Hi,

So first thank a lot for your helpful reply ,
example :
Class A {
long id;
B bObject;
}
Class B {
String name
String phone;
}
In TABLE A :
-----------------------------------
BIGINT id;
STRING name;
STRING phone;
in this case we can use nested object in order to encapsulate field name
and phone from table A in Class B. ok .
but in case of 1:n :
-------------------------------
Class A {
long id;
Collection bObjects; [Collection of B].
}
so my question is possible to use nested objects , if yes how can i use it
????
No, because "nested objects" and a 1:n reference are completely
different concepts. In the first case a "nested object" is used to group
data of one table. In the second case you have two different tables A
and B with a 1:n reference between A and B.

Armin
thank in advance.

Sorry, I don't understand your question. In OJB nested objects can be
used "group" and encapsulate fields of persistent objects.

Could you describe more detailed what you mean.
