Sun Microsystems has open-sourced its Java toolkit for building mobile applications under the "GPLv2 with Classpath Exception" license.The lightweight UI toolkit (LWUIT) is an advanced UI library enabling rapid development of mobile applications that run across Java ME enabled devices, according to Sun's blog. The toolkit includes a range of graphical components, along with support for fonts, themes, animation and transition effects using Java Specification Request (JSR) 226.
Sun's move comes as the space for open-source mobile apps heats up. Last week, for example, open-source mobile consortium LiMo Foundation announced 11 new members and a handful of new devices. Google is also a competitor with its Android platform, which will power its forthcoming smartphone.CNET, The Register
