Get exception class in kSoap2 on Android

Question

I've got a fault message. I've successfully caught it on Android. What I would like now, is to get the Class for the Exception that triggered the fault. The message goes like this:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <S:Fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">
         <faultcode>S:Server</faultcode>
         <faultstring>Error retrieving user`s [..]</faultstring>
         <detail>
            <ns2:exception class="com.example.UserException_Exception" note="To disable this feature, set com.sun.xml.ws.fault.SOAPFaultBuilder.disableCaptureStackTrace system property to false" xmlns:ns2="http://jax-ws.dev.java.net/">
               <message>EError retrieving user`s [..]</message>
               <ns2:stackTrace>
                  <ns2:frame class="sun.reflect.DelegatingMethodAccessorImpl" file="DelegatingMethodAccessorImpl.java" line="43" method="invoke"/>

                  <ns2:frame class="java.lang.Thread" file="Thread.java" line="722" method="run"/>
               </ns2:stackTrace>
            </ns2:exception>
         </detail>
      </S:Fault>
   </S:Body>
</S:Envelope>

I've removed a part of the trace, because it is not relevant.

This is the code' im using for the transaction:

public static Long getCount(String id)
            throws XmlPullParserException, IOException {

        SoapObject request = new SoapObject(NAMESPACE, "getCount");
        request.addProperty("id", id);

        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        soapEnvelope.dotNet = true;

        soapEnvelope.setOutputSoapObject(request);

        System.setProperty("http.keepAlive", "false");

        HttpTransportSE htse = new HttpTransportSE(URL);

        htse.call(URL, soapEnvelope, null);

        SoapPrimitive response = (SoapPrimitive) soapEnvelope.getResponse();
        Long count = null;
        try {
            timestampCount = Long.parseLong(response.toString());
        } catch (NumberFormatException e) {
            e.printStackTrace();
        } catch (SoapFault e) {
            e.printStackTrace();
        }


        return count;
    }

So, how do I go about getting class="com.ltc.mid.pdf.UserCertificateException_Exception" from the SoapFault object?

Just to be perfectly clear: I'm looking for either:

• Java code to get the class atribute from <detail><exception> element
• SOAP parsing code to get class atribute from <detail><exception> element

Thanks!

Answer 1

I managed to solve this myself.

So, taking the format displayed in the question into consideration, this is what works for me:

soapEnvelope.setOutputSoapObject(request);

        System.setProperty("http.keepAlive", "false");

        HttpTransportSE htse = new HttpTransportSE(URL, 60000);

        //htse.debug=true; //This directive is helpful while debugging
        try {
            htse.call(URL, soapEnvelope, null);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        }
        if (soapEnvelope.bodyIn instanceof SoapFault) {
            Node details = ((SoapFault) soapEnvelope.bodyIn).detail;
            Element detailElem = (Element) details.getElement(0).getChild(0);
            String exc = detailElem.getName();
            if (exc.equals("SomeSpecificException")) {
                throw new SomeSpecificException();
            }
            throw new Exception("SOAP PROBLEMS!");
        }
