JavaMail TLS email

[Rob Proesmans]

Hello, I am searching for almost 5 hours how to send an non-authenticated/authenticated email through javamail with gmail as SMTP server.
I do not want to use SSL but I rather prefer TLS.

The problem is, that i keep having this error:

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

here is my code:

<%@page import="java.security.Security"%>
<%@ page import="java.util.*, javax.mail.*, javax.mail.internet.*" %>
<%
String host = "smtp.gmail.com";
String port = "587";
String user = "[e-mail]";
String pass = "mypassword";
String to = "[e-mail]";
String from = "[e-mail]";
String subject = "Test subject";
String messageText = "Test body";
boolean sessionDebug = false;

Properties props = System.getProperties();
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.user", user);
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", port);
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");
//props.put("mail.smtp.debug", "true");


// Uncomment these 3 lines below and comment out 2 lines above if you prefer to use SSL
// props.put("mail.smtps.auth", "true");
// props.put("mail.smtps.port", "465");
// props.put("mail.smtps.ssl.trust", host);
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(sessionDebug);

Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(messageText);
Transport transport = mailSession.getTransport("smtp");
transport.connect(host, user, pass);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
%>

i don't understand why it keeps saying this error.
please can anybody help me out? (I have the mail.jar & activation.jar in my lib)
