Your code seems to access any other server but not the gmail smtp server.

If you want to use the gmail server you need authentication for the account. The following piece of source code may help you. Note: I used javax.mail version 1.4.7

import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


public class App {

    public static void main(String[] args) {
        String from = "[email protected]";
        String to = "[email protected]";

        Properties properties = createConfiguration();

        SmtpAuthenticator authentication = new SmtpAuthenticator();

        Session session = Session.getDefaultInstance(properties, authentication);

        try {

            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress(from));
            message.addRecipient(Message.RecipientType.TO,
                new InternetAddress(to));

            message.setSubject("This is the Subject Line!");

            // Now set the actual message
            message.setText("This is actual message");

           // Send message
           Transport.send(message);

           System.out.println("Sent message successfully....");
        } catch (MessagingException mex) {
           mex.printStackTrace();
     }
 }

 private static Properties createConfiguration() {
    return new Properties() {
        {
            put("mail.smtp.auth", "true");
            put("mail.smtp.host", "smtp.gmail.com");
            put("mail.smtp.port", "587");
            put("mail.smtp.starttls.enable", "true");
        }
    };
 }

 private static class SmtpAuthenticator extends Authenticator {

        private String username = "[email protected]";
        private String password = "secret";

        @Override
        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    }
}
