CHAPTER 6: Component-Based Web Development Using JSF 2 277

Life Cycle of a JSF Application

Unlike Struts and Spring Web MVC, the JSF life cycle performs the following request-processing
tasks in well-defined phases during which specific tasks are performed:

   Checking whether the incoming data is valid

   Triggering application logic to fulfill the request

   Binding the field properties directly to properties of the model and having their

values updated upon form submissions

   Rendering the response to the client

The following are the six phases of the JSF application life cycle, as illustrated in Figure 6-14:

   Restore View phase

   Apply Request Values phase

   Process Validation phase

   Update Model phase

   Invoke Application phase

   Render Response phase
