Hi, i have declared a mbean like that example: MyServiceMBean.java @Service(objectName="MyApplication:service=MyService") | @Management(MyManagementInterface.class) | public class MyServiceMBean implements MyManagementInterface { | | public void printOut(String text) { | System.out.println("Given text: " + text); | } | | } MyManagementInterface.java: public interface MyManagementInterface { | public void printOut(String text); | } Works so far fine. BUT if I write following in "MyServiceMBean.java": public class MyServiceMBean implements MyManagementInterface, org.quartz.TriggerListener { | ... | } I get a deployment exception: org.jboss.deployers.spi.DeploymentException: Error deploying xyz.jar: Error creating ejb container MyServiceMBean: Bean Class xyz.MyServiceMBean has no local, webservice, or remote interfaces defined and does not implement at least one business interface: MyServiceMBean I was a little bit confused about this message. Extending MyManagementInterface from org.quartz.TriggerListener works fine but trashes the management interface in the jmx-console. Adding @Local(MyManagementInterface.class) to the MBean the deployment works fine and keeps the management interface clean. But is the annotation really neccessary? Is this behaviour intended?
