- * Both of the approaches defined in the JPA have significant problems!!!

- * </p>
- * <p>
- * Using the String values of enums is fairly restrictive because in a Database
- * these values are usually truncated into short codes (e.g. "A" short for

- * You can use this annotation to control the mapping of your enums to database
