javamail isSSL false even though I've set tls to True when sending mail

I'm trying to use javamail to send out an email. It worked in a java application. But i got some errors when i use it in my Weblogic web application.

Properties props = new Properties();
props.setProperty("mail.transport.protocol", "SMTPS");
props.setProperty("mail.smtp.host", "msg.petrochina.com.cn");
props.setProperty("mail.smtp.port", "465");
props.setProperty("mail.smtp.auth", "true");
MailSSLSocketFactory sf = null;
try {
  sf = new MailSSLSocketFactory();
  sf.setTrustAllHosts(true);
} catch (GeneralSecurityException e1) {
  e1.printStackTrace();
}
props.put("mail.smtp.ssl.enable", "true");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.fallback", "false");
props.put("mail.smtp.ssl.socketFactory", sf);
final Authenticator authenticator = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication("[email protected]", "123456");
}
};

Session session = Session.getDefaultInstance(props, authenticator);
session.setDebug(true);
MimeMessage mimeMessage = new MimeMessage(session);
  mimeMessage.setFrom(new InternetAddress("[email protected]","dqlhgys"));
  mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
  mimeMessage.setSubject("test");
  mimeMessage.setSentDate(new Date());
  mimeMessage.setText("testMailContent","utf-8");
  mimeMessage.saveChanges();
  Transport.send(mimeMessage);

When i run the app I can see the following in my log

DEBUG: set            
DEBUG: JavaMail version 1.4.1

    javax.mail.MessagingException: 454 tls initialize failed: ssl accept error. (#4.7.0) (eYou MTA)

It seems the application is trying to connect without ssl, and it won't connect.But i can connect the address with telnet.telnet

First, fix all these common JavaMail mistakes.

Then, remove the mail.transport.protocol setting. ("SMTPS" is the wrong protocol name, it should be "smtps", but I believe it's being ignored because of the above problems, and you don't want it because of the properties you're setting.)

Depending on your mail server, you should need either mail.smtp.ssl.enable to use SSL when first connecting to the server, or you should need mail.smtp.starttls.enable to connect usingplain text and then switch to SSL/TLS after connecting. You should never need both.

Hopefully that will fix your problem.

But note that you're using a very old version of JavaMail, which must mean you're using a very old version of WebLogic. If possible, upgrade to a newer version of WebLogic.
