if (!errors.isEmpty()) {

}

// Save our logged-in user in the session
HttpSession session = request.getSession();
// Do something with session...

// Remove the obsolete form bean
if (mapping.getAttribute() != null) {

else

}

// Forward control to the specified success URI
return (mapping.findForward("success"));
}
}

编译时提示如下信息:
