+     <h1>JBoss Messaging JMS Message Producer Rate Limiting</h1>
+     <br>
+     <p>With JBoss Messaging you can specify a maximum send rate at which a JMS MessageProducer will send messages.
+     This can be specified when creating or deploying the connection factory. See <code>jbm-jms.xml</code></p>
+     <p>If this value is specified then JBoss Messaging will ensure that messages are never produced at a rate higher than
+     the specified rate. This is a form of producer <i>throttling</i>.</p>     
+     <h2>Example step-by-step</h2>
+     <p>In this example we specify a <code>producer-max-rate</code> of <code>50</code> messages per second in the <code>jbm-jms.xml</code>
+     file when deploying the connection factory:</p>
+     <pre>
+     <code>
+   &lt;connection-factory name="ConnectionFactory"&gt;
+      &lt;connector-ref connector-name="netty-connector"/&gt;
+      &lt;entries&gt;
+         &lt;entry name="ConnectionFactory"/&gt;       
+      &lt;/entries&gt;
+      
+      &lt;!-- We limit producers created on this connection factory to produce messages at a maximum rate
+      of 50 messages per sec --&gt;
+      &lt;producer-max-rate&gt;50&lt;/producer-max-rate&gt;
+      
+   &lt;/connection-factory&gt;
+     </code>
+     </pre>
+     <p>We then simply send as many messages as we can in 10 seconds and note how many messages are actually sent.</p>
+     <p>We note that the number of messages sent per second never exceeds the specified value of <code>50</code> messages per second.</p>
+     <br>
+     <p><i>To run the example, simply type <code>ant</code> from this directory</i></p>
+     <br>
+     <ol>
+        <li>Create an initial context to perform the JNDI lookup.</li>
+        <pre>
+           <code>initialContext = getContext(0);</code>
+        </pre>
+
+        <li>Perfom a lookup on the queue</li>
