JavaFX Application not launching

Support Software & Applications
1

I installed a JavaFX application and tried to run it with java -jar but it does not run and shows this error message:
image

archlinux-java status output:

11:57:47 [legacy@LegionY520] ~ /> archlinux-java status
Available Java environments:
  java-8-openjdk/jre (default)

The JavaFX Oracle page states that JavaFX comes with all JDK/JRE installations since version 7u6.

Any help would be appreciated.

I’m sorry, I’m not particularly experienced with the topic at hand.

What do I have to run to install JavaFX?

Sorry,
Install your corresponding javafx package … in your case it seems to be version 8 … so

sudo pacman -S java8-openjfx

It works! Thanks for the quick reply!
