    Can't expose 'start' for a service XMBean

    Mike Osganian Newbie

      I can't figure out how to expose a start service using an XMBean. I started with the code in the JBoss EJB3 tutorial (XMBeanService.java) and modified it to include:

      public void start() {
       System.out.println("Start was called");
      }
      

      Deploying the JAR produced the expected output. I then added the following to the service-xmbean.xml file:
      <operation>
       <name>start</name>
       <return-type>void</return-type>
      </operation>
      


      This produced the following exception:

      Adding a start method to XMBeanServiceRemote.java and deploying the service bean with the Management annotation
      @Management(XMBeanServiceRemote.class)
      
      worked just fine. Am I missing something, or is there perhaps a bug?
