Programme java pour envoi de mail

Bonjour,


J'ai un programme pour l'envoi de Mail qui ne fonctionne pas. il ne me donne pas d'erreurs mais il n'envoi pas les messages. voilà le code :

classe SendMail:

package pack1;

import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.Message.RecipientType;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SendMail {

private String from;
private String to;
private String subject;
private String text;

public SendMail(String from, String to, String subject, String text){
this.from = from;
this.to = to;
this.subject = subject;
this.text = text;
}

public void send(){

Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");

Session mailSession = Session.getDefaultInstance(props);
Message simpleMessage = new MimeMessage(mailSession);

InternetAddress fromAddress = null;
InternetAddress toAddress = null;
try {
fromAddress = new InternetAddress(from);
toAddress = new InternetAddress(to);
} catch (AddressException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
}

try {
simpleMessage.setFrom(fromAddress);
simpleMessage.setRecipient(RecipientType.TO, toAddress);
simpleMessage.setSubject(subject);
simpleMessage.setText(text);

Transport.send(simpleMessage);
} catch (MessagingException e) {
// TODO Auto-generated catch block
// e.printStackTrace();
}
}
}

Classe Main :


package pack1;

public class Test {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
SendMail s1=new SendMail("groupeisi2013@gmail.com", "elkadiri.wd@gmail.com", "Test send mail", "Avez vous reçu mon mail?? By Abdelouhab elkadiri");
s1.send();
}

}
