Возвращения JSONP для запроса взвешенного Atmosphere

Question

У меня есть сервлет, который имеет метод суспендирующего и передающие один:

@GET 
    @Path("/notification") 
    @Produces({ "application/x-javascript", MediaType.APPLICATION_JSON }) 
    @Suspend 
    public JSONWithPadding getNextNotification(
    @QueryParam("callback") @DefaultValue("callback") String callback) { 

    Random random = new Random(); 

    Notification n = new Notification(); 
    n.setMessage("Message is " + Long.toHexString(random.nextLong())); 
    n.setMessage("S-" + Long.toHexString(random.nextLong())); 

    return new JSONWithPadding(n, callback); 

    } 

Я призываю это из браузера и увидеть следующий хороший выход в моем браузере:

<!-- ---------------------------------------------------------------- http://github.com/Atmosphere ------------------------------------------------------------------------ --> 
<!-- Welcome to the Atmosphere Framework..... 
<!-- --------------------------------------------------------------------------------------------------------------------------------------------------------------------- --> 
<!-- EOD -->callback({"message":"S-c897404ad5703dcc","sender":null} 

Итак, моя цель хорошо сериализована для JSONP.

Теперь я называю мой метод вещателя:

@Context Broadcaster bc; 

    @Broadcast({JsonpFilter.class}) 
    @GET 
    @Path("/broadcast5") 
    public Broadcastable broadcast5() { 
    Random random = new Random(); 
    Notification n = new Notification(); 
    n.setMessage("Message is " + Long.toHexString(random.nextLong())); 
    n.setMessage("S-" + Long.toHexString(random.nextLong())); 
    return new Broadcastable(new JSONWithPadding(n, "callback111"), bc); 
    } 

На стороне сервера я получаю следующее исключение и ничего вещают:

Как я могу сделать мою вещательную работу? Нужно ли мне возвращать объект JSONWithPadding или только POJO?

Answer 1

Вы получаете AbstractMethodError. У вас есть атмосфера в вашем классе?
