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.

Preparing a database environment


Before we can start implementing the Model layer of our application, we first have to create a database environment.

Creating a database

In our example application, we are going to use Java DB, which is a relational database that is bundled with the Java Development Kit (JDK). Of course, any other database can be used, but Java DB seems a good choice for an example application because everyone who has a JDK already has it installed. For completeness, we’re starting out by setting up the database environment.

Note

Java DB is nothing more than a rebranded version of Apache Derby, an open source relational database implemented entirely in Java. The version bundled with the JRE 1.6 is Derby 10.4. Extensive documentation about Java DB/Derby can be found on the Apache Derby website at http://db.apache.org/derby/docs/10.4/. We will refer to the database as Java DB. But wherever Java DB is mentioned, you can read Derby as well if you like.

The Java DB database has several...
