Tabris is a cross-platform mobile framework for Java.
Tabris is a Java framework written by Java developers for Java developers to build mobile apps.
It uses standard JavaEE technology to create an application on a server. Native clients act as a player for the applications's UI. They access the application by calling a URL that provides a JSON representation of the UI. The clients will use this JSON message to render the UI using native components.
Native components are Cocoa Touch widgets in iOS, Java based widgets in Android and HTML5 in a browser.
