Ilan Kirsh commented on JDO-472:
--------------------------------

Unfortunately I am getting the same problems now with DocumentBuilder. I tried also the 3 previous versions of the xsd - and the result is the same. I am using JDK 1.5.0_09.

e.g.

org.xml.sax.SAXParseException: cos-nonambig: "http://java.sun.com/xml/ns/jdo/jdo":extension and "http://java.sun.com/xml/ns/jdo/jdo":extension (or elements from their substitution group) violate "Unique Particle Attribution". During validation against this schema, ambiguity would be created for those two particles.

> I am trying to use the last JDO 2.0 xsd with:
> SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
> URL xsdURL = getClass().getResource("/jdo_2.0.xsd");
> Schema schema = factory.newSchema(xsdURL);
> First I got the following exception (from newSchema):
> org.xml.sax.SAXParseException: cos-nonambig: "http://java.sun.com/xml/ns/jdo/jdo":extension and "http://java.sun.com/xml/ns/jdo/jdo":extension (or elements from their substitution group) violate "Unique Particle Attribution". During validation against this schema, ambiguity would be created for those two particles.
> And after trying to fix it, I got the following exception (from newSchema):
> org.xml.sax.SAXParseException: src-resolve.4.2: Error resolving component 'xs:attlist.jdo'. It was detected that 'xs:attlist.jdo' is in namespace 'http://www.w3.org/2001/XMLSchema', but components from this namespace are not referenceable from schema document 'file:/D:/odb/dv/rt/class/jdo.xsd'. If this is the incorrect namespace, perhaps the prefix of 'xs:attlist.jdo' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:/D:/odb/dv/rt/class/jdo.xsd'.
> The same 3 lines work well with JPA 1.0 xsd. Has anyone used JDO 2.0 xsd successfully already?
