JSF 1.2 Components

Overview of this book

Today's web developers need powerful tools to deliver richer, faster, and smoother web experiences. JavaServer Faces includes powerful, feature-rich, Ajax-enabled UI components that provide all the functionality needed to build web applications in a Web 2.0 world. It's the perfect way to build rich, interactive, and "Web 2.0-style" Java web apps. This book provides a comprehensive introduction to the most popular JSF components available today and demonstrate step-by-step how to build increasingly sophisticated JSF user interfaces with standard JSF, Facelets, Apache Tomahawk/Trinidad, ICEfaces, JBoss Seam, JBoss RichFaces/Ajax4jsf, and JSF 2.0 components. JSF 1.2 Components is both an excellent starting point for new JSF developers, and a great reference and “how to” guide for experienced JSF professionals. This book progresses logically from an introduction to standard JSF HTML, and JSF Core components to advanced JSF UI development. As you move through the book, you will learn how to build composite views using Facelets tags, implement common web development tasks using Tomahawk components, and add Ajax capabilities to your JSF user interface with ICEfaces components. You will also learn how to solve the complex web application development challenges with the JBoss Seam framework. At the end of the book, you will be introduced to the new and up-coming JSF component libraries that will provide a road map of the future JSF technologies.

Passing parameters from one Facelet to another


Including static content declared in another document is fine for view elements such as headers and footers, but what if we wanted to pass an object from one Facelet to another? The<ui:include> tag is more than a simple SSI tag; it has enhanced functionality that makes it possible to pass arbitrary data from one page to another.

Facelets supports the ability to pass parameters from one Facelet to another by nesting the<ui:param> tag inside a<ui:include> tag. Using the<ui:param> tag's name and value attributes, we can define named content that can be referenced by the included Facelet.

The next example demonstrates how to pass parameters to an included Facelet by using the<ui:param> tag within a<ui:include> tag. In this case, we include a Facelet that renders a customer list twice, and we pass different parameters to each one. In the first case, we render a list of male customers, and in the second case we...
