<h1>JMS Load Balanced Clustered Queue Example</h1>
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
<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, ActiveMQ Artemis <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 class="prettyprint">
<code>&lt;cluster-connection name="my-cluster"&gt;
&lt;connector-ref>netty-connector&lt;/connector-ref>
&lt;retry-interval&gt;500&lt;/retry-interval&gt;
&lt;use-duplicate-detection&gt;true&lt;/use-duplicate-detection&gt;
&lt;message-load-balancing&gt;STRICT&lt;/message-load-balancing&gt;
&lt;max-hops&gt;1&lt;/max-hops&gt;
&lt;discovery-group-ref discovery-group-name="my-discovery-group"/&gt;
&lt;/cluster-connection&gt;
</code>
</pre>
<p>For more information on ActiveMQ Artemis load balancing, and clustering in general, please see the clustering
section of the user manual.</p>
