I wanted to send/import a file using JMS to a Wildfly server application. To be able to do this I needed to do the following:
1. Add user "test" and password "test@1975" as an Application User to wildfly server using add-user script from bin. We must select yes for user used for one AS process to another.
2. Configure standalone-full.xml
Here it is defined the messaging-activemq subsystem:
<subsystem xmlns="urn:jboss:domain:messaging-activemq:1.0">
<server name="default">
<security-setting name="#">
<role name="guest" delete-non-durable-queue="true"
create-non-durable-queue="true"
consume="true" send="true"/>
</security-setting>
<address-setting name="#" message-counter-history-day-limit="10"
page-size-bytes="2097152" max-size-bytes="10485760"
expiry-address="jms.queue.ExpiryQueue"
dead-letter-address="jms.queue.DLQ"/>
<http-connector name="http-connector" endpoint="http-acceptor"
socket-binding="http"/>
<http-connector name="http-connector-throughput"
endpoint="http-acceptor-throughput" socket-binding="http">
<param name="batch-delay" value="50"/>
</http-connector>
<in-vm-connector name="in-vm" server-id="0"/>
<http-acceptor name="http-acceptor" http-listener="default"/>
<http-acceptor name="http-acceptor-throughput" http-listener="default">
<param name="batch-delay" value="50"/>
<param name="direct-deliver" value="false"/>
</http-acceptor>
<in-vm-acceptor name="in-vm" server-id="0"/>
<jms-queue name="ExpiryQueue" entries="java:/jms/queue/ExpiryQueue"/>
<jms-queue name="DLQ" entries="java:/jms/queue/DLQ"/>
<jms-queue name="testImport" entries="java:jboss/exported/jms/queue/testImport"/>
<connection-factory name="InVmConnectionFactory"
entries="java:/ConnectionFactory" connectors="in-vm"/>
<connection-factory name="RemoteConnectionFactory"
entries="java:jboss/exported/jms/RemoteConnectionFactory"
connectors="http-connector"/>
<pooled-connection-factory name="activemq-ra" transaction="xa"
entries="java:/JmsXA java:jboss/DefaultJMSConnectionFactory"
connectors="in-vm"/>
</server>
</subsystem>
The most important things here are the definition of testImport queue and the definition of RemoteConnectionFactory.
Because we use a remote JMS we must have remoting-connector defined in remoting subsystem:
<subsystem xmlns="urn:jboss:domain:remoting:3.0">
<endpoint/>
<http-connector name="http-remoting-connector" connector-ref="default"
security-realm="ApplicationRealm"/>
<connector name="remoting-connector" socket-binding="remoting"
security-realm="ApplicationRealm"/>
</subsystem>
And this socket binding must be also found on socket-binding-group where the remote port is specified , 4447:
<socket-binding-group name="standard-sockets" default-interface="public"
port-offset="${jboss.socket.binding.port-offset:0}">
<socket-binding name="management-http" interface="management"
port="${jboss.management.http.port:9990}"/>
<socket-binding name="management-https" interface="management"
port="${jboss.management.https.port:9993}"/>
<socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
<socket-binding name="http" port="${jboss.http.port:8080}"/>
<socket-binding name="https" port="${jboss.https.port:8443}"/>
<socket-binding name="remoting" interface="public" port="4447"/>
<socket-binding name="iiop" interface="unsecure" port="3528"/>
<socket-binding name="iiop-ssl" interface="unsecure" port="3529"/>
<socket-binding name="txn-recovery-environment" port="4712"/>
<socket-binding name="txn-status-manager" port="4713"/>
<outbound-socket-binding name="mail-smtp">
<remote-destination host="localhost" port="25"/>
</outbound-socket-binding>
</socket-binding-group>
3. Create jms context xml file (jms-import-context.xml). This is in general added in web.xml context classpath:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean name="jmsImportConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:jboss/exported/jms/RemoteConnectionFactory"/>
<property name="expectedType" value="javax.jms.ConnectionFactory"/>
</bean>
<bean id="jmsImportConnectionFactoryProxy" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
<property name="targetConnectionFactory" ref="jmsImportConnectionFactory" />
<property name="username" value="test" />
<property name="password" value="test@1975" />
</bean>
<bean id="jmsImportTransactionManager" class="org.springframework.jms.connection.JmsTransactionManager">
<property name="connectionFactory" ref="jmsImportConnectionFactoryProxy"/>
</bean>
<bean name="jmsImportDestination" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:jboss/exported/jms/queue/testImport"/>
</bean>
<bean id="jmsImportMessageListener" class="eterra.xinterface.jms.ImportJmsMessageListener">
<property name="dispatcher" ref="dataImportProcessDispatcher"/>
<property name="userDao" ref="userDao"/>
</bean>
<bean id="jmsImportMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="concurrentConsumers" value="1"/>
<property name="connectionFactory" ref="jmsImportConnectionFactoryProxy"/>
<property name="transactionManager" ref="jmsImportTransactionManager"/>
<property name="destination" ref="jmsImportDestination"/>
<property name="messageListener" ref="jmsImportMessageListener"/>
</bean>
</beans>
Here it can be seen the usage of remote connection factory url: java:jboss/exported/jms/RemoteConnectionFactory , the usage of Wildfly user/credentials, the name of the remote destination : java:jboss/exported/jms/queue/testImport. The class ImportJmsMessageListener will accept JMS BytesMessage request.
4. Configure jboss-service.xml to contain testImport queue
<?xml version="1.0" encoding="UTF-8"?><server>
<mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=testImport">
<depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
</mbean>
</server>
5. Create ImportJmsMessageListener class. Besides file content we can send in the message some useful properties like FILE_NAME and FILE_TYPE:
public class ImportJmsMessageListener implements MessageListener, InitializingBean {
@Override public void onMessage(Message message) {
LOG.info("Read message file from JMS ...");
byte[] bytes = readBytesFromJMSMessage(message);
LOG.info("Message bytes read: " + bytes.length);
// do what you need
}
/** * Reads the body of a JMS {@link Message} as a byte[].
* @param msg JMS {@link Message}
* @return the byte[] read.
* @throws JMSException if an error occurs while trying to read the body content.
*/
public byte[] readBytesFromJMSMessage(final Message msg) throws JMSException {
if (!(msg instanceof BytesMessage)) {
throw new JMSException("Message is not a BytesMessage!");
}
BytesMessage bsMsg=(BytesMessage)msg;
fileName = bsMsg.getStringProperty(FILE_NAME);
if (fileName == null) {
throw new JMSException(FILE_NAME + " property not specified!");
}
fileType = bsMsg.getStringProperty(FILE_TYPE);
if (fileType == null) {
throw new JMSException(FILE_TYPE + " property not specified!");
}
if (bsMsg.getBodyLength() >= Integer.MAX_VALUE) {
throw new JMSException("Message body is too large[" + bsMsg.getBodyLength() + "].");
}
byte[] ba=new byte[(int)bsMsg.getBodyLength()];
bsMsg.readBytes(ba);
return ba;
}
}
6. Create a test class. The most important thing here is how the remote connection factory url and queue url are used, without jboss/exported prefix used to define them in xml server configuration files. To run test class as a standalone you have to add in classpath jboss-client.jar from wildfly/bin/client folder:
public class JmsImportTest {
private String FILE_NAME = "myfile.xml";
private String FILE_PATH = "C:\\Projects";
private String FILE_TYPE = "MY_TYPE";
private String initialContextFactory = "org.jboss.naming.remote.client.InitialContextFactory";
private String serverUrl = "remote://localhost:4447";
private String userName = "test";
private String password = "test@1975";
private String remoteConnectionfactoryUrl = "jms/RemoteConnectionFactory";
private static String importQueueUrl = "jms/queue/testImport";
public void sendMessage(String queueName) {
Connection connection = null;
Session session = null;
MessageProducer msgProducer = null;
try {
System.out.println("Running " + JmsImportTest.class.toString() + " on current path " + new File(".").getAbsolutePath());
System.out.println("Publishing " + FILE_NAME + " to destination '" + queueName + "'\n");
final Properties initialContextProperties = new Properties();
initialContextProperties.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
initialContextProperties.put(Context.PROVIDER_URL, serverUrl);
initialContextProperties.put(Context.SECURITY_PRINCIPAL, userName);
initialContextProperties.put(Context.SECURITY_CREDENTIALS, password);
final InitialContext ic = new InitialContext(initialContextProperties);
ConnectionFactory factory = (ConnectionFactory)ic.lookup(remoteConnectionfactoryUrl);
final Queue queue = (Queue) ic.lookup(queueName);
connection = factory.createConnection(userName, password);
session = connection.createSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);
msgProducer = session.createProducer(queue);
BytesMessage msg = session.createBytesMessage();
msg.setStringProperty("FILE_NAME", FILE_NAME);
msg.setStringProperty("FILE_TYPE", FILE_TYPE);
Path fileLocation = Paths.get(FILE_PATH + File.separator + FILE_NAME);
byte[] data = Files.readAllBytes(fileLocation);
msg.writeBytes(data);
msgProducer.send(msg);
System.out.println("Bytes file message was published to server.");
} catch (Exception e) {
e.printStackTrace();
} finally {
if (connection != null) {
try {
connection.close();
} catch (JMSException e) {
e.printStackTrace();
}
}
}
}
public static void main(String[] args) throws JMSException {
new JmsImportTest().sendMessage(importQueueUrl);
}
}
