Are they expecting working prototypes? Is there any period for developing it and then submitting ?

The official Java tutorial is also worth taking a look at. It's free, updated and more concise compared to most books.

Ok. But why restrict only to code.google.com? why not track other project hosts as well?

If you just want to target code.google.com, they already offer Atom feeds of project issues.

At my last job we used NLTK, Stanford NER and POS tagger, and some components from Lucene.
