In 2000, Ruben Daniels and Rik Arends anticipated the browser would become the free platform for all.


Javeline PlatForm is an application development framework (also called a library, or toolkit) aimed at developers for building applications that run in web browsers, but look and feel like conventional desktop applications.

Because an RIA runs on the Web or an intranet, these type of applications are usually installed on a server: everybody always has the latest version.
