<p>Mainly, the JSF Fundamentals video is dedicated to providing fundamental knowledge of controlling the communication aspects in JSF. Definitely, communication is the core of a JSF application and is one of the main aspects that dictate the architecture of such an application. Thinking of the big picture, you need to identify—right from the start—the main parts and how they will communicate with one another and with the end user.</p> <p>After selecting design patterns, drawing the UML diagrams, and sketching the architecture and the application flow, it's time to get to work and start implementing the communication pipes using forms, parameters, arguments, values, pages, beans, and so on. Fortunately, JSF provides many solutions for ensuring a powerful and flexible communication layer between JSF components and also between JSF and XHTML pages, the JavaScript code, and other third-party components. But, when something is powerful and flexible, it is typically hard to control and inappropriate usages will lead to poor results.</p> <p>This video is exactly what you need for shaping the communication aspects and for obtaining the knowledge that is essential in order to decide what, when, and how to use depending on your application. But, keep in mind that the JSF Fundamentals video is not trying to take you by the hand to show you the world of JSF as a beginner's guide.</p>
