I'm having the same problem. I tried what you suggested, but it isn't
working. All the documentation I have read says that @GeneratedValue only
works in conjunction with the @Id annotation, and this is exactly how my
program is reacting. I added a copy of the class where I am trying to
accomplish this below. Can you give me some pointers on what I'm doing
wrong, please?

@Entity
@Table(name = "Owner")
public class Owner {
        @Id
        @Column(name = "sysId")
        private String sysId;

        @GeneratedValue(strategy = GenerationType.IDENTITY)
        @Column(name = "number")
        private int number;

        public Owner() {
        }

        public String getSysId() {
                return sysId;
        }

        public int getNumber() {
                return number;
        }
}
