[jboss-user] [Installation, Configuration & Deployment] - MBean service either has no business interface or does not i

[brettcave]

I found the following thread, but no response as yet:
http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4180208

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] (HDScanner) Error installing to Real: name=vfszip:/usr/share/jbo
  | ss/jboss-5.1.0.GA/server/all/farm/7-Project-ear.ear/ state=PreReal mode=Manual requiredState=Real
  | org.jboss.deployers.spi.DeploymentException: Error deploying Project.sar: Error creating ejb container MyMBeanService: Bean Class com.mycompany.project
  | .management.MyMBeanService has no local, webservice, or remote interfaces defined and does not implement at least one business interface: MyMBeanService
  |         at org.jboss.ejb3.deployers.Ejb3Deployer.deploy(Ejb3Deployer.java:196)
  |         at org.jboss.ejb3.deployers.Ejb3Deployer.deploy(Ejb3Deployer.java:99)
  | 

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?)
