Hi Jean-Yves,
I always have a violation of foreign key constraint, because OJB seem's
to try to persists instance of this class before the instance of
Location linked with it.
Is that normal ? Do I have to persists the Location object first, or is
OJB supposed to be able to deal with that ?

Hello,
I would like to try and get started using the OJB product. I am on the website,
but do not see where to begin. So I downloaded this: db-ojb-1.0.3-bin.zip and
extracted it, hoping for some simple webapp example.
Back at the website I tried following the ODGM Tutorial. But it goes
Try the ojb-blank.jar from the same source, it is a blanco
preconfigured project where you only have to add your classes (that
is, for simple projects)
Also related is the Getting starting section of the doc:

The getting started page is probably the most useful.

Do I rename this .jar to a .war and deploy it? Or extract it and check the docs?

I am finally rolling ... a little bit.
I have the ojb-blank.jar and put it into a folder on my drive C:/OBJ_PLay.
Then according to the directions, I extracted it, and renamed it to

eg:

Hi, I Keep Having problems
before the conection
MetadataManager metadataManager = MetadataManager.getInstance();
ConnectionRepository repository =
metadataManager.readConnectionRepository(getXmlconection(servidor));
So is there some trick to running the create-db task in the generator to
create a database in Oracle?
When I run the task I get a The Network Adapter could not establish the
connection. However I know the host name is correct (I'm echoing it out
in the ant target.).
I can ping that host. And I
You could try to do a simple select or the like via Ant's SQL task
(http://ant.apache.org/manual/CoreTasks/sql.html) to see whether the

Hi,
in current OJB version it's not possible to reset the default
connection setting (to avoid side-effects). If try to set the default
PBKey more than one, you will get an exception.
In the OJB_1_0_RELEASE branch I changed this behavior (MetadataManager +
ConnectionRepository). You can patch
Hi,
I'm trying to help one of my developers with a query - and I have to say, I
don't OJB can cope with it at the moment.
Essentially, we want OJB to generate some SQL to do some arithmetic in the

SELECT FROM ... WHERE (COLUMNA + COLUMNB - COLUMNC) = 0

This sounds more like a problem with Torque which is per default used
to generate the tables in the database.
You can try to use commons-sql instead
(http://jakarta.apache.org/commons/sandbox/sql/), it groks the same

foreignkeys

This shouldn't matter, but it's recommended to use

when insert new objects.
