Hi, I have same problem. I have 2 tables on Sybase Anywhere: @Entity public class Employee { @Id @GeneratedValue private Long Id;
private String name; ................... } @Entity @IdClass(EmpHourId.class) public class EmpHour { @Id private Long empId; @Id private Long cpo; } My relation is Employee.Id == EmpHour.EmpId. How I can implement it on JPA? I use Hibernate. Thanks, Haim Fridland. -- View this message in context: http://n2.nabble.com/%40OneToMany-%40ManyToOne%2C-Bidirectional%2C-Composite-Key-BUG-tp210672p532204.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
