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.
