Gwt + AppEngine CRUD

We're going to develop a brand new software for our customer. While evaluating different technologies, the most interesting I found is Google App Engine cloud service. This will keep all the system engineering complexity management out of my mind I think. The price is more work on the code: the开发者_运维技巧 eventual consistency of the datastore, and so on.

Google Web Toolkit looks as the best companion to GAE, too. I just deployed an hello world.

Usually, when I'm going deep in a new technology, I write a simple CRUD for a table with a few simple fields. Here's what I think I will need:

  • JDO / JPA or something like Objectify /Twig "entity" class (my domain model)
  • Gwt-RPC knowledge, I mean, for example, do I need DTOs?

Can anyone address me in the right direction? Or better, a good crud example?


I think this question's been answered already. I like the stockwatcher tutorial also. It will also show you how to migrate to GAE once you're done.

This is one of examples created by me, hope it helps,
