Hi Noah,
The bad news is this looks to be a bug in how Castor hanndles the
schemna 'ref' attribute.
The good news is that if you change
<xsd:element ref="person"/>
to
<xsd:element name="person" type="personType"/>
It does work although the Authors class gets method
setPerson(java.lang.Object person).
Which isn't ideal, so I think there is also something wrong with using
'type' attribute handling in this scenario. :-(
Anyway I wrote a small test program to make sure its works in a
marhshal/unmarhsall case.
Seems to be OK if you don't mind the uggly cast! ;-)
import java.io.*;
public class Test
{
public static void main(String[] args)
throws Exception
{
// Marshal
Class a = AuthorsDescriptor.class;
Class b = PersonDescriptor.class;
Authors authors = new Authors();
Person person = new Person();
person.setId("ID001");
person.setName("Fred");
authors.setPerson(person);
StringWriter writer = new StringWriter();
authors.marshal(writer);
String xml = writer.toString();
System.out.println(xml);
// Unmarshal
Authors authorsNew = (Authors) Authors.unmarshal(new
StringReader(xml));
Person personNew = (Person) authors.getPerson();
System.out.println(personNew.getName());
}
}
Please can you raise a bug on the Castor JIRA site for this issue.
http://jira.codehaus.org/browse/CASTOR
Cheers,
Andy.

Subject: [castor-user] [XML] Problems with importing no-namespace schema
Hi,
I'm working with a situation where my main schema has a target
namespace, and it imports another schema that does not have a namespace.
This example is taken directly from the O'Reilly book by Eric van der
Vlist called "XML Schema", section 10.9. The main schema file is
called library.xsd and it has a namespace. It is importing a schema
file called person.xsd that has no namespace. When I try to generate
code, the process fails and says that library.xsd is not valid, because
the "person" element (imported from person.xsd) is not resolvable.
I followed the syntax from the book exactly, and both files validate
fine in XML Spy. Is this a bug or am I doing something wrong?
I have the two schema files, the binding file, and the Castor invocation
all below. Note that I am trying to generate Java where each namespace
(including the no namespace) goes into a different package, but I hit
the same error even if I use no binding file and don't try to do this.
Both
type binding and element binding also lead to the error. I am using the
generate imported schemas option. Including rather than importing is
not an option for us; we are using the namespaces and the packages in
order to avoid naming collisions.
Any help here is greatly appreciated!!
Thanks!
