I think so it is asking for authentication of your username.

session=Session.getInstance(props,
         new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(fromUsername, password);
            }
          });

And then use above session in your code.

I haven't use the code specified in the google link u mentioned but i use java mail api to send email from my gmail account.Use above code for authentication
