This program attempts to send e-mail but throws a run time exception:

javax.mail.AuthenticationFailedException: failed to connect, no password specified?

Why am I getting this exception when I have supplied the correct username and password for authentication?

Both the sender and receiver have g-mail accounts. The sender and the receiver both have g-mail accounts. The sender has 2-step verification process disabled.

This is the code:

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

class tester {
    public static void main(String args[]) {
        Properties props = new Properties();
        props.put("mail.smtp.host" , "smtp.gmail.com");
        props.put("mail.stmp.user" , "username");

        //To use TLS
        props.put("mail.smtp.auth", "true"); 
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.password", "password");
        //To use SSL
        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.port", "465");


        Session session  = Session.getDefaultInstance( props , null);
        String to = "me@gmail.com";
        String from = "from@gmail.com";
        String subject = "Testing...";
        Message msg = new MimeMessage(session);
        try {
            msg.setFrom(new InternetAddress(from));
            msg.setRecipient(Message.RecipientType.TO, 
                new InternetAddress(to));
            msg.setSubject(subject);
            msg.setText("Working fine..!");
            Transport transport = session.getTransport("smtp");
            transport.connect("smtp.gmail.com" , 465 , "username", "password");
            transport.send(msg);
            System.out.println("fine!!");
        }
        catch(Exception exc) {
            System.out.println(exc);
        }
    }
}

Even after giving the password I get the exception. Why is it not authenticating?


Try to create an javax.mail.Authenticator Object, and send that in with the properties object to the Session object.

Authenticator edit:

You can modify this to accept a username and password and you can store them there, or where ever you want.

public class SmtpAuthenticator extends Authenticator {
public SmtpAuthenticator() {

    super();
}

@Override
public PasswordAuthentication getPasswordAuthentication() {
 String username = "user";
 String password = "password";
    if ((username != null) && (username.length() > 0) && (password != null) 
      && (password.length   () > 0)) {

        return new PasswordAuthentication(username, password);
    }

    return null;
}

In your class where you send the email:

SmtpAuthenticator authentication = new SmtpAuthenticator();
javax.mail.Message msg = new MimeMessage(Session
                    .getDefaultInstance(emailProperties, authenticator));

You need to add the Object Authentication as the Parameter to the Session. such as

Session session = Session.getDefaultInstance(props, 
    new javax.mail.Authenticator(){
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(
                "XXXX@gmail.com", "XXXXX");// Specify the Username and the PassWord
        }
});

now You will not get this kind of Exception....

Your email session should be provided an authenticator instance as below

Session session = Session.getDefaultInstance(props,
    new Authenticator() {
        protected PasswordAuthentication  getPasswordAuthentication() {
        return new PasswordAuthentication(
                    "myemail@gmail.com", "password");
                }

In addition to RMT's answer. I also had to modify the code a bit.

  1. Transport.send should be accessed statically
  2. therefor, transport.connect did not do anything for me, I only needed to set the connection info in the initial Properties object.

here is my sample send() methods. The config object is just a dumb data container.

public boolean send(String to, String from, String subject, String text) {
    return send(new String[] {to}, from, subject, text);
}

public boolean send(String[] to, String from, String subject, String text) {

    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.host", config.host);
    props.put("mail.smtp.user", config.username);
    props.put("mail.smtp.port", config.port);
    props.put("mail.smtp.password", config.password);

    Session session = Session.getInstance(props, new SmtpAuthenticator(config));

    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        InternetAddress[] addressTo = new InternetAddress[to.length];
        for (int i = 0; i < to.length; i++) {
            addressTo[i] = new InternetAddress(to[i]);
        }
        message.setRecipients(Message.RecipientType.TO, addressTo);
        message.setSubject(subject);
        message.setText(text);
        Transport.send(message);
    } catch (MessagingException e) {
        e.printStackTrace();
        return false;
    }
    return true;
}

I've solved this issue adding user and password in Transport.send call:

Transport.send(msg, "user", "password");

According to this signature of the send function in javax.mail (from version 1.5):

public static void send(Message msg, String user, String password)

Also, if you use this signature it's not necessary to set up any Authenticator, and to set user and password in the Properties (only the host is needed). So your code could be:

private void sendMail(){
  try{
      Properties prop = System.getProperties();
      prop.put("mail.smtp.host", "yourHost");
      Session session = Session.getInstance(prop);
      Message msg = #createYourMsg(session, from, to, subject, mailer, yatta yatta...)#;
      Transport.send(msg, "user", "password");
  }catch(Exception exc) {
      // Deal with it! :)
  }
}
