A central theme of web application design is the separation of presentation and business logic. JSF uses beans to achieve this separation. JSF pages refer to bean properties, and the program logic is contained in the bean implementation code. Because beans are so fundamental to JSF programming, we discuss them in detail in this chapter.

The first half of the chapter discusses the essential features of beans that every JSF developer needs to know. We then present an example program that puts these essentials to work. The remaining sections cover more technical aspects about bean configuration and value binding expressions. You can safely skip these sections when you first read this book, and return to them when the need arises.
