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.

Setting up ExtVal


As with all other libraries, we start by downloading ExtVal and installing it in our project. As with many other JSF libraries, the ExtVal project has different branches for JSF 1.1 and 1.2. The first two digits of ExtVal’s version number are the JSF version they are made for. So ExtVal 1.1.x is the xth version of ExtVal for JSF 1.1, whereas ExtVal 1.2.x is the xth version for JSF 1.2. Versions of ExtVal are not released very often. At the time of writing this book, only two official releases have been published for each branch. According to the lead developer of ExtVal, a third release (1.1.3 and 1.2.3) is in the works for both branches, as well as a first release from the new JSF 2.0 branch.

Apart from stable releases, ExtVal offers snapshot builds that are created on a regular basis. The snapshots are created manually, which gives some guarantees about the quality compared to automatically-created daily releases. No snapshots with major bugs will be created. According...
