I've been trying this out for a while... no success. Schema: <xsd:schema xmlns:jbxb="http://www.jboss.org/xml/ns/jbxb" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="garbageRoot" type="root-type"/> <xsd:complexType name="root-type"> <xsd:annotation> <xsd:appinfo> <jbxb:class impl="garbage.XbGarbageRoot"/> </xsd:appinfo> </xsd:annotation> <xsd:attribute name="name" type="xsd:string" use="required" /> </xsd:complexType> </xsd:schema> XbGarbageRoot (POJO): public class XbGarbageRoot { private String name; public XbGarbageRoot() { } public String getName() { return name; } public void setName(String name) { this.name = name; } } Test case: public class ParseTest extends TestCase { private static final String SCHEMA = "/home/rob/apps/eclipse/workspaces/work/garbage/src/schema.xsd"; private static final String DATA = "/home/rob/apps/eclipse/workspaces/work/garbage/data/test.xml"; public void testABC() { try { File f = new File(SCHEMA); InputStream stream = new FileInputStream(f); SchemaBinding binding = XsdBinder.bind(stream, "UTF-8", null); stream.close(); Unmarshaller unmarshaller = UnmarshallerFactory.newInstance().newUnmarshaller(); binding.setStrictSchema(true); FileInputStream dataStream = new FileInputStream(new File(DATA)); Object xmlObject = unmarshaller.unmarshal(dataStream, binding); System.out.println("object is " + xmlObject); } catch( Exception e ) { // GOOD! I want XB to fail! return; } fail("data file should not have validated!"); } } Clearly, i'm setting that it should use a strict schema... but it's not throwing an exception. Any ideas?
