Hi,
I have to validate a SAX-stream against a XML-Schema. My plan was to
implement a custom ContentHandler which sends all SAX-events to the
parser. Therefore I used an instance of
org.apache.xerces.parsers.SAXParser, because this class implements alls
SAX-events.
So I created an SAXParser and set the following features and properties:
SAXParser parser = new SAXParser();
parser.setFeature("http://xml.org/sax/features/validation";, true);
parser.setFeature("http://apache.org/xml/features/validation/schema";,
true);
parser.setFeature("http://xml.org/sax/features/namespace-prefixes",true);
parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking",true);
parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation";,
"schema.xsd");
parser.setErrorHandler(handler);
The ErrorHandler is a custom one that throws exceptions in every case.
Then I implemented start-/endDocument and start-/endElement of my
DocumentHandler. In this methods I called:
parser.startElement(...), parser.endElement(...)....
So far so good (I hope). Then I started testing and debugging. I know,
that the parser-methods are called. But I have a Problem with the
http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation-property.
The argument doesn't seem to have any influence to the parser. I can
put every argument a want and never get an exception. I can even put an
Boolean-object there!
I tried debugging, but I didn't have any success.
Within a fex minutes I will put the source-code of my ContentHandler on:

I hope, you can give me some hints! Thank you very much.
Best regards
Volker
