Category getCategory(Integer categoryId) —to the interface. Then, we can con-
tinue coding without worrying about the implementation.
When the viewCategory method completes, it uses a public static String called
SUCCESS as the return value. The value of the SUCCESS variable is success . The
returned String is used to provide the BeanAction with the name of the action for-
ward to call. This results in our JSP display (see listing 14.10).
