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

public class SendMailTLS {

	public static void main(String[] args) {
		String host = "smtp.gmail.com";
		int port = 587;
		String username = "[e-mail]";
		String password = "password";

		Properties props = new Properties();
		props.put("mail.smtp.auth", "true");
		props.put("mail.smtp.starttls.enable", "true");

		Session session = Session.getInstance(props);

		try {

			Message message = new MimeMessage(session);
			message.setFrom(new InternetAddress("[e-mail]"));
			message.setRecipients(Message.RecipientType.TO,
				InternetAddress.parse("[e-mail]"));
			message.setSubject("Testing Subject");
			message.setText("Dear Mail Crawler," +
					"\n\n No spam to my email, please!");

			Transport transport = session.getTransport("smtp");
                        
			transport.connect(host,port,username,password);

			Transport.send(message);

			System.out.println("Done");

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

this code throws runtime exception though i am providing the correct password. Please Don't mind in this code i provide the incorrect password

Exception in thread "main" java.lang.RuntimeException: javax.mail.AuthenticationFailedException: failed to connect, no password specified?
at SendMailTLS.main(SendMailTLS.java:42)
Caused by: javax.mail.AuthenticationFailedException: failed to connect, no password specified?

Nevermind that. See the link anyway.

See this.

In NetBeans6.9 project the class path for both has been set

[masijade]

And it obviously has nothing to do with the classpath (I never said, or even hinted that it did) or you would be getting a ClassNotFoundException, of course.

See that link.

You need to read Authenticator paragraph for your reference and here you missed mail.smtp.host:host entry.

class MyAuth extends Authenticator
{
     protected PasswordAuthentication getPasswordAuthentication()
      {
         return new PasswordAuthentication("username","password"); 
      } 
}

public static void main(String[] args) {
		......
                ......
		Properties props = new Properties();
                props.put("mail.smtp.host", host);

		......
                Authenticator auth = new MyAuth();
                Session session = Session.getInstance(props, auth);
                .....

Hope it helps.
