 public static void sendMail(Properties properties, final String fromEmail, final String password, String toEmail,
   String subject, String msg) {

  try {
   Session session = Session.getInstance(properties, new javax.mail.Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
     return new PasswordAuthentication(fromEmail, password);
    }
   });

   Message message = new MimeMessage(session);
   message.setFrom(new InternetAddress(fromEmail));
   message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toEmail));
   message.setSubject(subject);
