A step-by-step example-packed guide to learning professional application development with Direct Web Remoting

The initial part guides the reader through the features of DWR and how it works to make the developer ready for practical implementation. The later part contains plenty of code (with explanations) and graphical interface-driven step-by-step examples, which the reader can try out while surfing through the book to learn by doing. This book is written for competent Java developers and assumes that you are a professional rather than hobbyist. You should be familiar with the concepts of programming, Web 2.0, and AJAX.

This practical guide shows you how to make your Java web applications more responsive and dynamic by incorporating new Ajaxian features, including suggestion lists, drag-and-drop, and more. Java developers can choose between many different ways of incorporating Ajax, from building JavaScript into your applications "by hand" to using the new Google Web Toolkit (GWT). Ajax on Java starts with an introduction to Ajax, showing you how to write some basic applications that use client-side JavaScript to request information from a Java servlet and display it without doing a full page reload. It also presents several strategies for communicating between the client and the server, including sending raw data, and using XML or JSON (JavaScript Object Notation) for sending more complex collections of data. The book then branches out into different approaches for incorporating Ajax, which include: The Prototype and script.aculo.us Javascript libraries, the Dojo and Rico libraries, and DWR Integrating Ajax into Java ServerPages (JSP) applications Using Ajax with Struts Integrating Ajax into Java ServerFaces (JSF) applications Using Google's GWT, which offers a pure Java approach to developing web applications: your client-side components are written in Java, and compiled into HTML and JavaScript Ajax gives web developers the ability to build applications that are more interactive, more dynamic, more exciting and enjoyable for your users. If you're a Java developer and haven't tried Ajax, but would like to get started, this book is essential. Your users will be grateful.

Ajax (Asynchronous JavaScript and XML) is the ultimate web programming methodology for producing dynamic, rich web experiences. Java developers are crying out for guides showing how to add Ajax functionality to web applications, and this book meets their needs with Pro Ajax and Java. This is the book every Java developer needs to become expert in Ajax. The authors provide the reader with the perfect Java/Ajax toolkit to get started quickly, exploring Ajax development in detail using the 4 most popular Java web application frameworks: Struts, Spring, JSF, and Tapestry.

This book will save Java developers countless hours of development time by providing seven complete Ajax applications to learn from and adapt for use in their own projects. The applicaions include an online calendaring/scheduling system, a FlickrTM-style photo gallery application, and an Ajax role-playing game. The book also details the set-up of a perfect Java/Ajax development environment in which to construct the applications; Java technologies covered include Apache, Ant, Ajax Tags, Struts, Prototype, DWR, Dojo, and more. This is the first book of its kind, aimed at Java/Ajax developers.

Ajax, the popular term for Asynchronous JavaScript and XML, is one of the most important combinations of technologies for web developers to know these days. With its rich grouping of technologies, Ajax developers can create interactive web applications with XML-based web services, using JavaScript in the browser to process the web server response. Taking complete advantage of Ajax, however, requires something more than your typical "how-to" book. What it calls for is Ajax Hacks from O'Reilly. This valuable guide provides direct, hands-on solutions that take the mystery out of Ajax's many capabilities. Each hack represents a clever way to accomplish a specific task, saving you countless hours of searching for the right answer. A smart collection of 80 insider tips and tricks, Ajax Hacks covers all of the technology's finer points. Want to build next-generation web applications today? This book can show you how. Among the multitude of topics addressed, it shows you techniques for: Using Ajax with Google Maps and Yahoo Maps Displaying Weather.com data Scraping stock quotes Fetching postal codes Building web forms with auto-complete functionality Ajax Hacks also features a number of advanced hacks for accelerated web developers. Discover how to create huge, maintainable bookmarklets, how to use client-side storage for Ajax applications, and how to call a built-in Java object from JavaScript using Ajax. The book even addresses best practices for testing Ajax applications and improving maintenance, performance, and reliability for JavaScript code. The latest in O"Reilly's celebrated Hacks series, Ajax Hacks smartly complements other O'Reilly titles such as Head Rush Ajax and JavaScript: The Definitive Guide.

This book discusses what Ajax is and what it means to Web developers, as well as the technologies behind Ajax applications.

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.

The Ajax craze is sweeping the world, and there is no shortage of libraries from which to choose to make it all easier to develop. One of those libraries has risen near the top in the Java space, and that library is DWR. DWR, or Direct Web Remoting, allows you to treat your Java classes running on the server as if they were local objects running in the browser, bringing the full power of your server–side business logic to the client without the usual problems that entails. In this book, you will: Explore DWR and all it offers Find six full, working applications that use DWR, instead of a lot of theoretical musings Learn by example, more importantly, by doing, as you tear the applications apart, see what makes them tick, and even extend them at your own pace In the end, you’ll have a great feel for what DWR offers and how Ajax can bring the world of Web 2.0 to your doorstep, and you’ll have a good time doing it. What you’ll learn Call a server–side object in a snap and make it look like any local JavaScript call to boot Provide a strong security mechanism for securing your server-side code Integrate with many of the most popular frameworks out there Provide not only Ajax but Comet capabilities (sometimes called reverse Ajax) Dig into Ajax using DWR in a practical and hacking kind of way starting with a webmail client and Wiki projects Build a simple file manager application and an online timesheet system Complete a DWR–based game project Who this book is for Web application developers, senior projects leads, and application architects.
