Using BlackBerry Messenger with a BlackBerry Application
You can integrate a BlackBerry® Java® Application with the BlackBerry® Messenger application. This could be useful if you are creating a turn-based game application for the BlackBerry device.
To create a BlackBerry Java Application that integrates with the BlackBerry Messenger application, you can use the classes in the net.rim.blackberry.api.blackberrymessenger package. For more information about using the BlackBerryMessenger class, see the BlackBerry API Reference .
