Bhim, did you write anything? Didier, I tried it but it doesn't work. I think that at this point I have three more things to try:
1. Deploy a Java app and set up a cron job to start it, and hope something good happens. 2. Run the demo app at http://code.google.com/p/ga-api-java-samples/source/browse/trunk/src/v1/appengine-sample/#appengine-sample/src/sample/logic . It seems to be doing exactly what I'm doing but maybe I'm missing something. 3. This one is actually a question: can I get to the application's datastore from outside of App Engine? If I can write to from another technology altogether my application can work. But I assume that this would require using some remote technology, a Web Service maybe, and it seems like an overkill for an application that using a traditional database and hosting service is conceptually very simple. I'm going to post this to the Analytics group as well, and if none of the above solutions work I'll have to ditch App Engine. It's unfortunate because the technology is super-cool but if I can't get it to work, I can't get it to work.
