move to the next. If no error, I delete after processing.
So, it's a challenge setting the endIndex() because I never know how many
'error' records are sitting at the top of the queue.

Does anyone know if its possible to do something like this in OJB:
select * from table where criteria but only return me a maximum of 10 records.
Is this possible?

OUCH!! If this doesn't work, the it's a MAJOR problem. Has someone
verified in using the PB API in a multi-system environment? Given that
it's using a database sequence, it shouldn't be a problem. It's got to
be a bug.

If I have a 1..n relationship in my object, eg:
Car--->Parts
and I do something like:
Car car = new Car();
car.getParts().add(new Engine());
broker.store(car);
I expect one record in my Car table and one in my Parts table. Perfect
- that's what I have.
Now, I do a:
car.setParts(new ArrayList

get rid of the transaction... why are you doing a broker.close() before
you starting iterating? Not sure what you are trying to do.
getIteratorByQuery() is a lazy version of getCollectionByQuery(). If
does a count when creating the iterator and a select on each
iter.next().

Turn batch-mode off and then try your test. If it works, you'll need
the fix for this. You can either patch ti yourself, or take the latest
CVS image.

autogenerated keys using the DefaultSequenceManagerImpl are not assigned
on broker.store(obj) using batch-mode=true. I'm wondering if the hash
gets messed up (ordering) on the batch.

Okay, first of all, thanks for the fix Mark. Now that I have it
working, can anyone explain why my performance just dropped about 20%
after turning on batch mode? I reason I wanted a fix is because i was
trying to get some better performance, not worsen then performance!
HELP!!!

See Mark Rowell's posts to see the bug and fix.
Thanks to Mark!!

All my tests run fine with batch-mode off. As soon as I turn it on,

In looking at the documentation, there isn't really anything descriptive
regarding this attribute on collections/references. I'd like to turn it
off, but I'm afraid. Should I be? Can someone help me understand this
a little better so that I know what's going on? Is this a cache thing?

How come I can't do a query and use a reference-descriptor. It should
work. Here's my code.
Criteria crit = new Criteria();
crit.addEqualTo("identifierText", value);
crit.addEqualTo("issuingAuthority", issuingAuthority);
Query query = QueryFactory.newQuery(PersonIdentifier.class, crit, true);

Something to do with the Cache I think. BTW - broker.deleteByQuery
doesn't work but if I get a collection via the same query and delete
each object - works fine.

Anyone see this before?
What I'd like is when I remove an object from a collection that is
referenced by another object, and then store() the object, I'd like the
collection to reflect that. It doesn't seen to work. The add worked
fine.

Person found = PersonHome.getIns
Is there an FAQ out there that'll show me how to use XDoclet to generate
my .xml for my mappings? That'd be great.

BTW - on a subsequent test that does the query again, it fails. I does
only see the 1 record and doesn't build my linked list. Looks like
there is some caching. Anyone know what I'm doing wrong here or do we

I'm having a problem with a very simple mapping. I've went through all
the docs and examples, and afaik, the mappings are right. I'll provide
some context.

Oracle obviously deals with classpaths differently. In Tomcat, you
either deployed the ojb jars contextually or in
$TOMCAT_HOME/server/lib. I'd be that you need to drop them somewhere
where the container knows to look.

I'd love to learn how your using XDoclet with OJB. Are you generating
