Oracle Middleware 12c: Build Rich Client Applications with ADF Ed 1

The Oracle Application Development Framework (Oracle ADF) is an end-to-end application framework that builds on J2EE standards and open-source technologies to simplify and accelerate implementing service-oriented applications. If you develop enterprise solutions that search, display, create, modify, and validate data using web,wireless, desktop, or web services interfaces, Oracle ADF can simplify your job.
