Hi,
I've found a potential bug in JAX-WS when trying to parse a SOAP Fault... description below... Where do I register this so it can be assessed and fixed?
My webservice is returning a SOAP Fault like this…

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:tns="http://www.esri.com/schemas/ArcGIS/10.1" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
\<tns:Fault xmlns:my="urn:myNamespace" xmlns:tns="[http://schemas.xmlsoap.org/soap/envelope/](http://schemas.xmlsoap.org/soap/envelope/)">
<faultcode>tns:Client</faultcode>
<faultstring>Not found - parcel_key = 283458</faultstring>
<detail>
\<exception>this is my exception\</exception>
\</detail>
</tns:Fault>
</soap:Body>
</soapenv:Envelope>
When I try to call this web service, using JAX-WS, I get an unexpected NPE – Null Pointer Exception

Exception in thread "main" javax.xml.ws.WebServiceException: java.lang.NullPointerException

The cause seems to be this code…

Possible solution would be…
public static boolean isStackTraceXml(Element n) {
return n.getLocalName().equals(LOCAL\_NAME) && n.getNamespaceURI() != null && n.getNamespaceURI().equals(NS);
}
