Of course not. You can *present* datastore object in JSON (JavaScript Object Notation). Use POJO (Plain Old Java Object) concept while creating data Model of your application. You can easilly present list of Model objects in JSON, you can easilly convert them from JSON to POJO on GWT (Java, client-side). The same thing happens on server-side. Parse incomming JSON and construct Model objects (in Python) using parsed data.
GWT+GAE can work together. Ofcourse, this way won't be productive comparing to Java backend. But anyway, if you want to make good stable complicated UI, don't use JS - it's paiful. Use OO Java and be happy like I am ^) On Mar 17, 4:57 pm, Amr Ellafi <[email protected]> wrote: > Pavel, > that's a good idea, you mean you can pass objects from the datastore > to GWT via JSON ? > > On Tue, Mar 17, 2009 at 3:50 PM, Pavel Byles <[email protected]> wrote: > > > Coonay, > > I use GWT and GAE together and I think it's a pretty good setup. > > First, instead of using servlets you will use the request builder and > > pass data using JSON instead. 2nd I effectively just send my HTML > > output of my GWT project to my GAE project and configure my app.yaml > > accordingly. > > > Using this method you will lose a really big part of GWT, which is the > > debugging feature since you will be running dev_appserver.
