You have to create a session object first.   Regards shoaib -----Original Message----- From: Mike Lenyon [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 27, 2003 9:38 AM To: [EMAIL PROTECTED] Subject: Re: problems tracking session from page to page shoaib,   thanks for your response.  the context in which i'm trying to use the session object is xsp.  unfortunately, merely starting my xsp with <xsp:page     language="java"     xmlns:xsp="http://apache.org/xsp"     xmlns:xsp-request="http://apache.org/xsp/request/2.0"     xmlns:xsp-session="http://apache.org/xsp/session/2.0">   causes the error message: java.lang.IllegalStateException: Cannot create a session after the response has been committed     Mike Lenyon ----- Original Message ----- From: shoaib To: [EMAIL PROTECTED] Sent: Monday, May 26, 2003 9:16 PM Subject: RE: problems tracking session from page to page Why dont you use XSP and then use session object of XSP just as you use in normal case of JSP page.   Regards Shoaib -----Original Message----- From: Mike Lenyon [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 27, 2003 4:53 AM To: [EMAIL PROTECTED] Subject: problems tracking session from page to page hi all,   i'm a cocoon newbie.  i created a couple of pages that store values in the session.  i've tried retrieving those values from the session with calls like request.getSession(), but i get an error each time i make such a call:  "Cannot create a session after the response has been committed."   so i think, ok, cocoon will track the session for me from page to page.  all i need to do is use tags like this: <xsp-request:set-attribute name="current-quote">     <xsp:expr>currentQuote</xsp:expr> </xsp-request:set-attribute> and this:   <xsp-request:get-attribute name="current-quote"/>   unfortunately, what i've found is that no state is maintained from page to page just using the above tags.   in the past, using servlets and jsp, i was accustomed to getting the session (by calling request.getSession()) whenever i was ready and storing objects in it and retrieving objects from it.  but with cocoon, i get the afforementioned error each time i call request.getSession().   what am i doing wrong?  what's a better way to track the session from one page to the next?  there are multiple points of entry into my website and i would like to avoid redirecting users to a page where a session gets created.   thanks in advance for your help.   Mike Lenyon
