Wicket is a Java web application framework that takes simplicity, separation of concerns and ease of development to a whole new level. Wicket pages can be mocked up, previewed and later revised using standard WYSIWYG HTML design tools. Dynamic content pro
Where possible, creating Web applications — including Ajax-based applications — in a RESTful way avoids a large class of bugs. However, a pitfall of REST (REpresentational State Transfer) is sending duplicate data across similar XMLHttpRequests. This tip shows how the moderate use of session cookies can maintain just enough server-side state to significantly reduce client-server traffic, while still allowing fallback to cookie-free operation.
Today’s leading web applications are increasingly built on Web 2.0 principles: rich user interface, lightweight integration of multiple data sources, rapid evolution of applications, and user control over both content and context. Web 2.0 promises to expand the functionality of core business applications, knit together multiple services, and deliver a feature-rich user interface to enhance the customer experience and employee productivity.
The Google Web Toolkit (GWT) has attracted a lot of attention lately as a way to make it easier for developers to add AJAX Web 2.0 features to their applications. Like other approaches, the designers of GWT have tried to insulate developers from having to deal with the underlying JavaScript, which implements these features. GWT achieves this goal of simplifying the creation of advanced client-side JavaScript widgets by generating them from Java code.
