Running a java program with eclipse

Question

Hi,
I'm trying to run this java program(below) in eclipse..when i go to the 'run' icon inorder to choose the option 'run as' then 'java application' , i have 'none applicable' as the only option available. is it possibly because the program uses threads?
could someone using eclipse please try to execute this program and let me know if you succeed and how exactly you do it.
package reseaux;
import java.io.*;
import java.net.*;
import java.util.*;
     public class LeServeur extends Thread{
     Socket socket;
     BufferedReader in;
     PrintWriter out;
     Vector FlowList=new Vector(10);
     public LeServeur(Socket socket)throws IOException{
          this.socket=socket;
          in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
          out= new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));
     public void run(){
          String s;
          synchronized(FlowList){
               FlowList.addElement(this);
          try{
               while(!(s = in.readLine()).equalsIgnoreCase("/quit")){
                    for(int i=0;i<FlowList.size();i++){
                         synchronized(FlowList){
                              LeServeur monServeur=(LeServeur)FlowList.elementAt(i);
                              monServeur.out.println(s + "\r");
                              monServeur.out.flush();
          catch(IOException e){
               e.printStackTrace();
     finally {
     try {
          in.close();
          out.close();
          socket.close();
     } catch(IOException ioe) {
     } finally {
          synchronized(FlowList) {
          FlowList.removeElement(this);
thanks

thanks...
Infact, i wanted to run the main program called 'Serveur' but it uses 'LeServeur'( the code i sent before') and apparently it gives me an error msg that it doesnot recognise the 'LeServeur'...that's why i was thinking that i should probably first compile the 'LeServeur' so that it can be recognised in the 'Serveur' program.
here is the 'Serveur' code that uses an instantiation of the LeServeur...
package reseaux;
import java.net.*;
import java.io.*;
public class Serveur {
          public int port;
          public ServerSocket skt;
          public Socket socket;
     public static void main(String[] args) {
          int port=8975;
          ServerSocket skt=null;
          Socket socket=null;
          try{
               if(args.length>0)
                    port=Integer.parseInt(args[0]);
          catch(NumberFormatException n){
               System.out.println("This port is used uniquely for listening");
               System.exit(0);
          try{
               skt= new ServerSocket(port);
          while (true){
               socket =skt.accept();
               LeServeur flow=new LeServeur();
               flow.start();
     catch(IOException e){
          e.printStackTrace();
     finally{
          try{
               skt.close();
          catch(IOException e){
               e.printStackTrace();
do you know have any idea why it doesnt recognise the 'LeServeur'?
ps:they're in the same package
thanks
