Thanks for this. But is there a way to get a specific entity using the

using JDO/JPA, and there are folks who go straight to the Low-Level API.
I spoke with one internal team who mentioned an interest in Objectify but
were concerned it could be abandoned because they had had a similar

Yes, there is. Code extracts from what I use are below. I trust that

transaction. Yet I often find that during the course of a transaction

- this trains users in insecure behaviors. Instead, look into a solution
like OAuth:

I agree with Rajkumar,
GAE/J is a very important service, especially for indie Java

The service is getting better, and the developer groups are vibrant.
Happy Birthday GAE!
