Web service with KSOAP

Question

I am working on a currency converter application and I cannot get the correct output (I get zero).

I am using webservice from http://www.webservicex.net/ws/WSDetails.aspx?CATID=2&WSID=10 .

WSDL declares this function as:

<wsdl:types> <s:schema elementFormDefault="qualified" targetNamespace="http://www.webserviceX.NET/"> <s:element name="ConversionRate"> <s:complexType> <s:sequence> <s:element minOccurs="1" maxOccurs="1" name="FromCurrency" type="tns:Currency"/> <s:element minOccurs="1" maxOccurs="1" name="ToCurrency" type="tns:Currency"/> </s:sequence> </s:complexType> </s:element> <s:simpleType name="Currency"> <s:restriction base="s:string"> <s:enumeration value="AFA"/> <s:enumeration value="ALL"/> <s:enumeration value="DZD"/> <s:enumeration value="ARS"/> <s:enumeration value="AWG"/> <s:enumeration value="AUD"/> </s:restriction> </s:simpleType> <s:element name="ConversionRateResponse"> <s:complexType> <s:sequence> <s:element minOccurs="1" maxOccurs="1" name="ConversionRateResult" type="s:double"/> </s:sequence> </s:complexType> </s:element> <s:element name="double" type="s:double"/> </s:schema> </wsdl:types> 

My Android class:

 public class MainActivity extends Activity { private static final String NAMESPACE = "http://www.webserviceX.NET"; private static String URL = "http://www.webserviceX.NET/CurrencyConvertor.asmx?WSDL"; private static final String METHOD_NAME = "ConversionRate"; private static final String SOAP_ACTION = "http://www.webserviceX.NET/ConversionRate"; private TextView lblResult; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); lblResult = (TextView) findViewById(R.id.result); SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); PropertyInfo propInfo=new PropertyInfo(); propInfo.name="FromCurrency"; propInfo.type=PropertyInfo.STRING_CLASS; propInfo.setValue("AFA"); PropertyInfo propInfo2 = new PropertyInfo(); propInfo2.name="ToCurrency"; propInfo2.type = PropertyInfo.STRING_CLASS; propInfo2.setValue("AUD"); request.addProperty(propInfo); request.addProperty(propInfo2); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); envelope.dotNet=true; HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); try { androidHttpTransport.call(SOAP_ACTION, envelope); SoapPrimitive resultsRequestSOAP = (SoapPrimitive) envelope.getResponse(); lblResult.setText(resultsRequestSOAP.toString()); } catch (Exception e) { lblResult.setText(e.getMessage()); } } 

Does anyone have a guess about what's wrong?

thanks!

Answer 1

I think your URL string will look like this:

 private static String URL = "http://www.webserviceX.NET/CurrencyConvertor.asmx"; 

And try the following:

 Object resultsRequestSOAP = envelope.getResponse(); 

instead of this:

 SoapPrimitive resultsRequestSOAP = (SoapPrimitive) envelope.getResponse(); 

Answer 2

The description of your service shows that the namespace is http://www.webserviceX.NET/

Try adding extra /
