Javamail using Gmail SMTP 465 port!

Question

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

Hi!
I tried the following code:
String mailhost = "smtp.gmail.com";
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", mailhost);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.quitwait", "false");
Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username", "password");
MimeMessage message = new MimeMessage(session);
message.setSender(new InternetAddress(from));
message.setSubject("test");
message.setContent("hello!", "text/plain");
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
addressTo[i] = new InternetAddress(recipients);
message.setRecipients(Message.RecipientType.TO, addressTo);
Transport.send(message);
} catch (AddressException ex) {
ex.printStackTrace();
out.print(ex);
} catch (MessagingException ex) {
ex.printStackTrace();
out.print(ex);
}catch(Exception ex){
out.print(ex);
But I get following error:
javax.mail.AuthenticationFailedException: 535-5.7.1 Username and Password not accepted. Learn more at 535 5.7.1 http://mail.google.com/support/bin/answer.py?answer=14257 b12sm2275215rvn.22
Kindly let me know the code to send mails using Gmail SMTP server through JavaMail. I am using Win XP.
The JavaMail code which was working in Win 7 is:
try {          
String username=null;
String password=null;
boolean debug = true;
//Set the host smtp address
Properties props = new Properties();
//props.put("mail.smtp.host", "smtp.live.com");
String host="smtp.gmail.com";
props.put("mail.smtp.auth", "true");
//props.put("mail.smtp.port","587");
// props.put("mail.smtp.port","465");
//props.put("mail.smtp.port","995");
//props.put("mail.smtp.port","8084");
// Authenticator a1= new PopupAuthenticator();
// create some properties and get the default Session
Session session1 = Session.getDefaultInstance(props, null);
session1.setDebug(debug);
// create a message
Message msg = new MimeMessage(session1);
// set the from and to address
//InternetAddress addressFrom = new InternetAddress(from);
//msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
addressTo[i] = new InternetAddress(recipients[i]);
msg.setRecipients(Message.RecipientType.TO, addressTo);
// Setting the Subject and Content Type
msg.setSubject("test");
msg.setContent("hello!", "text/plain");
//msg.setText(message);
//Transport.send(msg);
username = from;
password = pwd;
Transport t = session1.getTransport("smtps");
try {
t.connect(host, username, password);
//t.connect(host, username);
msg.saveChanges();
t.sendMessage(msg, msg.getAllRecipients());
catch (Exception ex) {
//ex.printStackTrace();
out.println(ex);
finally {
t.close();
} catch (Exception ex) {
ex.printStackTrace();
out.println(ex);
/* Email Sent*/
Unfortunately this code does not work in Win XP. Following exception is generated in Win XP:
javax.mail.MessagingException: can't determine local email address
It wuld be great if somebody could help me out with this issue in Win XP asap.
