Question

    wireless toolkit code

//j2me code for client mobile

    public class TCPConnectSend extends MIDlet implements CommandListener {
    Display display;

    public TCPConnectSend0 () {
    frm = new Form ("TCPConnectSend0");
    sendCmd = new Command("Send",Command.SCREEN, 1);
    frm.addCommand(sendCmd);
    frm.setCommandListener(this);
    text = new TextField("text:","",40,TextField.ANY);
    frm.append(text);
    }
    public void startApp() {
    if(display==null) {
    display = Display.getDisplay (this);
    }
    display.setCurrent(frm);
    try {
    conn=(SocketConnection)Connector.open("socket://|ip-address|:80");//socket connection to the server

    outs=conn.openOutputStream();
    } catch(IOException e) { }
    }
    public void pauseApp() { }
    public void destroyApp(boolean unconditional) { }
    public void commandAction(Command c, Displayable s) {
    if(c==sendCmd) {
    try {
    outs.write((text.getString()+"\n").getBytes());
    } catch(IOException e) {}
    } else { }
    }
    }

    server code

//this receives the socket request from client

    class TCPServer
    {
       public static void main(String argv[]) throws Exception
          {
             try {
                ServerSocket server = new ServerSocket(80);
        System.out.println("ip address : "+InetAddress.getLocalHost());         
        System.out.println("waiting for connection");               
        Socket s1 = server.accept();
        System.out.println("connection established");
        BufferedReader br = new BufferedReader(new
InputStreamReader(s1.getInputStream()));    
            while (true) {
                String str1 = br.readLine();
            System.out.println("client says :" +str1);              
                if (str1.equals("quit"))
                        break;
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
          }
    }

//after running this code i m getting a java security exception in my nokia phone any other port no is no responding in the nokia phone

Answer 1

the problem happened because Nokia was blocking the 80 port no for some of its system application so changing of port no along with public ip address did the trick
