Horizontal List Box and JScrollPane

I have an array of Integers, which I want to display on my Panel HORRIZONTALLY(if there is such a word!). I want a Scrollbar under this list to allow the user to move across a list, and select an item. I want to add action listeners on the list which will reflect selection of an item.
 What should I use? The array  will have fixed 200 elements. I tried using JScrollPane with a listbox, but didn't know if that was the right way to go.

I have to figure this out asap.

Use a JTable with a single row.

Use a ListSelectionListener to listen for user selections.

this is the code i use: -

public JTable getlayerTabel(){
      layerTableModel = new DefaultTableModel(1,200);
      for(int i=0;i<200;i++){
            layerTableModel.setValueAt(new Integer(i),0,i);
      }
      JTable layerTable = new JTable(layerTableModel);
      layerTable.setBounds(5,25,45,35);
      JScrollPane layerScrollPane = new JScrollPane(layerTable);
      layerScrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
      return layerTable;
      }

But, in my display, i am not getting any slider on the ScrollBar. Also, is the default color of the scrollpanel white?
thanks

why do u do this?

> return layerTable;

Why aren't you returning your scroll pane?
You should be adding the scroll pane to your component hierarchy, not the table.

>  Also, is the default color of the scrollpanel white?

not sure of the top of my head. U can change it if need be.
