 public DataModel getTablo(){
 liste =new ArrayList();
 tablo=new ListDataModel();

 liste.add(k);
 k=new Kol("4","d","4d");
 liste.add(k);
 k=new Kol("9","g","9g");
 liste.add(k);
 k=new Kol("11","r","11r");
 liste.add(k);
 k=new Kol("3","f","3f");
 liste.add(k);
 k=new Kol("90","t","90t");
 liste.add(k);
 k=new Kol("5","i","5i");
 liste.add(k);


 tablo.setWrappedData(liste);
 return tablo;

 }

here is my De managed bean code for getting row value that clicked by user:

 public String bak1(){
 Kol k=(Kol)this.tablo.getRowData();
 System.out.println(k.getAd());
 System.out.println(k.getSoyad());
 System.out.println(k.getKey());
 return "h";
 }
