Demo ApplicationEcho is an open-source framework for developing rich web applications. From the developer's perspective, Echo behaves as a user interface toolkit--like Swing or Eclipse SWT. AJAX technology is employed to deliver a user experience to web clients that approaches that of desktop-based applications. Echo applications can be created entirely in server-side Java code using a component-oriented and event-driven API (applies to Echo2 and Echo3) or as client-side applications written in JavaScript (applies to Echo3 only).

Echo3 is the next generation of the Echo platform. Echo3 features the ability to create applications in either client-side JavaScript or in server-side Java. It offers superior performance to Echo2, and a substantially easier API for creating custom AJAX components that will use custom HTML and JavaScript.
