1. Global cursor: To change the cursor in a application wide fashion, you have to access the Glass Pane and set its cursor, and then make the glass pane visible – otherwise, it has no effect at all:
   

   int cursorType = Cursor.S_RESIZE_CURSOR;
   Component glassPane = ((RootPaneContainer)someComponent.getTopLevelAncestor()).getGlassPane();
   glassPane.setCursor(Cursor.getPredefinedCursor(cursorType));
   glassPane.setVisible(cursorType != Cursor.DEFAULT_CURSOR);

   

   done.
