Creating Java ME applications is best done through one of the development tools that are freely available. The applications in this book have been developed on Sprint Wireless Toolkit 3.3.2 (referred to as SWTK from now on), and I would suggest that you install this toolkit on your computer. I chose the SWTK because, at the time of writing, this was the toolkit that LWUIT worked very well with—even better than with the Sun Java Wireless Toolkit 2.5 for CLDC.
The Java ME platform SDK had just been announced, but it was still evolving at the time of writing. Another attractive feature was the fairly wide variety of real life device emulators to run the applications.
The SWTK is a free download from:
