Java EE (Java Enterprise Edition) General Discussion

I am trying to send mail using JAVAMAIL API with GMAIL SMTP on port 465.
Now, I setup my outlook smtp.gmail.com with port 465 and I was able to send e-mail using outlook. So, I am sure it can be done using javamail as well. However, when I tried the same with javamail, I keep getting the following authentication error: Coud someone please let mne know how to get rid of this error and make my code work?I appreciate your help.

Thanks,
Venkat

Following is the snippet of my code:

Properties p = new Properties();
p.put("mail.smtp.user", "vkat007@gmail.com");
p.put("mail.smtp.host", mailhost);
p.put("mail.smtp.port", "465");
p.put("mail.smtp.starttls.enable","true");
p.put( "mail.smtp.auth ", "true ");
p.put("mail.smtp.debug", "true");
p.put("mail.smtp.socketFactory.port", "465");
p.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
p.put("mail.smtp.socketFactory.fallback", "false");


SecurityManager security = System.getSecurityManager();
System.out.println("Security Manager" + security);


try {
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(p, auth);
session.setDebug(true);

//session = Session.getDefaultInstance(p);
MimeMessage msg = new MimeMessage(session);
msg.setText(text);
msg.setSubject(subject);
Address fromAddr = new InternetAddress("vkat007@gmail.com");
msg.setFrom(fromAddr);
Address toAddr = new InternetAddress(_to);
msg.addRecipient(Message.RecipientType.TO, toAddr);
System.out.println("Message: " + msg.getContent());
Transport.send(msg);
}
catch (Exception mex) { // Prints all nested (chained) exceptions as well
System.out.println("I am here??? ");
mex.printStackTrace();
}
}

private class SMTPAuthenticator extends javax.mail.Authenticator {

public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("vkat007@gmail.com", "xxxxxxxxxxx"); // password not displayed here, but gave the right password in my actual code.
}
}
