How can I get my JProgressBar to appear in my JPanel?

Question

I've been going over this code for ages, and have no idea how to get my JProgressBar to actually appear on the GUI. When I run the app, the JLabel appears in the JPanel, but the JProgressBar does not, how do I fix this?

(note: the JProgressBar does work and updates, it just doesn't appear on the GUI)

jPanel9.setLayout(new BorderLayout());
    jPanel9.add(new JLabel(theTask.getName() + theTask.getDes()), BorderLayout.NORTH);
    JProgressBar progress = new JProgressBar(0, theTask.getMax());
    progress.setStringPainted(true);
    progress.setBorderPainted(true);
    progress.setValue(theTask.getProgress());
    progress.setString(theTask.getProgress() + "/" + progress.getMaximum());
    progress.setPreferredSize(new Dimension(100,100));
    progress.setVisible(true);
    jPanel9.add(progress, BorderLayout.SOUTH);
    jPanel9.revalidate();
    jPanel9.repaint();

    System.out.println(progress.getString());
    System.out.println("Progress: " + theTask.getProgress());
    System.out.println("Max: " + theTask.getMax());

Add more code, a [SSCCE](http://www.sscce.org/). Maybe you're not setting correctly the properties of the frame. — elias, Apr 20 '15 at 19:07
Is this code running in the AWT event dispatch thread like it's supposed to? — VGR, Apr 20 '15 at 19:46
@SubhanAhmed removing changes nothing, neither does having them. — rgollum, Apr 20 '15 at 19:49
It's all in Netbeans, jPanel9 was created using their JFrame editor view — rgollum, Apr 20 '15 at 19:49
Invoke `setVisible()` _after_ `add()` and `pack()`; avoid the GUI editor at this stage. — trashgod, Apr 20 '15 at 20:01

I resolved the issue by making a custom panel, and dropping it into my gui in place, not quite what I wanted, but it got the job done:

public class ProgressPanel extends javax.swing.JPanel {

/**
 * Creates new form ProgressPanel
 */
public ProgressPanel() {
    initComponents();
    jProgressBar1.setMinimum(0);
}

public ProgressPanel(int max, String s)
{
    jProgressBar1.setMinimum(0);
    jProgressBar1.setMaximum(max);
    changeLabel(s);
    initComponents();
}

public void setMax(int i)
{
    jProgressBar1.setMaximum(i);
}


public void changeProgress(int i)
{
    jProgressBar1.setValue(i);
    jProgressBar1.setString(i + "/" + jProgressBar1.getMaximum());
}


public void changeLabel(String s)
{
    jLabel1.setText(s);
}

/**

    setLayout(new java.awt.BorderLayout());

    jLabel1.setFont(new java.awt.Font("Tahoma", 0, 14)); // NOI18N
    jLabel1.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
    jLabel1.setText("jLabel1");
    add(jLabel1, java.awt.BorderLayout.PAGE_START);

    jProgressBar1.setFont(new java.awt.Font("Tahoma", 0, 14)); // NOI18N
    add(jProgressBar1, java.awt.BorderLayout.CENTER);
}// </editor-fold>
