Overview of this book

A homogenous guide integrating the features of JSF 2.x (2.0, 2.1 and 2.2), following a “learning through examples” paradigm with its main focus on the advanced concepts of JSF. If you are a web developer who uses JSF, this is the book for you. Catering to an intermediate-advanced audience, the book assumes you have fundamental knowledge of JSF. It is intended for the developer who wants to improve their skills with the combined power of JSF 2.0, 2.1, and 2.2.

Chapter 1. Dynamic Access to JSF Application Data through Expression Language (EL 3.0)

Java Expression Language (EL) is a compact and powerful mechanism that enables dynamic communication in JSP and JSF-based applications (including development frameworks based on JSF such as PrimeFaces, ICEfaces, and RichFaces); we embed expressions in the presentation layer to communicate with the application logic layer. EL provides bidirectional communication, which means that we can expose application logic data to the user, but we also can submit user data to be processes. Generically speaking, EL can be used to populate HTTP requests with user data, to extract and expose data from HTTP responses, to update HTML DOM, to conditionally process data, and much more.

Note

Commonly, EL expressions will be present in JSP and JSF pages, but they can also appear outside, in faces-config.xml, for example.

In this chapter, you will see how to use EL in web pages to communicate with managed beans, which is the most common case in JSF applications. We will cover the following topics:

  • EL syntax, operators, and reserved words
  • EL immediate and deferred evaluation
  • EL value and method expressions
  • The conditional text in JSF
  • Write a custom EL resolver
