Transform-> Morph -> Map to Surface. Also, when using Map to Surface, make sure your curve has plenty of control points or else it will be too "stiff" and not map correctly to the target surface. This might require you to rebuild the curve.

I didn't notice before I wasted my time on a reply that you first asked this question two years ago  - and now you are asking for help? What's the hurry?
