Open Possibilities

An Interview with JCP Chair Onno Kluyt from JavaOne 2007

This year's JavaOne slogan was "Open Possibilities." Artima asked Sun's JCP Chair Onno Kluyt to tell us about new possibilities that some Java developers may find surprising. In this interview, Kluyt describes three Java technologies that allow developers to build new kinds of applications.

As Chair of the JCP, Onno Kluyt gets to have an early look at most new Java technologies, certainly those that wind their way through the Java standardization process. We thought that Kluyt might be a good person to ask to help make this year's JavaOne slogan, Open Possibilities, a bit more concrete.

In this brief interview, Kluyt shares three technologies that he thought could hold new promises to Java developers. While each technology has been around for many years, only in the past year did each mature to the point where each is of interest to almost any Java developer:

If you had a real-time JRE, what would you do with it? A mainstream, runtime environment with real-time capabilities?... What if you had that available in a Java EE application server, or in your runtime environment on the desktop? What kinds of things would you go and build for that?

What if you had the same very rich API, things like Swing and Java 2D, not just on the desktop, but also on the TV set-top box, or on your ... mobile phone? What kind of applications would you build [to take advantage of that]?

We showed during one of the keynotes ... Project Iris. It [lets you] drag and drop pictures into your Web page... And you can edit those pictures, because now you have an applet there, integrated into your browser, and you get full access to Java 2D, and other graphical APIs. Because manipulation [of the images] does not involve round-trips to the server, you can provide a much faster and richer environment...

What do you think are some of the biggest "hidden" opportunities in Java today?
