I am trying to design a jsp page where I can send an e-mail

  • 0

I am trying to design a jsp page where I can send an e-mail but the code which is properly running in core java is giving me exception when used in jsp code. I believe I have properly placed my mail.jar in lib.

The current jsp code is:

<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>

                <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

                <html>
                <body>

                <%@ page import="java.util.Properties" %>               
                <%@ page import="javax.mail.Message" %>
                <%@ page import="javax.mail.MessagingException" %>
                <%@ page import="javax.mail.PasswordAuthentication" %>
                <%@ page import="javax.mail.Session" %>
                <%@ page import="javax.mail.Transport" %>
                <%@ page import="javax.mail.internet.InternetAddress" %>
                <%@ page import="javax.mail.internet.MimeMessage" %>


                <%
                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.getDefaultInstance(props,
                            new javax.mail.Authenticator() {
                                protected PasswordAuthentication getPasswordAuthentication() {
                                    return new PasswordAuthentication("prakash.d2222","**************");
                                }
                            });

                        try {

                            Message message = new MimeMessage(session);
                            message.setFrom(new InternetAddress("from@no-spam.com"));
                            message.setRecipients(Message.RecipientType.TO,
                                    InternetAddress.parse("prakash_d22@rediffmail.com"));
                            message.setSubject("hi");
                            message.setText("12345" +
                                    "\n\n No spam to my email, please!");

                            Transport.send(message);

                            System.out.println("Done");

                        } catch (MessagingException e) {
                            throw new RuntimeException(e);
                        }
                %>
                </body>
                </html>

and the error that I’m seeing is:

org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 37 in the jsp file: /pizza/page/ssl.jsp
The constructor MimeMessage(HttpSession) is undefined

    Message message = new MimeMessage(session ); // error

    In JSP page session is a implicit object which is actually javax.servlet.http.HttpSession.

    I think you are confused with HttpSession and mail javax.mail.Session.Session. Change you
    code like –
    …

     Session mailSession = Session.getDefaultInstance(props,
                                new javax.mail.Authenticator() {
                                    protected PasswordAuthentication 
                                          getPasswordAuthentication() {
                                        return new PasswordAuthentication
                                          ("prakash.d2222","**************");
                                    }
                                });

    …

    Message message = new MimeMessage(mailSession );
