Why does the service exchange strings rather than typed XML? If it's a
web service, it should define its interface using a
language-independent API, such as WSDL or a schema. Did the service
provider at least provide you with a description of the expected
string format? The first place I'd look is at the input message. My
guess is that it isn't formatted properly.
