    RF 4.1 cr2 CDI push demo doesn't work

    Daniel Yang Novice

      I just  created a maven project to test CDI push, but it can't work, the project run well, but can not send messages to consumer, and I found that the message reached the method TopicsContext.publish, but the getTopic(resolvedKey) returns null, I don't know why.

       

        public void publish(TopicKey key, Object data) throws MessageException {
              TopicKey resolvedKey = getTopicKeyWithResolvedExpressions(key);

              Topic topic = getTopic(resolvedKey);
              System.out.println("=====================");
              System.out.println("topic = " + topic);
              System.out.println("=====================");
              if (topic == null) {
                  throw new MessageException(MessageFormat.format("Topic {0} not found", resolvedKey.getTopicName()));
              }

              topic.publish(resolvedKey, data);
          }

       

      I've tried changed the version of atmosphere to 0.8RC2 or 0.8.1, when I request consumer.jsf page, it shows me can't find the class SocketSupport.

       

      Netbeans 7.0 IDE + Mojarra 2.1.3 (FCS b02) + RF 4.1 cr2 Glassfish 3.1.1

            Hi, you need the atmosphere-runtime.jar(v0.7.2) and related jars(atmosphere-compat-weblogic-0.7.2.jar, atmosphere-compat-tomcat-0.7.2.jar,atmosphere-compat-jbossweb-0.7.2.jar)

              I downloaded the demo source, I found that I should initialize the topics or set jms topics in your j2ee server myself. now I  add some lines in PushBean.java like following, it works fine but with some atmoshere servlet excetion that I don't care.

               

                  @PostConstruct
                  public void initialize() {
                      if (this.userIdentifier == null) {
                          this.userIdentifier = getUUID().replace("-", "");
                      }


                      TopicsContext topicsContext = TopicsContext.lookup();
                      Topic pushJmsTopic = topicsContext.getOrCreateTopic(new TopicKey(PUSH_CDI_TOPIC));
                      pushJmsTopic.setMessageDataSerializer(DefaultMessageDataSerializer.instance());
                  }

              Maybe we should set the pushbean to initialized eagerly, because someone request consumer page first than the bean initialized.

               

              In demo source it is initialized using a single thread, in my opinion, it is just used to wait jms topics initialized.
