Gradient Painting

Hi all, I would like to paint a gradient
for a background color on  a pane.  I am using ULC 6.1, the example
that I have seen on the mailing list refer to a UiJPanel, but I am unable
to resolve this component.  Any help would be appreciated.  I
was looking at the following example.
