How Struts is Used! Created Forms (model) Created Forms (model) AddArticleForm, LoginForm, etc AddArticleForm, LoginForm, etc Wrote classes to process forms Wrote classes to process forms edu.union.struts.LoginForm.java: // Get Username & Password from form String username = (String)(newLoginForm.get("username")); String password = (String)(newLoginForm.get("password")); // Check to make sure they’re in the database & passwords are correct Staff authUser = (Staff)smanager.getBySignInCredentials(username, password); //On Login Success return (mapping.findForward("success")); Hibernate Call
