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.

Laying out components on the screen


The Trinidad framework includes a number of useful tags for laying out components on the screen. Some of these tags handle more specific tasks such as laying out a set of controls horizontally, vertically, or in some other arrangement, while other tags handle more general tasks such as abstracting the "page" concept and breaking it up into smaller, more manageable sections.

Let's look at how to use Trinidad components to handle some of the more specific layout situations we may encounter in our web development activities.

Rendering a row layout

The HtmlRowLayout component is rendered as a sequence of HTML<tr> and<td> elements using the<trh:rowLayout> tag. This tag's layout logic is to render each of its child tags as a single HTML table cell within a single HTML table row.

<trh:rowLayout styleClass="row-layout">
<tr:outputText value="Hello" />
<tr:outputText value="World" />
<tr:outputText value="How" />
<tr...
