I cannot send values to Webservice . NET

Question

This is a simple dollar conversion webservice:

public class Callsoap {

    String resultado;
    String erro = null;

public String Call (String ip, String porta, float n){

    String SOAP_ADDRESS = "http://"+ip+":"+porta+"/webservice/WebService.asmx?wsdl";
    String WSDL_TARGET_NAMESPACE = "http://tempuri.org";
    String OPERATION_NAME = "Conversor";
    String SOAP_ACTION = "http://tempuri.org/Conversor";

    int Timeout = 60000;
    HttpTransportSE ht;
    SoapObject request;

    request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);
    request.addProperty("n",String.valueOf(n));

    SoapSerializationEnvelope envelope = getSoapSerializationEnvelope(request);


    ht = new HttpTransportSE(Proxy.NO_PROXY,SOAP_ADDRESS,Timeout);


    try{
        ht.call(SOAP_ACTION,envelope);
        ht.debug = true;
        ht.setXmlVersionTag("<!--?xml version=\"1.0\" encoding= \"UTF-8\" ?-->");

        SoapObject resultadoXML = (SoapObject) envelope.bodyIn;
        SoapPrimitive resultados = (SoapPrimitive) resultadoXML.getProperty("ConversorResult");
        resultado = resultados.toString();
    }catch (Exception e){
        return erro = e.toString();
    }
    request = null;
    ht = null;
    envelope = null;

    return resultado;
}

private final SoapSerializationEnvelope getSoapSerializationEnvelope(SoapObject request) {
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = false;
    envelope.implicitTypes = true;
    envelope.setAddAdornments(false);
    envelope.setOutputSoapObject(request);

    return envelope;
}
}

Answer 1

1. Try to change the line envelope.dotNet = false; for envelope.dotNet = true;
2. Check that the data type generated in the webservice is correct for a correct conversion when bringing the return data;

I use Ksoap2 to work with Webservices . NET, which you can also check is about the need to register on the object SoapSerializationEnvelope the type of data you are using for the return, if the data type is decimal in . NET you will probably have to create a class of Marshal, as set out below:

import java.io.IOException;

import org.ksoap2.serialization.Marshal;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import org.xmlpull.v1.XmlSerializer;

public class MarshalDecimal implements Marshal {

    public Object readInstance(XmlPullParser parser, String namespace, String name, PropertyInfo propertyInfo)
            throws IOException, XmlPullParserException {
        String stringValue = parser.nextText();
        return new java.math.BigDecimal(stringValue);
    }

    public void writeInstance(XmlSerializer writer, Object instance) throws IOException {
        writer.text(instance.toString());
    }

    public void register(SoapSerializationEnvelope cm) {
        cm.addMapping(cm.xsd, "decimal", java.math.BigDecimal.class, this);
    }
}

And in the method getSoapSerializationEnvelope() you will need to add the following instruction:

new MarshalDecimal().register(envelope);
