Sending mail with username and pasword.

Question

Lets say that I wanted to write some code which can send messages via my gmail account. How could I tell my session that what my username and password are?

Answer 1

Can't get this code to work. Can't get past the Transport.send(msg) part but it doesnt throw an exception instead it just blocks indefinitely.
package mailtest;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class Main
    public static void main(String[] args) throws Throwable
        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "465");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.user", "[email protected]");
        props.put("mail.smtp.password", "*********");
        Session s = Session.getDefaultInstance(props, new javax.mail.Authenticator()
            public PasswordAuthentication getPasswordAuthentication()
                return new PasswordAuthentication("[email protected]", "*********"); // password not displayed here, but gave the right password in my actual code.
        MimeMessage msg = new MimeMessage(s);
        msg.setFrom(new InternetAddress("[email protected]"));
        msg.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
        msg.setSubject("NONE");
        msg.setText("Hello!");
        Transport.send(msg);
        System.out.println("SENT");
}
