Overview of this book

Oracle's Application Development Framework (ADF) for Fusion Web Applications leverages Java EE best practices and proven design patterns to simplify constructing complex web solutions with JDeveloper, and this hands-on, task-based cookbook enables you to realize those complex, enterprise-scale applications. With the help of real-world implementations, practical recipes cover everything from design and construction, to deployment, testing, debugging and optimization. This practical, task-based cookbook takes you, the ADF developer, on a practical journey for building Fusion Web Applications. By implementing a range of real world use cases, you will gain invaluable and applicable knowledge for utilizing the ADF framework with JDeveloper 11gR2. "Oracle JDeveloper 11gR2 Cookbook"ù is a task-based guide to the complete lifecycle of Fusion Web Application development using Oracle JDeveloper 11gR2 and ADF.You will get quickly up and running with concepts like setting up Application Workspaces and Projects, before delving into specific Business Components such as Entity Objects, View Objects, Application Modules and more. Along the way you will encounter even more practical recipes about ADF Faces UI components and Backing Beans, and the book rounds off by covering security, session timeouts and exceptions.With "Oracle JDeveloper 11gR2 Cookbook"ù in hand you will be equipped with the practical knowledge of a range of ready to use implementation cases which can be applied to your own Fusion Web ADF Applications.

Introduction


Backing (also referred to as managed) beans are Java beans referenced by JSF pages in an ADF Fusion web application through Expression Language (EL). They are usually dedicated to providing specific functionality to the corresponding page. They are part of the ViewController layer in the Model-View-Controller architecture. Depending on their persistence in memory throughout the lifetime of the application, managed beans are categorized based on their scope: from request (minimal persistence in memory for the specific user request only) to application (maximum persistence in memory for the duration of the application). They can also exist in any of the session, view, pageFlow, and backingBean scopes. Managed bean definitions can be added to any of the following ADF Fusion web application configuration files:

  • faces-config.xml: The JSF configuration file. It is searched first by the ADF framework for managed bean definitions. All scopes can be defined, except for view, backingBean...
