Hi Bonnie,
OJB team,
Thank you for the great work on OJB. I have a suggestion regarding
source organization of OJB. Currently most of the sample/test programs
are put into the same package as the core OJB API classes, which is a
bit confusing. Even though source files for test classes are separated

I am seeing an AbstractMethodError (partial stack trace below) in my

Title: RE: problems with batch-mode=true
Hi,
Here is the code that I tested. You can
see that setBatchMode is called before I start
the tx.
try
{
broker.serviceConnectionManager().setBatchMode(true);
broker.beginTransaction();
for (int i = 0; i 100; i++)
{
CustomerInterface
If I am understanding it correctly, it is supposed to be
a way to interface with the underlying batch mode in JDBC.
There, you add insert statements to a batch, and then
execute them all at once. It should save on overhead.
We have to migrate a large customer database, so we
need any overhead
Thanks a lot Bonnie.

Hi,
TransactionExt was introduced after rc4 - so yes, new-and-unreleased. No
idea to the latter.
If you cast to TransactionImpl (as opposed to Ext), you should be able to
access the markDirty method, as this has been available for some time.

Hi Phil,
Using CVS Head and ODMG, you can cast the ODMG Transaction object to
TransactionExt, which provides a flush method. flush() sends out any
pending SQL to the RDBMS without committing the transaction. That way
you gain some coarse control on the order of SQL statements, which
helps to
