[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - identity fields in Entity beans

[cesar_takaide]

Hello, I'm new in EJB3 technology. I'm working with an entity bean that has a identity field, so i wrote this on the field declaration:

    @Id
    @Column(name = "codigo", nullable = false)
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long codigo;

But, when the entity is persisted, Jboss warns me with a message :

16:42:52,947 WARN  [WrappedConnection] Closing a result set you left open! Pleas
e close it yourself.
java.lang.Throwable: STACKTRACE

        at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.
...... etc...........

Why is this happening? Is something wrong in my code? Thank you very much for your help.
