Flex 3 with Java

Overview of this book

Flex 3 is a great technology for developing Rich Internet Applications for the Web as well as for the desktop. If you are a developer looking to design great-looking and sophisticated user interfaces that resemble desktop-based applications, and want to utilize an existing server technology such as Java to develop RIAs, this book is for you. Targeting developers who want to get started with Adobe Flex 3 programming, this simple and clear handbook introduces Flex technology quickly and straightforwardly. Utilizing your existing knowledge of Java, it gives you the insight and hands-on experience to program with Flex 3. This book provides comprehensive information on various aspects of Flex 3 and ActionScript 3.0. These include developing simple applications, handling events, creating custom components and events, using RPC services, integration with Java and BlazeDS, styling and formatting, and how to package and deploy Flex applications. You will start with downloading, installing and configuring Flex 3 SDK and Flex Builder 3 and learn basic concepts such as what MXML and ActionScript are, understanding UI components, controls, compilers, and more. Further you will develop simple applications and slowly advance into more depth where you will learn advanced concepts such as creating custom components, debugging, integrating with Java, using RPC services, styling, internationalizing, and deploying Flex applications, and more. One of the things you're really going to love about this book is that you will develop a full-blown e-commerce application using a combination of Flex 3, ActionScript 3.0, BlazeDS 3.2, and Java. At the end of the book you will have the knowledge and experience needed to develop Rich Internet Applications.

Chapter 9. Debugging Techniques

It is very important to understand the debugging techniques and tooling available with any Software Development Kit (SDK), and Flex is no different. Traditionally, debugging web applications—especially the client-side code—has been a cumbersome task. One of the core strengths of Flex is its ability to debug client-side Flex application code. The Flex SDK provides built-in debugging tools for speeding up the development of web applications.

The Flex SDK includes a fully-featured command line debugging tool called FDB (Flash Player Debugger). This tool can be used to debug your application. Although you can use the Flex Builder to do the same thing, it is good to have a free debugging tool as part of the SDK itself. We will not be covering this command line tool in depth.
