無法編譯生成的JSP Java文件

我正在使用Neatbeans將簡單項目部署到GAE，我設法部署了「空白」項目，但現在我添加了一個類，出現錯誤。無法編譯生成的JSP Java文件

當我運行：appcfg update C:\Users\lsarni\Documents\NetBeansProjects\TestMemcache\web

我得到以下錯誤：

這是我的項目的結構，我不知道如果放置GoogleMemcache類，那麼這是正確的。

清潔，並建立從NetBeans中工作得很好。

這是index.jsp代碼：

<%@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>

我已經嘗試了不同的答案，我發現類似的問題，沒有任何運氣。

最後，我試圖部署錯誤的文件夾中：

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

應該是：

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

我意識到那是因爲它缺少一個META-INF文件夾，以便它不匹配this answer

而不是使用scriplet標記爲對象的聲明X

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

使用聲明標籤

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

描述的我改變了，但錯誤仍然存在錯了 – moondaisy
