Tutorial on connecting Flex to Google App Engine (Java)

[Sekhar]

As you know, Google App Engine (Java) is here. It's standards-based and supports persistence though JPA/JDO, but if you want to interface it with a Flex app using AMF, your choices are kind of limited till AMF implementations like BlazeDS catch up.

We're just finishing up a project using Flex with GAE/J and have found that GraniteDS works really well. I've written a tutorial based on the experience, check out Cloud to RIA: Accessing Google App Engine (Java) Data Through Flex AMF (http://blog.allurefx.com/2009/05/cloud-to-ria-accessing-google-app.html).

If you're interested in the project itself, please check out SDNari (http://1.latest.sdnari.appspot.com). We're still working on it, would love your feedback on that as well.

There is an alternative "up-to-date" approach for connecting Flex (also Android) to Google AppEngine on the Midnight Coders' Blog, which is blog.themidnightcoders.com This approach uses WebORB for Java instead of Granite DS.

The blog post includes a screencast and link to documentation. The title of the blogpost is Java Object Access in Google AppEngine from Flex/Flash, Silverlight, JavaScript and Android.
