Web Browser and javascript

Question

Hi, i've been looking for a solution to my problem in last 2days but i still can't find one.
I'm able to display a html page properly by using a JEdtiorPane and the setPage(URL url) method but still, neither javascript nor java applets run.
I get the raw code of html displayed but no interpretation of it.
Is there any way to execute it???
Here is the code :
import java.awt.*;
import java.net.*;
import javax.swing.*;
import javax.swing.event.*;
import java.beans.*;

public class Connexion
    extends JPanel {
  private JEditorPane jep;
  private int type, num, var;
  private URL url, historique[];
  Connexion() {}
  Connexion(String urlString) {
    super();
    historique = new URL[20];
    num = 0;
    jep = new JEditorPane();
    openURL(urlString);
    jep.setEditable(false);
    jep.addPropertyChangeListener(new PageChangeListener());
    jep.setContentType("text/html");
    setBackground(Color.white);
    jep.addHyperlinkListener(new LinkActivator());
    add(jep);
  //M�thode d'ouverture de l'url ou de modification de l'url pour ouverture
  protected void openURL(String urlString) {
    try {
      url = new URL(urlString);
      jep.setPage(url);
    catch (Exception e1) {  }
}I don't want to use external component such as ie or netscape as can be seen in other post.
Hot java does it but i can't find how.
Sure u guys can do it.
Thx

Ah, but then how can you consider using JEditorPane, or URL or String, or any other pre-made classes? ;-) Usable web browsers are very very complicated, not something an inexperienced programmer can write on his/her own in one afternoon.
For executing JavaScript you need a JavaScript interpreter. I know of one called Rhino but I don't know how easy it will be interfacing it and the DOM model of the web page: http://www.mozilla.org/rhino/
For executing Java applets you need to first install a security manager that restricts the applet to a sand box. Then you load the applet class dynamically, instantiate it, and set its AppletContext (you must implement the AppletContext interface to do this). I know this is a bit vague but it will be clearer once you start working on it.
