Chapter 23 888 The send() method in this example first sets the message text, then sends the message:   public void send(String msg) throws JMSException   {     // Set the message's text     message.setText(msg); The queueSender.send(Message message) method sends a message to the Sender's queue. The message parameter contains the message to be sent to the destination. In this case the destination is MyJMSQueue. Only one client that subscribes to MyJMSQueue will receive the message:     // Send the message     queueSender.send(message);   }   /**    * Closes JMS connection objects.    */   public void close() throws JMSException   {     queueSender.close();     queueSession.close();     queueConnection.close();   }   /**    * Writes messages to the queue until the user enters 'q' or 'Q'.    */   public static void main(String[] args) throws Exception   {     // Create a sender.     Sender sender = new Sender();     // Send user's messages until user enters an 'q' or 'Q'.     BufferedReader in = new BufferedReader(new InputStreamReader(System.in));     String msg = null;     do     {       // Get the message       System.out.print("Enter message ('q' or 'Q' quits): ");       msg = in.readLine();       // Publish message if it isn't empty.       if(msg.trim().length() != 0)       {         sender.send(msg);       }     }while(!msg.equalsIgnoreCase("q"));     // Close up the JMS connections     sender.close();   } } As you can see, this example is very similar to the Publisher from the Pub/Sub example above.
