JavaMail - java.net.ConnectException: Connection timed out: connect

This is my code. And though it should be simple enough to send a mail, but I have been encountering the error mentioned below. And I have tried searching everywhere, but with no results. Thanks in advance !

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

public class SendMailBySite {  
 public static void main(String[] args) {  

 String to="[email protected]";//change accordingly  

  //Get the session object  
  Properties props = new Properties();  
  props.put("mail.smtp.host", "smtp.gmail.com");  
  props.put("mail.smtp.socketFactory.port", "465");  
  props.put("mail.smtp.socketFactory.class",  
            "javax.net.ssl.SSLSocketFactory");  
  props.put("mail.smtp.auth", "true");  
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.port", "465");  

  Session session = Session.getDefaultInstance(props,  
   new javax.mail.Authenticator() {  
   protected PasswordAuthentication getPasswordAuthentication() {  
   return new PasswordAuthentication("[email protected]","********");//change accordingly  
   }  
  });  

  //compose message  
  try {  
   MimeMessage message = new MimeMessage(session);  
   message.setFrom(new InternetAddress("[email protected]"));//change accordingly  
   message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));  
   message.setSubject("Hello");  
   message.setText("Testing.......");  

   //send message  
   Transport.send(message);  

   System.out.println("message sent successfully");  

  } catch (MessagingException e) {throw new RuntimeException(e);}  

 }  
}

This is the error encountered :
