How to parse soapfault's detail? - ksoap2

Question

I am trying to get the values inside this soap fault's "detail", but I haven't found any ways of doing so.
The response from the server:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<faultcode>SOAP-ENV:Client</faultcode>
<faultstring>Many Errors</faultstring>
<detail>
<error_id>2</error_id>
<errors>
<error>
<error_id>1</error_id>
<error_description>Unknown Error</error_description>
</error>
<error>
<error_id>5</error_id>
<error_description>Not Authorized</error_description>
</error>
<error>
<error_id>9</error_id>
<error_description>Password should be at least 6 characters including one letter and one number</error_description>
</error>
</errors>
</detail>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I need to get the error_ids along with their respective error_descriptions. So far I've only managed to get the detail via kSOAP with the following way:
if (envelope.bodyIn instanceof SoapObject) {
return envelope.bodyIn.toString();
} else if (envelope.bodyIn instanceof SoapFault) {
SoapFault e = (SoapFault) envelope.bodyIn;
Node details = ((SoapFault) envelope.bodyIn).detail;
}
but I haven't managed to get a single value I need when I try to "navigate" through it.
Any help is greatly appreciated. I have found little to non information about handling soap faults with ksoap2 online...

Answer 1

The following code handles better
Iterator it = soapFaultClientException.getSoapFault().getFaultDetail().getDetailEntries();
while (it.hasNext())
{
Source errSource = it.next().getSource();
#SuppressWarnings("unchecked")
JAXBElement errJaxb = (JAXBElement) springWebServiceTemplate.getUnmarshaller().unmarshal(errSource);
ServerCustomizedError err = errJaxb.getValue();
....
}

Figured it out after all. Here is the way to do it:
Node details = ((SoapFault) envelope.bodyIn).detail;
Element detEle = details.getElement(NAMESPACE, "detail");
List<Error> errorList = new ArrayList<NewConnector.Error>();
Element idEle = detEle.getElement(NAMESPACE, "error_id");
str.append("id: " + idEle.getText(0));
str.append("\n");
Integer id = Integer.valueOf(idEle.getText(0));
if (id == 2) {
// many errors
Element errors = detEle.getElement(NAMESPACE, "errors");
int errorChildCount = errors.getChildCount();
for (int i = 0; i < errorChildCount; i++) {
Object innerError = errors.getChild(i);
if (innerError instanceof Element) {
Element error_id = ((Element) innerError).getElement(
NAMESPACE, "error_id");
Element error_descrion = ((Element) innerError)
.getElement(NAMESPACE, "error_description");
Error singleError = new Error(Integer.valueOf(error_id
.getText(0)), error_descrion.getText(0));
errorList.add(singleError);
str.append(singleError.toString() + "\n");
}
}
str.append("Found " + errorList.size() + " errors.\n");
str.append("errorscount:" + errors.getChildCount());
The code obviously needs improvements, but it's just a showcase of how to get each value. Cheers

I use the following method:
/**
* Method to retrieve the errorMessage from the given SoapFault.
* #param soapFault
* #return String representing the errorMessage found in the given SoapFault.
*/
private static String getSoapErrorMessage (SoapFault soapFault) {
String errorMessage;
try {
Node detailNode = soapFault.detail;
Element faultDetailElement = (Element)detailNode.getElement(0).getChild(1);
Element errorMessageElement = (Element)faultDetailElement.getChild(0);
errorMessage = errorMessageElement.getText(0);
}
catch (Exception e) {
e.printStackTrace();
errorMessage = "Could not determine soap error.";
}
return errorMessage;
}
