New face of oracle ADF

JSF - a New View on Oracle ADF

In its efforts of trying to make J2EE simpler, Oracle has been providing J2EE best practices, such as design patterns and application infrastructure in a framework it calls ADF (Application Development Framework). What is really interesting with ADF is that it is platform independent, as it will run on any J2EE compliant application server. Better yet, it provides options for every J2EE layer and development life-cycle phase, and you can use anyone you like. You are not forced to use all or nothing.

Oracle ADF is based on the Model-View-Controller (MVC) design pattern. View layer, which provides the user interface of an application. The view layer uses various markup languages to render the user interface, and it can be web-based, client/server based, a wireless implementation, or even telnet based. The focus is specifically on JavaServer Faces (JSF). Faces, as it's also known, not only provides a view layer, but also a navigation capability, similar to that of Struts and what is called backend beans or managed beans, where you can put your business logic and the interaction with the data sources. With that alone you could start building applications, as Faces is an MVC framework in its own.
