SoapException invalid SOAPAction

[Markus Broy]

Hi,

I am trying to call a webmethod on a web server from an onther server. Doing
this I get the following exception (German):

System.Web.Services.Protocols.SoapException: Die Anforderung kann ohne
gültigen action-Parameter nicht behandelt werden. Geben Sie eine gültige
SOAPAction an.
at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClient
Message message, WebResponse response, Stream responseStream, Boolean
asyncCall)
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String
methodName, Object[] parameters)

Translated (not exactly the english message but the meaning): The request
cannot be executed without a valid action parameter.

If I call the same webmethod from another program installed on the web
server everything works fine.

Any ideas?

Thank you in advance.

You're missing the SOAPAction in the http header. The SOAPAction tells
the server which method in the service to call..

try this...
[objName].setRequestHeader "SOAPAction", "[the actual value]"
