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.

Chapter 8. Integrating with the Backend

As the MyFaces project is largely about view technologies, we have focussed on the view layer until now. For the sake of simplicity, we did not care about persisting our data in a database or something similar. However, in a real-world application, we do need a persistence solution most of the time. That’s why we’ll have a quick look at integrating our JSF web application with a backend solution. We will only look at some basics here, as lots of books could be written about backend technologies. (And luckily, many good books on the topic are already available.) This chapter focuses on using Java persistence, as it is included within the Java EE standard without the use of any additional libraries.

In this chapter we will learn about the following topics:

  • Basic knowledge about the Model-View-Controller design pattern

  • Basic knowledge about Enterprise JavaBeans (3.0)

  • Basic knowledge about the Java Persistence API (1.0)

  • Using Enterprise JavaBeans (EJB) facades...
