Answer 1

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");
                }
    });
