I have an application that has 3 JScrollPanes (viewing 3 JTables) and
a title for each table displayed in a tabbed pane (it is basically a
summary tab).  The JTabbedPane is in a JFrame.

My problem is that I build a JPanel that has my 3 tables and 3 titles
(JLabels) in it and then I add a tab with the JTabbedPane.add("my
tab", myJPanel) method.

When I resize the JFrame, the JPanel in the JTabbedPane does not
resize at all.  The only way I can get components to resize correctly
in a JTabbedPane is if I add the component with tabbedPane.add("my
tab", myJComponent);

What am I missing that will let my JPanel (and the stuff in my JPanel)
resize correctly when the JFrame is messed with?

Other things of note:
I am using GridBagLayout in the JPanel.  I believe that I am using it
correctly with weights set and fills set.

Any hints would be appreciated.
