Ajaxed auto reload div troubleshooting

One of the most weird problems of all times…

With the aid of prototype.js, i added an ajaxed div auto-reloader on my page. It means that, instead of auto refreshing the whole page, thanks to this script, i can make auto-refreshed each minute one of the divs. Now I want to do it for the published posts listing. In other words, I want to the the titles (with their links of course) of the recent posts in a div which will be auto reloded each minute.

Now… The problem is that the script that i use obliges me to use a php include structure to do it. And when I try to applicate, it gives me this: “Fatal error: Call to undefined function: have_posts() in /nfs/c02/h07/mnt/39816/domains/verkac.com/html/feed/wp-content/themes/default/news.php on line 1” …

Let me paste the script here:

<script src="https://www.verkac.com/feed/wp-content/themes/default/prototype.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">

var count = 0;

function test() {
var myAjax = new Ajax.PeriodicalUpdater(
'content', // div to update
'https://www.verkac.com/feed/wp-content/themes/default/news.php',
{
method: 'get', // HTTP
evalScripts: true, //
frequency: 2, //
decay: 0 //
}
);
}

test(); //run without click

</script>

And in the body part, I have this:

<div id="content">
<?php include('news.php'); ?>
</div>

I think that I must create a new root file which I should call news.php but I don’t know how to do it. I tried to hack wp-blog-header.php, template-loader.php etc. It doesn’t work.

Are there anyone who know to create a second root file besides index.php?

Thanx a lot…
