I really like the fast, schema-less datastore, and i would like to
have that on my model objects.
So, instead of using POJOs for Model/TO, i am using HashMaps.
I have extended HashMap adding key and parent properties to have a one-
to-one mapping with Entity.
Using this approach, i gain:

Java is a strongly typed language for good reason - it makes it harder
to make mistakes. You should only use extension if your data model
is a HashMap - probably never. For example, a Product data model is
not a HashMap.
You are describing building a type-safe wrapper to the datastore.

Hey all,
I'm using Spring 3 with full annotations for my controllers and can
not figure out how to get rid of my context root other than using
urlrewrite. The problem with urlrewrite is that I still need to
maintain an xml document so I can find my controller and methods
with their request path.
Ya, you can delete all the entries through your app engine account. After
logging in check the entries in the datastore, Select all and delete.

I intended to put bytes of article.jsp output as a property on Article

But I guess I will run into similar situation one day again,
Thank you for the reply.
I'm seeing InheritanceStrategy.SUBCLASS_TABLE for the very first

properly.
I will get back to this approach soon, so I will definitely let you
know whether it helped or not.
Thanks again, regards

This code:

don't have permission to set on App Engine. Instead use
setInstanceFollowRedirects, which you can set per http connection.

Ok,
Unfortunately I confirmed the same error you're getting:

Oh, as to my claim of being able to put 2GB into the datastore...
yeah, when I looked at the test it was a unit test and not an
integration test, so the datastore was mocked and it just checked the
correct put call sequence. Sorry for getting excited over nothing :)

Encryption might be the right solution for your application, but it
does carry some significant limitations on your ability to use app

I think it is important to consider the data you are dealing with
