Re: [Exist-open] Change ownership

[Joe W. <jo...@gm...>]

Hi Nicolas,

Craig's query will work if you have the shared-resources package installed,
but if not (it is no longer included in eXist releases), you will receive
an error:

> Cannot compile xquery: err:XQST0059 error found while loading module
dbutil: failed to load module: 'http://exist-db.org/xquery/dbutil' from: '
http://exist-db.org/xquery/dbutil', location: '
http://exist-db.org/xquery/dbutil'. Source not found.

The solution is either to install the shared-resources package via
Dashboard > Package Manager, or to use eXide's bundled version, by changing
the module import declaration to:

import module namespace dbutil="http://exist-db.org/xquery/dbutil" at
"/db/apps/eXide/modules/dbutils.xqm";
