CHAPTER

Developing MIDlet Suites
This chapter describes how you can use the J2ME Wireless Toolkit to create
applications. It begins with a description of toolkit projects, then works through the
development process.
There are two basic development cycles you are likely to follow in creating MIDlet
suite applications. The first is quicker and simpler; you will probably use it in your
initial development. The second cycle is longer but allows for more comprehensive
and realistic testing.
Toward the end of the chapter you’ll read about how to use the J2ME Wireless
Toolkit with advanced development tools like an obfuscator and a debugger. A
final section briefly describes how to configure a web server to serve MIDP
applications.
2.1 About Projects
In the J2ME Wireless Toolkit, MIDlet suites are organized into projects, where the
end result of one project is one MIDlet suite. A project contains all of the files that
will be used to build a MIDlet suite, including Java source files, resource files, and
the MIDlet descriptor.
The J2ME Wireless Toolkit works on one project at a time. You can create a new
project or open an existing project.
In this chapter you will work with a very simple example project. As you read
about each step in the development cycles, you can work along in the toolkit.
To create a new project, first start KToolbar. On Windows, choose Start > Programs
> J2ME Wireless Toolkit 2.2 > KToolbar
.

You’ll see the KToolbar window.

> Programs .
