how to compile classes not in API

[Kene Ifedi]

i am writing a code on telnet networking , i downloaded a library to help me with some classes but i can't compile it because it displays errors like package does not exit. please i need to know how to compile it. here is a snippet of the code

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileOutputStream;
import java.util.StringTokenizer;

import org.apache.commons.net.telnet.TelnetClient;
import org.apache.commons.net.telnet.TelnetNotificationHandler;
import org.apache.commons.net.telnet.SimpleOptionHandler;
import org.apache.commons.net.telnet.EchoOptionHandler;
import org.apache.commons.net.telnet.TerminalTypeOptionHandler;
import org.apache.commons.net.telnet.SuppressGAOptionHandler;
import org.apache.commons.net.telnet.InvalidTelnetOptionException;


/***
 * This is a simple example of use of TelnetClient.
 * An external option handler (SimpleTelnetOptionHandler) is used.
 * Initial configuration requested by TelnetClient will be:
 * WILL ECHO, WILL SUPPRESS-GA, DO SUPPRESS-GA.
 * VT100 terminal type will be subnegotiated.
 * <p>
 * Also, use of the sendAYT(), getLocalOptionState(), getRemoteOptionState()
 * is demonstrated.
 * When connected, type AYT to send an AYT command to the server and see
 * the result.
 * Type OPT to see a report of the state of the first 25 options.
 * <p>

public class TelnetClientExample implements Runnable, TelnetNotificationHandler
{
    static TelnetClient tc = null;

    /***
     * Main for the TelnetClientExample.
     ***/
    public static void main(String[] args) throws Exception
    {
        FileOutputStream fout = null;

        if(args.length < 1)
        {
            System.err.println("Usage: TelnetClientExample1 <remote-ip> [<remote-port>]");
            System.exit(1);
        }

You need to include the jar file in your classpath.

It also helps if you tell us what the exact errors are, rather than just what they are like.

[Tushar Kapila]

did you include all the jars from http://commons.apache.org/net/download_net.cgi in your classpath?


From http://commons.apache.org/net/download_net.cgi download a version like http://apache.techartifact.com/mirror//commons/net/binaries/commons-net-3.1-bin.zip
, extract zip/ tar, include commons-net-3.1.jar in your classpath besides other jars if you use them later (like log4j)


you could use ant to make a classpath jar ... look at http://ant.apache.org/manual/Tasks/manifestclasspath.html
