import org.apache.commons.net.ftp.FTPClient gives errors need jar files

Hi Experts,
I am trying to write a code for Streamserve application. Once I put this line import org.apache.commons.net.ftp.FTPClient in my code , I am getting errors. Thus I am sure I am missing some jar files required. Other lines which are giving errors are

import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;
import streamserve.connector.StrsConfigVals;
import streamserve.connector.StrsInDataQueueable;
import streamserve.connector.StrsServiceable;


Thus please kindly help me to get the required jar files. i am compiling the code in j2se 1.4.2_15 version.

regards
Anupam

What errors? You failed to post them...do you have the apache commons net library on the classpath?

What doWhile says.
Also, do you have those jar files?
If not then you need to get hold of them.
If you do then you need to tells us how you are compiling or running the code.
