Hi,
I finally managed to detect the problem of the java.lang.ClassCastException:
I have a regular startElement method in my handler class:
public void startElement(String namespaceURI,
String sName, // simple name (localName)
String qName, // qualified name
Attributes attrs)
throws SAXException
{
I need to check the attributes and if necessary change an attribute.
So in this method I call a private method:
this.checkFileRelatedAttributes((org.xml.sax.helpers.AttributesImpl) attrs);
I cast the attrs to a AttributesImpl class because with this class I can
easily replace an attribute using the setAttribute method.
The moment the checkFileRelatedAttributes method is called the
java.lang.ClassCastException is thrown.
I have no idea why this happens or how to solve this.
Any help/hints are welcome to find a solution.
Please note that this does work under Xalan 22D14, but not with a later
version.
Regards,
Stefan
