Using a JavaScript function as a listener

Question

Problem with the original Java plug-in system. Most all my customers are forced to use the original Java plug-in (not the Next-Gen). So, I need a solution that works for the original please.
JavaScript:
applet.addActionListener({
    actionPerformed: function(evt) {
        alert("Heard the event!\n" + evt.toString());
Java Applet (snippet):
private JButton pushButton;
public void addActionListener(final JSObject jsl) {
    // Wrap the JSObject in an ActionListener.
    ActionListener l = new ActionListener() {
        public void actionPerformed(ActionEvent evt) {
            jsl.call("actionPerformed", new Object[] { evt });
    // Add the JS listener to the button so it gets informed of clicks.
    pushButton.addActionListener(l);
}This works fine if I could use the Next-Gen plug-in, but as I mentioned earlier, I am prohibited from using that.
Oddly enough, this code seems to work in IE, but it fails in Firefox. In Firefox while the JSObject itself is not equal to null, calling "toString()" on it returns "null". Thus, the call to "call(...)" does nothing and the JS function is never called.
In IE, it may be necessary to use a full-fledged class to store the reference to the JSObject. The "final" keyword should preserve it, but sometimes it doesn't.
public class JSActionListener implements ActionListener {
    private final JSObject jsObj;
    public JSActionListener(JSObject jsObj) {
        this.jsObj = jsObj;
    public void actionPerformed(ActionEvent evt) {
        jsObj.call("actionPerformed", new Object[] { evt });
public void addActionListener(final JSObject jsl) {
    // Wrap the JSObject in an ActionListener.
    ActionListener l = new JSActionListener(jsl);
    // Add the JS listener to the button so it gets informed of clicks.
    pushButton.addActionListener(l);
}

I'm such a moron. I never put in a trace command to see if
the last line of my shrink command was getting executed. It turns
out the movie doesn't scale perfectly to 16.5 but instead goes to
16.49etcetc. As a result that last line wasn't being executed. Now
everything works. But I was wondering if you guys could think of a
nice way to compartmentalize all of this code, like maybe store it
all in a variable or something, so I can attach it to several
different movie clips?
