Development is done in pure server-side Java — no Ajax-programming is needed. On the user side any modern web browser will do — no plugins are needed. As the framework is released with Apache license, it should get quite a lot of attention from commercial application developers."

Developers can build rich web applications easily with Java on the server-side, much like creating regular desktop applications with Swing or AWT. There is no need to know anything about HTML, Ajax or JSON working under the hood. Unlike the client-side RIA frameworks, like GWT or Flex, where one needs to implement both server and client, in IT Mill Toolkit you only implement the server application.
While being an extensive framework for RIA development, it is just one JAR that you can drop into any Java Web project and use side-by-side with other frameworks. This is also the only server-side Java toolkit where the extensions to the framework are also created in pure Java. If the (fairly extensive) set of included widgets is not enough, developers can continue coding with Java on the client-side using GWT."
