Introduction

This book describes how to use the J2ME Wireless Toolkit.

The J2ME Wireless Toolkit is a set of tools that makes it possible to create applications for mobile phones and other wireless devices. Although it is based on the Mobile Information Device Profile (MIDP) 2.0, the J2ME Wireless Toolkit also supports a handful of optional packages, making it a widely capable development toolkit.

1.1Quick Start

If you’d like to get started right away, try the demonstration applications that are included with the J2ME Wireless Toolkit.

To run the demonstrations, start KToolbar. On Windows you’ll do this by choosing Start > Programs > J2ME Wireless Toolkit 2.2 > KToolbar.1 You’ll see a window like this:

1.Depending on how Windows is configured, you might need to choose Start > All Programs instead of Start > Programs.
