Hi,
Just wondering that whether OJB has save point support
so that partial transaction can be rolled back?
Thanks,

Thanks a lot for all of your answers. I just realized
that OJB can convert from JDBC types to Number
(Integer, Long, BigInteger,BigDecimal) automatically.
For example, JDBC type BIGINT can be converted to
either primitive long or Object Long without any
FieldConversion. In this case, I can just use

Hi, All
I am trying to do a simple query against a very large
table with over 200,000 records. I use QueryByCriteria
without any criteria, but settiing setStartAtIndex(1)
and setEndAtIndex(2). Then I use getIteratorByQuery to
get the result. However, I got OutOfMemory error.
I tried the same thin

I am trying to know the performance difference between
mapping number column to long vs BigDecimal. I did
following test.
1) I loaded over 200k records in the table.
2) I ran a test to retrieve all records in the table
as an iterator and then loop over the iterator to get
each element and
Hi, All
I have a data base column. The data type is number
(10). It is nullable. The JDBC type defined in
repository is BIGINT and the corresponding java type
is long (default). Can anybody tell me how to save a
record so that the value of that column is null
instead of zero?
Thanks,

I am using OJB rc5. Everything is fine when I use it
for stand alone program. But when I try to use it in a
web application (applciation server is resin 2.1.10),
I got following error. From the log, we can see that
there is a NullPointerException at

Hi, all
I have a problem when I try to insert an object in a
data base table and then try to retrieve all records
from that table. I use the same persistence broker for
the above two operations. I found that if I don't
commit the transaction after save, the retrieved
records won't include the new

bind variables and how to do that?
