Using java.net.URL ftp facilities

This will open a connection to a directory and try to get the files list. Not tested yet, though.

final URL url = new URL("ftp://username:password@localhost/TEST;type=D");
final URLConnection connection = url.openConnection();
InputStream is = null;
try {
is = connection.getInputStream();
} catch(FileNotFoundException e) {
e.printStackTrace();
} finally {
if(is != null)
is.close();
}
