spring & web service client - Fault Detail [closed]

Question

How could I get the Fault Detail sent by a SoapFaultClientException ? I use a WebServiceTemplate as shown below :

WebServiceTemplate ws = new WebServiceTemplate();
ws.setMarshaller(client.getMarshaller());
ws.setUnmarshaller(client.getUnMarshaller());
try {
    MyResponse resp = (MyResponse) = ws.marshalSendAndReceive(WS_URI, req);
} catch (SoapFaultClientException e) {
     SoapFault fault =  e.getSoapFault();
     SoapFaultDetail details = e.getSoapFault().getFaultDetail();
      //details always NULL ? Bug?
}

The Web Service Fault sent seems correct :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
  <soapenv:Fault>
     <faultcode>soapenv:Client</faultcode>
     <faultstring>Validation error</faultstring>
     <faultactor/>
     <detail>
        <ws:ValidationError xmlns:ws="http://ws.x.y.com">ERR_UNKNOWN</ws:ValidationError>
     </detail>
  </soapenv:Fault>
</soapenv:Body>

Thanks

From the Javadocs for the marshalSendAndReceive method it looks like the SoapFaultClientException in the catch block will never happen.

From the API it looks like the best bet for determining the details of the fault is to set a custom Fault Message Receiver.

I also had the problem that getFaultDetail() returned null (for a SharePoint web service). I could get the detail element out by using a method similar to this:

private Element getDetail(SoapFaultClientException e) throws TransformerException {
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMResult result = new DOMResult();
    transformer.transform(e.getSoapFault().getSource(), result);
    NodeList nl = ((Document)result.getNode()).getElementsByTagName("detail");
    return (Element)nl.item(0);
}

After that, you can call getTextContent() on the returned Element or whatever you want.

Check out what type of HTTP response you get when receiving Soap Fault. I had the same problem when SOAP Fault responses using HTTP 200 instead of HTTP 500. Then you get:

JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException

When you change WebServiceTemplate connection fault settings as below:

WebServiceTemplate webServiceTemplate = getWebServiceTemplate();
webServiceTemplate.setCheckConnectionForFault(false);

then you can properly catch SoapFaultClientException
