Close the current UI and open another one

Question

Hello everyone,
I've got the following code and I want to close the current window and open another one. When i use "System.exit(1);" it closes everything when I use "this.dispose()" it doesn't close anything what could I try to get this to work? any suggestions?
the code is:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
//public class Equip_or_Job implements ActionListener {
public class Equip_or_Job extends Frame implements ActionListener {
    JFrame dFrame;
    JPanel jePanel;
    JButton choice;
    JComboBox jeqid = new JComboBox();
    public Equip_or_Job() {
        //Create and set up the window.
        dFrame = new JFrame("Work with Jobid or Equipid");
        dFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //Create and set up the panel.
        jePanel = new JPanel(new GridLayout(2, 1));
        dFrame.getContentPane().setLayout(new BorderLayout());
        //Add the widgets.
        addWidgets();
        //Set the default button.
        dFrame.getRootPane().setDefaultButton(choice);
        //Add the panel to the window.
        dFrame.getContentPane().add(jePanel, BorderLayout.CENTER);
        //Display the window.
        dFrame.pack();
        dFrame.setVisible(true);
Create and add the widgets.
    private void addWidgets() {
         //Create widgets.
          jeqid.addItem("Chose by Job");
          jeqid.addItem("Chose by Equipment");
          choice = new JButton("Chose");
            //Listen to events from the Convert button.
            choice.addActionListener(this);
          jePanel.add(jeqid);
          jePanel.add(choice);
    public void actionPerformed(ActionEvent event) {
          String sel = (String) jeqid.getSelectedItem();
        if("Chose by Job".equals(sel)){
               InsertNewDates inj = new InsertNewDates();
               //System.exit(1);
               dispose();
          else if("Chose by Equipment".equals(sel)){
               InsertNewDates ineq = new InsertNewDates();
               //System.exit(1);
               dispose();
Create the GUI and show it.  For thread safety,
this method should be invoked from the
event-dispatching thread.
    private static void createAndShowGUI() {
        //Make sure we have nice window decorations.
        try {
               UIManager.setLookAndFeel(
                    UIManager.getCrossPlatformLookAndFeelClassName());
          catch (Exception e) { }
        Equip_or_Job eorj = new Equip_or_Job();
    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
thanks in advance :o)

I'm not exactly sure what you want to do, but...:
dFrame.setVisible(false) hides the current Frame and the application is still running
