I have a problem with the ID sequence generators (Oracle database).
I use Hibernate 3.1.
The Id column is so decrared:
Code:
@Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "RNSEQUENZ")
public String getRN() {
return RN;
}
public void setRN(String RN) {
this.RN = RN;
}
I have the sequence with this name, the SQL: "select RNSEQUENZ.nextval from dual" returns the next value of sequence.
But my application throws an exception:
Code:
Exception in thread "main" javax.persistence.PersistenceException: org.hibernate.AnnotationException: Unknown Id.generator: RNSEQUENZ
