Calling a JavaScript function from an JApplet...

Question

Can anyone help? Is it possible to call a JavaScript function from within a JApplet? If so, what is the syntax? I've seen reference to the Netscape package but I've been led to believe it doesn't always work within Internet Explorer 6 which is the target browser.
If the above is not possible can anyone tell me if and how it is possible to load images from outside the init() method of a JApplet? This would allow me to work around the problem.
Thanks in advance - Jim.

Call javascript you use the JSObject
Please note the MAYSCRIPT int the html file.
html file:
     <object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
              height="0" width="0" >
        <param name="code" value="someApplet.class" />
        <!--[if !IE]> Mozilla/Netscape and its brethren -->
        <object classid="java:someApplet.class"
                height="0" width="0"
                mayscript=true>
        </object>
        <!-- <![endif]-->
      </object>
<LABEL id="lblOutputText">This text is the HTML text </LABEL>java class:
// new class for jsObject!!!! compile this: javac -classpath "C:\Program Files\Java\jre1.5.0\lib\plugin.jar" someApplet.java
// since jaws.jar does not exsist anymore
// in 1.4.0 to compile: javac -classpath "C:\j2sdk1.4.0_03\jre\lib\jaws.jar" someApplet.java
// for msjvm use the -source 1.3 -target 1.1 option so the command looks like this:
// javac -source 1.3 -target 1.1 -classpath "C:\j2sdk1.4.0_03\jre\lib\jaws.jar" someApplet.java
import netscape.javascript.*;
public class someApplet extends java.applet.Applet {
    JSObject win;
    public void init() {
         try{
             win = JSObject.getWindow(this);
// you need win.eval("window.close();"); // to close the window. if the current window is not a popup
// opened by a parent with window.open than the user will get a waring, your next question probably will
// be "can I stop this warning" and the answer is simple: NO
             JSObject textBoxLabel = (JSObject) win.eval("document.getElementById('lblOutputText')");
             textBoxLabel.setMember("innerHTML", "<center><h1>Some text</h1></center>");
        }catch(Exception e){
             e.printStackTrace();
