How to implement Frames in Xhtml?

I tired to implement Frames in xhtml in eclipse

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head>
<title>Frameset Document</title>
</head>

<frameset cols="20%,80%">
<frame src="Menu.htm" />
<frame src="Home.htm" />
</frameset>

</html>

and it shows the HTTP Status 404.. Could you please tell me how to get rid of this error?

There probably is a way, although I would prefer if there weren't. Frames went the way of the dodo years ago (as did XHTML, actually, for most practical purposes). There are most likely better ways of achieving what you're trying to do.

A 404 is the bad use of a URL that references a non-existent resource.

And yeah, frames are rather a dinosaur.

Thank you.

I think that frames get too little respect, but JSF doesn't play well with frames, regardless.
