+ <h1>JBoss Messaging JMS Automatic Failover Example</h1>
+ <br>
+ <p>This example demonstrates a JMS queue deployed on two different nodes. The two nodes are configured to form a cluster.</p>
+ <p>We then create a consumer on the queue on each node, and we create a producer on only one of the nodes.</p>
+ <p>We then send some messages via the producer, and we verify that <b>both</b> consumers receive the sent messages
+ in a round-robin fashion.</p>
+ <p>In other words, JBoss Messaging <b>load balances</b> the sent messages across all consumers on the cluster</p>
+ <p>This example uses JNDI to lookup the JMS Queue and ConnectionFactory objects. If you prefer not to use
+ JNDI, these could be instantiated directly.</p>
+ <p>Here's the relevant snippet from the server configuration, which tells the server to form a cluster between the two nodes
+ and to load balance the messages between the nodes.</p>
+ <pre>
+ <code>
+ <cluster-connection name="my-cluster">
+ <address>jms</address>
+ <retry-interval>500</retry-interval>
+ <use-duplicate-detection>true</use-duplicate-detection>
+ <forward-when-no-consumers>true</forward-when-no-consumers>
+ <max-hops>1</max-hops>
+ <discovery-group-ref discovery-group-name="my-discovery-group"/>
+ </cluster-connection>
+ </code>
+ </pre>
+ <p>For more information on JBoss Messaging load balancing, and clustering in general, please see the clustering
+ section of the user manual.</p>
+ <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> Get an initial context for looking up JNDI from server 0.</li>
+ <pre>
+ <code>
+ ic0 = getContext(0);
+ </code>
+ </pre>
+
+ <li>Look-up the JMS Queue object from JNDI</li>
+ <pre>
+ <code>Queue queue = (Queue)ic0.lookup("/queue/exampleQueue");</code>
+ </pre>
+
+ <li>Look-up a JMS Connection Factory object from JNDI on server 0</li>
+ <pre>
+ <code>ConnectionFactory cf0 = (ConnectionFactory)ic0.lookup("/ConnectionFactory");</code>
+ </pre>
+
+ <li>Get an initial context for looking up JNDI from server 1.</li>
+ <pre>
+ <code>ic1 = getContext(1);</code>
+ </pre>
+
+ <li>Look-up a JMS Connection Factory object from JNDI on server 1</li>
+ <pre>
+ <code>ConnectionFactory cf1 = (ConnectionFactory)ic1.lookup("/ConnectionFactory");
+ </code>
+ </pre>
+
+ <li>We create a JMS Connection connection0 which is a connection to server 0</li>
+ <pre>
+ <code>
+ connection0 = cf0.createConnection();
+ </code>
+ </pre>
+
+ <li>We create a JMS Connection connection1 which is a connection to server 1</li>
+ <pre>
+ <code>
+ connection1 = cf1.createConnection();
+ </code>
+ </pre>
+
+ <li>We create a JMS Session on server 0</li>
+ <pre>
+ <code>
+ Session session0 = connection0.createSession(false, Session.AUTO_ACKNOWLEDGE);
+ </code>
+ </pre>
+
+ <li>We create a JMS Session on server 1</li>
+ <pre>
+ <code>
+ Session session1 = connection1.createSession(false, Session.AUTO_ACKNOWLEDGE);
+ </code>
+ </pre>
+
+ <li>We start the connections to ensure delivery occurs on them</li>
+ <pre>
+ <code>
+ connection0.start();
+
+ connection1.start();
+ </code>
+ </pre>
+
+ <li>We create JMS MessageConsumer objects on server 0 and server 1</li>
+ <pre>
+ <code>
+ MessageConsumer consumer0 = session0.createConsumer(queue);
+
+ MessageConsumer consumer1 = session1.createConsumer(queue);
+ </code>
+ </pre>
+
+ <li>We create a JMS MessageProducer object on server 0.</li>
+ <pre>
+ <code>
+ MessageProducer producer = session0.createProducer(queue);</code>
+ </pre>
+
+ <li>We send some messages to server 0.</li>
+ <pre>
+ <code>
+ final int numMessages = 10;
+
+ for (int i = 0; i < numMessages; i++)
+ {
+ TextMessage message = session0.createTextMessage("This is text message " + i);
+
+ producer.send(message);
+
+ System.out.println("Sent message: " + message.getText());
+ }
+ </code>
+ </pre>
+
+ <li>We now consume those messages on *both* server 0 and server 1.
+ We note the messages have been distributed between servers in a round robin fashion.
+ JBoss Messaging has <b>load balanced</b> the messages between the available consumers on the different nodes.
+ JBoss Messaging can be configured to always load balance messages to all nodes, or to only balance messages
+ to nodes which have consumers with no or matching selectors. See the user manual for more details.</li>
+ JMS Queues implement point-to-point message where each message is only ever consumed by a
+ maximum of one consumer.
+ <pre>
+ <code>
+ for (int i = 0; i < numMessages; i += 2)
+ {
+ TextMessage message0 = (TextMessage)consumer0.receive(5000);
+
+ System.out.println("Got message: " + message0.getText() + " from node 0");
+
+ TextMessage message1 = (TextMessage)consumer1.receive(5000);
+
+ System.out.println("Got message: " + message1.getText() + " from node 1");
+ }
+ </code>
+ </pre>
+
+ <li>And finally (no pun intended), <b>always</b> remember to close your JMS 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 (connection0 != null)
+ {
+ connection0.close();
+ }
+
+ if (connection1 != null)
+ {
+ connection1.close();
+ }
+ }
+ </code>
+ </pre>
+
+ </ol>
