I noticed you are passing the name of the User object to the constructor of DefaultMutableTreeNode. This works, however, for renaming and IMO best practice dictates that you specify a custom User Object in the constructor of your node. The node will then use the toString method of your object for the node label.
subFolder = new DefaultMutableTreeNode(getUser(a));
And then assuming User's toString returns getName(), you're good. Anytime you want access to this object you can simple do:
User user = (User)node.getUserObject();
Then changing the name of 'user' will change the name of the nodes label.
