庫在GAE服務器端

不加載我有一個包含該文件的簡單庫：庫在GAE服務器端

import java.util.Date; 

public class DateUtils { 
     public static Date addDays(Date date, int days) { 
      assert date != null : "Date cannont be null"; 
       return new Date(date.getYear(), date.getMonth(), date.getDate() + days); 
     } 

}

這與GWT運行。我在服務器和客戶端調用這個函數。它在開發模式下完美工作。當我將它上傳到gae時，它只能在客戶端工作。

錯誤日誌說org.jboss.resteasy.spi.UnhandledException：java.lang.NoClassDefFoundError：COM /噸/公共事業/共享/ DateUtils

有什麼建議？

您使用的是Maven嗎？螞蟻？蝕？問題可能出現在您的項目設置中。 –

謝謝Gilberto，我使用Maven並剛添加了我的pom.xml文件。我使用Eclipse上傳到gae – user1256378

確保您的DateUtils代碼已上傳到GAE。你可能有War Server Project和一個Client Projet。而你只是將War Server Projet部署到GWT編譯文件的服務器上？

最好的是有一個共同的項目誰被包括在這兩個項目。

感謝Partice，我只是添加了我的pom.xml並使用Eclipse中的gwt插件上傳。當我看着我的目標/ WEB-INF/lib目錄時，庫就在那裏。它在gae的客戶端工作正常，而不是服務器端，在開發模式下，它在服務器端和客戶端都能正常工作。 – user1256378

庫在GAE服務器端
