SoapException: Missing a valid action parameter.

Hi,
I'm a bit of a newbie at webservices but here goes:

I have a webservice developed with VS (using C#), no custom headers or
anything like that, just a basic webmethod:

[WebMethod]
public int TransferOrders(string xmlDoc , string languageCode, out string
result)

When testing against localhost,everything works as planned, but then I
uploaded it to "real" host and everything checks out. The asmx-page appears
when I type in the path to the remote host and so on.
But when I try to invoke the service, using my client app, I get a
SoapException:
"Additional information: Unable to handle request without a valid action
parameter. Please supply a valid soap action."

Does this has anything to do with the fact that I'm sitting behind a
firewall (I thought that soap-traffic just passed right through firewalls),
or is it caused by something else?

Any ideas??

Thanks in advance
Jon
