JasperReport HTML Report and JQuery

Hi, I'm working with PHP and I was able to show reports using JasperServer thanks to some libraries.

Now I have a issue with the HTML output of my reports, it always append in the HTML header this line:

<script type="text/javascript" src="/jasperserver/scripts/jquery/js/jquery-1.7.1.min.js"></script>

First of all, I didn't have the library in that route then I put it, but it causes conflict because I'm already using jquery(1.9) in my project.

So, I need your help to remove that script line.

Thanks.
