How to validate an XML against schema using JAXB?

Question

I am working with XML and JAXB as I am unmarshalling and marshalling the XML into Java objects and vice versa. Now I am trying to validate our XML

Answer 1

You just need to set an instance of javax.xml.validation.Schema on the Unmarshaller before you do the unmarshal. You can specify an implementation of ValidationEventHandler on the Unmarshaller to catch any problems that occur during the unmarshal process.
