You have to write your own renderer.
example:
public class MyListsRenderer extends JPanel implements ListCellRenderer {
     JTextArea t;
     private LinkedHashMap<Integer, String> departmentsList;
     private LinkedHashMap<Integer, Boolean> checkedList;
     public MyListsRenderer(int tabSize) {
          t = new JTextArea();
          t.setTabSize(tabSize);
     public Component getListCellRendererComponent(JList list, Object value,
               int index, boolean isSelected, boolean cellHasFocus) {
          Integer id = (Integer) value;
          // you need to create class that get an id (value) and return name
          //this is my example:
          String name = Contacts.getInstance().getContacts().get(
                    (Integer) value);
          t.setText(name);//this is the text in the list row
          add(t);
          return this;
}
