In same file we can change the remote port specified in netty connector.
Keep all properties inside a JmsContext:
public class JmsContext { public static final String FILE_NAME_ATTRIBUTE = "FILE_NAME"; public static final String FILE_CODE_ATTRIBUTE = "FILE_CODE"; private String initialContextFactory; private String remoteConnectionfactoryUrl; private String importQueueUrl; private String serverUrl; private String userName; private String password"; private String fileName; private String fileCode; private byte[] bytes; // getters and setters }
Create a JmsHelper class to send the message:
import org.apache.log4j.Logger; import javax.jms.*; import javax.naming.Context; import javax.naming.InitialContext; import java.io.File; import java.util.Properties; public class JmsHelper { private static final Logger LOG = Logger.getLogger(JmsHelper.class); public static void sendMessage(JmsContext jmsContext) { Connection connection = null; Session session = null; MessageProducer msgProducer = null; try { LOG.info("Running " + JmsHelper.class.toString() + " on current path " + new File(".").getAbsolutePath()); LOG.info("Publishing " + jmsContext.getFileName() + " to destination '" + jmsContext.getImportQueueUrl() + "'\n"); final Properties initialContextProperties = new Properties(); initialContextProperties.put(Context.INITIAL_CONTEXT_FACTORY, jmsContext.getInitialContextFactory()); initialContextProperties.put(Context.PROVIDER_URL, jmsContext.getServerUrl()); initialContextProperties.put(Context.SECURITY_PRINCIPAL, jmsContext.getUserName()); initialContextProperties.put(Context.SECURITY_CREDENTIALS, jmsContext.getPassword()); final InitialContext ic = new InitialContext(initialContextProperties); LOG.info("Initial context created."); ConnectionFactory factory = (ConnectionFactory)ic.lookup( jmsContext.getRemoteConnectionfactoryUrl()); LOG.info("Connection " + jmsContext.getRemoteConnectionfactoryUrl() + "factory acquired."); final Queue queue = (Queue) ic.lookup(jmsContext.getImportQueueUrl()); LOG.info("Found queue: " + jmsContext.getImportQueueUrl()); connection = factory.createConnection(jmsContext.getUserName(), jmsContext.getPassword()); session = connection.createSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE); msgProducer = session.createProducer(queue); BytesMessage msg = session.createBytesMessage(); msg.setStringProperty(ImportJmsContext.FILE_NAME_ATTRIBUTE, jmsContext.getFileName()); msg.setStringProperty(ImportJmsContext.FILE_CODE_ATTRIBUTE, jmsContext.getFileCode()); msg.writeBytes(jmsContext.getBytes()); msgProducer.send(msg); LOG.info("Bytes file message was published to server."); } catch (Exception e) { e.printStackTrace(); } finally { if (connection != null) { try { connection.close(); } catch (JMSException e) { e.printStackTrace(); } } } } }
Create the test class that connects directly to the Hornetq server (see server url and inital context factory class):
import javax.jms.JMSException; import java.io.File; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; public class JmsHornetqTest { private String fileName = "..."; private String filePath = "..."; private String fileCode = "E1"; private String serverUrl = "jnp://localhost:1099";//"remote://localhost:5445"; private String initialContextFactory = "org.jnp.interfaces.NamingContextFactory"; private String remoteConnectionFactoryUrl = "/ConnectionFactory"; private String hornetqUser = "guest"; private String hornetqPassword = "guest"; private String hornetqImportQueueUrl = "/queue/testQueue"; public void sendMessage() { try { ImportJmsContext jmsContext = new ImportJmsContext(); jmsContext.setServerUrl(serverUrl); jmsContext.setUserName(hornetqUser); jmsContext.setPassword(hornetqPassword); jmsContext.setRemoteConnectionfactoryUrl(remoteConnectionFactoryUrl); jmsContext.setInitialContextFactory(initialContextFactory); jmsContext.setImportQueueUrl(hornetqImportQueueUrl); jmsContext.setFileName(fileName); jmsContext.setFileCode(fileCode); jmsContext.setBytes(getBytes()); ImportJmsHelper.sendMessage(jmsContext); } catch (Exception e) { e.printStackTrace(); } } private byte[] getBytes() throws IOException { Path fileLocation = Paths.get(filePath + File.separator + fileName); return Files.readAllBytes(fileLocation); } public static void main(String[] args) throws JMSException { new JmsHornetqTest().sendMessage(); } }
Now the only thing we need to do is to configure (jms-context.xml) the hornetq in our Wildfly server to listen and receive the bytes message (we do not specify the destination , but the destination name from hornetq server and a destination resolver):
<bean id="jmsHQImportConnectionFactory" lazy-init="true" class="org.hornetq.jms.client.HornetQConnectionFactory"> <constructor-arg value="true"/> <constructor-arg> <list> <bean class="org.hornetq.api.core.TransportConfiguration"> <constructor-arg value="org.hornetq.core.remoting.impl.netty.NettyConnectorFactory"/> <constructor-arg> <map key-type="java.lang.String" value-type="java.lang.Object"> <entry key="host" value="localhost"/> <entry key="port" value="5445"/> </map> </constructor-arg> </bean> <!-- more beans if we have backup servers --> </list> </constructor-arg> <property name="reconnectAttempts" value="-1"/> <property name="failoverOnInitialConnection" value="true"/> <property name="initialConnectAttempts" value="15"/> <property name="consumerWindowSize" value="0"/> </bean> <bean id="jmsHQImportConnectionFactoryProxy" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter"> <property name="targetConnectionFactory" ref="jmsHQImportConnectionFactory" /> <property name="username" value="guest" /> <property name="password" value="guest" /> </bean> <bean id="jmsHQImportTransactionManager" class="org.springframework.jms.connection.JmsTransactionManager"> <property name="connectionFactory" ref="jmsHQImportConnectionFactoryProxy"/> </bean> <bean id="jmsHQImportDestinationResolver" class="org.springframework.jms.support.destination.JndiDestinationResolver"> <property name="cache" value="true"/> <property name="fallbackToDynamicDestination" value="true"/> </bean> <bean id="jmsHQImportMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="concurrentConsumers" value="1"/> <property name="connectionFactory" ref="jmsHQImportConnectionFactoryProxy"/> <property name="transactionManager" ref="jmsHQImportTransactionManager"/> <property name="destinationName" value="testQueue"/> <property name="destinationResolver" ref="jmsHQImportDestinationResolver"/> <property name="messageListener" ref="jmsImportMessageListener"/> </bean>
