Are there any Geronimo users here?

Bleeding edge development for OJB v1.1+ is in CVS HEAD, but should also
not be broken. OJB_1_0_RELEASE is maintenance for the last release OJB
and is thus pre-1.0.4 at the moment.
As a rule of thumb, OJB_1_0_RELEASE branch is currently as stable as
v1.0.3
plus some bugfixes and new minor
hi martin,
I have just run several tests with different hints. It works very well,
however, if I don't set a hint, no cursors are used, even with
getIteratorByQuery!
But maybe that's not too bad. If you enable cursors on iterators by
default, MySql users could run into troubles.
I just found
andreas,
ojb selects all columns but creates proxies instead of fully
materialized Article objects.
what related object do you want to prefetch here ?

hello martin,
thanks for your quick response!!
I will re-run again and check peak JVM heap usage before/after and
bring it up on the development list.
with 115000 big data objects and fetchSize=0 (=default behavoir=without
cursor) 97% memory of my jboss system was used (jboss with -Xmx512m)
ok, sorry. I see.
this was an proposal to set the fetch size!

Hi,
Postgres (for example) don't use cursors on default. The PG jdbc driver
loads the entire ResultSet all at once and keeps it in memory! So, even
if you do a getIteratorByQuery the memory load on a large resultset is huge!
You can get around this, if you set the fetchsize on the jdbc
hi,
may someone can help me with the proxies, please!
everything works fine, prefetching works as it should, but when OJB
initially selects the oid's, it does select all fields instead of just
the pk!
let's say, there is a table 'Article' with 200 000 objects.
I have written an Article Class,
hello list,
I would like to clearify, how ojb and jboss handle a transaction in a
managed environment exactly. I'm using Jboss and the
PersistenceBrokerFactorySyncImpl.
I assume, it's is like that:
void func() {
PersistenceBroker broker = getBroker(); -- here the transaction
starts!?
hi list,
I want to do some database cleanup after a particular exception during a
transaction arises.
But when I try to use the broker which gets this particular exception, I
get another exception:
Transaction synchronization failed - wrong status of external JTA tx.

hello all,
I just have tried to compile the snapshot from today with mbean support
and I'm getting this error:
[javac] Compiling 960 source files to

[javac]
/home/talies/workspace/db-ojb/target/src/org/apache/ojb/jboss/PBFactory.java:42:

directory.
AFAIK I removed the jboss mbean classes some time ago. To make the
examples easier to deploy on different appServer, the JNDI lookup was
no longer used.

hello janssen,
i had the same 'problem'. now I put all items in a list, close the pk,
and iterate over the list now.
from my point of view, I would say it was a bug, that ojb has allowed to
iterate with a closed pk.
because there can be no cursor left to iterate over the query.
well, that's

Hi Thomas,
I'm also a newbie to application servers, so a couple of questions are
comming up now.
Do you suggest to leave EJB's aside complety?
I thought I'm supposed to use OJB within EJB's (like the OJB-EJB
examples...)
Are there also disadvantages if I work just with OJB and leave EJB aside?
I'm working myself through the Deployment in EJB based applications -
Tutorial, and finally I'm not sucessfull:(
I'm working with Jboss 3.2.1, Hsqldb 1.7.1 and ojb rc3.
I used the (like suggested..) the SequenceManagerNextValImpl but I was
getting this one:
