The sample, available at github, contains a list of NetBeans (maven) projects showing the design and the usage of bean validation constraints.
One interesting aspect might be also the usage of a common data model on a service provider and consumer side. It allows to reuse bean validation constrains together wit a model on a service provider and consumer side.
Readers of this blog might already got a notice about Oracle ADF Essentials - JEE end-to-end framework - free to develop and deploy.
The sample project is going to be used in a following blog posts to extend a functionality on a service consumer side ( view and controller) by leveraging ADF task flows, data controls and ADF Faces - features (actually a part of them - there is more) provided by ADF Essentials.
In case you are interested in building ADF applications on a top of heterogeneous data sources - stay tuned:)
