Hi!
We are using cocoon 2.2 and hibernate. I am not sure if we choosed the
optimal way to integrate these both, but for us it works.
We configured all database connections via spring as DataSource, and
these we use further on for the hibernate session factories and for the
old avalon data

Hi,
I was wondering if someone who uses Cocoon 2.2 and Hibernate could
provide some tips on using Hibernate and Cocoon 2.2 together? For
example, how do others configure the connections, call in the DAO (eg
using Spring or calling them directly), etc...
An example would be nice.
Thanks
is the so-called CHS
(Cocoon-Hibernate-Spring) approach first introduced here [1]. Of course
it requires for your project to rely/depend also on Spring, but I think
that this can only be a plus, also because of the very recent release of
Spring 2.0.
As properly described here [2] (these slides were
I was wondering if anyone had advice or opinions on
using Hibernate+Flow+Cocoon? I'm writing a small test
application to understand the issues involved, and I'm
not quite clear where the SessionFactory should be created.
According to the Hibernate documentation it's a relatively expensive
and committed. I do not use flow to create the SessionFactory.
To access the session, I depend on the repository pattern where the
current session is obtained from the SessionFactory.
Hope this helps,
Andre

Hi Joseph,
a very well established best practice in using cocoon flow (flowscript
or javaflow) with Hibernate is the so-called CHS

that this can only

I'm thinking of using the Hibernate XML export feature to load objects
into my pipeline (inside a transformer). I'd certainly appreciate
hearing about any
more flexible. Imagine, you can also throw it anyplace in
your pipeline and have it operate on just the namespace it uses. (I'm

I assume you've seen
http://wiki.apache.org/cocoon/CocoonAndHibernateTutorial and the other

of these use Hibernate by calling it from Flow to get back a javabean
and use that in jxtemplate/cforms. I

Thank you very much for your help. Your mentioning the Configuration

Yep, that is strange. But I really couldn't get it otherwise to work.
I'm doing this on plain cocoon (no tomcat or other app server)
ok, next time I will read more thoroughly :)
You needed to call configure() because you are using the
hibernate.cfg.xml file,
as opposed to hibernate.properties used by me and in the tutorial, which
is read
automatically when the session is created.
I will add this information to the page.
post the source code of your
HibernateFactory class ?
Did you add a statement like the following;
cfg.addClass(my.test.Mutex) ?
How did you add your classes to the hibernate configuration before ?

I'm wondering what might be the advantage of
using Hibernate - or another O/R mapper - together
with Cocoon.
There some articles on the web, about using
Hibernate with Cocoon.
And anyone using it?
