    Exceptions when calling SwitchYard JMX

    Dennis Bohnstedt Hansen Newbie

      Hi

       

       

      I'm trying to use switchyard JMX integration, to do some simple runtime state checking, but im getting some weird errors from my MBean proxies. It looks as if they are not correctly inititalized or something.

       

       

      The code is being run om a JBoss Fuse Service Works 6.0.0.GA.

       

       

      For instance, if I try to list all bindings for a service, using this method, I get a ClassCastException when calling the getState() method on LifecycleMXBean:

       

       

      public List<BindingMXBean> listBindingMXBeansForService(String serviceName) {
        List<BindingMXBean> bindings = new ArrayList<BindingMXBean>();
        try {
        ObjectName objName = new ObjectName("org.switchyard.admin:type=Binding,name=*,service=" + ObjectName.quote(serviceName));
        Set<ObjectInstance> mBeans = ManagementFactory.getPlatformMBeanServer().queryMBeans(objName, null);
        for (ObjectInstance objectInstance : mBeans) {
        BindingMXBean mBean = JMX.newMBeanProxy(server, objectInstance.getObjectName(), BindingMXBean.class);
        bindings.add(mBean);
        // This call fails:
        System.out.println("Binding state: "+mBean.getState());
      
        }
        } catch (javax.management.MalformedObjectNameException badNameEx) {
        throw new IllegalArgumentException(badNameEx);
        }
              return bindings;
        }
      
      

       

      The exception i get:

      I also get the exceptions, when i try to call getApplication() on a Service, and if i try to liste the services of an Application with getServices(), where javax.management.ObjectName is being cast to an ApplicationMXBean. This is the Exception trace from that call:
