I'm encountering a problem materializing objects with
type LONG in the current release of Jakarta OJB 0.9.8
under Oracle 8i.
I have the ConnectionManager configured to be of type
org.apache.ojb.broker.accesslayer.ConnectionFactoryManagedImpl.
Furthermore, the repository.xml i have uses a JNDI
data source running under Weblogic.
This only occurs when I have declared a field to be of
type LONGVARCHAR and this occurs under Oracle 8.1.7.
It looks like either the ConnectionManager is
prematurely closing the resultset prior to complete
materializeObject() - it seems to fail under
getManagedCollectionByQuery().
I noticed a m_eager_release flag under the
ConnectionManager - could this be the culprit? I
think this may also be related to the junit test
errors under Oracle.
The following is a stack trace:
java.sql.SQLException: Stream has already been closed
