I am using the jms/atmosphere framework to make communication between two
applications.
One of the applications is a message producer for a topic, sending custom
objects of the following type:

        @XmlRootElement
        public class A implements Serializable{
        public A(){}

        /* some private properties */

       }

On the other side more than one consumers are listening on the topic and
make different subscriptions depending on the id.

        @GET
        @Produces({MediaType.APPLICATION_JSON})
        public SuspendResponse subscribe() {
        return new SuspendResponse.SuspendResponseBuilder ()
                .broadcaster(topic)
                .outputComments(true)
                .addListener(new EventsLogger()).build();
        }
       @Override
    public void incomingBroadcast() {
        try {
            String id = getID();
            if (id.startsWith("/*")) {
                id = "atmosphere";
            }

            logger.info("Looking up Connection Factory {}", FACTORY_NAME);
            Context ctx = new InitialContext();
            ConnectionFactory connectionFactory = (ConnectionFactory)
ctx.lookup(FACTORY_NAME);

            logger.info("Looking up topic: {}", TOPIC_NAME);
            Topic topic = (Topic) ctx.lookup(TOPIC_NAME);

            connection = connectionFactory.createConnection();
            session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);

            logger.info("Create consumer for : {}", id);
            String selector = String.format("BroadcasterId = '%s'", id);

            consumer = session.createConsumer(topic, selector);
            consumer.setMessageListener(new MessageListener() {

                @Override
                public void onMessage(Message msg) {
                    try {
                        ObjectMessage om = (ObjectMessage) msg;
                        A a = (A) om.getObject();
                        if (a!= null && bc != null) {
                            broadcastReceivedMessage(a);
                        }
                        logger.info("Broadcasted message: {} ", a);
                    } catch (JMSException ex) {
                        logger.warn("Failed to broadcast message", ex);
                    }
                }
            });
            publisher = session.createProducer(topic);
            connection.start();
            logger.info("JMS created for topic {}, with filter {}",
TOPIC_NAME, selector);
        } catch (Throwable ex) {
            throw new IllegalStateException("Unable to initialize
MyBroadcaster", ex);
        }

    }
What I notice is that the messages are arriving correctly on the JMS topic,
but I receive the following exception:

       SEVERE: A message body writer for Java class A, and Java type class
A, and MIME
       media type text/html was not found
       
       SEVERE: The registered message body writers compatible with the MIME
media type are:

I am using Netbeans 7.0.1, glassfish 3.1.1, atmosphere 0.8.1, jersey 1.11. I
searched the web an tried any possible solution but nothing helped.
