Type of files created in a blackberry project

I created my first Hello world project for BlackBerry and following files were created in the deliverables folder:

 - HelloWorld.cod
 - HelloWorld.cso
 - HellowWorld.debug
 - HelloWorld.jad
 - HelloWorld.jar 
 - HelloWorld.rapc

What is the purpose of each of these files? I know at least that the jar file must be deployed as a mobile application. But what about all other files?

Solution

  • The .cod file is basically BlackBerry's proprietary version of the .jar file. (This is usually the version downloaded from the App Store.)

    The .cso file is a helper file used when signing the application. (It says which keys are needed.)

    The .debug file is a helper file used when running the application in the debugger.

    The .jad file describes the application to help the device know if it's compatible. (If you were downloading onto a BlackBerry from a website instead of the App Store, this is the file you'd point your link at, which would contain the path to the cod/jar.)

    The .jar file is the main application file for MIDP, which is sort of a generalised mobile java runtime environment.

    The .rapc is a helper file used by the BlackBerry JDE when it's compiling/building the project.
