Hi Thomas,
I am not familiar with ODMG but I will go to study
it. One question needs your help, is it meant that in
the mapping file for this DListImpl I do not need to
configure the attribute element-class-ref for
collection-descriptor tag?

Hi,
I have been using OJB for some period. I am taking a
project left by a partner that uses Hinbernate for
persistence. So I start studying Hibernate. Hibernate
has a mapping function called "any type mapping" that
is defined as the follows:
"The mapping element defines a polymorphic

(NullPointerException is thrown in hashCode()

Hi,
A bug at line 135 of ObjectReferenceDescriptor.java

Hi Armin,
Attached are two files. One is PersistentFieldImpl. It has passed NestedFieldsTest
test with path separator '/' instead of '::'.
The other is SunOneTransactionManagerFactory.java.
Ps, I find I cannot attach files from my yahoo mail. So I send this message from
another mail.

Hi,
Attached is transaction manager factory
implementation I used for SunOne Ap7.
Just wonder how to contribute code? Is the way I am
doing right? Or should I post it to dev mailing list?

Hi,
Here I have a lot of thinking about refactoring
FieldConversion interface to enhance anonymous fields:
1. Since anonymous fields have no corresponding java
fields, their values must come from some other places.
As I know, it can come from

b. ref

Hi,
When I read OJB source code, I find a ClassHelper
class, but it seems that its usage seems not wide.
What I mean is that there are many codes in OJB doing
object instantation do not use it but have their own.
There are ways to instantiate a new object in java.
The simplest one is Class.newIns

Hi all,
On inheritance mapping to one table, a field
'ojbConcretClass' is need in AB abstract class. Is it
still needed since we can treat this field as
anonymous?

Hi,
I just read discussion on tss website

I find that ojb has similar problem "reference id

Hi,
I usually use Map when a object in collection is
needed to be retrieved by key and the collection is
too big to scan the collection to get the wanted

Hi,
I do not really understand what you want to ask. I
just have a class with a java.util.Map field and try
to map it. Do people NOT use java.util.Map in object
modeling?

Hi,
In OJB document, I can find information on how to
handle collection mapping. However, I can not find
information on how to handle java.util.Map. Is it
supported?

Hi,
As stated in Martine Flower's artice
(http://martinfowler.com/eaaCatalog/embeddedValue.html)
"Many small objects make sense in an OO system that
don't make sense as tables in a database. Examples
include currency-aware money objects and date ranges.
