small FTP app, commons-net-ftp, problems with run

[metoda]

Hello. I am newbe Java programmer, as I have wrote my first java application two days ago, so be tolerant. I am using NetBeans IDE 6.7.1. I am writting small application, which is to connect with FTP server, and as a first step, it displays names of the files at the server. For this purpose I am using not standard library from Apache : commons-net-ftp-2.0.jar. This library has been installed properly. It is visible in NetBeans in Libraries section of teh project. Everything works fine.
When I bulid Main Project, the file myfile.jar is build in folder "dist". When I try to run application by Run Main Project, everything works OK (I can connect to teh server and show the names of files.)
This is my code:

package ftpupload;
import java.io.File;
import org.apache.commons.net.ftp.FTPClient;

public class Main {
    public static void main(String[] args) {
   
    int i=0;

    try{
        FTPClient fcl= new FTPClient();
        fcl.connect("ftp.nazwaserwera.pl");
        fcl.login("user", "password");
        String[] files = fcl.listNames();
        System.out.println(fcl.getStatus());
        while(i<files.length){
                System.out.println(files[i]);
                i++;
        }
        fcl.logout();
    }
    catch (Exception E) {
      System.err.println(E.getMessage());
    }
    }
}

The problem apperas when I want to run this app in console outside NetBeans IDE.
When I put(in the "dist" folder of the project): java -jar myfile.jar
I get this message:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/ne
t/ftp/FTPClient
Caused by: java.lang.ClassNotFoundException: org.apache.commons.net.ftp.FTPClien

Could not find the main class: ftpupload.Main. Program will exit.

My main question:
1.Can You tell me where the problem is ??

I also wonder about some other things:
2. Do I have to add manually not standard, as it works fine in NetBeans but not on the console ??
3. How can I add this not standart library, so it will be possible to run this app on the machine, where this library is not installed ( only JVM present ).

Thanks in advance, and sory for my english.
Best regards from Poland.

I'm just guessing, but maybe the library is only installed for NetBeans and it is not in the PATH of your operating system. So search in Google how to add non-standard librarys to Java.
