and here it is my program that i got from some forum
----

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class mail3 {

/**
	 * @param args
	 */
	String d_email = "email@gmail.com",
	d_password = "password",
	d_host = "smtp.gmail.com",
	d_port = "587",
	m_to = "hanars3012@yahoo.com",
	m_subject = "last Test",
	m_text = "Hey, this is the testing email.";
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		mail3 test=new mail3();		
		System.out.println(test.send());
	}
	public String send(){
		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.ssl.enable", "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(System.out);
			return "error";
		} 
		//System.out.println("send");
		return "sent";
		
	}
	
	private class SMTPAuthenticator extends javax.mail.Authenticator
	{
			public PasswordAuthentication getPasswordAuthentication()
			{
				return new PasswordAuthentication(d_email, d_password);
			}
	}
}

I have tried to use both port 465 & 587 but still always return error...

thanks in advance,
