Java 无法部署到google apps引擎

我有一个小应用程序，当在本地主机上进行测试时，它运行良好

但当我想将其部署到google app engine服务器时，我有以下错误：

我认为有用的文件在这里：

您的项目是否在客户端使用GWT？当您的部署尝试执行一个特殊的GWT兼容步骤时，它失败了

我相信您的问题在于RDFServlet类是GWT模块的一部分，这不是您想要的

GAE的默认Eclipse项目预先配置为与GWT一起使用。示例中的包结构如下所示：

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

当GWT将client/down编译为JavaScript时，它需要所有依赖项的完整源代码，并且有许多类不应该被引用。但是，在客户机包中似乎有一个servlet RDFServlet

您可能希望在项目中禁用GWT，或者将RDFServlet移动到不属于GWT模块的包中。例如，如果您使用的是Eclipse示例项目，servlet将放在“服务器”包的某个地方。

您能否检查gwt.xml是否包含所有需要的模块。例如，对于使用GWT XML，您需要继承XML模块，比如：我没有使用任何GWT工具，禁用Eclipse中的GWT工具特性就可以了。谢谢
