Not that tough to deal with. Change the code to:
HttpSession session = request.getSession(true);
UserInfoBean uib = (UserInfoBean) session.getValue("theUserInfoBean");
if (uib == null)
session.putValue("theUserInfoBean", uib);
uib.setUserName(request.getParameter("userName");
uib.setUserpassword(request.getParameter("userpassword");
