title: TIBCO JMS Queue message reciever gets stuck
body: <p>Hi I have created the below class to read messages off a jibco jms queue. In a different class I create an instance of this class and try to getMessage() into a stirng. I have placed a message in the queue, My application gets stuck as I call the getMessage() method... Any idea ? or an improvement I could add to below class? </p>
  
  <pre><code>public class EMSReceiver {
  
      private QueueConnection connection;
      private QueueReceiver queueReceiver;
      private Queue queue;
  
      private TextMessage message;
  
      public EMSReceiver(String initialContextFactory, String userName, String password, String serverUrl, String confact, String q){
          try {
  
              Properties env = new Properties();
              env.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
              env.put(Context.SECURITY_PRINCIPAL, userName);
              env.put(Context.SECURITY_CREDENTIALS, password);
              env.put(Context.PROVIDER_URL, serverUrl);
  
              InitialContext jndi = new InitialContext(env);
  
              QueueConnectionFactory connectionFactory = (QueueConnectionFactory) jndi.lookup(confact);
              QueueConnection connection = connectionFactory.createQueueConnection(userName, password);
              QueueSession session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
              this.queue = (Queue) jndi.lookup(q);
              this.queueReceiver = session.createReceiver(queue);
  
              connection.start();
  
          }
          catch (JMSException e) {
              e.printStackTrace();
              System.exit(0);
          } catch (NamingException e) {
              e.printStackTrace();
          }
      }
  
      public String getMessage() throws JMSException{
  
          try {
              this.message = (TextMessage) queueReceiver.receive();
          } catch (JMSException e) {
              System.out.println("Could not retrieve the message.");
              e.printStackTrace();
          }
          return message.getText();
  
      }
