You should use ListCellRenderer to add the separators at specific positions…

 jList1 = new javax.swing.JList();
//String[] strings = { "Item 1", "Item 2", "Item 3", "Item 4", "Item 5" };
jList1.setModel(new javax.swing.AbstractListModel() {
    String[] strings = { "Item 1", "Item 2", "Item 3", "Item 4", "Item 5" };
    Vector v = makeVectorData(strings);
    public int getSize() { return v.size(); }
    public Object getElementAt(int i) { return v.get(i); }
});
jList1.setCellRenderer(new JlistRenderer());
jList1.addFocusListener(new JListFocusListener(jList1));

public class JlistRenderer extends JLabel implements ListCellRenderer {
JSeparator separator;
final String SEPARATOR = "SEPARATOR";
public JlistRenderer() {
setOpaque(true);
setBorder(new EmptyBorder(1, 1, 1, 1));
separator = new JSeparator(JSeparator.HORIZONTAL);
}
public Component getListCellRendererComponent(JList list, Object value,
int index, boolean isSelected, boolean cellHasFocus) {
String str = (value == null) ? "" : value.toString();
if (SEPARATOR.equals(str)) {
return separator;
}
if (isSelected) {
setBackground(list.getSelectionBackground());
setForeground(list.getSelectionForeground());
} else {
setBackground(list.getBackground());
setForeground(list.getForeground());
}
setFont(list.getFont());
setText(str);
return this;
}
}

public class JListFocusListener implements FocusListener {
JList list;
Object currentItem;
final String SEPARATOR = "SEPARATOR";
JListFocusListener(JList list) {
this.list= list;
list.setSelectedIndex(0);
currentItem = list.getSelectedValue();
}
public void focusGained(FocusEvent e) {
String tempItem = (String) list.getSelectedValue();
if (SEPARATOR.equals(tempItem)) {
list.setSelectedValue(currentItem,true);
} else {
currentItem = tempItem;
}
}
}

Hope the above code helps...
