Why my md5 model is translucent?

but i try to my program the model is translucent

any one can tell me , i remove what cause translucent?

      //Time for a little optimization. We don't need to render back face triangles, so lets

        //not. This will give us a performance boost for very little effort.

I spend a lot of time

final i find the question

we add this

//        CullState cs = display.getRenderer().createCullState();

//        cs.setCullMode(CullState.CS_BACK);

//        scene.setRenderState(cs);
