Hello.
Your help is very much appreciated.
I keep on getting the error "

"An unhandled exception of type 'System.InvalidOperationException' occurred in system.web.services.dll

Additional information: Path property must be set before calling the Send method"

Whenever I try to call a method on the web service.

I'm a newbie in web services.
Would you know what might be the cause of the error?

p.s.
I am using x.509 certificate with WSE 2

Thank you
Roy
