IWS and GSKit for HTTPS

Does anybody here have any experience configuring the IWS client and server to use HTTPS?

Obviously there's some configuring to do, because if I just use something like "https://foo.bar"; in the client endpoint, I end up with:

> AXIS EXCEPTION: (
> 23
> )
> HTTPTransportException: HTTPS transport error.
> GSKit Error is 202 - Key database file was not found.

And I can't make head or tail of what it says about this in the "IWS Web Services Client" book. (Not that I can make much sense of ANYTHING in that book.)
