getting the icon back to the header

hi.
i want to put an icon in the header(like the fox icon in the FF browser etc.) instead of the Java icon.
i tried something out,but for now, i only managed to remove the icon at all... :-S
my code looks like that (not all of it, just the parts needed here...)

public class BootStrap
{      static String ImageIconFolder;
      static ImageIcon tPointerLogo;
      public BootStrap(String timageIconFolder,ImageIcon pointerLogo){
            ImageIconFolder=timageIconFolder;
            tPointerLogo=pointerLogo;
      }
public static void main(String args[])
{      String ImageName="\\PointerLogo.jpg";
      String ImageFolder="C:\\Temp";
      String ImageIconFolder=ImageFolder.concat(ImageName);
tPointerLogo = new ImageIcon(ImageIconFolder);

new LoopSMS("Loop SMS Ver. 1.01");
// LoopSMS.setIconImage(PointerLogo.getImage());
}
}

... //constructor
public LoopSMS(String frameTitle)
{
super(frameTitle);
//initialise components
init();
//construct GUI
construct();
//Display GUI
display();
}

private void construct()
{
ImageIcon PointerLogo = new ImageIcon();
PointerLogo=BootStrap.tPointerLogo;

// JFrame MainFrame = new JFrame("Loop SMS Ver. 1.01");
this.setIconImage(PointerLogo.getImage());
// MainFrame.setLocationRelativeTo( null );
this.getContentPane().add(this.MainFramePanel);
// MainFrame.add(MainFramePanel);
MainFramePanel.add(DLPanel);
....}

how do i fix that?

Different solution:

public static void main(String args[])
{
String ImageName="\\PointerLogo.jpg";
String ImageFolder="C:\\Temp";
String ImageIconFolder=ImageFolder.concat(ImageName);
tPointerLogo = new ImageIcon(ImageIconFolder);

LoopSMS ls = new LoopSMS("Loop SMS Ver. 1.01");
ls.setIconImage(tPointerLogo.getImage());
}

Btw, a lot of rubbish in your code, try to keep your code clean and simple.
I think you are missing the idea of static vs non-static. If you have a class Student and you want an instance of that class you do:

Student instanceStudent = new Student();

Now if you want to call a method on such object you do:

instanceStudent.methodname();

This will call the object and all the class-attributes are set for this specific student. While if you do:

Student.attribute;

then you can only do so, if the attribute is static (since Student is not an instance/object but a class name).
So small example:

class Student
{
final static String school = "university college";
public int id;
private int pid;

public Student(int id)
{
this.id = id;
this.pid = id*2;
}

public int getPid()
{
return pid;
}
}

This class has one constructor (namely Student(int id)) and a method getId() which returns the id of the student. There are three attributes, one static (value) and one non-static (id). Id is public, but pid is private.

So lets look at the follow example code:
Student s1 = new Student(10);
System.out.println(Student.school); //outputs "university college"
System.out.println(Student.id); //not possible, variable is non-static
System.out.println(s1.id); //outputs 10
System.out.println(s1.getPid()); //outputs 20
System.out.println(s1.pid); //not possible, variable is private

I'm not sure if I explained this well enough for you to understand, but there is a lot of redundancy in your code.

Good luck.
