GraniteDS introduces an ActionsScript3 implementation of the Bean Validation specification and provides code generation
tools integration so that your Java constraint annotations are reproduced in your AS3 beans
history is persisted in the database
by means of a JPA entity bean and those objects are serialized back to the Flex client each time you enter a new name.
In short, it provides much easier configuration of the backend infrastructure and services you want to expose to the client and it integrates perfectly with the Spring application contexts and the Spring programming model in general.
