Web Services are a complex issue. In many cases the WS will present an
object to be populated and passed back. Your zip code example expects a
string input, no big deal.
I am currently writing a WS to take my edi inbound data and present it to
my ERP system So many trading partners and many variations on how an 850
is used is part of the joy. Defining what is presented and what is needed
to complete a Sales Order is what my WS app fulfills.
VFP will only work with SOAP and maybe an early version, not sure on that.
My WS is all json
I would recommend you finding out how to work your object that
you instantiate as the WS.
Your example above may have features that are one level below root of the
object.
loZipWS.??? may have all of the functionality you are looking for. In
general that is how just about all of the java WS apps that I
have interacted with have worked. Just because you can instantiate it
doesn't mean it will do anything until you reference a part of it's
internals.
In VisualStudio, any version, after you add the WS to your project you can
open the object explorer and see exactly what is in there, and they will
display exactly what functions are available as well as what object type
they expect.
Get very familiar with containers of containers!
