Should I just be setting up ObjectCacheEmptyImpl instead of
ObjectCacheDefaultImpl? Is that enough?
Yes, this should be enough.
(And it's recommended to use an database based sequence manager
implementation, like SequenceManagerNextValImpl
Hey all, the mail archives are not working properly atm, so I'm sorry for
the post, but I'm wondering how to handle grabbing the min/max in a query
without doing a comparator on the returned List?
Many Thanks!

The first rule of intelligent
Report queries do not return materialized objects !
The iterator.next() returns an object array (Object[]) consisting of the
columns returned from your query.
In your code, it would be a one dimensional array containing the value of
the column that is mapped to Workstation.workstationType
Pretty much, yes...
Of course, you should be able to work out which class of object it is and
cast it appropriately (e.g. if workstationType column is a VARCHAR, cast to
string etc.)

All,
I'm playing with Ojb and the Kategorien/Artikel tutorial. I noticed that
when I ask 3 times the same request to the database, I have this error
below.
Why it is not possible to request more than3 time the same request to the
database? ???

The Collection (DList which is changeable from the OJB.properties) DOES

I should add that a DList or Collection of some type is returned is
actually a good thing. Why? Take a scenario where you have a User
object and we're returning a User object from OJB. You use that object
all over your code. One day you decide to change the User object and
call is People.

When we do a lot of inserts at once, it seems like OJB does a lot of
pre-querying. I think this is for deciding whether a new object
consistutes an UPDATE or an INSERT. For mass-loading of objects
(which we know will be new unique INSERTS). Is there anything we could do
to optimize the
Have you tried 'broker.store(article, ObjectModificationDefaultImpl.INSERT)'. The
optional second argument to store tells OJB whether it is an update or an insert.

I noticed a strange anomaly when using OJB with auto_increment fields in
MySQL. After doing a few inserts of new objects, the auto_increment field
has values in the hundreds. Is this behavior normal or is there something
going awry?
Any help is appreciated. Thanks!

Hi Chuck,
Could you post a little more info.
Which OJB version?
Which sequence manager implementation do you use, or
post your repository_database.xml file (if you use one).

Maybe this can help you.
Thomas,
Create a new cache class which extends ObjectCacheDefaultImpl; you just need
to override one method:
public void cache(Identity oid, Object obj) {
if (oid.getObjectsClass() /* should be cached */) {
super.cache(oid, obj);
}
}
It might make more sense
Hi,
Thanks for the advice but I am not sure the grab size attribute of the

From my understanding it is only related to OJB default SequenceManager and

so, if your driver/db combo support cursoring, setting the begin and end index will
allow you to just display a window of results. The efficiency is based on the db, but
it's worked for us on SQL Server and Oracle so far.
OJB will execute the query, then use the cursor to
