Question

How can I validate enum values with XSD in JAXB? I would like to throw an error if a bad value was set but missing value is good (minOccurs = "0" ).

The solution:

    SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = sf.newSchema(this.getClass().getClassLoader().getResource("XSD FILE UNDER WEB-INF/classes"));
    unmarshaller.setSchema(schema);
