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.

Overriding bindParametersForCollection() to set a view object bind variable


There are times when you need to programmatically set the value of a bind variable used in the view object query. One way to accomplish this task is by overriding the view object method bindParametersForCollection() and explicitly specifying the value for the particular bind variable. This technique comes handy when the bind variable values cannot be specified in a declarative way, or the bind variable value source changes dynamically at runtime.

This recipe will show how to provide a default value for a bind variable used in the view object query if a value has not already been specified for it.

Getting ready

You will need to have access to the shared components workspace that was developed in the Breaking up the application in multiple workspaces recipe in Chapter 1, Pre-requisites to Success: ADF Project Setup and Foundations. Additional functionality will be added to the ExtViewObjectImpl and ExtApplicationModuleImpl...
