    Default How to populate a jPanel?

    Hello the Community,

    I try to display the result of a resultset in a JPanel but it does work.
    In a textArea it works. But the problem is you can write in it.

    Thank you for your advice.

    [CODE]
    private void intEmployeeNbrFocusLost(java.awt.event.FocusEvent evt) {
    searchPerson();
    // TODO add your handling code here:
    System.out.println("TextArea -1:" + EmployeeNbr);
    try {
    Class.forName("net.ucanaccess.jdbc.UcanaccessDrive r");
    } catch (ClassNotFoundException ex) {
    Logger.getLogger(Ecran.class.getName()).log(Level. SEVERE, null, ex);
    }

    try {
    // establishing connection
    conn = DriverManager.getConnection("jdbc:ucanaccess://c:/Users\\hab\\Desktop\\Decisions1.accdb","","");
    } catch (SQLException ex) {
    Logger.getLogger(Ecran.class.getName()).log(Level. SEVERE, null, ex);
    }
    //JLabel lblFname, lblLname, lblPhoneNumber;

    PreparedStatement ps;
    int EmployeeNbr = Integer.parseInt(intEmployeeNbr.getText());
    try {
    System.out.println("TextArea 1:" + EmployeeNbr);
    String SQL = "SELECT * FROM Decisions where EmployeeNbr = ?";
    ps = conn.prepareStatement(SQL);
    ps.setInt(1 , EmployeeNbr);
    ResultSet rs2 = ps.executeQuery();

    System.out.println("TextArea 2:" + EmployeeNbr);

    while ( rs2.next()) {
    // String newValue = Double.toString(Math.floor(EmployeeNbr));
    int newDecNumber = (int)Math.floor(DecNumber);
    int newEmployeeNbr = (int)Math.floor(EmployeeNbr);
    int newPourcent = (int)Math.floor(Pourcent);

    long nelleValEmployeeNbr = new Double(newEmployeeNbr).longValue();
    long nelleValDecNumber = new Double(newDecNumber).longValue();
    long nelleValPourcent = new Double(newPourcent).longValue();

    System.out.println("NewValue:" + nelleValEmployeeNbr);
    String ListeSQL = (rs2.getString(1) + " " +nelleValEmployeeNbr + " " + nelleValDecNumber+ " "+ nelleValPourcent+"\n");
    jTextArea1.append(ListeSQL);
    jTextArea1.append(rs2.getString(1));

    System.out.println("panel:" + ListeSQL);
    }

    ps.close();
    }catch(SQLException e){

    JOptionPane.showMessageDialog(null, e);
    }

    There are only two things you can add or do in a JPanel (aside from event handlers). One is to add other components such as JTextAreas, JTextFields, JComboBoxes, JButtons, etc. The other thing you can do is paint by overriding paintComponent(). If you want to write text into a JPanel the best thing to do is to add a specialized Component that lets you do that.

    Regards,
    Jim
