Hi Christophe, I tried many times on gsoap using -t, but it still send out message without xsi:type(maybe it's a gSoap bug), and I checked the other stuff, such as rpc/encoded, they all look right.
Do you think it's because of without xsi:type, that the client can not generate the right object? But I tried to send a 'Shape' object, the client can create a right 'Shape' instance, only if I send the derived class, then client has exception on it. By the way, can you tell me which soap server you used on the server side? I need a c/c++ soap server, so I can put on the embeded system.

Try to make a diff on the code generated by both commands. Also check that you are doing rpc/encoded style. <wsdl:binding name="xxxx" type="xxx"> <wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="xxxx"> <wsdl:input name="xxx"> <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; namespace="xxx" use="encoded"/> </wsdl:input> <wsdl:output name="xxx"> <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; namespace="xxx" use="encoded"/> </wsdl:output> </wsdl:operation> ...
