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.

Limiting the rows fetched by a view object


The ADF Business Components framework allows you to declaratively and/or programmatically set an upper limit for the number of rows that can fetched from the database layer by a view object. Declaratively, this can be accomplished through the view object Tuning section in the General page of the view object Overview editor. You can do this by selecting Only up to row number in the Retrieve from the Database section and providing a row count.

This can also be accomplished programmatically by calling a view object's setMaxFetchSize() method and specifying an upper row limit.

To globally set an upper limit for the number of rows that can be fetched by all view objects in an ADF Fusion web application, the global configuration setting rowLimit in the adf-config.xml configuration file can be used instead. Then, by overriding the framework getRowLimit() method, you can adjust this upper limit for individual view objects as needed. When an attempt is...
