apache commons vfs delete directory with dependancies

[turanan]

I'm new to vfs and I want to know how I can remove a directory, which is not empty.

The following code seems to remove single files and empty directories quite easily:

    public void testRemoveRemoteFile() throws FileSystemException {
        FileSystemOptions fsOptions = new FileSystemOptions();
        SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(
                fsOptions, "no");
        DefaultFileSystemManager fsManager = (DefaultFileSystemManager) VFS.getManager();
        if (fsManager.resolveFile("sftp://user:pass@host/remotepath/", fsOptions).exists()) {
            fsManager.resolveFile("sftp://user:pass@host/remotepath/", fsOptions).delete();
            System.out.println("File removed successfully");
        }
    }

But I want my code to be able to remove directories, which have files or sub-directories in them. The spec says, that we should use fileObject.delete(FileSelector); instead of fileObject.delete();
but so far I haven't been able to use this method, as I don't know what this FileSelector type parameter should contain. If anyone has encountered this problem, please post an example, which removes non-empty files.

Thanks,
Andrew
