mise en œuvre du service de messagerie dans mon code

Question

J'ai essayé d'implémenter le code de servlet suivant pour implémenter le service de messagerie, mais je reçois constamment des erreurs avec ce code. pls un coup d'oeil ...

import java.io.IOException; 
import java.io.PrintWriter; 
import java.util.Properties; 
import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import java.util.Properties; 
import javax.mail.*; 
import javax.mail.internet.*; 
import javax.servlet.RequestDispatcher; 

public class email extends HttpServlet { 

protected void processRequest(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 
    String to="amanmaheshwari25@gmail.com"; //emailID at which the mail is send 

    response.setContentType("text/html;charset=UTF-8"); 
    PrintWriter out = response.getWriter(); 
    Session session=null; 

    try{ 
     Properties props = new Properties(); 
     props.put("mail.smtp.host", "smtp.gmail.com"); 
     props.put("mail.smtp.socketFactory.port", "465"); 
     props.put("mail.smtp.socketFactory.class", 
        "javax.net.ssl.SSLSocketFactory"); 
     props.put("mail.smtp.auth", "true"); 
     props.put("mail.smtp.port", "465"); 

     session = Session.getDefaultInstance(props, 
     new javax.mail.Authenticator() { 
     protected PasswordAuthentication getPasswordAuthentication() { 
     return new PasswordAuthentication("cconatus.2011@gmail.com","password");//change accordingly 
     } 
     });} 
     catch(Exception e) 
     {out.println("error234");} 
     try { 
     MimeMessage message = new MimeMessage(session); 
     message.setFrom(new InternetAddress("ccnatus.2011@gmail.com"));//change accordingly 
     message.addRecipient(Message.RecipientType.TO,new InternetAddress(to)); 
     message.setSubject("Pls find the message inside"); 
     String dd = "hey"; 
     message.setText(dd); 

     //send message 
     Transport.send(message); 
     out.println("success"); 
      } 
     catch(Exception e) 
      {out.println("error");} 
     finally {    
       out.close(); 
      } 
     } 

la sortie que je reçois est: i.e. d'erreur du dernier bloc catch pls donner quelques suggestions concernant ce dès que possible.

Voici les propriétés qui ont travaillé pour moi:

mail.transport.protocol = smtp

mail.smtp.host = smtp.gmail.com

mail.smtp.auth = true

mail.smtp.starttls.enable = true

mail.smtp.port = 587
