Struts2框架配置问题

[bascker]

最近学习Java Web开发，学到Struts2框架部分。我就按照教程提供的一个最简单的案例试了下。
可是总是出现问题。都3天了，还没找到具体解决方法。只能想个大神求救了。
我使用的是MyEclipse，Tomcat的版本是7.0.27
其web.xml中的配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
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">
<display-name></display-name>

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

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


<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

在src目录下的Action代码为：
package com.johnnie.action;

import com.opensymphony.xwork2.ActionSupport;

public class HelloAction extends ActionSupport{
private static final long serialVersionUID = 1L;

@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
System.out.println("Hello,This is my first Struts App");
return SUCCESS;
}

}

与Action同一目录下的struts.xml文件配置：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<package name="default" namespace="/" extends="struts-default">
<action name="hello" class="com.johnnie.action.HelloAction" method="execute">
<result name="SUCCESS">/index.jsp</result>
</action>
</package>

这些我都按照教程配置好了，jar包是最新版的struts-2.3.15.3的。但是就是报错，Console控制台错误信息如下：
log4j:WARN No appenders could be found for logger (com.opensymphony.xwork2.util.fs.DefaultFileManagerFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

一直找不到解决办法，小弟对此真是没办法了。跪求各大神指点迷津

struts.xml要放在SRC根目录下

[cqslideng]

Caused by: org.xml.sax.SAXParseException: Document root element "package", must match DOCTYPE root "struts". 修改：

<struts>
<package name="default" namespace="/" extends="struts-default">
<action name="hello" class="com.johnnie.action.HelloAction" method="execute">
<result name="SUCCESS">/index.jsp</result>
</action>
</package>
</struts>

我晕了，还真是忘了写<struts>了，我哭死。谢谢大神的解惑
