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

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: ""

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="" xmlns:xsd="" xmlns:soap="">
    <StartSession xmlns="" />
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.
