This book is about using JavaServer Faces to create and deploy interactive applications delivered to end users via a browser interface. JavaServer Faces is the component-based technology enabling easy development of such applications, especially applications of the type commonly needed in enterprise environments. JavaServerFaces: Introduction by Example is a to-the-point, 250-page introduction to an important technology that every Java Enterprise Edition programmer should know and be able to use.

JavaServer Faces: Introduction by Example takes you through building and deploying servlet-based web pages built around JavaServer Faces, Facelets, managed Java Beans, and prebuilt user-interface components. You'll learn to build user interfaces that run in the browser, to display data drawn from corporate databases, accept user input, deal with errors and exceptions, and more.

JavaServer Faces is an important user-interface technology for any Java developer to learn who works in an enterprise environment. JavaServer Faces: Introduction by Example is your no-nonsense guide to getting started right away in taking advantage of the technology's component-driven approach.

  • Introduces servlets, which are the basis for JavaServer Faces applications
  • Covers development and deployment of user interfaces in the browser
  • Demonstrates advanced techniques such as the use of AJAX

What you’ll learn

Within the sessionDestroyed method, another synchronization statement decrements the numberOfSessions field value by one, and then a couple of lines are printed to the server log indicating that a session has been destroyed and providing the new total number of active sessions.

In fact, the only difference in the two view pages is the use of the JSF expression #{} rather than the standard JSP value expression ${}. Thanks to the JSP 2.0 unified expression language, Java web developers now have an easy transition between the two technologies, and they now share many of the same expression language features.
