Socket ultra simple

Bonjour,

je cherche à faire un petit script en java.
il y a un serveur et un client sur 2 machines différente.

je voudrais simplement vérifier la communication entre les deux machines.

Est il possible de faire un script avec des socket tres tres simple.
Le client envoie un charactere au serveur et le serveur lui en renvoie un autre.
enfin pas de buffer, vraiment tres simple.

dans le script client je voudrais choisir le port et l'ip pour le serveur(en tcp pour l'instant je ferrais l'udp après, si j'arrive avec tcp;-).

je suis assez null en java et tous les exemples sur internet sont un peut trop compliqué. il y a bien un jeu d'instruction minimum pour faire une socket?

merci

essayer ce code:

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

declaration: BufferedReader in; BufferedWriter out; String line; private Socket soc; ServerSocket ss; corp du programme: try{ ss = new ServerSocket(5555); soc = ss.accept();   out.println("-Bonjour > "+InetAddress.getLocalHost().getHostAddress()+"\nVous êtes connecté\n"); out.flush(); out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(soc.getOutputStream())),true); out.flush(); in = new BufferedReader(new InputStreamReader(soc.getInputStream())); while ((line = in.readLine()) != null) { out.println("-Message reçu\n"); out.flush();   if(line.equals("exit")) { try { out.println("Au revoir "+nbrclient+" "+InetAddress.getLocalHost().getHostAddress()+"\nvous êtes déconnecté"); out.flush();   in.close(); out.close(); soc.close();   } catch(IOException e) {System.out.println(e.getMessage());} }

tu vérifie si ce code marche ou non, à partir d'une console msdos: démarrer>exécuter et tu tape la commande telnet localhost 5555
j'espère que cela vous aide
tu peut voir ce lein aussi, c'est très utile:

donc au niveau des commentaires client et serveur je voudrais intégrer le code des sockets.

le lien http://pages.univ-nc.nc/~touraivane/...00000000000000

est tres bien mais je ne comprend pas, il y a plein de bout de code et je ne sais pas quoi placer et ou.

tu peux t'aider du ActionListener:

Code:

---

tonbouton.addActionListener(new ouvrirSocket());

---

puis:

Code:

---

1 2 3 4 5 6 7 8

class ouvrirSocket implements ActionListener {   public void actionPerformed(ActionEvent e) {   //insérer code   } }

---

et dedans tu mets ton code et n'oublie pas bien sur de l'entourer avec le fameux try-catch
j'espère que cela t'aide
