UIManager.put( "TabbedPane.showTabSeparators", true );

Or for single tabbed pane with:

tabbedPane.putClientProperty( "JTabbedPane.showTabSeparators", true );

Selected Tab Background

Enable for all tabbed panes in application (JideTabbedPane and JTabbedPane) with:

UIManager.put( "TabbedPane.selectedBackground", Color.white );
