The Java RIA Framework

Jspresso is an innovative framework for building rich internet applications. Jspresso dramatically reduces the development cycles needed to get your corporate application up and running while not sacrificing quality, robustness and performance. Jspresso is not just another webapp framework. Jspresso based applications offer the exact same ergonomics as desktop applications while keeping an N-tier, server-centric architecture on a java backend. Jspresso-based applications can be deployed either in Adobe's Flex, Ajax (WingS), ULC and Swing, all on the same codebase and without a single specific line of GUI code. And last but not least, Jspresso is free.
