Entity Beans Without Create Methods
If an entity bean is never meant to be
created by a client, you can simply not implement a
create() method on the home interface. This means

privilege that might be reserved for the database administrator (they
wouldn’t want some crazed travel agent inserting random ships
into their cruise line).
