Subject Re: Can't use Cookies in tag libraries ?????
Date Tue, 02 Oct 2001 12:12:44 GMT
Hi

With Tomcat 4.0 I have developed a taglib for visit cookies. The 
relevant part of the code is very similar to what you sent:

        HttpSession session=pageContext.getSession();
        HttpServletRequest 
request=(HttpServletRequest)pageContext.getRequest();
        HttpServletResponse 
response=(HttpServletResponse)pageContext.getResponse();
       if(session.isNew()) {
            String cValue=getCookie(request.getCookies(), 
name).getValue(); // getCookie is an auxiliary function
            session.setAttribute(visit, cValue);
        }
        Cookie cookie=new Cookie(name, getTimestamp());
        cookie.setMaxAge(expires);
        response.addCookie(cookie);

(this code belongs to a tag libray)

And it seems to work without problems.
