Diffiuse Specular etc not loaded from obj file

[GoogleCodeExporter]

If i enable lightning on an obj without textures i dont see the colours. The 
colours are loaded but it doesnt work. I'm trying to make it work now and i 
think it has todo with the following code not being executed.... however it 
deosnt work yet. Maybe you now the solution?

// the approach is just a proof-of concept
// but it doesnt work

            FloatBuffer f = FloatBuffer.allocate(4);
            f.put(1f);
            f.put(0.4f);
            f.put(0.4f);
            f.put(1f);
            f.position(0);
            _gl.glMaterialfv(GL10.GL_FRONT, GL10.GL_DIFFUSE, f);
            f.position(0);
            _gl.glMaterialfv(GL10.GL_FRONT, GL10.GL_AMBIENT, f);
            f.position(0);
            _gl.glMaterialfv(GL10.GL_FRONT, GL10.GL_EMISSION, f);
            f.position(0);
            _gl.glMaterialfv(GL10.GL_FRONT, GL10.GL_SPECULAR, f);

            _gl.glMaterialf(GL10.GL_FRONT, GL10.GL_SHININESS, 15.0f);

I was wrong this is not it.
However what i did to make it work was:

if ($o.hasVertexColors() && $o.vertexColorsEnabled()) {
            $o.vertices().colors().buffer().position(0);
            _gl.glColorPointer(4, GL10.GL_UNSIGNED_BYTE, 0, $o.vertices().colors().buffer());
            _gl.glMaterialfv(GL10.GL_FRONT, GL10.GL_SPECULAR, $o.vertices().speculars().floatBuffer(null));
            _gl.glEnableClientState(GL10.GL_COLOR_ARRAY); 
        }
        else {
            _gl.glColor4f(
                (float)$o.defaultColor().r / 255f, 
                (float)$o.defaultColor().g / 255f, 
                (float)$o.defaultColor().b / 255f, 
                (float)$o.defaultColor().a / 255f
            );
            _gl.glDisableClientState(GL10.GL_COLOR_ARRAY);
        }

So now the specular is loaded. I also always enable material (not sure if its 
needed)

// Colormaterial
        _gl.glEnable(GL10.GL_COLOR_MATERIAL);
        /*
        _gl.glGetIntegerv(GL10.GL_COLOR_MATERIAL, _scratchIntBuffer);
        _scratchB = (_scratchIntBuffer.get(0) != 0);
        if ($o.colorMaterialEnabled() != _scratchB) {
            if ($o.colorMaterialEnabled())
                _gl.glEnable(GL10.GL_COLOR_MATERIAL);
            else
                _gl.glDisable(GL10.GL_COLOR_MATERIAL);
        }
        */

I met same trouble.
So please let me know how to make vertices().speculars().
It is not in trunk.

Thank you.

Please let me know how to make vertices().speculars() too...
Thanks.
