    Have a node wait for JMS message - Problem

    Brett Anthoine Newbie

      Hello everyone,

      I have a node in my process that I want to wait on a jms message. I'm using the following code:

      package ch.siesa.beyondfibre.jbpm.customer.delete;
      
      import javax.jms.*;
      import javax.naming.*;
      
      import org.jbpm.graph.def.ActionHandler;
      import org.jbpm.graph.exe.ExecutionContext;
      
      public class WaitAction implements ActionHandler, MessageListener{
      
       private static final long serialVersionUID = 1L;
      
       Context jndiContext = null;
       ExecutionContext executionContext = null;
       TopicConnectionFactory topicConnectionFactory = null;
       TopicConnection topicConnection = null;
       TopicSession topicSession = null;
       Topic topic = null;
       TopicSubscriber topicSubscriber = null;
      
       public void execute(ExecutionContext ctx) throws Exception {
       System.out.println("Subscribing node to JMS topic...");
       this.executionContext = ctx;
       jndiContext = new InitialContext();
       topicConnectionFactory = (TopicConnectionFactory)jndiContext.lookup("TopicConnectionFactory");
       topic = (Topic) jndiContext.lookup("topic/testTopic");
       topicConnection = topicConnectionFactory.createTopicConnection();
       topicSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
       topicSubscriber = topicSession.createSubscriber(topic);
       topicSubscriber.setMessageListener(this);
       topicConnection.start();
       System.out.println("Subscription ok, waiting !");
       }
      
       public void onMessage(Message message) {
       executionContext.leaveNode("success");
       }
      
      
      }
      


      It is however throwing an exception:

      11:09:44,983 ERROR [GraphElement] action threw exception: This method is not applicable inside the application server. See the J2EE spec, e.g. J2EE1.4 Section 6.6
      javax.jms.IllegalStateException: This method is not applicable inside the application server. See the J2EE spec, e.g. J2EE1.4 Section 6.6

      I have two questions :
      - Is there a workaround this exception ?
      - Isn't there a simpler way to have a node wait for a message ?

      Thanking you all in advance :)

      Regards
