public class TutorialAction {

    public String execute(){
        System.out.println("Hello from execute");
        return "failure" ;
    }
}

我创建了success.jsp，error.jsp＆amp; index.jsp文件也是如此。我正在使用eclipse-indigo＆amp; Apache tomcat 7.0.62。当我在Tomcat服务器上运行项目时，它在控制台上显示此错误消息并显示HTTP状态404 - / Struts2Starter描述所请求的资源不可用。名为Apache Tomcat的新选项卡上的错误消息。

Answer 1

将.jar文件复制到 WebContent / WEB-INF / lib 文件夹中，根据struts库教程提供的部署程序集定义在部署应用程序时可能无法正常工作。它对我有用。

错误：无法加载配置。 - action，引起：在eclipse上运行Strache 2时，没有找到Action类
