I'm trying to parse and validate a XML document against a schema with JDOM and Xerces.

I obtain this error:

org.jdom.JDOMException: Error on line 6 of document file:///E:/developpement/SitePerso/xml/xml/listeEntreprises.xml: cvc-complex-type.2.4.a: Invalid content starting with element 'item'. The content must match '(("":nom){0-1},("":item){0-UNBOUNDED})'.

Does someone understand what does it mean ?

Thank you
