grab OJB from CVS, and try your query again.

Hi,
It looks like OJB cannot fetch correctly records which have a BigInt primary
key with value 0; at least in the following conditions;
- I'm using RC5
- Have a table (here Locations) with a primary key Id with a auto-increment
sequence
- I'm using Oracle 9.2
- The table has a 1-N
Hi,
I reported the same issue some months ago...
The problem lies in the support for primitive data types, since a
primitive type cannot be null, the value 0 is interpreted as null.
It seems that non primitive data types also react the same way (even if
they shouldn't, so from my point of view

Thomas,
Could you give us a short and sweet version of how OJB came to be?

Ok, here it goes.
After working with several proprietary o/r layers I finally got the
chance to work with ODMG compliant OO databases (POET and Objectivity)
in a project.

I'm using a Long object to store the Id, so I thought 0 should be considered
different than NULL. (BrokerHelper.isNull() consider this as null, though).
In the mapping file, the field is declared with jdbc type BIGINT.
I'm normally starting my sequences with 1, but there are places where I use

Hi Dirk,
Can you post the relevant DDL and repository? Is the person-activity relation defined
as a non-decomposed m-n relation? I suspect you have a constraint set in the DDL that
prevents the relation from being stored. As far as the 0 is concerned, do you use a
primitive int or an
Hello,
I've created a mapping like this:

primarykey=true
Hello,

'Vector' is not a good idea. You should use an interface
type such as Collection or List for the type declaration ...
getters and setters...
Hi Wally,
thanks for your response. Below you will find ddl and repository.

I have to do a simple one-to-one mapping with OJB. The key to perform the

Hi,
I am using ojb1.0_rc5, ODMG api with OJB queries, mysql4 (innodb tables)
in Linux Red Hat 7.3 (kernel 2.4.20-20.7).
How can I run a query that returns objects from a different class than
the class to search from? For example:
class Person{
int id;
I find the sun one so annoying to download that I grab it from JBoss
and rename it ;-)

I'm not sure what's the problem in your case, but I think it's OJB. The
