Sun's J2ME Wireless Toolkit is meant for developing Java applications that run on cell phones, PDAs, and other small mobile devices running Linux or another embedded OS for which a Java2 Micro Edition (J2ME) virtual machine is available. The toolkit includes an emulator, build tools, utilities, sample applications, and documentation.

New features in the 2.2 version beta include:

• Improved emulator — The DefaultColorPhone emulator skin now supports QVGA (320 x 240) resolution, with 4,096 colors instead of 256.
• Enhanced Mobile 3D graphics — New support for the Mobile 3D Graphics API for J2ME (M3G), including “immediate mode” and “scene graph mode” APIs.
• Multimedia Messaging — New support for the WMA 2.0 (JSR 205) API brings a Multimedia Messaging API. Support for JSR 120, version 1.1 of the Wireless Messaging API (WMA), remains.
• Bluetooth and OBEX — A new Bluetooth API compliant with JSR 82 includes an interface to Bluetooth wireless networking — including device discovery, and data exchange — as well as the Object Exchange (OBEX) API.
• Local files and personal information — New file management and Personal Information Management (PIM) APIs support JSR 75.

The beta release is available for download from Sun now. It requires a host machine running Windows XP.
