it does deal with anonymous fields, but only in conjunction with 1:1 references. Please post class-descriptor and source for Customer, Car.

Hi Armin.
okay i didn�t know about 1.0rc5 isn�t dealing with anonymous-keys.
so i do like suggested in 1:1-mapping.
but then in my Beans i have int carId Car car;
i do now: setCar(Car c){ car = c; carId = c.getId(); }
but i think this is redundant, isn�t ? now i am very confused on dealing with OJB...
a short, and last question, why doesn�t OJB1.0.rc5 not deal with anonymous-keys i thought its a nice feature!
greetings ralf

Hi Armin, thanks for your patience, first! but the things with declaring PK_Fields i read at:
=== message truncated ===i did everything like told me :-) the document is written nice and understandful,
doh! Assume the current implementation doesn't
achieve this. All anonymous keys are held in an internal map using the
object itself as key. Reading will be successful, but when the object
e.g. will be serialized and then returned to OJB the anonymous PK
field will never be found (object does not match a key), its only
possible to extract the FK from the associated reference object.
Thus I think anonymous keys will only work in
conjunction with 1:1 references.
I don't write the 'anonymous-key' stuff, so maybe I
overlooked an important argument.
regards, Armin
but only the little thing froeign-key is null in my case...
did you know if this sample is available? i didn�t found it in src-distribution.
thanks alot!

Hi
Ralf,
but in my case the own id�s of a class where anonymous too, is that the matter?
AFAIK we don't have a test case that mix this
stuff.
Think it is not allowed to declare a PK field
anonymous.
Recommend you to setup a test case similar to the
examples in test suite or docu
(http://db.apache.org/ojb/tutorial3.html#Mapping
1:1
associations). As recently as your test pass start to tweak ;-)
regards, Armin

Hi Armin, again... ...sorry...
i looked in samples you told me! (thanks for tipps!) but i have all so like 1:1-relationship org.apache.ojb.broker.ObjectRepository$Group org.apache.ojb.broker.ObjectRepository$Componente (access="anonymous" for reffered ids) but in my case the own id�s of a class where anonymous too, is that the matter? but i don�t think so, because for car and customer a id is "generated".
But only!!! the reffered id (in customer for car is "null")
...strangely... isn�t it ?
perhaps i can send it to list / to you? (i asked, because i will not blow up list with my (i think) foolishness)
thanks for your patience! ralf --- Armin Waibel <[EMAIL PROTECTED]> schrieb: >
Hi
Ralf,
Ralf Bode wrote:
hi ... again :-(
it is really frustratingly... i turned OTM->true made: customer.setCar(car) broker.store(customer);
I don't know what's wrong with your test, but
this
will definitely work with the PB-api.
You can find many examples in test suite, e.g. ...broker.AnonymousFieldsTest.
regards, Armin
but same... customer is in DB, car not! :-(
i have read in aritcle in german-javamag on OJB there was said "all is nice"
or am i to stuid?
i though it would be possible to store "customer" and his car... has anyone a "runnig"-case for an idot, like
me?
thanks!

Objects
are not automatically stored by reachability
-- the car isn't inserted because it is attached to Customer.
This
*can* actually be done in the OTM if Car is a truly dependent
object
(otm-dependent attribute), but in the PB an object must be
made
explicitly persistent.
broker.store(ca); broker.store(cu);

Hi Brian, now i got an "anonym" id (very nice, so i now have "pure" javaBeans no technicals in it :-)
i made cu = new Custiomer(); ca = new Car(); cu.setCar(ca); broker.store(cu);
now only a customer was in DB
i must add the "auto-*" in descriptor: <reference-descriptor name="car" class-ref="de.ralle.Car" auto-retrive="true" auto-update="true" auto-delete="true">
