<!DOCTYPE struts PUBLIC

    <action name="hello" class="Action.HelloAction">
        <result name = "success">/index.jsp</result>
        </action>
    </package>
</struts>


action类

 **package action;

public class HelloAction {
    public String execute(){
        System.out.println("hello struts2");
        return "success";
    }
}

错误提示:
ERROR org.apache.struts2.dispatcher.Dispatcher - Dispatcher initialization failed
java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

后面还有一些列错误,包括 无法初始化filter什么的一系列,问题描述看起来特别像jar包没有正确导入,但是我从官网上下的,原封不动的导入进入lib,为了怕官方jar包错误,我还特意把空项目war解压下来在lib中找到ar包导入,可是还是出问题,用的服务器是tomcat,特来求解

头都大了,查了好多资料,都不是我遇到的情况,求大大们看一下,才开始学习struts不久,用的myeclipse blue edition,头疼。。。
