Sharing components between Cocoon and servlets
Hi, I am looking to get some more documentation together on integrating servlets and Cocoon and would like to know if anyone has got any production experience of sharing contexts and thus components. I want to have a servlet running in the same web app context as Cocoon and have access to the same resources (e.g. db connection pool) as Cocoon. I have considered a couple fo ways of implementing thus such as creating a new set of objects that reference the same component xconf or using a parent component manager. I have also noted a couple of threads on the lists that talk about using request actions to pass session data to servlets. The only thing about this is that it means the servlet is called via the sitemap and I am not concerned about this happening. If anyone has any views or experience on how they think this is best done then let me know and in return for saving me some investigation time I will add details to the docs.

Session-objects in Cocoon using servlets and jsp
Hi,
we have a major problem and do not know if there is a simple solution.
Hope that
somebody has an idea. The scenario is as follows:
we realized a login as well as some other things using jsp and servlets.
The jsp are read by th jsp-reader
map:match pattern=jsps/*
map:read type=jsp mime-type=text/html src=/jsps/{1}/
/map:match
Furthermore, we have an session-object that is used by the jsps and cocoon
to communicate with each other. Using just jsp and cocoon it is working well,
i.e., the session object can be used from both places (coccoon,jsp with
same session id).
We need to use a servlet to control some processes (i.e., jsp) and,
therefore,have to run the servlet in the same context as the jsp or cocoon.
Currently, the servlet is having it's own session object with its own session id and,
therefore,
the cocoon-process can not communicate with the servlet. Also, the jsps
get the session-object and its id from the servlet and we can not use the
seession-object anymore for the communication.
Is there any way of running the servlet in the same context as cocoon/jsp?
Do I have to declare the servlet in a special way in web.xml or
sitemap.xmap?
I am not sure if the scenario is understandable. Please let me know if you
need more information about the configuration (BTW, we use cocoon 2.0.3).
Thanks,
Torsten

Cocoon and Servlets
Title: Cocoon and Servlets I have seen this subject (Cocoon with Servlets) in a huge number of archive Anyway no one can explain me how my problem can be solved (I do not find the right one !!) The problem is : how can I retrieve java object in a cocoon session ? My example: I have a cocoon XLM / XSL showing a HTML page (That works !) This HTML contains a form which call my Servlet1 (That works !) form action="Servlet1" method=post Your name: input type=text name=thename/ /form This Servlet1 make a senRedirect to ../Cocoon/servlet2 (Good that works) the site map contains: map:pipeline map:match pattern=servlet2 map:generate src="<A" HREF="http://localhost:8080/Cocoontest/servlet/cocontest.Servlet2">http://localhost:8080/Cocoontest/servlet/cocontest.Servlet2/ map:transform src="appl/servlet2.xsl/ map:serialize/ /map:match /map:pipeline The cocoontest.Servlet2 write a xml layout in the generator this one is transformed by the appl/servlet2.xsl and serialized in a HTML page. All this stuff works well. In my Servlet1 I put some attributes in the session: HttpSession session = request.getSession(); session.setAttribute=(test,cocoon is great !!); In my Servlet2 I get this attribute: String value = (String) session.getAttribute(test); This instruction return a null in the String value. Does that means that the session of the first called servlet and the session of the second calling servlet are not the same ? If no: what is wrong ? if yes: how can I put objects in session that can be retrieved by servlets writing in the Cocoon generator ? Thanks a lot for advice and help René Clais
Re: Cocoon and Servlets
I may be wrong, but i assume, the problem comes from the redirection specs in your sitemap: When you call the source http://localhost:8080/Cocoontest/servlet/cocontest.Servlet2 cocoon probably does this by making a http:client call to that resource. This is definitely done in a separate session. What exactly do you want to achieve? Couldn't this be done cheeper by passing parameters in the redirect of your Servlet1 to Servlet2 ? regards, hussayn CLAIS, Rene wrote: I have seen this subject (Cocoon with Servlets) in a huge number of archive Anyway no one can explain me how my problem can be solved (I do not find the right one !!)

Cocoon and servlets (MVC)
Hi, I currently have part of a system working under cocoon. I have some servlets which are called by those pages, working in a different Tomcat context. I would like to bring the two together - mainly for the reason that they use the same session id from tomcat. Since cocoon is a webapp on it's own I can forsee some difficulties (classloaders etc) in trying to get them to run in the same context. I'd thought of trying do it in the ROOT context. I was wondering if anybody has managed to get servlets working under Cocoon as well as transformed XML pages, or has any advice. Or am I wasting time and could just put the servlets into cocoon/WEB-INF/web.xml.
