Do you mean examples of sites using DWR? If so, I think there's avcouple mentioned on the DWR site itself.
Is DWR a framework? No, not in and of itself. But, that depends on how you define a framework I suppose

It's not what most people would consider a framework I'd say. It's "just" a mechanism for doing remote procedure calls from Javascript to server-side
Java code.
I would argue however that with DWR, there's simply no point for a full-blown framework any more. If you allow your client to be the UI of the application, and *also* allow it to, by and large, control application flow, then a framework is superfluous IMO and DWR is all you need.
