.JDP File Extension

A JDP file is a project created by BlackBerry Java Development Environment (JDE) and the BlackBerry JDE plug-in for Eclipse, which are used to create and test Java apps for BlackBerry smartphones. It contains information on how JDE should build the BlackBerry application including the resource files needed for the build. JDP files also contain project properties, such as the application type.

When you create a project in BlackBerry JDE, a JDP file is created to store the contents. To create a JDP file you must first create a new workspace by selecting File → New Workspace. You can then create a new project by selecting Project → Create New Project.

NOTE: When a JDP project is compiled, the source files are compiled into a .COD file.
