Sun is looking to move JavaFX further into the open source world, according to a company executive. The company has already made some components of JavaFX, its technology for building RIAs (rich Internet applications), available under the GPLv2 open-source licence.
But the company is looking to move further. Other key components are still proprietary and Sun is now working to change this, said Jeet Kaul, vice president of the Client Software Group in a recent blog.
"There are some dependencies on licensed code that cannot be open sourced. We are working towards decoupling the dependencies so that the non-proprietary portions can be open sourced," Kaul wrote. "We will put the core runtime out in the open over time."
Kaul did not spell out the nature of the dependencies and Sun did not respond to a request for more information.
Sun will also publish specifications for new file formats associated with JavaFX, "shortly," Kaul said.
Kaul's blog post came in response to those questions and others posted by Java developer Osvaldo Pinali Doederlein.
The Sun executive also provided an updated road map for JavaFX, writing that the mobile platform - now in beta - will be released "by March" and a visual designer tool will be available in the middle of next year.
While JavaFX will compete with a range of other RIA toolsets, such as Adobe's AIR (Adobe Integrated Runtime) and Microsoft's Silverlight, Sun is banking that Java's pervasive market penetration will give it an edge.
