It looks like Java 8 with Swing runs fine on the Raspberry Pi, even the least powerful version of the RPi:
Raspberry Pi Zero.
As I found out jfxswt.jar required to run JavaFX is not included in the JDK normally any more.
How would I find the folder to place it so that JavaFX can be run on the RPi?
( I got it downloaded as part of Gluon)
If this file is included can I also compile JavaFX on the RPi or just run it?
(Does it need to be compiled on a separate desktop computer?)
