Answer 1

The easiest way is to
1. Call tree.setDragEnabled(true)
2. set tree.transferHandler

There's a tutorial at: http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.html

You create a subclass of TransferHandler where you implement

canImport(JComponent comp, DataFlavor[] transferFlavors)

and

importData(JComponent comp, Transferable t)
