Problema paquetes[No resuelve]

Buenas, el caso es que necesitaba de una API FTP, y encontre JvFTP, baje los .jars y hasta ahi bien, importa tambien lo que falta con:

Código:

import cz.dhl.io.*;
import cz.dhl.ftp.*;
import java.io.IOException;

Pero al compilarlo me da error, es como si no lo encontrara..

Código:

pepe@pepe:~/src$ javac FtpListTest.java

Y he añadido los .jar y demas, asi que no se que puede ser, si alguien lo sabe, se lo agradeceria.
