SOAP Method to consume Aperio DataServer webservice

Hi: Has anyone had any luck using the SOAP Method component to consume webservices from the Aperio DataServer? I supply the following parameters:

SOAP Endpoint: http://[hostname]:86/dataserver/Aperio.Images/Image.asmx

Method Name: GetImageData2

Method Namespace: http://[hostname]:86/webservices/

SOAP Action: http://[hostname]:86/webservices/GetImageData2

SOAP Parameter Names: UserName, PassWord, ImageId

Method Parameter Vaules: 'administrator', '********', 77

And I get the following response;

CompressedFileLocation
  -4046

ASMessage
  Failed to parse request.

Has anyone had any success with this?

Thanks,


Chris
