Hi i want to notify my client when a critical operation is happened , so i want to use the message driven bean
i ve writen this mdb `

@MessageDriven(mappedName = "topic/MailConfirmationMdbTopic", 
activationConfig = {
 //@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
 //@ActivationConfigProperty(propertyName="subscriptionDurability", propertyValue="Durable"),
 //@ActivationConfigProperty(propertyName="subscriptionName", propertyValue="topicmdb"),

 @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
 @ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/MailConfirmationMdbTopic")  
})

public class MailConfirmationMdbBean implements MessageListener {

and for testting i have this tow programe :

public class MailConfirmationConsommateur implements MessageListener {
 public static void main(String[] args) throws Exception {
     new MailConfirmationConsommateur();
 }

 public MailConfirmationConsommateur() throws Exception {

       try {
        String mail = tm.getText();
        System.out.println("Le client JMS MailConfirmationConsommateur a reçu le message : " + mail);
       } catch (JMSException e) {

       }
      }
 }

 @PreDestroy 
 public void remove() {
     System.out.println("Suppression du client JMS MailConfirmationConsommateur.");
 }

}

and

 public class MailConfirmationProducteur {

     private static final Logger log = Logger.getLogger(MailConfirmationProducteur.class);

     public static void main(String[] args) throws Exception { 
         // Properties proprietes = new Properties();

          producteur.send(msg);

          producteur.close(); 
          log.info("Message envoyé.");
     }
    }

i don’t now if i am on the good way or no
on the console i have this error

it works now , i fill the solution : here 

the  methode on my session bean for producing mail :

    public void producteurMail(Commande commande) {
        // Properties proprietes = new Properties();
        // proprietes.load(new FileInputStream("jndi.properties")
        InitialContext ctx = null;
        try {
            ctx = new InitialContext();
        } catch (NamingException e) {
            e.printStackTrace();
        }
        // 1: recherche d'une connection factory
        ConnectionFactory factory = null;
        try {
            factory = (ConnectionFactory) ctx.lookup("ConnectionFactory");
        } catch (NamingException e) {
            e.printStackTrace();
        }
        // 2: création d'une connection JMS
        Connection conn = null;
        try {
            conn = factory.createConnection();
        } catch (JMSException e) {
            e.printStackTrace();
        }
        // 3: création d'une session
        Session session = null;
        try {
            session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
        } catch (JMSException e) {
            e.printStackTrace();
        }
        // 4: Recherche d'une destination
        Topic topic = null;
        try {
            topic = (Topic) ctx.lookup("topic/MailConfirmationMdbTopic");

        } catch (NamingException e) {
            e.printStackTrace();
        }
        // 5: cr�ation d'un producteur de message
        MessageProducer producteur = null;
        try {
            producteur = session.createProducer(topic);
        // 6: publication d'un message
        TextMessage msg = null;

            msg = session.createTextMessage();
            msg.setText("Votre Commande est en cour de traitment .");
            //producteur.
            producteur.send(msg);
            producteur.close();
            conn.close();
            session.close();
        } catch (JMSException e) {
            e.printStackTrace();
        }
        log.info("Message envoyé.");
    }

         public void remove() {
             log.info("Suppression de MailConfirmationMdbBean.");
         }
    }  

for the producer and consumer programe , you can test with this :




     package com.soutem.ejb.mdb;

    import javax.jms.Session;
    import javax.jms.TextMessage;
    import javax.jms.Topic;
    import javax.naming.Context;
    import javax.naming.InitialContext;

    public class MailConfirmationConsommateur implements MessageListener {

         public static void main(String[] args) throws Exception {
             new MailConfirmationConsommateur();
         }
     public MailConfirmationConsommateur() throws Exception {

          Properties proprietes = new Properties();  
          proprietes.load(new FileInputStream("jndi.properties")); 
          InitialContext ctx = new InitialContext(proprietes);

          // 1:  recherche d'une connection factory
          ConnectionFactory factory = (ConnectionFactory) ctx.lookup("ConnectionFactory");

          producteur.send(msg);

          producteur.close(); 
          log.info("Message envoy�.");
     }
    }

you need also some configuration on the server to set up the topic so you need to add this lines on the /server/default/deploy/hornetq/hornetq-jms.xml

    <topic name="/topic/MailConfirmationMdbTopic">
        <entry name="/topic/MailConfirmationMdbTopic"/>
    </topic>
you need also to configure the java mail by adding your smtp privider , mail and pass  here is the config 

    <mbean code="org.jboss.mail.MailService"
         name="jboss:service=Mail">
    <attribute name="JNDIName">java:/Mail</attribute>
    <attribute name="User">.......@gmail.com</attribute>
    <attribute name="Password">.........</attribute>
    <attribute name="Configuration">
      <!-- A test configuration -->
     <configuration>
    <property name="mail.smtp.host" value="smtp.gmail.com">
    <property name="mail.smtp.port" value="465">
    <property name="mail.smtp.auth" value="true">
    <property name="mail.smtp.ssl.enable" value="true">
   </property></property></property></property></configuration>
    </attribute>
    <depends>jboss:service=Naming</depends>
  </mbean>

So hope it can be helpful any question i can give a hand
