Thomas, 

your snippet looks good except that it must read "new JTree();"
But I guess that's just a typo in your post - it wouldn't compile
that way.
ScrollOnExpand is true by default, so you don't need to set it. 
It doesn't hurt, however. 
I can't comment on the Designer issue since I don't use it, 
but I assume your problems originate outside your snippet. 
Do you see the scollpane at all? 
Did you by chance add the table rather than the scrollpane 
to your parent panel/frame?
