Failed to compile the generated JSP java files

Question

I'm using Neatbeans to deploy a simple project to GAE, I managed to deploy the "empty" project but now that I added a class I'm getting an error.

When I run: appcfg update C:\Users\lsarni\Documents\NetBeansProjects\TestMemcache\web

I get the following error:

This is the structure of my project, I'm not sure if placing the class GoogleMemcache there is the right thing to do.

Clean and build from Netbeans work just fine.

This is the code in 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>

I have tried the different answers I found to similar questions without any luck.

Instead of using scriplet tag for declaration of Object x

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

use declarative tag

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

In the end I was trying to deploy the wrong folder:

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

Should have been:

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

I realized that was the wrong one because it was missing a META-INF folder so it didn't match the one described in this answer
