webservice ssl

Hello All-

I'm trying to configure a webservice to work over https w/o any luck. The web server has ssl installed and the server housing the webservice also has ssl installed. I configured the directory containing the webservice to require ssl, then tried to update the webservice registration in CF Admin and it failed. I am able to view the wsdl via https. I guess my question is, what is required to make a webservice run over ssl? It appears that simply requiring 128-bit encryption on the directory containing the webservice does not work.

TIA,

Aaron
