JavaServer Faces (JSF) is the normal Java EE know-how for construction internet person interfaces. It presents a robust framework for constructing server-side functions, permitting you to cleanly separate visible presentation and alertness common sense. JSF 2.0 is an incredible improve, which not just provides many beneficial positive aspects but in addition vastly simplifies the programming version by utilizing annotations and ''convention over configuration'' for universal tasks.To assist you fast faucet into the facility of JSF 2.0, the 3rd variation of center JavaServer™ Faces has been thoroughly up to date to make optimal use of the entire new beneficial properties. The booklet includesThree absolutely new chapters on utilizing Facelets tags for templating, construction composite elements, and constructing Ajax applicationsGuidance on development strong functions with minimum hand coding and greatest productivity–without requiring any wisdom of servlets or different low-level ''plumbing''A entire clarification of the fundamental construction blocks–from utilizing normal JSF tags, to operating with info tables, and changing and validating inputCoverage of complicated initiatives, similar to occasion dealing with, extending the JSF framework, and connecting to exterior servicesSolutions to a number of universal demanding situations, together with notes on debugging and troubleshooting, as well as implementation info and dealing code for positive aspects which are lacking from JSFProven options, tricks, advice, and ''how-tos'' enable you use JSF successfully on your improvement projectsCore JavaServer™ Faces, 3rd version, offers every little thing you must grasp the strong and time-saving gains of JSF 2.0 and is the correct advisor for programmers constructing Java EE 6 net apps on Glassfish or one other Java EE 6-compliant program servers, in addition to servlet runners corresponding to Tomcat 6.

NOTE: The UserBean class implements the Serializable interface. This is not a requirement for a JSF managed bean, but it is nevertheless a good idea for session-scoped beans. Application servers can provide better management for serializable beans, such as clustering. From the Library of Wow! eBook 36 Chapter 2 ■ Managed Beans As you can see, the JSF developer does not need to write any Java code to construct and manipulate the user bean. The JSF implementation constructs the beans and accesses them, as described by the expressions in the JSF pages.

With deferred evaluation, the JSF implementation retains the expression and evaluates it whenever a value is needed. As a rule of thumb, you always use deferred expressions for JSF component properties, and you use immediate expressions in plain JSP or JSTL (JavaServer Pages Standard Tag Library) constructs. ) Backing Beans Sometimes it is convenient to design a bean that contains some or all component objects of a web form. Such a bean is called a backing bean for the web form. For example, we can define a backing bean for the quiz form by adding properties for the form component: @ManagedBean(name="quizForm") @SessionScoped public class QuizFormBean { private UIInput answerComponent; private UIOutput scoreComponent; public UIInput getAnswerComponent() { return answerComponent; } public void setAnswerComponent(UIInput newValue) { answerComponent = newValue; } public UIOutput getScoreComponent() { return scoreComponent; } public void setScoreComponent(UIOutput newValue) { scoreComponent = newValue; } ...
