why must i set the PK in my code?
customer.setId(123);
i described it in XML primarykey="true" autoincrement="true"
there is no need to set the PK
but got Errsos, when i dont set up the PK.
hmm, stack trace will be helpful. I assume you use the default sequence manager implementation. These implementation need an internal table for work. You can use an alternative sequence manager, e.g. SequenceManagerInMemoryImpl - see
http://db.apache.org/ojb/sequencemanager.html#SequenceManager implementations

thanks again for a quick ;-)

then setup my project build to extract the generated SQL (the schema.ddl

the tables. I know that this creates a minor dependency between the two
projects, but that's fairly easy to manage. I have no need for
setting up and utilizing torque in my project (I use Axgen to
generate everything from UML), so it seemed like major complications to solve
a simple problem.
YMMV. Larry.

Right now there isn't an *ideal* way to create the
internal tables as
most of the time people don't need them (though
the hi/lo sequence
table is needed enough that this may be incorrect,
since it is the
default sequence manager).
What are thoughts on including the torque
generator stuff in
ojb-blank? The ojb-core schema is already included
in the src/schema
directory, but the build-torque and torque related
jars are not
included. Now that I think about it, I have done
this for all of the
projects I have built around ojb-blank bits
anyway, so that is a
certain argument in favor.
In the short term, Thomas D has has a nice little
walkthrough on
getting torque from OJB setup in the xdoclet docs,
but that is sort of
hidden =) (note, we should probably move that into
its own HOWTO).

Hi to all,
just a question about to install OJB i read, that i have to load the sources and run some build-scripts okay.
but is there an easy-way? i only need a build-script for the binary-version of OJB, that "installs" OJB-internal-tables into database.
or is there a reason for "building" all ?
thanks for advice!
greetings ralf
