I've followed the Method #2: Signing Application Using a Command Line in the GEtting Started RPI MEEPG https://docs.oracle.com/javame/8.3/get-started-rpi/MEEPG.pdf
All works fine until the jadtool -addjarsig stage. It returne me a java.security.UnrecoverableKeyException: Cannot recover key
What is the problem I don't understand, should I use the same key from the same kestore of the previous -addcert stage ? It's what I've done. It's particulary bad explained (and there is a text failure in the command parameter importjakfile unless importjadfile)
I use Java_ME_platform_SDK_8.3 on debian linux and rapsberry 3 with 8.3 embedded API.
thanks for all
