problems with WSDL Proxying

I've read the article on WSDL proxying at
http://web.archive.org/web/20031203040121/devedge.netscape.com/viewsource/2003/wsdl/01/
and have successfully run a similar sample using the proxy with the
google web services api (on Mozilla 1.8b). I'm starting to run into
problems using it against my own WSDL though.

The problem I'm having is identical to a previous posting here
(WSDL/SOAP and .NET?):
http://groups-beta.google.com/group/netscape.public.mozilla.xml/browse_thread/thread/8289cc542cdfb499/08aae14a8e707b5a?q=WSDL+.net+group:netscape.public.mozilla.*#08aae14a8e707b5a

Here is my wsdl:

<definitions

     targetNamespace="urn:myservice:stockQuoteService"
     xmlns="http://schemas.xmlsoap.org/wsdl/"
     xmlns:tns="urn:myservice:stockQuoteService"
     xmlns:plt="http://schemas.xmlsoap.org/ws/2003/05/partner-link/"
     xmlns:xsd="http://www.w3.org/2001/XMLSchema"
     xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
    >
    <message name="response">
        <part name="quote" type="xsd:float"/>
    </message>
    <message name="request">
        <part name="symbol" type="xsd:string"/>
    </message>
    <portType name="StockQuotePT">
        <operation name="Quote">
            <input message="tns:request"/>
            <output message="tns:response"/>
        </operation>
    </portType>
    <binding name="StockQuotePTBinding" type="tns:StockQuotePT">
        <soap:binding style="rpc"
transport="http://schemas.xmlsoap.org/soap/http"/>
        <operation name="Quote">
            <soap:operation style="rpc" soapAction="Quote"/>
            <input>

                <soap:body use="literal"
namespace="urn:myservice:stockQuoteService"/>
            </input>
            <output>
                <soap:body use="literal"
namespace="urn:myservice:stockQuoteService"/>
            </output>
        </operation>
    </binding>
    <service name="myservice">
        <port name="StockQuotePTPort"
binding="tns:StockQuotePTBinding">

            <soap:address
location="http://localhost:9700/orabpel/default/myservice/1.0"/>
        </port>
    </service>
  <plt:partnerLinkType name="StockQuoteSLT">
    <plt:role name="service">
      <plt:portType name="tns:StockQuotePT"/>
    </plt:role>
  </plt:partnerLinkType>
</definitions>

the javascript mostly identical to that in the example, but here is
where i am having trouble:


    function callService(value)
    {
      if (proxy) {

netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");

        var request = new Object();
	request.symbol = 'SNE';
	proxy.Quote(request);        <---

      }

proxy.Quote generates this error:

Error: uncaught exception: [Exception... "Component returned failure
code: 0x80460001 (NS_ERROR_CANNOT_CONVERT_DATA)
[StockQuotePThttp_003a_002f_002flocalhost_003a9700_002forabpel_002fdefault_002fingenium_002fingenium_003fwsdlAsync.gimmeQuote]"
 nsresult: "0x80460001 (NS_ERROR_CANNOT_CONVERT_DATA)"  location: "JS

Any help on this would be greatly appreciated.
