This is a simple example showing how to use Apache SOAP as a client
to a service implemented using Microsoft SOAP. 

The service is described here:
	http://www.itfinity.net/soap/guid/details.html

In order to make it work, you have to tell Apache SOAP how to
deserialize the response by telling it the types to map the
results to. In this case, the response only contains the element
<Result>...</Result> and the content of that element should 
be treated as a string. The Apache SOAP client-code is informed
of this by the following lines of code in the client:

    // define deserializers for the return things (without xsi:type)
    SOAPMappingRegistry smr = new SOAPMappingRegistry ();
    StringDeserializer sd = new StringDeserializer ();
    smr.mapTypes (Constants.NS_URI_SOAP_ENC,
                  new QName ("", "Result"), null, null, sd);

And then by using this SOAPMappingRegistry in the call:
    Call call = new Call ();
    call.setSOAPMappingRegistry (smr);


The smr.mapTypes line tells Apache SOAP that if it sees an 
unqualified element in the response encoded in SOAP encoding
of a call named "Result" to deserialize it using a StringDeserializer,
which returns a String object. 

The sample client is hardcoded to talk to the actual service
URL, however, it takes an optional URL as argument which would
override the hardcoded URL. This allows you to route the call/response
via the the tunnel to see what's going on.

Additionally, you can route the call through an HTTP proxy server by
specifying the following arguments on the command line:
  -p myproxy.mycompany.com:8080
where "myproxy.mycompany.com" is the hostname or dotted-decimal IP address
of your proxy server, and 8080 the port number.
