How to position a browser inside another JFrame interface?

I was able to do this:

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.io.IOException;

import javax.swing.BorderFactory;
import javax.swing.BoxLayout;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;
import javax.swing.event.HyperlinkEvent;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.HTMLFrameHyperlinkEvent;

public class SwingHTMLBrowser extends JFrame {

    private JTextArea userStatus, serverStatus;
    private JPanel actions;


    SwingHTMLBrowser() {



        super("Swing HTML Browser");
        setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        setPreferredSize(new Dimension(600, 400));

        userStatus =  new JTextArea(5,5);
        JScrollPane userStatusPane = new JScrollPane(userStatus);
        userStatusPane.setBorder(BorderFactory.createTitledBorder("user Status"));
        userStatusPane.setPreferredSize(new Dimension(this.getPreferredSize().width/6, this.getPreferredSize().height));

        serverStatus = new JTextArea(5,5);
        JScrollPane serverStatusPane = new JScrollPane(serverStatus);
        serverStatusPane.setBorder(BorderFactory.createTitledBorder("server Status"));
        serverStatusPane.setPreferredSize(new Dimension(this.getPreferredSize().width/6, this.getPreferredSize().height));

        actions = new JPanel();
        actions.add(new JLabel("actions"));
        actions.setPreferredSize(new Dimension(this.getPreferredSize().width, 100));
        actions.setBorder(BorderFactory.createLineBorder(Color.red));

        add(actions, BorderLayout.NORTH);

        JPanel secondaryPane = new JPanel();
        secondaryPane.setLayout(new BoxLayout(secondaryPane, BoxLayout.X_AXIS));
        secondaryPane.add(userStatusPane);
        secondaryPane.add(serverStatusPane);
        secondaryPane.add(new Browser());

        add(secondaryPane, BorderLayout.CENTER);

        pack();
    }

    public static void main(String args[]) {

        SwingUtilities.invokeLater(() -> new SwingHTMLBrowser().setVisible(true));
    }
}

class Browser extends JPanel {

    private JTextField addressBar;
    private JEditorPane pane;

    public Browser() {
        setLayout(new BorderLayout());
        addressBar = new JTextField();
        pane = new JEditorPane();
        pane.setEditable(false);

        addressBar.addActionListener(e -> {
            String url = addressBar.getText();
            try {
                pane.setPage(url);
            } catch (IOException t) {
                t.printStackTrace();
            }

        });

        pane.addHyperlinkListener(evt -> {

            if (evt.getEventType() != HyperlinkEvent.EventType.ACTIVATED) {
                return;
            }

            JEditorPane srcPane = (JEditorPane) evt.getSource();

            if (evt instanceof HTMLFrameHyperlinkEvent) {
                HTMLDocument doc = (HTMLDocument) pane.getDocument();
                doc.processHTMLFrameHyperlinkEvent((HTMLFrameHyperlinkEvent) evt);
            } else {
                String url = evt.getURL().toString();
                addressBar.setText(url);
                try {
                    pane.setPage(url);
                } catch (Throwable t) {
                    t.printStackTrace();
                }
            }
        });
        add(addressBar, BorderLayout.NORTH);
        add(new JScrollPane(pane));
    }
}

Basically what I did was take advantage of the default layout manager of JFrame ( Borderlayout ), and use a sub-panel to be able to vertically distribute the 3 components, also taking advantage of the default layout of JPanel ( FlowLayout ) that organizes the components vertically, as shown in the figure.

Another modification is to create a class Browser , considering that it is an independent implementation.

Another important point to note is that all graphical applications involving the swing API should be dispatched to EDT .

The result comes out:
