<p><em>To run the example, simply type <code>mvn verify</code> from this directory</em></p>
<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 its properties from <ahref="server0/client-jndi.properties">client-jndi.properties</a></li>
<li>We create a JMS text message that we are going to send.</li>
<preclass="prettyprint">
<code>TextMessage message = session.createTextMessage("This is a text message");</code>
</pre>
<li>We send message to the queue</li>
<preclass="prettyprint">
<code>messageProducer.send(message);</code>
</pre>
<p><em>Now that we have a message in the queue, we will manage the queue by retrieving the number of messages in the queue
(i.e. 1) and by removing the message which has been sent in step 8.</em></p>
<li>We retrieve the <code>ObjectName</code> corresponding to the queue using a helper class <code>ObjectNameBuilder</code></li>
<preclass="prettyprint">
<code>ObjectName on = ObjectNameBuilder.DEFAULT.getJMSQueueObjectName(queue.getQueueName());</code>
</pre>
<li>We create a JMX Connector to connect to the server's MBeanServer using the <ahref="http://java.sun.com/j2se/1.5.0/docs/guide/management/agent.html#connecting">standard JMX service URL</a></li>
<preclass="prettyprint">
<code>JMXConnector connector = JMXConnectorFactory.connect(new JMXServiceURL(JMX_URL), new HashMap());</code>
</pre>
<li>We retrieve a <code>MBeanServerConnection</code> from the JMX connector</li>
<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>
<preclass="prettyprint">
<code>finally
{
if (initialContext != null)
{
initialContext.close();
}
if (connection != null)
{
connection.close();
}
}</code>
</pre>
</ol>
