+ <body>
+ <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);
+ System.out.println("Message sent: " + sentMessages[1].getText() + "with priority: " + sentMessages[1].getJMSPriority());
+ producer.send(sentMessages[2], DeliveryMode.NON_PERSISTENT, 9, 0);
+ System.out.println("Message sent: " + sentMessages[2].getText() + "with priority: " + sentMessages[2].getJMSPriority());
+ </code>
+ </pre>
+
+ <li>We start the connection now.</li>
+ <pre>
+ <code>
+ connection.start();
+ </code>
+ </pre>
+
+ <li>We wait for message delivery completion</li>
+ <pre>
+ <code>
+ Thread.sleep(5000);
+ </code>
+ </pre>
+
+ <li>We wait for message delivery completion</li>
+ <pre>
+ <code>
+ for (int i = 0; i < 3; i++)
+ {
+ TextMessage rm = msgReceived.get(i);
+ if (!rm.getText().equals(sentMessages[2-i].getText()))
+ {
+ System.err.println("Priority is broken!");
+ result = false;
+ }
+ }
+ </code>
+ </pre>
+
+ <li>And finally, <b>always</b> remember to close your JMS connections and resources after use, in a <code>finally</code> block. Closing a JMS connection will automatically close all of its sessions, consumers, producer and browser objects</li>
+
+ <pre>
+ <code>finally
+ {
+ if (initialContext != null)
+ {
+ initialContext.close();
+ }
+ if (connection != null)
+ {
+ connection.close();
+ }
+ }</code>
