    jTsearch.getDocument().addDocumentListener(new DocumentListener() {
    public void changedUpdate(DocumentEvent e) {
        //whatever you want
    }
    public void removeUpdate(DocumentEvent e) {
       //whatever you want
    }
    public void insertUpdate(DocumentEvent e) {
      //whatever you want
    }
  }
});
