I've written a JTree with couple of nodes. When I launch the program, I only see the node icons like folder or file and not the names associated with them. I could expand and collapse the nodes. When I debug, I see that the nodes are set with proper data whatever I used while building the model. In this program, i've written wrappers for JTree, TreeModel, DefaultMutableTreeNode. What could be the problem? Any pointers would be of great help.

I've found the issue. I didn't override the toString() method of the user object class. That was null. I just learnt that it needs to be overridden.
