What is it?
WebKit for SWT (ver. 0.5) is an embeddable Java™ WebKit browser component developed by Genuitec. This component can be used in the development of a wide range of Java SWT applications that require integration of rich HTML5, CSS3, JavaScript and Flash content and functionality.

WebKit for SWT is being developed to serve as a technology platform for our OSS mobile web initiative, Eclipse Blinki Mobile Web DevKit and in the research of a new generation of network-based developer tools.
