Problem:
I have a SOAP service with the following simplified WSDL:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="http://new.webservice.namespace" targetNamespace="http://new.webservice.namespace">
<wsdl:types>
<xs:schema targetNamespace="http://new.webservice.namespace" elementFormDefault="qualified"/>
</wsdl:types>
<wsdl:message name="NewMessageRequest">
<wsdl:part name="parameter" type="xs:string"/>
</wsdl:message>
<wsdl:message name="NewMessageResponse">
<wsdl:part name="result" type="xs:string"/>
<wsdl:part name="param2" type="xs:string"/>
</wsdl:message>
<wsdl:portType name="NewPortType">
<wsdl:operation name="NewOperation">
<wsdl:input message="tns:NewMessageRequest"/>
<wsdl:output message="tns:NewMessageResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="NewBinding" type="tns:NewPortType">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="NewOperation">
<soap:operation soapAction="urn:#NewOperation"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="NewService">
<wsdl:port name="NewPort" binding="tns:NewBinding">
<soap:address location="No Target Adress"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
Notice the output message has two parts.
When invoking the SOAP services with SoapUI, the services implemented with the gSOAP framework returns a response which does not comply with the WSDL:
This is the SoapUI request:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:new="http://new.webservice.namespace">
<soapenv:Header/>
<soapenv:Body>
<new:NewOperation>
<parameter>Hello</parameter>
</new:NewOperation>
</soapenv:Body>
</soapenv:Envelope>
This is the gSOAP WS response:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:new="http://new.webservice.namespace">
<soapenv:Header/>
<soapenv:Body>
<new:NewOperationResponse>
<result xsi:nil="true"/>
<param2>Hello World</param2>
</new:NewOperationResponse>
</soapenv:Body>
</soapenv:Envelope>
SoapUI complains with the following error:
line5: Element has xsi:nil attribute but is not nillable
Question:
How can I fix the WSDL so the message part is nullable?
