Multiple Components in a JScrollPane

Question

Hi all,
I'm trying to create a JScrollPane with multiple components in it, inside a TabPane. However I keep running into problems getting the display working.
The contents of the ScrollPane will be determined at runtime and will consist of "n" tables and JLabels, in no particular order. The only constraint is that I want to have the components displayed in rows (one column per row). The number of rows and columns in each of the JTables (and therefore their size) will also be determined at runtime.
I've run into problems where the JScrollPane only shows the last JTable added. I've tried adding a JPanel to the JScrollPane and then adding the tables to that, but the display doesn't work - maybe something I've missed on the sizing?
Any clues on where I should focus will be most appreciated.
Thanks

Hi,
Thanks for the suggestion - I've tried using the following test code, but I cannot get it to display anything:
public class AFrame extends JFrame {
  private JScrollPane jScrollPane1 = new JScrollPane();
  public AFrame() {
    try {
      this.getContentPane().setLayout(new BorderLayout());
      this.setTitle("Test Frame");
      this.setSize(500, 500);
      setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      this.getContentPane().add(jScrollPane1, null);
      jScrollPane1.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
      jScrollPane1.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
      //create a table   
      JTable table1 = new JTable();
      table1.setModel(new TestTableModel());
      TableColumnModel colmod = table1.getColumnModel();
      for (int i=0; i < table1.getColumnCount(); i++) {
        TableColumn col = colmod.getColumn(i);
        col.setPreferredWidth(50);
      //create an edit field
      JEditorPane jep1 = new JEditorPane();
      jep1.setPreferredSize(new Dimension(100, 20));
      //create the panel & add two components
      JPanel p = new JPanel();
      p.setPreferredSize(this.getSize());
      double size[][] =
        {{10, TableLayout.PREFERRED, 10},  // Columns
         {10, TableLayout.PREFERRED, 10}}; // Rows
      TableLayout tl = new TableLayout(size);
      p.setLayout(tl);
      p.add(table1, "1, 1");
      p.add(jep1, "1, 2");
      validate();
      setVisible(true);
    catch(Exception e) {
      e.printStackTrace();
  public static void main(String[] args) { new AFrame(); }
//The TestTableModel dummy class for testing
public class TestTableModel extends AbstractTableModel  {
  public TestTableModel() {
  public int getRowCount() {
    return 2;
  public int getColumnCount() {
    return 10;
  public Object getValueAt(int row, int col) {
    return "Test value";
}
