The Blackberry IDE puts the project files into e.g. :
C:\Program Files\Research In Motion\BlackBerry JDE 4.0.2\simulator
There will be .cod, .cso, .debug and .jar files for each project.
To run the simulator standalone, ensure that the project’s files are in the above directory, cd to the directory and then run the “type”.bat file in a command prompt.
e.g. to run the 7100v simulator, run 7100v.bat
