JSObject, how can I call JS function from Java Applet ?

Hi,
The code below working, but the calling JS not....and nothing happens , no error.
I did it with help from this side :
http://java.sun.com/j2se/1.5.0/docs/guide/plugin/developer_guide/java_js.html
Anybody know what is wrong?
Thanks!

HTML :

Java Applet

public void sendMsgUsingCall(final String method, final Object[] args) {
		//Parameter method is method in JavaScript, args are Parameters passing to the Method 
		System.out.println("HelloWorld.sendMsgUsingCall()");
		try {
			final JSObject win = JSObject.getWindow(this);
			win.call(method, args);
		} catch (final JSException ex) {
			aMessage.setText(ex.getMessage());
		}
	}

public void multipliStr(final String zahl1, final String zahl2) {
		boolean success = true;
		String mult = zahl1 + "  " + zahl2;
		aMessage.setText("DIe beide Zahlen sind :" + mult);
		final String sd1 = zahl1.toString();
		final String sd2 = zahl2.toString();
		try {
			d1 = Integer.parseInt(sd1);
			d2 = Integer.parseInt(sd2);

} catch (final NumberFormatException nfe) {
			System.out.println("NumberFormatException: " + nfe.getMessage());
			//aMessage.setText("NumberFormatException");
			success = false;
		}
		final int d3 = d1 * d2;
		mult += " = " + String.valueOf(d3);
		aMessage.setText("DIe beide Zahlen sind :" + mult);
		//call java Script side with JSObject
		final Object[] args = { mult };
		sendMsgUsingCall("getMsgFromJava()", args);
	}

What happens if you run this code? Are there any error messages, either from JavaScript or from Java?

Hi Ulf ,
I am sorry, I mixed up languages

I don't get any Error, on my TextFeld I see massege from :

DIe beide Zahlen sind :12 12
So this code part is not working :
"
and after this nothing happens...

thank you!

Not sure what's going on, but LiveConnect (the Java/JavaScript bridge technology) is notoriously fickle. I'd recommend to use the Common DOM API instead, if at all possible.

Hi,

On the first look I'd say that there could be two potential problems in your example/code:

1. I'm not sure, if you're calling the JSObject.getWindow in a right place
As far as I know, you should call it in Applets init() method.
Example:

2. Following code is missing in your HTML:

Hope this helps.

Regards,
Rok
