[jboss-dev-forums] [Design of JBossXB] - Re: How to force strict validation?

[alex.loubyansky@jboss.com]

W/o changing APIs you could do something like this:
      final String xsd =
  |          "<xsd:schema" +
  |          " xmlns:jbxb='http://www.jboss.org/xml/ns/jbxb'" +
  |          " xmlns:xsd='http://www.w3.org/2001/XMLSchema'>" +
  |          " <xsd:element name='root' type='root-type'/>" +
  |          " <xsd:complexType name='root-type'>" +
  |          "   <xsd:annotation>" +
  |          "     <xsd:appinfo>" +
  |          "       <jbxb:class impl='" + E.class.getName() + "'/>" +
  |          "     </xsd:appinfo>" +
  |          "   </xsd:annotation>" +
  |          "   <xsd:attribute name='unqualified' type='xsd:string' use='required'/>" +
  |          " </xsd:complexType>" +
  |          "</xsd:schema>";
  | 
  |       String xml = "<root xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='testns'/>";
  | 
  |       org.xml.sax.EntityResolver resolver = new org.xml.sax.EntityResolver()
  |       {
  |          public InputSource resolveEntity(String publicId, String systemId) throws SAXException, IOException
  |          {
  |             if(systemId != null && systemId.endsWith("testns"))
  |                return new org.xml.sax.InputSource(new StringReader(xsd));
  |             return null;
  |          }
  |       };
  | 
  | /*
  |       Validator.assertValidXml(xml, new org.xml.sax.EntityResolver()
  |       {
  |          public InputSource resolveEntity(String publicId, String systemId) throws SAXException, IOException
  |          {
  |             if(systemId != null && systemId.endsWith("testns"))
  |                return new org.xml.sax.InputSource(new StringReader(xsd));
  |             return null;
  |          }
  |       });
  | */      
  | 
  |       SchemaBinding schema = XsdBinder.bind(new StringReader(xsd), null);
  |       Unmarshaller unmarshaller = UnmarshallerFactory.newInstance().newUnmarshaller();
  |       unmarshaller.setEntityResolver(resolver);
  |       unmarshaller.setSchemaValidation(true);
  | 
  |       Object o = unmarshaller.unmarshal(new StringReader(xml), schema);
  |       assertTrue(o instanceof E);

This will throw the exception you expect. The difference is that I had to add noNamespaceSchemaLocation into the xml instead of setting it on the parser.
It might still be useful to expose setProperty() or the parser itself though.
