I'm trying to unmarshal an xml file with jaxb 2.1, and getting the error:-
"unexpected element
(uri:"
http://www.T45PCO.com/combat_system/encyclopaedic_data",
local:"Header"). Expected elements are<{}Header,{}Odc>, ignoring this node."
The code looks like:-
JAXBContext jc = ...//create JAXBContext
Unmarshaller unmarshaller = jc.createUnmarshaller();
unmarsaller.setEventHandler(new DefaultValidationEventHandler());
Object o = unmarshaller.unmarshal(new
FileInputStream(filename)); // fails here
OdcStoreDataT data = ((JAXBElement<OdcStoreDataT>)o).getValue();
//OdcStoreDataT
@XMLRootElement(name="ODC_Store_Root",
namespace=
http://www.T45PCO.com/combat_system/encyclopaedic_data)
@XMLAccessorType(XMLAccessType.FIELD)
@XMLType(name="Odc_Store_Data_T", propOrder = {"header","odc"})
public class OdcStoreDataT{
@XMLElement(name="Header", required=true)
protected HeaderT header;
@XMLElement(name="Odc", required=true)
protected List<G600dcStoreDataT> odc;
// generated get/set methods
}
I had hoped that using jaxb would be the simple solution since I'm not an
XML expert. I'm guessing its something to do with the namespace that Header
belongs to. I can marshal a new set of data out, and then read that in, but
the marshaled file has inserted ns2: namespace declarations in front of
Header (and standalone="yes"), so I guess that allows it to find/create the
appropriate automatically generated java type, I don't know. I can't edit
all the xml files, what changes do I need to make to the schema file to fix
this please? Or do I need to somehow put the namespace in the java code?
I've tried looking at the FAQ and articles, but can't find anything
explaining clearly how XML namespaces are handled by jaxb. I have the Java
6 download, which I think included jaxb 2.1(?) but not, AFAIK, the
namespace-prefix sample?
Thanks,
Sean
