Start Unmarshaller setvalidating

Unmarshaller setvalidating

JAXB defines an architecture for binding XML schemata to Java objects.

As I understand it, the call to set Validating is deprecated in JAXB 2.0 and I should use set Schema. If so, how can I have my Validating JAXBContext class create an appropriate validation.

I've been looking for solutions to this problem for far too long considering how easy it sounds so I've come for some help.

Rather than creating a general validating mechanism it might be better to have a general mechanism you inherit from for specific validating purposes i.e. Our Validation Event Collector throws an unchecked exception (JAXBParser Exception) which we then handle with Exception Mapper. Hi Andrew, Validating is indeed deprecated and you need to set the Schema object to validate against.

JAXB_FORMATTED_OUTPUT, true); Schema(Schema Instance( XMLConstants. W3C_XML_SCHEMA_NS_URI)Schema( new File("students.xsd"))); marshaller.marshal(students, new File("a.xml"));[sax. SAXParse Exception: cvc-complex-type.2.4.b: The content of element 'ns2:students' is not complete. Marshaller Impl.write(Unknown Source) at xml.v2.runtime. Marshaller Impl.marshal(Unknown Source) at bind.helpers.

JAXB does this by specifying a binding between an XML document and Java Beans technology components, based on the XML document's XSD schema.

This makes it easy to read in different types of documents without knowing their type in advance. JAXBContext jaxb Context = Instance(package Name); Unmarshaller unmarshaller = jaxb Context.create Unmarshaller(); Validating(true); Item item = (Item) unmarshaller.unmarshal(new File("item.xml")); ...
