<h1>Embedded Example</h1>
|
|
|
|
<p>This example shows how to setup and run ActiveMQ Artemis embedded.</p>
|
|
<p>ActiveMQ Artemis was designed to use POJOs (Plain Old Java Objects), what makes embedding ActiveMQ Artemis as simple as instantiating a few objects.</p>
|
|
<p>In this example, we are using two jars:</p>
|
|
<ul>
|
|
<li>activemq-server.jar</li>
|
|
<li>netty.jar</li>
|
|
</ul>
|
|
|
|
<p>ActiveMQ Artemis Embedded could be used from very simple use cases with only InVM support to very complex cases with clustering, persistence and fail over.</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>
|
|
<p>In this we don't use any configuration files. (Everything is embedded). We simply instantiate ConfigurationImpl, ActiveMQServer, start it and operate on JMS regularly</p>
|
|
|
|
<ol>
|
|
<li>Create the Configuration, and set the properties accordingly</li>
|
|
<pre class="prettyprint">
|
|
Configuration configuration = new ConfigurationImpl();
|
|
configuration.setEnablePersistence(false);
|
|
configuration.setSecurityEnabled(false);
|
|
configuration.getAcceptorConfigurations().add(new TransportConfiguration(InVMAcceptorFactory.class.getName()));
|

<li>Create and start the server</li>
