我正在使用 Neatbeans 将一个简单的项目部署到 GAE，我设法部署了“空”项目，但现在我添加了一个类，但出现错误。

当我运行时：appcfg update C:\Users\lsarni\Documents\NetBeansProjects\TestMemcache\web

我收到以下错误：

这是我项目的结构，我不确定将类 GoogleMemcache 放在那里是否正确。

在此处输入图像描述

从 Netbeans 清理和构建工作得很好。

这是中的代码index.jsp：

<%@page import ="Memcache.GoogleMemcache" %>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <%
        GoogleMemcache x = new GoogleMemcache();
        %>
    </body>
</html>

我已经尝试了对类似问题找到的不同答案，但没有任何运气。

而不是使用 scriplet 标记来声明对象 x

<%  GoogleMemcache x = new GoogleMemcache(); %>

使用声明性标签 

<%!  GoogleMemcache x = new GoogleMemcache(); %>

最后我试图部署错误的文件夹：

appcfg update C:\Users\lsarni\Documents\NetBeansProjects\TestMemcache\web

本来应该：

appcfg update C:\Users\lsarni\Documents\NetBeansProjects\TestMemcache\build\web

我意识到那是错误的，因为它缺少一个文件夹，因此与此答案META-INF中描述的不匹配
