Load obj Model but Texture Bug

hello, i have a problem with an obj Model.

I’ve created a model in Blender with a texture. It is a field for a game.

When i load this in java, no problems appear. But instead showing the texture, the model have a brown color.

Here two screens for it.


scene with model:

And this is the relevant method:

protected void initGame() {
      scene = new Node("scene");
      pitch.fromAngleAxis(FastMath.PI / 2, new Vector3f(1,0,0));
      ObjToJme converter = new ObjToJme();
      try {
         URL objFile = Test.class.getClassLoader().getResource(
         converter.setProperty("mtllib", objFile);
            try {
                  new SimpleResourceLocator(Test.class.getClassLoader().getResource("data/")));
         } catch (URISyntaxException e) {
            // TODO Auto-generated catch block
         ByteArrayOutputStream BO = new ByteArrayOutputStream();
         System.out.println("Starting to convert .obj to .jme");
         converter.convert(objFile.openStream(), BO);
                        //load as a TriMesh if single object
         TriMesh model = (TriMesh) BinaryImporter.getInstance().load(
               new ByteArrayInputStream(BO.toByteArray()));

         model.setModelBound(new BoundingSphere());

      } catch (IOException e) {

       scene.updateGeometricState( 0, true );
