JTree same nodes

Question

Hy,
I have a problem with the treeselectionlistener.
I want to show data from a database using a JTree but the problem is that some nodes have the same name. So the methode
public void valueChanged(TreeSelectionEvent event){
                              TreePath path = tree.getSelectionPath();
     String test = path.getLastPathComponent().toString();
gives a lot of times the same value.
Is there a possibility to identify the selected node like an array that shows the number of the selected node.
Like [2,5,1] this would than mean node 2 of first row node 5 of second row and first node of 3th row?
Thx Mette

Answer 1

you could extend DefaultTreeNode and add a variable which will correspond to Key Field in your table like:
public class MyCustomTreeNode extends DefaultTreeNode {
private int nodeId;
//code if needed
or you could play with TreePath object... more on:
