sending mac address from client pc to server pc in jsf

Question

first i get mac address from pc client like this

public void getterMacAddress(){
      InetAddress ip;
    try {

        ip = InetAddress.getLocalHost();
        System.out.println("Current IP address : " + ip.getHostAddress());

        NetworkInterface network = NetworkInterface.getByInetAddress(ip);

        byte[] mac = network.getHardwareAddress();

        System.out.print("Current MAC address : ");

        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < mac.length; i++) {
            sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));        
        }
        System.out.println(sb.toString());
                macAddress = sb.toString();

    } catch (UnknownHostException e) {

        e.printStackTrace();

    } catch (SocketException e){

        e.printStackTrace();

    }
    }

i get the mac address successfull, but how i can send that mac address to server?

What do you mean sending it to the server. When you deploy the application on the server, its already there. You just need to read it — Shervin Asgari, Apr 15 '13 at 09:38

You may pass a String to server(JSF) as URL parameter

myserver:port/myproject/innerpage/mac.jsf?mac=5C-AC-4C-75-44-4A

public class Bean {

@ManagedProperty(value="#{param.mac}")
private String mac;

@PostConstruct
public void init() {
    System.out.println(mac); // 5C-AC-4C-75-44-4A
}
// ...
}

Also look at this question: parameter in URL jsf2

I do not recommend using JSF for this purpose. Servlet or REST web sevice - is a better way.
