有错？
LogIn.jsp 页面：
<html:form action="/Login.do" method="post">
struts-config.xml文件：
<action-mappings >
<action
attribute="logInForm"
name="logInForm"
path="/Login"
scope="request"
type="LogInAction"
validate="true"
input="/error.jsp"
/>
打开 http://127.0.0.1:8080/Struts_Demo/LogIn.jsp 出现如下错误
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

这是为什么 是不是和前两个文件的这些部分有关？ login的大小写也都试过了，没有用哦
其他文件还有
fail.jsp, error.jsp, success.jsp, LogInActionForm.java, LogInAction.java
