Hi, I have certain report units that fail with the message "java.lang.Exception: 1 - org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'jasperReport'. The reports that work use the DTD, the ones that don't use the new version with XSD. The reports run in iReport 3.1.2NB, just not on Jasper Server 3.0. Do you have any idea what causes this? I was wondering whether it was the namespace in the xml and it possibly not finding the xsd to validate. I've included the jasperReport tag out of the xml for reference. Thanks, Mark.
