package my.testsms.essaie;
 
import java.io.IOException;
import java.io.InputStream;

public class Essaie {
    private InetAddress remoteaddr;
    private boolean status;
    private Socket client;
    private BindTransceiver bindtrans;
    private OutputStream sout;
    private InputStream sin;
 
    private Connection conn;
    String ipaddress = "x.x.x.x";
    int port = 5016;
    int localPort = 2500;
    String sysId = "xxx";
    String pwd = "xxx";
    String systemType = "0";
    int sourceTON = 0;
    int sourceNPI = 0;
    String addrRange = " ";
    boolean retry = false;
    BindResp bindResponse;
 
 
    public void connect() throws UnknownHostException, IOException {
        // Create the TCP link...
        InetAddress localAddress = InetAddress.getByName("ptb_harold");
        System.out.println(localAddress);
        client = new Socket(ipaddress, port, localAddress, localPort);
        System.out.println(client.getRemoteSocketAddress());
 
        remoteaddr = client.getInetAddress();
 
        System.out.println(remoteaddr);
        TcpLink link = new TcpLink(remoteaddr, port);
        link.open();
        status = link.isConnected();
        System.out.println(status);
 
 
    }
 
    public static void main(String[] args) throws UnknownHostException, IOException {
        Essaie test = new Essaie();
        test.connect();
    }
}

le programme s'execute mais quand je fais un tcpview je ne vois aucune trace d'une communication.
quel est mon erreur?
