struts问题－访问jsp页面出现：Cannot find ActionMappings or ActionFormBeans collection

仔细检查了一下，不知错在哪里
我的web.xml:

解决方案 »

  1.   

    你的jsp文件action中是不是写错了,注意大小写
      

  2.   

    logon.jsp文件内容：
    <%@ taglib uri="/tags/struts-html" prefix="html" %>
    <%@ page contentType="text/html; charset=gb2312" %> 
    <% 
    /** 
    * This page shows Logon interface. 
    * Title: LOGON SYSTEM 
    * Description: Logon Page 
    * Copyright: Copyright (c) 2004 
    * Company: www.ewe.com.cn 
    * @author bluesunny <[email protected]> 
    * @version 1.0 
    */ 
    response.setHeader("Pragma","No-cache"); 
    response.setHeader("Cache-Control","no-cache"); 
    response.setDateHeader("Expires", 0); 
    %> 
    <html> 
    <head> 
    <title>Logon</title> 
    </head> 
    <body> 
    <html:errors/> 
    <html:form action="/Logon" focus="username"> 
    username:<html:text property="username" size="25"/> 
    password:<html:password property="password" size="25"/> 
    <html:submit property="submit"/> 
    </html:form>  </body> 
    </html>
      

  3.   

    补充说一下，我是打开logon.jsp的时候就报的错
      

  4.   

    表示path的属性值前面加上/试试，再就是注意大小写的问题
      

  5.   

    <html:form action="/Logon.do" focus="username">如此改
      

  6.   

    看花了眼，配置文件弄错了。
    <action-mappings>没有封闭
