gsoap does not generate C++ proxy classes

Question

I've generated an XSD from a set of example request files for an XML web service (using Xmplify - but I doubt that's important).

When I run this through gsoap, I get no errors or warnings, but even with -i or -j option on soapcpp2, I get no C++ proxy files generated (eg soapProxy.h).

Only the following files are generated:

ns1.nsmap   
request.h
soapC.cpp
soapH.h
soapStub.h

Commands used:

wsdl2h request.xsd 
soapcpp2 -i -C -I/usr/local/share/gsoap/import request.h

I figure there is something specific about the XSD required in order to generate these?

How do I get the proxy files generated? I know I can use without proxy objects, but it looks a lot more messy!

Schema doc is included below.

Thanks for any advice!

Phil.

The wsdl2h tool does not generate proxy and service code for XSD files, since there are no operations defined in these (only in WSDL). You can use the gSOAP-generated (de)serializers for the XSD root elements to send/recv XML data that is (de)serialized from the C++ data types. For example

#include "ns1.nsmap" // ns1 namespaces etc
struct soap *ctx = soap_new();
ns1__REQUEST r;
r.soap_default(ctx); // reset content
r.USERTOKEN = … // set r's content as needed
ctx.os = … // set the output stream
soap_write_ns1__REQUEST(ctx, &r); // serialize REQUEST

You can send/recv data over streams, sockets, etc.
