JavaFX Jar doesnt run properly

Question

I edited this question, because I have used a different approach.

When running my JavaFX Application on my RasperryPi (with JDK8) with the following command: sudo java -Djavafx.platform=eglfb -cp ch.seerow.fotomat.app-1.0-SNAPSHOT-jfx.jar com.javafx.main.Main

I get the following error:

Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

I don't think that I'm using any AWT or Swing stuff, so I have no idea where this is comming from.

I'm using Maven to build my project, I use the following dependecies:

For the ImageJ dependency I used the following solution to get rid of the AWT and Swing stuff (http://imagej.1557.x6.nabble.com/Headless-ImageJ-td3699125.html). But I'm not sure if any other of my dependencies use AWT or SWING.

Thanks for any suggestions.

Answer 1

before running your app java fx :

export DISPLAY=:0.0

or in ssh :

setenv DISPLAY :0.0

Answer 2

I don't know what would be causing this since I don't work with JavaFX, but I found a simple tutorial on how to get it running on the Pi.

Besides, why do you use JDK8 instead of using 7? Many devices don't support the latest version yet.

• user1949422: I use JDk1.8 because this is the only one that supports JavaFX on the raspberry Pi.
