Infos

The open source JavaFX platform offers a Java-based approach to rich Internet application (RIA) development-an alternative to Adobe Flash/Flex and Microsoft Silverlight. At over 100 million downloads, JavaFX is poised to be a significant player.

Written by a JavaFX engineer and developer, this book is one of the first on the JavaFX platform to give you the following:

• The fundamentals of JavaFX scripting on desktop and mobile platforms
• Examples of RIAs using JavaFX Graphics
• Media and animation using JavaFX

See how JavaFX gives you dynamic Java effects in your RIA development.

A. Lawrence Prem Kumar has more than 5 years of experience in Java and J2EE. Since 2005, he's worked for Sun Microsystems. Presently, he is working on Java FX, focusing particularly on Java FX graphics.
