Hi, you need to convert your MIDlet first:
C:\Program Files (x86)\Research In Motion\BlackBerry JDE 4.6.0\bin>rapc import="C:\Program Files (x86)\Research In Motion\BlackBerry JDE 4.6.0\lib\net_rim_api.jar" codename="C:\BBMidlet" -midlet "C:\xxx.jad" "C:\xxx.jar"
You will get a file named "BBMidlet.cod" ... Then use the option "Load
Java Program" from BB Emulator
That's all
If you want to emulate networking operations, you need to install the "BlackBerry Email and MDS Services Simulators 4.1.2" as well.
