Pierpaolo,
Are you on Java 1.4.2 or V1.5?
I had a similar error when running on 1.4.2 if I did not endorse the
Xerces and JAXP libraries.

As a couple of dozen of million users, I need to validate an xml

The (relevant portion of the) XML schema follows:

xsi:schemaLocation=
"http://www.med.univaq.it/vittorini/xdtfnse
xdtfnse.xsd">
... CONTENT ...
</xdtfnse>
Therefore, I wrote a validator in Java (Xerces is
xercesImpl-2.8.1.jar):
try {
SchemaFactory factory =
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new File("xdtfnse.xsd"));
Validator validator = schema.newValidator();
DocumentBuilder parser =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = parser.parse(new File("doc.xml"));
validator.validate(new DOMSource(document));
} catch (Exception e) {
e.printStackTrace();
}
Unfortunately, when I try to validate the above XML document
against the
Schema, I get the following error:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the
declaration of
element 'xdtfnse'.
Question is: wrong namespace? namespace not correctly specified?
After several long searches in the web, I could not find any solution.
Please help me or please let me know where to find an answer.
Kind regards and please apologize if this question already appeared
in the
mailing list, but -- again -- all I found/read about this problem
didn't
suffice.
