Question

The method getParameter(String) is undefined for the type HttpServletRequest，怎么回事啊！

String strUserName = request.getParameter("txtUserName");
String strPassWord = request.getParameter("txtPassWord");
getParameter下面画有红线，当鼠标放在上面是出现The method getParameter(String) is undefined for the type HttpServletRequest，这是怎么回事啊，求高手解决！

可能是你当前包中的有的类名和 ‘HttpServletRequest’ 的类名相同了，仔细检查一下吧。
