Clebert Suconic f509c075c6 ACTIVEMQ6-1 Artemis rename
This commit is a simple mv of the files.. We required two commits to preserve history,
one to git mv, one for the actual changes...

otherwise history would be lost

Based on the Apache ActiveMQ community vote this project is being
renamed "Artemis."

     <h1>JMS OpenWire Example</h1>

     <p>This example shows you how to configure ActiveMQ server to communicate with an ActiveMQ JMS client using ActiveMQ's native openwire protocol.</p>

     <h2>Example step-by-step</h2>
     <p><i>To run the example, simply type <code>mvn verify -Pexample</code> from this directory</i></p>

     <ol>
        <li>First we need to create an ActiveMQ connection factory.</code></li>
        <pre class="prettyprint">
           <code>ConnectionFactory factory = new ActiveMQConnectionFactory(urlString);</code>
        </pre>

        <li>Create the target queue</li>
        <pre class="prettyprint">
           <code>Queue queue = new ActiveMQQueue("exampleQueue");</code>
        </pre>

        <li>We create a JMS connection and start it</li>
        <pre class="prettyprint">
           <code>connection = cf.createConnection();</code>
           <code>connection.start()</code>
        </pre>

        <li>We create a JMS session. The session is created as non transacted and will auto acknowledge messages.</li>
        <pre class="prettyprint">
           <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 class="prettyprint">
          <code>MessageProducer messageProducer = session.createProducer(topic);</code>
       </pre>

        <li>We create a JMS text message that we are going to send.</li>
        <pre class="prettyprint">
           <code>TextMessage message = session.createTextMessage("This is a text message");</code>
        </pre>

        <li>We send message to the queue</li>
        <pre class="prettyprint">
           <code>messageProducer.send(message);</code>
        </pre>

        <li>We create a JMS Message Consumer to receive the message.</li>
          <pre class="prettyprint">
           <code>MessageConsumer messageConsumer = session.createConsumer(queue);</code>
        </pre>

        <li>The message arrives at the consumer. In this case we use a timeout of 5000 milliseconds but we could use a blocking 'receive()'</li>
        <pre class="prettyprint">
           <code>TextMessage messageReceived = (TextMessage) messageConsumer.receive(5000);</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 class="prettyprint">
           <code>finally
           {
              if (connection != null)
              {
                 connection.close();
              }
           }</code>
        </pre>
