ho fatto questo:
Codice PHP:
        try{
            String driver = "org.apache.derby.jdbc.EmbeddedDriver";
            Class.forName(driver).newInstance();

            String protocol = "jdbc:derby:zmovies;";
            Connection c = DriverManager.getConnection( protocol );

            Statement exe = c.createStatement();
            ResultSet rs = exe.executeQuery("SELECT * FROM movies;");
            ResultSetMetaData m = rs.getMetaData();
            
            DefaultTableModel model = new DefaultTableModel();
            JTable jTable1 = new JTable(model);

            // Aggiungi le colonne "manualmente"
            model.addColumn("ID");
            model.addColumn("Titolo");
            model.addColumn("Genere");
            model.addColumn("Anno");
            model.addColumn("Regista");
            model.addColumn("Attori");
            model.addColumn("Copertina");
            model.addColumn("Conservato in");

            // Aggiungi le righe leggendo dal db;
            while(rs.next()) {
              Vector<String> row = new Vector<String>();
              row.addElement(rs.getString("ID"));
              row.addElement(rs.getString("Titolo"));
              row.addElement(rs.getString("Genere"));
              row.addElement(rs.getString("Anno"));
              row.addElement(rs.getString("Regista"));
              row.addElement(rs.getString("Attori"));
              row.addElement(rs.getString("Copertina"));
              row.addElement(rs.getString("Archivio"));

              model.addRow(row);
            }

            rs.close();
            exe.close();
            c.close();
        }
        catch (ClassNotFoundException e){ System.out.println(e); }
        catch (SQLException e){ System.out.println(e); }
        catch (InstantiationException e){ System.out.println(e); }
        catch (IllegalAccessException e){ System.out.println(e); }
    } 
quando eseguo però non viene mostrata la tabella.

domanda: row.addElement(rs.getString()) prende tutti i risultati e li converte in stringhe anche se vengono da campi di diverso tipo?
