PrimeFaces is the de facto standard in the Java web development. PrimeFaces is a lightweight library with one jar, zero-configuration, and no required dependencies.

"PrimeFaces Cookbook" covers over 100 effective recipes for PrimeFaces 3.x which is a leading component suite to boost JSF applications. The book's range is wide‚Äí from AJAX basics, theming, and input components to advanced usage of datatable, menus, drag & drop, and charts. It also includes creating custom components and PrimeFaces Extensions.You will start with the basic concepts such as installing PrimeFaces, configuring it, and writing a first simple page. You will learn PrimeFaces' theming concept and common inputs and selects components. After that more advanced components and use cases will be discussed. The topics covered are grouping content with panels, data iteration components, endless menu variations, working with files and images, using drag & drop, creating charts, and maps.

Understanding the structural and skinning CSS


Each component is styled with CSS and contains two layers of style information—structural or component-specific and skinning or component-independent styles.

In this recipe, you will understand the difference between these two types of CSS, learn some useful selectors, and see an exemplary styling of the PickList component in the generated HTML.

Getting ready

To learn about different layers of style information, you can go to the PrimeFaces ShowCase (http://primefaces.org/showcase/ui/home.jsf) and look at it in the Firefox browser with an installed Firebug add-on (http://getfirebug.com). Firebug allows live editing, debugging, and monitoring CSS, HTML, and JavaScript in any web page. The add-on can be opened after its installation by navigating to Tools | Web Developer | Firebug or by pressing the F12 key. Another useful tool is built-in Developer Tools for the Google Chrome browser, which is similar to the Firebug.
