无法编译生成的JSP Java文件

我正在使用Neatbeans将简单项目部署到GAE，我设法部署了“空白”项目，但现在我添加了一个类，出现错误。无法编译生成的JSP Java文件

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

我得到以下错误：

这是我的项目的结构，我不知道如果放置GoogleMemcache类，那么这是正确的。

清洁，并建立从NetBeans中工作得很好。

这是index.jsp代码：

<%@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>

我已经尝试了不同的答案，我发现类似的问题，没有任何运气。

最后，我试图部署错误的文件夹中：

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

应该是：

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

我意识到那是因为它缺少一个META-INF文件夹，以便它不匹配this answer

而不是使用scriplet标记为对象的声明X

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

使用声明标签

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