jMaki is a client/server framework to ease development of Ajax applications, and it abstracts much of the javascript and CSS needed while covering several javascript libraries as Yahoo's YUI, Dojo and Scriptaculous. jMaki is made of both client side components (layout, client services and runtime as well as a widget model) and server side components ( server runtime and XmlHttpProxy).

Quickstart guides are available for Java and PHP, but efforts are also underway to make it available in Ruby on Rails

Version 1.0 of jMaki is now available for download.
