Re: tomcat session id
2012/7/15 Elias Kopsiaftis yemi...@gmail.com: thank you, and it wasnt working thats why i asked. there must be something else wrong in my code Session is recognized by sessionid sent either via a Cookie header in HTTP request, or as a path parameter in URL of HTTP request. You can inspect what is actually sent to Tomcat by your client either by using network traffic inspection with a tool like Wireshark, or via configuration of an AccessLogValve in Tomcat. Some references should be in the FAQ. If neither info are sent by your client program, the session cannot not be associated with your request and a new session will be created if a session is needed. (When that happens, a Set-Cookie header will be included in the HTTP response).

Re: tomcat session id
ok i appreciate the input, but for now i will stick with the comet approach because i read that websocket for tomcat 7 is still experimental and i already built a lot of logic around the comet approach. does anyone know the answer to my original question?
