"Oracle said it would donate a set of Ajax-enabled user-interface components in the next few months. The Redwood Shores, Calif., database company said developers would be able to assemble the reusable components on a page and connect them to an application data source. The company has integrated Ajax with JavaServer Faces technology to build highly interactive user interfaces that run 100 percent within a browser with no downloads, officials said." (TechWeb)
This is not a big announcement, but it does support Oracle's recent focus on open source. From my perspective, open sourcing existing technology is a better open source strategy for Oracle than the acquisition strategy that it has been rumored to have been pursuing.
