In GWT 2.0.x you can use the annotations of the JPA and JDO without problems and without using any additional library. Your source code will be compiled normally. No exception (SerializableException) will occur.
So what's the problem: In a relationship one-to-many, when the GWT tries to serialize this attribute that is a "List", will probably return an exception (LazyInitializationException). Return an attribute that has a relationship one-to-many is not good for various reasons, the principal is the performace. Solution Add the annotation @GwtTransient above in the attribute "List" and everything will work normally. Advantage: You use a native GWT solution to deal with this type of information. Decreases some jars in your application, and get 10 ~ 200ms each request. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
