JFrame Content not showing

[NerdNum]

Hi

I have created a simple JFrame class (called ProgressWindow) that contains a label and a progress bar. Using a simple test program I am able to show the frame and update the progress bar from 0 to 100%. It worked fine.

I want to use the ProgressWindow in another application called SMSApplication. The SMSApplication calls a non-windowed class called ModemConnector. The ModemConnector is the class calling the ProgressWindow to show the progress of deleting messages stored on a GSM modem. However when the ModemConnector calls the ProgressWindow, the JFrame shows, but not the label or the progressbar. I have searched far and wide am not able to find a solution. Can someone please help.

I used Netbeans to create a JFrame form. Below is the code.

package javasms;

import java.awt.Dimension;
import java.awt.Toolkit;

public class ProgressWindow extends javax.swing.JFrame {

    private int maximum;
    private int value;
    private String label;

    public ProgressWindow(String title) {

        initComponents();
        
        setTitle(title);

        Dimension dim = new Dimension();
        dim.width = 360;
        dim.height = 100;

        setSize(dim);

        dim = Toolkit.getDefaultToolkit().getScreenSize();
        int xSize = getHeight();
        int ySize = getWidth();

        int posX = (dim.height - xSize)/2;
        int posY = (dim.width - ySize)/2;

        setLocation(posY, posX);
       

    }

    public void setVisisble()
    {
        setVisible(true);
        //progressBar.revalidate();
        //progressLabel.revalidate();
    }

    public void close()
    {
        setVisible(false);
        dispose();
    }

    public void updateProgressBar(int val)
    {
        setValue(val);
        progressBar.revalidate();
    }

    public void updateProgressLabel(String lbl)
    {
        setLabel(lbl);
        progressLabel.revalidate();
    }

    public void setLabel(String lbl)
    {
        label = lbl;
        progressLabel.setText(lbl);
    }
    
    public String getLabel()
    {
        return label;
    }

    public void setMaximum(int max)
    {
        maximum = max;
        progressBar.setMaximum(max);
    }

    public int getMaximum()
    {
        return maximum;
    }

    public void setValue(int val)
    {
        value = val;
        progressBar.setValue(val);
    }

        progressLabel.setText("progress");

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(

    }

    // Variables declaration - do not modify
