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(); configuration.setPersistenceEnabled(false); configuration.setSecurityEnabled(false); configuration.getAcceptorConfigurations().add(new TransportConfiguration(NettyAcceptorFactory.class.getName()));</code> Configuration configuration = new ConfigurationImpl();</pre> <li>Create the HornetQ core server</li> <pre class="prettyprint"> <code>HornetQServer hornetqServer = HornetQ.newHornetQServer(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 HornetQ 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> </body> </html>
