An early access download of the Java ME 3.0 SDK is now available for Windows XP and Vista from Sun Developer Network. Notable features include LWUIT integration, Blu-ray and Windows mobile support.

The Lightweight User Interface Toolkit or LWUIT, a project to enable J2ME developers to create consistent and easily usable mobile Java applications, has made its source code available under the GPL2 license. Previously a binary only download was provided by the project.
