<h1>Proton qpid java example</h1>
<<p>HornetQ is a multi protocol broker. It will inspect the initial handshake of clients to determine what protocol to use.</p>
<p>All you need to do is to connect a client into hornetq's configured port and you should be able connect.</p>
<p>To run this example simply run the command <literal>mvn verify</literal>, execute the compile.sh script and start the executable called ./hello</p>
<p>You don't need to do anything special to configure the HornetQ server to accept AMQP clients. </p>
<p>Just for the sake of documentation though we are setting the port of HornetQ on this example as 5672 which is the port qpid have by default. </p>
<p>This is totally optional and you don't need to follow this convention. You can use any port you chose including HornetQ's 5445 default port</p>

<h2>Example step-by-step</h2>
<ol>
<li> Create an amqp qpid 1.0 connection.</li>
<pre class="prettyprint">
<code>connection= new Connection("localhost", 5672, null, null);</code>
</pre>
<li>Create a session</li>
<pre class="prettyprint">
<code>Session session = connection.createSession();</code>
</pre>
<li>Create a sender</li>
<pre class="prettyprint">
<code>Sender sender = session.createSender("testQueue");</code>
</pre>
<li>send a simple message</li>
<pre class="prettyprint">
<code>sender.send(new Message("I am an amqp message"));</code>
</pre>
<li>create a moving receiver, this means the message will be removed from the queue</li>
<pre class="prettyprint">
<code>Receiver rec = session.createMovingReceiver("testQueue");</code>
</pre>
<li>set some credit so we can receive</li>
<pre class="prettyprint">
<code>rec.setCredit(UnsignedInteger.valueOf(1), false);</code>
</pre>
<li>receive the simple message</li>
<pre class="prettyprint">
<code>Message m = rec.receive(5000);
System.out.println("message = " + m.getPayload());</code>
</pre>
<li>acknowledge the message</li>
<pre class="prettyprint">
<code>rec.acknowledge(m);</code>
</pre>
<li>close the connection</li>
<pre class="prettyprint">
<code>connection.close();</code>
</pre>
</ol>
