struts2.2.1配置问题

配置struts2.2.1,但是总是不成,具体情况如下:
引入的包有这些:
[img]http://dl.iteye.com/upload/attachment/566439/ce7ba3a8-ba78-3199-8533-f0b56031c838.jpg[/img]

web.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

index.jsp


struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

struts.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<constant name="struts.devMode" value="true" />

<package name="basicstruts2" extends="struts-default">

    <action name="index">
        <result>/index.jsp</result>
    </action>

</package>

启动时就显示了错误,内容:
严重: Exception starting filter struts2

根据显示,是找不到
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
但是引入包中明明存在这个,不知道为什么,求解!
