Hello Arnaud,
Thank you for your suggestion. We made use of the setNamespaceMapping
method to regain the
"METS:" namespace prefix, when Marshalling, but, we are still running into
a problem in retaining the
"xlink:" namespace prefix.
The METS.xsd has the schema namespace declarations:
<xsd:schema targetNamespace="http://www.loc.gov/METS/";
xmlns:xlink="
http://www.w3.org/TR/xlink";
xmlns:xsd="
http://www.w3.org/2001/XMLSchema";
xmlns="
http://www.loc.gov/METS/";
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xsd:import namespace="http://www.w3.org/TR/xlink";
schemaLocation="/path1/path2/path3/xlink.xsd" />
...as you may recall. We suspect the imported xlink.xsd may lost during
UnMarshalling, although we don't encounter
any Castor processing error(s) when running our processor. We have been
using the following calls, per your suggestion:
marshaller.setNamespaceMapping("METS","
http://www.loc.gov/METS/";);
marshaller.setNamespaceMapping("xsi","
http://www.w3.org/2001/XMLSchema-instance";);
marshaller.setNamespaceMapping("xlink","
http://www.w3.org/TR/xlink";);
marshaller.marshal(metsDoc);
but the "xlink:" prefix for the xlink namespace is not getting output (as
we showed in earlier email re the
"xlink:href" example).
Question: is there a way to ask of something like the SchemaUnmarshaller
that we wish to assure the retention of
the namespace mapping of "xlink", "http://www.w3.org/TR/xlink";? The
unique aspect of the xlink.xsd is that it
contains attributes, only, and it is not a schema that can be compiled
separately to create its own classes.
I hope the above makes sense -- please let me know if we might be able to
request that Castor retain the imported
namespace/schemaLocation -- or, if I've misunderstood the processing logic
here.
Many thanks,
..Mike Sanderson & Ho-chun Chin

Hi Mike,
Currently the Source Generator is not keeping the prefix chosen in the
XML Schema. It will assume that the target namespace is the default
namespace (no prefix), we'll improve that in future releases.
What you can do for the moment is instantiate your own Marshaller and
use setNamespaceMapping to define your (prefix, namespace) mapping.
Let me know if it is ok for you,
Arnaud
