Sun Java Wireless Toolkit

The Sun Java Wireless Toolkit (WTK; formerly known as Java 2 Platform, Micro Edition (JavaME) Wireless Toolkit) is a toolbox for developing wireless applications that are based on JavaME's Connected Limited Device Configuration (CLDC) and Mobile Information Device Profile (MIDP), and designed to run on cell phones, personal digital assistants, and other small mobile devices. The toolkit includes the emulation environments, performance optimization and tuning features, documentation, and examples.

The J2ME Wireless Toolkit is a comprehensive set of tools for building MIDP applications. The toolkit can be used standalone, or incorporated into many popular integrated development environments (IDEs).

The project was founded and led by Dov Zandman from the Sun Microsystems team in Sun Israel Development Center in the year 2000. The developers of the first version were Daniel Blaukopf, in charge of the internals and Amir Uval on the User Interface.

Sun Java Wireless Toolkit 2.5.2_01 is the latest edition, but has been incorporated into the newer Java ME SDK 3.0. It integrates CLDC, CDC, and Blu-ray Disc Java (BD-J) technology into one SDK, and replaces Java Wireless Toolkit 2.5.2 and Java Toolkit 1.0 for CDC.
