SimpleDeserializer error from generated client code

[Pridemore, Russell (MAN-Corporate)]

I started with a WSDL file, ran WSDL2Java to generate both client
& server sources.  I successfully deployed the web service with
stubbed methods.  I'm running the TCPMonitor and request & response
look fine as far as I can tell.  But the client blows up with an
exception from SimpleDeserializer.

The type returned by my (RPC-style) web service call is vehicleType:
  <types>
    <xsd:schema targetNamespace="http://manheim.com/simulcast/vehicle";>
      <xsd:simpleType name="numericString">
        <xsd:restriction base="xsd:string">
          <xsd:pattern value="[0-9]+"/>
        </xsd:restriction>
      </xsd:simpleType>

      <xsd:complexType name="vehicleOption">
        <xsd:sequence>
          <xsd:element name="name" type="xsd:string"/>
          <xsd:element name="value" type="xsd:string"/>
        </xsd:sequence>
      </xsd:complexType>

      <xsd:complexType name="vehicleType">
        <xsd:sequence>
          <xsd:element name="id" type="xsd:string"/>  <!-- VIN or other id
-->
          <xsd:element name="make" type="xsd:string"/>
          <xsd:element name="model" type="xsd:string"/>
          <xsd:element name="year" type="ms:numericString"/>
          <xsd:element name="odometer" type="ms:numericString"/>
          <xsd:element name="extColor" type="xsd:string" minOccurs="0"/>
          <xsd:element name="intColor" type="xsd:string" minOccurs="0"/>
          <xsd:element name="bodyStyle" type="xsd:string" minOccurs="0"/>
          <xsd:element name="engine" type="xsd:string" minOccurs="0"/>
          <xsd:element name="fuel" type="xsd:string" minOccurs="0"/>
          <xsd:element name="transmission" type="xsd:string" minOccurs="0"/>
          <!-- all additional options as name/value pairs -->
          <xsd:element name="option" type="ms:vehicleOption" minOccurs="0"
maxOccurs="unbounded"/>
        </xsd:sequence>
      </xsd:complexType>
    </xsd:schema>
  </types>


The response looks like the following.  I was wondering about the 'xmlns=""'
on vehicle:
 <soapenv:Body>
  <GetResponse xmlns="http://manheim.com/simulcast/vehicle";>
   <vehicle xmlns="">
    <id>VIN</id>
    <make>Audi</make>
    <model>S4 Quattro</model>
    <year>2001</year>
    <odometer>012345</odometer>
    <extColor>Black</extColor>
    <intColor>Tan</intColor>
    <transmission>5-speed</transmission>
   </vehicle>
  </GetResponse>
 </soapenv:Body>

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

Any help would be greatly appreciated,
