無法編譯生成的JSP Java文件

Question

我正在使用Neatbeans將一個簡單的項目部署到GAE，我設法部署了“空”項目，但是現在我添加了一個類，但我遇到了錯誤。

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

我收到以下錯誤：

這是我的項目的結構，我不確定是否將GoogleMemcache類放置在正確的位置。

從Netbeans進行清理和構建就可以了。

這是index.jsp的代碼：

<%@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>

我已經嘗試過對類似問題發現的不同答案，但沒有任何運氣。

Answer 1

而不是使用scriplet標記來聲明對象x

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

使用聲明性標簽

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

Answer 2

最后，我嘗試部署錯誤的文件夾：

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

本來應該：

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

我意識到這是錯誤的，因為它缺少META-INF文件夾，因此與該答案中所述的文件夾不匹配
