Problems with double click in coplet links
I found a problem in Portal-fw, a sample that comes with cocoon.
When I make double click or �lots of clicks� in a coplet link, one of two things can happen:
1- I receive a page without some coplets.
OR
2 �I receive an error page.
This instability happens frequently, so help me as soon as possible.
I already tried in cocoon 2.04, cocoon 2.1-dev with tomcat 4.1.12 or 4.1.18, under win 2000, but the problem still happens.

Well, the second idea works fine as i've already tested it and...guess what?
there are 2 different indipendent session.
I put user/pwd values in the session first in the check_login.jsp page, and
then send them via form/action/post/submit to the cocoon environment to let
them be stored in the session of coccon. In this way, i got two session with
the same values that i can retrieve in tomcat or cocoon as for my needs.
This system looks like a bit "non pro". it's just a way of getting round the
obstacle. i don't know if this is the right way.
The first idea seems likely the most useful, but i really CANT have my jsp
be compiled inside the cocoon env.
Just to understand my system i use redhat8, tomcat 4.0.4 and cocoon 2.0.3
I've tryed to have a jsp page be served by cocoon but i got a 505 server
error page....what a tricky situation :)
ill keep on trying....
see ya later
thanks.

yes, you're crossing contexts (which I totally forgot to mention in the
beginning).

that means, that the JSP and the cocoon stuff live in seperate (webapp)
contexts (you can of course let cocoon handle JSPs). thus, the
encodeRedirectURL can't work, of course. note though that the
encodeRedirectURL should be done when redirecting within your webapp. for
url rewriting based sessions, this appends the ';JSESSIONID=...' to the url.
so, not doing this causes losing the session then.
so what can you do? from the top of my head two ideas:
1. let cocoon handle the JSPs
2. deliver the parameters (username/pw) via request parameters/attributes
(don't know if the latter works, though).

Re: AW: Session problems

Unfortunatly the "encodeRedirectURL" did not work :(
It may sounds good i have crossing webapplications.
My goal is to have a single deployment of cocoon under the jakarta dir, and
store all the file of multiple virtualhosts in another directory
(/usr/webapps/.....).
I got it working [maybe it's wrong] configuring the tomcat server.xml to
redirct some requests to the cocoon container and then let cocoon do the
job.
Just to understand the prefix/suffix:
"pfw" is my cocoon environment. it stands for Publishing Frame Work and in
all my virtual hosts uri i know that when calling the pfw i invoke the
cocoon entity.
ex: myvh.com/index.jsp --> tomcat
myvh.com/pfw/myvh/read.pfw -->cocoon [where pfw is a page generated from
sitemap.xmap stored in /usr/webapps/myvh/pfw/sitemap.xmap virtual host
directory]
This is a pice of my server.xml:
<host name="myvh.com" appBase="/usr/webapps/myvh" autoDeploy="0">
<Context reloadable="true" path="/pfw"
docBase="/opt/jakarta-tomcat-4.0.4/webapps/cocoon" debug="0">
<Context reloadable="true" path="*.pfw"
docBase="/opt/jakarta-tomcat-4.0.4/webapps/cocoon" debug="0">
</host>
When i invoke something in the url like myvh.com/pfw/myvh/page.pfw , tomcat
redirect the request to cocoon to process the request.
Cocoon knows what to do :) in the master subsitemap.xmap there's this
fragment code:
<map:pipeline>
<map:match pattern="myvh/**">
<map:mount check-reload="yes"
src=file:///usr/webapps/myvh/pfw/sitemap.xmap" uri-prefix="myvh" />
</map:pipeline>
In the sub sitemap.xamp stored in the myvh dir there's this fragment code:
<map:match pattern="*.pfw">
<map:aggregate element="ALL" >
<map:part src="setup_env.xml">
<map:part src="cocoon:/{1}.xml">
</map:aggregate>
<map:transform src="xsl/{1}.xsl" />
<map:serialize type="html" />
</map:match>
So, after all, do you think i cross? I don't know if this call/over-call
procedure is fine and if this is the cause of my session failure.
Can anyone help?
bye.

my point here was url encoding based session tracking. if cookies are
switched off url encoding is used to keep track of the session (via the
appended ';JSESSIONID=...'). so if you don't encode your urls correctly you
lose your session (in case of url based...).

well, it does (non-believer ;-), at least in 2.0.4. here the snippet from
the session logicsheet:

hy,
i would like to understand, in which context your servlet is running.
Is it located within the cocoon webapp, or is it located elsewhere?
from the redirect url i guess you are crossing webapplications ...
If this is the case, you have another problem with session preserving
over multiple webapps. there are solutions to this, but this is far
from trivial...
If your servlet runs in the same context as cocoon, then i can't see
at the moment, why you loose your session. from the standard
behaviour of a servlet container i would expect, that once a session
is created within one context, this session is kept. I dont think,
that xsp will always create new sessions. if create-session="true"
I would expect, it creates a session, if none is existing, but once a
session is created it should be keep living for subsequent requests...
After having saying this, i bet you cross webapp boundaries ...

AW: Session problems
Posted by Marco Rolappe <m_...@web.de>.
hi roberto,
the reason why your elements are empty probably are the following; the
session accessed in your XSP might be different from the JSP's session.
since you redirect without url encoding the redirect url, the session
probably doesn't survive the redirect. now in the XSP you didn't specify the
<xsp:page>'s attribute create-session="false" (which is handled by the
session logicsheet), which defaults to "true", thus a new session is created
in the XSP.
I don't know if your sessions are cookie or url rewriting based. anyway, you
should be url encoding the redirect url, see inline comments below.

Session problems
Posted by Roberto Cipollini <ro...@humantech.it>.
Hi.
I have a problem with a jsp page and a cocoon page.
I use jsp to simply check a user/password and if all is right then set some
variables in the session.setAttribute.
I then redirect the user to a cocoon page in wich i should grab the session
variable with some xsp-logic commands but....i can't see them!
Ok...all of you are saying "What a stupid newbie" :). I know, but pls, it's
been a lot of headaches trying to solve this but i still.....have headaches.
This is the code inside the jsp page:
********************************
check_login.jsp
*********************************
session.setAttribute( "username", theRealUser );
session.setAttribute( "azienda", theRealFirm);
//pfw is my custom file format :)
response.sendRedirect( "/pfw/rv3/setup_env.pfw" );
**************************************
cocoon page setup_env.pfw
***************************************

the tag <AZIENDA> and <UTENTE> are always empty!!!
Can anyone help this stupid problem?
