In JPA you should add some annotations about the type of inheritence. 

@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "USER")
@Entity
public class User ...

@Table(name = "PART_TIME_USER")
@Entity
public class PartTimeUser extends User ...

P.S. The @Table annotation is not necessary. Nevertheless I prefer to define it. It makes the code and its connection to database objects more readable.
