GridFX on Raspberry Pi & JavaFX 8



For my first JFX demo I tried to create a experimental [GridFX]({{ site.baseurl }}{% link pages/projects/ %}) version for JavaFX 8. As I mentioned in an earlier post there are some API changed between JavaFX 2 and 8. For GridFX I had to change two things:

  • The BaseSkin class is now public
  • The CSS support that I used in GridFX seams to work completely different in JavaFX 8.

Both issues were fixed very fast and an GridFX demo was running on my Mac where I have JDK “build 1.8.0-ea-b69” installed (download it here). But after deploying the demo on my Pi nothing happened…

So I created a log file for the java output by adding some parameters to the shell command:

java -cp myApp.jar com.guigarage.Demo >log 2>&1

The logging showed me the cause of my problems:

java.lang.NoSuchMethodError: javafx.scene.control.SkinBase.(Ljavafx/scene/control/Control;)V at

While everything compiled perfectly on my Mac, the Pi has a different JavaFX compilation / version (“build 1.8.0-ea-b36e”). As a first solution I downloaded the “jfxrt.jar” file from my Pi and included it to the GridFX project on my Mac. After doing so I saw all the compilation problems in Eclipse and had a change to resolve them. It would be very nice to have a real 1.8.0-ea-b36 build installed on my Mac. Any idea where to get it?

But after fixing all this problems the GridFX demo is running on my Pi:
