How to dynamically load Nodes?

Question

Hi,
is it possible to dynamically (discovered at runtime) load subclasses of CustomeNode and at instances of these to the scene?
I'm trying to implement a GUI that displays data from third-parties. The idea is that third-party modules provide their own Node to be embedded into the main GUI.
regards
robert

It should be possible to do using URLClassLoader.
For example:
import java.net.URL;
import java.net.URLClassLoader;
import javafx.scene.Node;
import javafx.stage.Stage;
import javafx.scene.Scene;
var url = new URL("file:/C:/Temp/JavaFXApplication25/dist/JavaFXApplication25.jar");
var classLoader = new URLClassLoader([ url ]);
var cls = classLoader.loadClass("pack.UserNode");
var node = cls.newInstance() as Node;
Stage {
    title: "Application title"
    scene: Scene {
        width: 250
        height: 80
        content: [ node ]
}
