struts-xml文件：

<!DOCTYPE struts PUBLIC
     "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
     "http://struts.apache.org/dtds/struts-2.0.dtd">

    <package name="struts2" extends="struts-default" >
        <action name="register"  class="com.fenfen.FuctionRegisterAction">
            <result name="success">/success.jsp</result>
        </action>
    </package>
</struts>

web-xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>myNewProj</display-name>
    <!-- 定义Struts2的FilterDispathcer的Filter -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>

    <!-- FilterDispatcher用来初始化struts2并且处理所有的WEB请求。 -->
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <welcome-file-list>
        <welcome-file>/indexfirst.jsp</welcome-file>
    </welcome-file-list>
</web-app>

查了很多，原因最多是struts-xml文件放错位置，还有就是struts-xml文件配置错误。我的struts-xml文件放在了src文件夹下，应该没有放错地方，但是<?xml version="1.0" encoding="UTF-8"?>头文件报错。请大牛帮我看看配置有没有错误，O(∩_∩)O谢谢
能正确出现indexfirst.jsp页面，但是单击确定的时候报错。
