Highlight root node in jtree

Question

When I build my JTree, I have just one single node, the root node. So in order to highlight it, I basically do setSelectionRow(0);, however this is not highlighting the node as if a user clicked it with a mouse, WHEN THE APPLICATION COMES UP.
Once the application comes up, if I click on that node or for that matter any other node, they get highlighted in blue. It's only upon initialization that this doesn't work.
Here's a snippet of the sample code:
tree = new JTree();
tree.setCellRenderer(new RateManagerTreeCellRenderer());
I've also tried the setSelectionPath(TreePath path) method without any success. I think that my Custom TreeCellRenderer could be the culprit. If someone could try to duplicate this problem by using the code below of my RateManagerTreeCellRenderer, I would appreciate it.
public class RateManagerTreeCellRenderer extends DefaultTreeCellRenderer
private static Color oldColor = Color.BLACK;
private static Color newColor = Color.BLUE;
private HashMap iconMap = new HashMap();
public Component getTreeCellRendererComponent(
          JTree tree, Object value,
          boolean selected, boolean expanded,
          boolean leaf, int row,
          boolean hasFocus)
super.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, hasFocus);
DefaultMutableTreeNode treeNode = (DefaultMutableTreeNode)value;
Object userObject = treeNode.getUserObject();
if (userObject instanceof NameAndID)
NameAndID nameAndID = (NameAndID)userObject;
int count = nameAndID.getItemCount();
if (count > 0 && !selected)
setForeground(newColor);
else if (!selected)
setForeground(oldColor);
this.setToolTipText(((NameAndID)userObject).toString());
String type = nameAndID.getType();
setIcon(type);
return this;
}

Do you mean setting the focus on that node? Or are you talking about some custom painting to put a background behind it? We can't help you much if you don't ask a more specific question with more details about what you're trying to do.
