Michael Glavassevich resolved XERCESJ-1739.
-------------------------------------------
Resolution: Invalid
This is working as designed. The JAXP spec requires this behaviour. If you want
XML schema documents to be loaded from xsi:schemaLocation attributes in the
instance document, you need to use this method:
https://xerces.apache.org/xerces2-j/javadocs/api/javax/xml/validation/SchemaFactory.html#newSchema()
instead for creating the Schema object.

> Key: XERCESJ-1739
> URL: https://issues.apache.org/jira/browse/XERCESJ-1739
> Project: Xerces2-J
> Issue Type: Bug
> Components: JAXP (javax.xml.validation)
> Affects Versions: 2.12.1
> Reporter: Yasir Bajwa
> Priority: Minor
>
> setEntityResolver on SAXParser is not being called to resolve
> xsi:schemaLocation.
> Example:
> class DummyResolver implements EntityResolver {
> @Override
> public InputSource resolveEntity(String publicId, String
> systemId) throws SAXException
> { throw new SAXException("Access denied."); }
> }
> // main()
> // Path schemaPath ...
> // Path dataPath ...
> SchemaFactory schemaFactory = SchemaFactory.newInstance(
> "[http://www.w3.org/XML/XMLSchema/v1.1]";);
> StreamSource schemaSource = new StreamSource(schemaPath.toFile());
> Schema schema = schemaFactory.newSchema(schemaSource);
> SAXParserFactory spf = SAXParserFactory.newInstance();
> spf.setSchema(schema);
> spf.setNamespaceAware(true);
> SAXParser sp = spf.newSAXParser();
>
> XMLReader parser = sp.getXMLReader();
> //parser.setErrorHandler(new SAXErrorHandler());
> //parser.setContentHandler(new TestHandler());
> parser.setEntityResolver( new DummyResolver());
> InputSource is = new InputSource(new
> FileInputStream(dataPath.toFile()));
> parser.parse(is);
>
> Schema (i.e. the file 'schemaPath' variable references in the code above)

> Result:
> Exception in thread "main" org.xml.sax.SAXException: Error:
> URI=[[file:///C:/tpon/fod/schema/xerces_tests/test1/input.xml]] Line=12:
> cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration
> can be found for element 'fod:testElement'.
>
> Expected result was for xsi:schemaLocation to try resolve the fod namespace
> and call entity resolver to get the fod.xsd schema docment.
