图书馆没有在游戏服务器端加载

Question

我有一个包含此文件的简单库：

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);
        }

}

这是用gwt运行的。我在服务器和客户端中调用此函数。它在开发模式下完美运行。当我将它上传到gae时，它只适用于客户端。

错误日志说org.jboss.resteasy.spi.UnhandledException：java.lang.NoClassDefFoundError：com / mt / utilities / shared / DateUtils

有什么建议吗？

Answer 1

确保将DateUtils代码上传到GAE。 您可能拥有War Server Project和Client Projet。 您只需使用GWT编译的文件将War Server Projet部署到服务器上吗？

最好是拥有一个包含在两个项目中的共享项目。
