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.

There are two files involved in tuning Trinidad: web.xml and trinidad-config.xml. Both of these files reside in the WEB-INF directory of the project.

trinidad-config.xml file

The trinidad-config.xml is a configuration file specific to Trinidad. It should be placed in the WEB-INF directory, under the root of a deployment file (JAR, WAR, or EAR). A minimal trinidad-config.xml looks like this:

<?xml version="1.0"?>
<trinidad-config xmlns="http://myfaces.apache.org/trinidad/config">
</trinidad-config>

Inside the<trinidad-config> element, several configuration elements can be added in a random order. They are covered in the rest of this section.

Although there is one single trinidad-config.xml file for a single application, it is possible to have different settings for (groups of...
