Passing javascript callback to java applet deployed using deployJava

I have an applet which is pretty long to start, but which is needed for my application to work.

I used to register a javascript callback : jsAppletIsStarted. This callback was called at the end of execution of the applet's start method.

The code looked more or less like this:

<script>
var jsAppletIsStarted = function(){/*do some useful stuff*/};
</script>
<applet id=".." etc>
<param name="appletStartedCallBack" value="jsAppletIsStarted "/>
</applet>

And it worked like a charm.

I had to switch to another way to start the applet : using the deployJava.runApplet() method.

The code now looks like this:

    <script>
    var jsAppletIsStarted = function(){/*do some useful stuff*/};

    var attributes = {};

 attributes.code = "myAppletClass.class";
 attributes.codebase="myCodeBase";

 var parameters = {};
 parameters.appletStartedCallBack="jsAppletIsStarted " ;

 var version = '1.6' ;
 deployJava.runApplet(attributes, parameters, version);
   </script>

And the callback is no more recognized. In my java console, I have the following error.

12:26:24,655 ERROR  com.mypackage.JavaScriptCallBack     -

Is there a hack to pass the javascript callbacks as parameters to the applet for using with deployJava.js ?

Please try calling the function manually.

getAppletContext().showDocument(new URL("javascript:jsAppletIsStarted()"));
