Thank you lp, and Didier. Actually this application will need to run in production, and not only in testing.
I need to be able to update the application's datastore with a feed from Analytics. When I create a very simple GUI for it using GWT (basically just a submit button,) I get a timeout exception because the Analytics server takes too long to respond (it seems to be unsolvable at this point.) So I thought I'll just run it as a simple Java application -- and than I don't have the timeout problem and the Analytics feed works beautifully. But then -- this problem. When I create objects from the Analytics feed, and try to insert them into the datastore, I get the exception above. What am I missing? You help is greatly appreciated!
