My Java s40 app for asha failed the QA test with the above title. I have tried recreating the problem by download the jar file to one of the supported asha phone and the app launched successfully. Every other things seems okay i have also used the Nokia RDA to test the app. What other reasons may be causing the failure.
Just from the Error message I can assume that the your Jar File's MIDP & CLDC version doesnt match with your S40 Asha series phone.
You need to open your editor/IDE and change to MIDP Version to 2.0 & CLDC's version to 1.1.
