Is there a way to send a POST request via SOAP in the Pentaho platform? I have the following SOAP package:

Code:
POST /saxtwebservice/saxtwebservice.asmx HTTP/1.1
HPOST /saxtwebservice/saxtwebservice.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.telelogic.com/SAXTWebService/StartSession"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <StartSession xmlns="http://www.telelogic.com/SAXTWebService/" />
  </soap:Body>
</soap:Envelope>
I have seen several forum requests for something similar, but I have not really seen an answer. In this request I am asking for a SessionID for later requests. If I have an example of this call, I can get the other calls to work.
