I try to create a weather webservices client, follow the tutorial:

http://www.devarticles.com/c/a/Delphi-Kylix/Creating-a-Web-Service-Client-wi
th-Delphi/

but it does not work.

The soap request is:

<?xml version="1.0"?>
<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/"><NS1:GetW
eatherByZipCode xmlns:NS1="http://www.webservicex.net"><ZipCode
xsi:type="xsd:string">30350</ZipCode></NS1:GetWeatherByZipCode></SOAP-ENV:Bo
dy></SOAP-ENV:Envelope>

And the header of the soap response is:

<?xml version="1.0" encoding="utf-8"?><soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultco
de>soap:Server</faultcode><faultstring>System.Web.Services.Protocols.SoapExc
eption: Server was unable to process request. ---&gt; System.Exception:
Error occured when get webservices  record ---&gt;
System.Data.SqlClient.SqlException: Procedure or function 'GetLatByZipCode'
expects parameter '@zipCode', which was not supplied.

Seems like I missed the zipCode parameter but it is already in the header.

After comparing the imported WSDL with the example on the web, I found that
the following line is missed in my imported unit:

InvRegistry.RegisterInvokeOptions(TypeInfo(WeatherForecastSoap),
ioDocument);

After adding it, the project works.  I just wonder if I missed anything
during the import process.  I already have D6 update 1,2 and RTL 1-3.  And I
would to have the import working with other web services.

I also tried D7 and the same problem occur.


Thanks in advance!
