Answer 1

You haven't posted the important bit: the Employee class.

But my guess is that your Employee class is using @GeneratedValue() without specifying the sequence to use. So, Hibernate uses its default name: hibernate_sequence.

You can supply a sequence name as part of the GeneratedValue annotation. eg.

@GeneratedValue(strategy=SEQUENCE, generator="employee_id_seq")
