B4J Question java.lang.NoClassDefFoundError: javafx/embed/swing/SwingFXUtils

[Angelo Messina]

Hi, I have to run an app that I wrote with B4J which works great in Windows 11 but as soon as I run the .jar on the iMac I get this error only when I select the option to save an image to a .png file via img.WriteToStreamm( out,100, "PNG")
compiled with jdk.14.0.1 and run with javafx 22.0.1

main._imagetobytes (java line: 382)
