VIEW: Faceletsįacelets is the view declaration language used to build JSF views and reusable composite components. In a later article, I will look a little deeper at CDI managed beans and the role they play. JSF is really an MVC framework in the classical sense, where the view is built using the Facelets declaration language and the model is represented by the CDI managed beans and the controller is taken care of by the JSF engine itself. It does this in order to separate the internal representations of data from the manner in which that data is presented. MVC is an architectural pattern for implementing user interfaces that divide a web application into three logically connected parts. Let’s start with a look at the Model View Controller design pattern otherwise known as just MVC. The JSF API includes many conveniences that allow a developer to deliver a high-quality user experience out of the box and with very little design knowledge. Fortunately, this is not too difficult to achieve with the help of Java EE APIs like JSF. This is the way users interact with your site and should be as user-friendly as possible. The presentation layer is responsible for what your visitors will see when they visit your website. Well, the layer I about talking about in this article is the presentation layer. Java EE applications are typically layered applications. ![]() I will explain how AJAX is natively supported and just how pluggable the eco-system is by looking at alternative templating frameworks such as Primefaces. #Alternative class for icefaces javascript context how to#I will introduce you to the MVC design pattern and how to use it and you will discover the Facelets view language and how it is used, how data and events are bound to the context and how this is achieved via expression language. When building a web application we provide the end user with a way to interact with our application and this is what JSF provides. In part 1 I introduced the basic idea behind JavaServer Pages (JSF) and in part 2 I introduce the Facelets declaration language. #Alternative class for icefaces javascript context series#This is a two-part series in which I look at JSF 2 and how it fits into the Java EE ecosystem. ![]()
