About the BlackBerry JDE

The BlackBerry® Java® Development Environment is a fully integrated development environment and

simulation tool for building Java 2 Platform, Micro Edition applications for Java-based BlackBerry® devices.

It is a Mobile Information Device Profile (MIDP) compliant J2ME™ environment for developers who wish to

maintain seamless portability in their wireless applications.

Use the BlackBerry JDE to build applications that take advantage of the unique features of the BlackBerry

device, such as desktop synchronization applications, GPS applications, and applications that push content

proactively to BlackBerry devices in environments that use the BlackBerry Enterprise Server. The

BlackBerry JDE provides ways for BlackBerry device applications to establish network connections to

servers on the Internet or the corporate intranet.

Each version of the BlackBerry JDE comes with the BlackBerry Smartphone Simulators that were available

when that version of the BlackBerry JDE was made public. You can download additional BlackBerry

Smartphone Simulators from the BlackBerry Developer Zone web site:

http://www.blackberry.com/developers/index.shtml.

Getting started with the BlackBerry JDE

You can start the BlackBerry® Java Development Environment in one of two ways:

1. From the Start menu, select:

Programs > Research In Motion > BlackBerry JDE 4.7.0 > JDE

2. Invoke ide.bat, located in the bin subdirectory of the BlackBerry JDE installation directory.

Internationalization

The BlackBerry® Java Development Environment contains tools that assist with internationalization (i18n)

efforts. It is important to follow naming conventions.

Note: The .rrc and .rrh files must exist in the same directory for successful compilation.

Note: You should define resource keys in uppercase letters only.

See the BlackBerry Java Development Environment Development Guide or the BlackBerry Integrated

Development Environment Online Help for more information about localization.

Code samples

A sample BlackBerry® JDE workspace exists in the samples subdirectory of the BlackBerry JDE installation

directory. It contains sample programs that demonstrate how to design and build Java applications for

BlackBerry devices
