Sun releases JavaFX Mobile

February 12, 2009 —  Sun Microsystems has made available a mobile development platform for creating rich Internet applications (RIAs) and other rich content.

JavaFX Mobile, announced today, is built on a Java ME (Micro Edition) platform implementation and, in most cases, has the same features as the desktop version of JavaFX. Jacob Lehrbaum, a senior product line manager at Sun, said that JavaFX Mobile has the same APIs, code and functionality as its desktop brethren

“The great thing about this is, for developers that have already been looking at JavaFX on the desktop, the mobile phone is now opening up to them because they don’t have to learn a new mobile-specific way of creating content,” Lehrbaum said.

Developers can use existing Java ME mobile applications and capabilities with JavaFX Mobile. They have access to Java ME’s file systems, address books, Bluetooth, camera, and location sensors. Additionally, developers can use existing Java libraries in JavaFX Mobile applications.

Jim Weaver, a senior vice president of technology for digital media provider Veriana Networks and author of his own JavaFX blog, praised JavaFX Mobile’s ability to run as an applet in the browser, on the desktop and on mobile phones. “This makes it easier to support various phones with the same applications, because JavaFX Mobile runs on top of Java ME, which is very prevalent on phones today,” Weaver said.

“Not only does JavaFX have UI capabilities, it also has a communication API that is common to all platforms, which makes it very conducive to running enterprise applications from mobile phones."

JavaFX, which was made generally available in early December 2008, offers audio, video, rich text, vector graphics, animation and Web services for mobile and desktop applications through what Lehrbaum called a very simple scripting language.

“As opposed to Java where you build things out programmatically and from the ground up, JavaFX has a lot of predefined behaviors and a default way to do animation,” Lehrbaum said. “If you want to do layout, there are better ways of doing that in JavaFX, which is much more similar to how people have been creating content for the Web.”

JavaFX Mobile is available on more than 2.6 billion mobile phones, the company claimed. Developers can build JavaFX applications on mobile devices by downloading the JavaFX SDK at www.javafx.com.

Sun executives said that several leading handset manufacturers, service providers and ISVs are working with Sun to ship JavaFX Mobile handsets. Among those companies are Sony Ericsson and RIA providers Cynergy Systems, EffectiveUI, and Nexaweb.

Sun is to premiere JavaFX Mobile next week at Mobile World Congress in Barcelona, Spain from Feb. 16–19.
