When you package a BlackBerry® application project, you create the files that you install on a BlackBerry device (for example .cod files and .alx files). When you package a BlackBerry application project, you trigger an incremental Java® build, and you also repackage the applications that depend on the BlackBerry application project. If your application uses protected BlackBerry APIs, you can invoke the BlackBerry® Signature Tool automatically after packaging.

For more information about the output files that are created when you package your application, see Packaging output for BlackBerry application projects
