What I do is something like this:
// assuming we are creating a new session for login
HttpSession session = request.getSession(true);
FormBean formBean = new FormBean();
formBean.setUserName(
request.getParameter("userName"));
formBean.setPassword(request.getParameter("password"));
if ( formBean.validate()) {
session.setAttribute("formBean", formBean);
URL = "Welcome";
} else {
URL = "Index";
}
