hai friends,

i wrote one standalone program to send a mail using gmail smtp server.
The program is

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class Main
{
String d_email = "username@gmail.com",
d_password = "****",
d_host = "smtp.gmail.com",
d_port = "465",
m_to = "tomailaddress",
m_subject = "Testing",
m_text = "Hey, this is the testing email.";

public Main()
{
Properties props = new Properties();
props.put("mail.smtp.user", d_email);
props.put("mail.smtp.host", d_host);
props.put("mail.smtp.port", d_port);
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");
//props.put("mail.smtp.debug", "true");
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

//SecurityManager security = System.getSecurityManager();

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

MimeMessage msg = new MimeMessage(session);
msg.setText(m_text);
msg.setSubject(m_subject);
msg.setFrom(new InternetAddress(d_email));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
Transport.send(msg);
}
catch (Exception mex)
{
mex.printStackTrace();
}
}

public static void main(String[] args)
{
Main blah = new Main();
}

private class SMTPAuthenticator extends javax.mail.Authenticator
{
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(d_email, d_password);
}
}
}

Here one exception is raised.

That exception is

javax.mail.SendFailedException: Sending failed;
nested exception is:
class javax.mail.MessagingException: Could not connect to SMTP host: smt
p.gmail.com, port: 465;
nested exception is:
java.io.IOException: Couldn't connect using "javax.net.ssl.SSLSocketFact
ory" socket factory to host, port: smtp.gmail.com, 465; Exception: java.lang.ref
lect.InvocationTargetException
at javax.mail.Transport.send0(Transport.java:218)
at javax.mail.Transport.send(Transport.java:80)
at Main.<init>(Main.java:41)
at Main.main(Main.java:51)



can any one tell me what is the problem.
thanks in advance
nani
