Seam 2.x Web Development

Overview of this book

The Seam framework from JBoss allows developers to use JSF, Facelets, EJB, and JPA to write conversational web applications. But you will first have to learn how these standard technologies are integrated using Seam and how they can be built upon using additional Seam components. If you need to build a Java web application fast, but don't have time to learn all these complex features, then this book is for you. The book provides a practical approach to developing Seam applications highlighting good development practices. It provides a complete walk through to develop Web applications using Seam, Facelets, and RichFaces and explains how to deploy them to the JBoss Application Server. You can start using key aspects of the Seam framework immediately because this book builds on them chapter by chapter, finally ending with details of enterprise functionality such as PDF report generation and event frameworks. First, the book introduces you to the fundamentals of Seam applications, describing topics such as Injection, Outjection and Bijection. You will understand the Facelets framework, AJAX, database persistence, and advanced Seam concepts through the many examples in the book. The book takes a practical approach throughout to describing the technologies and tools involved. You will add functionality to Seam applications after you learn how to use the Seam Generator RAD tools and how to customize and fully test application functionality. Hints and tips are provided along the way of how to use Seam and the JBoss Application Server.

Preface

Chapter 9. Seam and AJAX

With the advent of Web 2.0 technologies, users have demanded more interactive web applications. Typically, AJAX technologies are used to provide a high level of interactivity within web applications. In this chapter, we will discuss how AJAX can be used with Seam applications using both Seam Remoting and AJAX4JSF. In particular, we'll pay attention to:

  • Seam Remoting

  • Configuring applications to use Seam Remoting

  • Developing Seam Remoting clients and servers

  • Debugging Seam Remoting applications

  • AJAX4JSF

  • Configuring applications to use AJAX4JSF

  • Some of the more common AJAX4JSF tags

What is AJAX?

AJAX (Asynchronous JavaScript and XML) is a technique rather than a new technology for developing highly interactive web applications. Traditionally, when JavaScript is written, it uses the browser's XMLHttp DOM API class to make asynchronous calls to a server-side component, for example, servlets. The server-side component generates a resulting XML package and returns this to the client...
