This example
shows how code is presented in the remainder of the book. Because
Bluetooth technology is a wireless radio technology, developing applications
requires hardware or a simulator. To enable readers to try out the
code in this book, the following section also describes how to set up a
development environment that makes it possible to build and test
JABWT code in a simulated environment.
3.3.1 Development Tools
Developing and testing JavaME applications, especially testing on a device,
can be a complicated process.Device testing is complicated due to a general
lack of debug tools and the effort it takes to download and install an
application. Therefore device simulators have been developed to allow
developers to create and debug applications on a desktop computer before
testing them on a device. A common tool for Java ME development is the
Sun Java Wireless Toolkit available at java.sun.com/javame. The Wireless
Toolkit provides software emulation of devices that support a variety of
Java ME speci?¬?cations. The Wireless Toolkit also provides support for
building, packaging, and testing Java MIDlets. (Support for JSR-82 is now
44 Chapter Three: High-Level Architecture
available in the Wireless Toolkit, but will not be used to test or demo the
code in this book.)
Another tool used in this book is the Motorola Java ME SDK for
Motorola OS Products.
