JTabbedPane with JScrollPane

Question

The application uses a JTabbedPane, each Tab contains a JScrollPane, the TopComponent contains the same Class with different Classes for the BottomComponent. Each BottomComponent is a separate class and relates to a different table. How can I interface with with the other classes without knowing which Tab is active?
