JSF and MVC

JSF was developed integrating MVC design pattern so that applications can be designed well with greater maintainability. To understand this we need to understand what is MVC design pattern, how MVC helps to design and maintain an application.The MVC design pattern is divided into three separate parts: Model: handles data and logic. View: handles output (presentation) Controller: handles processing of an application. Controllers are used to process user actions. In JSF, Model part (Business logic) is handled by the Managed Beans (backing beans). View is handled by UI Components. Controller is Faces Servlet.
