Hi all!

I have a problem with essions in cocoon. In my pipeline I execute a piece of code in JSP using CINCLUDE transformer. In this piece of code I load some values in the session which ones later I need to get with executing another JSP. (I can't use cocoon's sessions/context because I can't get its values from the JSP code)

In other words, I'll try to explain it better with the code (read the comments please)

this is my pipeline:

<map:match pattern="Almacena.jsp">
     <map:generate type="request">
      <map:parameter name="generate-attributes" value="true"/>
      </map:generate>

<!-- the pipeline starts with an XML which contains the REQUEST details -->
<!-- peticion.xsl is an XSLT that transform the XML to set the correct params to apply the CINCLUDE with the params that identify the URL of the JSP file that I want to execute -->

       <map:transform src="xsl/peticion.xsl">
           <map:parameter name="cms-url"
 value="http://mmarin:8080/pruebasSesion/Ejemplos"/>
           <map:parameter name="url-peticion" value="AlmacenaSession.jsp"/>
       </map:transform>

<!-- I've thought in the posibility of passing the SessionID as a parameter to the JSP, but don't know how to "set the sessionID" in JSP. Any idea?-->

<!-- When I apply the Cinclude transformer, the JSP code RUNS WITH A DIFFERENT SESSION EACH TIME (that's my problem!) -->

        <map:transform type="cinclude"/>

<!-- As I am only proving the way of doing this, I'm using a very simple JSP file which set the values of 2 params (nombre, edad) in the session and returns an XML file which will be transformed by the XSLT "Almacena.xsl" -->

      <map:transform src="xsl/Almacena.xsl"/>

     <map:serialize type="html"/>
   </map:match>

This is the piece of JSP code:

<%@ page language="Java" session="true"%><?xml version="1.0"
encoding="ISO-8859-1"?>
<%@ page import="java.util.*" %>
<%!String nombre;
        Integer edad;
        String sessionId; %>
 <%nombre=request.getParameter("nombre");
        edad=Integer.parseInt(request.getParameter("edad"));
        sessionId = session.getId();
        session.setAttribute("nombre",nombre);
        session.setAttribute("edad",edad);%>
    <AlmacenaEnSession>
        <nombre><%=nombre%></nombre>
        <edad><%=edad%></edad>
        <sessionID><%=sessionId%></sessionID>
    </AlmacenaEnSession>

I get the SessionID so I can prove that it's different of the one I have in the browser :((

Finally I try to recovery the info I've saved in the JSP session using another pipeline similar to this one which execute a JSP code too.
As the session in which the JSP runs is different each time I cannot get the values....

Any idea?

Thanks in advance!!
