JAXB and EntityResolver

Question

Ok so here is the deal. I have an xml file starting like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:rosApplicationDocument xmlns:ns2="http://ereg.egov.bg/segment/0009-000013" xmlns:ns3="http://ereg.egov.bg/segment/0009-900001" xmlns:ns4="http://ereg.egov.bg/segment/0009-000022">

And the xsd starting like that:

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://ereg.egov.bg/segment/0009-900001" xmlns="http://ereg.egov.bg/segment/0009-900001"

    /> <xsd:field xpath="@ref"/> </xsd:keyref> -->

<xsd:element name="RosApplicationDocument" type="RosApplicationDocument" />

And the unmarshalling :

JAXBContext context = JAXBContext.newInstance(c);
            Unmarshaller um = context.createUnmarshaller();
            if (c.equals(RosApplicationDocument.class)) {
                SchemaFactory schemaFactory = SchemaFactory
                        .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
                Schema schema = schemaFactory.newSchema(new File(pathToXSD));
                um.setSchema(schema);
                RosApplicationDocument document = (RosApplicationDocument) um
                        .unmarshal(getSource(pathToFile));
                RosApplicationDocumentFactory.removeCDATAFromSegments(document);
                return document;
            }

public static SAXSource getSource(String pathToFile) {
        try {
            SAXParserFactory parserFactory = SAXParserFactory.newInstance();
            parserFactory.setNamespaceAware(true);
            parserFactory.setValidating(true);
            SAXParser saxParser = parserFactory.newSAXParser();
            XMLReader xmlReader = saxParser.getXMLReader();
            xmlReader
                    .setEntityResolver(new RosApplicationDocumentEntityResolver());
            InputSource inSrc = new InputSource(new FileReader(pathToFile));
            return new SAXSource(xmlReader, inSrc);
        } catch (SAXException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (ParserConfigurationException e) {
            e.printStackTrace();
        }

        return null;
    }

Why do i get this exception : [org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'ns3:rosApplicationDocument'.]

Edit:

Here is the LSResourceResolver:

public class MyLSResourceResolver implements LSResourceResolver {

    @Override
    public LSInput resolveResource(String type, String namespaceURI,
            String publicId, String systemId, String baseURI) {
        System.out.println(publicId);
        System.out.println(systemId);
        System.out.println(baseURI);
        System.out.println(namespaceURI);
        System.out.println(type);
        return null;
    }

}

i set it to the factory like : schemaFactory.setResourceResolver(new MyLSResourceResolver());

And here is the output of the console :

javax.xml.bind.MarshalException
 - with linked exception:
[org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'ns3:rosApplicationDocument'.]

The same exception at the end.. So the problem isnt in the xsd

Answer 1

In the xml you have:

xmlns:ns3="http://ereg.egov.bg/segment/0009-900001"

So http://ereg.egov.bg/segment/0009-900001 should be the default namespace of your schema, but I don't see it declared in the sample code that you posted.

Also, in the schema the element is declared RosApplicationDocument while in the document rosApplicationDocument (lower case)

Answer 2

Currently you are setting an Schema on the Unmarshaller to enable schema validation, and creating a SAXSource on a validation XMLReader that you are unmarshalling. As a first step I would recommend simplifying your code to simply do the following:

        JAXBContext context = JAXBContext.newInstance(c);
        Unmarshaller um = context.createUnmarshaller();
        if (c.equals(RosApplicationDocument.class)) {
            SchemaFactory schemaFactory = SchemaFactory
                    .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
            Schema schema = schemaFactory.newSchema(new File(pathToXSD));
            um.setSchema(schema);
            InputSource inSrc = new InputSource(new FileReader(pathToFile));
            RosApplicationDocument document = (RosApplicationDocument) um
                    .unmarshal(inSrc);
            RosApplicationDocumentFactory.removeCDATAFromSegments(document);
            return document;
        }
