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.

Detecting and handling session timeouts


Each time a client request is sent to the server a predefined, application-wide, configurable session timeout value is written to the page to determine when a session timeout should occur. A page is considered eligible to timeout if there is no keyboard, mouse or any other programmatic activity on the page. Moreover, an additional application configuration option exists to warn the user sometime prior to the session expiration that a timeout is imminent.

In this recipe, we will see how to gracefully handle a session timeout by redirecting the application to a specific page, the login page in this case, once a session timeout is detected.

Getting ready

You will need to create a skeleton Fusion Web Application (ADF) workspace before you proceed with this recipe. For this purpose, 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 and...
