Hi all,
I am working on a system that provides a soap interface. One of the systems that are going to use the interface is coded in Delphi 7. The web service is developed with WCF, basic http binding, SOAP 1.1.
If I use SOAP UI (JAVA), the service works properly. But Delphi seems to do special things here ;)
This is how the message looks like in SOAP UI:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.xxx.de/xxx">
<soapenv:Header/>
<soapenv:Body>
<ser:GetCustomer>
<!--Optional:-->
<ser:GetCustomerRequest> <!-- this is a data contract -->
<ser:Id>?</ser:Id>
</ser:GetCustomerRequest>
</ser:GetCustomer>
</soapenv:Body>
</soapenv:Envelope>
I am not a delphi developer , but I developed a simple test client to see what's going wrong. This what Delphi sends as a SOAP envelope.
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:NS2="http://services.xxx.de/xxx">
<NS1:GetCustomer xmlns:NS1="http://services.xxx.de/xxx">
<GetCustomerRequest href="#1"/>
</NS1:GetCustomer>
<NS2:GetCustomerRequest id="1" xsi:type="NS2:GetCustomerRequest">
<Id xsi:type="xsd:int">253</Id>
</NS2:GetCustomerRequest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
WCF throws an error that is in German language... ;)
Es wurde das Endelement "Body" aus Namespace "http://schemas.xmlsoap.org/soap/envelope/" erwartet. Gefunden wurde "Element "NS2:GetCustomerRequest" aus Namespace "http://services.xxx.de/xxx"". Zeile 1, Position 599.
Means something like
The Body was expected. But instead the Element "NS2:GetCustomerReques" was found.
Now my questions is: Can I somehow change the way Delphi creates the envelope? Or are the ways to make WCF work with such message formats? Any help is greatly appreciated!
