I have no idea how to reference a file from the root directory. Currently, any path in the URI is child of the user directory. I'm trying to access /var/www with this:
sftp://user:password@host/var/www
but it's ineffective.
org.apache.commons.vfs2.FileNotFolderException: Could not list the contents of "sftp://user:***@host/var/www" because it is not a folder.
