+     <h1>JMS Message Priority Example</h1>
+     <br>
+     <p>This example shows how messages with priorities are delivered.</p>
+     
+     <p>Message Priority carries the delivery preference of messages. It can be retrieved by the message's
+     standard header field 'JMSPriority' as defined in JMS specification version 1.1. The value is of type
+     integer, ranging from 0 (the lowest) to 9 (the highest). When messages are being delivered, their priorities
+     will effect their order of delivery. Messages of higher priorities will likely be delivered before those 
+     of lower priorities. Messages of equal priorities are delivered in the natural order of their arrival at 
+     their destinations. Please consult the JMS 1.1 specification for full details.</p>
+     
+     <p>In this example, three messages are sent to a queue with different priorities. The first message is sent
+     with default priority (4), the second is sent with a higher priority (5), and the third has the highest
+     priority (9). At the receiving end, we will show the order of receiving of the three messages. You will 
+     see that the third message, though last sent, will 'jump' forward to be the first one received. The second 
+     is also received ahead of the message first sent, but behind the third message. The first message, regardless
+     of its being sent first, arrives last.</p>
+     
+     <br>
+     <h2>Example step-by-step</h2>
+     <p><i>To run the example, simply type <code>ant</code> from this directory</i></p>
+     <br>
+     <ol>
+        <li>First we need to get an initial context so we can look-up the JMS connection factory and destination objects from JNDI. This initial context will get it's properties from the <code>client-jndi.properties</code> file in the directory <code>../common/config</code></li>
+        <pre>
+           <code>InitialContext initialContext = getContext();</code>
+        </pre>
+
+        <li>We look-up the JMS queue object from JNDI</li>
+        <pre>
+           <code>Queue queue = (Queue) initialContext.lookup("/queue/exampleQueue");</code>
+        </pre>
+
+        <li>We look-up the JMS connection factory object from JNDI</li>
+        <pre>
+           <code>ConnectionFactory cf = (ConnectionFactory) initialContext.lookup("/ConnectionFactory");</code>
+        </pre>
+
+        <li>We create a JMS connection</li>
+        <pre>
+           <code>connection = cf.createConnection();</code>
+        </pre>
+
+        <li>We create a JMS session. The session is created as non transacted and will auto acknowledge messages.</li>
+        <pre>
+           <code>Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);</code>
+        </pre>
+
+        <li>We create a JMS message producer on the session. This will be used to send the messages.</li>
+        <pre>
+          <code>MessageProducer messageProducer = session.createProducer(topic);</code>
+       </pre>
+
+        <li>We Create a JMS Message Consumer.</li>
+        <pre>
+           <code>
+           MessageConsumer redConsumer = session.createConsumer(queue);
+           redConsumer.setMessageListener(new SimpleMessageListener());
+           </code>
+        </pre>
+
+        <li>We Create three messages.</li>
+        <pre>
+           <code>
+           TextMessage[] sentMessages = new TextMessage[3];
+           sentMessages[0] = session.createTextMessage("first message");
+           sentMessages[1] = session.createTextMessage("second message");
+           sentMessages[2] = session.createTextMessage("third message");
+           </code>
+        </pre>
+
+        <li>Send the Messages, each has a different priority.</li>
+        <pre>
+           <code>
+           producer.send(sentMessages[0]);
+           System.out.println("Message sent: " + sentMessages[0].getText() + " with priority: " + sentMessages[0].getJMSPriority());
+           producer.send(sentMessages[1], DeliveryMode.NON_PERSISTENT, 5, 0);
