I checked the website and tried following its guidelines: nothing.
Everything works: the WSDL and the WSDD are correct but at the time the 
exception is throwed the <detail> item of the SOAP response does not contain 
exception fileds but only that "hostname" thing.

<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:Server.userException</faultcode>
      <faultstring>test.MyException</faultstring>
      <detail>
        <ns1:hostname 
xmlns:ns1="http://xml.apache.org/axis/">atlantis</ns1:hostname>
      </detail>
    </soapenv:Fault>
  </soapenv:Body>
</soapenv:Envelope>

Other ideas? It must have happened before... it almost looks like an Axis 
bug.
