Internet Explorer 'Stack Overflow at Line 0'
I'm getting some strange behavior when testing in IE code that worked fine on
Firefox. Version of IE is 6.0.
I'm using Geronimo 2.1.1, and whatever version of ActiveMQ comes with it,
though my own code references ActiveMQ 5.0.0 JARs. Anyway, it all seems to
work fine in Firefox 2.0, but when I load a virtual machine to try and test
on IE (my local machine is running Ubuntu 7.10, and is also running
Geronimo), I load the page, click a button to subscribe to a Queue, then
click a button to add a handler to receive messages, and that works. Shortly
after that, it'll come up with a message saying 'Stack overflow at line: 0',
which indicates to me that it may be a problem with the ActiveMQ Javascript
files.
Sometimes, rather than just showing one pop-up box, it'll show lots and
lots, like it's hit an infinite loop or something. I keep clicking them away
until I get the above message, at which point it won't receive any further
messages, even if I send them. Trying to receive them from Firefox works
fine, so if I send a message the ActiveMQ broker it will get it and send a
reply, but IE won't acknowledge the message. Firefox will, however.
Here's the page I'm using for testing.
<html>
<head>
<title>AJAX Testing Page</title>
<script type="text/javascript" src="amq/amq.js"></script>
<script type="text/javascript">amq.uri='amq';</script>
<script type="text/javascript">
/* Copyright Simon Willison (C) May 2004 */
function addLoadEvent(func)
{
var oldonload = window.onload;
if (typeof window.onload != 'function')
{
window.onload = func;
}
else
{
window.onload = function() {
if (oldonload)
{
oldonload();
}
func();
}
}
}
//addLoadEvent(onLoad);
function onLoad()
{
addHandler();
sendMsg();
}
var privateQueue = "queue.tmpq";
var tmp;
function rcvMessage(message)
{
alert("received " + message.firstChild.firstChild.nodeName + ";" +
message.firstChild.firstChild.firstChild.nodeValue);
privateQueue = message.firstChild.firstChild.firstChild.nodeValue;
alert("DONE");
}
function rcvPrivate(message)
{
alert("received " + message.nodeValue);
tmp = message;
}
function addHandler()
{
amq.addListener("ResponseQueue", "ResponseQueue", rcvMessage);
alert("handler added");
}
function sendMsg()
{
amq.sendMessage("RequestQueue", "<message>hello</message>");
alert("message sent");
}
function removeHandler()
{
amq.removeListener("ResponseQueue", "ResponseQueue");
alert("Removed Handler");
}
function receivePrivateMessage()
{
alert(privateQueue);
amq.addListener(privateQueue, privateQueue, rcvPrivate);
}
function removePrivateMessage()
{
amq.removeListener(privateQueue, privateQueue);
}
function sendTmp()
{
amq.sendMessage(privateQueue, privateQueue,
"<message>MESSAGE</message>");
alert("SENT");
}
</script>
</head>
<body>
<h1>Initial Heading</h1>
<input type="button" value="Request" onclick="sendMsg()" />
<input type="button" value="Receive" onClick="addHandler()" />
<input type="button" value="RemoveH" onClick="removeHandler()" />
<input type="button" value="Subpriv" onClick="receivePrivateMessage()" />
<input type="button" value="Rempriv" onClick="removePrivateMessage()" />
<input type="button" value="SendTmp" onClick="sendTmp()" />
</body>
</html>
The response from the server is always the same:
<response><private><queue>QUEUE{NANO}</queue></private></response>
Where Nano is the system time in Nanoseconds.
If anyone could shed some light on this it would be fantastic.

Re: Internet Explorer 'Stack Overflow at Line 0' (ActiveMQ
Javascript)
Posted by ipsi <nz...@gmail.com>.
Come on folks, surely someone has some idea what could be going on? I'm 99%
sure it's the fault of ActiveMQ.js, but I'm not sure why that would be the
case.
How many people out there are using the ActiveMQ Javascript stuff with IE?
Seems like I'm doing something wrong, but I'm basically stuck for ideas
right now.
Thanks,
