Please help trying to consume .NET WebService

Hi folks. I've been beating my head against the wall for a couple of  
days now trying to get Axis 1.1 (currently using the final release and  
still having the same problem) to access a .NET Webservice. Most of the  
webservices I've tried to access which are either GLUE or SOAP based  
come through without a hitch. However, other 'untyped' web services are  
causing me some trouble.

The service I'm trying to define llists its SOAP request as

POST /PDCWebService/WeatherServices.asmx HTTP/1.1
Host: weather.unisysfsp.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.unisys.com/WebServices/GetWeather"

<?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>
     <GetWeather xmlns="http://www.unisys.com/WebServices/">
       <ZipCode>string</ZipCode>
     </GetWeather>
   </soap:Body>
</soap:Envelope>

This WSDL is located at  
http://weather.unisysfsp.com/PDCWebService/WeatherServices.asmx?WSDL

What I have tried doing is the following:

try
{
     Service service = new Service();
     call = (Call) service.createCall();

     call.setTargetEndpointAddress( new  
java.net.URL("http://weather.unisysfsp.com/PDCWebService/ 
WeatherServices.asmx") );
     call.setOperationName(new  
QName("http://www.unisys.com/WebServices/", "GetWeatherText"));
      
call.setSOAPActionURI("http://www.unisys.com/WebServices/ 
GetWeatherText");

     call.addParameter("ZipCode", org.apache.axis.Constants.XSD_STRING,  
javax.xml.rpc.ParameterMode.IN );
     call.setReturnType( org.apache.axis.Constants.XSD_STRING );


     Object ret = call.invoke( new Object[]  {"30038"} );

     System.out.println("Return = " + ret + "'");
}
catch (Exception e)
{
     System.err.println("Exception: " + e.toString());

     e.printStackTrace();
}

What happens is that the WebService is invoked, but without the  
parameter ZipCode passed to it. Also, I'm not sure why I has to  
setSOAPActionURI and couldn't find anything in the documentation that  
would state why I would have to do that. I assumed that all I needed to  
do was specify an endpoint, an operation, and a bunch of parameters,  
then invoke the service and wait for the response.

I appreciate ANY help that could be offered including additional  
whitepapers, tutorials, or other documentation on Axis that might not  
be linked to the Apache Axis website.

Thanks in advance!

Gregory,
  Did you try running wsdl2java on the wsdl file and looking at axis's
generated code? I've had great success invoking .net services when using
wsdl2java.
