The application, deployed on CloudBees java platform, leverages ADF Faces (view) and Task Flows (controller) part of the stack. The application is not supposed to be stable and up all the time yet (CloudBees is not officially certified to run ADF).
According to recent news, Oralce public cloud is going to be generally available soon, so it might be interesting and useful for community to see more live ADF samples in a future.
Update 1: Oracle public cloud platform with 100+ applications already announced - registration for access available here.
In any case, your feedback on this experiment is appreciated - is the sample running or not :) ?
Update 2: The sample app together with a description of how to use JDeveloper R2 Maven integration to build and package it is available in this blog post.
Update 3: More categorized ADF samples (constantly growing number) created by members of the ADF EMG group are now available at ADF EMG Samples Wiki page!
