Can you post a copy of the SOAP message received? How is the client application sending the SOAP message? What kind of SOAP engine do you have on the server? What is generating the error message above? [ October 24, 2008: Message edited by: James Clark ]
It seems you wrote your server with WSE3. Do you have WSE3 clients which are working properly with this server? If not I suggest you would start with building such a client as it's easier to debug this way.
Also check that your client & server use the correct X.509 and that your server has permissions to the X.509 private key.
