Today , I use
exportDocumentView and session.importXML method to realize
backup and restore data (primary for users and groups) for jackrabbit ,
however , I found javax.jcr.nodetype.ConstraintViolationException happened when
I try to restore data with the method importXML .
Is there any way to backup and restore data in
jackrabbit and I don't want to use other tool , can Jackrabbit do it ?
