I am new to JPA. I have to migrate a JDBC application to JPA. For a
certain class there are some extra fields in the table that are not in
the class itself. (For example creation time, modification time and
user that created the entity.) Is it possible to keep those fields in
the table and updated, without putting the values in the class?
