無法部署到谷歌應用程序引擎

Question

我有一個小應用程序，它在本地主機上測試時工作正常。

但是，當我要部署到Google App Engine的服務器，我有放入系統錯誤：

Compiling module org.magnetik.semola.Org_magnetik 
    Validating newly compiled units 
     Ignored 1 unit with compilation errors in first pass. 
Compile with -strict or with -logLevel set to TRACE or DEBUG to see all errors.

     [ERROR] Hint: Previous compiler errors may have made this type unavailable 
     [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly

請問您的項目中使用GWT的客戶端？當您嘗試執行特殊的GWT合成步驟時，您的部署失敗。

我相信你的問題是你的RDFServlet類是GWT模塊的一部分，這不是你想要的。

GAE的默認Eclipse項目預先配置爲與GWT一起使用。該軟件包是結構的例子是這樣的：

client/ <--- GWT code (for client side, compiled to JavaScript) 
shared/ <--- Code necessary on both the client and server 
server/ <--- Server side code 

當GWT編譯的客戶端/下降到JavaScript的，它需要所有依賴的全部源代碼，並有一些不應該被引用的許多類。但是，您似乎在「客戶端」軟件包中有一個servlet（RDFServlet）。

您可能想要在您的項目中禁用GWT，或將RDFServlet移動到不屬於GWT模塊的程序包中。 （例如，如果您使用的是Eclipse示例項目，則Servlets將放在「服務器」包的某個位置。
