    pass = context.getInitParameter("pass");
  }
 
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
  {
    response.setContentType("text/html;charset=UTF-8");
    PrintWriter out = response.getWriter();
StringBuilder builder = new StringBuilder("<html><body>");
 
      builder.append("<br><br><u>Nom:</u>").append(nom).append("<br><br> <u>Entreprise:</u>").append(entreprise).append("<br><br><u>Email:</u> ").append(email).append("<br><br><u>Téléphone:</u> ").append(tel).append("<br><br><u>Site web:</u> ").append(site).append(" <br><br><u>Message:</u> ").append(message);

      } catch (MessagingException e) {
         throw new RuntimeException(e);

   }
}

Je vais l'exploiter.

C'est bon, ça marche.
