Browser doesn't show dynamically generated CSS in JSP

Question

I'm writing simple web app which generates simple CSS file for user.

I've mapped servlet for writing CSS on specific tag, and depending of the user's session attributes, I use PrintWriter for generating CSS stylesheet.

Problem: Stylesheet doesn't have any effect. Chrone shows it was downloaded (inspect element -> network), but it doesn't have any effect on my htmlpage.

In html, CSS is defined by: <link href="stylesheet.css" rel="stylesheet" type='text/css'>.
