Google app engine 未使用struts2在Google应用程序引擎中加载索引文件

当我尝试访问我的struts2 tiles应用程序（在google app engine中）时，出现以下错误

与上下文路径[]关联的命名空间

[/]

和操作名称[]没有映射的操作[未知位置]

下面是堆栈跟踪

我不知道为什么默认情况下它不加载

index.html

请告知

问候,，

将以下空白操作添加到“/”包命名空间中的struts.xml文件中，当您仅尝试访问url（如appid.app.com）时，它将显示index.html，并且不会显示错误。通常，它将添加空白动作，App引擎将重定向空白操作到欢迎文件。

    <action name="" class="com.candi.actions.Dashboard" method="noAction">
        <result name="success">index.jsp</result>
    </action>

index.jsp

让我们进一步解释。只需通过提供blank“”作为操作名称来添加blank操作，并将结果重定向到index.php即可解决问题
