Create a new .htm file named Page1.htm, and paste the following code:Page1.htm

<head>
<script language="JavaScript">
function generateAppletOneEvent()
{
	alert("Script event function called for applet one.");
	window.document.EBAppletOne.generateEvent();

{
	alert("Script event function called for applet two.");	
	window.document.EBAppletTwo.generateEvent();

Compile the following Java source files:EBAppletOne.java

import java.awt.*;
import java.applet.*;
import java.util.*;

public class EBAppletOne extends Applet { 
  private Vector listeners;
  
  public void init() { 
    Label l = new Label();
    l.setAlignment(Label.CENTER);
    l.setText("This is applet one.");
    add(l);
  }
  
  public void generateEvent() { 
    try { 
      if (listeners == null)
        return;
      Enumeration e = listeners.elements();
      while (e.hasMoreElements()) { 
        EventObject eo = new EventObject(this);
        ((EBAppletOneListener)e.nextElement()).onEBAppletOneEvent(eo);
        System.out.println("Event fired from applet one:  "+eo.toString());
      }
    }
    catch (Exception ex) { 
      ex.printStackTrace();
    }
  }

  public void addEBAppletOneListener(EBAppletOneListener list) { 
    if (listeners == null)
      listeners = new Vector();
    listeners.addElement(list);
  }
  
  public void removeEBAppletOneListener(EBAppletOneListener list) { 
    if (listeners != null)
      listeners.removeElement(list);
  }
}

EBAppletTwo.java

import java.awt.*;
import java.applet.*;
import java.util.*;

public class EBAppletTwo extends Applet { 
  private Vector listeners;
  
  public void init() { 
    Label l = new Label();
    l.setAlignment(Label.CENTER);
    l.setText("This is applet two.");
    add(l);
  }

  public void generateEvent() { 
    try { 
      if (listeners == null)
        return;
      Enumeration e = listeners.elements();
      while (e.hasMoreElements()) { 
        EventObject eo = new EventObject(this);
        ((EBAppletTwoListener)e.nextElement()).onEBAppletTwoEvent(eo);
        System.out.println("Event fired from applet two:  "+ eo.toString());	
      }
    }
    catch (Exception ex) { 
      ex.printStackTrace();
    }
  }

  public void addEBAppletTwoListener(EBAppletTwoListener list) { 
    if (listeners == null)
      listeners = new Vector();
    listeners.addElement(list);
  }
  
  public void removeEBAppletTwoListener(EBAppletTwoListener list) { 
    if (listeners != null)
      listeners.removeElement(list);
  }

}

EBAppletOneListener.java

import java.util.*;

public interface EBAppletOneListener extends EventListener
{
	public void onEBAppletOneEvent(EventObject e);
}

EBAppletTwoListener.java

import java.util.*;

public interface EBAppletTwoListener extends EventListener
{
	public void onEBAppletTwoEvent(EventObject e);
}

Copy the resultant .class files to the same folder as the Page1.htm file.

NOTE: These files do not need to be on a Web server to demonstrate the problem.
In Internet Explorer, open Page1.htm.
Click the applet buttons to generate bean events. Only one of the applets or beans fires events to the Web page script handlers.
