationLister
| ...
| Caused by: java.lang.IllegalArgumentException: The MBean
mycompany:service=MyMBeanService exists but does not implement the
NotifcationBroadcaster interface.
|
So I added the implementation:
| public class MyMBeanService extends ServiceMBeanSupport implements
MyMBeanServiceMBean, NotificationBroadcaster {}
|
which results in the following error
| ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController]

| org.jboss.deployers.spi.DeploymentException: Error deploying Project.sar:

I found a reference to the EJB 3 spec on JBoss Jira:
"if a bean class implements a single interface, that interface will be assumed
to be the business interface of the bean."
And if a bean class implements more than 1 interface, then the business
interface is specified through @Local or @Remote.
So I added the annotation to MyMBeanServiceMBean:
| @Local
| public interface MyMBeanServiceMBean {}
|
After deploying this, I get the same error about the mbean existing, but not
implementing NotificationBroadcaster interface (even though the bean does
implement NotificationBroadcaster).
I have also tried extending NotificationBroadcaster in the ServiceMBean:
| public interface MyMBeanServiceMBean extends NotificationBroadcaster {}
|
which also still results in the not implementing notificationbroadcaster error.
Not sure how to resolve this for this implementation (or perhaps a bug?)
