Positioning to bottom of a JList in a JScrollPane

[Robert Upshall]

I have a JList that is in a JScrollPane. It is possible for the list to be larger than the viewport. What I want to do is always position the scrollbar to the bottom of the list, the default is the top of the list. How do I set the scrollbar positon in a ScrollPane.
I have atempted
myScrollpane.getVerticalScrollBar().setValue(listSize);
but this doesn't appear to be working, is this the proper way? If not what would it be?

You do this through the list itself...

int size = list.getModel().getSize();
list.ensureIndexIsVisible( size - 1 );
