Consuming web service results in “Unable to handle request without a valid action parameter”

You need to supply the SOAPAction as a HTTP header, not a SOAP header. Here is how a complete request might look like when performed with SoapUI (notice the forth row):

POST /8223third_17/webservices/ItfResidentData.asmx HTTP/1.1Accept-Encoding: gzip,deflateContent-Type: text/xml;charset=UTF-8SOAPAction: "http://tempuri.org/YSI.Interfaces.WebServices/ItfResidentData/GetVersionNumber"User-Agent: Jakarta Commons-HttpClient/3.1Host: www.iyardiasp.comContent-Length: 260<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"                  xmlns:itf="http://tempuri.org/YSI.Interfaces.WebServices/ItfResidentData">   <soapenv:Body>      <itf:GetVersionNumber/>   </soapenv:Body></soapenv:Envelope>

For curl you might use the -H parameter to send the SOAPAction header but I suggest you use SoapUI for your preliminary consumption (it includes the SOAPAction header by default and beats the console any day).

If you do need to use curl, try something like this (all must be on one line; separated for readability):

curl -H "Content-Type: text/xml;charset=UTF-8"      -H "SOAPAction: \"http://tempuri.org/YSI.Interfaces.WebServices/ItfResidentData/GetVersionNumber\""      -d @GetVersionNumber.xml      https://www.iyardiasp.com/8223third_17/webservices/ItfResidentData.asmx

with this in the GetVersionNumber.xml file:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"                  xmlns:itf="http://tempuri.org/YSI.Interfaces.WebServices/ItfResidentData">   <soapenv:Body>      <itf:GetVersionNumber/>   </soapenv:Body></soapenv:Envelope>
