Thank you for your answer!

To build up a frontend to use complex business services (Spring based
application with service and business layer on top of it) would you
recomend GWT RPC instead of RequestFactory?

It's not a secret that I very much prefer RequestFactory over any form of RPC, mostly because RequestFactory forces you to think about your messages and your protocol, and it doesn't tie your client(s) to a specific version of your server code (requiring that you update everyone at the same time –ok, that's not entirely true, but that's how (too) many people do it–).

That said, I don't use onConstraintViolations, and I think it was a mistake to build bean validation into RequestFactory.

RequestFactory has many limitations that can make it hard to use in an application. Once those limitations will be removed (next year maybe; in GWT 3.0; depends if/when I have time to do it), it'll be much better and become as usable as GWT-RPC.

So I won't tell you "use this" or "use that". I think RequestFactory is better than GWT-RPC despite its current limitations, but you'll likely run into them as they're not prominently documented, so it might be better for you to use GWT-RPC, despites its limitations.
