I wrote a custom tag, that controls if user has got the required level 
to acces page, as this:

<user:access currentUser="${mb.currentUser}" pageLevel="2" />

The code of tag follows:

    public int doStartTag() throws JspException {
        JspWriter out = pageContext.getOut();
        try {
           HttpServletRequest req = (HttpServletRequest) 
pageContext.getRequest();
           pageContext.getSession().setAttribute("origPage", 
StringUtils.replace(req.getServletPath(), "jsp", "jsf"));
           loginPage = req.getContextPath() + 
pageContext.getServletContext().getInitParameter("loginPage");
           invLevelPage = req.getContextPath() + 
pageContext.getServletContext().getInitParameter("invLevelPage");
           HttpServletResponse resp = (HttpServletResponse) 
pageContext.getResponse();
           if(!currentUser.isValid) {
             resp.sendRedirect(loginPage);
             return SKIP_BODY;
          }
           if(!currentUser.inLevel(Integer.parseInt(pageLevel))) 
resp.sendRedirect(invLevelPage);
        } catch (IOException e){throw new JspException(e.getMessage());}
        return SKIP_BODY;
    }



currentUser is a class initialized with login page data and a level 
list for user read from DB. loginPage and "invLevelPage" are variables 
set in web.xml.
