Now i install the jdk 1.6.0_20 and add into the jdeveloper 10.1.3.
and i change my code for get mac id is -
package demo;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class App{
   public static void main(String[] args){
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());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e){
e.printStackTrace();
in form i create one jave bean area and add the implement class is
demo.get_info.
and on B1 (button) when-button-pressed
:T1 :=GET_CUSTOM_PROPERTY('BEAN_MAC',1,'get_info');
No error comes and no out put comes. So please guide me how to use the getHardwareAddress to get mac id.
