An operation can have only one in or out header of a given type?

Situation: I am trying to consume a clients web service for CC authorization. They are not publishing the WSDL file on there site, but they have provided the WSDL file. I am using Visual Studio 2005 and c开发者_运维问答reating a web application that consumes the web service.

The only reference to this error that seems to apply is here: http://followtheheard.blogspot.com/2007/12/consuming-web-services.html. I installed WSE3.0 and configured my project to use WSE and am calling the WSE version of the web reference and I am still getting this error. Any help would be appreciated.

Apparently there is poor interoperability between web services written in Java requiring WSE and Visual Studio 2005. Upgrading to Visual Studio 2008 allows for easier use of the WSE3.0 toolset.
