Thanks for the replies: Just setting validation and schema validation to true did not accomplish what I needed it to do. I still was unable to access the parser to set the properties needed. I ended up cloning UnmarshallerImpl and making the getParser() method public (rather than package private) to do what I needed it to. | 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", (String)null); | stream.close(); | binding.setStrictSchema(true); | UnmarshallerImpl unmarshaller = new UnmarshallerImpl(); | String schemaLocation = new File("/home/rob/apps/eclipse/workspaces/work/garbage/src/schema.xsd").toURI().toURL().toExternalForm(); | unmarshaller.setValidation(true); | unmarshaller.getParser().setFeature("http://apache.org/xml/features/...;, true); | unmarshaller.getParser().setProperty("http://apache.org/xml/properti...;, | schemaLocation); | 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!"); | } | } | Now I'm just looking via APIs to find a similar way to enforce strict validation when writing / marshalling the files as well ;) Again, thanks for the help.
