Register a MouseListener with your JTree, and when you receive a MouseEvent
check whether getClickCount() == 2

The JTree is just one component, so you don't register listeners on the
nodes themselves.
Seems like the JavaDoc for JTree already has it covered:
If you are interested in detecting either double-click events or when a user
clicks on a node, regardless of whether or not it was selected, we recommend
you do the following:

final JTree tree = ...;

MouseListener ml = new MouseAdapter() {
public void mousePressed(MouseEvent e) {
int selRow = tree.getRowForLocation(e.getX(), e.getY());
TreePath selPath = tree.getPathForLocation(e.getX(), e.getY());
if(selRow != -1) {
if(e.getClickCount() == 1) {
mySingleClick(selRow, selPath);
}
else if(e.getClickCount() == 2) {
myDoubleClick(selRow, selPath);
}
}
}
};
tree.addMouseListener(ml);
