I have got this problem as well. From what I can find out it is caused by the types, possibly the request and response in John's wsdl. My wsdl is from a 3rd party application so I can't change it much, but I would like to know what I can do to fix it.
I have included the WSDL & XSD docs below

General Information
Perceptive Software's ImageNow(TM) product provides document imaging and management functionality including a document-centric workflow implementation. Perceptive Software's Message Agent exposes a subset of this functionality as web services.
This WSDL defines the basic access (authentication/authorization) web services available for use in Message Agent client programs.
