Compiler AVEC ECLIPSE

Bonjours Mrs,

Je n'arrive pas à completer ce code en java que j'ai commencé
je vous le donne
sjava.io.*;
import java.net.*;

class smtpClient {

private String server, message, dest, origin;
private int port;
private Socket socket;

public smtpClient (String serv, int por, String org)
{
server = serv;
port = por;
origin = org;
}

public void createMsg(String dst, String msg)
{
message = msg;
dest = dst;

}

public void sendMsg()
{
PrintWriter to;
BufferedReader from;
String str;

try {
socket = new Socket(InetAddress.getByName(server),port);

to = new PrintWriter(
new BufferedWriter (
new OutputStreamWriter (
socket.getOutputStream())),true);
from = new BufferedReader(
new InputStreamReader (
socket.getInputStream()));

str = from.readLine();
to.println("helo plus.bas");
str = from.readLine(); System.err.println(str);
to.println("mail from: <"+origin+">");
str = from.readLine(); System.err.println(str);
to.println("rcpt to: <"+dest+">");
str = from.readLine(); System.err.println(str);
to.println("data");
str = from.readLine(); System.err.println(str);
to.println(message + "\r\n.\r\n");
str = from.readLine(); System.err.println(str);

socket.close();

} catch ( Exception e ) {}

}

public static void main ( String args[] )
{
smtpClient c = new smtpClient("SMTP SERVER",25,"geffrene.fr.st");

c.createMsg("hegforestcontact@hotmail.com","Coucou");

c.sendMsg();

Ensuite j'ai aussi un autre problème avec mon compilateur ECLIPSE que je n'arrive pas à utiliser, pouvez vous m'aidez.

Merci.
