The lines are broken to accommodate the book print layout, but the value of the href attribute is what the browser needs to know to fetch the CSS resource With @FacesRenderer and @ResourceDependency in place, let s continue with the code for AppleMobileBodyRenderer The actual CSS style sheet in this example is really just a placeholder A production solution would obviously have more content For completeness, it is shown here:

The getFamily( ) and getRendererType( ) methods are abstract in the base class, so we must override them here with concrete values Finally, we can cover encodeBegin( ) We need to call into the HTML_BASIC version of the body Renderer, but we have to do so in such a way that we can inject our own style attribute into the rendered <body> element In this case, we re writing out markup to tell the browser to use bggif from the resource library as the background image for the <body> The rendered markup is show here:

The last element in our working example is to add the existing HtmlHelloWorldRenderer to the AppleMobileRenderKit We could either modify the @FacesRenderer annotation on the existing Java code or simply declare it in the XML For extensibility, let s use the latter approach The complete faces-configxml example is shown here:

This completes our discussion of Java-based custom UIComponents and Renderers The remainder of the chapter will return to composite components and end with the complete vt:loginPanel example, including how to package this example into a selfcontained jar that can simply be dropped into the WEB-INF/lib of any JSF2 application
Advanced Composite Component Development
The preceding discussion on composite components included a simple login panel component In this section, we will revisit composite components and describe the more advanced aspects of this feature
Creating a Backing Class for <vt:loginPanel>
When the page author includes <vt:loginPanel> tag in the page, the author is actually including a whole subtree of components, rooted at the top-level component, that stands behind the actual <vt:loginPanel> tag When developing advanced custom components, it is frequently necessary to implement behavior using actual programming language code, and not just XHTML markup In such cases, it is useful to create a backing class for the composite component This is exactly analogous to the backing bean concept introduced in 5; the only difference is the backing object must be an actual UIComponent instead of a POJO The <vt:loginPanel> included in 10 does exactly this
FACELETS I NSIGHT It might seem tempting to just put the Java code for the backing class straight
into the page, as with JSP Scriptlets Rather than pollute the design of Facelets by introducing something like Scriptlets, Jacob Hookom, the inventor of Facelets, made a different choice: just don t provide the feature This is consistent with the philosophy that Facelets is simply a way to let page authors lay out and configure UIComponent instances If you want programming language code, put it in a programming language source file, not an XML file The Composite Component feature honors Jacob s design choice by making it very easy to associate code with a composite component
As with many things in JSF2, there is a convention that can be followed to associate a real Java class as the top-level component for a composite component The accompanying sidebar shows you the rules for how the top-level component is created
