web services - Java - How to show Soap Fault -

i have kind of response when having soap fault calling java web service

<soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">     <soap:body>         <soap:fault>             <faultcode>soap:server</faultcode>             <faultstring>fault occurred while processing.</faultstring>             <detail>                 <ns1:waybillregistrationfault xmlns:ns1="http://pod.waybillmanagement.ws.industrysystem.com.ar/">                     <errors xmlns:ns2="http://pod.waybillmanagement.ws.industrysystem.com.ar/">                         <code>80000</code>                         <description>el número de ctg 20140904 ya existe</description>                     </errors>                     <errors xmlns:ns2="http://pod.waybillmanagement.ws.industrysystem.com.ar/">                         <code>1000</code>                         <description>la carta de porte ya se encuentra registrada.</description>                     </errors>                 </ns1:waybillregistrationfault>             </detail>         </soap:fault>     </soap:body> </soap:envelope> 

i did soap handler handlefault method this: public boolean handlefault(soapmessagecontext context) {

    try {         system.err.println("handler handlefault");          if (context.getmessage().getsoapbody().hasfault()) {             soapfault fa = context.getmessage().getsoapbody().getfault();             system.err.println(fa.getfaultstring());             system.err.println("faultcode: " + fa.getfaultcode() + " - detail: " + fa.getdetail());         }         return true;     } catch (soapexception ex) {         system.err.println("soapex " + ex.getmessage());         return true;     } } 

but in output have :

handler handlefault fault occurred while processing. faultcode: soap:server - detail: [detail: null] 

how process errors node?

update:

with fa.getdetail().getfirstchild().gettextcontent() text within xml. how object. waybillregistrationfault think.

if want print fault content xml string , must convert dom instance returned fa.getdetail() string , fa.getdetail().tostring() return ["+getnodename()+": "+getnodevalue()+"]" not content of xml.

try following;

string detailstr=dom2string(fa.getdetail()) system.err.println("faultcode: " + fa.getfaultcode() + " - detail: " + detailstr);    public static final string dom2string(node node) {     try {         if (node == null) {             return null;         }          transformer tf = transformerthreadlocal.get();         // create writer         stringwriter sw = new stringwriter(buffer, integer.max_value);         streamresult result = new streamresult(sw);          // transform         tf.transform(new domsource(node), result);          return sw.getbuffer();     } catch (exception e) {         throw new runtimeexception("could not convert node string", e);     } }
