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.

Preface

Using a session scope bean to preserve session-wide information


Information stored in the DBMS can be preserved for the duration of the user session by utilizing ADF business components to retrieve it, and a session scope managed bean to preserve it throughout the user session. Using this technique allows us to access session-wide information from any page in our application, without the need to create specific bindings for it in each page.

This recipe demonstrates how to access and preserve session-wide information by implementing the following use case. For each employee authenticated to access the application, its specific information will be maintained by a session-scoped managed bean.

Getting ready

You will need to create a skeleton Fusion Web Application (ADF) workspace before you proceed with this recipe. For this, we will use the MainApplication workspace that was developed in Breaking up the application in multiple workspaces, Chapter 1,Pre-requisites to Success: ADF Project Setup...
