Hi,
verify calling to pb.close, pb.commit transaction method :
if you call pb.close or pb.commit transaction befor sending result of your
query to your business layer you lost
the result set.
hope that help you.

Hi;
i have two mapping file : repository1.xml and repository2.xml.
the difference between these two file are the value of auto-*
[auto-retrieve, auto-update ..] ; at runtime sometimes i need to use
repository1.xml and somtimes the repository2.xml .
what is the best and optimal solution about
= PersistenceBrokerFactory.defaultPersistenceBroker();
so in this situation
B got a broker with profile admin because MetaManager is a singleton.
is right

looking the example :

to make access to the

the dtd from a

any idea .

i think the coste of using ODMG is very big only looking how in ODMG we
query an object. in ODMG it use OQL (like SQL synthaxis where ) so is
very diferent to PB wiche use Criteria to build a condition !
what do you think Mr Armine

Sorry, I don't understand your question. In OJB nested objects can be
used group and encapsulate fields of persistent objects.

Hi,
in ojb document :

Say you use the PB to query an object O that has a collection attribute col
with five
elements a,b,c,d,e. Next you delete Objects d and e from col and store O
again with
PersistenceBroker.store(O);
PB will store the remaining objects
