Build register & login web using servlet and jspa Website

The system is very simple. Registration means entering in a form an email, full name and password, After successful registration, the user is presented with the login page, If a user closes the browser and reopen the login page (if the Java session still exists) You should build a user login page. A JSP login page will check the login against the DB (login is the email, and password) and after successful login it will display a welcome page with all currently logged in users, and a logout button. The logout will close the user session and return to the login page.
