I've often mentioned the importance of programmers and graphics designers working together to create great looking RIAs. The declarative syntax of JavaFX facilitates this approach, and the "Project Nile" tool available with the JavaFX SDK makes this even easier.
If you are wondering what practical steps you can take to leverage this seismic shift, here are a few that I would suggest:
If you are currently designing an internet application or remodeling an existing one:
Think about how the full power of a rich client Java UI could improve the user experience.
Engage a graphics designer to create comps of this experience, reminding him/her that UI limitations imposed by the browser are history.
Define an interface to the application/business logic layer. Because JavaFX can instantiate and use Java classes, any interface that is implemented in Java can be used. I often use a simple HTTP-based interface that uses GET parameters to pass arguments, and returns a stream of data articulated in the JSON protocol. This approach will work well with JavaFX on all platforms (e.g. desktop and mobile phones).
Although Swing components are available in JavaFX, there is a strong trend in JavaFX as well as in RIAs (rich internet applications) toward graphical-node-centric UIs. Users are beginning to expect (and deserve) iPhone-style applications, so think less about Swing and more about Java 2D capabilities.
Because the JavaFX SDK will be a 1.0 release, there is a good chance that you'll want to create some of your own higher level custom controls. The JFX Custom Nodes category of this blog explains how to do this, and offers a few custom nodes that you might want to use. Also, Stephen Chin and Keith Combs, mentioned in the You Say You Want a (RIA) Revolution? post, have said that they will create custom nodes for use in JavaFX applications to augment what is released in JavaFX SDK 1.0.
And, of course, join me in downloading the JavaFX SDK 1.0 release from JavaFX.com on December 4.
By the way, my first speaking engagement after this release will be at Jfokus in Stockholm, Sweden. I'm going to do a 3.5 hour university session as well as a conference session. If you're in the area, please do attend!
