Thanks Keith.
Here's a simple test case that I believe should fail when unmarshalled by
Castor, but doesn't.
fruitbowl.xsd
==========
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.xxx.yyy/ns/food";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns="http://www.xxx.yyy/ns/food";
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xsd:element name="fruitbowl">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="banana" type="xsd:string"/>
<xsd:element name="pineapple" type="xsd:string"
minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
fruitbowl.xml
==========
<?xml version="1.0"?>
<fruitbowl xmlns="http://www.xxx.yyy/ns/food";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.xxx.yyy/ns/food fruitbowl.xsd">
<!--- <banana>Boris</banana> Yes, we have no bananas..... and therefore
should fail -->
<pineapple>Peter</pineapple>
</fruitbowl>
Performed a default unmarshalling ( no mapping file, no pre-generated
descriptors ) using Castor:
xml = new InputStreamReader( getClass().getResourceAsStream( "/" +
FRUITBOWL_XML ) );
Unmarshaller unmar = new Unmarshaller( new FruitBowl().getClass(),
Unmarshaller.class.getClassLoader() );
unmar.setValidation( true );
FruitBowl fb = (FruitBowl) unmar.unmarshal( xml );
and got a NULL banana as expected, but where's my Schema validation exception.
Performed a parsing of the same file using the Xerces SAXParser:
xml = new InputStreamReader( getClass().getResourceAsStream( "/" +
FRUITBOWL_XML ) );
org.xml.sax.XMLReader parser = (org.xml.sax.XMLReader) new
org.apache.xerces.parsers.SAXParser();
parser.setErrorHandler( new cHandler() );
parser.setFeature( "http://xml.org/sax/features/validation";, true );
parser.setFeature( "http://xml.org/sax/features/namespaces";, true );
parser.setFeature( "http://apache.org/xml/features/validation/schema";,
true );
parser.setFeature( "
http://apache.org/xml/features/validation/schema-full-checking";, true );
parser.parse( new InputSource( xml ) );
and got the following exception as expected:
The content of element type "fruitbowl" must match "(banana,pineapple?)
Is the difference in behaviour due to Castor using the SAX 1 org.xml.sax.Parser
interface rather than the SAX 2 org.xml.sax.XMLReader interface ?
I've tried the following and again received no validation exception:
xml = new InputStreamReader( getClass().getResourceAsStream( "/" +
FRUITBOWL_XML ) );
org.xml.sax.Parser parser = (org.xml.sax.Parser) new
org.apache.xerces.parsers.SAXParser();
parser.setErrorHandler( new eHandler() );
parser.parse( new InputSource( xml ) );
Can I conclude that in order to receive Schema validation exceptions, Castor
would have to be changed to use the SAX 2 XMLReader interface ?
Thanks for any help,
Gary
