Can not display ImageIcon in a JLabel where you want in the code ???

Question

Hello, everybody. I need your help to solve a problem I am on it for 2 days now :
In the constructor of my class, I have a lot of initializing methods. If I try to display an image (with ImageIcon in a JLabel) within one of these methods, there is no problem and the image is correctely displayed. To try that, I use an image stored on my local disk in "c:\\".
public class Bedes extends javax.swing.JFrame {
public Bedes() {
initComponents();
-- further initializations
initConnection();
public void initConnection() {
try {
String driverName = "sun.jdbc.odbc.JdbcOdbcDriver";
Properties systemProperties = System.getProperties();
systemProperties.put("jdbc.drivers", driverName);
System.setProperties(systemProperties);
String dbURL = "jdbc:odbc:Bandes Dessin�es";
String strUtilisateur = "bedes";
String strMotDePasse = "cdle";
connectBedes = DriverManager.getConnection(dbURL,strUtilisateur,strMotDePasse);
catch (Exception e) {
System.out.println("Exception in DB Contact " + e);
// Here, I display an image in my JLabel, and it works :
couvertureAlbumString = "c:\\myImage.jpg";
couvertureAlbumsIcon = new ImageIcon(couvertureAlbumString);
couvertureAlbumsJLabel.setIcon(couvertureAlbumsIcon);
couvertureAlbumsJLabel.repaint();
}The problem is that I do not want to display these images there, but in a method that read some data's in a Database (with "try"-"catch" blocks). If there is a name of an image store in the DB, then it must be displayed in the JLabel (located in a JFrame -> JDeskTopPane -> JTabbedPane -> JPanel).
private void searchDetailsForAlbum(String albumsDetailsToSearch) {
String nomImageCouverture;
String couvertureAlbumString;
ImageIcon couvertureAlbumsIcon;
try {
PreparedStatement requeteDetailsAlbums = connectBedes.prepareStatement("SELECT * FROM bandes_dess WHERE bede_nom_tome = ?");
requeteDetailsAlbums.setString(1, albumsDetailsToSearch);
ResultSet resultatDetailsAlbums = requeteDetailsAlbums.executeQuery();
resultatDetailsAlbums.next();
collectionAlbumsJTextField.setText(resultatDetailsAlbums.getString(6));
genreAlbumsJTextField.setText(resultatDetailsAlbums.getString(9));
dessinateurAlbumsJTextField.setText(resultatDetailsAlbums.getString(10));
scenaristeAlbumsJTextField.setText(resultatDetailsAlbums.getString(11));
coloristeAlbumsJTextField.setText(resultatDetailsAlbums.getString(12));
prixAchatAlbumsJTextField.setText(resultatDetailsAlbums.getString(13));
// Here is the name of the Image to de read
nomImageCouverture = resultatDetailsAlbums.getString(14);
catch (Exception e) {
System.out.println("Exception in searchDetailsForAlbum" + e);
couvertureAlbumString = "c:\\";
// Here, I check if there is a name for a picture in the DB
if (!(nomImageCouverture.equals("No"))) {
// If Yes, I want to display it
couvertureAlbumString = couvertureAlbumString + nomImageCouverture;
couvertureAlbumsIcon = new ImageIcon(couvertureAlbumString);
couvertureAlbumsJLabel.setIcon(couvertureAlbumsIcon);
couvertureAlbumsJLabel.repaint();
}My JLabel is well displayed, but empty, without any image on it. WHY ???
MLK, you asked me to add some debug code. OK, with pleasure, but what is that "debug code" ???
Thanks a lot in advance if you could help me.
Christian.

Answer 1

DEBUG: couvertureAlbumString: c:\Aldebaran-La-Photo
OK, the extension of the file was NOT present !!!
I added it and ..... it works pretty good !!!
Thank you for your idea of the DEBUG.
Christian.
