RE: SAXException trying to deserialize this fault

[Anne Thomas Manes]

There are two problems with this fault message:
1- The <SOAP-ENV:Fault> element must be the first and only child element in
the <SOAP-ENV:Body> element. It cannot be a child of the <ns1:SomeFunction>
element. If you want to return the <ns1:SomeFunction> information in the
fault, it must be encoded within the <detail> element.
2- Content in the <detail> message must be namespace qualified.

Subject: SAXException trying to deserialize this fault

I'm trying to figure out why Axis throws a SAXException trying to 
deserialize the following SOAP message containing a fault:

<SOAP-ENV:Envelope 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; 
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"; 
xmlns:xsd="http://www.w3.org/1999/XMLSchema";>
  <SOAP-ENV:Body>
  <ns1:SomeFunction xmlns:ns1="urn:foo">
  <Param1 xsi:type="xsd:string">some value</Param1>
  <Param2 xsi:type="xsd:string">some value</Param2>
    <SOAP-ENV:Fault>
    <faultcode xsi:type="xsd:string">Client</faultcode>
    <faultstring xsi:type="xsd:string">Client request/data 
invalid</faultstring>
      <detail>
      <message xsi:type="xsd:string">some message</message>
      <errorcode xsi:type="xsd:string">-5</errorcode>
      </detail>
    </SOAP-ENV:Fault>
  </ns1:SomeFunction>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The code I'm using:

Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(endpoint);
call.setSOAPActionURI("SomeAction"); 
call.setOperationName(new QName("urn:foo", "SomeFunction"));
call.addParameter("Param1", org.apache.axis.Constants.XSD_STRING, 
javax.xml.rpc.ParameterMode.IN);
call.addParameter("Param2", org.apache.axis.Constants.XSD_STRING, 
javax.xml.rpc.ParameterMode.IN);
call.setReturnType(XMLType.XSD_STRING);
String result = (String)call.invoke( new Object[] { "value1", "value2" } );

The exception stack trace that results:

org.xml.sax.SAXException: SimpleDeserializer encountered a child 
element, which is NOT expected, in something it was trying to deserialize.
