Sun officially enters the Rich Internet Application market with the released JavaFX. InternetNews.com covers the releaase at http://www.internetnews.com/dev-news/article.php/3788836/JavaFX+Finally+Makes+Its+Debut.htm
Time will tell if JavaFX can compete effectively with Microsoft's Silverlight and Adobe's Flash/Flex solutions. InternetNews reports that Sun's target audience for the JavaFX tool is "creators" but that JavaFX's target market extends to designers. When Microsoft released Blend and Silverlight, I believed that they had a large chasm to cross to get to designers. Getting designers to consider Java, a technology perceived to be more technical, seems to be an even wider gap to cross. But then, Microsoft seems to be making inroads with Silverlight, so maybe there is a chance for JavaFX to make the leap too.
You can find more on JavaFX at http://www.javafx.com/. You can also get the downloads from that site.
As an interesting side comment - the graphic on the JavaFX home page seems very similar to the type of marketing Microsoft is doing with Windows....
