Tab delimited file, to populate JTable

Question

Hey all
As Java is fairly new for me I have come into several problems.
First of all i have a program making a tab delimited file, for example like this:
Mig     12345    You
Gig      12345    DouNow i want to read the file and populate each line in the JTable.
But my problem is the transfer from file to object.. This is my code so far:
String[] kolonneNavne = {"Kursusnavn",
                                "Kursusnummer",
                                "Point",
                                "Skemaplacering",
                                "Liniefag",
                    "Kursus taget"};
          Object[][] kdata ={{null,null,null,null,null,null}};
          try {
               BufferedReader buff = new BufferedReader(new FileReader("kurser.ini"));
               String linie = buff.readLine();
               StringTokenizer t = new StringTokenizer(linie, "\t", false);
               String kursus[] = {null,null,null,null,null};
               int antalKurser = 0;
               while (linie != null){
                    kursus[0] = t.nextToken();
                    kursus[1] = t.nextToken();
                    kursus[2] = t.nextToken();
                    kursus[3] = t.nextToken();
                    kursus[4] = t.nextToken();
                    kdata[0][antalKurser] = kursus[0];
                    kdata[1][antalKurser] = kursus[1];
                    kdata[2][antalKurser] = kursus[2];
                    kdata[3][antalKurser] = kursus[3];
                    kdata[4][antalKurser] = kursus[4];
                    kdata[5][antalKurser] = new Boolean(false);
                    linie = buff.readLine();
                    antalKurser++;
          catch (ArrayIndexOutOfBoundsException e){                         
          catch (IOException e){
               e.printStackTrace();
          }This should read every line in the file, and add the contents to kdata but it doesn't.
I've tried several things, reading the "How to Use tables" by java, and also looking at the Class "Scanner", but havn't got that working either.
I think that the error is in the assigning kursus[j] and kdata[][], but how do i do it? How kan i add contents to an array already having information:
Object[][] kdata;?
Is there a smarter way?
Afterwards i do the essential:
final JTable table = new JTable(kdata, kolonneNavne);

Thanks for the debugging thing, i actually didn't know what it did..
Well if i change the assigning from the file with split, it should look like this:
try {
               // For at l�se en linie af gangen
               BufferedReader buff = new BufferedReader(new FileReader("kurser.ini"));
               String linie = buff.readLine();
               //Scanner sc = new Scanner(linie);
               StringTokenizer t = new StringTokenizer(linie, "\t", false);
               String kursus[] = {null,null,null,null,null};
               int antalKurser = 0;
               while (linie != null){
                    kdata[antalKurser] = linie.split("\t",5); // Or should this be kdata[0][antalKurser] ???
                    kdata[5][antalKurser] = new Boolean(false);
                    linie = buff.readLine();
                    antalKurser++;
          catch (IOException e){
               e.printStackTrace();
          }But i still get errors when running the code...
Do i assign the data correct? It seems to me that that is the problem... I have tried searching for "object assign data java" but, all that comes up is "Object oriented programming with java"... Which i s understandeble beacause of java being Object oriented...
Hmm.. Hope you could help me with assigning the data!
It comes with this error:
