Здравствуйте я пытаюсь написать программу которая открывает файл тхт и каждую строчку засовывает в строчки jlist-а.

вот моя версия

Java

     JFileChooser fileopen = new JFileChooser();
     int ret = fileopen.showDialog(null, "Открыть файл");                
     if (ret == JFileChooser.APPROVE_OPTION) {
     File file = fileopen.getSelectedFile();
    try {
          while(scn.hasNext()){
             for(int row=0;row<m.length;row++){
               m[row]=scn.next();
               DLM.addElement(m[row]);
             }
        }
          scn = new Scanner( new FileReader(file.getAbsolutePath()));
        } catch (IOException ex) {
          System.out.println("problem accessing file"+file.getAbsolutePath());
        }
}
     jList1.setModel(DLM);

но нечего не получается((((. В чем ошибка?
