Hi everyone,
my export/import method as follow:
/**
*
* @param path node path
* @param xmlfileName xml file name eg:"systemview.xml"
*/
public void exportData(final String path, final String xmlfileName){
jcrTemplate.execute(new JcrCallback(){
public Object doInJcr(Session session) throws IOException,
RepositoryException {
File outputFile = new File(xmlfileName);
FileOutputStream out = new FileOutputStream(outputFile);
session.exportSystemView(CMSUtil.normalizedPath(path), out,
false, false);
return null;
}
});
}
/**
*
* @param path node path
* @param xmlfileName xml file name eg:"systemview.xml"
*/
public void importData(final String path, final String xmlfileName){
jcrTemplate.execute(new JcrCallback(){
public Object doInJcr(Session session) throws IOException,
RepositoryException {
File inputFile = new File(xmlfileName);
FileInputStream in = new FileInputStream(inputFile);
session.importXML
(CMSUtil.normalizedPath(path), in,
ImportUUIDBehavior.IMPORT_UUID_CREATE_NEW);
return null;
}
});
jcrTemplate.save();
}
I do exportData("/","file.xml"), then changed the repository.xml of jackrabbit
1.6.2, (add datastore, change
org.apache.jackrabbit.core.persistence.db.SimpleDbPersistenceManager to
org.apache.jackrabbit.core.persistence.bundle.MySqlPersistenceManager ) and
drop the db tables jackrabbit use,( also the workspace.xml in repo home
directory). and I got follow error info when i importData("/", "file.xml").

I also tried create a new node "/test" in the jackrabbit root node, and
importData("/test", "file.xml"). get the follow error:
