Question

在我的GWT客户端，我从服务器端请求LightEntities列表。我对实体进行了一些修改，然后尝试将它们发送回来进行保存。

当我进行rpc调用时，它失败并出现以下异常：

[WARN] Exception while dispatching incoming RPC call

我现在坐在这个错误上几个小时了，那就是LazyKiller杀了我，任何提示我应该再看一眼了吗？

Answer 1

我无法解决这个问题，但我做了一些解决方法：我在客户端克隆了我的实体，然后我可以将它们发送回服务器端。

Answer 2

我试图使用吉利德，但这很糟糕：

它是如此具有侵略性;
配置起来很难。

我编写了一个将hibernate代理转换为普通java类的小类，这对我很有帮助。它在那里作为开源共享，所以你可以尝试：

尝试发送LightEntity抛出线时GWT GiLead Hibernate IllegalArgumentException
