Best way to validate and xml file against a schema?

Question

As the subject states, I want to validate my xml file against a given schema....
Currently my code looks like this:
InputSource ipSource = new InputSource(new ByteArrayInputStream(bytesData)); // my xml file
DOMParser parser = new DOMParser();
parser.parse(ipSource);
Document doc = parser.getDocument();
I see that there is a setFeature method on DomParser.... but from what I read that doesnt support
xml schema's, just DTD's. So what is the best way to validate with schema's?
Any help would be appreciated

Answer 1

This is the other way I tried doing it.... the problem with this way is I am building my xml file through DOM
operations... and I haven't figured out how to add the schema line to the xml file through DOM manipulations.
Has anyone done this bofore?
try
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
     factory.setNamespaceAware(false);
     factory.setValidating(true);
     InputSource ipSource = new InputSource(new ByteArrayInputStream(bytesData));
     DocumentBuilder builder = factory.newDocumentBuilder();
     doc      = builder.parse(ipSource);
     return doc;
catch(Throwable t)
     System.out.println("parse error: " +t);
return doc;
}
