message driven bean avec jboss 6 - ejb-3.0

Question

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="clientId", propertyValue="mdbtopic-test"),
#ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
#ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/MailConfirmationMdbTopic")
})
public class MailConfirmationMdbBean implements MessageListener {
private static final Logger log = Logger.getLogger(MailConfirmationMdbBean.class);
public MailConfirmationMdbBean(){

// Pour la classe de test MailConfirmationProducteur
if (message instanceof TextMessage) {
TextMessage mail = (TextMessage) message;
// L'envoi d'un mail de confirmation au client est ici simul� par l'affichage d'un message au niveau des logs.
try {

and for testting i have this tow programe :
public class MailConfirmationConsommateur implements MessageListener {

} catch (JMSException e) {
e.printStackTrace();
}
}
}
#PreDestroy
public void remove() {

}
}
and
public class MailConfirmationProducteur {

}
i don't now if i am on the good way or no

msg.setText("Mail de confirmation pour le client.");
producteur.send(msg);
producteur.close();
log.info("Message envoyé.");
}
}

Answer 1

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.");
}
my message driven bean :

#PreDestroy
public void remove() {

}
}
for the producer and consumer programe , you can test with this :
package com.soutem.ejb.mdb;
import java.io.FileInputStream;
import java.util.Properties;
import javax.annotation.PreDestroy;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageListener;
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");
// 2: cr�ation d'une connection JMS
Connection conn = factory.createConnection();
// 3: cr�ation d'une session
Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
// 4. Recherche d'une destination
Topic topic = (Topic) ctx.lookup("topic/MailConfirmationMdbTopic");
// 5: cr�ation d'un consommateur de message
MessageConsumer consommateur = session.createConsumer(topic);
consommateur.setMessageListener(this);
System.out.println("Client JMS MailConfirmationConsommateur à l'écoute de messages.");
conn.start(); //
}
public void onMessage(Message msg) {
if (msg instanceof TextMessage) {
TextMessage tm = (TextMessage) msg;
// L'envoi d'un mail de confirmation au client est ici simul�
// par l'affichage d'un message au niveau des logs.
try {
String mail = tm.getText();
System.out.println("Le client JMS MailConfirmationConsommateur a reçu le message : " + mail);
} catch (JMSException e) {
e.printStackTrace();
}
}
}
#PreDestroy
public void remove() {
System.out.println("Suppression du client JMS MailConfirmationConsommateur.");
}
}
package com.soutem.ejb.mdb;
import java.io.FileInputStream;
import java.util.Properties;
import javax.annotation.Resource;
import javax.jms.*;
import javax.naming.InitialContext;
import org.jboss.logging.Logger;
public class MailConfirmationProducteur {
private static final Logger log = Logger.getLogger(MailConfirmationProducteur.class);
public static void main(String[] args) 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");
// 2: cr�ation d'une connection JMS
Connection conn = factory.createConnection();
// 3: cr�ation d'une session
Session session = conn.createSession(false,Session.AUTO_ACKNOWLEDGE);
// 4: Recherche d'une destination
Topic topic = (Topic) ctx.lookup("topic/MailConfirmationMdbTopic");
// 5: cr�ation d'un producteur de message
MessageProducer producteur = session.createProducer(topic);
// 6: publication d'un message
TextMessage msg = session.createTextMessage();
msg.setText("Mail de confirmation pour le client.");
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
