Hi guys,
Last night I launched my pet project to public, www.neytap.com. It's a
(very) simple classifieds for room rentals inside Facebook.
It runs on GAE/Java and written in Scala, using just Servlet/JSP in
the server. I tried Spring but given up.
Other than that, it uses:
Objectify, StringTemp
I was using Spring, Spring Security, Sitemesh, JSP and Objectify.
Sometimes I experienced deadline exception (remember last time request
timeout was set to 30sec).
Now that I use JSP, Servlet, Objectify and custom Sitemesh, it takes
less than 5secs to warmup.

Sorry for the stupid question, but in what scenarios would we need to
allocate id?
Usually if I need the id to be something, i just use string (e.g.
email address), otherwise, just let datastore set it for me (when
persisting).

The GAE SDK uses java.util.concurrent classes internally so I guess
they do work. However, I've never used them because when I need
locking, it should be application-wide. With java.util.concurrent you
can only achieve locking within an instance. Or am I wrong here?

Datastore allows multi-value property. So you can have each (x,y,
