Connecting to an external Web Service

Question

All-
I have read the "Invoking a Synchronous Web Service" tutorial and it has great coverage on how to connect to Web Service hosted on OC4J. I have written a web service that is standalone using gSoap and C++ and do not know how to modify the partnerLink on page 20 for such a service. I can access the service with the following url, http://localhost:18088/
So I will need to send a SOAP message to that url.
Something that looks like this
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:elt="http://iec.elt.interoperability/">
<SOAP-ENV:Body>
<elt:soap-openImage>
<elt:path>\\server\\images\\test.jpg</elt:path>
</elt:soap-openImage>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Thanks for your help. If you just tell me what document or book to read or sections of book to read that would be great!!!!

I'm getting these error messages,
