Philippe,
Another solution is:
create a new folder and put the conf files here
configure this folder as a source folder
when you build the project, your conf files will be automatically copied in
WEB-INF/classes

Hi,
If you think it's useful, feel free.
As Phil has pointed out, the field-descriptors should be marked as PKs. If
you want to flesh it out a little (maybe chuck in the projects class
descriptor, or at the least the collection-descriptor), or change it any way
- be my guest.
Cheers,
Charles.
The SequenceManager stuff can now be defined per class. Thus it has been
moved from OJB.properties to the repository.xml

Thanks for the detailed answer. That does the job nicely. We had moved

Thanks again,

OJB manages all foreign keys.
In our app, we don't generate setters for any id fields (primary or

find it much harder to fiddle with the keys.

values to use in the sql statement.

When OJB performs the insert/update, it uses the value of "id" from the

A quick google suggests that it is what OJB calls an M:N association (a
