What is OA Framework?

Oracle Application Framework is a J2EE framework developed by Oracle for extending the E-Business Suite. OA Framework follows the MVC Architecture which is a widely accepted framework for web based applications. In short a Framework is nothing but a partially built application which can be extended to suite the business needs. For example when you build a new application you have to take care of at least below things:
- Authentication System(Login and User Management)
- Security
- Accessibility
- User Personalization
- User Extensible Layer

OA Framework has all the above features and other important EBS features built in. This allows the Developer to concentrate on business logic and let the framework handle the technology.

By using OA Framework a developer can:

· Build new Self Service Pages for EBS
· Personalize the Self Service pages
· Extend the Self Service (seeded) pages
