The RichFaces framework contains many JSF components to add Ajax to our applications in a very simple way, without needing to know anything about JavaScript (but if you know it, you have more features to use the framework inside your personalized JS code).

There are a lot of components for different kinds of tasks (such as interaction, input, output, drag-and-drop, validation, and so on). We are going to explain how they work every time we use them in the forthcoming chapters.

Throughout the book, we are going to develop an application using RichFaces. While doing so, we'll see how those components work in practice using real examples that cover all of their functionalities.
