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.

Rendering a UI component

Sometimes, it is desirable to include content from another view element as a single UI component. This enables us, for example, to use the rendered attribute on the included content to support conditionally rendered markup more easily, and is convenient for situations where a single component is expected (such as inside the<h:panelGrid> or<f:facet> tag).

The Facelets<ui:component> tag is similar to the<ui:composition> tag. In both cases, any content outside the tag is trimmed, but in the case of the<ui:component> tag, the content will be rendered within a UI component. Let's look at some examples of using the Facelets<ui:component> tag.

Including a UI component

The following example demonstrates that a Facelet containing a<ui:component> tag can be included just like a Facelet containing a<ui:composition> tag:
