Roma <Meta> Framework
Roma allows you to develop enterprise level Java applications with low effort following a real Domain Driven Design approach. It's a new way to conceive the application: anything is a POJO, from the GUI forms to the persistent objects.
Using the Meta-Framework approach you can integrate the latest breaking technology in your application without modifying your domain and application logic because they are really decoupled.
