Client ohne Server?

[joni]

Hallo zusammen,

ich befasse mich gerade mit tcp sockets und will einen Client machen der einfach sendet (an einen bestehenden Sever (nicht java))

Also der Client soll einfach ein Wort an den Server senden aber ich habe immer nur Beispiele gesehen die Client und Server sind und irgendwie zusammen gekoppelt.

Zu meinem Projekt: Also ich habe eine virtuelle Waage wo man das Gewicht einstellen kann und dass soll es an ein Programm senden der schon einen tcp collector bzw. listener hat. und dieser Client soll ganz einfach das gewicht senden. Kann mir da jemand helfen?

Grüsse

Socket erstellen, binden, connect aufrufen, getOutputStream() und dann da reinschreiben, evtl nen Printwriter drüberlegen wenn du text haben willst. Evtl, das encoding des printstreams/Outstreams entsprechend einstellen, so das dein Zeilclient das versteht.

 

[Geeeee]

Dann nimm doch nur die Clientseite aus den Beispielen. Es ist dem Client schlicht egal, wohin er sich verbinden soll.
Also einfach ein Socket mit den Serverinfos aufreißen und die Infos senden.

Danke vielmals,

jetzt bin ich aber auf eis :S

ich weiss es ist nicht sinnvoll wenn man sich code aus dem Internet zusammen sucht und es dann andere ausbaden lässt aber ich brauch hilfe.

ich habe mir einen Client geladen und der funktioniert gut, aber der hat eine GUI und ich weiss nicht wie ich die Weg bekomme so dass ich es in meine eigene GUI implementieren kann.

hier der Code des Clients:

package gui;

import java.awt.Color;
import java.awt.BorderLayout;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import java.net.*;

public class Client extends JFrame 
		 implements ActionListener {

   JLabel text, clicked;
   JButton jButton2;
   JPanel panel;
   JTextField textField;
   Socket socket = null;
   PrintWriter out = null;
   BufferedReader in = null;

   Client(){ //Begin Constructor
     text = new JLabel("Text to send over socket:");
     textField = new JTextField(20);
     jButton2 = new JButton("Click Me");
     jButton2.addActionListener(this);

     panel = new JPanel();
     panel.setLayout(new BorderLayout());
     panel.setBackground(Color.white);
     getContentPane().add(panel);
     panel.add("North", text);
     panel.add("Center", textField);
     panel.add("South", jButton2);
   } //End Constructor

  
   public void actionPerformed(ActionEvent event){
     Object source = event.getSource();

     if(source == jButton2){
//Send data over socket
          String text = textField.getText();
          out.println(text);
	  textField.setText(new String(""));
     
     }
  }
  
  public void listenSocket(){
//Create socket connection
     try{
       socket = new Socket("192.168.0.38", 4000);
       out = new PrintWriter(socket.getOutputStream(), true);
       in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
     } catch (UnknownHostException e) {
       System.out.println("Unknown host:" + socket);
       System.exit(1);
     } catch  (IOException e) {
       System.out.println("No I/O");
       System.exit(1);
     }
  }

   public static void main(String[] args){
        Client frame = new Client();
	frame.setTitle("Client Program");
        WindowListener l = new WindowAdapter() {
                public void windowClosing(WindowEvent e) {
                        System.exit(0);
                }
        };

        frame.addWindowListener(l);
        frame.pack();
        frame.setVisible(true);
	frame.listenSocket();
  }
}

Aber irgendwie macht er noch nichts, der Server erhält den Wert nicht, kann mir jamand helfen wie ich das lösen könnte?

hm nochmal lesen was ich geschreiben habe, evtl kenntnisse der socketapi auffrischen, und dann selber programmieren.

 

[Blakh]

Also ich sehe nirgends wo du was sendest ...

//Send data over socket
             String text = jTextPane1.getText();
           jTextPane1.setText(new String(""));

Wo sendest du denn hier was? Du haust den Text in eine lokale Variable rein und das ist dann weg nachdem die Methode zu Ende ist.

Das ist nur damit die TextPane sich wieder leert nach dem Senden, er holt sich ja den text via getText()

aber das Problem hat sich mitlerweile gelöst, ich idiot habe einfach vergessen den listenSocket() zu initialisieren das wars auch schon, dann funzt alles tipp top :toll:
