Well, we started from scratch, fetched everything from SVN and executed the
steps you've mentioned above. I don't know what might have gone wrong. Here
are the contents of the ant folder (time is EEST):

The ant scripts have been updated (see above), so we should look for a fix
elsewhere...

Yes, I think so. We had:

component.ma.xmldb.db_uri=http://selena.acad.bg:8680/exist/rest/db/rrdmaconfig

and

component.ma.xmldb.db_uri.xmlrpc=http://selena.acad.bg:8680/exist/xmlrpc/db/rrdmaconfig

We tried to put the same value as in the later in the former, but it didn't
work that way either.

Kind regards,
Nina
