struts2的问题（头疼）
昨天想部署个struts2的helloworld工程，一直不行，各位大牛帮小弟看看，多谢
名为HelloWorld.java的action：
package test;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorld extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
public String message;
/**
* @param message the message to set
*/
public void setMessage(String message) {
this.message = message;
}
/**
* @return the message
*/
public String getMessage() {
return message;
}
@Override
public String execute(){
message = "Hello World!!!";
return SUCCESS;
}
}
名为result.jsp显示helloworld的jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@taglib uri= "/struts-tags" prefix ="s"%>

<action name="HelloWorld" class="test.HelloWorld">
<result>result.jsp</result>
</action>
</package>
</struts>
在浏览器里输入http://localhost:8080/Test/HelloWorld.action
或者http://localhost:8080/Test/result.jsp
最后画面结果总是
HTTP Status 404 -
--------------------------------------------
type Status report
message
description The requested resource () is not available.
--------------------------------------------
Apache Tomcat/5.5.31
啥问题啊，想不出来，各位大牛帮帮小弟吧，谢谢
------解决方案--------------------
启动的时候控制台有没有报错？如果启动报错，那么不管你访问什么都是404。
