Material file won't load when an Object file is loaded

So I've been trying to play around with Java 3D and, recently, I've been playing around with importing outside 3D models into a program. At this point, I can get the model into the program as an OBJ file, but for whatever reason, the program won't load the corresponding material file and I don't know if the problem is my coding or if the file just wasn't exported properly.

This is the code I wrote:

import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.geometry.*;
import javax.media.j3d.*;
import com.sun.j3d.loaders.objectfile.*;
import com.sun.j3d.loaders.Scene;
import java.awt.Color;
import javax.vecmath.*;

public class ModelLoadingTest {

    public static void main(String[] args) {
        SimpleUniverse universe = new SimpleUniverse();
        BranchGroup scene = new BranchGroup();

        ObjectFile loader = new ObjectFile(ObjectFile.LOAD_ALL);
        loader.setFlags(ObjectFile.RESIZE);

        Scene modelScene = null;

        try{
            modelScene = loader.load("paintedcar.obj");

        }
        catch(Exception e){

        }

        DirectionalLight lighting = new DirectionalLight(new Color3f(Color.WHITE), new Vector3f(0f, 0f, -1f));
        lighting.setInfluencingBounds(new BoundingSphere(new Point3d(0.0, 0.0, 1.0), 100));

        scene.addChild(modelScene.getSceneGroup());
        scene.addChild(lighting);
        universe.addBranchGraph(scene);
        universe.getViewingPlatform().setNominalViewingTransform();
    }
}

If it helps, the models I'm testing with were made in Maya and exported as Wavefront files.

... You are not loading the texture what so ever in your code. The matirl file is not coded in a obj file, you need to import it as a texture, You can do this the same as you would for a sphere except when you assign the texture to the mesh. When you assign it you need to use 

"mesh name".setAppearance("your Appearance name");

for example

model.setAppearance(ap);
