Java App Question

[CrimsonGhost]

Right I'm doing up a java app with Swing. I've two JScrollPane left and right of app. Each pane have a JTree in it. I want to be able to drag nodes from Left Tree to right Tree. So left one has to implement Draggable, and Right one Droppable. Problem is this. Do the JScrollPane, JTree, or DefaultMutableNodes implement the Draggable and droppable. I've been looking at examples from java.sun.com but I can't figure out the best way to implement this. Any ideas?

Cheers.
Dave.
