Allow right-click selection in a JTree

Question

Hi everybody! How are today? Fine? I hope so.
I've got a little question about JTrees: i want to put a right-click popup menu on my JTree, which may not be the same depending on which node of the tree is selected.
My problem is that i must do a left click selection of the node before doing the right click in order that this one may be effective and correct (i.e the correct popup menu appears).
So, i want to allow the right click selection in my JTree to select the node and to perform the action linked to the Popup menu.
I will be very thankfull if someone could help me :)

Sorry to post twice, but just thought i'd post the code to show you what I mean (forgive me not making this entirely generic):
///// Some "global" variables:
     private JPopupMenu               stPopupMenu;
     private TreePath               stPath;
     private String                    stPathComponent;
     private int                         stCount;
     private Object                    selectedNode;
///// Attaching the listeners:
symbolTreeDisplay.addTreeSelectionListener(stHandler);
symbolTreeDisplay.addMouseListener(stHandler);
//// The event listener class:
     private class SymbolTreeHandler extends MouseAdapter implements
               TreeSelectionListener
          public void mouseClicked(java.awt.event.MouseEvent event)
               try
                    if (event.getModifiers() == event.BUTTON3_MASK)
                    {//right button click on mouse
                         stPopupMenu = new JPopupMenu();
                         // add your logic here, based on selectedNode to add items to the menu
                         stPopupMenu.show(symbolTreeDisplay, event.getX(), event
                                   .getY());
               catch (Exception e)
          public void valueChanged(TreeSelectionEvent aTreeEvent)
               try
                    stPath = aTreeEvent.getPath();
                    stCount = stPath.getPathCount();
                    selectedNode = stPath.getPathComponent(stCount - 1);
               catch (Exception e)
     }
