Google Engine App - InitialContext 是一个受限类

Question

我正在使用带有 Google Engine 应用程序的 Eclipse 来公开我的服务器，但我遇到了错误：

 
java.lang.NoClassDefFoundError: javax.naming.InitialContext is a restricted class. Please see the Google  App Engine developer's guide for more details.

我找到了这个解决方案：

http://www.mkyong.com/google-app-engine/gae-jsf-javax-naming-initialcontext-is-a-restricted-class/

我做到了，我在自己的项目中添加了 WebConfiguration.java 但我仍然面临这个问题，也许我的课程不是项目在访问 WebConfiguration 时正在阅读的课程，也许它正在阅读“旧的和错误的”文件包含 2 个无法读取的方法，因为这会产生错误。

有人可以帮帮我吗？

非常感谢:)

您应该将 WebConfiguration.java 放在正确的包 (com.sun.faces.config) 中。 根据您发布的stacktrace，仍然调用了不兼容的方法processJndiEntries，因此没有使用您的类。
