Hi,
>From a quick glance at the code, it looks like Digester registers itself
as an org.xml.sax.ErrorHandler (it extends
org.xml.sax.helpers.DefaultHandler), and that by default it ignores all
sax errors:
public void error(SAXParseException exception) throws SAXException {
log.error("Parse Error at line " + exception.getLineNumber() +
" column " + exception.getColumnNumber() + ": " +
exception.getMessage(), exception);
if (errorHandler != null) {
errorHandler.error(exception);
}
}
Craig/Robert: why does Digester ignore sax errors by default?
ldewavrin: you can provide an ErrorHandler which Digester will delegate
to. So I suggest you write a subclass of org.xml.sax.ErrorHandler which
always rethrows the input exception and register it with the Digester
using:
digester.setErrorHandler(errorHandler).
Hopefully this will resolve your issue...

Simon
