JSF 1.2 Components

By: IAN HLAVATS

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 charts


The ICEfaces component library includes support for the open source jCharts project. This project provides a wide variety of chart objects that are rendered as JPEG images in the browser. We will look at how to render some of these charts using the ICEfaces<ice:outputChart> tag.

Rendering a stacked bar chart

Our first example demonstrates how to render a stacked bar chart using a static data set declared in our JSF page. This example renders a chart that displays unit test results for a series of test suites. The data is hardcoded in the data attribute of the tag. The values in a series are separated by commas, while the series themselves are separated by a colon. It is important that the number of labels and the number of series are equal.

<ice:outputChart type="barstacked" chartTitle="Unit Test Results" xaxisLabels="Suite 1, Suite 2, Suite 3" yaxisTitle="Test Methods" xaxisTitle="Test Suites" labels="pass, fail" data="70, 30, 10 : 10, 50, 70" colors="green, red...
