Question JAXB 2.0 ValidationEventHandler

Hi,

I am unmarshalling an xml using JAXB 2.0 as below:

JAXBContext jaxbContext = JAXBContext.newInstance("mypackage");
			Unmarshaller unMarshaller = jaxbContext.createUnmarshaller();
	        SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema"); 
	        Schema schema = schemaFactory.newSchema(new File("schemaxsd")); 
			unMarshaller.setSchema(schema);
			unMarshaller.setEventHandler(
                    new ValidationEventHandler() {
                        // allow unmarshalling to continue even if there are errors
                        public boolean handleEvent(ValidationEvent ve) {
                            // ignore warnings
                            if (ve.getSeverity() != ValidationEvent.WARNING) {
                                ValidationEventLocator vel = ve.getLocator();
                                System.out.println("Line:Col[" + vel.getLineNumber() +
                                    ":" + vel.getColumnNumber() +
                                    "]:" + ve.getMessage());
                            }
                            return true;
                        }
                    }
                );				        
			JAXBElement<CatalogType> catalogElement = (JAXBElement<CatalogType>) unMarshaller.unmarshal(xmlDocument);

If the input xml is invalid it shows the exception message saying:

This exception says that the name element is not expected which is fine. If this is the case then i need to the parent node of the element where the exception occurred and should perform some business logic. I am not able to get the parent node. I tried this:

but, I get null. How do i get the parent node?

Could anyone please help me out.

Thanks,

Hi Sukumar Gaade,

I have the same problem? Have you solved it?

You need to use a different method and supply the class you expect.

If the input xml is invalid it shows the exception message saying:
Invalid content was found starting with element 'name'. No child element is expected at this point.

This exception says that the name element is not expected which is fine. If this is the case then i need to the parent node of the element where the exception occurred and should perform some business logic. I am not able to get the parent node. I tried this:
validationEvent.getLocator().getNode();
but, I get null. How do i get the parent node?

Could anyone please help me out.
