If it worked, then the schema must have been originally defined with no targetNamespace attribute, so you must have changed the schema. Then you say if you were setting the property in the instance document, you would give a different URI for the location. I'm confused. Maybe you have your examples mixed up.
First off, did you try to specify the schema location in the document? We know unequivocally that the URI in the document must be relative to the document, per your last example. Does that work? Trying that will at least produce an error message that differentiates between not being able to find the schema and not finding the element decl in the schema.

Hi,
Michael, thankyou very much for your help. I was indeed missing the namespace part of the property. This has fixed one error, but the second remains:
Illegal XML: cvc-elt.1: Cannot find the declaration of element 'Root'.
Again, it seems to me that either the schema can't be found or the Root element can't be matched against the one defined in the schema.
My schema is now:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; version="0.9" targetNamespace="http://www.mynamespace.com";
xmlns="http://www.mynamespace.com";
elementFormDefault="qualified">
<xs:element name="Root"> <xs:complexType> blah...
My instance document begins:
<Root xmlns="http://www.mynamespace.com";> <blah>
And my code reads:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); *if*(schemaLocation != *null*) {
factory.setNamespaceAware(*true*);
factory.setValidating(*true*);
factory.setAttribute("http://apache.org/xml/features/validation/schema";, Boolean.TRUE);
factory.setAttribute("http://apache.org/xml/properties/dom/document-class-name";, "org.apache.xerces.dom.PSVIDocumentImpl");
factory.setAttribute("http://apache.org/xml/properties/schema/external-schemaLocation";, schemaLocation);
}
Where schemaLocation is "http://www.mynamespace.com conf/BDM-FDDNUServletRequest.xsd"
The schema location worked when I set it as the value of the property "http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation";, so presumably the parser's still finding the schema.
If I was specifiying a schema within an instance document I'd use something like this:
<Root xmlns="http://www.mynamespace.com"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.mynamespace.com FormsSchema.xsd">
Does setting the "external-schemaLocation" property on Xerces avoid the need for me to have to set the second of these three properties?
What final connecting element am I still missing?
Thanks again for your time,
John
