JavaOne: Sun opens Looking Glass, sees more Java clients

IDG News Service - Sun Microsystems Inc. is releasing the source code for a user interface technology that provides users with a 3-D view of their PC desktop, part of an effort to drive greater use of Java on PCs and other client devices.

"The client is back," said Jonathan Schwartz, Sun's president and chief operating officer, in a speech at the start of the JavaOne show in San Francisco Monday. He also previewed an upcoming version of Java 2 Standard Edition (J2SE), the desktop version of the Java standard.

Called Project Looking Glass, Sun's interface technology was first shown a year ago. It should allow developers to build desktop user interfaces that are easier and more intuitive to use than traditional desktop windows, Schwartz said.

With Looking Glass, application windows are translucent and appear to hover on the screen. Users can stack, rotate and flip the windows in whichever way makes it easier to find and view information. Enamored with the technology's gee-whiz factor, Sun plans to show it off on giant screens on street corners around San Francisco this week.

Looking Glass is for computers running Linux and Sun's own Solaris operating system. By offering the code under an open-source license, Sun hopes to draw the attention of more developers, who it hopes will use the technology and improve it further. It plans to release a Looking Glass software developer kit in the coming months, officials here said.

Looking Glass is little more than a good-looking technology at the moment, but its release to the open-source community could see it used in some interesting applications that could spur adoption, said James Governor, principal analyst at Red Monk in Bath, Maine. And because the technology is open-source, developers might be able to create a version for Windows, he said.

IBM and BEA Systems Inc. have also been promoting new desktop platforms recently, Governor noted -- IBM with a project based on Eclipse, and BEA with an effort called Alchemy that aims to make the Web browser more useful by adding better caching and synchronization technologies.

"Schwartz said the client is back, but in fact the rich client is back," Governor said. The industry seems to be recognizing that Web portals, or personalized Web sites with multiple content windows, aren't the easiest way to navigate through information, especially for consumers, he said.

Schwartz also highlighted the upcoming release of a new version of the Java standard for desktop applications. J2SE Version 5 is being targeted for release on Sept. 30 and should provide better
