Thank you Armin,
Can I get a nightly build of 1.0.5 somehow?
Currently the easiest way is to check out latest version from SVN
OJB_1_0_RELEASE branch (we don't have a nightly build).
http://svn.apache.org/repos/asf/db/ojb/branches/OJB_1_0_RELEASE/
(http://www.apache.org/dev/version-control.html)
If your IDE doesn't support SVN you can find two SVN-GUI-client projects
on Tigris.org:
http://rapidsvn.tigris.org/
http://tortoisesvn.tigris.org/
It's as easy to use as an ftp-GUI-client.

Armin

Hi Everybody,
We upgraded to 1.0.4 and using JT400-4.4 JDBC driver for AS400 data
source.
See now our JDBC driver throwing exceptions when OJB askes him for
field
named "OJB_CLAZZ", that the result set doesn't have, and it happens
for
every row.
Is it possible to avoid OJB to check for this field from result set?
First, thanks much! This was an important hint to unravel the mystery
of
slowdown of query performance between 1.0.3 and 1.0.4.
Currently OJB checks each row of a result set for this column. The
check
was needed to resolve real class names when inheritance was used.
http://db.apache.org/ojb/docu/guides/advanced-technique.html#Mapping+Eac
h+Subclass+to+a+Distinct+Table+%28table+per+subclass%29
I will check in a improved version tomorrow. This version will only
ask
for the column when it really exists, thus no exceptions should occur.
It's fixed in SVN OJB_1_0_RELEASE branch.
regards,
Armin

Folks,
I am using 1.0.4.
Could you please advice if there is a way to store an object of some
class without storing references although I defined in the
descriptor
of
the class to store references as well.
I am looking for a workaround that will enable me to do it in some
cases...
Something like:
PersistenceBroker.store(object, <some flag to indicate not to store
references>)
you can use a method defined in PersistenceBrokerInternal, simply
cast
the used PB instance to PBI.
public void store(Object obj, Identity oid, ClassDescriptor cld,
boolean insert, boolean ignoreReferences)
This method will ignore the auto-update settings when flag
'ignoreReferences' is true.
http://db.apache.org/ojb/api/org/apache/ojb/broker/PersistenceBrokerInte
rnal.html
Build the Identity via IdentityFactory (service method in PB), lookup
the ClassDescriptor via PB.

Armin
Thank you,
Sergey
