It may be that parser can not locate schema of xml you're parsing. Make sure you have schema specified either in xml file itself or using one of the properties available. Andrea Bigger wrote: Hi. In the W3C Recommendation I found following statement: << [...].

I'm currently using JDOM v1.0b8 on top of Xerces-J v2.4.0 and every time I try to get a value of an unset attribute/value which should have a fixed value, I get a null reference. JDOM uses a org.apache.xerces.parsers.SAXParser, validation is enabled and feature http://apache.org.xml.features/validation/schema is true. The schema processor seams not to work properly. What could be wrong? Thanks for help/hints.
