	private static final long serialVersionUID = 1L;
	JPanel pnlMain = new JPanel();
	Color c = new Color(255, 255, 225);
	JTree treeTemp = new JTree();

	public TestTree(){
		jbInit();
	}
	
	private void jbInit() {

		pnlMain.setBackground(c);
		pnlMain.add(treeTemp);
		treeTemp.addMouseListener(new MouseListener(){

			@Override
			public void mouseClicked(MouseEvent arg0) {
				// TODO Auto-generated method stub
				TreeNode node = (TreeNode)treeTemp.getSelectionPath().getLastPathComponent();
				if(node.isLeaf()) {
					System.out.println(node.toString());
				}
			}

			@Override
			public void mouseEntered(MouseEvent arg0) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void mouseExited(MouseEvent arg0) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void mousePressed(MouseEvent arg0) {
				// TODO Auto-generated method stub
				
			}

			@Override
			public void mouseReleased(MouseEvent arg0) {
				// TODO Auto-generated method stub
				
			}
			
		});
		this.add(pnlMain);
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		TestTree tt = new TestTree();
		tt.setSize(300, 200);
		tt.setLocation(300, 200);
		tt.setVisible(true);
	}

}

If selected node is leaf, it will print out the node's information.

public boolean isLeaf()
Returns true if this node allows children. Whether the node allows children depends on how it was created。
用着个就可以
