Hi,
I would like to have a question, does cayenne have some mechanism for
registering already existing objects (e.g. beans/dataobjects extended
from
_auto classes) without the need of creating new object and then passing
all
parameters from bean to that dataobject (e.g
datacontext.save(DataObject)).
I saw a method objectsfromdatarows so I was thinking about that
similarity.
datacontext.save(DataObject) seems a lot like Hibernate and Cayenne
doesn't work the same way as Hibernate. I'm not quite sure what you
are trying to accomplish there.
Right, Hibernate uses session.save, but when going through datacontext api
it occured to me that it can come handy, it' not that big deal.
If you just want to persist a single object off, without taking into
account any other changes in your original datacontext, just create a
brand new datacontext for that one object and commit it.
I'm not sure if I follow you on this one: you mean to instantiate the
DataContext class? What would it help to clear one?
I have no problem with retrieving current datacontext of web-app.
Now, datacontext creates and registers new object for me which I should
fill with data and commit changes.
I was talking about registering an existing object already filled with
data and then commiting the changes.
And has anybody tried that password rotation mechanism? It isn't working
for
me (can't establish database connection), is there something that needs
to
be done besides setting it in datanode xml?
I assume you are talking about the rot13/47 methods? They've worked
for me in the past. Which version of Cayenne are you using?

I located the problem, sure for 99%. I used v3b1 modeller to reingeneer db
and in mave ni have 2.0.4 dependency. I need to get 3b1
cayenne-server/client. Anyway what is biggest difference between cayenne
server and client, i suppose client could do for simple database handling.
The Cayenne Server module is the most common one you'll use. It is
what you would use in a web application or standalone Java job (such
as a batch job) or even a Swing UI that connects directly to the
database. The Client module is for the Remote Object Persistence
feature, which I doubt you are using. It is documented separately
here:
http://cayenne.apache.org/doc/remote-object-persistence-guide.html

Yep, I already found it and thanks.
