struts 的saveErrors问题: cannot resolve symbol: method saveErrors (javax.servlet.http.HttpSer

在struts1.1中是否没有saveErrors?
  在action中提示:
  cannot resolve symbol: method saveErrors (javax.servlet.http.HttpServletRequest,org.apache.struts.action.ActionMessages)in class strutsdemo.ValidatorAction at line 14 (14:13)   
  如何解决?
------解决方法--------------------------------------------------------
有，你的错误在于你saveErrors（参数1，参数2）参数2的类型不对！
------解决方法--------------------------------------------------------
errors.add(ActionMessages.GLOBAL_MESSAGE,new ActionMessage("error.update.invalid"));
  saveErrors(request,errors);
