Distribute an application for testing
The BlackBerry® Java® Development Environment includes a command line tool called the JavaLoader tool that is located in the BIN folder in the BlackBerry JDE folder. You can use the JavaLoader tool to quickly install and remove compiled application files on the BlackBerry device directly over the USB port. You do not require any descriptor files or web pages. The JavaLoader tool can be useful when you install and remove your application frequently during testing and development; however, the JavaLoader tool is not designed for use by BlackBerry device users.
