I have a GWT app which contains, besides traditional “client” and “server” packages, also a “shared” package, which contains POJO DTOs that travel back/forth through RPC. I need to create some methods in those DTOs which should exist only on server-side (i.e. they should not be compiled to JS, because they’d use code which is not compile-able to JS), especially the static() method.
Is this possible in GWT (some attribute, ifdef, …)?
Background:
I have some generic validators which require “registration” of the class to be validated (via a static method register(Class<T>), and since I can’t find any GWT init() method I’d put the registration in static constructors of the DTOs, so when (if) the class gets loaded it registers itself for validation.
