<h1>Embedded JMS Server Example</h1>
|
||
|
|
|
||
|
|
<p>This examples shows how to setup and run an embedded JMS server using HornetQ.</p>
|
||
|
|
<p>HornetQ was designed using POJOs (Plain Old Java Objects) which means embedding HornetQ in your own application
|
||
|
|
is as simple as instantiating a few objects.</p>
|
||
|
|
<p>This example does not use any configuration files. The server is configured using POJOs and can be easily ported to any dependency injection framework.<br />
|
||
|
|
We will setup and run a full-fledged JMS server which binds its JMS resources to JNDI and can be accessed by remote clients.</p>
|
||
|
|
|
||
|
|
<h2>Example step-by-step</h2>
|
||
|
|
<p><i>To run the example, simply type <code>mvn verify</code> from this directory</i></p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Create HornetQ core configuration, and set the properties accordingly</li>
|
||
|

<pre class="prettyprint">
|

<code>Configuration configuration = new ConfigurationImpl();

jmsConfig.getConnectionFactoryConfigurations().add(cfConfig);</code>
|

</pre>
|

|
|

<li>Configure the JMS Queue</li>

jmsServer.start();</code>
|

|
</pre>
|
||
|
|
|
||
|
|
<p>At this point the JMS server is started and any JMS clients can look up JMS resources from JNDI to send/receive
|
||
|
|
messages from the server. To keep the example simple, we will send and receive a JMS message from the same JVM
|
||
|
|
used to run the JMS server.</p>
|
||
|
|
|
||
|
|
<li>Lookup JMS resources defined in the configuration </li>
|
||
|
|
<pre class="prettyprint">
|
||
|
|
<code>ConnectionFactory cf = (ConnectionFactory)context.lookup("/cf");
|
||
|
|
Queue queue = (Queue)context.lookup("/queue/queue1");</code>
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<li>Send and receive a message using JMS API</li>
|
||
|
|
<p>See the <a href="../../queue/readme.html">Queue Example</a> for detailed steps to send and receive a JMS message</p>
|
||
|
|
|
||
|
|
<p>Finally, we stop the JMS server and its associated resources.</p>
|

<li>Stop the JMS server</li>
