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.

Working with trees

In desktop software applications, trees represent a convenient and intuitive type of control that users can interact with to perform a variety of tasks, such as navigating a file system, managing operating system users and groups, browsing threaded messages on an Internet newsgroup, exploring an XML document, and working with other types of hierarchically structured data.

The Tomahawk component library includes a number of components that can be used to implement tree controls for our JSF applications. Let's look at some examples of how we can integrate a tree component with our file management example to enable users to browse the files that they've uploaded to our web application.

Creating a tree

In this example, the<t:tree> tag is used to render a tree component on our JSF page. This time, instead of rendering the uploaded files as an ordered list, we render them as a dynamic tree.
