What's the minimum number of interfaces and classes that I should need to create for a new RpcService?

Currently, I am looking at creating 2 interfaces and 3 classes for every RpcService. I'm wondering if I can do better before I start implementing a ton of services.

• Interface to extend RemoteService
• Interface for AsyncCallback
• Class to represent the request and hold its DTO
• Class to represent the response and hold its DTO
• Class to implement my Interface above that extends RemoteService.

I've been looking at trying to do better here wvia DI. But so far I haven't really hit on the right solution. I did get Guice to manage my servlets via ServletModule and GuiceServletContextListener though.

I need to implement about 40 services in the shortest time possible and I don't want to create more boilerplate than I need. I already have all of the DTOs (auto generated) and I just need to hook them up to new services.

If anyone can identify the part of this that can be improved, I can provide some sample code to help identify the solution easier.

Thank you,
