Trying to code a ethereal-like application

Question

Hi all.
I am trying to code a mini-etheral like packet logging/attacks detection utility for security purposes. It will be very easy to do it in C but i wish to do it in Java. I want to print all the packet dump in hexadecimal on a notepad or text editor or something. I also want to detect which IP address is trying to attack you and print it to text etc (this part won't be too hard)
The problem is, i cannot find any tutorial on google teaching something similiar to this. Does anyone know any links related to this? Please help out if you do. I already have Java as well as some network programming knowledge so basically, i just need a good example similiar to what i am trying to create.
Much appreciated !

Hello,
In order to make it painted all the time you have to override the method
paint(Graphics g) in the JFrame class. In your program you have to override it either in the TLayer class or in the GameScreen class.
This is the new GameScreen class after this modification; this makes the rectangle painted after resizing.
import java.awt.Graphics;
public class GameScreen extends TLayer {
     private PoolApp thePoolApp;
     public GameScreen(PoolApp aPoolApp) {
          thePoolApp = aPoolApp; // set a reference from here to the controlling
                                        // PoolApp initGameScreen(); //initialise and
                                        // show GameScreen .....screen
          initGameScreen();
     public void initGameScreen() {
          this.setSize(800, 600);
          this.show();
          // now make a request to the poolapp controlling class to ask for a
          // painted green table and get the paint class to paint it to screen
          thePoolApp.getPaintedTable(this);
     public void paint(Graphics arg0) {
          super.paint(arg0);
          thePoolApp.getPaintedTable(this);
}Hope this helps you.
Feel free to ask, if you have any question .
