Apache MyFaces 1.2 Web Application Development

Overview of this book

Hypes and trends (such as Web 2.0) cause a change in the requirements for user interfaces every now and then. While a lot of frameworks are capable of meeting those changing requirements, it often means you as a developer need in-depth knowledge of web standards, such as XHTML and JavaScript. A framework like Apache MyFaces that hides all details of how the page is rendered at the client and at the same time offers a rich set of tools and building blocks could save you a lot of time, not only when you're building a brand new application but also when you're adapting an existing application to meet new user interface requirements.This book will teach you everything you need to know to build appealing web interfaces with Apache MyFaces and maintain your code in a pragmatic way. It describes all the steps that are involved in building a user interface with Apache MyFaces. This includes building templates and composition components with Facelets, using all sorts of specialized components from the Tomahawk, Trinidad, and Tobago component sets and adding validation with MyFaces Extensions Validator.The book uses a step-by-step approach and contains a lot of tips based on experience of the MyFaces libraries in real-world projects. Throughout the book an example scenario is used to work towards a fully functional application when the book is finished.This step-by-step guide will help you to build a fully functional and powerful application.

Of course, because it is an open source framework, anyone has the opportunity to extend and modify the framework to fit his needs. This can be a challenging job, even for advanced programmers. Everyone who has the time and knowledge should be encouraged to do so, as they can help in improving and expanding the ExtVal framework, or any other part of MyFaces. However, this section will focus on an easier way to expand the possibilities of the ExtVal framework: by using add-ons.

Getting add-ons for ExtVal

As ExtVal is a relatively new project and is not yet widely used, there are currently no "third party" open source add-ons for ExtVal. However, the lead developer of the ExtVal project has created some very useful add-ons. The following tables give an...
