Schema validation ( and my pain in the u know what)

[motoman]

i have the following code (see below), i run my validation and get
unexpected results.

Public ID: null
System ID: file:///C:/DATA/Sandpit/Eclipse/workspace/dtdValidation/memory.xml
Line number: 4
Column number: 44
Message: Element type "memories" must be declared.

Public ID: null
System ID: file:///C:/DATA/Sandpit/Eclipse/workspace/dtdValidation/memory.xml
Line number: 5
Column number: 24
Message: Element type "memory" must be declared.

and so on for almost every element in the XML where i should be
getting real schema errors eg.

Public ID: null
System ID: file:///D:/herong/dictionary_invalid_xsd.xml
Line number: 7
Column number: 22
Message: cvc-datatype-valid.1.2.1: 'yes' is not a valid 'boolean'
value.
...............

To me it looks like the validation is not actually picking up the
schema, does this sound right?. The schema and xml are both in the
same directory. Can someone give me some ideas on the possible source
of the problem.
I have been looking at previous posts on this forum and nobody seems
to be getting an answer. Please help i am despirate here, my deadline
date is approaching fast.
class validation {

public static StringBuffer sErrorBuffer = new StringBuffer();

XMLReader r = XMLReaderFactory.createXMLReader(parserClass);
r.setFeature(validationFeature,true);
r.setFeature(schemaFeature,true);
r.setErrorHandler(new MyErrorHandler());
r.parse("memory.xml");

System.out.println(sErrorBuffer.toString());

System.out.println("So many errors so little time");

} catch (SAXException e) {
System.out.println(e.toString());

e.printStackTrace();
}
}

sErrorBuffer.append("\n Column number: "+e.getColumnNumber());
sErrorBuffer.append("\n Message: "+e.getMessage() + "\n");
