JavaFX 3D InvocationTargetError when applied texture

Question

I am trying to make a 3D game in java. So I decided to add a class to each material needed so I started with wood. when I added diffuseMap I got InvocationTargetError. Why did this happen? Here is the Wood.java code

Edit: Changing to url or other ways did not work


package com.front.fire.graphics.shapes.Cuboid;

import javafx.scene.image.Image;
import javafx.scene.paint.Color;
import javafx.scene.paint.PhongMaterial;
import javafx.scene.shape.Box;

public class Wood extends Box {
    public Wood () {
        super();

        PhongMaterial mat = new PhongMaterial(Color.LIME);
        mat.setDiffuseMap(new Image("Path to texture"));
        this.setMaterial(mat);

    }
}

Edit: I added the error track Can someone please find solution for this

Thank you

The `Image` constructor expects a URL (or at least a _resource_ path), but you're likely passing it a file path (e.g. `C:\Users\....`). So it thinks the drive letter is the URL scheme, but that scheme is not known. That said, your image should probably be a resource anyway; check out [How do I determine the correct path for FXML files, CSS files, Images, and other resources needed by my JavaFX Application?](https://stackoverflow.com/questions/61531317/how-do-i-determine-the-correct-path-for-fxml-files-css-files-images-and-other). — Slaw, Sep 24 '21 at 05:24
What is the actual value for "Path to texture"? You should be able to find it using `new Image(Wood.class.getResource("texture.png").toExternalForm())`. For that to work, ensure that “texture.png” is in the same location as `Wood.class` before you run your app. — jewelsea, Sep 24 '21 at 06:48
You tried all suggested approaches and troubleshooting recommendations from the comments and the duplicate, and for every single one you receive an error which says, “unknown protocol: c”? That seems quite strange, at minimum I think there would be a different cause for the exception when different approaches are used. Try using a http url to retrieve an image off the web and see if that works for you at least it should give you a different error. — jewelsea, Sep 24 '21 at 08:53
