Atmosfera não pode obter session no Glassfish 3.1.2

Eu obtive o exemplo de bate – papo trabalhando no Atmosphere e agora quero obter a session, mas recebo uma exceção de ponteiro nulo. Minha configuração:

  • GlassFish 3.1.2
  • Atmosfera 1.0.0-SNAPSHOT

Meu arquivo ChatAtmosphereHandler.java:

@Override public void onRequest(AtmosphereResource r) throws IOException { AtmosphereRequest req = r.getRequest(); // First, tell Atmosphere to allow bi-directional communication by suspending. if (req.getMethod().equalsIgnoreCase("GET")) { /* ------- ADDED LINES BY ME ------- */ double i = Math.random(); System.out.println(i); req.getSession(true).setAttribute("user", i); //Null pointer exception /* --------------------------------- */ // The negotiation header is just needed by the sample to list all the supported transport. if (req.getHeader("negotiating") == null) { r.suspend(); } else { r.getResponse().getWriter().write("OK"); } // Second, broadcast message to all connected users. } else if (req.getMethod().equalsIgnoreCase("POST")) { r.getBroadcaster().broadcast(req.getReader().readLine().trim()); } } 

E o rastreamento de pilha de exceção:

O código de manipulação de session foi modificado desde então. Por favor, tente novamente com o último código mestre.
