Developing BlackBerry Java Applications for
BlackBerry devices
Application developers can use the BlackBerry Java Development Environment or the for Eclipse to create and test
BlackBerry Java Applications for BlackBerry devices, and to package BlackBerry Java Applications to install them on
BlackBerry devices using a user’s computer or over the wireless network. Application developers can use the BlackBerry
JDE or the BlackBerry Java Plug-in for Eclipse to generate .cod files that contain the compiled application code for a
BlackBerry Java Application. BlackBerry devices execute .cod files to run BlackBerry Java Applications. The BlackBerry
JDE and the BlackBerry Java Plug-in for Eclipse also include tools to generate .jad files or .alx descriptor files that provide
information about a BlackBerry Java Application that is used when the application is compiled.
MIDlets are Java applications that conform to the MIDP standard and can run on any mobile device that runs Java
applications. Most MIDlets are distributed as .jar files. The BlackBerry JDE and the BlackBerry Java Plug-in for Eclipse
include tools that you can use to convert existing MIDlets that are in .jad and .jar file formats to .cod file formats for use on
BlackBerry devices.

Preparing to distribute BlackBerry Java
Applications
To send a BlackBerry Java Application to BlackBerry devices, the application developer must create a .zip file that contains
the necessary application files and an .alx file that contains information about the application. If a directory structure is
described in the .alx file, that directory structure must be represented in the .zip file.

Before you distribute BlackBerry Java Applications, you must specify a shared network folder for BlackBerry Java
Applications using the BlackBerry Administration Service. This shared network folder must not be the same network share
location that is used for BlackBerry Device Software, and it must not be located in
<drive>
:\Program Files\Common Files
\Research In Motion . The BlackBerry Administration Service accesses the shared network folder to install BlackBerry Java
