sending email with ssl using javax.mail

From reading this: http://www.oracle.com/technetwork/java/javamail/faq-135477.html#commonmistakes

The use of

props.put("mail.smtp.socketFactory.class",
        "javax.net.ssl.SSLSocketFactory");** 

and

props.put("mail.smtp.socketFactory.port", "465");

is kind of outdated. To simplify the code, use:

properties.put("mail.smtp.port", "465");
properties.put("mail.smtp.ssl.enable", "true");

Instead of

props.put("mail.transport.protocol", "smtps");

Transport transport = session.getTransport("smtps");

Use

props.put("mail.transport.protocol", "smtp");

Transport transport =session.getTransport("smtp");

Use smtp, not smtps

I used JDK 8, Netbeans 8, JavaMail 1.5.2 and this example works fine:

public static void main(String[] args) {
    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() {
                            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("[email protected]","password");
            }
        });

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[email protected]"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("[email protected]"));
        message.setSubject("Testing Subject");
        message.setText("Test Mail");

        Transport.send(message);

        System.out.println("Done");

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

If you are not able connect with port 465, try port 587

If you using Windows and have any Antivirus or firewall disable it and try.
