Problem in loading multiple textures

Question

hi guys
i need some help form you in loading *.obj files into my scene. when i load a building into my scene only the white building is loading without any textures. when i tried to load a texture for eg: green...the whole building is in green color. i have some *.mtl files in the same folder but i dont know how to use them.
here is code :
ObjectFile file1 = new ObjectFile (ObjectFile.RESIZE);
          Scene scene1 = null;
          Scene scene2 = null;
          scene2 = file1.load("model/street lamps/Lamp_Post_Ornate.OBJ");
          tg_lamp.addChild(scene2.getSceneGroup());
          Appearance appear_lamp=new Appearance();
          TextureLoader loader_lamp = new TextureLoader("texture/building.png", this);
          appear_lamp.setTexture(loader_lamp.getTexture());
          BranchGroup branchGroup1 = scene2.getSceneGroup();
             shape = (Shape3D) branchGroup1.getChild(0);
              shape.setAppearance(appear_lamp);
          obj_bg.addChild(tg_lamp);
