This book is for Java developers who want to create Ajax interfaces using the Google Web Toolkit (GWT). It focuses on useful, practical tasks from the first chapter. The book is aimed at programmers who want to use GWT to create interfaces for their professional web applications. It concentrates on the serious side of Ajax: creating powerful, productive applications for browser platforms. GWT Ajax Programming shows you how to create reliable user interfaces that enhance the user experience.

GWT is an open source Java software development framework that makes writing AJAX applications like Google Maps and Gmail easy for developers who don’t speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatibilities between web browsers and platforms, and JavaScript’s lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile. GWT lets you avoid many of these headaches while offering your users the same dynamic, standards-compliant experience. You write your front end in the Java programming language, and the GWT compiler converts your Java classes to browser-compliant JavaScript and HTML. (more…)

Web applications no longer need be powered by any one individual's data, and they don't need to be confined to the desktop. Developers can draw on a wealth of publicly available content, from providers such as Flickr, Amazon, Google, Twitter, and Last.fm, and combine it for use in their own applications. Adobe Integrated Runtime (AIR) makes it simple to bring previously web-only applications to the desktop, allowing them to run alongside traditional applications on an end user's computer.

In this book, you'll learn how to create mashup applications from the vast array of web services, feeds, and APIs using Adobe Flash and Flex together with HTML and JavaScript (Ajax). You'll be introduced to the various sources of information and the tools necessary to gather and reuse that information, and then you'll learn how to combine that content in a variety of ways.

You'll learn how to have desktop applications interact with online services such as Flickr, you'll learn how to use Amazon S3 for enterprise-level data storage, and you'll embrace technologies such as OpenID. In addition, you'll create abstract visualizations based on music sourced from Last.fm and consume Twitter content via RSS. You will also see how to use the Flash-native data format SWX along with PHP to create a Yahoo! weather widget.

Adobe Integrated Runtime (AIR) revolutionizes the way Rich Internet Applications (RIAs) are deployed. AIR supports two primary technologies, Flash and HTML/Ajax, in order to make desktop development something that every web developer can do. This book shows you how to set up a practical development environment and then walks you through eleven fully implemented AIR applications with source code that you can use as they currently exist or customize.

Each project begins by providing a discussion of architecture and design, followed by code implementation. You'll get hands-on knowledge of AIR application design and development that you can then use to build dynamic RIAs.

AIR (Adobe Integrated Runtime) is Adobe’s open-source technology that lets Web developers and programmers create Rich Internet Applications that run outside of any Web browser. This Visual QuickPro Guide teaches everything you need to know to begin creating applications that combine the rich experience of a traditional desktop application with the power and reach of the Internet. The book uses a visual, step-by-step approach and covers all the fundamental AIR concepts, without the fluff, confusing segues, and technical jargon that bog down so many other computer books. Author Larry Ullman has a well-earned reputation for writing books that are accessible, easy-to-follow, and, above all, useful. This book focuses solely on developing AIR applications using HTML and JavaScript, although formal knowledge of JavaScript is not required. (more…)

Asynchronous JavaScript and XML (Ajax) is a web technique used to transfer data between a browser and server asynchronously without posting the web page to the server. "Asynchronously" implies that the processing of the web page continues while the Ajax request is sent to the server and a response is received from the server. The web page, or section(s) of the web page, is refreshed with the Ajax response without reposting the web page. Ajax has the following advantages over non-Ajax web applications.

- Reduced response time and reduced server load, as the complete web page is not reposted.

- Reduced bandwidth of web applications as only data is transferred and the HTML format is applied in the browser.

- Separation of data, format and style.

The book covers web search and RSS Feed with Ajax as well as form validation with Ajax frameworks for Java, JSP, JSF, and PHP. It discusses using Ajax in Oracle JDeveloper and is IDE based. JDeveloper has the following advantages over Eclipse IDE.

- JDeveloper 11g provides an integrated JavaScript Editor for Ajax/Web development.

- It also provides a PHP extension.

- JDeveloper has a built-in support for JSF and for JDBC.

If you're a web developer with previous JavaScript and DOM scripting experience, Accelerated DOM Scripting with Ajax, APIs, and Libraries is perfect for you to take your knowledge up to the next level.

This book is about JavaScript and using the document object model—the conduit to the HTML document. This book is not about learning how to program JavaScript from scratch. It starts with the assumption that you have done some JavaScript development before and understand the JavaScript syntax. This book builds on top of that knowledge to give you a deeper understanding of DOM Scripting and how to apply that to your projects. It uses this new understanding to describe what JavaScript libraries are and show you how they can be applied to your project. The book will also explain Ajax and how best to plan and apply it to your projects. It explains how to build simple animation objects for adding movement to elements on the page. There are straightforward examples that demonstrate the techniques used throughout the book.

JavaScript has seen a resurgence in popularity over the past few years, and with it has come an exploration of the power of the language as well as what it can do within the browser. This book will explain techniques new and old—such as closures, encapsulation, and inheritance—that many are using and how you can best apply them to your own projects.

Is Ajax a new technology, or the same old stuff web developers have been using for years? Both, actually. This book demonstrates not only how tried-and-true web standards make Ajax possible, but how these older technologies allow you to give sites a decidedly modern Web 2.0 feel. Ajax: The Definitive Guide explains how to use standards like JavaScript, XML, CSS, and XHTML, along with the XMLHttpRequest object, to build browser-based web applications that function like desktop programs. You get a complete background on what goes into today's web sites and applications, and learn to leverage these tools along with Ajax for advanced browser searching, web services, mashups, and more. You discover how to turn a web browser and web site into a true application, and why developing with Ajax is faster, easier and cheaper. The book also explains: How to connect server-side backend components to user interfaces in the browser Loading and manipulating XML documents, and how to replace XML with JSON Manipulating the Document Object Model (DOM) Designing Ajax interfaces for usability, functionality, visualization, and accessibility Site navigation layout, including issues with Ajax and the browser's back button Adding life to tables & lists, navigation boxes and windows Animation creation, interactive forms, and data validation Search, web services and mash-ups Applying Ajax to business communications, and creating Internet games without plug-ins The advantages of modular coding, ways to optimize Ajax applications, and more This book also provides references to XML and XSLT, popular JavaScript Frameworks, Libraries, and Toolkits, and various Web Service APIs. By offering web developers a muchbroader set of tools and options, Ajax gives developers a new way to create content on the Web, while throwing off the constraints of the past. Ajax: The Definitive Guide describes the contents of this unique toolbox in exhaustive detail, and explains how to get the most out of it.
