I would love to get the GAE sample working from the new 2.5 release but there is something wrong I can't seem to troubleshoot.
Importing the project to Eclipse seemed to go well. I added some datanucleus jars to the path (3.0), copied all of the smartgwtee jars to war/WEB-INF/lib, and added the Appe Engine SDK (1.5.2). Those steps seemed to solve all of Eclipe's complaints about the project.
When I launch the project it appears to compile alright and when I load the client in Firefox it looks like it should, except that the Country table is stuck "Loading data..." and I get this:
Clicking the "Add some data" button yields this complaint:
This same behavior occurs both locally and when I deploy the project to GAE
And here's the Console view that goes with launching the application and opening it in the browser:
Any ideas?
