Showing JList in a JPanel

Hey!

I'm currently making my very first GUI-application, and I need some help. I'm connecting my app to a local mySQL database on my laptop, and I'm having some problems displaying the results from a query made on the database.

Code:

---

                 
rs = stmt.executeQuery( "SELECT * FROM " +tingType+" WHERE navn='" +navn+ "'" );
                   
                    while(rs.next()) {
                            resultat.add(rs.getString("navn"));
                            resultat.add(rs.getString("BruktSist"));
                            resultat.add(rs.getString("lagringsPlass"));
                    }

---

Resultat is an ArrayList which I have defined earlier in the code. Now, the real problem is that when I try to display these results using a JList in a JPanel nothing gets display in the JFrame!

Code:

---

public class Resultat extends JPanel{

        private static final long serialVersionUID = 1L;
        private JList resultatListe;
       
        public Resultat(ArrayList<String> resultSet) {
                GridBagLayout gridBag = new GridBagLayout();
                GridBagConstraints gbc = new GridBagConstraints();
                setLayout(gridBag);
               
                JLabel resultat = new JLabel("Resultat:");
                resultatListe = new JList((ListModel) resultSet);
               
                gbc.ipadx = 10;
                gbc.insets = new Insets(5,5,5,5);
                gbc.anchor = GridBagConstraints.WEST;
               
                gbc.gridx = 0;
                gbc.gridy = 0;
                add(resultat, gbc);
               
                gbc.gridy = 1;
                add(resultatListe, gbc);
               
        }

If someone could tell me if I'm doing something wrong in displaying the JList in the JPanel, that would be awesome! :D

Thanks in advance.
