Referencing XSD Components from Java Blackbox [message #1018517]

I currently have a QVTO file and a Java blackbox unit (registered with extension point org.eclipse.m2m.qvt.oml.javaBlackboxUnits). The blackbox unit has been working. So has the QVTO file.

I have added a new method to the Java blackbox unit with this method signature:

@Operation(contextual = true, kind = Operation.Kind.HELPER)
public static void setSchemaForSchema(final XSDSchema self, final String prefix, final String namespace) { .... }

I added the following line to my QVTO file:

modeltype XSD uses 'http://www.eclipse.org/xsd/2002/XSD';

Now the blackbox fails to load and I get the following error in my error log:

Can't resolve 'interface org.eclipse.xsd.XSDSchema' as OCL type in java method 'public static void my.Blackbox.setSchemaForSchema(org.eclipse.xsd.XSDSchema,java.lang.String,java.lang.String)'

Am I using the wrong modeltype declaration? I can't seem to find another that would make sense.

Thanks in advance for the help,
---Tim---

Never mind. I figured out what was missing. I need to declare the metamodel nsURI as http://www.eclipse.org/xsd/2002/XSD in the org.eclipse.m2m.qvt.oml.javaBlackboxUnits.
