AuthenticationFailedException while sending email using Java

Question

I'm trying to send email using java API and i'm giving the right emailid and password but still i get AuthenticationFailedException.

I also tried giving host=mail.smtp.port and changing port to 587 still i end up getting the same error..

Please help me where i'm going wrong..?

public class SendEmail
   {
   public static void main(String [] args)
   {    
  // Recipient's email ID needs to be mentioned.
  String to = "[email protected]";

  // Sender's email ID needs to be mentioned
  final String from = "[email protected]";

  // Assuming you are sending email from localhost
  final String host = "smtp.googlemail.com";

  // Get system properties
  Properties properties = System.getProperties();

  // Setup mail server
  properties.setProperty("mail.smtp.host", host);
  properties.setProperty("mail.smtp.starttls.enable", "true");
  properties.setProperty("mail.smtp.user", from);
  //properties.setProperty("mail.smtp.password", "xyz");

  properties.setProperty("mail.debug", "false");
  properties.setProperty("mail.smtp.auth", "true"); 
//  properties.setProperty("mail.smtp.port", "587");

  // Get the default Session object.
 // Session session = Session.getDefaultInstance(properties);

  Session session = Session.getInstance(properties,
          new javax.mail.Authenticator() {

              protected PasswordAuthentication getPasswordAuthentication() {
                  return new PasswordAuthentication(from, "xyz");
              }
          });

  session.setDebug(true);

  try{
     // Create a default MimeMessage object.
     MimeMessage message = new MimeMessage(session);

     // Set From: header field of the header.
     message.setFrom(new InternetAddress(from));

     // Set To: header field of the header.
     message.addRecipient(Message.RecipientType.TO,
                              new InternetAddress(to));

     // Set Subject: header field
     message.setSubject("This is the Subject Line!");

     // Now set the actual message
     message.setText("This is actual message");

     // Send message
    // Transport.send(message);


     Transport.send(message);
     System.out.println("Sent message successfully....");
  }catch (MessagingException mex) {
     mex.printStackTrace();
  }
 }
}

Error:

Just check if you have enabled logging in from "Less Secure Apps" using this link. This setting needs to be enabled for the account [email protected].
