261290 - JavaScript doesn't see Java applet's functions: MacOS X only

Status: RESOLVED DUPLICATE of bug 232652

(Core Graveyard :: Java: Live Connect, defect)

Description

[Mark Riordan]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7) Gecko/20040707 Firefox/0.9.2
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv: 1.7.3) Gecko/20040910

A web page containing a Java applet and JavaScript code to call a method in that
applet fails with:  "TypeError: document.[insert applet name here].[insert
method name here] is not a function."

This fails only under Mozilla on Mac OS X.  I have Mozilla 1.7.3 on Mac OS
10.3.5,  Java 1.4.2_05.  I downloaded this copy of Mozilla from mozilla.org only
about 4 hours ago, so it's the latest.

The same page works on many other platforms, including Firefox 1.0 Preview on
both Windows and Linux.  It even works on Safari 1.2.3 (Mac OS X).

My applet element looks like:

<applet code='LongRunningApplet2' width='100' height='30'
name='LongRunningApplet' archive='LongRunningApplet2.jar'></applet>

The JavaScript looks like:
   	try {
   		var bOK = document.LongRunningApplet.everythingIsOK();
   		document.getElementById("resultDiv").innerHTML = "Applet loaded OK";
   	} catch (e) {
   	   var msg="Call to applet failed: "+e;
   		document.getElementById("resultDiv").innerHTML = msg;
   	}

(This also fails in a real application; the URL mentioned above is a
stripped-down version for problem resolution.)

Reproducible: Always
Steps to Reproduce:
1. Go to http://people.stdnet.com/mark/mozilla-mac/StaticAppletElement.htm
2. Wait until the applet loads
3. Click Check Applet

Actual Results:  
This test page (designed specifically for this bug report) will say:
Call to applet failed: TypeError: document.LongRunningApplet.everythingIsOK is
not a function.  This is because an exception was thrown.
Remember, this fails only under MacOS.  

Expected Results:  
Rather than throwing an exception, the call should have succeeded.  This test
page  would then have read "Applet loaded OK".

The applet does run; it's just that JavaScript can't talk to it.

Also tested OK on Mozilla 1.7.3 on Windows 2000.  It really is MacOS-specific.

Java: LiveConnect bug, not JavaScript Engine -- reporter take note.
