Hi,

I am using OJB 1.0 as the persistence layer to do the
actual insertion/update into database. I found that I

I'm using the PB API, and I have data in two separate databases (on two

DB2 UDB also supports "GENERATED BY DEFAULT AS IDENTITY" columns. How can I make it
work with OJB?
The implementation I'm looking for is the one that leaves PK as null at the time of
insert. I realize that it might be impossible to do in the framework that tries to

Hi,
I am using RC7. Report queries do not convert fields as specified in the
mapping. For example, the field shown here returns as BigDecimal in the
query result. Is there a way to get it converted?

It means that something isn't set correctly in the database.
This has happened to me many times. It always happens when I turn on
"native" sequencing (IDENTITY in MSSQL or AUTOINCREMENT in MySql). Check
the PK of your database, it might not be properly set to increment.
Whenever
this isn't set
I experienced exactly the same problem running in managed environment with JTA
transaction.
