Re: Deserialization problem

[Minh Kama Yie]

Hi Rahul,

The problem is the namespace in which the result of the service is defined. 
If you map the result using the the SOAPMappingRegistry like so:

{
        ...
        SOAPMappingRegistry smr = new SOAPMappingRegistry();
        smr.mapTypes(Constants.NS_URI_SOAP_ENC, new 
QName("http://localhost/";, "AddResult"), Integer.class, null, new 
IntObjectDeserializer());
        call.setSOAPMappingRegistry(smr);
        ...
}

then it should map to the correct encoding type. Currently you're telling the 
deserializer to use the "http://schemas.xmlsoap.org/soap/encoding/"; namespace 
but the service is defining it in the "http://localhost/"; namespace.  ( see 
the c# line with the code {ResponseNamespace="http://localhost/"})


Hope that helps :)

Hi,
I am trying to invoke a .Net enabled web service using Java with Apache SOAP
 toolkit.

I get the following exception:

Here's my trial code:
/*

// Required due to use of URL class , required by Call class
import java.net.*;

/**

public class SoapClient1 {

    /** Creates new SoapClient1 */
    public SoapClient1() {
    }

    public static void main(String[] args) {
        Call call = new Call();
        call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
        call.setTargetObjectURI("urn:CalcSoap");
        call.setMethodName ("Add");
        Vector params=new Vector();
        params.addElement (new Parameter ("x", String.class, "1", null));
        params.addElement(new Parameter ("y", String.class, "2", null));
        call.setParams(params);
        try {
            URL url = new URL ("http://161.85.17.164/calc.asmx";);
            Response resp = call.invoke(url, "http://localhost/Add";);
            if (resp.generatedFault()) {
                Fault fault=resp.getFault();
                System.out.println(" Fault code: " + fault.getFaultCode());
                System.out.println(" Fault string: "+fault.getFaultString());
            }
            Parameter result=resp.getReturnValue();
            Object o = result.getValue();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}



However i am able to iunvoke the service quite easily using c# and the proxy
 code that VStudio .Net generates.
Here's the proxy file that is generated by Vstudio.net (if it is of any
 use...)
