Re: Will cocoon work in this situation?
I have similar ineterest.
I do generate XML dynamically, in servlet, then save it to file, then
redirect to this xml file.
I would prefer to have Cocoon to take over XML output stream servlet
generates,
rather then taking over the request from browser to xml file.
Anybody knows how?

Re: Will cocoon work in this situation? => XML to PDF on fly in one Serlet, no files, baby
Posted by Gritsenko <vg...@acm.org>.
Brief:
I wanted to generate XML in Servlet dynamically and pass it to Cocoon
somehow
without resorting to saving this xml to file and redirecting user's browser
to URL of this file.
I have found another
(better, easier, safer? than hacking Cocoon Producer)
solution.
Have found but not tried yet :)
See source code attached.
In few words:
I am a Servlet,
I have an XML document in form of String,
I wrap my HTTPRequest and my XML document as String,
into provided CocoonServletRequest,
(I think it tricks Cocoon to think it is a file, since it fakes
implementation of getPAthInfo method, so Cocoon thinks it is a file
and invokes it's FileProducer)
I instantitate CocoonEngine in myself,
I invoke 'handle' method of this engine, while passing to it
my cocoonized wrapped Request,
my own Response.
The effect is that my Response becomes Cocoon's Response, so that whoever
receives it receives what Cocoon produced.
Viktor
PS.
This article have lead me to this solution:

be very careful if you go down this route. if you allow users to put
arbitrary xml data from arbitrary sources into your cocoon reactor, you're
effectively giving them a shell account on your system.

You might check the source code for a producer (start with
org/apache/cocoon/producer/ProducerFromFile) and check out incorporating
your servlet code as a producer instead of generating a file and
redirecting...the configure cocoon.properties to use your producer instead
of the producerfromfile...
for the dynamic xml, consider checking into the producer, with the caveat
that you'll be producing an xml file from a URL instead of from the file as
the ProducerFromFile does...don't remember the syntax right off, but xerces
can read input from a url...
