C2 - JSPGenerator and jsp:include
Hi,
I'm having some trouble working with the JSPGenerator.
I'm using a JSP to generate the XML representation of an session resident
object. However, because this object presents some recursive
characteristics, I use the tag <jsp:include>.
The JSP itself works properly. However, when I'm using this JSP as a
generator for Cocoon, I've got the following error:
I've looked at the source (both Tomcat and Cocoon) and it is obvious that it
could not work.
Indeed:
In org.apache.cocoon.components.jsp.JSPEngineImpl, Cocoon wraps the request
in a MyServletRequest implementing HttpServletRequest.
However, when working with include, Tomcat expects a request of the class
org.apache.tomcat.facade.HttpServletRequestFacade
So it generates a ClassCastException.
Any idea how to solve that or how to work around that?
Maybe there is another solution than using the JSPGenerator but the object I
want to render is create by a web application. So I've embedded Cocoon in
that application and I pass the object I want to render to Cocoon within the
session.
I don't want to create an xml file and then call Cocoon because the
application is aimed to be used by a lot of concurrent user and I prefer to
work with objects in memory rather than written in a file.
Thanks for help,
Eric
P.S.: I'm using Tomcat 3.2.3 and Cocoon 2
