Where to keep gwt-dispatch classes?

Where gwt-dispatcher classes (Action, Result, Handler) should b开发者_C百科e kept? I mean it should be all in client package or maybe shared or any other combination? How do You handle this?

I wrote a small app called SixFixMix and in there, here's what I do:

• Action/Result classes are kept in a ...shared.rpc package
• Handler classes are kept in a ...server.handler package
