<h1>Embedded JMS Server Example</h1>
<p>This examples shows how to setup and run an embedded JMS server using ActiveMQ.</p>
<p>ActiveMQ was designed using POJOs (Plain Old Java Objects) which means embedding ActiveMQ 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 ActiveMQ core configuration, and set the properties accordingly</li>
<pre class="prettyprint">
<code>Configuration configuration = new ConfigurationImpl();
configuration.setPersistenceEnabled(false);
configuration.setSecurityEnabled(false);
configuration.getAcceptorConfigurations().add(new TransportConfiguration(NettyAcceptorFactory.class.getName()));</code>
Configuration configuration = new ConfigurationImpl();</pre>
<li>Create the ActiveMQ core server</li>
<pre class="prettyprint">
<code>ActiveMQServer hornetqServer = ActiveMQ.newActiveMQServer(configuration);</code>
</pre>
<li>Create and start the JNDI server (using JBoss JNDI implementation)</li>
<pre class="prettyprint">
<code>System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
NamingBeanImpl naming = new NamingBeanImpl();
naming.start();
Main jndiServer = new Main();
jndiServer.setNamingInfo(naming);
jndiServer.setPort(1099);
jndiServer.setBindAddress("localhost");
jndiServer.setRmiPort(1098);
jndiServer.setRmiBindAddress("localhost");
jndiServer.start();</code>
</pre>
<li>Create the JMS configuration</li>
<pre class="prettyprint">
<code>JMSConfiguration jmsConfig = new JMSConfigurationImpl();</code>
</pre>
<li>Configure context used to bind the JMS resources to JNDI</li>
<pre class="prettyprint">
<code>Hashtable<String, String> env = new Hashtable<String, String>();
env.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.provider.url", "jnp://localhost:1099");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
Context context = new InitialContext(env);
jmsConfig.setContext(context);</code>
</pre>
<li>Configure the JMS ConnectionFactory</li>
<pre class="prettyprint">
<code>TransportConfiguration connectorConfig = new TransportConfiguration(NettyConnectorFactory.class.getName());
ConnectionFactoryConfiguration cfConfig = new ConnectionFactoryConfigurationImpl("cf", connectorConfig, "/cf");
jmsConfig.getConnectionFactoryConfigurations().add(cfConfig);</code>
</pre>
<li>Configure the JMS Queue</li>
<pre class="prettyprint">
<code>QueueConfiguration queueConfig = new QueueConfigurationImpl("queue1", null, false, "/queue/queue1");
jmsConfig.getQueueConfigurations().add(queueConfig);</code>
</pre>
<li>Start the JMS Server using the ActiveMQ core server and the JMS configuration</li>
<pre class="prettyprint">
<code>JMSServerManager jmsServer = new JMSServerManagerImpl(hornetqServer, jmsConfig);
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>
<pre class="prettyprint">
<code>jmsServer.stop();</code>
</pre>
<li>Stop the JNDI server</li>
<pre class="prettyprint">
<code>naming.stop();
jndiServer.stop();</code>
</pre>
</ol>
