What Java REST framework to use with App Engine and Android for students? [closed]

Question

I'm teaching a college course on mobile application development and would like to introduce my students to a REST framework for use with App Engine, to help them with data storage for the Android apps they're building. Could anyone recommend a Java REST framework for App Engine that meets the following criteria:

Must have:

• Easy learning curve
• Well-documented, with clear tutorials and sample programs
• Clean abstractions
• Free as in beer
• Works well with Eclipse

Nice to have:

• Android client
• Free as in speech

Not important:

• Able to support large query volumes
• Highly customizable

From my web searching, Restlet looks best. Is there any other framework I should consider?

Answer 1

Well, I would highly recommend play framework

Have a look at the video on the homepage

It has a gae module

With siena as a orm to handle gae datastore

From all the java frameworks I've seen so far, I think it has the easier learning curve,

• great documentation,

• a tutorial to develop a complete application

• very active and helpful community

• free as in beer and also as in speech

• highly scalable due to it's stateless out of the box design

• rest friendly

• highly customizable via it's modules and plugin approach

more over, taking into account it's for a college course, it's really easy to hack into the code, I could handle a couple of tickets and new features without any experience at all with java, just a couple of year developing web applications with php

other benefits

• it's really easy to start, no complicated setup involved, just download and unzip the file and your are ready

• great development experience, just fix the code and hit refresh, play autocompiles changes on the fly when running on development mode

• fast and lightweight

• fullstack, you don't have integrate cumbersome frameworks to make it work

• great errors report, no more endless error stack trace, just shows you the line with error

• no xml configuration anywhere around

• great support for tdd with selenium integrated test

I think the main advantage as a learning tool, is that it's possible to peek into the source code without feeling lost and the community support... The documentation is very clear, and you can learn a lot by just having a look at the source code...

Jax-RS...Restlet was written before this but was modified to implement Jax-RS.
