OEPE provides a set of plugins for the Eclipse IDE designed to create, configure, and run Oracle ADF applications.
The Oracle Application Development Framework (Oracle ADF) is an end-to-end application framework that builds on Java Platform, Enterprise Edition (Java EE) 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. Used in tandem, OEPE and Oracle ADF give you an environment that covers the full development lifecycle from design to deployment, with drag and drop data binding and visual UI design features built in.
