This article applies to the following:


  • BlackBerry® Java® Development Environment (BlackBerry JDE)
  • BlackBerry JDE Component Pack
  • BlackBerry devices based on Java technology
  • BlackBerry Java SDK



When creating and building your application, it is important to choose the correct version of the BlackBerry® Java® SDK or BlackBerry JDE to make sure that the application is compatible with the target BlackBerry devices. Applications built in the BlackBerry Java SDK or BlackBerry JDE are forward-compatible with later BlackBerry® Device Software versions, but they are not backward-compatible with ealier versions.


For example, an application built in BlackBerry JDE 4.1 runs on a BlackBerry devices running BlackBerry Device Software 4.1 and later will not run on a BlackBerry device running BlackBerry Device Software 4.0. Thus, when building applications, you should use a BlackBerry JDE version that matches the lowest version of BlackBerry Device Software you want to support.


Note: To verify the version of BlackBerry Device Software installed on the BlackBerry smartphone, select Options > About.
