Can't close JFrame, from click inside JPanel

Question

I have the following situation:

I have a JFrame(GridBagLayout) with 3 JPanels in it (headerPanel, bodyPanel, footerPanel); On the bodyPanel I have a login button; What I want, is to close the JFrame, an open another one;

Main:

package com.system.reservation.airline;

public class Main {
    public static void main(String[] args) { // Main function that executes the program
        LoginPage loginPage = new LoginPage();
    }
}

LoginPage:

public class LoginPage extends JFrame{
    HeaderPanel headerPanel = new HeaderPanel();
    BodyPanel bodyPanel = new BodyPanel();
    FooterPanel footerPanel = new FooterPanel();

    public LoginPage(){ // Constructor
        this.setTitle("Login"); // Frame title
        this.setSize(400, 600); // Frame size
        this.setLocationRelativeTo(null); // Center frame, when launched
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // Frame function, on close button (will close)
        this.getContentPane().setBackground(new Color(240,248,255)); // Light blue
        this.setLayout(new GridBagLayout());

        GridBagConstraints gbc = new GridBagConstraints();

        gbc.weightx = 1;
        gbc.weighty = 1;
        gbc.fill = GridBagConstraints.BOTH;

        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.gridheight = 1;
        this.add(headerPanel, gbc);

        gbc.gridx = 0;
        gbc.gridy = 1;
        gbc.gridheight = 1;
        this.add(bodyPanel, gbc);

        gbc.gridx = 0;
        gbc.gridy = 2;
        gbc.gridheight = 3;
        this.add(footerPanel, gbc);

        this.pack();
        this.setVisible(true); // Frame visible
    }
}

BodyPanel:

package com.system.reservation.airline.panels;

import com.system.reservation.airline.HomePage;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class BodyPanel extends JPanel implements ActionListener { // Listens to events

    JButton login_button;
    JTextField userName_txb, password_txb;
    JLabel tokenResponse;

    String username;
    String password;

    public void setUsername(String newUsername){
        username = newUsername;
    }
    public String getUsername(){
        return username;
    }

    public void setPassword(String newPassword){
        password = newPassword;
    }
    public String getPassword(){
        return password;
    }
    public BodyPanel(){
        Color transparent = new Color(1f,0f,0f,0f);

        this.setBackground(transparent);
        this.setLayout(new BorderLayout());
        //this.setBorder(BorderFactory.createLineBorder(Color.green, 3));

                            // CLOSE JFRAME
                            System.out.println("It matches!");
                            HomePage homePage = new HomePage();
                            break;
                        }
                    }
                }catch(Exception e2){
                    e2.printStackTrace();
                }
            }
        }
    }
}

After I click login the JFrame on the left shows up. I want to close the one on the right.

Any help would be appreciated, thanks.

Answer from @camickr, managed to close Jframe, from click inside Jpanel:

login_button = (JButton) e.getSource();
SwingUtilities.windowForComponent(login_button).dispose();
