Hello,

I would like to manage a table with JPA (NB6RC2,
GlassFishV2,Firebird1.5x, Jaybird-2.1.1):

public class Ugyfel implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@SequenceGenerator( name = "GEN_UGYFEL", sequenceName = "GEN_UGYFEL" )
@GeneratedValue( strategy = GenerationType.AUTO, generator = "GEN_UGYFEL" )
@Column(name = "ID", nullable = false)
private Short id;
@Column(name = "BOSSKOD")
…

When I want add a new record I've a following error message:

[TopLink Info]: 2007.11.27 10:54:46.557--Not able to detect platform

Have You got any ideas, how can I solve this problem?
