J2EE vs ADF

Challenges Faced when Building J2EE Applications

• Building J2EE applications can be complex.
• Development time can be extensive.
• Choosing and implementing appropriate design patterns can be overwhelming.
• “Do it yourself” applications often repeat existing application code.
• A large portion of “do it yourself” code is dedicated to common tasks.
• The more code you write, the greater the chance of errors.
• An application framework is needed.

Oracle Application Development Framework
