I'm trying to email assistance JavaMail APIbut always makes a mistake:

AuthenticationException

Log and password Gmail You're right.

Do you need to build? Gmail SMTPand if so, how do you do it?

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 session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(username, password);
    }
});

try {

    Message message = new MimeMessage(session);
    message.setFrom(new InternetAddress(username));
    message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("mymail@gmail.com"));
    message.setSubject("Testing Subject");
    message.setText("Dear Mail Crawler," + "\n\n No spam to my email, please!");

    Transport.send(message);

    System.out.println("Done");

} catch (MessagingException e) {
    LOGGER.error(e.getLocalizedMessage());
}
