setBaseSchemaLocation(System.getProperty("user.dir")); won't work, because there is no protocol - you'll need to do the following:
setBaseSchemaLocation("File:///" + System.getProperty("user.dir"));

The Schemas can be downloaded from:-

In the xsd directory you will find the UBL-Invoice-2.0.xsd that I was trying
to load.
I am running on Linux, so I set the base location to:-
setBaseSchemaLocation(System.getProperty("user.dir"));
I did also try adding in a "/" on the end just in case.
in the CustomClassGenerator just before I call:-
Source source = super.resolveSchema(sourceXSD, namespace, schemaLocation);

Also why does the else below (and that in the default one) use new URL
when surely it should use new URI?

Hey David,
To handle this scenario you will need to implement a SchemaResolver
(org.eclipse.persistence.sdo.helper package) that can load the doc
based on the relative path. To do this, you can simply extend the
default resolver we provide
(org.eclipse.persistence.sdo.helper.DefaultSchemaResolver) and
override the resolveSchema(Source, String, String) method to handle
this case. Note that the schema resolver is passed in as a parameter
in the define method on the delegator.
Here's an example of a custom resolver:
public class CyclicSchemaResolver extends DefaultSchemaResolver
{ public Source resolveSchema(Source sourceXSD, String namespace,
String schemaLocation) {
if (schemaLocation != null &&
!schemaLocation.equals("")) { return super.resolveSchema(sourceXSD,
namespace, schemaLocation); }
schemaLocation = namespace.equals("uri") ? "Cyclic1.xsd"
: "Cyclic2.xsd";
URL schemaUrl = null;
try {
if (getBaseSchemaLocation() != null) {
// Attempt to resolve the schema location
against the base location
URI baseUri = new URI(getBaseSchemaLocation());
URI resolvedUri =
baseUri.resolve(schemaLocation); schemaUrl = resolvedUri.toURL();
} else {
schemaUrl = new URL(schemaLocation);
}
} catch (Exception e) {
return null;
}
return new StreamSource(schemaUrl.toExternalForm());
}
}
Please let me know if you have any questions.

Looking at the relevant line in the xsd file, it starts:-

schemaLocation="../common/UBL-CommonAggregateComponents-2.0.xsd"/>
and I think it is complaining about schemaLocation.
I guess this is because of the lack of a protocol.
I am using Sun Java 6 on linux, using its default XML code.
Perhaps the code in DefaultSchemaResolver needs to trap this
exception and try adding file:/// to the front of the URL. I do
not know whether this is really a fault with the OASIS xsd file but
they have been in the field for a while and I am sure of XML
parsers generally objected to this it would have been picked up as
a problem.
In fact looking at the code, should DefaultSchemaResolver.java line
55 which currently reads:-
schemaUrl = new URL(schemaLocation);
read instead:-
schemaUrl = new URI(schemaLocation).toUrl();
as the javadoc for URI says that it can handle this kind of
specification without a protocol.
