Answer 1

I'm assuming you are using spring security. After successful login put the UserDetails object in the session like so (This is usually the controller where you would forward if login was successfull)

Object principal = SecurityContextHolder.getContext()
     .getAuthentication().getPrincipal();
HttpSession session = request.getSession(true); //create a new session

// put the UserDetails object here.
session.setAttribute("userDetails", principal);

In your JSP you can access the UserDetails object, like so:

Welcome ${userDetails.username}
