I tried to narrow it down but it's still strange: The exact same code works when using "ftp://"; but does not work with "sftp://"; in the setVfsRoot() methode. With "sftp://"; I get an error like:
org.apache.ftpserver.ftplet.FtpException: Error resolving home directory / of user demo. at org.vfsutils.ftpserver.filesystem.VfsFileSystemFactory.createFileSystemView(VfsFileSystemFactory.java:64) ~[vfsutils-ftpserver-0.2.0-SNAPSHOT.jar:na] The demo user is the login for the local ftp server. Why does it use the local user for creating the virtual file system? For me these are completely different things. And why does it work with plain "ftp://"; vfs? As far as I understand it should also use VfsFileSystemFactory.createFileSystemView.
