JFrame uses a BorderLayout by default. It's default position (if you don't specify one) is CENTER.

BorderLayout will only allow one component to occupy any of it's 5 available positions.

So when you do...

jframe.add(scrollFrame);
jframe.add(container);

It adds the scrollFrame to the center position and effectively removes it when you add container (it doesn't actually remove it, but the result is just about the same).

Try supplying a position constraint. For example...

jframe.add(scrollFrame);
jframe.add(container, BorderLayout.SOUTH);
