I have installed the Jfilament plu-in from the website http://athena.physics.lehigh.edu/jfilament/download.chy and I have copied the folder in the plug-in folder of ImageJ. The Jfilament 2D is working, but
the 2Dplugin Inside Jfilamente folder are not working and it shows this error.
Also, the Jfilament 3D is not working, showing this error
Do you have any idea to let it work?
