Are any of the Google's App Engine sample apps written in Java?

Question

I was looking at this repository of sample apps for Google App Engine:

http://code.google.com/p/google-app-engine-samples/

The strange thing is they all seem to be in Python.

Are there any Java sample apps for GAE?

Answer 1

There are some well documented code samples here. They accompany a book but feel useful as a stand alone, too. You can find an overview in the README_java.txt .

Update

These are sources of another book.

Answer 2

This is nice example for beginners.
