JavaFX is not supported on the Raspberry Pi. It's probably not supported for the Nano Pi, either. That means you should only write Non-UI programs for them.

Hi.. thanks for your reply.. but i think my code is a non-ui program :O
This is example from Erel's

These are different errors.

It seems like you are running multiple instances of B4J-Bridge. Only run it once.

Also make sure to run it with sudo java -jar b4j-bridge.jar

i already try but like that erel

Erel · Jul 31, 2017

My guess is that there are multiple instances of B4J-Bridge running.

Restart the board and try again. If it still happens then start it with:

sudo java -jar b4j-bridge.jar -disableftp
