dynamic query xsp (esql) in portal using javaflow

[José Ferreiro - TSSAG <jo...@tssag.com>]

Hi cocoonist,
 
I am trying to do a form where the user will give an input (later on it
will be the parameter to perform a query in the database).
I am using cocoon 2.1.6 standalone (no apache, no apache tomcat servlet)
 
I wrote the javaflow to implement the form after that I tried to call my
xsp file where the query is.
 
I succeed to do it. I decided then to introduce the form into the portal
(in a coplet) but a problem occurs.
 
When I submit the query any result is returned. And I get the following
error at the logs (core.log file)
 
---------------------- core.log file------------------------------

Did anyone do already this?
 
I mean to make a dynamic query using portal where the input will be
provided by the form.
I already used this with jsp but it seems a bit more complicated with
cocoon. 
 
Is there another simple way to perform this?
 
All comments and suggestions will be appreciated.
 
Thank you.
