Muhannad, I agree with Litty and Gregor. Probably the best thing to bring clarity to you at this point would be for you to develop the canonical GWT single-page rich client application and use a single GWT RPC Service for all data needs. Get comfortable with that model (you can do a lot with it!) before you try to hybridize with standard page-load- page web application style. In particular, drop the idea of Service- per-URL. Yagni.
