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.

Preface

Working with modal dialogs


Web browser support for modal dialogs is quite limited. To date, there is no standard browser support for rendering a complex modal dialog window. Fortunately, the ICEfaces library includes such a component.

Rendering a simple modal dialog

To render a simple modal dialog with ICEfaces, we can use the<ice:panelPopup> tag. This tag has a "header" and "body" facet to render the dialog title and message content, respectively.

The modal attribute of the tag expects a Boolean value that determines whether the dialog is modal or not. When this attribute is set to true, the dialog appears centered over a transparent gray background that covers the entire screen. When this attribute is set to false, the dialog is displayed next to the button and the background is not modified.

<ice:panelGroup style="height: 75px;">
<ice:panelGroup style="float:left">
<ice:outputLabel value="Modal Popup Message" for="modalMessageInput" />
</ice:panelGroup>
