I am attempting to connect to a web service that is using apache soap. I am using MSSOAP client VFP 8.0. I am getting the following back:

HTTP/1.1 500 Internal Server Error
content-type: text/xml; charset=utf-8
cache-control: no-cache="set-cookie, set-cookie2"
date: Mon, 02 May 2005 16:37:38 GMT
content-length: 568
content-language: en
server: IMB_HTTP_SERVER/1.3.26.2 Apache/1.3.26(Unix)
Set-Cookie: AMWEBJCT!.... JSESSIONID=....

Error: 1429 - OLE IDispatch exception code 0 from /fsWebService/servelet/rpcrouter: No Deserializer
found to deserialize a ':UserName' using encoding style
'http://schemas.xmlsoap.org/soap/encodong/'...

I have exhausted google trying to figure out the deserializer.
I appreciate any pointers.

Code:

LOCAL oFSHttp AS "MSSOAP.SoapClient30"
* Do not remove or alter following line. It is used to support IntelliSense for your XML Web service.
*__VFPWSDef__: loImdsWS = c:\lcsweb\imds.wsdl , ImdsService , ImdsWS
LOCAL loException, lcErrorMsg, loWSHandler, lcHeader, lcResult
lcHeader = ''
lcHeader = SPACE(4096)
TRY
	oFSHttp = NEWOBJECT("MSSOAP.SoapClient30")
	oFSHttp.MSSoapInit("file://c:\lcsweb\wsdl\FSHttpService.wsdl")
	oFSHttp.ConnectorProperty("ConnectTimeout") = 300000
	oFSHttp.ConnectorProperty("EndPointURL")="https://phony.web.address/fsWebService/servlet/rpcrouter"
	oFSHttp.ConnectorProperty("RequestHTTPHeader") = "Cookie:" + uWebCookie
	oFSHttp.ConnectorProperty("ProxyServer")="<CURRENT_USER>"
	* Call your XML Web service here.  ex: leResult = loImdsWS.SomeMethod()
	lcResult = oFSHttp.FSLogon(thisform.username, thisform.password, thisform.account, ;
		thisform.projectid, thisform.terminalid)
	lcHeader = oFSHttp.ConnectorProperty("ResponseHTTPHeader")
	
CATCH TO loException
	lcHeader = oFSHttp.ConnectorProperty("ResponseHTTPHeader")
	MESSAGEBOX(lcHeader)
	lcErrorMsg="Error: "+TRANSFORM(loException.Errorno)+" - "+loException.Message
	DO CASE
	CASE VARTYPE(oFSHttp)#"O"
		* Handle SOAP error connecting to web service
	CASE !EMPTY(oFSHttp.FaultCode)

	OTHERWISE
		* Handle other error
	ENDCASE
	* Use for debugging purposes
	MESSAGEBOX(lcErrorMsg)
	SET STEP ON 
FINALLY
