There are two ways how a servlet-container can deal with HttpSessions: The one way is to transfer a cookie with each request (you do not have to programm this, this is the default behaviour of at least most of the JSP-/Servlet-Containers) or you have to use URL-Rewriting which needs additional programming but has the advantage of not relying on cookies on the client-side.
Therefore it is highly probable that you are using cookies as a means to deal with cookies. For the CookieyManager to work properly you have to know the cooky-name. Tomcat and JRun use "jsessionid" as the name of the cooky by default. You should try with this one in the CookyManager. Greetings, Wolfram
