JTree - how to change the Icon on each single leaf

Hi,
in my JTree I would like to change the leaf icon depending on the status that the entry currenty has.
Example:
....
ImageIcon leafIcon_nio = createImageIcon("images/nio.png");
renderer_nio = new TreeCellRenderer();
renderer_nio = new DefaultTreeCellRenderer();

for(int werke=0;werke<anz_werke.size();werke++){
      int i=0;
      category = new DefaultMutableTreeNode(anz_werke.elementAt(werke));
      top.add(category);
      while(i<V_KUNDENWERK.size()){
            if(V_KUNDENWERK.elementAt(i).equals(anz_werke.elementAt(werke))){
--------------->
                                if(V_erledigt.elementAt(i).toString().equalsIgnoreCase("Ja")){
                                        renderer_io.setLeafIcon(leafIcon_io);
                                }
                              else
                              {
                                        renderer_io.setLeafIcon(leafIcon_io);
                              }
--------------->
                  book = new DefaultMutableTreeNode("QST:"+(String)V_QEC_QST_NR.elementAt(i));
                  category.add(book);
            }
            i++;
      }
}

I know, it's wrong (it doesn't work) but I don't know how to change.
I got only all Icons changed but thats not the target.

Who can help me?

Hello mayankeagle,

SimpleCellRenderer is exactly what I was serching for.
Only Problem:
In the main application I implemented a ImageIcon with the path "images/io.png".
This image was found and shown when starting from the .jar File.
Now, with the same Path in the SimpleCellRenderer it is working in the eclipse environment and command line start but the Images were not when starting from .jar- File.

What's wrong?

Regards
