I know that in netscape, there is JSObject that can use applet to interface with javascript. How about IE? Can applet interfaces with it.
If so, how?

Netscape's JavaScript vs. Microsoft's JScript
Launching an HTML document from an applet
you need to use the showDocument and AppletContext, but there is a little thing. If you are
using both the browser Netscape and IE then you sure need to do something in addition.
 add "MAYSCRIPT" in the <applet> tag
to let IE understand that you are asking the browser to do something.
This is because the JavaScripts are netscapes production, and other browser needs to know that
there will be some browser interaction.

The code:

[Java applet]

import java.applet.*;

public class inJava extends Applet{
  public void init(){
    String msg = "We will jump to a URL, you can further make that when
clicked in list or so, it goes to the URL as done in next line of code";
    try {
        (new URL("javascript:doAlert(\"" + msg +"\")"));
 (new  URL("javascript:jumpTo(\"\")"));
    catch (MalformedURLException me) { }

[Javascript and HTML]

function doAlert(s) {
function jumpTo(tag) {
<APPLET CODE="inJava.class"  
        NAME="myApplet"  MAYSCRIPT
        HEIGHT=400 WIDTH=10>
