Question

I’m using GWT 2.5, and RPC to exchange information between client and server.

I’m trying to define the interface that extends RemoteService and another one CRUDService<T> that has among others (CRUD methods) the following method:

public Class<T> getDtoType();

But this method is only intended to be user by the implementation, on the server side.

Is there a way not to expose this method to client side (transient method)?

Otherwise I’m getting an error, when I compile the project, saying Class<T> does not implements Serializable nor IsSerializable.

Could anyone help me?

Answer 1

Not possible. Atleast not without hacking gwt-dev and rpc related code for service proxy generation.

1) SampleService extends RemoteService, CrudService<String>
2) SampleService extends CrudService<String> ( where CrudService extends RemoteService )

In both above scenarios Async Interface cribs first. If you fix it then GWT proxy generators crib about Serialization interface.
