Thanks for the very helpful info, both of you!

I agree with Tony - Cocoon does not have good, representative
sample(s) for a solid DB application.. not entirely its fault, of
course,
as Cocoon is not a DB application per se. Integration via Hibernate
and Spring seems to be the way to go - there are lots of threads on
this topic - but, again, although there are some starting tips and
tricks
(scattered through the Wiki and in various mailing list Q & A's ) there
is not one single, solid sample, that is well documented and clearly
explained, to examine. If you ask for more, I guess most responses
would just point you in the direction of the Cocoon/Hibernate/Spring
Petstore code, available in the later versions of Cocoon. Maybe,
one day, someone will have the expertise, time and motivation to write
up a "everything you need to know about DB and Cocoon"... until then,
you'll need to struggle through things on your own, like the rest of us
:-(

Hi Chris,
When I was starting a project that needed to hit databases and use
CForms I picked apart the Petstore sample application.
It shows how you can query databases from flow and push the results to
and from cocoon forms. Its a bit heavy and overwhelming at first but if
you take the time to step through the flowscript you can see how it all
hangs together.
The main drawback with it is that it is only intended as an example
and
suffers from a fair bit of 'concern mixing' as a result. The project
I'm
working on uses Oracle or Informix as its back end and goes OK but all
the database connectivity is handled from within flow which isn't cool.
I'm now poring over the Hibernate tutorials and the
Cocoon/Hibernate/Spring Petstore example in order to handle database
stuff correctly.
The Petstore example will get you going in the shorter term, however.
Just don't rely on the methods gleaned from it to be a robust
solution.
Hope this helps
Tony

Does anyone know a good tutorial on getting started with databases;
hopefully one that uses CForms? I have looked all over, and not
found
one. I am under enormous time pressure, otherwise I probably
wouldn't
ask this here. I've found several links to one on IBM Developer
Works, but I guess they've stopped giving out their content for free,
or something. The tutorial in the "Databases Block Samples" doesn't
use CForms, and also doesn't work, and has a lot of nasty
dependencies, etc.
Any pointers would be appreciated.
Chris
