Java swing popupmenu / context menu does not appear in secondary monitor

Question

Main screen left
second screen right
swing portal application is visible on two screens.
If you open a context menu (right mouse) on the right screen, the context menu open on the left (Main) screen instead of the right.

Answer 1

Thank you very much for the replying.
The below are my use cases :
1. JDK 7 used.
2. OS - Ubuntu/windows XP/2008
3. Tested with extending more than 1 monitors, i.e. Laptop / primary monitors are attached with other secondary monitors attached and then running swing portal        application.
4. This happens when you use "Extended Desktop" with two screens.
    Main screen left
    Second screen right
    Portal is visible on two screens.
    Open a context menu (right mouse) on the right screen, the context menu open on the left (Main) screen instead of the right
The below is the sample of code of the file that actually open up the popups. The bold italics methods are the call hierarchy that are responsible to finally call the showPopupMenu().
private synchronized void handleMouseEvent( final IDirNodeMouseEvent e ) {
        if ( e.getMEvent().isPopupTrigger() ) {
            Thread thread = new Thread(
                    new Runnable() {
                        public void run() {
                            JNDITreeNode node = (JNDITreeNode) e.getNodeAtEventLocation();
                            System.out.println(" --- handleMouseEvent ---");
                            createPopupMenu(e.getMEvent().getPoint(), e.getMEvent().getComponent(), node);
            thread.start();
private synchronized void createPopupMenu(final Point point, final Component c, JNDITreeNode node) {
        contextMenuDN = node.getDn();
        CursorHelper cursorHelper = CursorHelper.showWaitCursor(c);
        com.marconi.platform.cvb.bcmp.security.AbstractDNPanel.registerJndiTreeNode(node);
        ContextMenuFactory contextMenuFactory = new ContextMenuFactory ( context );
        contextMenuFactory.setAttributeViewDisplayText(node.getDisplayText());
        TreeNodeDescriptor treeNodeDescriptor = new TreeNodeDescriptor(
                node.getDn(),
                node.getDirData()
        boolean searchContextAvailable = true;
        JNDIData data = node.getDirData();
        Attributes attrs = data.getAttributes();
        Attribute a = attrs.get("mSearchContextAvailable");
        try
          if (a != null)
                String value = (String)a.get();
                if (value.equalsIgnoreCase("FALSE"))
                    searchContextAvailable = false;
        catch (NamingException ne)
        jMenuItemSearch.setEnabled(searchContextAvailable);
        JPopupMenu menu = contextMenuFactory.getPopupContextMenu( treeNodeDescriptor );
        menu.addSeparator();
        menu.add( jMenuItemCollapseAll );
        menu.add( jMenuItemSearch );
        if ( contextMenuDN != null ) {
            menu.add(jMenuItemUpdate);
        MUtils.showPopupMenu(menu, point, c);
        cursorHelper.showDefaultCursor();
   * MUtils ensures that the whole popup menu is visible, performs a cleanup before showing.
   * @param popupMenu the menu to be shown
   * @param mouseClickPoint where the mouse has been clicked
   * @param c the component on which to show the popup menu
   * @see cleanupMenu
    public static void showPopupMenu( final JPopupMenu popupMenu, final Point mouseClickPoint, final Component c) {
    if ( popupMenu.getComponentCount() == 0 ) return;
    cleanupMenu( popupMenu );
    if ( autoAssigningMnemonics ) {
      assignMnemonics( popupMenu );
    final Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    final Point result = new Point(mouseClickPoint);
    SwingUtilities.convertPointToScreen( result, c);
    Dimension popupSize = popupMenu.getPreferredSize();
    popupSize.height = popupSize.height + 30; // as Windows TaskBar is overlapping always
      if ( popupSize != null ) {
      if ( result.getX() + popupSize.getWidth() > screenSize.getWidth() ) {
        result.setLocation( screenSize.getWidth() - popupSize.getWidth() , result.getY() );
      if ( result.getY() + popupSize.getHeight() > screenSize.getHeight() ) {
        result.setLocation( result.getX(), screenSize.getHeight() - popupSize.getHeight() );
    result.x = Math.max( 0, result.x );
    result.y = Math.max( 0, result.y );
    SwingUtilities.convertPointFromScreen( result, c );
    javax.swing.SwingUtilities.invokeLater(
      new Runnable() {
        public void run() {
            popupMenu.show( c, (int) result.getX(), (int) result.getY());
Please let me know your feedback. Need to confirm whether this issue is really exists or not.
