> gnu.xml.aelfred2.JAXPFactory This is the most likely cause of the problem. This SAX parser is not part of standard Java runtime libraries, afaik. So I am assuming that the execution classpath have explicitly included this library. I would suggest you remove this library from classpath. Java runtime libraries come with default SAX parsers and they should be sufficient for OpenJPA to parse the XML files it needs to.
