Re: GWT Sticky Sessions


can you please tell if this solution fixed your problem completely by itself? or this worked toghether with the session management code you were talking about.
I'm having a similar problem: the mod_jk load balancer is not redirecting my requests to the initial tomcat (The one he starts "Talking" with) and this happens from the start, even when loading the initial page causing the Login page to have missing components...

Hi All,

I fixed my problem. "Does anyone know how I can pass a plain,
unencoded, jsessionid with all http POST requests which the GWT client
frontend makes?"

In the end I used a servlet filter in order to set a jsessionid as a
cookie for every http response my GWT application made:

import java.io.IOException;
import javax.servlet.*;
import javax.servlet.http.*;

import org.apache.log4j.Logger;

public class JsessionidSetter implements Filter
        public static Logger log = Logger.getLogger(JsessionidSetter .class);

        public void init(FilterConfig arg0) throws ServletException

        public void destroy()

        public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException
                HttpServletResponse response = (HttpServletResponse) res;
                HttpSession session = ((HttpServletRequest)req).getSession(true);
                response.addCookie(new Cookie("JSESSIONID", session.getId()));
                chain.doFilter(req, res);

With supporting xml in my web.xml:
