unable to add scrollp pane to a panel in an applet

I have an applet with a JTabbedPane .
One of the tabs has a JPanel on which I draw using the Graphics g
context.
Since the diagram turns out to be very large I tried adding a
JScrollPane to this JPanel using code

------------------------------------------------------------

JScrollPane myScroll = new JScrollPane( myPanel ) ;

------------------------------------------------------------

but the scroll bars do not show up.

I also tried

-----------------------------------------------------------

JScrollPane myScroll = new JScrollPane( mapArea ,

JScrollPane.VERTICAL_SCROLLBAR_ALWAYS ,

JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS) ;

--------------------------------------------------------------

but still no result

can anyone please help me.

Thanks in advance

a) Make sure that your panel has a preferredSize parameter which
reflects its true size. (Call setPreferredSize)

b) Ensure that you add "myScroll" to the JTabbedPane and not "myPanel".
If you do the latter, it will be automatically removed from its existing
parent - namely the JScrollPane's viewport.
