QueueBrowser

[petera]

Hi,

I am using activemq ver 4.0.1 on a mac running OS x 10.4.8

I am trying to use the queue browser to view messages on a queue but it does
not seem to work. No messages
are being returned when i issue the command:
              Enumeration msgs = browser.getEnumeration();

There are definitely messages on the queue and i can see them in the
persistent activemq_msgs table.

Is this a bug ? Or am i doing something wrong ?

CODE:

               
        try
        {
/*
 * Create a JNDI API Initial Context object.
 */       
              InitialContext init = new InitialContext() ;
              Context envContext = (Context) init.lookup("java:comp/env") ;
/*
 * Look up Connection Factory and destination.
 */       
              ConnectionFactory connectionFactory = (ConnectionFactory)
envContext.lookup("jms/ConnectionFactory") ;
              
              Queue queue = (Queue) envContext.lookup("jms/InvoiceQueue") ;
          
              connection = connectionFactory.createConnection();

              session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
              
              QueueBrowser browser = session.createBrowser(queue);
              Enumeration msgs = browser.getEnumeration();

              if (!msgs.hasMoreElements()) {
                  out.println("No messages in queue");
              } else {
                  while (msgs.hasMoreElements()) {
                      Message tempMsg = (Message) msgs.nextElement();
                      out.println("Message: " + tempMsg);
                  }
              }
          } catch (JMSException e) {
              out.println("Exception occurred: " + e.toString());
          }
        catch (NamingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
              if (connection != null) {
                  try {
                      connection.close();
                  } catch (JMSException e) {
                  }
              }
          }
