Перенос MBean с JBoss 4.x на JBoss 7

Singleton EJB с @Startup? http://www.adam-bien.com/roller/abien/entry/singleton_the_simplest_possible_jmx

Я думаю, что более лаконичный способ сделать это - использовать расширение CDI. Взгляните на решение, которое мы используем:

@Documented
@Retention(value=RUNTIME)
@Target(value=TYPE)
@Inherited
public @interface MBean {
    String value() default "";
}

...

Это рабочий код расширения CDI:

public class ManagementExtension implements Extension {

    private static Logger log = LoggerFactory
            .getLogger(ManagementExtension.class);

    public <T> void processInjectionTarget(@Observes ProcessInjectionTarget<T> pit) {

        // check if the MBean annotation is present
        AnnotatedType<T> at = pit.getAnnotatedType();
        if (at.isAnnotationPresent(MBean.class)) {
            // it makes sense to register JMX interfaces only for singletons
            if (!at.isAnnotationPresent(Singleton.class)) {
                log.warn("Ignoring attemt to register JMX interface for a non-singleton EJB: "
                        + at.getJavaClass().getName());
                return;
            }

            try {
                // decorate the InjectionTarget
                InjectionTarget<T> delegate = pit.getInjectionTarget();
                InjectionTarget<T> wrapper = new JmxInjectionTarget<T>(delegate, getObjectName(at));

                // change the InjectionTarget with the decorated one
                pit.setInjectionTarget(wrapper);
            } catch (Exception e) {
                log.warn("Cannot get JMX object name for: " + at.getJavaClass().getName(), e);
            }

        }
    }

    private <T> ObjectName getObjectName(AnnotatedType<T> at) throws MalformedObjectNameException {

        String name = at.getAnnotation(MBean.class).value();

        if (name.isEmpty()) {
            name = at.getJavaClass().getPackage().getName() + ":type="
                    + at.getJavaClass().getSimpleName();
        }

        return new ObjectName(name);
    }

    private class JmxInjectionTarget<T> implements InjectionTarget<T> {

        private final InjectionTarget<T> d;
        private final ObjectName objectName;

        public JmxInjectionTarget(InjectionTarget<T> delegate, ObjectName objectName) {
            this.d = delegate;
            this.objectName = objectName;
        }
        @Override
        public void dispose(T instance) {
            d.dispose(instance);
        }

        @Override
        public Set<InjectionPoint> getInjectionPoints() {
            return d.getInjectionPoints();
        }

        @Override
        public T produce(CreationalContext<T> ctx) {
            return d.produce(ctx);
        }

        @Override
        public void inject(T instance, CreationalContext<T> ctx) {
            d.inject(instance, ctx);
            //the next piece of code better be done in postConstruct but...
            //got no idea why but postConstruct never gets called
            //for Singleton EJB bean
            MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
            try {
                if(mBeanServer.isRegistered(objectName))
                mBeanServer.unregisterMBean(objectName);
                mBeanServer.registerMBean(instance, objectName);
            } catch (Exception e) {
                log.warn("Cannot register "+objectName, e);
                return;
            }
            log.info("added JMX registration for: " + objectName);
        }

        @Override
        public void postConstruct(T instance) {
            d.postConstruct(instance);
        }

        @Override
        public void preDestroy(T instance) {
            d.preDestroy(instance);
        }

    }
}

Затем просто отметьте свой класс аннотацией @Mbean, и он будет автоматически зарегистрирован на сервере Mbean:

@Startup 
@Singleton 
@MBean("com.company=JmxBindName")
public class SomeService

Работает как шарм)
