Originally reported on java.net, jaxp issue 30:
I have an application where xml streams needs to be validated against xsd-schemas.
Using JDK 1.5 (jdk1.5.0_07) this works well and the streams are correctly validated.

When I use Java 1.6 (build 1.6.0-b105) the minOccurs and maxOccurs seams to be
skipped from the validation process and the xml is always reported as valid.

Here is a snippet of my code:

File xmlFile = new File("occurs.xml");

SchemaFactory factory=SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new File("occurs.xsd"));

// get a DOM factory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
// configure the factory
dbf.setNamespaceAware(true);

// set schema on the factory
dbf.setSchema(schema);

DocumentBuilder documentBuilder = dbf.newDocumentBuilder();

// Check the document
try {
documentBuilder.parse(xmlFile);
System.out.println(xmlFile.getName() + " is valid.");
}
catch (SAXException ex) {
System.out.println(xmlFile.getName() + " is not valid because ");
System.out.println(ex.getMessage());
}

// And the corresponding xml and xsd.

occurs.xml

<?xml version="1.0" encoding="ISO-8859-1"?>
 
<persons>
 
<person>
<full_name>Hege Refsnes</full_name>
<child_name>Cecilie</child_name>
</person>
 
<person>
<full_name>Tove Refsnes</full_name>
<child_name>Hege</child_name>
<child_name>Stale</child_name>
<child_name>Jim</child_name>
<child_name>Borge</child_name>
</person>
 
<person>
<full_name>Stale Refsnes</full_name>
</person>
 
</persons>




occurs.xsd

<?xml version="1.0" encoding="ISO-8859-1"?>

Java 1.5 reports:
occurs.xml is not valid because
cvc-complex-type.2.4.d: Invalid content was found starting with element
'child_name'. No child element is expected at this point.

while Java 1.6 reports:
occurs.xml is valid.

I browsed the JAXP Project Page to find the differences from JAXP 1.3 is
included in J2SE 5.0 and the implementation of JAXP 1.4 is part of Java SE 6.0
but found nothing linked to my problem.
