Sun's biggest announcement at JavaOne 2007 was its renewed interest in the client and, specifically, a client-side framework the company dubbed JavaFX. Obligatory keynote demos notwithstanding, many conference attendees were buffled just what JavaFX meant. In this interview with Artima, Jacob Lehrbaum, Sun's client systems group product line manager, describes the mobile version of JavaFX, and provides the big picture of where JavaFX fits in with other client-side Java technologies.

Sun's renewed interest in client-side Java was welcomed by many JavaOne 2007 attendees. Just what that interest meant, however, was not clear to many, not the least because Sun decided to introduce a new technology, JavaFX, to further cloud the client-side landscape.

JavaFX was understood by many to be primarily a high-level scripting language based on Sun engineer Chris Oliver's Form Follows Function, or F3, language. JavaFX, however, is meant to be more than just a scripting language for the client. In his interview with Artima, Jacob Lehrbaum, Sun's product line manager for client-side Java, explains that JavaFX is a client-side layer above the regular Java APIs that allow the easy creation and deployment of media-rich Java applications.

Lehrbaum manages the mobile side of JavaFX, and in the interview talks about how JavaFX relates to APIs already available in Java ME for consumer-facing applications. While mobile Java standards, such as the Mobile Services Architecture (MSA), JSRs 248 and 249, are important to provide a broad technology base that all mobile infrastructure providers can leverage, JavaFX is a Sun product that the company hopes to license to mobile phone makers and even to set-top box manufacturers.

JavaFX Mobile's main value is that it provides an integrated stack that developers can rely on for various pieces of a mobile application, such as accessing Web services and displaying multimedia. The mobile JavaFX stack will pick up where the various Java ME JSRs left off, and fill important wholes in mobile Java, such as providing multimedia codecs.
