Answer 1

Do IP address check,mac address check etc inside war so even if war is deplyod it will not work if ip or mac address is incorrect. ie….Change the code in war like that

A sample java program to get IP address and MAC address is given below

 import java.net.InetAddress;
    import java.net.NetworkInterface;
    import java.net.SocketException;
    import java.net.UnknownHostException;

    public class MACandIP{

       public static void main(String[] args){

        InetAddress ipAddress;
            byte[] macAddress;
        try {

            ipAddress = InetAddress.getLocalHost();
            System.out.println("IP address =" + ipAddress.getHostAddress());
            NetworkInterface networkInt = NetworkInterface.getByInetAddress(ipAddress);
            macAddress = networkInt.getHardwareAddress();
            StringBuilder strBld = new StringBuilder();
                    System.out.print("MAC address = ");
            for (int i = 0; i < macAddress.length; i++) {
                strBld.append(String.format("%02X%s", macAddress[i], (i < macAddress.length - 1) ? "-" : ""));
            }
            System.out.println(strBld.toString());

 //in above code assume you got MAC address as  81-7B-39-C5-A6-D4 

                if(strBld.toString().equalsIgnoreCase("81-7B-39-C5-A6-D4")){
                    // mac is correct 
                }

        } catch (UnknownHostException excep) {

            excep.printStackTrace();

        } catch (SocketException exce){
            exce.printStackTrace();
        }

       }

    }
