I am having basically the same problem, with the exception that I am using the DocumentBuilder so I can create DOM trees. As far as I can tell, there is no setProperty method, so I cannot use this fix to at least get *somewhere*.
Regardless if this hack clears up the symptoms or not, I do not accept this as a valid fix. The fact remains that referencing an namespace-using schema in a normal document-based manor causes the schema not to be processed correctly. My test example that does not work is as follows:
Schema:
<?xml version="1.0" encoding="UTF-8"?> <xsd:schema targetNamespace="http://schemas.gridforum.org/gridServices/rsl"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:rsl="http://schemas.gridforum.org/gridServices/rsl"; xmlns="http://schemas.gridforum.org/gridServices/rsl"; version="0.2">
<xsd:element name="rsl" type="rslType"/>
<xsd:complexType name="rslType">
<xsd:sequence>
<xsd:element name="job" type="xsd:string" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType></xsd:schema>
Document:
<?xml version="1.0" encoding="UTF-8"?>
<rsl
xmlns:rsl="http://schemas.gridforum.org/gridServices/rsl";
xmlns="http://schemas.gridforum.org/gridServices/rsl";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="
http://schemas.gridforum.org/gridServices/rsl
schema/test.xsd">
<job> Jobby Job Job </job>
</rsl>
Xerces code:
DocumentBuilder xmlParser = null;
try {
parserFactory = DocumentBuilderFactory.newInstance();
parserFactory.setNamespaceAware(true);
parserFactory.setValidating(true);
xmlParser = parserFactory.newDocumentBuilder();
xmlParser.setErrorHandler(this);
} catch (javax.xml.parsers.ParserConfigurationException pce) {
logger.error("problem getting parser factory instance", pce);
return null;
} BufferedReader bufferedReader = new BufferedReader(xmlReader);
return xmlParser.parse(new InputSource(bufferedReader));I would really appreciate any help on this since my project is essentially stalled until I get this working.
Thanks, Peter

Hi!
Finally, I found a way to get it work. By setting the namespace-feature to true and setting the XSD definition with the http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation property, the parser actually validates using my schema defintion.
Thanx for your efforts.

Have you tried turning on namespace? (SAXParserFactory#setNamespaceAware)

still unable to validate against XSD 10/07/2002 06:04 AM

Hi there!
I'm still unable to validate my xml file against an XSD. Here ist the code, I use to load the file via SAX, using XERCES 2.0 (JRE1.3.1):
private static final String FLAG_VALIDATE = "http://xml.org/sax/features/validation";; private static final String FLAG_SCHEMA = "http://apache.org/xml/features/validation/schema";;
private SAXParserFactory factory = null; private org.xml.sax.SAXParser saxParser = null;
... factory = SAXParserFactory.newInstance(); ... saxParser = factory.newSAXParser(); ... saxParser.getXMLReader().setFeature(FLAG_VALIDATE, true); saxParser.getXMLReader().setFeature(FLAG_SCHEMA, true); saxParser.parse(new File(file), this); ...
This always gives me an error saying "cvc-elt.1: Cannot find the declaration of element 'whatever'".
Since then, I've tried to use an EntityResolver for loading the XSD. I've started with writing a little test code for the EntryResolver like this:
public class SAXEntityResolver implements EntityResolver {
public InputSource resolveEntity(String publicID, String systemID) throws SAXException, IOException { System.out.println(publicID+", "+systemID); return null; }
}
...
private static final String FLAG_VALIDATE = "http://xml.org/sax/features/validation";; private static final String FLAG_SCHEMA = "http://apache.org/xml/features/validation/schema";;
private SAXParserFactory factory = null; private SAXParser saxParser = null;
... factory = SAXParserFactory.newInstance(); ... saxParser = factory.newSAXParser(); ... saxParser.getXMLReader().setFeature(FLAG_VALIDATE, true); saxParser.getXMLReader().setFeature(FLAG_SCHEMA, true); saxParser.getXMLReader().setEntityResolver(new SAXEntityResolver()); saxParser.parse(new File(file), this); ...
In result, my programm still reads the xml file with the same error as before. The println() in the EntityResolver is never reached.
I woulde really appreciate any help on this. Next on schedule is testing and I'm still unable to validate the xml file. Btw., loading the file with any other XML/XSD aware application works fine.
regards Heiner
