How do I prepend <%= request.getContextPath() %> to all relative URLs inside a jsp page?

Question

The subject says it all, almost. How do I automatically fix jsp pages so that relative URLs are mapped to the context path instead of the server root? That is, given for example

<link rel="stylesheet" type="text/css" href="/css/style.css" />

how do I set-up things in a way that maps the css to my-server/my-context/css/style.css instead of my-server/css/style.css? Is there an automatic way of doing that, other than changing all lines like the above to

<link rel="stylesheet" type="text/css" 
      href="<%= request.getContextPath() %>/css/style.css" />
