Sun and Oracle have been very quiet about the plans for Sun's various and diverse technologies once Oracle's acquisition becomes final later this summer. In a surprise move, Larry Ellison of Oracle appeared onstage at JavaOne this past Tuesday (June 2nd) with Sun Chairman Scott McNealy (after Jonathan Schwartz had left the stage). Larry let lose a number of insights on where he may be headed with Sun's technology portfolio. I recommend that interested viewers take a look at the last part of the 2009 JavaOne opening keynote session.
One of the specific initiatives that Larry mentioned was that Oracle/Sun will port OpenOffice to JavaFX, the new Java scripting language. Now many commentators are dissecting the import of this initiative (take a look at what Gavin Clarke had to say for The Register). Many think it is an unsound effort, but I believe that they are missing the point.
My guess at why Larry wants to port OpenOffice to JavaFX is so he can deliver it as an application service through the cloud. This is an inadvertent shot at Microsoft Office and a direct challenge to Google apps.
That's just my opinion. As an FYI, Sun spent some time during the CommunityOne conference (also held at the SF Moscone Center and just prior to JavaOne) talking about its latest cloud initiative and Sun's monster cloud at the SuperNAP data center in Las Vegas.
