Problem in tabbed panes

Question

hai friends,
i am trying to create a tabbed pane which contains 3 panes.(top)
and i try to add a tabbed pane at bottom of first pane which is a panel.
i have set the size of panel as panel.setPreferredSize(new Dimension(750, 475));
Now i am finding i cannot view the tabbed panes added to the panel.
the relevant code is given below.
some one have any idea..
panel.add(new JScrollPane(textArea));
panel.add(new JScrollPane(table));
panel.setPreferredSize(new Dimension(750, 475));
panel.setBackground(Color.PINK);
JTabbedPane tabbedPane2 = new JTabbedPane     (JTabbedPane.BOTTOM);
tabbedPane2.add("Result",new JTable(10,10));
tabbedPane2.add("Message",new JTextArea());
panel.add(tabbedPane2);
JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.TOP);
tabbedPane.addTab("name1", new JScrollPane(panel));
tabbedPane.addTab("name2",
     new JScrollPane(new JTextArea(5, 5)));
tabbedPane.addTab("ANALYSIS", new JButton("<   HAI ALL   >"));
container.add(tabbedPane);
tabbedPane.setBackground(Color.ORANGE);
