Hello World示例中的ZKoss Framework错误404

Question

我按照ZKoss Framwork中的步骤创建了Hello World示例。 基本上，当你尝试创建一个新的ZK项目时，据说你不需要改变任何东西就能运行Hello World屏幕。

  

    

Hello World Tutorial

  

但是，我一直收到以下错误： HTTP状态404 - / ZKTest /

你可以帮我解决这个问题吗？

这是[index.zul]：

<?page title="Auto Generated index.zul"?>
<window title="Hello World!!" border="normal" width="200px">

<label value="You are using: ${desktop.webApp.version}"/>

</window>

这是[web.xml]：
