I'm new to hibernate and I'm using db-derby 10.7.1.1 and I have a little problem. I've got a database with 3 tables with data that I need and 2 tables that hibernate created for auto incrementation.

the thing is I need to populate a jtable with the data that I've got in one table but I'm getting an exception:
Hibernate: select cartemodel0_.codcarte as codcarte8_, cartemodel0_.Autor as Autor8_, cartemodel0_.imprumut as imprumut8_, cartemodel0_.titlu as titlu8_ from CarteModel cartemodel0_
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0 >= 0


the table name in the database is CarteModel and the columns are : codcarte-int auto increments, autor-String, imprumut-int, titlu-String

the code that I use to get the data from the data base is:

@SuppressWarnings("unchecked")
public List<CarteModel> ListaCarti(){
AnnotationConfiguration conn = new AnnotationConfiguration();
conn.addAnnotatedClass(CarteModel.class);
conn.configure();
SessionFactory sesiune = conn.buildSessionFactory();
Session ses = sesiune.getCurrentSession();
ses.beginTransaction();
Query query = ses.createQuery("from CarteModel ");

List<CarteModel> lista_c ;

lista_c = query.list();

ses.getTransaction().commit();
return lista_c;
}


and the code to put the data in the jtable is :

CarteRepository crtrep = new CarteRepository();
CarteTableModel crttblmdl = new CarteTableModel(crtrep.ListaCarte());
CarteController crtctrl = new CarteController();

tableModel = new DefaultTableModel();
table.setModel(crttblmdl);
table = new JTable(tableModel);
jScrollPane1.setViewportView(table);
table.setFillsViewportHeight(true);


please help
