Google Web Toolkit Solutions: More Cool & Useful Stuff

Description

Google Web Toolkit (GWT) is an open source Java development framework that lets Java developers implement Ajax-enabled web applications. Instead of the hodgepodge of technologies that developers typically use for Ajax--JavaScript, HTML, CSS, and XMLHttpRequest--GWT lets developers implement rich client applications using pure Java, using familiar idioms from the AWT, Swing, and SWT. And GWT goes way beyond most Ajax frameworks by easily facilitating the implementation of desktop-like applications that run in the ubiquitous browser, where the richness of the user interface is limited only by the developer's imagination.

 

This book is not an introduction to GWT, that ground is covered, ad infinitum, in countless articles and blogs on the Web, and in other GWT books. Instead, this book focuses on the more advanced aspects of GWT that you will need to implement real world applications with rich user interfaces that previously required heavy lifting of JavaScript and other Ajax-related technologies. Each solution in this practical, hands-on book is more than a recipe. The sample programs are carefully explained in detail to help you quickly master advanced GWT techniques such as implementing drag and drop, integrating JavaScript libraries, using deferred commands, and advanced event handling methodologies.  Solutions in this book are in response to the most common yet complex obstacles developers run into with GWT.

 

Solutions covered include

·   Building custom GWT widgets, including both high-level composites and low-level components

·   Integrating web services with GWT applications

·   Incorporating the Script.aculo.us JavaScript framework into GWT applications

·   Combining Hibernate and GWT to implement database-backed web applications

·   Extending the GWT PopupPanel class to implement a draggable and resizable window

·   Creating a drag and drop module, complete with drag sources and drop targets

·   Deploying your GWT applications to an external server

·   Mastering the GWT's flex table

·   Using GWT widgets in legacy applications developed with other frameworks, such as Struts and JavaServer Faces
