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.

Creating basic data tables


Most in-company systems contain a lot of data that can be displayed to users in an efficient way by using a data table. Tomahawk has a lot of components that cater to the display and editing of data in tables. This section focuses on these components. As an example, we will further expand the MIAS application to include a page that shows all of the kids that are in the database, along with their name, age, the date they were last scared by a monster, and a "braveness factor"—a value between 0 to 10 indicating how easy it is to scare the kid. A kid with braveness 10 is very brave and thus hard to scare.

The data to display is provided by a Java Bean called KidsList. This bean has a getKids() method that returns a java.util.List of the Kid objects. The Kid class defines a set of get and set methods that return things such as the first and the last name of the kid, his or her age, braveness factor, and so on.
