RE: problems tracking session from page to page
You have to create a session object first.

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

Why dont you use XSP and then use session object of XSP just as you use
in normal case of JSP page.

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.

Posted by Geoff Howard <co...@leverageweb.com>.
which you can do with the create-session="true" attribute on xsp:page. see
the docs.
