i'm new to java and have a strange problem.
i create some folder(theme, js, css) in WEB-INF folder and put my files to this folders.
in index.jsp i use a css file by following way:

```
<style type="text/css"> 
        <%@include file="WEB-INF/css/style.css" %>
 </style>

```

it works good.
but in style.css file i have a div tag that set a background for header tag by following way:

```
#header{
background: url(../theme/violet/header.jpg) repeat-x;
}

```

oh. my problem is here. it doesn't work. since other css command work very good.
i know that WEB-INF detail aren't accessible but may there is a way like the way that i use for link style.css in my index.jsp page.

any solution?
thanks.
