  Problem

  If you have ever used Hibernate, JPA or any other object-relational mapping (ORM) framework, you'll know that Session/EntityManager does all the hard work. However, there is no Session/EntityManger on the client side.

The proposed solution use a Spring/Hibernate/Maven code generation tool (SpringFuse) and explain how to use the generated project with a Flex application using BlazeDS
