Can you please help me to get the list of all errors when I validate the XML file using JAXB?
Right now I have already implemented the code for the same. I have implemented the code using unmarshalling the XML file.
When I unmarshalling the XML file at that time if any error would be there in the XML file, I got the exception but it came out after giving the first exception but I want the list of all errors of that XML file. This should not come out after getting the first error.
Source xsdFileName = new StreamSource(new File("validate6.xsd"));
Source xmlFileName = new StreamSource(new File("test3.xml"));
try {
SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = sf.newSchema(xsdFileName);
JAXBContext jc = JAXBContext.newInstance(Innovations.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
unmarshaller.setSchema(schema);
unmarshaller.setEventHandler(new MyValidationEventHandler());
Innovations innovation = (Innovations) unmarshaller.unmarshal(xmlFileName);
System.out.println("Total Size :: " + innovation.getInnovationList().size());
System.out.println(xmlFileName.getSystemId() + " is valid");
} catch (JAXBException e) {
e.printStackTrace();
System.out.println(xmlFileName.getSystemId() + " is NOT valid");
} catch (SAXParseException e) {
e.printStackTrace();
System.out.println(xmlFileName.getSystemId() + " is NOT valid");
} catch (SAXException e) {
e.printStackTrace();
System.out.println(xmlFileName.getSystemId() + " is NOT valid");
}

I guess a custom validator will help you:
and then
