Latest reply on Nov 17, 2016 by anky.p

I have created a class NewUserEmail.java to auto generate an email with username and password while creating a new user. I am able to create the password but whenever I am trying to log in with that password, its not logging in. I am not able to generate my mail. Please guide me and let me know what is wrong with my code:
