Validating xml against xsd in java

// create Marshaller using JAXB context Marshaller m = context.create Marshaller(); // To format the [to be]generated XML output Property(Marshaller. TRUE); //Set Schema Schema( schema ); // Marshall the mapped object and write output to [or to a file] m.marshal(university, System.out); m.marshal(university, new File(SOME_FILE)); package com.model; import sax. In case the generated XML does not comply with specified schema , Marshaller/Validator will throw error and eventually fail.In our example, section property in Student class contains a min Length (4) constraints.Please note that Section element in below XSD contains a min Length constraint(4 chars).We will verify the validation against this constraint. SAXParse Exception; public class Custom Validation Error Handler implements Error Handler That’s it.The schema is the specification for how our XML may look like. Java merely provides a mechanism of validation the schema rules against a given XML.
