Sending/returning a string from a Java Applet to JavaScript

[Bary W Pollack]

Is it possible to have a Java Applet that is running on a web page to send/return a string (or an int) so that some JavaScript that is running on the same webpage can retrieve the information? If so, HOW?

Thanks!

Hi,

send/return a string (or an int) so that some JavaScript that is running

If the browser supports LiveConnect (IE and Netscape do), then it is
possible. See

This is very easy to do. The Java applet needs a public method which
returns a String and all Javascript has to do is call it. Here's The
Modern CA Author Javascript which does this in a setting with frames
where the applet may not even exist:
var mutatedRule = 'Press the "Test CA" button first'
var d = parent.frames["view"].document
var applet = d.applets[0]
if (applet) {
mutatedRule = applet.getRuleCurrentMutation()
}

Here's what the Java method looks like:
public synchronized String getRuleCurrentMutation() {
return RuleExport.toString(rule, rule.mutated != null ?
rule.mutated : rule.unmutated);
}
