Google Web Toolkit（GWT）+ Google App Engine（GAE）+分离数据持久性 [英] Google Web Toolkit (GWT) + Google App Engine (GAE) + Detached Data Persistence

问题描述

我想开发一个需要使用GWT和GAE的数据持久性的web应用程序。据我所知，我唯一的（或至少是最方便的）数据持久性选项是GAE的数据存储，使用JDO或JPA注释对象。我还希望能够使用GWT远程过程调用（RPC）来发送客户端 - 服务器对象，因此我的对象必须能够分离。但是，GWT RPC序列化不能处理分离的JDO / JPA对象，并且它不会像在不久的将来那样出现。

我的问题：最简单的最直接的解决办法呢？能够与服务器端持久性共享相同对象客户端/服务器将非常方便。

编辑

我应该澄清一点，我仍然希望将GWT RPC与GAE的数据存储一起使用。我只是寻找能够让所有这些技术一起工作的最佳解决方案。 尝试使用 http://gilead.sourceforge.net/

I would like to develop a web-app requiring data persistence using GWT and GAE. As I understand it, my only (or at least by far the most convenient) option for data persistence is GAE's Datastore, using JDO or JPA annotated objects. I would also like to be able to send my objects back and forth client-server using GWT Remote Procedure Calls (RPC), therefore my objects must be able to "detach". However, GWT RPC serialization cannot handle detached JDO/JPA objects and it doesn't appear as though it will in the near future.

My question: what is the simplest and most direct solution to this? Being able to share the same objects client/server with server-side persistence would be extremely convenient.

EDIT

I should clarify that I still wish to use GWT RPC with GAE's Datastore. I am just looking for the best solution that would allow all these technologies to work together.
