Il est difficile de dire ce qui ne va pas avec une pile complète, mais je parierais sur un mauvais constructeur "FROM" donc "InetAddress" –

Je ne sais pas ce que vous essayez d'accomplir, mais ce scriptlet est exécuté AVANT le l'utilisateur obtient la page, non quand il soumet ce formulaire –

Évitez autant que possible l'utilisation de scriptlets. http://stackoverflow.com/questions/3177733/how-to-avoid-java-code-in-jsp-files?rq=1 –

Votre JSP sera exécuté pour afficher la forme, et il essayera d'envoyer un e-mail avant que l'utilisateur ait une chance d'entrer quoi que ce soit.

Vous feriez mieux de déplacer le code java dans une servlet.

Ou déplacez la pièce d'envoi vers une page JSP différente qui est la cible du POST lorsque le formulaire est soumis. –

Je pense que si vous faites cela dans Servlet c'est mieux.

Regardez là, je vais vous donner un exemple de base, il obtiendra les paramètres de formulaire HTML et travailler dans servlet comme:

`@WebServlet("/Servlet") 
    public class Servlet extends HttpServlet { 
    private static final long serialVersionUID = 1L; 

    /** 
    * @see HttpServlet#HttpServlet() 
    */ 
    public Servlet() { 
     super(); 
     // TODO Auto-generated constructor stub 
    } 

    /** 
    * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse 
    *  response) 
    */ 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException { 
     PrintWriter out = response.getWriter(); 
     response.setContentType("text/html"); 
     RequestDispatcher requestDispatcher; 

     String from = request.getParameter("sender"); 
     String password = request.getParameter("pass"); 
     String to = request.getParameter("receiver"); 
     String subject = request.getParameter("subject"); 
     String message = request.getParameter("message"); 

     Properties properties = System.getProperties(); 
     properties.put("mail.smtp.auth", "true"); 
     properties.put("mail.smtp.starttls.enable", "true"); 
     properties.put("mail.smtp.port", "587"); 

     if (from.contains("hotmail")) { 
      properties.put("mail.smtp.host", "smtp.live.com"); 

     } else if (from.contains("gmail")) { 
      properties.put("mail.smtp.host", "smtp.gmail.com"); 

     } else if (from.contains("yahoo")) { 
      properties.put("mail.smtp.host", "smtp.mail.yahoo.com"); 

     } else { 
      out.println("<h2 style='color:red;'>Unknown domain name!!</h2><br>" 
        + "<p>Please use 'Yahoo or Gmail or Hotmail'</p>"); 
     } 

     Session messageSession = Session.getDefaultInstance(properties, new Authenticator() { 
      @Override 
      protected PasswordAuthentication getPasswordAuthentication() { 

       return new PasswordAuthentication(from, password); 
      } 
     }); 

     try { 
      MimeMessage mimeMessage = new MimeMessage(messageSession); 
      mimeMessage.setFrom(new InternetAddress(from)); 
      mimeMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to)); 
      mimeMessage.setSubject(subject); 
      mimeMessage.setText(message); 

      Transport.send(mimeMessage); 
      requestDispatcher = request.getRequestDispatcher("index.html"); 
      requestDispatcher.forward(request, response); 
      out.println("<h2 style='color:green;'>Message sended successfully.</h2><br>" + "<p>Welldone.</p>"); 

     } catch (MessagingException e) { 
      requestDispatcher = request.getRequestDispatcher("index.html"); 
      out.println("<h2 style='color:red;'>Fatal Error!!</h2><br>" + "<p>" + e.getMessage() + "</p>"); 
     } 

    } 

} 
`

et formulaire HTML de base:

<body> 
<h1 align="center">Send Email Form</h1> 
<form class="cf" action="Servlet" method="post"> 
    <div align="center"> 
     <table> 
      <tr> 
       <td>From : </td><td><input type="email" name="sender" size="30px" class="input-email" 
        placeholder="Email address"></td> 
      </tr> 
      <tr> 
       <td>Password : </td><td><input type="password" name="pass" size="30px" class="input-email" 
        placeholder="Sender Password"></td> 
      </tr> 
      <tr> 
       <td>To : </td><td><input type="email" name="receiver" size="30px" class="input-email" 
        placeholder="Email address"></td> 
      </tr> 
      <tr> 
       <td>Subject : </td><td><input type="text" name="subject" size="30px" class="input-email" 
        placeholder="Subject"></td> 
      </tr> 
      <tr> 
       <td>Message : </td><td><textarea name="message" id="input-message" 
         class="text" placeholder="Message"></textarea></td> 
      </tr> 
      <tr> 
       <td><input type="submit" value="SEND" class="button"> 
       </td> 
       <td><input type="reset" value="CLEAR" class="button"> 
       </td> 
      </tr> 
     </table> 
    </div> 

</form>

J'espère que cela vous aidera.
