Trouble creating webservice with custom object

Question

I have a custom object class that I'm consuming in the SoapHeader of my webservice. This class is in a seperate file, but within the same namespace as the service. The class was derived from an xml schema. The object gets passed through the header and is processed by the "import()" webmethod. I can invoke this method manually with no problem -- however, when consuming the webservice in an application, I get a "SoapException" when "import()" is invoked. I have also tried passing the object as a parameter, rather than the header, but the same error occurs. Any ideas?
