sequence not generated for postgres using toplink jpa



This sequence generator code is not working properly

@SequenceGenerator(name=3D"catalog_seq_gen", sequenceName=3D"catalog_seq",
allocationSize=3D1)
@Id @GeneratedValue(strategy =3D GenerationType.SEQUENCE,generator =3D
"catalog_seq_gen")
@Column(name =3D"catalog_id", nullable =3D false)
private Long catalogId;

@Column(name =3D "CATALOG_NAME", nullable =3D false)
private String catalogName;
@Column(name =3D "CATALOG_DESC")
private String catalogDesc;=20


I have 3 fields in the code and toplink is generating the query wrongly

Exception in thread "main" javax.persistence.PersistenceException:
javax.persistence.PersistenceException: Exception [TOPLINK-4002] (Oracle
TopLink Essentials - 2.0 (Build SNAPSHOT (06/04/2007))):
oracle.toplink.essentials.exceptions.DatabaseException
Internal Exception: org.postgresql.util.PSQLException: ERROR: null value
in
column "catalog_id" violates not-null constraint
Error Code: 0
Call: INSERT INTO CATALOG (CATALOG_NAME, CATALOG_DESC) VALUES (?, ?)
bind =3D> [Description, null]



ideally it should generate=20

INSERT INTO CATALOG (CATALOG_ID, CATALOG_NAME, CATALOG_DESC) VALUES
(?,?,
?)
bind =3D> [1, Description, null]



I am using Oracle TopLink 11g: Technical Preview 3=20

what could be the reason?
