源自：2-2 Struts2 案例代码实现

请大家都帮忙解答一下，百度了好久也没改出来

我的Strust文件源代码：

<?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">


<struts>


    <package name="default" namespace="/" extends="struts-default">


        <action name="helloworld" class="com.imooc.action.HelloWorldAction">

            <result >/result.jsp </result>

        </action>

    </package>



</struts>


报的错误为：

Caused by: Action class [com.imooc.action.HelloWorldAction] not found - action - file:/E:/na/mystrust/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/HelloWorld/WEB-INF/classes/struts.xml:10:77

    package com.imooc.action;

    import com.opensymphony.xwork2.ActionSupport;

    public class HelloWorldAction {//不用继承
     
    public String execute()  {
    System.out.println("hjk");
    return "success";

    }
    }

    <action name="helloworld" class="com.imooc.action.HelloWorldAction">

        <result name="success">//这个地方需要你com.imooc.action.HelloWorldAction返回一个execute（）的字符串

        /result.jsp

        </result>

        </action>

    class没找到，就是com.imooc.action.HelloWorldAction没找到，输出 class="com.imooc.action.HelloWorldAction"内容是Alt+/让他自动提示看看是不是这个
