Struts中使用html标签库为什么一直出错？

只想测试一下html标签库的所以只用到一个欢迎页面，代码如下：
<%@ taglib prefix="html" uri="/WEB-INF/struts-html.tld" %>
<%@ page language="java" contentType="text/html; charset=gb2312"
    pageEncoding="gb2312"%>
<html>
<head>
<title>ABC</title>
</head>
<body>
<h1>大标题</h1>
<hr />
<img class="d" src="http://www.cainiao8.com/images/logo.gif"/>
<form>
  <input  name="OO" type="text"/>
  <html:submit >ha ha</html:submit>
</form>
</body>
</html>
web.xml配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>

 <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
     
    
     <welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
    
    <taglib>
        <taglib-uri>/WEB-INF/struts-html.tld</taglib-uri>
        <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
    </taglib>
</web-app>
报错如下：

解决方案 »

  1.   

    导入这几个包：
    commons-fileupload-1.2.1.jar
    commons-io-1.3.2.jar
    commons-logging-1.0.4.jar
    freeer-2.3.16.jar
    javassist-3.7.ga.jar
    ognl-3.0.jar
    struts2-core-2.2.1.1.jar
    xwork-core-2.2.1.1.jar
      

  2.   

    加了   还是抛异常：
