当我在我的项目中在WEB-INF中添加faces-config.xml文件时，我很奇怪它会导致错误“RES_NOT_FOUND”
注意：我试过<link type="text/css" rel="stylesheet" href="style.css" />
没有faces-config.xml，它工作正常。我也尝试将其移到 resources 文件夹
我尝试使用此代码为我的.xhtml页面添加css文件
<h:head>
<h:outputStylesheet name="styles.css" />
</h:head>
它将生成以下
<link type="text/css" rel="stylesheet" href="RES_NOT_FOUND">
我正在使用JSF 2.2 + Google App Engine，因为我遵循本网站的教程
除了我尝试导入.css，.js和图像文件之类的外部文件之外，该教程很顺利;当我直接从像localhost：8080 / style.css这样的链接访问它时，css文件将正确显示。
这是我的代码

任何人都可以指出我的项目的哪个部分导致错误。我真的想使用faces-config.xml而不会出错。我的重点是，我无法导入我的项目中存在faces-config.xml的css，js和其他文件。是否有任何我为JSF和GAE设置错过的配置或信息。
