[jira] Updated: (XERCESJ-1101) Validating DocumentBuilder instance
fails to parse more than one XML document.
[ http://issues.apache.org/jira/browse/XERCESJ-1101?page=all ]
Michael Glavassevich updated XERCESJ-1101:
------------------------------------------
Fix Version: 2.8.0
Description:
When DocumentBuilder instance with W3C XML Schema validation is created using JAXP 1.2 and is used for parsing it fails on second XML document.
Here is sample code snippet:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating(true);
Object[] schemaSource = new Object[] {
// it is important to pass schemas as InputStreams to prevent schemas reparsing
ParsingTest.class.getResourceAsStream("ParsingTest.xsd"),
};
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource", schemaSource);
DocumentBuilder documentBuilder = factory.newDocumentBuilder();
documentBuilder.setErrorHandler(...);
documentBuilder.parse(new FileInputStream("C:\\ParsingTest.xml"));
System.out.println("OK");
documentBuilder.parse(new FileInputStream("C:\\ParsingTest.xml"));
System.out.println("OK");
When this code is run it throws this exception:
Exception in thread "main" org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'A'.

This code fail on Xerces 2.7.0 and 2.7.1. It works on Xerces 2.2.1, 2.3.0, 2.4.0, 2.5.0, 2.6.0, 2.6.1 and 2.6.2. It also works on jaxp 1.2.2, jaxp 1.3.1 and JDK 1.5.
This issue is very important for us because new validation API doesn't meet our performance requirements and requires JAXP 1.3 compatible parser (is less portable).
