NOOOO!
Please don't start your JavaScript career with browsersniffing.
It has been damned, cursed, and thrown down the toilet (and flushed)
some years ago.

Warning: If you visit comp.lang.javascript, don't even mention it,
unless you love flames.

Instead of branching your code for different browsers using sniffing, a
much better approach exists: capability testing.
An age-old example: You want to change some images on your webpage?
Check if the images exist before trying to:
if (document.images) {
// do your stuff
} else {
// forget it. Browser doesn't support images.
}

Browsersniffing is very unreliable.
Always ask for in comp.lang.javascript if you think you must use
browsersniffing. They will almost always suggest a better solution.

Aha. Well, in that case Flash might be a better option for you.
If I were you I would pick the solution (JavaScript, Flash, Java applet)
that best fits your competence.

I didn't want to push you to browsersniffing.

Good choice.
Personally I quited J2EE/Tomcat a few years back in favor of PHP.
Java is the most beautifull language I ever saw, but I deliver maybe 2-3
times quicker in PHP.
So if my clients don't care how I solve thier problem, then I solve it
in PHP. ;-)
