SOAP SEND error

[kaush]

Hi all,

I am trying to send a SOAP Message to a URL (I have a
readymade SOAP message). I am constructing the SOAP envelope ( I am
populating the header and body of the envelope using
envelope.Header.InnerText and envelope.Body.InnerText properties).
When I try to send the envelope, an exception occurs "WSE811: Action
must be specified if the message is not a response ".

I am not sure how to set the action property if there is one.

Any pointers ?

Thanks
