谷歌應用程序引擎+ JSF 2給

我使用與JSF這個linkfor谷歌應用程序引擎，所以當我在Eclipse上運行，從而給渴望解決鏈接我得到這個錯誤的錯誤是http://www.mkyong.com/google-app-engine/google-app-engine-jsf-2-example/谷歌應用程序引擎+ JSF 2給

此問題表明您沒有正確完成教程中所示的「2. JSF 2依賴項」步驟。 – BalusC

好吧我可以理解這是不夠的谷歌應用程序引擎與本教程中的jsf –

JSF 2正在使用GAE中不支持的「javax.naming.InitialContext」。

要解決這個問題：

你需要獲得JSF的源代碼的副本。複製WebConfiguration.java
評論中的方法是使用「javax.naming.InitialContext中的」類
別急，我已經修改了最新的（JSF 2.2.12），在這裏，它是：WebConfiguration.java
把它放在包com.sun.faces.config。

現在，您新創建的WebConfiguration.java類將重載原始WebConfiguration.java。

嗯我不太明白在哪裏把這個文件。我必須將JSF jar添加到我的項目中。那麼在哪？或者我把它放在我的項目源代碼中，並在我自己的項目中創建一個包「com.sun.face.config」？請幫助並解釋 – MobileMon

不，只需製作一個新包：javax.naming.InitialContext。然後是一個新的類：WebConfiguration。然後將上述文件中的課程內容複製並粘貼到新課程中。 – Yster
