JAXB problems unmarshalling

Question

I used xjc to generate a set of elements from the schema shown below:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.doc.state.nc.us/doccodes" xmlns="http://www.doc.state.nc.us/doccodes" xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
     <xsd:element name="codeTable" type="CodeTable"/>
     <xsd:element name="codeRequest" type="CodeRequest"/>
     <xsd:complexType name="CodeTable">
          <xsd:sequence>
               <xsd:element name="codename" type="xsd:string"/>
               <xsd:element name="codes" type="Codes"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:complexType name="Codes">
          <xsd:sequence>
          <xsd:element name="code" type="Code" minOccurs="1" maxOccurs="unbounded"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:complexType name="Code">
          <xsd:sequence>
                    <xsd:element name="identifier" type="xsd:string"/>
                    <xsd:element name="description" type="xsd:string"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:complexType name="CodeRequest">
          <xsd:sequence>
               <xsd:element name="application" type="xsd:string"/>
               <xsd:element name="token" type="xsd:string"/>
               <xsd:element name="codename" type="xsd:string"/>
          </xsd:sequence>
     </xsd:complexType>
</xsd:schema>
I have successfully been able to marshall an xml file using the following code:
jc = JAXBContext.newInstance( "nc.doc.nexus.code.jaxb.model");
CodeTable codeTable = new CodeTable();
Codes facilityCodes = new Codes();
List<Code> codeList = facilityCodes.getCode();
codeList.addAll(persistables); // where persistables is an ArrayList of Code objects
codeTable.setCodes(facilityCodes);
codeTable.setCodename("facilityCode");
JAXBElement<CodeTable> codeTableElement = (new ObjectFactory()).createCodeTable(codeTable);
Marshaller m = jc.createMarshaller();
m.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );
m.marshal(codeTableElement, System.out);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db;
try {
db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
m.marshal(codeTableElement, doc);
return doc;
catch (ParserConfigurationException e) {
The marshalling works just fine, and results in the following xml:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:codeTable xmlns="http://www.doc.state.nc.us/doccodes" xmlns:ns1="http://www.doc.state.nc.us/doccodes">
<ns1:codename>
facilityCode </ns1:codename>
<ns1:codes>
<ns1:code>
<ns1:identifier>
X001 </ns1:identifier>
<ns1:description>
DHO DISTRICT 1 </ns1:description>
</ns1:code>
<ns1:code>
<ns1:identifier>
X002 </ns1:identifier>
<ns1:description>
DHO DISTRICT 2 </ns1:description>
</ns1:code>
<ns1:code>
<ns1:identifier>
X003 </ns1:identifier>
<ns1:description>
DHO DISTRICT 3 </ns1:description>
</ns1:code>
</ns1:codes>
</ns1:codeTable>
My code to unmarshall this xml document is as follows:
JAXBContext jc;
try {
jc = JAXBContext.newInstance( "nc.doc.nexus.code.jaxb.model");
Unmarshaller unmarshaller = jc.createUnmarshaller();
JAXBElement<CodeTable> codeTableElement =
(JAXBElement<CodeTable>)unmarshaller.unmarshal(aDocument);
catch (JAXBException e) {
     throw new DeserializerException(e);
Now the problem. When I attempt to unmarshall this xml, I get the following UnmarshalException:
unexpected element (uri:"", local:"ns1:codeTable"). Expected elements are <{http://www.doc.state.nc.us/doccodes}codeRequest>,<{http://www.doc.state.nc.us/doccodes}codeTable>
I've made countless attempts to alter the unmarshal code in an attempt to determine if I had just coded it wrong, or whether jaxb is not able to interpret namespaces or schemas correctly. I have to assume the latter at this point. Can anybody shed any light on this?
By the way, below is the xjc generated class CodeTable:

UPDATE: I changed the unmarshal code to unmarshal a File instead of a DOM Document, and it works. This is the revelation I was hoping not to come to. I really don't want to have to serialize my Document to a file and then unmarshal that file from disk. This would not be an acceptable solution for a large J2EE application with many web services servicing 10000 clients. Does anybody know why the unmarshal method that accepts a DOM Document does not work?
