So far so good with Google AppEngine. I was at first afraid that I would have to create separate model objects on both the client and server side as the GWT compiler was complaining about model classes not being serializable (DTOs, yuck). Since my model class did in fact implement Serializable, I thought it was the JDO persistence annotations messing it up. But not to worry, I merely forgot the public empty constructor. Now GWT and JDO can use the same model class to represent an object, and life is good.
I successfully created my first prayer list using Google DataStore (AppEngine).
Now it’s time to dig deep into GWT to understand how best to wire related parts of the view together with each other, the controller, and the model…
