Hi Robert,
there is bug in ODMG-api FK assignment when using
SequenceManagerNativeImpl (using DB Identity columns).
Test case is in CVS and we will try to fix this problem asap.
workaround: use the PB-api to insert new object with 1:1 reference

I guess, that would make a lot of things easier. In my experience, if

Can anyone help me with this?
I have made some changes in my code, and I got one object of two currently
in the db to load correctly. I don't know why the other one does not load.
I'm having the feeling that I am missing something here. Here is my code

Hi,
I am using RC7. Report queries do not convert fields as specified in the
mapping. For example, the field shown here returns as BigDecimal in the
query result. Is there a way to get it converted?
field-descriptor name=procDate column=PROCDATE
jdbc-type=bigint
Does anyone know how to turn native sequencing in DB2? I do get -1 and -2 as values
for that column and at some point(when application is restarted) it complaints that an
attempt was made to insert non-unique primary key.
Thanks in advance.
Max.

I'm using the PB API, and I have data in two separate databases (on two
separate machines). I have an object class in one database that contains
another object class from another database. The problem comes when I set
auto-retrieve on for the containing class -- OJB doesn't seem to realize
that
I've been experiencing the same problem but running on just Tomcat.

hello
I searched the archive and I have not found answers so please tell me:
- is it still impossible to use OJB/JDO in production (because of the sun's JDORI
license) ?
- when apache implementation of JDO will be ready ?
- why JDO api is better than ODMG (I mean functionality, usability) ?
I'm using rc6.0 for now thinking of going to 1.0.0. What version did you upgrade with
to make it work?
Thank you,
Max.

That is my personal plan, not an official one, and is subject to the
