JAXB 2.0 validation when marshalling

Question

Hi,
I'm using JAXB to marshall and unmarshall files. The issue i'm trying to address is that when a file is being marshalled - if a value is mandatory in the schema and if the user provides null value or something then shoulding this be a validation error? I dont get any notification even if I have attached a validationhandler to my marshaller and the file is created with that particular value blank.... so anyone has any idea of how we can validate the documents created by JAXB that they're valid.
thanks
SA

Ok i figured out one way of doing this by using some classes from JAXP...
SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema s = null;
try{
    s = sf.newSchema(new File("Sources/schema/test.xsd"));                    
}catch(Exception e){
    System.err.println("Exception e: " + e.getMessage());
marshaller.setSchema(s);
//MyValidationHandler class implements the ValidationEventHandler interface
MyValidationHandler gv = new MyValidationHandler();
marshaller.setEventHandler(gv);If anyone has something to add let me know!!
