Invoking telnet/ftp from a Java Program

Question

How do I invoke telnet/ftp from a Java Program.
I tried Runtime.getRuntime().exec("telnet x.x.x.x")
where x.x.x.x is the IP address from my XP machine but doesn't work.
Thanks

import sun.net.ftp.*;
import sun.net.TelnetInputStream;
import java.io.*;
class ex_ftp01 {
public static void main(String[] args) {
try {
int i;
String server = "xx.xx.xx.xx";
String user = "yy";
String passwd = "zz";
FtpClient client = new FtpClient();
client.openServer(server);
client.login(user,passwd);
System.out.println("Logined");
// client.binary();
client.cd("/xx");
TelnetInputStream in = client.get("abc.txt");
BufferedReader d = new BufferedReader(new InputStreamReader(in))
while (( i = d.read()) != -1 ) {
System.out.write(i);
System.out.println("End of reading");
catch (Exception e) {
System.out.println(e);
}
