Order of elements in Hashtable

Question

My code:
Hashtable tabCtrl = new Hashtable();
tabCtrl.put("jTextField01", jTextField01);
tabCtrl.put("jTextField02", jTextField02);
tabCtrl.put("jTextField03", jTextField03);
tabCtrl.put("jTextField04", jTextField04);
tabCtrl.put("jTextField05", jTextField05);
tabCtrl.put("06", jTextField05);
tabCtrl.put("07", jTextField05);
tabCtrl.put("08", jTextField05);
tabCtrl.put("09", jTextField05);
tabCtrl.put("10", jTextField05);
tabCtrl.put("11", jTextField05);
Enumeration ex = tabCtrl.keys();
while (ex.hasMoreElements()) {
String alias = (String)ex.nextElement();
System.out.println(alias);
Output:
jTextField05
jTextField04
jTextField03
jTextField02
jTextField01
11
09
10
08
07
06
Why not so:
11
09
10
08
07
06
jTextField05
jTextField04
jTextField03
jTextField02
jTextField01

Hi,
I tried a TreeMap to keep ordering of my elements but it doesn't work. Why ?
import java.util.*;
class Mapping {
  public static void main(String[] args) {
    TreeMap map = new TreeMap();
    map.put("Type of realm used", "0");
    map.put("Name of the file used", "1");
    map.put("The database's driver", "2");
    map.put("The database's URL", "3");
    map.put("The database's user", "4");          
    System.out.println("\nmap0>"+ map +"\n");
}Here's the output :
map0>{Name of the file used=1, The database's URL=3, The database's driver=2, The database's user=4, Type of realm used=0}
Anyone knows how to do ?
I'm using JDK1.3.x, so I can't use the class LinkedHashMap from JDK1.4.
Thank you for your help.
