BlackBerry® Java® Development Environment (BlackBerry JDE)
The BlackBerry Signature Tool contains a command line version. Running the BlackBerry Signature Tool directly from the command line allows you to add extra parameters to speed up the signing process if desired. In BlackBerry JDE 4.3 and later you can add the -p <password> flag (along with -a -C) to completely automate the processes. For security reasons, this is not recommended.
